Summary
Acute telogen effluvium can affect the donor area after hair transplantation, presenting with specific trichoscopic findings. This condition is typically self-resolving, and treatment focuses on symptom management.
Area of Science:
- Dermatology
- Trichology
- Hair Restoration Surgery
Background:
- Telogen effluvium is a non-scarring alopecia defined by increased hair shedding.
- It is often triggered by mechanical or inflammatory factors.
- Acute telogen effluvium is frequently observed in the recipient area post-hair transplantation.
Purpose of the Study:
- To report a case of acute telogen effluvium in the donor region following follicular unit extraction.
- To describe the characteristic trichoscopic findings associated with this condition in the donor area.
- To highlight the diagnostic utility of trichoscopy in managing hair shedding post-transplantation.
Main Methods:
- A case report of a 27-year-old male patient who developed itchy alopecic patches in the occipital region six weeks after follicular unit extraction.
- Clinical examination and trichoscopy were performed.
- Treatment involved topical betamethasone lotion for pruritus.
Main Results:
- Trichoscopy revealed empty follicular openings, short regrowing hairs, and coudability hairs.
- The patient experienced significant improvement with topical treatment within one month.
- The presentation in the donor area, unlike the typical recipient area, is noted as uncommon.
Conclusions:
- Acute telogen effluvium can manifest in the donor area after hair transplantation, a presentation not previously well-documented.
- Specific trichoscopic findings aid in diagnosing telogen effluvium and differentiating it from other alopecia types.
- Understanding the self-limiting nature of telogen effluvium allows for patient reassurance and appropriate management.
