The coccidioidomycosis conundrum: a rare parotid mass.

ABSTRACT

A man, age 62 years, presented to the clinic with a 2-week history of increased nontender, nonerythematous, indurated right-sided parotid swelling. A 4 × 6-cm firm, well-circumscribed mass was palpated in the right parotid gland. A fine-needle aspiration biopsy was performed on the parotid mass with aspiration of 0.5 cc of purulent fluid with some blood. Cultures from the aspirate revealed Coccidioides immitis confirmed by DNA probe. Pathology slides revealed fungal spores. The patient was treated with 800 mg of fluconazole every day for 3 months with resolution of the parotid swelling. However, persistent cervical adenopathy remains.Although this is a rare case of acute parotid swelling, Coccidioides immitis should be considered in the differential diagnosis of parotid masses in a patient with previous coccidioidomycosis. There may be a potential for an increase in frequency and variety of atypical extrapulmonary manifestations of coccidioidomycosis that parallels the increase in coccidioidomycotic pulmonary infections. Long-term antifungal therapy appears essential for control.
