Abstract:
Development of a neoplasm in an ectopic breast is uncommon, while the development of phyllodes tumor in an ectopic breast in the axilla is even rarer. We report a rare case of a 51-year-old female who presented with a complain of swelling and pain in the right axilla with no associated complaints in other organs. Magnetic resonance imaging suggested a possibility of metastatic lymphadenopathy. Complete excision of the right axillary mass was performed and sent for histopathological examination which was examined thoroughly and sections were given. On microscopic examination, stromal proliferation in a leaf-like pattern with mild stromal atypia and focal permeation of borders were seen, and a diagnosis of Ectopic borderline phyllodes tumor in axilla was made, which is extremely rare and needs to be differentiated from its close differentials like fibroadenoma and periductal stromal sarcoma.
摘要:
异位乳腺肿瘤的发展并不常见,而腋窝异位乳腺叶状肿瘤的发展更为罕见。我们报告了一例罕见的51岁女性病例,该女性在右腋下出现肿胀和疼痛的抱怨,在其他器官中没有相关的抱怨。磁共振成像提示转移性淋巴结病的可能性。对右腋窝肿块进行了完全切除,并进行了组织病理学检查,对其进行了彻底检查并进行了切片。在显微镜检查中,可见叶样模式的基质增殖,具有轻度的基质异型性和边界的局灶性渗透,并诊断为腋窝异位交界叶状肿瘤,这是非常罕见的,需要从其紧密的区别,如纤维腺瘤和导管周围间质肉瘤。
