Oral melanotic macules in patients infected with human immunodeficiency virus.
A group of 217 patients seropositive for human immunodeficiency virus (HIV) were studied for 2 years, during which time pigmented lesions of the oral mucosa developed in 14 (6.4%) of them. The lesions were well circumscribed in some cases and diffuse in others. In some patients the macules enlarged or recurred after surgical excision. ⋯ However, the clinical behavior of these lesions appears to be different during the course of HIV infection. In some HIV-infected patients the cause of the macules might relate to the administration of zidovudine and antifungal or antibacterial drugs. In others the cause remains unknown and could be due to multiple factors.
