Nagashima-type palmoplantar keratoderma (NPPK) is an autosomal recessive form of diffuse palmoplantar keratoderma (PPK) characterized by thickening and redness of palms and/or soles. In this report, we describe a female patient of Korean descent who had clinical remission of her adult-onset NPPK. To our knowledge, she is the first reported heterozygous SERBINB7 mutation carrier to present with classic NPPK who achieved spontaneous clinical remission.

Acquired palmoplantar keratoderma (PPK) is a non-hereditary hyperkeratosis of the palms and soles that is caused by various factors, including chemotherapeutic agents. The purpose of this case report is to present a rare case of acquired PPK caused by the chemotherapeutic agent capecitabine. A 54-year-old female complained of painful erythematous plaques on her palms and soles with history of consuming capecitabine.

Article Synopsis
  • Pachyonychia congenita (PC) is a rare genetic disorder characterized by abnormal skin cornification and is inherited in a dominant fashion.
  • It has attracted significant research attention over the past 20 years, largely due to efforts from the Pachyonychia Congenita Project, a patient support organization.
  • The article discusses ongoing research in PC, potential benefits for managing other diseases, and challenges facing these initiatives.

Article Synopsis
  • Pityriasis rubra pilaris (PRP) is a rare and challenging skin disorder marked by specific skin lesions, and while some cases resolve on their own, treatment options can be limited.
  • A case study of a 71-year-old patient with stubborn PRP demonstrated significant improvement with a tailored adalimumab treatment plan, adjusting the medication intervals for better efficacy.
  • The addition of montelukast—known for its role in the condition's mechanism—helped maintain treatment success, suggesting that further research is needed to explore these optimized treatment strategies.

Article Synopsis
  • The Pachyonychia Congenita Project (PC Project) is a global advocacy group focused on helping individuals with pachyonychia congenita, a painful skin disorder caused by mutations in specific keratin genes.
  • The organization runs two key programs: the International Pachyonychia Congenita Consortium (IPCC) and the International Pachyonychia Congenita Research Registry (IPCRR), which provide support and diagnostic services for patients.
  • The PC Project aims to connect patients, researchers, medical professionals, and industry partners to promote research and development for effective treatments and potential cures for pachyonychia congenita.

Article Synopsis
  • A cutaneous horn, or cornu cutaneum, is a growth made of keratinizing skin cells that often develops over underlying skin lesions such as benign and malignant tumors, infections, or other skin conditions.
  • The text describes two cases: a 22-year-old woman with a cutaneous horn linked to a stubborn wart on her toe, and a 57-year-old man with a horn associated with inverted follicular keratosis on his lip.
  • The most common conditions related to cutaneous horns are actinic keratosis, squamous cell carcinoma, and seborrheic keratosis, with several benign and malignant tumors associated with these skin growths.

Spiny keratoderma is a rare skin condition that presents on the palmar and plantar surfaces of the hands and/or feet. This condition is difficult to appreciate under ambient lighting but can be both physically and emotionally distressing to patients. Furthermore, because of the association with various neoplasms and systemic diseases, timely diagnosis and appropriate follow-up is of importance.

A machine learning approach to predict the glaucoma filtration surgery outcome.

Sci Rep

October 2023

Department of Medicine and Ageing Science, Ophthalmology Clinic, University "G. D'Annunzio" of Chieti-Pescara, Via Dei Vestini, 66100, Chieti, CH, Italy.

This study aimed at predicting the filtration surgery (FS) outcome using a machine learning (ML) approach. 102 glaucomatous patients undergoing FS were enrolled and underwent ocular surface clinical tests (OSCTs), determination of surgical site-related biometric parameters (SSPs) and conjunctival vascularization. Break-up-time, Schirmer test I, corneal fluorescein staining, Meibomian gland expressibility; conjunctival hyperemia, upper bulbar conjunctiva area of exposure, limbus to superior eyelid distance; and conjunctival epithelial and stromal (CET, CST) thickness and reflectivity (ECR, SCR) at AS-OCT were considered.

Clouston Syndrome: Report of a Jordanian Family with GJB6 Gene Mutation.

Case Rep Dermatol Med

October 2023

Department of Dermatology, School of Medicine, University of Jordan, Amman, Jordan.

Ectodermal dysplasias (ED) encompass a collection of conditions wherein the development of two or more structures derived from the ectoderm exhibits abnormal patterns. One example of such a rarity within the spectrum of ectodermal dysplasias is hidrotic ectodermal dysplasia, also known as Clouston syndrome. This particular variant is distinguished by a triad of clinical characteristics, which encompass partial-to-complete alopecia, nail dystrophy, and palmoplantar hyperkeratosis.

Article Synopsis
  • Hereditary palmoplantar keratoderma is a rare genetic skin condition marked by thickening of the skin on the palms and soles, influenced by various genetic mutations affecting keratin-related proteins.
  • A case involving a 29-year-old HIV-positive African woman showcases the complexity of this condition, with her symptoms including painful constriction bands and skin thickening, which led to complications like toe amputation.
  • Genetic testing revealed uncertain findings related to specific genes, highlighting the challenges in diagnosis and emphasizing the need for early detection and proper treatment to improve patient quality of life.

Centre for Cell Biology and Cutaneous Research, Blizard Institute, The Faculty of Medicine and Dentistry, Queen Mary University of London, London, United Kingdom.

Pachyonychia congenita (PC) is a rare, autosomal dominant inherited disorder of keratinization that is characterized by a triad of focal palmoplantar keratoderma, plantar pain, and hypertrophic nail dystrophy. It can be debilitating, causing significantly impaired mobility. PC is diagnosed clinically alongside identification of a heterozygous pathogenic mutation in one of five keratin genes: KRT6A, KRT6B, KRT6C, KRT16, or KRT17.

  • Ichthyoses are genetic skin disorders that cause varying degrees of scaling and redness, often linked to palmoplantar keratoderma.
  • Different forms of ichthyosis are classified based on genetic mutations or clinical characteristics, with some symptoms overlapping between conditions.
  • A study found that two family members, presenting with symptoms similar to erythrokeratodermia variabilis, had mutations in the ABCA12 gene associated with a milder form of ichthyosis, leading to a partial loss of skin barrier function.
