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)
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)
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 derma-toscope), is usually viewed as either unnecessary or expensive by young dermatologists. In reality, there is no need to buy(More)

BACKGROUND Because body weight-bearing produces a shift in the horny layer, acral melanocytic nevus on the body weight-bearing area of the sole showed a regular fibrillar pattern (FP) due to slanting of the melanin columns in the horny layer. On the other hand, acral lentiginous melanoma (ALM) on the body weight-bearing area of the sole tended to show(More)
Granuloma annulare has been associated with systemic disease including diabetes mellitus. We report a case of a 62-year-old Japanese woman with generalized erythematous granuloma annulare who showed remission after substantial improvement in hyperlipidemia following a strict lipid-lowering diet. The lesion appeared in the lower abdomen one year before(More)
