BACKGROUND Computer-aided diagnosis of dermoscopy images has shown great promise in developing a quantitative, objective way of classifying skin lesions. An important step in the classification process is lesion segmentation. Many studies have been successful in segmenting melanocytic skin lesions (MSLs), but few have focused on non-melanocytic skin lesions(More)
A clinical diagnosis of lentigo maligna at an early stage is often difficult even for experienced dermatologists. Differential diagnoses would include solar lentigo, early lesions of seborrheic keratosis, lichen planus-like keratosis, pigmented actinic keratosis and melanocytic nevus. Dermoscopy has been shown to have higher diagnostic accuracy, especially(More)
Various structures have been reported for dermoscopic features of pigmented Bowen's disease (BD), which could be a mimic of various pigmented skin lesions. A 79-year-old Japanese woman presented with a 3-year history of brown-black macule on her right upper arm without symptom. Dermoscopic examination demonstrated irregular flossy streaks, irregular brown(More)
Eccrine porocarcinoma is a rare cutaneous neoplasm that mainly affects elderly people and grows slowly over a long period of time but often experiences an accelerated growth phase. Eccrine porocarcinoma may arise de novo or evolve from a pre-existing benign eccrine poroma. We reported a 86-year-old Japanese woman presenting with two reddish-colored(More)
The desmogleins are a family of cadherins cell-cell adhesion molecules consisting of proteins DSG1, DSG2, DSG3, and DSG4. They play a role in the formation of desmosomes, which form the major types of intercellular adhesive junctions. DSGs are currently thought to be involved in autoimmune diseases, infectious diseases, and inherited diseases. Patients with(More)
Practical, Conceptual & Educational Notes | Dermatol Pract Concept 2013;3(4):8 35 Dermoscopy is helpful not only in the early differentiation of melanoma from nevus and other pigmented skin lesions, but also in the diagnosis of non-pigmented skin lesions. However, the dermoscopy device, or dermoscope (or dermatoscope), is usually viewed as either(More)
A 43-year-old Japanese man presented with reddish nodules on the ankle. The nodules had a yellowish crust and eroded surface. Dermoscopy revealed red to milky-red globules at the periphery and some glomerular vessels in the center and a whitish-pink network, which corresponded to capillary dilatation in the papillary dermis and prominent acanthosis,(More)
Methods: We applied for the first time the two in vivo confocal microscopes commonly used in dermatology (VivaScope ® 1500 and 3000, CALIBER, distributed in Europe by Mavig GmbH, Munich, Germany) to observe the cornea, the bulbar and tarsal conjunctiva, the eyelid margin, the lacrimal punctum and the palpebral skin of healthy volunteers.
