Microscopically it is a 0.8 cm lesion as photo.
Your diagnosis and differential diagnosis.
(镜下病变直径0.8cm,如图。请诊断和鉴别诊断)
Looks like tubular carcinoma, a well differentiated invasive ductal carcinoma. It requires >75%(?) tubular formation in neoplastic glands. Lower right hand portion of the photo shows possible low grade DCIS. The stroma probably represents desmoplastic response to those tumor glands. I talk with uncertain tone "probable, possible, looks like" because a single photomicrograph is a very limited source for a significant diagnosis, i cannnot be very sure.
abin译:
像小管癌,属于一种分化好的浸润性导管癌。它要求肿瘤性腺体中小管结构>75%(译注,这个标准有争议,有人严格要求100%。WHO认为小管结构达90%作为诊断标准可能较为妥当)。
右下可能为低级别DCIS。间质可能是促结缔组织反应。
