Primary signet-ring cell carcinoma of the cecum: A rare case report.

INTRODUCTION AND IMPORTANCE

Primary SRCC is a rare histological colorectal cancer subtype. It is characterized by distinct clinical presentation.

CASE PRESENTATION

This case report describes a rare case of a Primary Signet-ring cell carcinoma of the cecum. A 37-year-old man came to the emergency department with bowel obstruction and altered general condition. The abdominal CT scan showed an intestinal occlusion upstream a thickening of the cecum. An exploratory laparotomy found a distention of the bowl with a suspect thickening of the cecum. The patient underwent a right ileo-colectomy and ileocolostomy. Histologic analysis of the operatory specimen confirmed the diagnosis of a primary Signet-ring cell carcinoma of the cecum. The recovery was uneventful, and the patient is in good health after six -months of follow-up. After completing the chemotherapy, the patient is scheduled for a colonoscopy and reversal of colostomy.

CLINICAL DISCUSSION

Colorectal primary signet ring cell carcinoma (SRCC) is a rare entity, and it is associated with poor prognosis compared with common colorectal adenocarcinomas. characterized by distinct clinical presentation, with very poor response rates.

CONCLUSION

Primary SRCC is an aggressive histological type of colon cancer and it is associated with a poor prognosis. There are no conclusive guidelines for the treatment of this type of tumor.
