Background
Triple-negative breast cancer (TNBC) has a relatively poor prognosis. Research has identified potential metabolic targets, including fatty acid metabolism, in TNBC. The absence of effective target therapies for TNBC led to exploration of the role of fatty acid synthetase (FASN) as a potential target for TNBC therapy. Here, we analyzed the expression of FASN, a representative lipid metabolism–related protein, and investigated the association between FASN expression and Ki-67 and the programmed death ligand 1 (PD-L1) biomarkers in TNBC.
Methods
Immunohistochemical expression of FASN was analyzed in 166 patients with TNBC. For analytical purposes, patients with 0–1+ FASN staining were grouped as low-grade FASN and patients with 2–3+ FASN staining as high-grade FASN.
Results
FASN expression was observed in 47.1% of TNBC patients. Low and high expression of FASN was identified in 75.9% and 24.1%, respectively, and no statistically significant difference was found in T category, N category, American Joint Committee on Cancer stage, or recurrence rate between the low and high-FASN expression groups. Ki-67 proliferation level was significantly different between the low and high-FASN expression groups. FASN expression was significantly related to Ki-67 as the level increased. There was no significant difference in PD-L1 positivity between the low- and high-FASN expression groups.
Conclusions
We identified FASN expression in 166 TNBC patients. The Ki-67 proliferation index was positively correlated with FASN level, indicating higher proliferation activity as FASN increases. However, there was no statistical association with PD-L1 SP142, the currently FDA-approved assay, or FASN expression level.

Abstract PDF

Background
Histoplasmosis (HP) is diagnosed by visualizing intracellular microorganisms in biopsy and/or culture. Periodic-acid Schiff (PAS) and Gomori methenamine silver (GMS) staining methods are routinely used for identification. The acid-fast property of Histoplasma was identified decades ago, but acid-fast staining has not been practiced in current surgical pathology. Awareness of the acid-fast property of Histoplasma, which is due to mycolic acid in the cell wall, is important in distinguishing Histoplasma from other infective microorganisms. Here, we examined acid-fastness in previously diagnosed cases of Histoplasma using the Ziehl-Neelsen (ZN) stain and correlated those findings with other known fungal stains. Methods: All cases diagnosed as HP were retrieved and reviewed along with ZN staining and other fungal stains. We also stained cases diagnosed with Cryptococcus and Leishmania as controls for comparison. Results: A total of 54 patients ranging in age from 11 to 69 years were examined. The most common sites of infection were the skin, adrenal tissue, and respiratory tract. Of the total 43 tissue samples, 20 (46.5%) stained positive with the ZN stain. In viable cases, a significant proportion of microorganisms were positive while necrotic cases showed only rare ZN-positive yeasts. In comparison to PAS and GMS stains, there was a low burden of ZN-positive yeasts. Cryptococcus showed characteristic ZN staining and all cases of Leishmania were negative. Conclusions: Although the morphology of fungal organisms is the foundation of identification, surgical pathologists should be aware of the acid-fast property of fungi, particularly when there is the potential for confusion with other infective organisms.

Abstract PDF

Nodular fasciitis is a pseudosarcomatous reactive process composed of fibroblasts and myofibroblasts, and it is most common in the upper extremities. Nodular fasciitis of the external auditory canal is rare. To the best of our knowledge, less than 20 cases have been reported to date. We present a case of nodular fasciitis arising in the cartilaginous part of the external auditory canal. A 19-year-old man complained of an auricular mass with pruritus. Computed tomography showed a 1.7 cm sized soft tissue mass in the right external auditory canal, and total excision was performed. Histologic examination revealed spindle or stellate cells proliferation in a fascicular and storiform pattern. Lymphoid cells and erythrocytes were intermixed with tumor cells. The stroma was myxoid to hyalinized with a few microcysts. The tumor cells were immunoreactive for smooth muscle actin, but not for desmin, caldesmon, CD34, S-100, anaplastic lymphoma kinase, and cytokeratin. The patient has been doing well during the 1 year follow-up period.

