Tinea capitis is a type of fungal infection on the scalp, which primarily affects children aged 3вЂ“7В years old. Her toenails finally got normal gradually in the following 4В months with the continuing treatment of oral terbinafine. 4c, d) and to turn negative mycologically, but 8В weeks for the culture of scrapings and 12В weeks for the result of WoodвЂ™s lamp to turn negative, respectively. As for her scalp lesion, it took her 6В weeks to be cleared clinically (Fig. Two weeks later, the rashes on trunk and extremities cleared both clinically and mycologically (Fig. She was treated with oral terbinafine 250В mg daily, topical bifonazole solution and ketoconazole cream on her body twice per day. e Microscopic examination (Г—вЂ‰40) showing septate hyphae and typical macroconidia of M.canisД¬onsidering the coexistence of tinea capitis, extensive tinea corporis, tinea pedis and onychomycosis, the patient was diagnosed as tinea capitis caused by M.canis with extensive dermatophyte infection. The cottony colony is white from the front and orange from the reverse. c, d Gross morphology of M.canis on Sabouraud dextrose agar cultured from the hair of both the patient and the cat (after 10-day incubation at 28В вЊ). There was no associated lymphadenopathy.ДЄ, b Ectothrix hyphae and spores revealed in the direct KOH examination and fluorescence stain. All of her toenails revealed discoloration and subungual hyperkeratosis. These patches showed elevated and well-demarcated borders, with considerable white superficial scales.

Multiple large erythematous patches could be seen on her face, neck, bilateral ears, trunk, extremities, as well as skin folds including perineum, groin and axillae (Fig. Morse code-like hairs, white sheaths and short broken hairs could all be seen under a dermoscope (Fig. Bright-green fluorescence was prominent on her hair under WoodвЂ™s light illumination (Fig. Physical examination revealed multiple scaly erythematous patches on her scalp with thick greyish-yellow crusts and patches of alopecia with broken hair (Fig. She had been diagnosed with onychomycosis for 2В years without treatment.

Her fasting blood glucose was controlled within 6вЂ“7В mmol/L and postprandial blood glucose within 8вЂ“9В mmol/L with subcutaneous insulin. She had diabetes mellitus for nearly 5В years. She was diagnosed as seborrhoeic dermatitis and psoriasis previously and treated with compound econazole nitrate and triamcinolone acetonide cream without improvement. The rashes first involved her chest skin and then gradually spread to the whole trunk, scalp, groin and all extremities with severe pruritus and malaise. Terbinafine, griseofulvin and itroconazole have been reported to be effective drugs for the treatment of tinea capitis, and terbinafine can be considered as systemic treatment in elderly patients with comorbidities to reduce the drugвЂ“drug interaction.ДЄ 71-year-old woman presented with a six-month history of persistent scalp rashes together with generalized body skin lesions. Trichophyton violaceum is the most common dermatophyte species in most regions while adult tinea capitis caused by Microsporum canis is less common.

A thorough history (including the animal contacting history), physical examination and further mycological examinations are required for diagnosis. However, in some regions, the incidence of tinea capitis in immunocompetent adults is rising which requires the awareness of clinicians. Adult tinea capitis is often misdiagnosed due to its rarity and atypical presentation. Treatment with oral terbinafine was effective. Further microscopic examinations of her scalp, including direct KOH and fluorescence stain examination, fungal culture and polymerase chain reaction sequencing identification confirmed the diagnosis of tinea capitis caused by Microsporum canis.

Dermoscopic findings and manifestation under the WoodвЂ™s lamp favoured the diagnosis of tinea capitis. She adopted a stray cat before the disease onset. We report a case of an elderly woman with well-controlled diabetes mellitus presenting with a six-month history of erythema with yellow crusts on her scalp and extensive erythematous patches with scales on the body skin. Tinea capitis is a type of dermatophyte infection primarily affecting children.
