Lichen nitidus is an uncommon skin condition that is clinically characterized by the presence of pinpoint papules, which are usually asymptomatic, flesh colored, with a flat, shiny surface. The histopathologic feature of it is characteristic. We report a 30-year-old man with typical skin lesions of lichen nitidus confirmed with histopathology, who also had multiple palmar pits. Treatment ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016216050 DESCRIPTION A 68-year-old African-American man with a history of duodenal adenocarcinoma was found to have innumerable 1 mm hyperkeratotic depressions along his palmar creases bilaterally (figures 1–3). The patient reported having these lesions since early in childhood. ...

Gorlin's syndrome, or basal cell nevus syndrome, is a relatively rare disease. It consists of a classic pentad of features comprised of multiple basal cell carcinomas, jaw cysts, calcification of the falx cerebri, pitting of the palmar and plantar surfaces and rib anomalies. A review of the clinical features, differential diagnosis, clinical work-up and current treatment is presented.

Cowden syndrome is a rare autosomal dominant disorder characterized by multiple hamartomas of the ectoderm and brain. A 36-year-old Japanese man presented with right facial seizure during sleep and was admitted to our hospital. He showed cobblestoning over the tongue and palmar pitting but no neurological abnormalities while he was not having a seizure. Brain magnetic resonance imaging showed f...

Reticulate acropigmentation of Kitamura (RAK) and Dowling-Degos Disease (DDD) are rare genodermatosis inherited as an autosomal dominant trait with variable penetrance. They are part of a spectrum of diseases with hyperpigmented macules coalescing in a reticular pattern, facial and palmoplantar pits, breaks in dermatoglyphics, comedo-like lesions and epidermoid cysts, and a unique histological ...

Paraneoplastic arthritides (PA) are a group of inflammatory arthropathies associated with latent or manifest malignancy, localized in distant site relation to the primary focus and caused by immune-mediated mechanisms. Although pathogenesis PA is unknown, mechanisms can cause paraneoplastic syndrome dominant feature polyarthritis. Arthritis be both initial manifestation disease, it itself some ...

Hydrostatic pressure effects on pitting initiation and propagation in X70 steel are investigated by evaluating metastable pitting probability using electrochemical methods and immersion corrosion tests in containing chlorine ion solution. Potentiodynamic tests indicated that hydrostatic pressure can decrease the breakdown potential and lead to a reduced transpassivity region. Metastable test re...

In this study, the pitting behaviour of a new corrosion-resistant alloy steel (CR) is compared to that of low-carbon steel (LC) in a simulated concrete pore solution with a chloride concentration of 5 mol/L. The electrochemical behaviour of the bars was characterised using linear polarisation resistance (LPR) and electrochemical impedance spectroscopy (EIS). The pitting profiles were detected b...

Pitting corrosion is localized accelerated dissolution of metal that occurs as a result of a breakdown of the otherwise protective passive film on the metal surface. This paper provides an overview of the critical factors influencing the pitting corrosion of metals. The phenomenology of pitting corrosion is discussed, including the effects of alloy composition, environment, potential, and tempe...

background: sdft, ddft and suspensory ligament are the most important tendons and ligament of the palmar aspect of the metacarpus that contribute to stability mechanism. objectives: the purpose of this study was to describe the tendons and ligaments of the palmar surface of metacarpus in anatoly donkey and compare them with those in horse. methods: 14 healthy anatoly donkeys without lameness we...
