Differential Diagnosis

History: Tinea capitis is a common problem among children.However,it is rarely seen in adult patients as it is traditionally thought that sebum due to its acidic nature may have a protective role against dermatophyte infection (Fungicidal effect). This 55-year-old man has had a slightly erythematous patch with raised well-demarcated and active border involving the neck and extending into the lower part of the occipital scalp causing localized hair loss. On examination, the patch was slightly scaly and the hair was easily and painlessly pulled-off. Hair examination under light microscope yielded positive fungal hyphae and spores.
