case_images: Abdominal ultrasound and computed tomography revealed nodular thickening in the transverse and right colon with infiltration of pericolonic fat and a few subcentimeter lymph nodes (Figure 1). The patient was diagnosed with ITCL, NOS and further computed tomography scan revealed adrenal nodes (23 x 31 mm) and 14 mm long axis latero cava lymphadenopathy, classified as stage VI according to the Ann Arbor classification (Figure 1). The abdominal CT scan did not show any other deep lymphadenopathy. The thoracic CT scan did not show any lymphadenopathy and we did not proceed with a PET scan (Figure 1).

case_images: Colonoscopy detected polypoid mass lesions with ulceration ranging from 3 to 4 cm in size in the transverse and right colon (Figure 2).
case_images: Histological examination.. (A) A diffuse infiltrate of the colon mucosa that didn't invade crypts (HE x 200). (B) The infiltrate was composed of medium to large cells with atypical nuclei and numerous mitoses (HE x 400).
