Metaplastic squamous cell carcinoma in association with invasive lobular breast carcinoma with metastasis to axillary lymph nodes.
J Ayub Med Coll Abottabad Jan ;23(4):135-7.

Squamous cell carcinoma (SCC) of the breast is very rare entity and when encountered it is found in association with invasive ductal carcinoma of the breast. We report a very unusual association of an invasive lobular carcinoma with metaplastic squamous cell carcinoma of the breast which was found not only in a mastectomy specimen but also in the axillary lymph nodes. The patient reported first with a lump breast which was diagnosed a case of invasive lobular carcinoma in a lumpectomy specimen, followed by adjunct radiation and chemotherapy. We encountered such association in only one case report in the literature.
