Abstract
Multiple lymphomatous polyposis is an unusual form of non-Hodgkin's lymphoma characterised by myriad polyps throughout the alimentary tract. Most multiple lymphomatous polyposis cases are derived from B-cell, and there has been little information on multiple lymphomatous polyposis of T-cell origin. A 67-year-old Japanese man presented with lower abdominal pain and diarrhoea of 4-week duration. Colonoscopy revealed numerous small umbilicated polyps and several raised erosions in the colorectum. Biopsy specimens showed diffuse proliferation of lymphoma cells negative for B-cell markers but positive for T-cell markers. Polymerase chain reaction using extracted chromosomal deoxyribonucleic acid from paraffin-embedded samples identified T-cell receptor gamma and delta gene recombination. The patient was treated with combined chemotherapy, leading to complete resolution of the lesions.
