Poncet's disease and papulonecrotic tuberculid in a patient infected with the human immunodeficiency virus.
We report the case of a 27-year-old patient with the human immunodeficiency virus (HIV) infection who presented with a 2-week history of crops of painful, red papules over the trunk and extremities, together with a sterile, symmetric polyarthritis involving the small and large joints. Histologic study of a skin biopsy specimen demonstrated features of papulonecrotic tuberculid. Analytical and microbiologic studies ruled out tuberculous infection. Both the synovial and the skin processes were considered to be an immune response secondary to Mycobacterium tuberculosis infection. Specific treatment was established, and there was marked improvement in both the skin and joint symptoms. This case illustrates the complex relationship between the host and the HIV, suggesting an immune dysregulation cause for both the synovial and the skin lesions.
