Disfiguring lupus vulgaris (lat. Lupus vulgaris mutilans) is a rare type of cutaneous tuberculosis caused by Mycobacterium tuberculosis. It is characterized by the appearance of painless nodules and tubercles on the skin, which increase in size over time, merge and form infiltrates.
The disease most often affects exposed areas of the skin - the face, hands, and forearms. Gradually, the foci of inflammation increase and spread to the underlying tissues, which leads to disfigurement and deformation of the affected areas. Characterized by deep ulcerations and cicatricial changes.
Treatment of disfiguring lupus vulgaris includes the administration of anti-tuberculosis drugs. In severe cases, surgery may be required. The prognosis depends on timely diagnosis and proper treatment. In advanced forms, disfigurement is possible.
