Malerbe Epithelioma Skin

Malerba skin epithelioma is a rare benign skin tumor belonging to the group of epithelial tumors.

The name of the tumor comes from the name of the French dermatologist Louis-Charles Malherbe, who first described this disease in 1889.

Malherba epithelioma is a slowly growing nodule in the dermis, usually located on the face or upper extremities. The size of the tumor usually does not exceed 1-3 cm. Its color can vary from yellowish to brown. The consistency is dense, sometimes with areas of ossification.

Histologically, malerba epithelioma consists of cells of the basal layer of the epidermis, forming solid clusters and cords. Characterized by severe dyskeratosis - accumulation of horny substance in tumor cells.

Treatment for malerba epithelioma involves complete surgical excision. The prognosis is favorable; relapses after adequate treatment are not common.

Malherbe epithelioma - (a. Malherbe, 1845-1915, French Doctor; syn. epithelioma ncrotizing, epithelial common) Malherbe is an oncological epidermoepithelial tumor, characterized by the possibility of ulceration and the presence of areas of necrosis, as well as calcification of the deepest layers (recurrent) sometimes even affecting the cartilage of the nose, perichondrium, and laryngeal cartilage. In the world literature it is found under the names: epithelioma (later), melanoform epithelioma, coin-shaped epithelioma and some others. Among patients who have undergone surgical treatment, relapse of the disease usually occurs within the next 5-8 years. This disease in our country is most often found in women under the age of 30 and is most often localized on the skin of the back of the nose.
