Porphyria cutanea tarda and human immunodeficiency virus: two cases associated with hepatitis C.
Hepatitis C virus (HCV) was recently recognized as a probable etiologic factor for porphyria cutanea tarda (PCT). A review of the literature revealed 40 cases of PCT associated with the human immunodeficiency virus (HIV). In most of these cases, hepatitis C status was unknown. We describe two patients with PCT who were coinfected with HIV and HCV and discuss the interaction of these two viruses. A diagnosis of PCT, especially in a young patient, should prompt investigation for underlying HIV and HCV infection. Porphyrin studies should be performed in any patient with HIV and photosensitivity. Clinicians should be aware of the infectious risk associated with the vesicles and erosions in these patients.
