Clinical features and management of superficial fibromatoses.

J Dtsch Dermatol Ges 2019 Mar 13. Epub 2019 Mar 13.

Department of Dermatology and Allergy Biederstein, Technical University of Munich, Munich, Germany.

Fibromatoses are a group of benign connective tissue tumors characterized by the infiltrative, aggressive proliferation of well-differentiated fibroblasts, leading to frequent local recurrence. Within this heterogeneous disease group, superficial fibromatoses show slower growth and more benign infiltration of surrounding tissues than deep fibromatoses. Superficial fibromatoses relevant to dermatology include palmar, plantar, and penile fibromatosis, knuckle pads, pachydermodactyly and infantile digital fibromatosis. Read More

Genetic Analysis of KRT9 Gene Revealed Previously Known Mutations and Genotype-Phenotype Correlations in Epidermolytic Palmoplantar Keratoderma.

Front Genet 2018 7;9:645. Epub 2019 Jan 7.

Institute of Dermatology and Department of Dermatology of First Affiliated Hospital, Hefei, China.

Epidermolytic palmoplantar keratoderma (EPPK, OMIM 144200) is an autosomal dominant inherited disease, clinically characterized by diffuse yellowish thickening of the skin on the palms and soles, usually with erythematous borders developing during the first weeks or months after birth. Pathogenesis of EPPK is determined by mutations in the keratin gene (KRT9). Thirty three mutations in the KRT9 gene from 100 EPPK families have been identified. Read More

Miscellaneous skin disease and the metabolic syndrome.

Clin Dermatol 2018 Jan - Feb;36(1):94-100. Epub 2017 Sep 8.

Department of Dermatology, Istanbul Medeniyet University, Medical School, Istanbul, Turkey. Electronic address:

The link between the metabolic syndrome (MetS) and skin diseases is increasingly important, with new associations being discovered. The association between MetS and psoriasis or MetS and hidradenitis suppurativa is well known, although the relationship between MetS and various autoimmune or inflammatory diseases has only recently attracted interest. Some inflammatory skin diseases, such as vitiligo, scleredema, recurrent aphthous stomatitis, Behçet disease, rosacea, necrobiosis lipoidica, granuloma annulare, skin tags, knuckle pads, and eruptive xanthomas, have possible associations with MetS.

Application of vibration to wrist and hand skin affects fingertip tactile sensation.

Physiol Rep 2015 Jul 14;3(7). Epub 2015 Jul 14.

Division of Occupational Therapy, Department of Health Professions, Department of Health Sciences and Research, Medical University of South Carolina, Charleston, South Carolina, USA

A recent study showed that fingertip pads' tactile sensation can improve by applying imperceptible white-noise vibration to the skin at the wrist or dorsum of the hand in stroke patients. This study further examined this behavior by investigating the effect of both imperceptible and perceptible white-noise vibration applied to different locations within the distal upper extremity on the fingertip pads' tactile sensation in healthy adults. In 12 healthy adults, white-noise vibration was applied to one of four locations (dorsum hand by the second knuckle, thenar and hypothenar areas, and volar wrist) at one of four intensities (zero, 60%, 80%, and 120% of the sensory threshold for each vibration location), while the fingertip sensation, the smallest vibratory signal that could be perceived on the thumb and index fingertip pads, was assessed.

[Ainhum and "African acral keratoderma": three cases].

Ann Dermatol Venereol 2015 Mar 23;142(3):170-5. Epub 2015 Jan 23.

Service de dermatologie, hôpital Saint-Louis, AP-HP, 1, avenue Claude-Vellefaux, 75010 Paris, France. Electronic address:

Background: Ainhum, or spontaneous dactylitis, involves the formation of a gradual constriction in the digital-plantar fold of the fifth toe that leads, after several years, to autoamputation of the digit. This condition is classically distinguished from "true" ainhum, of unknown aetiology and affecting only subjects of African origin, from "pseudo-ainhum", resulting from different causes such as inflammatory constriction or constriction by a foreign body, and finally from ainhumoid palmoplantar keratoderma, which is of genetic origin and occurs for instance in Vohwinkel syndrome. Herein, we report three cases of ainhum in women of sub-Saharan African origin; in addition, all three subjects were also presenting various forms of hyperkeratosis of the hands and feet known to primarily affect subjects of African origin.

