History:

 An 8-year-old boy presented with multiple scaly patches with hair loss on the scalp of two months duration. O/E; the hairs in the involved areas were lusterless and easily and painlessly pulled-out of their follicles. It was diagnosed as gray-patch tinea capitis on clinical background and was given oral griseofulvin 20 mg per day in 2 divided doses taken with fatty meals. One month later, a dramatic response was seen and the patient was advised to continue his treatment for further 2 weeks.
