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 ...

OBJECTIVE Eccrine porocarcinoma is a rare malignant tumor of eccrine sweat glands. It may arise de novo, but it usually develops in pre-existing eccrine poroma. Here we report a case of eccrine porocarcinoma in the grafted area on the scalp of a male patient who had recurrent basal cell carcinoma of the scalp, with clinical, histopathological and, immunohistochemical features. CASE We report ...

Eccrine poroma is a benign adnexal neoplasm that clinically may mimic malignant skin tumors such as squamous cell carcinoma and amelanotic melanoma. The dermoscopic features of pigmented and nonpigmented eccrine poroma have recently been described. We present 2 cases of eccrine poroma, with their dermoscopic features. The lesions were characterized by multiple red lacunes and a polymorphous vas...

Editor Congenital eccrine naevus is a rare clinical entity. Fewer than 20 cases had been reported, and only three cases were congenital. 1,2 We present a child with congenital localized hyperhidrosis on the forearm. To the best of our knowledge, this is the first congenital eccrine naevus successfully treated with botulinum toxin type A. A 12-year-old girl with no significant past medical histo...

Sir, Porokeratotic eccrine ostial and dermal duct naevus (PEODDN) is a rare disorder of keratinization with eccrine involvement that histologically presents a cornoid lamella exclusively associated with eccrine ostia and the underlying sweat ducts (1). It is an expression of genetic mosaicism (2) and is characterized by asymptomatic grouped keratotic papules and plaques with a linear distributi...

Eccrine angiomatous hamartoma (EAH) is a rare benign disease that is characterized by an abnormal proliferation of eccrine glands and vascular elements. It is generally congenital, but it can appear before puberty. It usually presents as a single plaque or nodule, but multiple patch-like lesions are also possible. EAH is mostly asymptomatic, but it is sometimes associated with pain or hyperhidr...

Eccrine spiradenomas are uncommon, benign lesions, which are thought to originate from the eccrine sweat glands. They are common in young adults and are without a sex predilection. Here we report a case of eccrine spiradenoma of the breast skin in a 39-year-old woman who presented with a breast nodule for 10 years. It is crucial to take eccrine spiradenoma into consideration in superficial, wel...

A case of eccrine porocarcinoma with Bowenoid changes is reported. We compared the results of immunohistochemical staining for epithelial membrane antigen in the present case with results in Bowen's disease to determine whether the presence of epithelial membrane antigen (EMA) enabled us to differentiate between Bowen's disease and eccrine porocarcinoma with Bowenoid changes. Histologically, th...

Comedo-like lesions of the palm, present since birth, are studied electronmicroscopically and their eccrine nature demonstrated. We suggest their inclusion under the name porokeratotic eccrine-ostial and dermal duct nevus previously proposed by Abell and Read.

INTRODUCTION Cutaneous appendageal tumor can differentiate towards or arise from either pilosebaceous apparatus or the eccrine sweat glands. Appendageal tumors are relatively rare, their clinical appearance is non-specific, and the vast majority are not diagnosed until after excision. Eccrine porocarcinoma (EP), also known as malignant eccrine poroma is a rare adnexal tumor arising from the int...