IDI-IRCCS Biochemistry laboratory c/o Dep. of Experimental Medicine, University of Tor Vergata, Via Montpellier, 1. 00133 Rome, Italy.

Epidermolytic PalmoPlantar keratoderma (EPPK) Vörner-type is an autosomal dominantly inherited skin disease, characterized by severe thickening of the palms and soles, caused by mutations in the keratin K9 (KRT9) gene. To date, a number of KRT9 mutations have been detected, most of which affect the highly conserved 1A region of the central alpha-helical domain, important for keratin heterodimerization. The most common mutation is the substitution of the arginine in position 163 with a tryptophan (R163W), which has been reported in North American, European, and Japanese populations. Read More

Zentrum für Humangenetik, Philipps-Universität Marburg, Bahnhofstr. 7, Marburg, Germany.

Camptodactyly (MIM 114200) is a digit deformity characterised by permanent flexion contracture of fifth fingers at the proximal interphalangeal (PIP) joints. The sporadic cases are common but a familial occurrence is not much appreciated. In an attempt to identify the genetic basis of camptodactyly, we have analysed a large German family with camptodactyly segregating in an autosomal dominant fashion. Read More

Lubrication regime of the contact between fat and bone in bovine tissue.

Proc Inst Mech Eng H 2007 May;221(4):351-6

Institute of Medical Engineering and Medical Physics, Cardiff University, Cardiff, UK.

Fat pads are masses of encapsulated adipose tissue located throughout the human body. Whilst a number of studies describe these soft tissues anatomically little is known about their biomechanics, and surgeons may excise them arthroscopically if they hinder visual inspection of the joint or bursa. By measuring the coefficient of friction between, and performing Sommerfeld analysis of, the surfaces approximating the in vivo conjuncture, this contact has been shown to have a coefficient of friction of the order of 0.

Video game induced knuckle pad.

Pediatr Dermatol 2006 Sep-Oct;23(5):455-7

Division of Dermatology, Department of Medicine, Medical College of Georgia, Augusta 30904, USA.

Controversy and concern surround the video game playing fascination of children. Scientific reports have explored the negative effects of video games on youth, with a growing number recognizing the actual physical implications of this activity. We offer another reason to discourage children's focus on video games: knuckle pads. Read More

Towards characterization of palmoplantar keratoderma caused by gain-of-function mutation in loricrin: analysis of a family and review of the literature.

Br J Dermatol 2006 Jan;154(1):167-71

Division of Dermatogenetics, Cologne Centre for Genomics, University of Cologne, Zülpicher Str. 47, 50674 Cologne, Germany.

Loricrin keratoderma is an autosomal dominant palmoplantar keratoderma heterogeneous in clinical appearance. We report a family with diffuse ichthyosis and honeycomb palmoplantar keratoderma but no occurrence of pseudoainhums or autoamputations. All patients were born as collodion babies and displayed prominent knuckle pads. Read More

Palmar-plantar fibromatosis in children and preadolescents: a clinicopathologic study of 56 cases with newly recognized demographics and extended follow-up information.

Am J Surg Pathol 2005 Aug;29(8):1095-105

Department of Soft Tissue Pathology, Armed Forces Institute of Pathology, Washington, DC 20306, USA.

Palmar-plantar fibromatosis, the most common type of fibromatosis, is well recognized in the adult population, but many clinicians and pathologists are unfamiliar with the fact that children may also be affected by this process. This report describes the clinicopathologic findings in 56 cases of palmar-plantar fibromatosis in children and preadolescents. Our study group included 19 males and 37 females, ranging from 2 to 12 years of age at the time of their first surgical procedure (median age, 9 years). Read More
