Introduction. Porocarcinoma is a rare sort of skin cancer developing from sweat glands, specifically, it is a malignancy of the eccrine sweat glands [1]. Its etiology is not well understood. However, some studies have showed that the tumor developed from a pre-existing eccrine poroma.
What is cancer of the sweat glands called?
Syringomatous carcinoma (SC) has many variants or synonyms, including syringoid eccrine carcinoma (sometimes called eccrine SC), eccrine epithelioma (a basal cell tumor with eccrine differentiation), sweat-gland carcinoma with syringomatous features, and malignant syringoma microcystic adnexal carcinoma.
Do Poromas need to be excised?
The diagnosis and treatment of poromas is typically performed via simple complete excision.
What is the meaning of poroma?
A poroma is a benign skin tumor derived from sweat glands. Although the original term poroma was initially used to describe a tumor derived from the ductal epithelium of eccrine sweat glands, the term is used in general reference to tumors derived from ductal portions of both eccrine and apocrine sweat glands.
What is nodular Hidradenoma?
Nodular hidradenoma (NH) is a benign adnexal tumor that arises from either eccrine or apocrine sweat glands. NH can originate from any cutaneous site, but the most common sites are the head and anterior surface of the trunk, with very rare cases in the extremities.
Is sweat gland carcinoma cancerous?
Sweat gland carcinomas are rare cancers with a poor prognosis often presenting as histological surprises. Surgery in the form of wide local excision and lymph node dissection is the mainstay of treatment.
What causes sweat gland cancer?
Very few cancers have a single known cause. Most seem to be caused by a complex mix of risk factors, some environmental and some genetic or hereditary. In the case of sweat gland, hair follicle, or sebaceous gland tumors, there is no known cause.
What causes eccrine poroma and how is it treated?
The exact cause of this tumor is not known but it is believed to be caused as a result of genetic mutation. It is a solitary flesh colored tumor which sometimes is painful. Eccrine poroma does not need any treatment.
What are the treatment options for electeccrine poromas?
Eccrine poromas can be treated by excision, shave and diathermy, cryotherapy and CO2 laser (Deckelbaum et al 2014, Sawaya & Khachemoune 2014). SAUL SUSTER, MARTIN C. MIHMJR., in Modern Surgical Pathology (Second Edition), 2009
What is the prognosis of eccrine porocarcinoma?
Surgical excision with histologically clear margins is the optimal management for eccrine poroma undergoing recent changes, as an incisional biopsy may appear falsely benign 13). In early eccrine porocarcinoma lesions, cure is possible in up to 70-80% of patients, although a high recurrence rate of up to 20% has been reported 14).
What is an eccrine lesion?
Eccrine Poroma An eccrine poroma is a benign lesion derived from a portion of the sweat gland duct called the acrosyringium. There is a malignant eccrine poroma (also known as porocarcinoma), which is a rare tumour.
