Angiolymphoid Hyperplasia with Eosinophilia in a Patient With Coccidioidomycosis.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare nodular mass that has not commonly been reported in the literature in association with coccidioidomycosis (CM). Coccidioidomycosis has other known skin manifestations including erythema nodosum and interstitial granulomatous dermatitis. Pulmonary CM is the most common form of the disease and the most common cause of CM-associated rash. This is an important clinical consideration for patients with ALHE who reside in CM-endemic areas, which notably include the southwestern region of the United States, Mexico, and South America. We report the case of an ALHE lesion that resolved following treatment for CM.
