Summary
A rare spontaneous cholecystocutaneous fistula was diagnosed in a male patient through histological examination of a skin biopsy. This case highlights the importance of histology for diagnosing unusual biliary tract complications.
Area of Science:
- Gastroenterology and Hepatology
- Dermatology
- Pathology
Background:
- Spontaneous cholecystocutaneous fistula is a rare complication of biliary tract disease.
- Advancements in antibiotics and imaging have reduced its incidence.
- Diagnosis can be challenging due to non-specific symptoms and insidious onset.
Observation:
- A 65-year-old male presented with a chronic, ulcerated skin lesion on his right flank.
- Initial investigations including ultrasound were inconclusive.
- The lesion had a long-standing, asymptomatic course prior to presentation.
Findings:
- Histopathological examination of the skin biopsy revealed granulomatous inflammation with embedded biliary fragments.
- Intraoperative findings suggested a biliocutaneous fistula secondary to gallbladder inflammation.
- This confirmed a rare spontaneous cholecystocutaneous fistula.
Implications:
- Systemic histological examination is crucial for diagnosing rare conditions like spontaneous cholecystocutaneous fistula.
- This case underscores the need for thorough diagnostic evaluation when faced with unusual cutaneous presentations.
- Accurate diagnosis through histology is vital for appropriate management of complex biliary-cutaneous fistulas.
