Background
Analysis of mutations in the epidermal growth factor receptor gene (EGFR) is important for predicting response to EGFR tyrosine kinase inhibitors. The overall rate of EGFR mutations in Korean patients is variable. To obtain comprehensive data on the status of EGFR mutations in Korean patients with lung cancer, the Cardiopulmonary Pathology Study Group of the Korean Society of Pathologists initiated a nationwide survey. Methods: We obtained 1,753 reports on EGFR mutations in patients with lung cancer from 15 hospitals between January and December 2009. We compared EGFR mutations with patient age, sex, history of smoking, histologic diagnosis, specimen type, procurement site, tumor cell dissection, and laboratory status. Results: The overall EGFR mutation rate was 34.3% in patients with non-small cell lung cancer (NSCLC) and 43.3% in patients with adenocarcinoma. EGFR mutation rate was significantly higher in women, never smokers, patients with adenocarcinoma, and patients who had undergone excisional biopsy. EGFR mutation rates did not differ with respect to patient age or procurement site among patients with NSCLC. Conclusions: EGFR mutation rates and statuses were similar to those in published data from other East Asian countries.

Abstract PDF

BACKGROUND
Rapid and sensitive detection of KRAS mutation is needed to maximize the benefits for patients who are being treated with monoclonal antibodies to target the epidermal growth factor receptor in colorectal cancer. The aim of this study is to evaluate the efficacy of the peptide nucleic acid clamp real-time PCR (PCqPCR) as compared to that of direct sequencing (DS) between using fresh colorectal cancer tissue and the matched formalin-fixed and paraffin-embedded (FFPE) colorectal cancer tissue.
METHODS
The efficacy of PCqPCR was evaluated and compared with that of DS using fresh tissue and matched FFPE tissue from 30 cases of colorectal cancer.
RESULTS
PCqPCR is more sensitive than DS for detecting KRAS mutation. PCqPCR detected 1% of mutants in 1 ng DNA. PCqPCR detected mutation in 1% of mutant cells, while DS barely detected, by manual reading, that in 20-50% of mutant cells. In the clinical samples, PCqPCR detected KRAS mutation in 60.0% while DS detected KRAS mutation in 53.3% of the colorectal cancers. The two methods showed a 100% concordance rate for detecting KRAS mutation between the fresh tissue and FFPE tissue.
CONCLUSIONS
The PCqPCR method is efficiently applicable for the detection of KRAS mutation in a clinical setting.

Abstract PDF

Congenital cystic lesions of the lung are uncommon and a conjunction of two or more lesions is very rare. We report here on a case of coexisting intrapulmonary bronchogenic cyst and congenital cystic adenomatoid malformation in a 13-year-old female with a cystic mass in the right upper lobe of the lung. Computed tomography showed a cystic lesion measuring 2.5 cm with an air fluid level and surrounding multicystic lesions in the right upper lobe. On gross examination, the cut surface showed a cystic mass containing inspissated mucinous material, and the cystic mass was surrounded by multiple small cysts. Microscopically, the larger cystic cavity was lined with pseudostratified ciliated columnar epithelium. The submucosal tissue contained mucinous glands and plates of cartilage. The surrounding smaller cysts or irregular spaces were lined with bronchiolar-type respiratory epithelium. We propose that this hybrid lung lesion may represent the missing link in a common embryologic pathway determined by the timing of mesenchymal and epithelial interactions.

Abstract PDF: We report a case of spindle cell epithelioma, a so-called benign mixed tumor of the vagina. The patient was a 35-year-old nulliparous woman who presented with a polypoid mass in the posterior wall of the lower vagina just above the hymenal ring. The tumor was relatively well-defined with an expansile margin and composed of stromal-type spindle cells with a myxoid stroma arranged in short fascicles and an irregular cord-like or reticular pattern. A few glandular structures lined by cuboidal cells with squamous metaplasia were also noted. Cellular atypia was not conspicuous and mitosis was not found. We examined this tumor immunohistochemically to identify the histogenesis. The coexpression of epithelial and mesenchymal markers in stromal-type spindle cells suggested a multipotential cell origin for this tumor. The patient has been well with no signs of recurrence during the 12 months after surgery.

