Double trouble: Synchronous T-cell lymphoma and colonic adenocarcinoma.

Abstract: Synchronous tumors consisting of colorectal adenocarcinoma and lymphoma are infrequent and pose a tricky situation to the clinicians for the management. We present a case of a 67-year-old male ex-alcoholic who presented with loss of appetite, weight loss for 3 weeks, high fever, abdominal pain for 2 days, and difficulty in passing stool for 1 month. Upon examination and further investigations, a diagnosis of stage 4 peripheral T-cell lymphoma, moderately differentiated sigmoid colon adenocarcinoma with liver metastasis, and SIADH-tumor associated was made. In light of the case's metastatic disease, the tumor board opted to proceed with stenting for the sigmoid colon mass and chemotherapy for the peripheral T-cell lymphoma. It is certain that with the development of regular screening programs and extensive evaluation across the country, early identification and diagnosis can lead to efficient treatment plans and can improve the prognosis significantly.
