Primary sarcomas arising in lymph node are few and far between. They are believed to arise from either follicular dendritic cells, indeterminate dendritic cells, interdigitating dendritic cells and seldom from fibroblastic reticular cells which are said to have mesenchymal origin and are involved in cytokine transport. A 37-year-old female patient reported with painless mass in axilla without any breast lump. On histopathology a diagnosis of NHL was made which on immunohistochemistry with CK8, CK18 and SMA positivity was diagnosed as fibroblastic reticulum cell tumour. The case is being reported because of its rarity. Keywords: Fibroblastic reticular cells, Immunohistochemistry, Lymph node, Stromal cells, Sarcoma.