Abstract PDF

BACKGROUND
S100A4 has been implicated in invasion and metastasis of various malignant tumors. The aim of this study was to investigate whether or not S100A4 plays an important role in non-small cell lung carcinomas (NSCLCs).
METHODS
Sixty-seven patients with NSCLC including 37 with squamous cell carcinomas (SCCs) and 30 with adenocarcinomas (ADs) who had undergone surgical resection were analyzed. S100A4 expression was analyzed by immunohistochemistry using tissue microarray blocks.
RESULTS
S100A4 expression was positive in 56 (83.6%) of 67 NSCLC cases. ADs were more frequently S100A4 positive than SCCs (p = 0.017). However, no significant correlation was observed between S100A4 expression and age, gender, pT, pN or tumor, node and metastasis (TNM) stage. Two distant metastatic cases revealed an S100A4 positive reaction. Kaplan-Meier survival curves with the log-rank test showed no correlation with 3-year survival (p = 0.782) or 5-year survival (p = 0.227) in either group of patients according to S100A4 expression.
CONCLUSIONS
S100A4 expression was not correlated with age, gender, pT, pN or TNM stage or survival in patients with NSCLCs. Therefore, S100A4 expression may not be useful as a prognostic marker for NSCLCs. However, S100A4 expression showed a higher positivity in ADs than in SCCs.

Abstract PDF

Mucinous tubular and spindle cell carcinoma is a rare low-grade renal cell carcinoma, which was first described as a new entity in the World Health Organization 2004 classification. We report here on a case of this tumor with very unusual aggressive behavior. A 73-year-old man presented with gross hematuria. A computed tomography scan demonstrated a 5 cm sized low density mass in the left kidney. The radical nephrectomy specimen grossly showed a well demarcated tumor confined to the renal parenchyma. Histologically, the tumor consisted of elongated tubules or trabeculae of oval to cuboidal cells with a low nuclear grade, and these tubules/trabeculae were separated by abundant acidic mucinous stroma. In some areas, spindle cell components were mixed with parallel tubules. Neither significant atypia nor mitosis was seen. The patient developed multiple metastatic pulmonary nodules 2 months later. Four months after the surgery, the left supraclavicular, right hilar and right subcarinal lymph nodes were also enlarged by metastasis. The patient died of respiratory failure 13 months after the operation.

Abstract PDF: Calcifying aponeurotic fibroma is a rare soft tissue tumor that mostly occurs in the distal extremities of children and adolescents. We report here on a case of calcifying aponeurotic fibroma of the right elbow in an 8-year-old boy, and the tumor was diagnosed by surgical excision. The patient complained of painless swelling and mild limitation of the range of motion of the elbow joint. Radiologically, the mass was ill-defined and showed stippled calcification with shallow bony erosion. Microscopically, the tumor was composed of spindle cells with nodular deposits of hyalination and calcification, and these deposits were surrounded by palisading polygonal plump cells. Immunohistochemically, the tumor showed a diffuse positive expression for CD99 and negativity for smooth muscle actin, S-100 protein and CD34. The patient has been well with no signs of recurrence during the 42 months after surgery.

