Abstract

Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare, benign soft tissue tumor with uncertain pathogenesis and lineage most commonly found in the lower and upper extremities. No reports exist of this tumor metastasizing, though local recurrence is common. To date, only approximately 100 cases have been reported. We present the case of a patient presenting with hoarseness and dyspnea found to have PHAT of the larynx, a location previously unreported in the literature and requiring unique management considerations.

Keywords: Larynx; Pleomorphic hyalinizing angiectatic tumor.
