Summary
A ruptured plantar epidermal inclusion cyst involving the fourth common digital nerve was surgically removed. This case highlights a rare nerve complication and demonstrates successful treatment with no recurrence.
Area of Science:
- Podiatric Surgery
- Neurology
- Dermatopathology
Background:
- Epidermal inclusion cysts are common benign skin lesions.
- Plantar epidermal inclusion cysts are rare and can cause diagnostic challenges.
- Involvement of peripheral nerves by epidermal inclusion cysts is exceptionally uncommon.
Observation:
- A case of a ruptured, multilobular epidermal inclusion cyst on the plantar aspect of the foot is presented.
- The cyst was found to involve the fourth common digital nerve, a rare anatomical complication.
- Magnetic resonance imaging (MRI) was utilized to visualize the foot lesion and its relationship with the nerve.
Findings:
- Surgical excision was performed as the treatment modality for the ruptured plantar epidermal inclusion cyst.
- Histopathological examination confirmed the diagnosis of an epidermal inclusion cyst.
- Post-operative follow-up revealed no evidence of cyst recurrence.
Implications:
- This case underscores the importance of considering nerve involvement in plantar epidermal inclusion cysts.
- Accurate diagnosis and complete surgical excision are crucial for successful management and preventing recurrence.
- The findings contribute to the limited literature on plantar epidermal inclusion cysts and their neurological complications.
