BACKGROUND
The Src family kinases (SFKs) are involved in multiple aspects of tumorigenesis, such as, proliferation, migration, and angiogenesis, and are involved in the generation and progression of many types of tumors. Furthermore, dasatinib, a general SFKs inhibitor was recently approved for use in chronic myeloid leukemia. This study was performed to evaluate the expression of Lyn, a member of the SFKs, in osteosarcoma tissues.
METHODS
One hundred and sixteen patients with osteoblastic osteosarcoma were selected for Lyn expression analysis. The correlation between Lyn expression in tumor sections and patients' clinicopathologic characteristics and the prognostic significance of Lyn expression were evaluated.
RESULTS
Lyn was found to be expressed in 52 of the 116 patients (44.8%), and Lyn positive tumor was found to be significantly associated with a lytic tumor pattern on plain radiographs (p = 0.04). Furthermore, those positive for Lyn showed longer metastasis free survival (5-year metastasis free survival, 65.2% for Lyn positive and 46.8% for Lyn negative; p = 0.06), though this was only marginally significant.
CONCLUSIONS
Lyn was found to be overexpressed in osteosarcoma tissues, and this overexpression was found to be correlated with osteolysis.

Abstract PDF: BACKGROUND
Ezrin has been reported to be involved in the metastasis of solid tumors in both an animal model and clinical trials. However, questions remains as to whether an ezrin expression is an independent predictor of the event-free survival of liposarcoma patients. METHODS: We analyzed 85 liposarcoma patients without metastasis at the time of presentation. We performed immunohistochemistry with anti-ezrin antibody, and we analyzed the association of an ezrin expression with the clinicopathological variables and event-free survival. RESULTS: Twenty-nine patients (34.1%) showed an ezrin expression. Among the 30 low-grade liposarcoma patients, only one patient showed ezrin positivity. The patients who had an ezrin expression were found to be at a significantly increased risk for metastasis compared with the patients who had no ezrin expression (risk ratio: 3.4, 95% confidence interval: 1.3-9.1). The 10-year metastasis-free survival rate was 26.9% for the patients with an ezrin expression and 86.7% for the patients without an ezrin expression. The ezrin expression rate increased with an advanced tumor grade and stage. CONCLUSION: An ezrin expression is an independent predictor of distant metastasis for liposarcoma. Thus, ezrin has the potential to provide additional prognostic information and to be a novel target for the development of new adjuvant therapies for treating the patients who suffer from liposarcoma.

Abstract PDF: Parosteal lipoma is a rare and generally asymptomatic benign tumor of mature adipose tissue that is located in direct apposition to the external surface of the bone. These tumors are occasionally associated with reactive changes in the underlying bone. The reactive bone formation is generally restricted to the base of the tumor, that is, near the periosteum. We recently experienced a case of parosteal lipoma in the proximal femur, which displayed exuberant bone and cartilage formation, and this led us to a misdiagnosis of chondroblastic osteosarcoma on the initial biopsy. We report here on this case with a special emphasis on making the differential diagnosis from osteosarcoma.

Abstract PDF: Distinguishing small cell carcinoma from other lung malignancies is of great clinico-therapeutic significance. Small cell carcinoma is an aggressive tumor with a tendency to metastasize early. Survival time if untreated is low but this tumor is highly responsive to chemotherapy. We have occasionally experienced difficulties in differentiation between adenocarcinoma and small cell carcinoma of the lung in fine needle aspiration cytology (FNAC). The aim of this study was to investigate the possibility of distinguishing small cell carcinoma from adenocarcinoma of the lung in FNAC. We evaluated cytomorphological features of FNAC specimens from 62 small cell carcinomas and 57 adenocarcinomas from the lung that were confirmed by biopsy and/or immunohistochemistry on cell block. Cytomorphological details of the two tumors were compared. Nuclear smearing and nearly absent cytoplasm were the most distinct findings in small cell carcinoma compared to adenocarcinoma (p<0.05). Necrotic background, architecture and chromatin pattern, nuclear molding and nucleoli were significantly different (p<0.05). Nuclear size, nuclear membrane nature and nuclear size variation however were not helpful in distinguishing the two tumors. Combining several features described above, small cell carcinoma can be properly differentiated from adenocarcinoma on FNAC. FNAC is proposed as a diagnostic tool of small cell carcinoma of the lung in the case of inaccessibility to biopsy, and so may allow the proper therapeutic strategies to be determined in such cases.

Abstract PDF: To study the differentiating cytomorphological features of Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL) using fine needle aspiration cytology (FNAC), cytomorphological features of 16 patients with HL (n=8) or ALCL (n=8) were analyzed. In the initial cytological diagnosis prior to biopsy, HLs were properly diagnosed in 4 out of 8 cases (4 HL, 2 atypical, 2 benign), whereas all ALCL were diagnosed as malignancies. However, correct diagnosis of non-Hodgkin lymphoma (NHL) was made in only two ALCL patients (2 NHL, 1 HL, 1 sarcoma, 4 malignancy without specific type). Overall, the percentage of large abnormal cells ranged from 30% to 90% in ALCL except for one case, whereas it was less than 5% in all 8 HL. A spectrum of atypical cells was more characteristic of ALCL. In contrast, HL showed an sharp difference between reactive lymphoid cells and neoplastic ones (bimorphic pattern). Moreover, the emergence of kidney-shaped abnormal cells or wreath-like multinucleated cells was helpful in diagnosing ALCL. The combination of thesefeatures would be useful in differentiating HL and ALCL. Nevertheless, these two types of lymphomas cannot be definitely distinguished based on cytomorphological features alone. Therefore, the aim of FNAC would be to suggest a specific diagnosis and indicate the need for a biopsy.

