초록

52세 남자 환자가 우측 유방의 바깥부위에서 무통의 단단한 종괴를 호소하였다. 흉부 CT에서 3.3 cm 크기의 원형의 미세소엽상 경계의 조영증강되는 종괴가 확인되었고, 초음파에서는 미세소엽상 경계를 보이는 저에코성 종괴로, 종괴의 내부에는 석회화와 혈류가 보였다. 중심부바늘생검에서 종괴는 양성 과립세포종양(granular cell tumor; 이하 GCT)으로 확진되었다. 환자는 타병원으로 전원되어 병변의 수술적 제거를 시행하였다. 과립세포종양은 슈반세포(schwann cell)에 유래하는 종양으로, 유방에서는 드물고 대부분은 양성이다. 과립세포종양의 임상적 및 방사선학적 특징은 악성 종양과 유사한 소견을 보여 감별이 어려운 경우가 있으며, CT 영상은 거의 보고된 바가 없다. 본 증례를 통해 임상의와 방사선 전문의가 드물지만 양성종양인 GCT의 영상의학적 특징을 알고, 이를 악성종양과 감별하여 과도한 치료를 피해야 할것이다.

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.