Abstract PDF

Background

Nodular fasciitis is the most common reactive mesenchymal lesion to be misidentified as a type of sarcoma. HuR is an mRNA-binding protein that can stabilize cyclooxygenase-2 (COX-2) mRNA leading to COX-2 overexpression. The aim of this study is a comparison of the expressions of COX-2 and HuR and the relationships between their expressions and the clinicopathological parameters in nodular fasciitis and low-grade sarcoma.

Methods

We measured the expression of HuR and COX-2 in 21 cases of nodular fasciitis and 37 cases of low-grade sarcoma using immunohistochemistry.

Results

The frequency of cytoplasmic immunoreactivity for HuR was 5 of 21 cases of nodular fasciitis (23.8%) and 23 of 37 cases of low-grade sarcoma (62.1%) (p=.013). COX-2 expression was moderate or strong in nodular fasciitis (12/21, 57.1%) and in low-grade sarcoma (29/37, 78.4%) (p=.034). In addition, a significant difference existed between these two entities in terms of the relationship between moderate or strong COX-2 expression and HuR cytoplasmic immunoreactivity (p=.009). Moderate or strong COX-2 immunoreactivity correlated with nuclear (p=.016) or cytoplasmic HuR (p=.024) expression in low-grade sarcoma but not in nodular fasciitis.

Conclusions

This study suggests that HuR and COX-2 expression may be useful to differentiate nodular fasciitis from low-grade sarcoma.

Abstract PDF

Papillary thyroid carcinoma with nodular fasciitis-like stroma (PTC-NFS) is a rare variant of PTC. The term 'PTC with fibromatosis-like stroma' has been used as a synonym to describe this variant. It is characterized by extensive proliferation of fibroblasts and myofibroblasts in the tumor stroma, which occurs in up to 80% of the tumors. We herein describe a case of PTC-NFS which developed in a 49-year-old woman with the demonstration of findings of ultrasonography, fine needle aspiration cytology and histological examination of the lesion. To characterize the stromal components, we investigated the expression of several immunohistochemical markers which have been shown to be expressed differently in nodular fasciitis (NF) and fibromatosis (FM). The immunostaining results demonstrated nuclear and cytoplasmic accumulation of β-catenin, cytoplasmic transforming growth factor-β expression and nuclear Smad expression in the stromal cells, suggesting that the stromal cells in this case have similar molecular profiles to those of FM rather than NF.

Abstract PDF: Eosinophilic fasciitis is a scleroderma-like disease and it may present with paraneoplastic syndrome or as an isolated form of the disease. We report here on a case of eosinophilic fasciitis in a 20-year-old woman who presented with an abrupt onset of subcutaneous limb swelling and peripheral eosinophilia. Pathologically, the specimen was characterized by acute inflammation and thickening of the collagen bundles in the reticular dermis and superficial muscle fascia in addition to the overlying intraepidermal blisters that contained many eosinophils. Eosinophils, some lymphocytes and plasma cells were infiltrated in the superficial muscle fascia and subcutaneous fat. The diagnosis of eosinophilic fasciitis was confirmed by biopsy. It is intriguing that eosinophilic fasciitis showed the microscopic findings of intraepidermal blister with predominant inflammation, and the patient showed a good response to steroid therapy.

Abstract PDF: BACKGROUND
Fascin is associated with motility in various transformed cells. Overexpression of fascin is known to aid in the progression of some cancers and is associated with a poor prognosis. E-cadherin is a major protein of epithelial cells and its expression is involved in the regulation of cell proliferation and differentiation. The aim of this study was to determine the expression pattern for fascin and E-cadherin and how it is related to the prognostic factors for renal cell carcinoma (RCC).
METHODS
The expression of fascin and E-cadherin was evaluated in 208 RCCs including 175 clear cell, 20 papillary, and 9 chromophobe types using tissue array analysis.
RESULTS
The expression of fascin increased as the tumor stage (p=0.00) and Fuhrman grade (p=0.00) increased. A high positive rate of expression for fascin was observed in cases with sarcomatoid changes (p=0.27). E-cadherin expression was seen in the distal tubules and collecting ducts of normal kidneys with a membranous pattern. The positive rate of expression for E-cadherin increased as the Fuhrman grade increased (1, 0%; 2, 23.2%; 3, 34.9%; and 4, 53.8%, p=0.00). An inverse correlation in RCCs was observed in the expression of fascin and E-cadherin (p=0.026, r=-0.158).
CONCLUSIONS
In patients with RCC, the increased expression of fascin and E-cadherin was positively correlated to poor prognostic factors such as a higher Fuhrman nuclear grade and advanced pTNM stage.

