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.
