[Clinicopathologic features of granulocytic sarcoma: a study of 38 cases].

Objective: To study the clinicopathologic features of granulocytic sarcoma.

Methods: The clinical and pathologic findings of 38 cases of granulocytic sarcoma were retrospectively analyzed. Immunohistochemical study was performed and the literature was reviewed.

[Clinicopathological study of 5 cases of proximal-type epithelioid sarcoma].

Objective: To investigate the clinicopathological characteristics, diagnosis and differential diagnoses of proximal-type epithelioid sarcoma (PES).

Methods: Five cases of PES were retrieved from pathology files. Clinical, pathologic and immunohistochemical features of the tumors were reviewed.

[Renal cell carcinoma associated with Xp11.2 translocations/TFE3 gene fusions: a study of 11 cases and review of literature].

Objective: To study the clinicopathologic features, differential diagnosis and prognosis of renal cell carcinoma associated with Xp11.2 translocations/TFE3 gene fusions.

Methods: The histopathologic findings and immunophenotype of 11 cases of renal cell carcinoma associated with Xp11.

[Clinicopathologic study of renal cell carcinoma with rhabdoid features].

Objective: To study the clinicopathologic features and biologic behavior of renal cell carcinoma (RCC) with rhabdoid features.

Methods: Ten cases of RCC with rhabdoid features collected during the period from 1995 to 2005 were enrolled into the study. The clinical findings were analyzed and the hematoxylin and eosin-stained sections were reviewed.

[Expression of Ksp-cadherin in renal epithelial neoplasm and its clinicopathologic significance].

Objective: To study the expression of a novel marker, kidney-specific-protein (Ksp)-cadherin, in renal epithelial neoplasms and its clinicopathologic significance.

Methods: Immunohistochemical study (using EnVision method) for Ksp-cadherin, CD10, vimentin, epithelial membrane antigen and CK7 was carried out in normal human kidney samples, as well as in 166 cases of primary renal neoplasms (including 120 cases of clear cell renal cell carcinoma (RCC), 20 cases of papillary RCC (type I papillary RCC 15 cases and type II papillary RCC 5 cases), 18 cases of chromophobe RCC and 8 cases of oncocytoma).

Results: Ksp-cadherin was expressed in distal convoluted tubules of normal kidney in a membranous pattern.
