Porocarcinoma
Porocarcinoma
Porocarcinoma (pronunciation: por-o-car-cin-o-ma) is a rare type of skin cancer that originates from the sweat glands. It was first described in medical literature by Pinkus and Mehregan in 1963.
Etymology
The term "Porocarcinoma" is derived from the Greek words "poros" meaning passage or pore, and "karkinoma" meaning cancer. This refers to the cancer's origin in the sweat gland ducts.
Definition
Porocarcinoma is a malignant neoplasm that arises from the eccrine sweat glands. It is a rare form of skin cancer, accounting for less than 1% of all cutaneous malignancies. Porocarcinoma can occur anywhere on the body but is most commonly found on the lower extremities, particularly the feet.
Symptoms
The most common symptom of porocarcinoma is a slow-growing, painful nodule on the skin. The nodule may ulcerate and bleed. Other symptoms can include itching, redness, and swelling.
Diagnosis
Diagnosis of porocarcinoma is typically made through a biopsy of the affected skin. The biopsy is examined under a microscope by a pathologist who can identify the characteristic cells of porocarcinoma.
Treatment
Treatment for porocarcinoma typically involves surgical removal of the tumor. In some cases, radiation therapy or chemotherapy may be used in addition to surgery, particularly if the cancer has spread to other parts of the body.
Prognosis
The prognosis for porocarcinoma varies depending on the stage of the disease at diagnosis. Early detection and treatment can lead to a good prognosis, but the cancer can be aggressive and may spread to other parts of the body.
