An Uncommon Breast Odyssey: A Rare Case of Carcinoma Breast with Mesenteric Metastasis.

We present an unusual case of invasive ductal breast carcinoma in a postmenopausal female with a clinically node-negative disease that was incidentally found to have mesenteric metastatic deposits on ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography scan. Mesenteric metastasis from invasive breast carcinoma is rare, with <1% cases reported worldwide and limited availability of diagnostic and therapeutic protocols for carcinoma breast with mesenteric metastasis, this proved to be a challenging and intriguing case. To further accentuate the complexity, the primary tumor of this mesenteric metastasis was found to be invasive ductal carcinoma, which is even more infrequent, and <0.5% of cases have been reported till date.