Abstract PDF: It is important to recognize the pathognomonic cytologic findings of chordoma, because of overlapping cytologic features between chordoma, chondrosarcoma, myxofibrillary ependymoma, and metastatic adenocarcinoma. We reviewed the cytomorphologic features of 5 cases of chordoma diagnosed by fine needle aspiration cytology at Korean Cancer Center Hospital from 1987 to 2003. Clinical and radiographic findings of each case were reviewed. Four males and one female (29-54 years) had tumors involving the sacrum. Pain was the presenting symptom in 4 cases. The three cases showed moderate to high cellularity. In all cases, typical physaliferous cells with or without cytoplasmic processes were noted. In two cases, the background was myxoid with single scattered cells. Cell clusters showing cord-like arrangement were occasionally seen. The single or clustered cells showed mild cellular pleomorphism with slightly increased nuclear/cytoplasmic ratio. Mitotic figures were not seen. In our review, the recognition of physaliferous cells is the most important feature to diagnose chordoma and to differentiate it from other lesions mimicking chordoma.

Abstract PDF: An alveolar soft part sarcoma(ASPS) is a rare malignant soft tissue tumor, which metastasizes to the lung, bone and brain. Recently, we encountered an unusual case of a metastatic ASPS to the bilateral breasts in a 27-year-old woman. She had undergone surgery for an ASPS in her right thigh two years ago, which metastasized to the breast on three occasions, 15 months, 20 months and two years after surgery.

Abstract PDF: The accuracy of fine needle aspiration cytology(FNAC) for the diagnosis of follicular lymphoma was investigated by a review of 13 FNAC specimens from 10 patients. All patients included in this study were confirmed by surgical biopsy preceded by FNAC. Three aspirates were unsatisfactory because of scanty cellularity. Among the remaining 10 cases, 5(50%) were diagnosed as lymphoma, 3(30%) as reactive hyperplasia, one(10%) as metastatic small cell carcinoma, and one(10%) as granulomatous inflammation. Cytologic distinction between follicular lymphoma and reactive hyperplasia is very difficult with cytomorphology alone. Compared to reactive hyperplasia, the characteristic cytologic features such as relatively homogeneous cellular constituent, paucity of tingible body macrophages and lymphohistiocytic aggregates, and less mitotic activity in follicular lymphoma are important findings to prevent false negative diagnosis. In addition, lymphoglandular bodies are useful in distinguishing malignant epithelial tumor from lymphoid lesion.

Abstract: Protozoa of the genus Cryptosporidium are small coccidian parasite known to infect the mucosal epithelium of a variety of animals including human, causing fatal course in immunodeficient patients as well as self-limited illness in healthy individuals. Various life cycle stages including trophozoite, meront, merozoite, gametocyte and oocyst in infected mucosa are a diagnostic feature. Electron microscopy (EM) provides sufficient findings for genus and species identification of this parasitic organism. The authors presented scanning and transmission EM findings of Cryptosporidium parvum infection in two children: one with acute lymphoblastic leukemia and the other without any evidence of immune compromise.

Abstract PDF: Osteochondrodysplasia is a heterogeneous group of disorders appearing short limbed dwarfism. Because many of these entities are lethal and hereditary, an accurate diagnosis is mandatory. The purpose of this study is to define the clinicopathologic features and radiologic findings of osteochondrodysplasia. We reviewed 29 autopsy cases of congenital short limbed dwarfism, consisting of thanatophoric dysplasia (TD) (12 cases), osteogenesis imperfecta (OI) (12 cases), asphyxiating thoracic dysplasia (ATD) (3 cases), short-rib-polydactyly syndrome (SRPS) (1 case) and hypochondrogenesis (1 case). The gestational age ranged from 16 to 41 weeks. Of 6 fetuses that were born alive, 3 were ATD, 2 were TD and 1 was hypochondrogenesis. TD was frequently complicated by hydramnios. Of 8 cases studied chromosomally, only 1 showed chromosomal abnormality -46XY, inv 9. Intrauterine growth retardation was frequently associated with OI. Pulmonary hypoplasia was present in 23 cases (79%), including all cases of ATD, SRPS and hypochondrogenesis, 11 in TD and 7 in OI. Other associated anomalies were present in 17 cases (59%).

Abstract PDF: The authors analysed 2,653 cases of transthoracic fine needle aspiration cytology of the lung to evaluate the diagnostic accuracy and its limitation. A comparison was made between the original cytologic and the final histologic diagnoses on 1,149 cases from 1,074 patients. A diagnosis of malignancy was established in 38.3% benign in 48.1%, atypical lesion in 2.3%, and inadequate one in 11.9% of the cases. Statistical data on cytologic diagnoses were as follows; specificity 98.9%: sensitivity of procedure, 76.8%: sensitivity of diagnosis, 95.5%: false positive 5 cases: false negative 18 cases: predictive value for malignancy, 98.8%: predictive value for benign lesion, 79.5%: overall diagnostic efficiency, 87.5%: typing accuracy in malignant tumor, 80%.
