[Cutaneo-mucosal hyperpigmentation in AIDS. 4 cases]

Abstract

Four cases of pigmentation of the skin and mucous membranes in homosexuals of the IVC1 group (CDC classification) are reported. The aetiological investigation, although incomplete, pointed to a medicinal origin which could not be formally confirmed. The drugs suspected were azidothymidine, pyrimethamine and ketoconazole. There was no clinical or laboratory evidence of adrenal insufficiency. The few published cases of cutaneo-mucosal pigmentation in HIV infection, often mimicking adrenal insufficiency, emphasize the need for thorough toxicological investigation; this may avoid prescribing an unnecessary and dangerous corticosteroid therapy which might be harmful in these deeply immunocompromized patients who often have multiple infections.
