INTRODUCTION: Tinea capitis is common among schoolchildren in developing countries but underreported in Madagascar. We report the occurrence of an outbreak of gray patch tinea capitis due to Microsporum langeronii in a public primary school of Antananarivo, the capital city of Madagascar. METHODOLOGY: Forty-two children were included, 27 (64%) of them presenting with tinea capitis and 32 (76%) with Tinea corporis. Patients were treated with griseofulvin 500 mg and Povidone-iodine 4% and followed up for four weeks. RESULTS: Twenty-five (93%) of the 27 children with tinea capitis presented a gray patch as the main clinical feature. All these cases were fluorescent under Wood's UV light and positive in cultures for M. langeronii. All 27 children reported a contact with infected classmates, and 19 (70%) reported to have infected brothers and sisters at home. After four weeks of treatment, all patients recovered. CONCLUSION: Appropriate treatment and improved hygienic practices reduced the occurrence of tinea in the studied school and no more cases of tinea capitis or corporis occurred after the outbreak.
