Unusual case of follicular lymphoma presenting as solitary painless scalp swelling: Case report and review of literature

Abstract

Follicular lymphoma (FL) is the second most frequent non-Hodgkin lymphoma accounting for about 10%–20% of all lymphomas. FL usually presented with peripheral adenopathy involving cervical, inguinal, and femoral regions. FL presenting as a scalp swelling without involvement of underlying cerebral parenchyma or systemic manifestation in a nonimmunocompromised patient is an extremely rare medical condition requiring aggressive treatment and neurosurgical intervention. We report the case of a 33-year-old male presenting with progressively increasing painless large left-sided frontal scalp swelling. The patient underwent near-total excision of lesion. Histopathology report suggested FL. We report this case for discussion regarding pathophysiology, diagnosis, and appropriate clinical management.
