Summary
The dilated pore, a rare skin neoplasm, is distinct from cysts and other proliferations. It uniquely differentiates towards the follicular infundibulum, a finding supported by histological evidence.
Area of Science:
- Dermatopathology
- Surgical Pathology
Background:
- The dilated pore is a rare skin lesion.
- Histological differentiation of follicular structures is complex.
Purpose of the Study:
- To re-evaluate Louis H. Winer's description of the dilated pore.
- To differentiate the dilated pore from other follicular proliferations and cysts.
Main Methods:
- Review of pertinent literature on the dilated pore.
- Histological analysis of follicular infundibulum and isthmus.
- Comparative analysis of architectural and cytologic differentiation.
Main Results:
- Evidence presented contradicts the classification of the dilated pore as solely a cyst.
- Other purported infundibular neoplasms lack specific differentiation.
- The dilated pore exhibits unique differentiation towards the infundibulum.
Conclusions:
- The dilated pore is a neoplasm sui generis.
- It is the sole cutaneous neoplasm differentiating towards the infundibulum (infundibuloma).
