Naegeli syndrome in Adult
Reticulate hyperpigmentation of the trunk, neck, and axilla often occur within the first 2 years life with gradual resolution into late life. Patients have palmoplantar keratoderma, which, in turn, causes loss of dermatoglyphics. Teeth can have an abnormal shape in addition to enamel defects. Extensive dental work at a young age is often required, and this offers a key diagnostic clue. Nails can be brittle or malaligned. Hair is often normal, which can be a key distinguishing feature from other ectodermal dysplasias.
Hypohidrosis or anhidrosis often manifests as heat intolerance in childhood and is the primary cause of morbidity in this condition.