Abstract PDF: Endomyocardial biopsy (EMB) is a valuable diagnostic procedure for the surveillance of cardiac allograft rejection. Interpretation of individual cases is still problematic due to variations of findings for grading of rejection and other associated lesions. We reevaluated an experience on endomyocardial biopsies to develop better diagnostic criteria for rejection and other complications. Immunohistochemical studies against cytokines were performed to assess the usefulness of the method for the diagnosis or researches. A total of 249 EMBs taken from 33 cardiac allograft recipients were reviewed. There were 25 males and 8 females. Dilated cardiomyopathy was present (24 cases) and valvular heart disease (4 cases), restrictive cardiomyopathy (3 cases) were also common conditions. We applied the grading system of the International Society for Heart Transplantation (ISHT) for the assessment of acute cellular rejection. Grades of 0, 1A, 1B, 2, 3A and 3B were 39.0%, 28.1%, 11.2%, 11.5%, 12.4% and 1.6% respectively, but 3.2% were inadequate. Thirty five episodes of grade 3A or 3B were present in 17 patients. The response to therapy was assessed using a next follow up biopsy, which revealed resolving or resolved rejection in 85% of patients. The intensity of immunohistochemical stains for IL-6 and TNF-alpha was increased in proportion to the histologic grade but Quilty lesion and cardiomyopathy also showed a positive reaction. The other pathologic findings were ischemic change, previous biopsy site, interstitial edema and fibrosis, and Quilty lesion. These findings showed usefulness of endomyocardial biopsy not only for the evaluation of cardiac allograft rejection but also for the diagnosis of associated cardiac lesions. Immunohistochemical study of the cytokines was related to the degree of inflammation rather than degree of rejection.

Abstract PDF: Somatostatinoma is rare endocrine tumor that was first described in 1977 by Ganda et al. and Larsson et al. simultaneously. It seems nonfunctioning at clinical level. But it may present with diabetes, diarrhea, cholelithiasis, steatorrhea, indigestion, hypochlorhydria, and anemia. In contrast with pancreatic somatostatinoma, duodenal somatostatinoma, in general, is clinically silent. Duodenal endocrine tumors show similar histologic pattern. Therefore, the definite diagnosis is performed by immunohistochemistry and electron microscopic examination. We have experienced a case of somatostatinoma of duodenum in a 62-year-old male. He has complained generalized pruritus for one year and jaundice for 2 weeks. Grossly, the mass was a intraluminary protruding, polypoid lesion with focal mucosal erosion at immediately distal to Ampulla of Vater. Histologically, it showed tall, cylindrical cells with distinct cell membranes, having granular cytoplasm and small innocent looking nuclei. No mitosis was seen. The tumor cells were arraged in small solid groups and trabeculae, separated by fibrovascular stroma. Immunohistochemically, the tumor cells were strongly positive with somatostatin and negative with several other hormonal and neuroendocrine markers. Ultrastructurally, the cytoplasm contains numerous, homogeneous low electron dense secretory granules, which are essentially similar to those seen in normal delta cells.

Abstract PDF: We report a case of angiosarcoma of the jejunum in a 65-year-old female. This angiosarcoma developed 20 years after postoperative irradiation for cervical carcinoma of the uterus. Grossly, the resected jejunum showed a 8 cm long segmental hemorrhagic lesion with multiple, small hemorrhagic nodules or cysts on its serosa and mesentery. Microscopically, the wall of jejunum was infiltrated by epithelioid or polygonal tumor cells arranged in solid nests or lining irregular vascular spaces. The case is of interest that the tumor occurred in the very unusal site for angiosarcoma and the patient had a past history of irradiation for uterine cervical carcinoma 20 years ago. In addition, the resected intestine showed histologic changes of chronic irradiation effect. Therefore, this case supports the view that there is cause and effect relationship between irradiation adn angiosarcoma.

Abstract PDF: Well differentiated osteosarcomas are variants of osteosarcoma composed mainly of fibrous and osseous tissue with minimal cystologic atypia. This tumor may be misinterpretated as a benign lesion if the radiologic and clinical features are not taken into account. We report a typical case of intraosseous well differentiated osteosarcoma occuring in the left distal femur of a 58-year-old woman. Radiologically, it appered as an ill-defined lesion with a mixture of sclerotic and osteolytic ares. But there was a lack of highly destructive appearance of conventional osteosarcoma. Grossly, the mass occupied a metaphysis of the distal femur with extension into the diaphysis and epiphysis. Multifocal cortical destruction and sclerosis were also associated. Histologically, the mass showed typical features of intraosseous well differentiated osteosarcoma. There were various patterns of osteoid deposits and bone formation mimicking those of fibrous dysplasia, nonossifying fibroma or parosteal osteosarcoma.
