International Journal of Dermatology 2005, 44 , 765-768 765A 26-year-old woman with no family history of dermatophytosis presented with pruritic erythema on the right palm ( Fig. 1) in November 2002, 1 month after first noticing it. She had no lesions on the soles, toe webs, left palm, or nails. The erythema had been treated with topical steroids for 4 weeks, but had continued to expand. The erythema measured 42 mm × 36 mm, and was hyperemic and infiltrated unevenly. Its center showed no signs of healing, its periphery exhibited small vesicles, and its margin showed scales. On the scales, fungal hyphae and chains of arthroconidia were revealed by direct KOH test. The erythema was diagnosed as tinea manuum and was treated with topical terbinafine once daily. After several days of treatment, the erythema flared up and red papuloerythemas appeared on the back of both hands and on both forearms.Ten days after the first visit, the patient returned to our clinic for the treatment of newly developed eruptions. A trichophytin skin test produced an infiltrated erythema measuring 21 mm × 18 mm, confirming that the newly developed eruptions and exacerbated erythema on the right palm were due to a trichophytid reaction. Topical terbinafine was continued for the palm and fluocinolone acetonide ointment was applied on the newly developed eruptions on the arms from day 10 after the first visit. All the inflammatory eruptions subsided after 4 weeks of treatment and direct KOH test results were negative.The suspected cause of tinea manuum was the patient's pet female four-toed hedgehog ( Atelerix albiventris ) which she had kept for 4 years (Fig. 2). When she bought it from a local pet shop, it had desquamation on its body, but no lesions with loss of hair or quill and no dermatitis.The scaling decreased gradually with treatment given by a veterinarian.Three isolates of dermatophytes were obtained from the scale on the woman's palm (KMU 4455), scale removed from the hedgehog (KMU 4459-1), and a fallen-out quill (KMU 4459-2).KMU 4455 grew rapidly with an ivory-white and lightly powdery surface, and with concentric ripples at the periphery. The center of the colonies was fluffy and elevated slightly, with a yellow pigment beneath (Fig. 3). The strains from the hedgehog were morphologically similar to each other, and their colonies grew more slowly and had a more powdery texture than those of KMU 4455. KMU 4459-1 and KMU 4459-2 gave a positive urease test result, whereas KMU 4455 gave negative results even at day 7 of incubation. The microscopic findings of the three isolates were almost the same (Fig. 4). Numerous teardrop-shaped microconidia were produced along the sides of the rectangle of mycelium. Spherical microconidia clustered in some parts and some club-shaped, 2 -6-roomed macroconidia were observed. There were some poorly developed macroconidia and some elongated microconidia which were so large that they were intermediate in size between normal microconidia and macroconidia. There was no spiral body.The isolates were mate...

Trichophyton mentagrophytes var. erinacei is the most common dermatophyte isolated in hedgehogs. Usually T. mentagrophytes var. erinacei infection manifests as an extremely inflammatory and pruritic eruption that is confined to the site of contact with the hedgehog. Although the identification of T. mentagrophytes by traditional methods is possible, identification by ITS region analysis is a fast, simple, and increasingly available method. The increasing frequency of the practice of keeping exotic animals as pets has resulted in the emergence of several zoonotic diseases that can potentially be transmitted to humans.

“…We could find only one report of tinea barbae occurring due to T. erinacei, and like our case, there was also direct contact spread to the patient's partner. 10 With hedgehogs becoming more popular as domestic pets, it is possible that an increasing number of T. erinacei fungal infections in their human owners may be seen. Physicians should therefore be aware of this unusual zoophilic dermatophytic infection, and take a detailed contact history.…”

Trichophyton erinaceikerion barbae from a hedgehog with direct osculatory transfer to another person

et al. 2013

We describe a case of kerion tinea barbae infection due to Trichophyton erinacei in a 37-year-old man. The infection had also been transferred to his partner by direct contact from kissing. T. erinacei is a zoophilic dermatophyte occasionally harboured by the hedgehog (Erinaceus europaeus). There are few reports of human infection in the literature, and it rarely causes a kerion. There is only one previous report of tinea barbae occurrence due to T. erinacei. This case highlights the possibility of one of the more unusual fungal infections that can be acquired in the UK, and highlights the necessity of asking specific questions to identify possible sources of infection.
