Non-Hodgkin’s Lymphoma Presenting as a Soft Tissue Mass on Right Thigh

Abstract

Non-Hodgkin’s Lymphomas (NHL) are a heterogeneous group of lymphoproliferative malignancies with a greater preference for disseminating to extranodal locations. Prevalence of extranodal involvement in NHL has increased in the past decade, and the sites involved are the stomach, spleen, waldeyer’s ring, Central Nervous System (CNS), lungs and skin. This is a rare case of NHL in a 48-year-old female who presented with solitary exophytic mass with ulceration over the right thigh and erythematous plaque over postaxillary region and enlarged right inguinal and left axillary lymph nodes. Magnetic Resonance Imaging (MRI) of the right thigh showed lobulated mass involving skin and subcutaneous soft tissues without any intramuscular extension suggestive of neoplastic mass. Fine needle aspiration cytology of the inguinal node and biopsy of the right thigh lesion showed features suggestive of NHL. She was treated with three cycles of Cyclophosphamide, Hydroxydaunorubicin, Oncovin and Prednisone (CHOP) regimen, but the patient succumbed to death after six months of chemotherapy.
