BACKGROUND Malignant tumors arising from the vulva account for only 0.6 % of all cancers in female patients. The predominant histologic type, representing about 90 % of these malignancies, is squamous cell carcinoma. Eccrine porocarcinoma is a rare malignant tumor arising from sweat glands. The incidence of eccrine porocarcinoma is estimated at 0.005-0.01 % of all cutaneous tumors. To the best ...

Sweat gland carcinomas are rare skin tumors that typically occur in older patients. The spectrum of their clinical and pathologic features is broad, and many different types of sweat gland carcinomas have been described, ranging from fairly indolent to highly aggressive neoplasms. We present two cases of sweat gland carcinoma with a predominant small cell morphology. Both tumors occurred in chi...

TO THE EDITOR: All published comparisons of local sweat sampling techniques (e.g., filter paper, gauze, skin scraping, pipette, rubber glove, or arm bag collections) versus the whole body wash down method have reported that local samples contained higher electrolyte concentrations (4). The present paper by Weschler (5) provides a hypothetical mechanism for these findings [i.e., sweat leaches el...

Background: Microcystic adnexal tumor is a rare sclerosing variant of ductal carcinoma of eccrine sweat glands which is highly invasive. This tumor is often misdiagnosed as other benign or malignant skin lesions and improper treatment is carried on and is associated with high recurrence rate. Case presen...

BACKGROUND Eccrine porocarcinoma is an uncommon neoplasm of the intra-epidermal sweat gland duct. PATIENTS AND METHODS A case of eccrine porocarcinoma in a female renal transplant patient aged 45 years is described with a review of pertinent literature. RESULTS The primary tumour was highly pleomorphic. In places large and small cells merged and focally the former component infiltrated the ...

Eccrine porocarcinoma (EPC) is a rare malignant tumour of sweat gland origin representing only 0.005-0.01% of epithelial cutaneous neoplasms. EPC is an unusual tumour to diagnose both clinically and histologically. Several reports describe aggressive behaviour. Due to its rarity, specific guidelines for management are not readily available. We report a series of four cases of EPC analysed in te...

We present a case of sclerosing syringoid carcinoma of the finger, a type of eccrine sweat duct malignancy that is rare and mimics the appearance of a benign lesion, but is locally aggressive and has a tendency to recur. It has seldom been reported in the literature. It has a predilection for the head and neck region but is rare in the extremities. We believe this is the second reported case of...
