Introduction:
Primary colorectal lymphoma (PRL) accounts for 1.4% of all cases of
non-Hodgkin’s lymphoma (NHL) and less than 1% of all colorectal
malignancies. Although the gastrointestinal (GI) tract is the most
common site of extranodal lymphoma, colorectal lymphoma is rare
[1].
Dawson and al established criteria for the diagnosis of PRL in 1961
including the absence of clinically enlarged lymphadenopathy in physical
examination, the absence of enlarged mediastinal lymph nodes on chest
x-ray, normal white blood cell count and bone marrow biopsy, and the
absence of abnormalities of the liver and spleen
[2].
While treatment strategies in nodal NHL are well established, management
of PRL is still unclear [3]. We present the case of a 38-year-old
woman, diagnosed with a stage IIE PRL