Abstract PDF: A case of hepatic fascioliasis misdiagnosed as metastatic carcinoma was reported. The patient was a 22-year-old woman who had had rectal adenocarcinoma (Duke stage C2), and had been treated by Mile'operation 8 months ago. A computed tomogram(CT) demonstrated multiple low density nodules in the liver suggesting a metastatic tumor. A partial liver lobectomy was performed. The resected liver showed multiple necrotic nodules, which appeared to be abscesses containing eggs of the Fasciola species. Parasitic infection should be considered as one of the possible etiologies of hepatic nodules which mimic metastatic carcinoma either clinically or radiologically.

Abstract PDF: Cranial fasciitis is a rare fibroblastic tumor which shows a predilection for the scalp of young children. We present a child with a rapidly growing mass and lytic skull lesion which on pathologic evaluation was diagnosed as cranial fasciitis. Histologically this lesion was identical to nodular fasciitis which was typically found in the trunk and extremities of adults. Cranial fasciitis is unique in that it may present as a lytic lesion in the skull, but this disease entity is not widely known to pathologists and radiologists, and should be included in the differential diagnosis of fibroblastic lesion occurring in the cranium of young children.

Abstract PDF: Fine needle aspiration cytology (FNAC) is an easy convenient non-invasive method in the diagnosis of superficial palpable masses. The cytologic findings by FNAC of reactive and neoplastic lesions in various organs including breast, lymph node, thyroid, salivary gland, etc., have been described, but, those of soft tissue lesions including proliferative fasciitis are relatively rare to find. We recently experienced a case of FNAC of proliferative fasciitis in the left back of a 72-year-old male. The FNAC smears were scant in cellularity and contained large cells with abundant basophilic cytoplasm, one to two nuclei lying at the periphery, and prominent nucleoli that resemble ganglion cells.

Abstract PDF: BACKGROUND
Fascin-1 is a globular cross-linking and actin bundling protein that provides mechanical support to cellular protrusions and cell motility. The expression of fascin in epithelial neoplasms has been recently reported, but its exact mechanism in cancer is unknown. The purpose of this study was to assess the expression of fascin and its relationship with the clinicopathologic parameters and the other tumor markers in gastric carcinoma.
METHODS
Immunohistochemical stainings for fascin, c-erbB-2, p53 and Ki-67 labeling index were performed in 62 gastric carcinoma specimens.
RESULTS
Fascin-1 protein was not expressed in the normal gastric glandular epithelial cells. It had an expression in 35.5% of the gastric adenocarcinomas. The fascin-1 expression in carcinoma was slightly increased in the well to moderately differentiated tumors compared with the poorly differentiated tumors. The fascin-1 expression was correlated with the c-erbB-2 protein expression. There was no significant correlation with the clinicopathologic factors such as tumor size, nodal metastasis, pathologic stage, p53 protein expression and Ki-67 labeling index.
CONCLUSIONS
This study reveals the possibility that the fascin-1 protein expression in gastric carcinoma may be closely linked with the c-erbB-2 protein expression. However, further study on fascin-1 and c-erbB-2 protein at the cellular level and their clinical relevance is needed.

