Final comment: Folliculitis refers to a heterogeneous group of conditions that may occur due to infection or irritation or as a manifestation of inflammatory skin disease. Different types of folliculitis should be properly diagnosed to clarify preventive and therapeutic recommendations.
Acne, rosacea, and similar disorders
Published in Rashmi Sarkar, Anupam Das, Sumit Sethi, Concise Dermatology, 2021
Histologically, the essential features are those of a folliculitis with considerable inflammation. The exact histological picture depends on the stage reached at the time of biopsy. Usually, it is possible to make out the remnants of a ruptured follicle. In the earliest stages, a follicular plug of the horn (comedone) can be identified. Later, fragments of horn appear to have provoked a violent mixed inflammatory reaction with many polymorphs and, in places, a granulomatous reaction with many giant cells and histiocytes (Figure 10.16). In older lesions, fibrous tissue is deposited, indicating scar formation.

Design of lower limb prosthetic sockets: a review

The temperature of the prosthetic socket is rising in the full-contact prosthetic sockets and other prosthetic sockets for large contact areas with skin due to the close fit. The rising temperature makes the skin sweat more than usual, and the sweat cannot evaporate freely in a substantial area. The increased humidity may occur intertriginous dermatitis, evoking infections with dermatophytes and yeasts of the groin. The increased humidity may cause slippage and lead to skin problem. In addition, bacterial infections occur, especially with staphylococcus aureus leading to folliculitis, furunculosis (or boils), cellulitis, pyoderma, and hidradenitis [16]. Sensitization from chemical compounds of the socket or liner also may lead to allergic contact dermatitis and irritant dermatitis and atopic eczema (Figure 2) [20]. Preexisting skin diseases (e.g. psoriasis or acne) may be elicited by the use of sockets.

Loganathan et al. performed a retrospective analysis including 73 male patients with androgenetic alopecia treated with hair restoration therapy including FUT, follicular unit extraction (FUE), and body hair transplantation. Complications in hair restoration therapy, the most severe of which is death in inexperienced centers, are relatively few and rare compared with other aesthetic surgical procedures but are still prevalent. The most common adverse event was postoperative edema, occurring in 42.47% of reviewed patients. Moreover, folliculitis is a common complication of hair transplantation [30,31]. Patients (10.96%) in Loganathan and colleagues’ study developed bacterial folliculitis in the donor area up to eight months after surgery. Sterile folliculitis weeks or months after transplantation is commonly found as well, occurring in 23.29% of Loganathan et al.’s patients. In a case report by Yang following a 38-year-old man with Norwood type V alopecia receiving hair transplantation, in addition to mild postoperative pain and discomfort, erythematous folliculitis due to a buried graft was documented [32].

In the current work, folliculitis was reported in 10% of patients, who were treated and could continue the therapy. Our results were in agreement with previous studies who reported folliculitis, acneform facial eruption, telangiectasia and mild local atrophy in one patient (22,32,34). In addition Kuldeep et al. (2011) (31) reported 10.4% of patients complaining of itching after treatment with betamethasone valerate foam, furthermore, Sardesai et al. (2012) (12) not reported any side effects. Relapse was reported in 20% of patients in eighth and tenth weeks of follow-up period after stoppage of betamethasone valerate and no regrowth reported during the follow-up period. Our results were consistent with many studies (2,16).
