Overview: Dermatophytic folliculitis typically presents with follicular pustules on the surface of a red, firm, exudative, and extending plaque. It can develop in association with tinea barbae, tinea capitis, or tinea corporis. Lesions of folliculitis in tinea barbae involve the beard or mustache area. Trichophytic (Majocchi) granuloma classically occurs in women shaving their legs or when tinea corporis is first treated with topical corticosteroids. Malassezia (Pityrosporum) folliculitis commonly affects young males and presents with follicular papules and pustules involving the trunk, shoulders, neck, or extensor aspects of the arms. Candidal folliculitis appears as satellite pustules around the flexural lesions of candidiasis, especially in diabetics.

Tinea barbae is a rare infection of the beard area. It most often occurs in men who are in close contact with farm animals [4]. The fungi infect the hair shaft, forming either nodular, boggy, exudative lesions, or crusted patches with associated partial alopecia. Bacterial folliculitis and ingrown hairs may complicate the condition. Tinea barbae may be confused with folliculitis, sporotrichosis, candidiasis, pseudofolliculitis barbae, contact dermatitis, herpes labialis, acne, syphilis, and even malignant lymphoma.

Tinea barbae is defined as dermatophytosis of the beard area in men. Historically, it is linked to contaminated razors at barbershops, and it has become much less common in the last few decades. The two most common organisms responsible for tinea barbae, T. mentagrophytes and T. versicolor, produce an inflammatory reaction associated with elevated nodules, draining pustules, and sinus tracts. The hair in affected areas may be distorted or even absent. The chin and neck are usually involved and the upper lip is rarely affected. Untreated, it can result in significant scar formation. Clinically, tinea barbae can be easily confused with bacterial folliculitis, acne vulgaris, and contact dermatitis.

Dermatophytes are superficial cutaneous mycoses involving keratinised tissues, such as stratum corneum, hair or nails. However, sometimes they spread to deeper strata, leading to cases such as Majocchi granuloma, in which deeper regions of the hair follicles, the dermis and even the hypodermis are affected (Coelho et al. 2009). Although, Trichophyton rubrum is the most frequent species, T. mentagrophytes, a zoophilic species which generates important inflammatory reactions, may also be involved (Chang et al. 2005; Bakardzhiev et al. 2016). Trichophytonmentagrophytes (previously T. mentagrophytes var. mentagrophytes) may be associated with dermatophytid reaction. It causes inflammatory tinea pedis, cruris and tinea barbae and is associated with the exposure to small mammals. On the other hand, T. interdigitale, an anthropophilic dermatophyte (previously T. mentagrophytes var. interdigitale) is mainly responsible for the interdigital, tinea pedis and sometimes, tinea cruris and onychomycosis.
