To the Editor.—
The onset in children of subcorneal pustular dermatosis with systemic reactions and fever is similar to the respiratory infections and chronic disease which may precede the disease in adults. The family history of psoriasis (case 2) is thought to be insignificant at this stage of the disease, since histologically and clinically psoriasis is not present. Lesions of the face are most likely a particular characteristic of the disease in children and not in the adult with subcorneal pustular dermatosis or in psoriasis. The lesions in the mouth of patient 1 were a part of the patient's tonsillitis and toxic condition, while those of patient 2 were transitory benign plaques or changes characteristic of a geographic tongue and not a manifestation of the existing disease.On histologic examination, there was an absence of spongiform pustules, microabscesses, congestion of papillae, and elongation of rete ridges that occur in psoriasis
