Multiple Pulmonary Leiomyomatous Hamartomas Associated With a Bronchogenic Cyst in a Man

Abstract

Abstract Multiple pulmonary leiomyomatous hamartomas (MPLHs) are extremely rare lesions. We present a case of MPLHs associated with a bronchogenic cyst in a symptomless, 46-year-old man. Previously, MLPHs have been reported to occur in men; therefore, not all cases of MPLHs represent metastases from a uterine smooth muscle tumor. Because these lesions represent a tumorlike overgrowth of normal tissue, we think that leiomyomatous hamartoma is an appropriate term to designate this entity. The possible influence of inflammatory cell mediators in the pathogenesis of MPLHs remains speculative.
