Diagnosis: Tinea Corporis / Dermatophytosis
Comments: This 7-year-old boy had multiple widespread annular plaques
ranging from 1-5 cm in diameter. These lesions had been progressing for
6 weeks. His mother had 4 similar plaques on her left arm for 2 weeks. A
potassium hydroxide preparation obtained from the scaly border on one of
the mother's lesions was loaded with branching hyphae. The boy was treated
with oral griseofulvin, and his mother cleared with a topical antifungal
cream. Just before the eruption began the family purchased pet white rats,
and both were noted to have itchy scaly patches.
