Conversely, if a nonfungal lesion is treated with an antifungal cream, the lesion will likely not improve or will worsen. In addition to the common distal subungual form, which is characterized by thickened, brittle, discolored nails (Figure 5), onychomycosis may present with an uncommon proximal subungual form, which should raise suspicion of immunocompromise, and a white superficial form, which is more common in children than adults24 (Figure 6). The child with tinea capitis will generally have cervical and suboccipital lymphadenopathy, and the physician may need to broaden the differential diagnosis if lymphadenopathy is absent.7 However, lymphadenopathy can also occur in nonfungal scalp disease, and the absence of lymphadenopathy in an otherwise typical presentation should not delay aggressive treatment for tinea capitis.9.
