Summary
Primary gallbladder sarcoma is a rare, aggressive cancer, more common in women, often presenting with symptoms similar to gallstones. This case highlights the poor prognosis and challenges in early diagnosis of this rare malignancy.
Area of Science:
- Oncology
- Gastroenterology
- Surgical Pathology
Background:
- Primary sarcoma of the gallbladder is an exceptionally rare malignancy.
- This tumor predominantly affects women and is frequently associated with gallstones.
- Clinical presentation often mimics benign gallbladder conditions like cholelithiasis or cholecystitis, complicating preoperative diagnosis.
Observation:
- A 51-year-old woman presented with right upper quadrant pain, nausea, vomiting, and weight loss.
- Initial ultrasound revealed gallstones and cholecystitis.
- Intraoperative findings during cholecystectomy included dense gallbladder tissue, liver surface implants, and peritoneal metastasis, necessitating conversion to open surgery.
Findings:
- Pathological examination confirmed poorly differentiated epithelioid leiomyosarcoma of the gallbladder with hepatic extension.
- The disease exhibited an aggressive clinical course, leading to the patient's death within three weeks of surgery.
- Metastatic spread to the liver and peritoneum was evident.
Implications:
- Early diagnosis of gallbladder sarcoma is challenging due to non-specific symptoms.
- Aggressive surgical resection, potentially combined with adjuvant radiotherapy or chemotherapy, is the recommended treatment approach.
- The prognosis for gallbladder sarcoma is generally poor, with limited long-term survival rates reported.
