Disseminated histoplasmosis in an immunocompetent haweli dweller: A diagnosis and follow-up by endoscopic ultrasound-guided fine-needle aspiration.

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is nowadays widespread minimally invasive procedure for diagnosing a large number of benign as well as malignant lesions. We report a case of a 62-year-old immunocompetent elderly male, who presented with high-grade fever, hepatosplenomegaly and mediastinal and intra-abdominal lymph nodes. He was residing in an old haweli with bats infestation. EUS-FNA of the subcarinal and the preaortic lymph node clinched the diagnosis. A rapid on-site evaluation of the cytology material revealed organisms conforming to the morphology of Histoplasma capsulatum. The patient was immediately started on amphotericin B and itraconazole and responded well. In this case, we found the role of EUS-FNA not only in diagnosis, but also in the follow-up of the patient.
