Lung and lupus vulgaris.

Lupus vulgaris is chronic, postprimary, paucibacillary cutaneous tuberculosis found in individuals with moderate immunity and high degree of tuberculin sensitivity. Eighty percent of the lesions are on the head and neck. We present the case of a 38 year old lady who was admitted with complaints of worsening breathlessness and low grade fever of one month duration. Examination showed multiple, nontender skin ulcers on bilateral lumbar areas, two oozing serosanguinous discharge and others scarred in the centre. Respiratory system examination and chest X-ray revealed right sided pleural effusion. On investigation, pleural fluid was tuberculous in nature. Skin biopsy from the edge of ulcer was also suggestive of tuberculosis. Patient is doing well on antituberculous drugs. This case highlights the importance of cutaneous manifestations of systemic disease and is an example of the unusual presentation of lupus vulgaris in a case of pleural effusion.
