ABSTRACT
Angiofibroma is benign hypervascular tumor that usually occurs in the nasopharynx of adolescent male patient and rarely originates from outside of the nasopharynx, called extranasopharyngeal angiofibroma. The clinical and radiologic findings of extranasopharyngeal angiofibroma are similar to other hypervascular tumors, which may delay diagnosis and treatment. We present a case of extranasopharyngeal angiofibroma arising from nasal septum of a 43-year-old male who complained of right nasal obstruction. Contrast enhancement CT revealed a hypervascular tumor of the nasal septum and the tumor was removed by endoscopic resection. Histopathologic examination confirmed the diagnosis of angiofibroma.
ABSTRACT
A 52-year-old male complained of a painless, firm, and slow-growing mass in his right breast outer portion. The chest CT revealed a 3.3 cm-sized oval shaped, microlobulated, mild enhancing mass. Ultrasound showed a microlobulated marginated heterogeneous hypoechoic mass with internal vascularity and calcifications in the mass. On the ultrasound-guided core needle biopsy, the mass was confirmed as a benign granular cell tumor (GCT). The patient transferred to another hospital and underwent surgical removal of the lesion. GCT of the breast is uncommon and mostly benign neoplasm to originate from Schwann cell. Clinical and radiologic features of GCTs, including CT and ultrasound images, mimic malignancy and make diagnosis of GCT more difficult. The CT images of GCTs are much rarely reported. Physicians and radiologists must be aware of radiologic characteristics of this rare benign tumor for male breast, to avoid misdiagnosis this tumor for breast malignancy and overtreat.
