ABSTRACT
Tinea capitis (TC) is still a frequent dermatophytosis in France, both autochthonous and imported. A nationwide retrospective survey was performed and a total of 4395 TC cases were recorded within 36 French mycology laboratories during a 6-year period. TC is a disease that occurs in childhood with 85% of the cases occurring before 10 years old and 94% before the age of 15. Anthropophilic origin was predominant with 779 cases of Trichophyton tonsurans (32.6%), 738 cases of Trichophyton soudanense/T. violaceum (31%), and 445 cases of Microsporum audouinii (19.2%). Of note, T. tonsurans represents more than 80% of the cases in the French West Indies (Martinique and Guadeloupe). By contrast, zoophilic species were less prevalent with mainly M. canis (10.3%) confirming the shift from zoophilic to anthropophilic species observed in many centers during the last decades. During this survey, diagnosis methods were also collected. Most labs had a classical process for the diagnosis microscopic direct examination associated to cultures on Sabouraud and Sabouraud-cycloheximide media (incubated between 25 ± 5°C for at least 3 weeks) in all laboratories. Identification of the causal dermatophyte was performed by microscopic and macroscopic examination of the cultures in 100% of the labs, with various specific culture media available when fructification was insufficient (mainly malt or potato-dextrose agar, or Borelli medium). New techniques were also implemented with the introduction of MALDI-TOF mass spectrometry identification in more than two third of the labs, and molecular identification available if necessary in half of the labs.
A total of 4395 tinea capitis cases were recorded within 36 French mycology laboratories during a 6-year period. An anthropophilic origin was predominant with 33%, 31%, and 18.8% of cases due to Trichophyton tonsurans, T. soudanense/T. violaceum, and Microsporum audouinii, respectively.
