Summary
The first reported Japanese case of alveolar hydatid disease presented with skin and subcutaneous lesions. This rare condition, echinococcosis, poses significant treatment challenges.
Area of Science:
- Parasitology
- Dermatology
- Surgical Pathology
Background:
- Alveolar hydatid disease, caused by Echinococcus multilocularis, is a rare parasitic infection.
- Subcutaneous manifestations of alveolar hydatid disease are exceptionally uncommon, with few documented cases globally.
Observation:
- A 58-year-old Japanese male presented with an abdominal subcutaneous tumor.
- The patient had a history of partial hepatectomy for echinococcosis 13 years prior.
- Clinical examination revealed adherence and fistulous communication to deeper structures.
Findings:
- Histopathology showed characteristic PAS-positive cuticular layers, foreign body granulomas, and fibrosis.
- Surgical excision offered only temporary symptom relief, indicating disease complexity.
Implications:
- This case represents the ninth documented instance of subcutaneous alveolar hydatid disease worldwide.
- It underscores the diagnostic and therapeutic difficulties associated with this rare parasitic infection.
- Highlights the need for increased awareness and specialized management strategies for cutaneous-subcutaneous echinococcosis.
