The document presents two cases of Tinea Capitis, a fungal infection of the scalp. The first case involves W. P., a 3½-year-old white boy, who experienced patchy hair loss and was treated with a 5% iodine solution. Initially, no fluorescence was detected under Wood's filter, but fluorescent hair was later observed, indicating resistance to treatment. The second case involves C. D., an 8-year-old Negro boy, who also had patchy hair loss. His scalp showed many fluorescent areas typical of ringworm, and a culture confirmed Microsporon audouini. He was successfully treated with a 5% iodine solution.
