title: The utility of fine needle aspiration for diagnosis of extrapulmonary coccidioidomycosis: a case report and discussion.
abstract: Coccidioidomycosis typically presents as pneumonia, but rarely manifests as extrapulmonary disease. We describe a case of coccidioidal infection that presented as a neck mass and was diagnosed by fine needle aspiration (FNA). Initial clinical suspicion was for mycobacterial infection. Several modalities are available for the detection of Coccidioides species, but culture has been the mainstay of diagnosis. FNA provides a relatively noninvasive and effective modality for tissue-based diagnosis based on characteristic histological findings. It allows the additional advantage of early on-site identification, allowing for triage of the specimen, notification of laboratory staff and prompt initiation of treatment. The case herein described is intended to demonstrate an atypical presentation of extrapulmonary coccidioidomycosis and highlight the utility of FNA for diagnosis of such lesions. Clinicians should be aware of the unique advantages of FNA for evaluation of lesions of infectious etiology.
