摘要
We report a case of a 27-years-old woman with a lesion at the right breast, incidentally noted. The patient underwent tumour resection followed by a right mastectomy type "Patey". Microscopic analysis of the tumour had recognised an invasive pleomorphic lobular carcinoma. Invasive pleomorphic lobular carcinoma (PLC) is a distinctive aggressive subtype of invasive lobular carcinomas (ILC). It has the typical infiltrating pattern of classical ILC of diffuse single cell spread but the nuclei are more pleomorphic. Histological differential diagnosis with ductal carcinoma may be difficult, but it is important for this difference to be done. E-cadherine is a trans-membrane glycoprotein, typically expressed in ductal carcinoma, and loss of E-cadherine expression characterises invasive and in situ lobular carcinoma.
