Summary
Winer's dilated pore, a rare benign hair follicle tumor, can mimic serious ear canal lesions. Early diagnosis and appropriate management are crucial to avoid aggressive treatment for this non-specific condition.
Area of Science:
- Dermatopathology
- Otolaryngology
Background:
- Hair follicle tumors are uncommon and often present with non-specific clinical signs.
- Early identification is key to appropriate patient management.
Observation:
- A 51-year-old female presented with a chronic discharging ear unresponsive to treatment.
- Microscopic examination revealed a keratinous collection and skin defect, with CT showing bony rarefaction.
Findings:
- Histological diagnosis confirmed Winer's dilated pore, a benign tumor of the pilosebaceous unit.
- Grossly, the lesion presented a keratotic plug, and microscopically, a skin defect with potential bone erosion.
Implications:
- Winer's dilated pore can be misdiagnosed as squamous cell or basal cell carcinoma, leading to unnecessary aggressive treatment.
- This case highlights the importance of considering rare benign lesions in the differential diagnosis of ear canal pathologies.
