Non-Hodgkin's lymphoma of T lymphoblastic type of mediastinum and breast, mimicking thymoma

Divakar Bhat, Bhagyashree Jagadeeshwara


T cell lymphoblastic lymphoma (T-LBL) is a common variant of Non-Hodgkin’s tumor of mediastinum which presents late due to aggressive spread. Immunohistochemical studies are conclusive in their diagnosis. We present a rare case of mediastinal tumor with left breast mass which mimicked thymoma on computed tomography guided biopsy but was diagnosed T-LBL on immunohistochemistry after surgical excision.
