Primary or secondary lymphoma is a malignity that occurs in the prostate. The 64-year-old male patient appealed to our clinic with discomfort, nausea and weight loss complaints. As a result of the evaluation of the gastrointestinal system, a biopsy from the ulcerative mass observed at the colonoscopy / output colon level was taken and the result was as adenocarcinoma. The F-18 fluorodeoxyglycosis Pozitron emission tomography for evolutionary purposes; many hypermetabolic masses and lithium-specific lesions were observed in the soft tissue and outgoing column, in the neck-mediast-pneumocytes and in the west, including diffuse, localized in the neck-mediast-pneumocytes and in the left femur. An intense hypermetabolic focus (SUVmax: 18.4) was observed on the left top side of the prostate gland. In urological assessment, the digital rectal examination and the prostate specific antigen were normal. In the patient with a biopsy of the 12 cor prostate injection, a CD 20 and BCL 2 positive, CD 3 negative were observed. Compatible with other tissue biopsy, the secondary diffuse of the prostate was as large B-cell lymphoma. The number of cases similar to this phenomenon of concomitant colon adenocarcinoma, common metastatic diffuse large B cell lymphoma and secondary prostate lymphoma is quite rare in literature; it is necessary to keep in mind that the possibility of metastasis in patients with normal rectal examination and prostate specific antigen levels normally detected cannot be excluded.
