We report the largest study of TC in Spain. Our results were very similar to those in other national studies, noting a predominance of non-inflammatory cases of TC caused by zoophilic dermatophytes. Although the species of the causal dermatophytes have not varied substantially in this period, the increasing number of immigrants may lead to a change in the aetiology of TC in the future. The number of cases referred to the dermatology department who have already been treated shows a lack of communication between primary care and dermatology.
The incidence of tinea incognito (TI) appears to have increased over recent years, although no large series of cases has been reported in children. The aim of this study was to analyse the main epidemiological, clinical and microbiological characteristics of TI diagnosed in children in comparison with other tineas. We undertook a retrospective study of 818 tineas diagnosed in children in a referral hospital between 1977 and 2006, concentrating on TI. Of the 54 TI diagnosed, 85% were in the last 15 years. Most children were older than 9 years of age. The most usual clinical forms were tinea corporis (46.3%) and tinea faciei (38.9%). Topical steroids alone had been used to treat 68.5% of the cases. Direct examination was positive in 91.5% of the cases examined. Culture was positive in 85.2% of cases. The most frequently isolated dermatophyte was Trichophyton mentagrophytes (44.4%). This is the largest case series of childhood TI reported to date. TI has increased over recent years and important differences were found between these TI and the other tineas in children over the same period.
Tinea faciei (TF) is a common clinical form of tinea in children that is frequently misdiagnosed and treated with corticosteroids. No large case series of TF focusing on children have been published. The aim of this study was to analyze the main epidemiologic, clinical, and microbiologic features of TF in children over a period of 30 years and compare these features with those of other tineas. We undertook a retrospective study of 818 cases of tinea in children at a referral hospital in southern Spain, diagnosed between 1977 and 2006, concentrating for this study on TF. Of the 73 cases of TF diagnosed, 50.7% were in girls. Most children (46.6%) were 4 to 9 years old. At the time of diagnosis, 29.2% of the cases had been treated with topical steroids. The most frequently isolated dermatophyte was Trichophyton mentagrophytes, which was isolated significantly more frequently in TF than in the other tineas. Cases of TF in children were not extremely unusual, emphasizing that TF must be considered in children with inflammatory facial eruptions. This consideration and the more-frequent use of mycologic tests can help achieve the correct diagnosis, when present.
We report the case of a 5-year-old boy who had a temporary dragon-shaped henna pseudotattoo, reinforced 4 days later. Two weeks later, as the pseudotattoo began to disappear, hypertrichosis developed in the area corresponding to the previous psuedotattoo. Skin biopsy showed an increase in vellus hair follicles, with slight peripheral fibrosis. After 4 months, the hypertrichosis resolved spontaneously.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
