Male breast cancer accounts for 0.4% of all male neoplasia in Ibadan, and about 3.4% of all breast cancers in both females and males. The clinical features often presented include mass in breast, skin involvement by fixation and ulceration, sanguinous and serous discharge from the nipple. Symptoms are often delayed, the longest duration in the current series being 36 months. Geographical comparison of the histological types of male breast cancer appears to show that, while papillary carcinoma is commoner in Nigerian than in American and Danish males, on the other hand, infiltrating duct carcinoma appears much more common in the latter than in the former male races. Invasive lobular carcinoma occurs more in Nigerian than in American and Danish males. Mucinous carcinoma, on the other hand, appears much more common in the Danish than in the Nigerian and American males. In all the compared races, prognosis in male breast cancer appears to depend on the age at onset of the disease, the histological type, and presence or absence of lymph node metastases. In Nigerian males mucinous carcinoma appears to offer an excellent prognosis compared with papillary carcinoma, which has better prognostic features in American male patients.
男性乳腺癌占伊巴丹所有男性肿瘤的0.4%，约占所有女性和男性乳腺癌的3.4%。常见的临床特征包括乳房肿块、皮肤因固定和溃疡而受累、乳头血性和浆液性溢液。症状往往出现较晚，本系列中最长病程为36个月。男性乳腺癌组织学类型的地域比较似乎表明，虽然乳头状癌在尼日利亚男性中比在美国和丹麦男性中更常见，但浸润性导管癌在后者中比在前述男性种族中更为常见。浸润性小叶癌在尼日利亚男性中比在美国和丹麦男性中更常见。另一方面，黏液癌在丹麦男性中似乎比在尼日利亚和美国男性中更为常见。在所有比较的种族中，男性乳腺癌的预后似乎取决于疾病发病年龄、组织学类型以及有无淋巴结转移。与乳头状癌相比，黏液癌在尼日利亚男性中似乎预后良好，而乳头状癌在美国男性患者中具有更好的预后特征。
