男性乳腺少见疾病的数字钼靶X线及临床分析

目的：提高对男性乳腺少见疾病的 X 线影像表现和临床特征的认识。方法收集手术病理证实的12例男性乳腺少见疾病患者的全部资料,分析其数字钼靶 X 线征象及临床特征。结果(1)术后病理：脂性肉芽肿1例,浆细胞性乳腺炎2例,表皮囊肿继发感染1例,导管内乳头状瘤1例,乳腺癌6例(浸润性导管癌4例,低分化腺癌1例,黏液腺癌1例),非霍奇金淋巴瘤1例。(2)数字钼靶 X 线摄影表现为乳房内单发肿块11例,多发者1例,10例肿物位于乳晕后方,2例远离乳头方向,肿物边缘模糊者9例,毛刺征1例、分叶征1例、伴微钙化1例,无单纯微钙化者,10例伴有乳头内陷和乳晕区皮肤增厚,1例伴有腋前淋巴结肿大。(3)本组 X 线诊断符合率41%(5/12),其中男性乳腺癌的诊断符合率最高(83.3%)；总误诊率为59%(7/12),其中良性病变误诊率高达80%(4/5)。结论男性乳腺少见疾病发病率低且病种繁杂,良恶性病变的 X 线征象及临床表现无特异性,误诊率较高。

Analysis of digital mammography and clinical manifestations of rare diseases in male breast

Objective To probe the X-ray imaging features and clinical manifestations of some rare diseases in male breast.Methods The data of 12 patients with some rare diseases in male breast were collected.The X-ray manifestations and clinical features of the diseases were analyzed.Results The postoperative pathology showed the lipogranuloma in 1 patient,plasma cell mastitis in 2,secondary infection of epidermal cyst in 1,intraductal papilloma in 1,breast cancer in 6 (invasive ductal carcinoma in 4,poor-differentiated adenocarcinoma in 1,and mucinous carcinoma in 1),and breast lymphoma in 1.The digital mammography showed the intramammary solitary masses in 1 1 and multiple ones in 1.10 masses were located at the rear of the areola,and other 2 were opposite.Unclear edge of the lesion was found in 9,spiculation in 1,lobulation in 1,and micro-calcification in 1.Nipple retraction and areola skin thickening in 10 and enlarged axillary lymph node in 1 were also found.The total accurate rate of X-ray diagnosis was 41% (5/12),while that of breast cancer was 83.3%.The total misdiagnosis rate was 59% (7/12),and that of benign lesion was 80% (4/5).Conclusion The diseases in male breast are rare and various,and the X-ray and clinical manifestations are not specific.
