Abstract
B-cell lymphoblastic lymphoma (B-LBL) is a malignant neoplasm of immature B cells that accounts for only 10% of all cases of lymphoblastic lymphoma. Most commonly, B-LBL presents as bony lesions, but in rare cases, the disease manifests cutaneously. We present a case of simultaneous cutaneous and systemic presentation of B-LBL in an otherwise healthy 28-year-old man in which the lymphoblastic infiltrate stained positive for CD79a, Tdt, CD10, and CD20. A diagnosis of cutaneous B-LBL was made, and systemic work-up revealed widespread involvement of the skin, bone, and lymph nodes. Review of all currently described cases of cutaneous B-LBL with or without systemic involvement revealed that the most frequently positive tumor markers were CD79a (92.3%), Tdt (90.6%), and CD10 (83.3%). Systemic involvement of B-LBL was found in nearly half of all cases with cutaneous presentation.
