Cellular schwannoma of the retroperitoneum with cystic degeneration, mimicking an ovarian cyst, with CKAE1/AE3 and desmin expression.

2014

Schwannoma is an encapsulated benign tumour usually presenting as a solitary mass on the flexor surfaces of the extremities, neck, mediastinum, posterior spinal roots and cerebellopontine angle, an...

Immunohistochemical expression and distribution of orexin, orphanin and leptin in the major salivary glands of some mammals

2012

Abstract: The aim of the study was to assess the involvement of apoptotic factors, cytokeratins and metalloproteinase- 9 in the histogenesis of both Epithelialized Gingival Lesions (EGL) and Periapical Lesions (PAL). 55 consecutive patients, 30 with PAL and 25 with EGL, were selected for the study after clinical and radiological examinations. The PAL patients had severe periapical lesions and tooth decay with exposure of the pulp chamber. All PAL and EGL biopsies were surgically extracted, fixed in 10% buffered formalin, and processed for routine light microscopy. Ten biopsies of each category were processed for immunohistochemistry (IHC). Serial paraffin sections were stained by IHC with a…

Sarcomatoid carcinoma of urinary bladder: Immunohistochemical study of an uncommon case

2002

A case of sarcomatoid carcinoma of the bladder is reported herein. Immunohistochemical staining with human pancytokeratin antibody was negative, while vimentin staining was strongly positive, suggesting a diagnosis of sarcoma of the bladder. Further immunohistochemical analysis revealed positivity for AE1/AE3 cytokeratins, permitting a correct diagnosis of sarcomatoid carcinoma of the bladder. It can be difficult to distinguish between sarcomatoid carcinoma, undifferentiated carcinoma and sarcoma, particularly if the biopsy specimens are of small size. In rare cases, sarcomatoid tumors may express epithelial markers different from those revealed by human pancytokeratin staining. Copyright ©…
