Eccrine porocarcinoma: a case report

Porocarcinoma; presentation and management, a meta-analysis of 453 cases

BACKGROUND

porocarcinoma is a rare sort of skin cancer developing from sweat glands. Its clinical course and management are not well understood.

OBJECTIVES

the current meta-analysis is to address the presentation and management of porocarcinoma.

DATA SOURCES

Web of Science, PubMed, MEDLINE on OVID and Google scholar were searched for English-language studies published before December 1, 2016.

RESULTS

The review of literature revealed 453 cases. From which 222 (49%) cases were male and female were 231 (51%). The mean age was 67.57 years. The mean duration of presentation was 5.57 years ranging from 4 days to 60 years of age. The most common site of affection is the head and neck (39.9%) followed by lower extremity (33.9%). Mass and nodule are the most common modes of presentation. Metastasis occurred at presentation in 110 (31%) cases. The most common organ to which porocarcinoma metastizes is the nearby lymph node (57.7%).

Eccrine Porocarcinoma of the Scalp: A Rare Case Report with Review of Literature

Eccrine porocarcinoma (EPC) is a potentially lethal neoplasm of the skin that arises from the intraepidermal portion of the eccrine sweat glands. It was previously known as eccrine adenocarcinoma or malignant eccrine poroma. It commonly occurs between 60 to 80 years of age, usually arising from hands and feet. However, few case reports on involvement of rare sites such as scalp, face and eyelids are present in literature. We herein report an unusual case of porocarcinoma arising on the right parieto occipital region of scalp in a 29-year-old young female patient. To the best of our knowledge, there have been fewer than 20 cases of porocarcinoma arising on scalp with fewer than 10 cases seen in younger age group reported previously in the literature.
