Abstract

Primary malignant melanoma in breast parenchyma (PMB) is an extremely rare disease, and the most common presentation is a palpable breast lump. To the best of our knowledge, a case of PMB presenting as a breast abscess has not been reported in English literatures. We present a case of PMB that manifested as a recurrent breast abscess in a 71-year-old woman. On MRI, an enhancing solid mass with a cystic or necrotic portion was revealed with some high signal intensities on precontrast-enhanced T1-weighted images and a dark rim on T2-weighed images. The MRI features played a pivotal role in identifying the underlying malignant condition and making an accurate diagnosis of this rare case of PMB with unusual clinical presentation.

유방 실질의 원발성 악성 흑색종은 극히 드물며, 대부분 유방 내 만져지는 종괴로 나타난다. 유방 농양으로 나타난 원발성 악성 흑색종은 아직까지 영문 문헌에 보고된 바 없다. 저자들은 반복적으로 재발하는 유방 농양이 있었던 71세 여자 환자에서 진단된 유방 실질의 원발성 악성 흑색종을 보고하고자 한다. 유방 자기공명영상 검사에서 조영증강되는 고형 부분과 낭성 또는 괴사 부분을 동반한 종괴가 있었고, 조영 전 T1 강조 영상에서 높은 신호 강도인 부분과 T2 강조 영상에서 어두운 신호 강도인 테두리가 있었다. 재발성 유방 농양의 임상 소견을 보인 본 증례에서 기저의 악성 질환 가능성을 의심하고 정확한 진단을 얻는 데 MRI 소견이 결정적인 역할을 하였다.
