Ex vivo MRI of axillary lymph nodes in breast cancer.

Purpose: To provide a strategy for precise co-localization of lymph nodes on axillary lymph-node dissection (ALND) specimens both on pathology and MR. To identify nodal features suggestive of metastatic involvement on a node-to-node basis.

Materials And Methods: National Institutional review-board approved this prospective study of 18 patients with breast cancer referred for ALND.

Metastasis of a breast carcinoma in a mature teratoma of the ovary.

Metastatic tumors in ovaries from breast carcinoma are well known. Breast carcinoma metastases in primary ovarian tumors are much more uncommon. The authors present a case of a primary breast carcinoma, with a lobular component (signet ring cells), which metastasized into a mature cystic teratoma of the ovary.
