Costello syndrome (CS) is a multisystem congenital disorder characterized by coarse facial features, cardiac defects, intellectual disability, and predisposition to malignancies. Dermatologic findings can include cutaneous papillomas, skin redundancy, acanthosis nigricans, and keratosis pilaris. Palmoplantar keratoderma (PPK) is present in approximately 76% of patients with CS, with disabling functional consequences in severe cases. We report a case of CS with severe PPK that improved dramatically with systemic administration of acitretin 0.3 mg/kg/day.

Background: Poikiloderma with neutropenia is a rare genetic disorder primarily characterized by the presence of poikiloderma and congenital chronic neutropenia. Mutations in the C16orf57 gene, which encodes the USB1 protein, are implicated as the underlying cause of poikiloderma with neutropenia.
Case Presentation: Our patient, an 11-year-old Syrian male child who presented with poikiloderma, palmoplantar keratoderma, pachyonychia, recurrent infections, and neutropenia, is considered to be the first documented case in Syria.

Summary: Palmoplantar keratoderma (PPK), characterised by excessive epidermal thickening of the skin on the palms and/or plantar surfaces of the feet, can be hereditary or acquired. Here, we report a case of a 53-year-old woman with a history of sub-optimally controlled diabetes mellitus presenting with fevers and decreased Glasgow Coma Scale (GCS) to a tertiary hospital. She was diagnosed with diabetic ketoacidosis (DKA), with blood glucose at 40 mmol/L and ketones at 7 mmol/L, in the setting of a methicillin-sensitive Staphylococcus aureus necrotising soft tissue back infection.

Aim: Cutaneous adverse events (CAEs) after treatment with BRAF and MEK inhibitors in patients with melanoma remain incompletely characterized. To determine the association of BRAF and MEK inhibitor treatment with CAEs in patients with melanoma compared with BRAF inhibitor alone.
Method: PubMed, Cochrane, Embase and Web of Science were systematically searched for BRAF and MEK inhibitors from database inception through 10 May 2024.

Nagashima-type palmoplantar keratosis (NPPK) has been shown to represent a form of autosomal recessive palmoplantar keratosis due to biallelic pathological variants of SERPINB7, which encodes a serine protease inhibitor expressed in the epidermis. Approximately 10 years have elapsed since NPPK was demonstrated to be an independent genetic disease, and the most prevalent palmoplantar keratoderma (PPK) in East Asian countries due to a high prevalence of founder mutations in SERPINB7. Since then, it has become evident that biallelic pathological variants of SERPINA12, which encodes a serine protease inhibitor expressed in the epidermis, can also manifest symptoms analogous to those of NPPK.
