    ABSTRACT: To investigate clinicopathological features and differential diagnosis of tubulocystic carcinoma of the kidney. The clinical features, histological and immunohistochemical findings were analyzed in 3 cases of tubulocystic carcinoma of the kidney, along with review of the related literatures. Three patients were males with a mean age of 59 years old (range from 44 to 71 years). All presented with no symptom and their tumors were found during routine examination. The tumor size ranged from 1.5 to 5.0 cm in greatest dimension. The tumors were grossly well-circumscribed without capsules and exhibited a spongy cut surface. Microscopically, all three tumors were composed of tubules and cysts of varying sizes separated by thin fibrous septa. The epithelial lining cells were flat, cuboidal and columnar, with often a hobnail-like appearance characterized by abundant eosinophilic cytoplasm with prominent nucleoli. Two cases showed focal clear cytoplasm. One of the three cases coexisted with a papillary renal cell carcinoma. Immunohistochemically, all 3 cases showed positivity for pan-CK, vimentin, CK19, CD10, P504S, and focal positivity for 34βE12. Two cases showed focal positivity for CK7. Tubulocystic carcinoma of the kidney is a rare kidney neoplasm and occurs predominantly in males. The tumor is characterized by gross spongy appearance and microscopic cysts and tubules often lined by hobnail-like cells and separated by thin fibrotic stroma. The differential diagnosis mainly includes other lesions of the kidney that have a multicystic growth pattern.

    ABSTRACT: To study the clinicopathologic features, diagnostic criteria and prognostic parameters of juvenile granulosa cell tumor of ovary. The clinical and pathologic findings of 7 cases of juvenile granulosa cell tumor were retrospectively reviewed. Immunohistochemical study was carried out in 6 of these cases. The follow-up data were also analyzed. The mean age of the patients was 24 years (range=6 to 53 years). Four patients presented with hormonal disturbance, while 3 patients presented with abdominal pain or swelling. Six patients underwent unilateral salpingo-oophorectomy. Six cases were in stage IA and the remaining case in stage IC. Follow-up information was available in 6 patients and the duration of follow up ranged from 1 to 10 years (mean=4.3 years). Five patients remained healthy, with no evidence of tumor recurrence. One patient died of tumor metastasis one year after the diagnosis. Gross examination showed that the tumor masses ranged from 7 to 20 cm in the greatest dimension (average=13.4 cm). Four of the 7 tumors were mixed solid-cystic in appearance and 2 cases were unilocular cystic in nature. Microscopic examination showed diffuse atypical follicular structures formed by granulosa cells. The granulosa cells contained round hyperchromatic nuclei, without nuclear grooves or Call-Exner body formation (6/7). In one of the cases studied, minor foci resembling adult granulosa cell tumor were also demonstrated. The degree of cellular atypia varied (3 cases with severe atypia, 1 case with moderate atypia and 3 cases with mild atypia). The mitotic count ranged from 1 to more than 5 per 10 high-power fields. Immunohistochemical study showed diffuse positivity for vimentin (6/6). The staining for cytokeratin (AE1/AE3) and calretinin was negative. Four cases expressed CD99 and 1 case was positive for inhibin. Juvenile granulosa cell tumor is characterized by the presence of diffuse atypical follicular structures formed by small round cells, without nuclear grooves or Call-Exner bodies. Rare cases contain minor foci of adult granulosa cell tumor. They can be unilocular cystic in nature. The degree of nuclear atypia, mitotic activity and size of the tumor vary and do not correlate with the risk of recurrence and aggressive biologic behavior.

    ABSTRACT: To investigate the reliability, practicability and limitations of cytopathological scrape method in the diagnosis of superficial lesions of skin and mucosal membrane. The quantity of cells harvested by different collecting methods were compared in 18 cases of malignant tumors of the skin and mucosal membrane. The scrape method was performed in 456 cases, of which 148 cases had corresponding histological specimens. Glass slide scraping provides the most satisfactory cell numbers from the lesions of skin and mucosal membrane. The specificity for diagnosing benign lesion in 37 patients was 100% and that for diagnosing malignant tumors in 111 patients was 92.8% (103). The overall diagnostic accuracy was 94.6% (140/148). The false negative rate, false positive rate and the overall misdiagnostic rates were 7.2% (8/111) , 0, and 5.4% (8/148) respectively. For cytopathological examination of superficial skin and mucosal membrane lesions, the glass slide scraping methodprovides broad applications with high diagnostic accuracy and advantages of simplicity, safety and efficiency. Certain limitations do exist, but can be resolved by histological examination of the lesion.

