Acrodermatitis enteropathica is a rare and distinct form of zinc deficiency with a requirement of life-long zinc supplementation and inherited in a recessive manner. Transient nutritional zinc deficiency is also a well known condition mimicking acrodermatitis enteropathica like skin changes in preterm and term infants who are generally breastfed with a low level of zinc containing milk. Here, a 4-month-old male, term and fully breastfed acrodermatitis enteropathica case without hypozincemia and with maternal milk of low zinc level is presented.

Acrodermatitis dysmetabolica: lessons from two pediatric cases.
J Pediatr Endocrinol Metab

Department of Pediatrics, Konya City Hospital, University of Health Sciences, Konya, Türkiye.
Objectives: Acrodermatitis dysmetabolica (AD) is a dermatologic manifestation associated with inherited metabolic disorders (IMDs), distinct from acrodermatitis enteropathica, which occurs solely due to zinc deficiency.
Case Presentation: This report presents two pediatric cases: a 30-month-old girl with maple syrup urine disease (MSUD) experiencing AD secondary to severe isoleucine deficiency due to a protein-restricted diet, showing improvement with dietary adjustments, and a 2.5-month-old boy infant with propionic acidemia (PA) who developed AD alongside septic shock, which progressed despite intervention.
Research progress on the molecular structure, function, and application in tumor therapy of zinc transporter ZIP4.

ZIP4, a pivotal member of the ZIP family, is the causative gene for the hereditary disorder AE (acrodermatitis enteropathica) in humans, and plays an essential role in regulating zinc ion balance within cells. While research on the molecular structure of ZIP4 continues, there remains a lack of full understanding regarding the stereo-structural conformation of ZIP4 molecules. Currently, there are two hypotheses concerning the transport of zinc ions into the cytoplasm by ZIP4, with some contradictions between experimental studies.

Acrodermatitis enteropathica (AE) can be caused by inherited or acquired zinc deficiency, among which site-specific skin lesions or even psoriasiform skin manifestations are present. Few cases exist in the literature involving the diagnosis and treatment of AE overlapped with psoriasiform lesions. In this case, we reported a teenage boy presented characteristic site-specific skin lesions of AE with low serum zinc level, subsequently progressed into generalized pustular psoriasiform manifestations under a genetic background, while a rapid recovery was observed after monotherapy of zinc supplementation.
