A Case of Nasal Angiomyolipoma in Young Man / 대한이비인후과학회지

ABSTRACT

Angiomyolipoma is a benign tumor that is composed of adipose tissue, blood vessels and smooth muscle. The kidney is the most common site for this tumor. Although extrarenal angiomyolipoma is rarely found in areas other than the kidney, it has been observed in other organs such as liver, heart, mediastinum, spermatic cord, vaginal wall, oral cavity, and so on. Angiomyolipoma in the nasal cavity especially, has been very rarely reported in literature. Furthermore, nasal angiomyolipoma is mostly found in middle aged or old men. In this case, angiomyolipoma was found in a 29-year-old male patient who was the youngest of the reported cases. He complained of nasal obstruction and physical examination revealed a 1.5 cm sized mass in the left posterior part of the nasal septum. The mass was composed of an intimate mixture of mature fat, smooth muscle cells, and thick walled varying sized blood vessels histopathologically coinciding with angiomyolipoma. It was removed via endoscopic surgery without complications.
