[Eccrine carcinoma: a diagnostic pitfall].

Background: The eccrine carcinoma is a rare form of skin adnexal malignancy, usually presenting as a locally invasive, solitary lesion in the head and neck region. Histopathologically and immunohistochemically, eccrine carcinomas are difficult to differentiate from cutaneous metastases of breast carcinomas. Unlike treatment of cutaneous metastasis, treatment of a solitary eccrine carcinoma entails excision, generally without systematic therapy.

Thermal artifacts in bladder tumors following loop endoresection: electrovaporization v electrocauterization.

Background And Purpose: Recently, the electrovaporization (EV) technique has been used for loop endoresection of bladder tumors. Our objective was to evaluate whether bladder tumors resected by EV with a loop wire are fit for histologic diagnosis. In addition, a quantitative comparison was made with the thermal artifacts created with a standard electrocautery (EC) loop resection.
