Isolated Splenic Metastasis from Invasive Lobular Carcinoma Breast

Abstract

Breast carcinoma is the most common malignancy of women worldwide. Distant metastases are seen most commonly in the skeletal system, lung and pleura, liver, ovary, adrenal gland, and central nervous system. Invasive lobular carcinoma of the breast is the second most common histologic type of invasive breast cancer after invasive ductal carcinoma Spleen is a reticuloendothelial organ and its tumors present a diagnostic dilemma. The reticuloendothelial system may help to inhibit the initial phase of tumor cell seeding. Splenic metastasis is infrequent. Isolated splenic involvement is exceedingly rare as usually it is associated with multiorgan metastasis and is asymptomatic. Splenic involvement is usually detected through routine follow-up imaging and is an incidental finding. Computerized tomographic scan of the abdomen remains the gold standard to detect splenic metastasis. We present a case of isolated splenic cystic synchronous metastasis from infiltrating lobular carcinoma of breast in a 62 years old female.
