Retroperitoneal dermoid presenting as an infected pancreatic cyst

Area of Science:

• Gastroenterology
• Surgical Oncology
• Infectious Diseases

Background:

• Retroperitoneal teratomas are rare germ cell tumors.
• Juxtapancreatic locations present unique diagnostic challenges.
• Infection of cystic neoplasms is uncommon.

Observation:

• A 28-year-old male presented with a juxtapancreatic benign cystic retroperitoneal teratoma.
• The teratoma was infected with Bacteroides fragilis.
• Radiological and pathological evaluations were performed.

Findings:

• The study details the radiological and pathological findings of this infected teratoma.
• Bacteroides fragilis was identified as the causative agent.
• Differential diagnosis included inflammatory and neoplastic pancreatic cysts.

Implications:

• This case highlights the importance of considering infection in cystic retroperitoneal masses.
• Accurate diagnosis is crucial for appropriate management, distinguishing between neoplastic and inflammatory lesions.
• Surgical management involving drainage and excision is effective for infected teratomas.
