Ectopic prostatic tissue and seminal vesicle at pericolic fat is extremely rare. The nodules in the pericolic fat could raise a dilemma of metastatic deposits in cases of rectal adenocarcinoma. A 61 years old male underwent abdomino-perineal resection for rectal carcinoma. Nodules along with lymph nodes from pericolic fat were sampled to assess the spread. Histopathological and immunohistochemical staining of one nodule confirmed it to be the prostatic tissue while another nodule to be seminal vesicle. Seminal vesicle and prostatic heterotopia is significant in several respects, either symptomatic or asymptomatic, as the ectopic tissue can be endoscopically and histologically confused with malignancy of urinary or lower gastrointestinal system and may reflect divergent differentiation or a malformative process.
