Triple synchronous primary malignancies: a rare occurrence

Triple synchronous primary malignant neoplasms are rare. The exact aetiology is unknown; however, risk factors include older age, family history, genetic aberrations, prolonged exposure to carcinogens and smoking. We describe a previously healthy 48-year-old woman who presented with abdominal pain and a palpable abdominal mass. Imaging revealed a complex cystic, solid pelvic mass and another mass in the right upper quadrant. She received an extensive abdominal surgery including exploratory laparotomy, pelvic mass resection, total abdominal hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic lymphadenectomy, omentectomy and right adrenalectomy. During surgery, a mass in the distal sigmoid colon was noted and subsequent sigmoidectomy was performed. The surgical specimen revealed three different primary tumours with three different histologies, a granulosa cell tumour of the ovary, adrenocortical carcinoma and adenocarcinoma of the colon. She received six cycles of adjuvant chemotherapy for colon cancer with 5-fluorourocil, leucovorin and oxaliplatin and is currently living with no recurrence.