Abstract PDF: Thyroid papillary carcinoma (TPC) with exuberant nodular fasciitis-like stroma is one of the rare variants of TPC. To date, only 19 cases have been reported in the English medical literature. We report here on the the first Korean case of TPC that contained a prominent nodular fasciitis-like stroma. A 40-year-old female presented with a hard painless right neck mass that had been present for two months. Total thyroidectomy disclosed a solitary nodule in the mid portion of the right lobe that measured 25 x 20 mm. The tumor was well delineated, but it was not encapsulated. Microscopically, the tumor was a typical papillary carcinoma except that large areas of the tumor were occupied by a stroma composed of irregular fascicular spindle cells. The stromal component accounted for 60% of the tumor mass. The spindle cells exhibited neither atypism nor mitosis, and the tumor's extensive stromal cell proliferation resembled the appearance of nodular fasciitis of the soft tissues. Immunohistochemically, the spindle cells were positive for vimentin and alpha-smooth muscle actin, but they were negative for thyroglobulin, thyroid transcription factor-1, S-100 protein, CD34 and desmin, and this represents myofibroblastic features.

Abstract PDF: Background
: Fascin, an actin-bundling protein, has been found in specialized normal cells, including the neuronal, endothelial and dendritic cells, and its expression is known to be greatly increased in various human neoplasms. Methods : Immunohistochemical stainings for fascin, betacatenin, and E-cadherin were performed in normal ovary tissue (n=13), and in benign (n=14), borderline (n=32), and malignant (n=74) ovarian serous neoplasms. We evaluated the fascin expression, and its relationship with the betacatenin and E-cadherin expressions, as well as the clinicopathologic factors. Results : Fascin expression was detected in the majority of the borderline (100%, 32/32) and malignant tumors (90.5%, 67/74), but it was not seen in the normal ovarian surface epithelial cells and the benign tumors (p<0.001). Fascin expression was significantly correlated with the occurrence of peritoneal metastases in the carcinomas (p=0.043). A significant relationship between the expressions of fascin and betacatenin (p=0.046), as well as E-cadherin (p=0.035) was noted. There was no significant correlation with the tumor grade of carcinoma, the FIGO stage, tumor recurrence, tumor-related death and the survival rate. Conclusions : In ovarian serous neoplasms, the fascin expression may be closely linked with tumor progression and metastasis, and it was associated with the up-regulation of betacatenin and E-cadherin.

Abstract PDF: BACKGROUND
The placenta from a pregnancy that is complicated by intrauterine growth retardation (IUGR) tends to be smaller than that from a normal pregnancy. To investigate this difference, we analyzed the telomerase activity, the proliferative activity and the mRNA levels of apoptosis mediators in placentas.
METHODS
In 20 placentas from normal third-trimester pregnancies and 22 placentas form pregnancies that were complicated by IUGR, the telomerase activity was detected by a telomeric repeat amplification protocol assay. The proliferative activity was assessed by immunohistochemical staining using the MIB-1 monoclonal antibody. The expression of the apoptosis mediator was evaluated by semi-quantitative reverse transcription-polymerase chain reactions for fas and fas ligand.
RESULTS
Telomerase activity was detected in 2 (10%) of 20 normal placentas, whereas it was not observed in all tested 13 placentas that were associated with IUGR. The proliferative activity was significantly low in the placentas that were associated with IUGR (7.44+/-2.96%), compared with the normal placentas (11.0+/-3.48%, p=0.002). There was no statistically significant difference in the mRNA levels of fas or fas ligand between two groups.
CONCLUSIONS

Abstract PDF: A 32-year-old housewife who resides in Taegu was admitted in Yeungman University Hospital due to right upper quadrant abdminal pain of 2 mounths'duration. An abdomical CT and ultrasonography revealed a relatively well demarcated low density mass in the right lobe of liver. Right hepatic lobectomy was performed on the clinical impression of hepatoma. On the light microscopic study, the lobulated liver mass showed extensive central necrosis and fibrosis, with large numbers of pseudotubercles therein. The pseudotubercles have distorted helminthic eggs frequently. The submitted common bile duct lymph node also showed a few pseudotubercles. The eggs recovered from the tissue homogenate measured 140~152 micrometer by 75~85 micrometer in size and were unembryonated and light yellow to brown. The eggs were determined as those of Fasciola species. We reported the present case as 11th one of human fascioliasis in korea.
