Abstract: Skin is the largest organ of the body and it is direct contact with external environment so many infectious agents invade the skin and causes much disease. Lupus vulgaris is the most common form of cutaneous tuberculosis in adults. A chronic, progressive, post-primary, paucibacillary form of cutaneous tuberculosis, occurring in a person with a moderate or high degree of immunity. The characteristic lesion is a plaque, composed of soft, reddish-brown papules, the appearance on diascopy being said to resemble apple jelly. Lupus vulgaris originates from an underlying focus of tuberculosis, typically in a bone, joint or lymph node, and arises by either contiguous extension of the disease from underlying affected tissue or by haematogenous or lymphatic spread. Sometimes the underlying focus is not clinically apparent, and in such cases reactivation of a latent cutaneous focus secondary to previous silent bacteraemia is postulated. Microscopically it is characterized by tubercles with scanty or absent central caseation, surrounded by epithelioid histiocytes and multinucleate giant cells, which are present in the superficial dermis with prominent peripheral lymphocytes.
We reported a case of lupus vulgaris in a 22 year old female who presented with single plaque at elbow. Histopathological features of skin biopsy from plaque shows multiple non caseating granuloma suggestive of lupus vulgaris.
