“…Colorectal cancers (CRC) diagnosed 6 months after the primary CRC surgery is termed metachronous CRC [ 11 , 12 ]. The incidence of colonic and rectal metachronous tumors are reported to be 0.3-0.35% per year which could potentially present even decades after the index CRC [ 13 ].…”

Granular cell tumors (GCTs) are uncommon tumors. They are believed to be neuronal in origin and are usually found in the head and/or neck area of the body. They have also been reported in various locations of the gastrointestinal (GI) system, usually discovered during routine screening colonoscopy. We report a case of GCT in a 58-year-old asymptomatic African American female as a metachronous tumor of a well-differentiated adenocarcinoma of the sigmoid colon, which was an incidental finding in screening colonoscopy. To our knowledge, this is the first case with GCT identified as a metachronous tumor following an adenocarcinoma of the colon.

Metachronous colorectal cancer is relatively rare, occurring in 0.7–3.6% of patients diagnosed with colorectal adenocarcinoma. Cutaneous metastases are similarly a rare presentation, occurring in <6% of metastatic colorectal cancer patients. Even more rare are the cutaneous recurrences at the peristomal site. Clinically, it is difficult to distinguish between metachronous cancer and cutaneous metastases. This paper reports a case of an elderly woman presenting with a slowly progressing peristomal cutaneous lesion 16 years after surgical resection for colorectal cancer. Core punch biopsy revealed a cutaneous localization of an intestinal type of adenocarcinoma. A surgical resection of the peristomal area was carried out whereby a new colostomy was created on the contralateral side. Definite histopathological examination showed a superficially located intestinal type adenocarcinoma with extensive pagetoid spread in the epidermal surface. In conclusion, it is important to remain alert and strive for early detection for cutaneous abnormalities following colorectal cancer.
