Legionnaires' disease arising with hirsutism: case report of an extremely confusing event.

BACKGROUND: Legionella bacteria is a common cause of pneumonia, but the infection may affect several organs in the most serious cases. A systemic involvement ab initio could be non-specific, leading to a diagnostic misinterpretation. CASE PRESENTATION: A 33-year-old woman had been complaining of mental confusion, restlessness, aggressiveness, and, subsequently, hirsutism. After 3 weeks, the patient developed pneumonia and died during the hospitalization. The autopsy examination revealed a multi-organ necrotizing exudative disease involving the lung, the heart and the brain. The microbiological tests of tracheal aspirate were positive for Legionella pneumophila serotype 1. CONCLUSION: The Legionella infection may show a proteiform clinical course and an extra-pulmonary manifestation may be the first sign of the disease. Herein, we report a case of Legionella infection in a young female, presenting with non-specific neurological symptoms and hirsutism at onset, misdiagnosed as a metabolic disease.

Paracoccidioidomycosis in a woman with idiopathic hirsutism.

Paracoccidioidomycosis, especially the chronic pulmonary form of the disease, is not commonly described in females. Data from in vitro and vivo studies support the hypothesis that estrogens might influence the pathogenesis of paracoccidioidomycosis in humans by inhibition of transition of conidia or mycelia to yeast form of Paracoccidioides brasiliensis. The authors describe a chronic progressive pulmonary form of paracoccidioidomycosis in a woman with idiopathic hirsutism. In addition to estrogens, the present report suggests that other hormonal factors might play an important role in the pathogenesis of paracoccidioidomycosis, including the increased production of 5alpha-dehydrotestosterone frequently described in individuals with idiopathic hirsutism.
