摘      要:A 59-year-old woman was admitted to our hospital because of recurrent follicular lymphoma(FL).Colonoscopic examination revealed a rectal submucosal tumor(SMT)without any erosions and *** this patient,it was difficult to distinguish non-Hodgkin s lymphoma(NHL)invasion from other disorders of the colon including carcinoid tumor merely based on endoscopic *** and immunohistochemical studies on biopsy specimens showed an infiltration of atypical lymphocytes that were positive for CD20 and BCL2 but negative for *** in situ hybridization on paraffin-embedded tissue sections (T-FISH)identified a translocation of BCL2 with IGHgene. Based on these findings,the tumor was defined as an invasion of FL.T-FISH method is useful for the detection of a monoclonality of atypical lymphocytes in an SMT of the gastrointestinal tract,and particularly for the detection of chromosomal translocations specific to lymphoma subtypes.
