Synchronous colorectal cancer (SCRC) is characterized by the simultaneous occurrence of two or more primary colorectal malignancies, diagnosed either preoperatively, intraoperatively, or within six months postoperatively. The rare prevalence of SCRC makes it an uncommon scenario among colorectal malignancies. Since the majority of SCRC patients have been reported to have two concurrent malignancies, triple synchronous malignancies are extremely rare. We report the case of a 65-year-old male individual presenting with a history of abdominal pain, anemia, anorexia, and unintentional weight loss. He was diagnosed with synchronous colorectal cancer with three distinct tumors: two located in the splenic flexure and sigmoid colon, respectively, and another in the rectum that caused partial obstruction. This case highlights the importance of intraoperative evaluation and an appropriate choice of surgical intervention in colorectal cancer. The early identification and proper management of multiple colorectal cancers remain essential for better survival rates.

Peptic ulcer perforations are common in surgical emergencies, whereas double perforations are rare, and triple peptic perforations are even exceedingly rare, with only a few cases documented. While undetected perforation during surgery can be fatal, the absence of standardized procedures for managing multiple perforations remains an ongoing challenge for surgeons. Herein, we describe a rare case of simultaneous triple peptic perforations in an elderly man with a prolonged history of analgesic and corticosteroid use. This case underscores the importance of screening multiple peptic perforations intraoperatively. Subtotal gastrectomy is suggested as an effective option when simple closure of perforations is infeasible.