    ABSTRACT: To describe the relative frequency, morphologic features, immunophenotype and clinical data of different types of B-cell non-Hodgkin lymphoma (B-NHL) and to evaluate the practical application of the 2001 World Health Organization (WHO) classification of lymphoid neoplasms. 369 documented cases of B-NHL were further subtyped according to the 2001 WHO classification of lymphoid neoplasms, on the basis of hematoxylin and eosin staining, immunohistochemistry and in-situ hybridization techniques. Amongst the 369 cases of B-NHL studied, 353 cases could be further classified into 11 subtypes. Diffuse large B-cell lymphoma, extranodal marginal zone lymphoma and follicular lymphoma were the commonest subtypes, accounting for 51.2% (189 cases), 14.9% (55 cases) and 10.6% (39 cases) of all cases respectively. Tumors in lymph nodes were seen in 158 cases (42.8%) and in extra node in 211 cases (57.2%). B-cell prolymphocytic leukemia and hairy cell leukemia were not identified. When comparing the diagnosis based on morphologic examination alone with the diagnosis based on both morphology and immunophenotype, there was a 80% concordance rate. Immunohistochemical study was helpful in reaching the correct diagnosis in many cases and could improve the overall diagnostic accuracy by about 20%. Amongst cases of B-NHL, diffuse large B-cell lymphoma is the commonest subtype, followed by MALToma and follicular lymphoma. While morphologic examination forms the basis for lymphoma diagnosis, immunohistochemical study also plays an important role in further subtyping. A combination of both modalities are sufficient for arriving at an accurate diagnosis in most cases of B-NHL, in keeping with the recommendation of the 2001 WHO classification of lymphoid neoplasms.

    ABSTRACT: To investigate the morphologic features, differential diagnosis, prognosis and histogenesis of papillary renal cell carcinoma (PRCC). Tumors composed of at least 50% papillae and > 1 cm in diameter were included in this study. Light microscopic observation, immunohistochemical assay of EMA, CK7, CD10, Vim, 34 beta E12 by tissue chip were performed. Among 516 cases of renal epithelial tumors 33 cases of PRCC were detected. Grossly, hemorrhage, necrosis and multifocality were commonly seen. Besides typical papillae, inconspicuous papillary patterns, such as trabecular, tubular, micronodular and pseudostratified patterns could be seen. Foam cells and psammoma bodies in stroma, and hemosiderin in tumor cells were characteristic. Tumors were of two major types: basophilic type (n = 10), with small cuboid cell and pale cytoplasm (n = 10), 9 of them were low in Fuhrman grading; eosinophilic type (n = 22) with large columnar cells, rich in eosinophilic cytoplasm, 19 of them were high in Fuhrman grading. The remaining case was of clear cell type. The basophilic tumors were all positive for distal tubule marker EMA/CK7, none for proximal tubule marker CD10, 7 tumors positive for Vim. Eosinophilic tumors were positive for EMA/CK7 (9/22), CD10 (10/22) and Vim (6/22). All the tumors studied were negative for 34 beta E12. Follow-up data were available for 24 cases (mean 37 months) with 3-year survival rate of 64.3%, 5-year survival rate of 50%. PRCC was a distinct malignant entity with unique pathological features. The prognosis of PRCC was worse than that of chromophobe renal cell carcinoma.

    ABSTRACT: To assess the utility of P504S immunohistochemistry in the diagnosis and differential diagnosis of prostatic adenocarcinoma. Light microscopy and immunohistochemistry examinations (EnVision staining) were performed in 117 cases of prostatic adenocarcinoma, PIN, AAH, ASAP, BPH and normal prostatic tissue to correlate the morphology and protein expression of P504S, 34betaE12, and P63. Seventy-one of the 78 (91%) cases of prostatic adenocarcinoma stained positive for P504S, with strong cytoplasmic granular staining in most cases, and a weak or intense granular staining along the circumferential luminal and apical cell border membrane in a few cases. Negative P504S immunostaining was observed in 7 of 78 (9%) cases of prostatic adenocarcinoma, all of which were clear cell type prostatic adenocarcinoma. Cases of PIN (9 cases), AAH (6 cases) and ASAP (2 cases) showed various expression levels of P504S. Sixty-five of 68 (96%) cases of normal prostates and BPH were negative for P504S and basal cell hyperplasia cases were also negative. P504S is a useful marker for microscopic diagnosis of prostatic adenocarcinoma, and immunohistochemistry study using a combination of P504S and 34betaE12/p63 may be of greater benefit in aiding the differential diagnoses.
