Our objective was to identify the mammographic findings of breast cancer in men.
The mammograms of 23 men with proved breast cancer (mean age, 63 years; range, 44-86 years) were retrospectively reviewed. Medical histories included gynecomastia in five, prior cancer in three, and radiation exposure in two. The most common signs were a mass in 13 and bloody nipple discharge in eight.
Carcinoma was evident mammographically as an uncalcified mass in 17 patients (74%) and as a mass with microcalcifications in two patients (9%). Three tumors were not evident on mammograms, including one that was obscured by gynecomastia. Tumors were largely subareolar (14/17, 82%), and all were ductal cancers, including six pure intraductal carcinomas.
Mammograms of men with breast cancer usually show an uncalcified subareolar mass, which may mimic or be obscured by gynecomastia. If calcifications are present, they may not have a pattern usually associated with malignancy.
我们的目的是确定男性乳腺癌的乳腺X线摄影表现。
回顾性分析23例经证实患有乳腺癌男性（平均年龄63岁；范围44 - 86岁）的乳腺X线片。病史包括5例男性乳房发育症、3例既往癌症史以及2例有辐射暴露史。最常见的体征是13例有肿块，8例有乳头血性溢液。
乳腺X线摄影显示，17例患者（74%）的癌表现为非钙化肿块，2例患者（9%）表现为有微钙化的肿块。3个肿瘤在乳腺X线片上未显影，其中1个被男性乳房发育症掩盖。肿瘤大多位于乳晕下（14/17，82%），均为导管癌，包括6例单纯导管内癌。
男性乳腺癌的乳腺X线片通常显示为乳晕下非钙化肿块，可能与男性乳房发育症相似或被其掩盖。如果存在钙化，其形态可能并非通常与恶性肿瘤相关的形态。
