T cell/histiocyte rich large B cell lymphoma of ascending colon: a rare entity

Colonic T cell/histiocyte rich large B cell lymphoma (THRLBCL) is a very unusual occurrence never described before. A 41-year anaemic male presented with loss of weight and appetite for 7 months and fever with Malena for 1 month. Abdominal examination revealed a 4×6 cm retroperitoneal lump in the right iliac fossa. Radiological investigations (USG and CECT whole abdomen) reported an asymmetrical ill-defined growth in ascending colon and caecum with loco-regional lymphadenopathy. Surgical exploration revealed an ascending colon mass with retroperitoneal lymphadenopathy. Right hemi-colectomy with end ileostomy was done and specimen was sent for histopathology which diagnosed it to be a case of THRLBCL of colon. Patient was followed up after 2 weeks and was planned for chemotherapy.
