Summary
Hair transplantation surgery can rarely lead to scalp conditions like dissecting folliculitis (PCAS). This case suggests follicular unit extraction may trigger this aggressive, relapsing disorder.
Area of Science:
- Dermatology
- Surgical Oncology
Background:
- Autologous tissue transplantation techniques, primarily follicular unit transplantation (strip technique) and follicular unit extraction, are standard in hair transplantation (HT) surgery.
- Follicular unit extraction (FUE) is a common method for hair restoration.
Observation:
- A rare case of an aggressive, chronic, and relapsing hair transplantation sequence with an unusual clinical presentation was observed.
- The patient presented with fluctuating and communicating lesions in the occipital region, characteristic of a rare disorder known as PCAS (dissecting folliculitis or Hoffmann's disease).
Findings:
- The clinical presentation, course, and symptomatology strongly supported the hypothesis of PCAS.
- The mechanical extraction of follicular units during HT is speculated as a potential trigger for PCAS in this case.
Implications:
- This case highlights the need for further research into the etiology of PCAS, especially concerning its potential link to hair transplantation procedures.
- As hair transplantation increases, a potential rise in PCAS cases warrants increased clinical awareness and investigation.
