Disseminated histoplasmosis in a patient with chronic lymphoedema

A 54 year-old man with lymphopenia secondary to lymphatic filariasis was admitted with dry cough, fever and wasting syndrome. He was diagnosed with sarcoidosis and therapy with corticosteroid was initiated. The patient evolved with worsening of the symptoms. Histoplasma species was recovered in lung biopsy tissue, lung tissue culture, and bone marrow aspirate. The authors describe the first case of disseminated histoplasmosis secondary to lymphatic filariasis, followed by a literature review. 2012 Elsevier Ltd. All rights reserved.

Fever of unknown origin

Fever of unknown origin (FUO) remains a challenging clinical problem despite recent advances in diagnostic tools and techniques. Because primary care physicians are often the first ones to encounter a case of FUO, it is important that they be familiar with the best strategy and steps for confronting this problem initially. Here, Drs Amin and Kauffman review the major causes of FUO in adults and describe an in-depth approach to laboratory and radiologic tests that help establish a diagnosis.

Histoplasmosis

The diagnosis of histoplasmosis depends on recognition of the different clinical manifestations of infection, accompanied by knowledge of the accuracy and limitations of tests used for diagnosis of fungal infections. Although most infections are asymptomatic, histoplasmosis can be severe, or even fatal, in patients who have experienced a heavy exposure, have underlying immune defects, or develop progressive disease that is not recognized and treated. This article provides an up-to-date clinical review of histoplasmosis, focusing on recognition, diagnosis, and management.
