Pigmented basal cell carcinoma

Pigmented Basal Cell Carcinoma is a variant of Basal Cell Carcinoma, a common form of skin cancer. It is characterized by its dark coloration, which is due to the presence of melanin, a pigment found in the skin.

Overview

Pigmented Basal Cell Carcinoma (PBCC) is a subtype of Basal Cell Carcinoma (BCC), the most common form of skin cancer. BCCs are cancers that arise from the basal cells, which are found in the lowest layer of the epidermis. PBCC is characterized by its dark color, which is due to the presence of melanin in the tumor cells.

Symptoms

The primary symptom of PBCC is the appearance of a dark, shiny bump on the skin. This bump may be black, brown, or blue in color. Other symptoms may include a change in the size, shape, or color of a mole, a sore that does not heal, or a patch of skin that is red, irritated, or swollen.

Causes

The exact cause of PBCC is unknown, but it is thought to be related to long-term exposure to ultraviolet (UV) radiation, either from the sun or from tanning beds. Other risk factors may include a family history of skin cancer, a history of sunburns, fair skin, and a weakened immune system.

Diagnosis

PBCC is typically diagnosed through a biopsy, in which a small sample of the suspicious skin is removed and examined under a microscope. The presence of melanin in the tumor cells is a key indicator of PBCC.

Treatment

Treatment for PBCC typically involves surgical removal of the tumor. Other treatment options may include radiation therapy, cryotherapy (freezing the cancer cells), or topical medications.

Prognosis

The prognosis for PBCC is generally good, as it is usually slow-growing and rarely spreads to other parts of the body. However, if left untreated, it can cause significant skin damage and disfigurement.
