Inflammatory complications after hair transplantation: Report of 10 cases.

BACKGROUND

Androgenetic alopecia (AGA) is a pathology involving the aesthetic prognosis. Hair transplantation is among best treatments. The principle of hair micro-grafts during AGA consists in taking hair from the non-androgen-dependent occipital area to transplant them with their root in the sparse androgen-dependent areas. Herein, we report 10 cases of the different types of post-transplant inflammatory complications.

MATERIALS AND METHODS

We included patients referred to our center by their dermatologists or hair transplant surgeons for inflammatory cicatricial alopecia or hair loss observed after the hair transplant.

RESULTS

Ten patients (eight men and two women) were included. These patients represented 0.08% of all consultations in our center. The indication for hair transplantation was AGA in all of our patients. The technique used for the transplant was follicular unit extraction (FUE) in seven cases and follicular unit transplantation (FUT) strip in three cases. None of the patients had pathology of the scalp or an inflammatory dermatosis before the operation. The inflammatory complications found were lichen planopilaris (LPP) in seven cases, erosive pustulosis of the scalp (EPS) in two cases, and superficial folliculitis (SF) in 1 case.

CONCLUSION

Our series highlight the rarity of inflammatory complications that occur after a hair transplant. We demonstrate through this work that a hair transplant can trigger inflammatory pathology a few months after the act. We show also, the importance of detecting the rough forms of lichen before an intervention, hence the interest of the systematic dermatoscopic examination during the preoperative consultation.
