  Introduction Top

Though tinea capitis is common in children, dermatophytic skin infections in infancy are uncommonly reported.[1][2][3] We reported infantile T. tonsurans infection observed by us.

  Case Report Top

A 14-day-old baby boy was brought for skin lesions on the forehead and left arm present for past 2 days. It was a full term, first child in the family, born through a normal vaginal delivery in our hospital. There was no history of similar lesions in the parents. There were no pets in the house. There was no history of any local application or contact with soil.

Cutaneous examination revealed a well defined mildly erythematous, raised, scaly almost circular plaque about 2.5 cms in diameter on forehead [Figure - 1]. The margin of the lesion on left forearm. Nails and scalp were normal. The systemic examination was noncontributory.

KOH examination from the patches revealed branching hyphae and culture on Sabourauds agar grew powdery, flat whitish colony. The colony later become velvety and yellowish, showing folds and a small depression in the centre with deep fissures and an umbo. Addition of thiamine accelerated the growth and microconidia and macroconidia were observed confirming T. tonsurans. Hair baiting did not grow fungus from soil of the house.

The lesions cleared after using 2% miconazole nitrate cream for the two weeks.

  Discussion Top

Reports of dermatophytic infections in the first two weeks of life are scanty. However, T. tonsurans,[1] T. mentagrophytes[2] and T. violaceum[3] infections startings at 9 days, 2 days and 6 days have been reported from our hospital.

Singh[4] reported a short incubation period of 5 days in experimental T. rubrum infection. Similarly, sloper[5] reported an incubations period of 2 days in experimental Epidermophyton floccosum, 3 days in T. rubrum and 2-7 days in T. mentagrophytes infection.

In a study from an urban paediatric clinic, Sharma et al[6] described an asymptomatic carrier state in young black children with T. tonsurans infection. The source of infection in the present case is unknown. A similar asymptomatic carrier state, if existing in people handling the child could be responsible for transmission.
