诊断男性患者的副乳腺组织是困难的，当条件是单侧的，没有乳晕或乳头。乳腺间质的假血管瘤样增生是一种罕见的良性间质增生，可能类似于低度恶性血管肉瘤。我们在此报告一位38岁男性的副乳腺组织发生肿瘤样假血管瘤样增生，表现为可触及的腋窝压痛肿块。组织病理学检查未见男性乳房发育改变。此前仅报道过两例在单侧或双侧男性乳房发育症男性的副乳腺组织中出现间质假血管瘤增生的病例。我们的病例是第一个没有相关的男性乳房发育症的报告。影像学特征不足以特异性地对间质假血管瘤样增生进行前瞻性诊断。病变的显微镜检查是作出明确诊断必不可少的。认识到这种情况可以避免诊断上的困难。异常乳腺组织伴肿块形成的假血管瘤样增生的间质，虽然罕见，但应包括在腋窝良性增生性间叶病变中。关键词：迷走乳腺组织-副乳腺组织-假血管瘤性间质增生-男性乳房发育-血管瘤-腋窝。
Diagnosing accessory breast tissue in a male patient is difficult when the condition is unilateral, and there is no areola or nipple. Pseudoangiomatous hyperplasia of the mammary stroma is an uncommon benign mesenchymal proliferation that may mimic low-grade angiosarcoma. We report herein an example of tumoriform pseudoangiomatous hyperplasia of the stroma arising in the accessory breast tissue of a 38-year-old man. The condition presented as a palpable tender axillary mass. Histopathologically, there were no changes of gynecomastia. Only two cases of pseudoangiomatous hyperplasia of the stroma have been previously reported in the accessory breast tissue of men showing unilateral or bilateral gynecomastia. Our case is the first report without associated gynecomastia. Radiologic imaging features are not sufficiently specific to enable a prospective diagnosis of pseudoangiomatous hyperplasia of the stroma. Microscopic examination of the lesion is indispensable in making a definitive diagnosis. Awareness of the condition can avoid difficulty in diagnosing it. Aberrant breast tissue with mass-forming pseudoangiomatous hyperplasia of the stroma, whilst rare, should be included among the benign proliferative mesenchymal lesions of the axilla.
