    Title translation Infectious genital lesions.
    Abstract External genital infections are multiple, possibly linked to viral, bacterial, mycosic, or parasitic infections. Viral and bacterial infections often integrate within the framework of Sexually Transmitted Diseases (STD/STI) and can be associated with a context of immunosuppression. Skin or mucosae damage is often isolated. Their diagnosis is often referred to clinically, and confirmed by local samples without the need for biopsy. Histological examination is indicated in unusual clinical cases or in cases of persistent lesions or atypical appearance or pseudotumoral, posing a challenge for clinical differential diagnosis. In these cases, the morphological analysis can be supplemented by special colorations, immunological techniques or even molecular analysis allowing in some cases the detection and identification of infectious agents. This chapter will integrate external genital infections of viral, bacterial and parasitic origin where histological analysis is the diagnostic element of orientation.

    Abstract 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.

    Abstract Background: Follicular hyperkeratosis along with hyperplasia of the follicular and interfollicular epithelia are major histopathological characteristics of hidradenitis suppurativa (HS). The presence of an occasional thickening of lesional skin in some folliculitis decalvans (FD) patients and histological similarities between FD and HS led us to look for epidermal hyperplasia and follicular hyperkeratosis in FD patients.
    Patients and method: We performed a retrospective histological analysis of 26 patients with FD.
    Objective: We sought to find out whether the presence of hyperplasia of the interfollicular epidermis and of the follicular epithelia could be verified in FD, with reference to the work of von Laffert et al. concerning HS.
    Results: The main quantitative and qualitative data were: follicular hyperkeratosis (77%), hyperplasia of the interfollicular epidermis (92%) with a psoriasiform aspect (88%), atrophy of the follicular epithelia (85%), plasma cells in infiltrate (92%) in large quantities (42%), follicular microcysts (60%), atrophy of the sebaceous glands (85%) and polytrichia (54%).
    Conclusion: Epidermal hyperplasia, sometimes psoriasiform and follicular microcysts, are significant histological signs of FD, which have been ignored until now although they seem very common.

    Abstract Background: Frontal fibrosing alopecia (FFA) differs from lichen planopilaris (LPP) in many clinical aspects, but histology fails to distinguish between these entities. Direct immunofluorescence (DIF) is a diagnostic technique used for autoimmune diseases, including those affecting skin and hair.
    Objective: To characterize DIF patterns in patients with FFA.
    Method: Data was collected retrospectively from FFA cases presenting to the Centre de Santé Sabouraud Hair Clinic in Paris from November 2013 to November 2014.
    Results: Of 149 patients with FFA, 44 cases underwent DIF. Thirteen cases showed positive results with DIF. Patterns characteristic of LPP and lupus erythematosus were observed, with nearly half showing nonspecific staining.
    Conclusion: DIF patterns in patients with FFA were variable. This diagnostic technique should be used with caution in cases of cicatricial alopecia, particularly FFA.
