Abstract
|
|
|
|
Nasal angiomyolipomas are exceedingly rare and usually present as small tumors in middleaged or old men. Their histology is similar to that of the renal counterpart, but they differ in the absence of epithelioid cells, the lack of HMB-45 immunoexpression and no association with tuberous sclerosis. A case of angiomyolipoma occurring in the right nasal cavity was presented in a 44-year-old male patient. The mass was removed by an endoscopic approach. A well-circumscribed, 1.3 cm-sized, ovoid mass was composed of yellowish gray, solid, soft tissue. Histologically, it consisted of bundles of smooth muscles, mature fat cells and thick-walled blood vessels. Nests of seromucous glands were admixed within the mass. Neither epithelioid nor pleomorphic cells were found, and HMB-45-positive cells were not detected. No recurrence has been detected for 2 months after the operation.
