To the Editor
Tinea versicolor is a chronic superficial mycosis caused by Malassezia furfur, a lipophilic yeast which is a saprophyte of the normal skin in 92% of people.  Factors responsible for the overgrowth of the yeast and conversion to a predominantly parasitic mycelial morphology associated with clinical disease are a warm and humid environment, genetically inherited predisposition, occurrence near puberty, immunosuppression, malnutrition, pregnancy, Cushing's disease, use of oral contraceptives, excessive oily skin and hyperhidrosis ,
Recently a 6-year-old healthy male child was referred to us with asymptomatic hypopigmented scaly macules of 3 weeks duration, symmetrically placed over dorsal surface of hands and feet. Relevant family history was negative. General physical and systemic examination revealed no other abnormalities. KOH mount with methylene blue stain from the lesions showed typical "meatball and spaghetti" appearance of yeast and hyphae while other laboratory investigations showed no evidence of immunosuppression.
Patient was treated with twice daily local application of ciclopiroxolamine solution which provided clinical and mycological cure in 4 weeks.
The observations in this child have left many unanswered questions regarding pathogenesis of tinea versicolor. It is interesting to note that sebaceous glands are only sparsely located on the dorsal surface of hands and feet.  Also sebaceous activity is at its minimum in early childhood.  Absence of family history in this child excludes a genetic predisposition for tinea versicolor. This child also showed no evidence of malnutrition or nonspecific immunosuppression. These observations suggest that there may be other factors in the pathogenesis of tinea versicolor which have to be looked for.
