Isolated nodular cutaneous histoplasmosis. The initial manifestation of recurrent disseminated disease

Cutaneous manifestations of histoplasmosis may be divided into primary and secondary lesions. Primary cutaneous histoplasmosis is rare; to our knowledge, there are only three reported cases in the literature. Secondary cutaneous histoplasmosis develops during the course of disseminated disease. An isolated nodule of the hand was the initially appearing sign of recurrent disseminated disease in our patient. Because of the extreme rarity of primary cutaneous histoplasmosis, cutaneous lesions that are proven to be due to histoplasmosis should alert the physician to the presence of disseminated disease.
