Cutaneous and Subcutaneous Metastases of Adenocarcinoma of the Colon and Rectum



Introduction: The interesting topic of cutaneous and subcutaneous metastasis from rectal carcinoma is discussed using 3 cases.

Clinical Picture: The first case was a 70-year-old man with T3N2M0 rectal mucinous adenocarcinoma, who developed an inflammatory subcutaneous metastasis at the left scapula 2 years after anterior resection. The second case was a 51-year-old man with T4N2M0 splenic flexure mucinous adenocarcinoma, who developed metastatic disease including a subcutaneous secondary to the back. The third case was a 53-year-old woman who developed vulval recurrence 10 months after abdomino-perineal resection for a low T3N1M0 rectal adenocarcinoma.

Treatment: All underwent wide resection.

Conclusion: This entity is rare and usually signifies disseminated disease if found remote from the resection site and warrants a thorough metastatic work up. A high index of suspicion is recommended when encountered with unresolving skin lesions in cancer patients.

Cutaneous metastasis from colorectal adenocarcinoma is an interesting condition not only because of its rarity, it occurs in less than 4% of patients with colorectal cancers, but also because it implies a poor prognosis. We discuss 3 patients with rectal adenocarcinoma who subsequently developed cutaneous metastases.
