Trichophyton violaceum: a rare isolate in 18-day-old neonate

Tinea faciei in a newborn due to Trichophyton tonsurans

We report here the first case of neonatal tinea faciei caused by Trichophyton tonsurans in mainland China. The mother of the infant had tinea corpris and tinea capitis while the father had tinea incongnito. The infections in the parents were mycologically confirmed to be due to Trichophyton tonsurans. Ttinea faciei in the infant was cured after two-week topical use of amorolfine cream. The mother ceased breastfeeding and took oral terbinafine for 4 weeks. No recurrence was observed in the infant during 12 months of follow-up.

Annular, erythematous skin lesions in a neonate

A 7-day-old premature female infant presented with rapidly progressive, erythematous, annular skin lesions from the 5^th day of life. She was diagnosed provisionally as a case of neonatal lupus erythematosus and was investigated accordingly. Histopathological examination of the skin biopsy specimen revealed presence of hyphae of dermatophytes in the stratum corneum, and the diagnosis was changed to tinea corporis. Differential diagnosis of the annular erythema of infancy has been discussed and the importance of scraping a scaly lesion for KOH preparation in the diagnostic work-up of such a patient has been highlighted.
