Summary
Recurrent nevi contain S-100 protein-positive cells, suggesting residual nevus cells may remain after incomplete removal. These findings aid in understanding nevus recurrence and scar formation.
Area of Science:
- Dermatopathology
- Surgical Pathology
Background:
- Recurrent nevi can occur after incomplete excision.
- The cellular origin of recurrent nevi requires further elucidation.
Purpose of the Study:
- To investigate the cellular composition of recurrent nevi using immunohistochemistry.
- To identify potential cell types contributing to nevus recurrence.
Main Methods:
- Immunohistochemical analysis of eight recurrent nevus cases.
- Utilized antibodies for S-100 protein and Factor XIIIa.
Main Results:
- S-100 protein-positive and Factor XIIIa-negative fibroblast-like cells were identified.
- These cells were observed within and surrounding scar tissue.
- Cells were found adjacent to vessels and dispersed in fibrotic areas.
Conclusions:
- The identified cells likely represent entrapped or migrating nevus cells.
- Incomplete removal of deep nevus portions may lead to recurrence.
- Findings contribute to understanding the pathogenesis of recurrent nevi.
