A psoríase possui diversas formas de apresentações clínicas. Lesões hiperceratósicas podem ser observadas e verificam-se na literatura diversas denominações para essas lesões, como elefanthine, rupióide, ostrácea e pseudocórnea. É interessante notar que duas dessas denominações se remetem à semelhança com conchas encontradas nos estudos de conquiliologia: rupióide e ostrácea. Os autores comparam os aspectos morfológicos das variantes da psoríase hiperceratósica com as conchas de diversas espécies de moluscos.

A male full‐term infant, who had been exclusively breast‐fed since birth, at 2 months of age developed an erythematous, scaling eruption involving the face (in a periorificial distribution, i.e. mouth, nose, ears, and eyes), hands, and feet, which did not respond to treatment with topical corticosteroids and oral antimicrobials. He was first seen at our institution at 5 months of age (Figs 1 and 2). He had been irritable for the last 2 weeks, but had no diarrhea, alopecia, or anogenital lesions. A clinical diagnosis of acrodermatitis enteropathica was confirmed with a serum zinc level of 41.2 µg/dL (normal, 70–120 µg/dL). His mother had low–normal serum (70.5 µg/dL; normal, 70–120 µg/dL) and normal milk (0.43 µg/mL; normal, 0.2–0.72 µg/mL) zinc concentrations. Within 7 days of starting therapy with zinc sulfate, 10 mg/kg/day, all cutaneous lesions had resolved (Fig. 3). 1 Infant at 5 months of age showing an erythematous, scaling eruption involving the face (periorificial distribution, i.e. mouth, nose, and eyes) and hands 2 Infant with dermatophytosis‐like lesions 3 Infant at 6 months of age after starting oral zinc supplementation.

The ketogenic diet was effective and safe in three out of six patients with intractable epilepsy. Neutropenia was the most common complication.
