Abstract
BACKGROUND
Rectal mucinous adenocarcinoma (MAC) is a rare pathological type of rectal cancer with unique pathological features and a poor prognosis. It is difficult to diagnose and treat early because of the lack of specific manifestations in some aspects of the disease. The common metastatic organs of rectal cancer are the liver and lung; however, rectal carcinoma with metastasis to subcutaneous soft tissue is a rare finding.
CASE SUMMARY
In this report, the clinical data, diagnosis and treatment process, and postoperative pathological features of a patient with left waist subcutaneous soft tissue masses were retrospectively analyzed. The patient underwent surgical treatment after admission and recovered well after surgery. The final pathological diagnosis was rectal MAC with left waist subcutaneous soft tissue metastasis.
CONCLUSION
Subcutaneous soft tissue metastasis of rectal MAC is rare, and it can suggest that the tumor is disseminated, and it can appear even earlier than the primary malignant tumor, which is occult and leads to a missed diagnosis and misdiagnosis clinically. When a subcutaneous soft tissue mass of unknown origin appears in a patient with rectal cancer, a malignant tumor should be considered.
Core Tip: Mucinous adenocarcinoma (MAC) is a relatively rare pathological subtype of colorectal cancer. Patients with rectal MAC are more likely to have abdominal lymph node metastasis, peritoneal metastasis, and abdominal implantation and have a worse prognosis and lower survival rate. Early detection, diagnosis, and treatment of rectal MAC can improve the prognosis of patients. We present a rare case of left waist subcutaneous soft tissue metastasis, hoping to provide some experience for the early clinical diagnosis and treatment of this disease.
