Mastocytosis Eruptive Erythematous-Spotty

Mastocytoma is a rare benign skin condition that occurs due to an increase in the number of special cells called mast cells. These cells contain protein granules that, when irritated, can cause redness and swelling of the skin. Although most patients have never experienced any health problems, some people may experience pain and itching at the site of the mast cell.

Mast cells are divided into two main types: telangiectic and non-telangiectic. Telangietic mast cells are the most common form of tumor that develops from telangia (red blood cell extensions) on the skin. A symmetrical distribution of light red to pinkish-purple spots appears on the skin ranging in size from one centimeter to several centimeters, sometimes up to five centimeters. The spots are slightly flaky and look like freckles. Symptoms may include itching and sun sensitivity. If the disease is not treated, the skin in the affected areas may become darker and rougher, and malignant tumors may form. Typically, swelling appears on sun-exposed areas of the body, such as the face, neck, arms and legs. In some cases, problems with vision or hearing may also occur.

Treatment for mast cells depends on the severity of the disease and the presence of additional symptoms. Some patients choose to use creams to treat localized disease, while others may receive therapeutic doses of topical or systemic medications to treat systemic disease. Surgical removal of the tumor or photochemotherapy may also be performed.
