Sycosiform tinea barbae caused by trichophyton rubrum and its association with autoinoculation

Adult tinea capitis and tinea barbae in a tertiary Portuguese hospital: A 11‐year audit

“…A total of seven diagnoses of tinea barbae (Figure 1) monly observed when single-use razors were not yet available. 3,4 Albeit geographic differences have to be considered, and a 46.1% reduction in the number of diagnosed cases was observed in this study compared with a similar review realised in the past decade at another tertiary Portuguese hospital. 5 It is clear that facial overuse of high-strength topical steroids is a major issue perpetuating this disorder, which stands demonstrated both in our study and in others.…”

“…Remarkable improvements in lifestyle and hygiene habits have happened since then, and as demonstrated by this 11‐year survey, tinea barbae is nowadays an uncommon infection. For instance, tinea barbae was more commonly observed when single‐use razors were not yet available . Albeit geographic differences have to be considered, and a 46.1% reduction in the number of diagnosed cases was observed in this study compared with a similar review realised in the past decade at another tertiary Portuguese hospital .…”

Tinea barbae profunda caused by Trichophyton rubrum – an autoinoculation from a primary Tinea pedis

“…1,6,10 An autoinoculation of the beard area from an accompanying fungal infection with another localization, for example from Tinea pedis is described in such patients. 9,11,12 Years ago, autoinoculation was considered a quite rare phenomenon, but according to a study by Bonifaz et al 3 , physicians should consider autoinoculation as not so rare a method of fungal infection transmission.…”

Alopecia

“…If not timely treated, the alopecia can evolve to cicatricial alopecia. Kerion may be seen also in the beard area [68]. Other manifestation of highly inflammatory tinea is dissecting folliculitis-like, also called tinea abscedens, with fluctuating and communicating sinuses, and draining purulent secretion.…”

“…The differential diagnosis includes psoriasis (Figs. 20.51 and 20.52), bacterial infection, folliculitis decalvans, and dissecting cellulitis, all presenting with neutrophilic folliculitis, but with absence of fungal elements on histologic sections and culture [68,71]. Differential diagnosis also includes seborrheic dermatitis, alopecia areata, and trichotillomania.…”
