TLDR Itraconazole is effective for treating scalp ringworm, and a Wood's lamp is a useful diagnostic tool.

A 28-year-old female experienced rapidly progressive scaly patches on her scalp with hair loss, diagnosed as tinea capitis, likely due to her new cat. Diagnosis was confirmed using a Wood's lamp, which showed bright blue-green fluorescence, indicating infection by Microsporum canis. The patient was successfully treated with oral itraconazole and 2% ketoconazole shampoo, resolving symptoms after 8 weeks. The study highlights the effectiveness of itraconazole over terbinafine for treating tinea capitis and emphasizes the Wood's lamp as a cost-effective diagnostic tool.
