ABSTRACT
Squamous cell carcinoma (SCC) involving the gastrointestinal tract is exceptionally rare, except in the esophagus and the anal canal. In the hindgut, a common site of involvement is the colo-rectum, commonly seen in the fifth decade of life. The presentation is usually in the advanced stages and carries a poor prognosis. Due to the rarity of the disease, before labeling it as a primary lesion, the possibility of metastasis from a distant primary should be entertained. Consensus guidelines regarding the management of such a rare condition are lacking. Here, we present the case of an elderly gentleman with a history of surgery for urinary bladder cancer 20 years back (the nature of which is not known). The patient presented with left lower abdominal pain and altered bowel habits. His pain had persisted for approximately two months along with a recent onset of overflow incontinence but no other associated constitutional symptoms. Examination revealed pallor and a vague abdominal mass in the left iliac fossa. On further evaluation with a colonoscopy, a growth was seen in the sigmoid colon. Computed tomography of the abdomen revealed a locally invasive growth arising from the sigmoid colon along with a space-occupying lesion in the left lobe of the liver enhancing on the portal phase. Biopsy from the sigmoid and the liver lesion was reported as SCC which was confirmed by immunohistochemistry. Given the metastatic nature of the lesion, treatment options were discussed in a multidisciplinary team setting, and the decision was made to proceed with diversion colostomy and palliative chemotherapy. SCC of the colon is a rare disease and is usually diagnosed at an advanced stage. Even in operable cases, the prognosis is dismal, and various treatment modalities have been attempted. Due to the rarity of the disease and paucity of data regarding definitive management, treatment varies from one patient to another.
