This paper deals with image processing for automatic analysis of pigmented skin lesions. A special emphasis is put on pigmented networks in epiluminescence microscopy (ELM) images. The purpose of processing images with pigmented skin lesions is the visualisation for education and training as well as for diagnosis support. We use a colour based segmentation applied to the Karhunen-Lo eve transfo...

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 dots/globules, blue-whitish regression ...

Epidermal nevi are cutaneous hamartomas developing from ectoderm and one of their types is verrucous epidermal nevus. During the neonatal period, they are pink or slightly pigmented and velvety. Later, they darken and the surface become more warty. When lesions are distributed on one side of body, it is termed nevus unis lateralis. Lymphangioma is a lymphatic malformation which manifests with f...

Pigmented tumors have similar clinical features that overlap and hamper diagnosis. Dermoscopy increases the diagnostic accuracy of doubtful melanocytic lesions and has been used as a noninvasive tool in the detection of pigmented lesions (PLs) like melanoma, basal cell carcinoma, and pigmented Bowen's disease (pBD). Our objective was to show the dermoscopic features of 2 cases of pBD and compar...

Dentists may encounter pigmented lesions in routine clinical practice. In most cases, the lesions are asymptomatic and benign in nature; however, rarely, a pigmented lesion can be a sign of malignancy. We report a case of malignant melanoma of the maxillary gingiva to highlight the importance of biopsy and periodic follow-up of patients with unusual focal pigmented lesions in the oral cavity.

Pigmented lesions are commonly found in the mouth. Such lesions represent a variety of clinical entities, ranging from physiologic changes to manifestations of systemic illnesses and malignant neoplasms. Evaluation of a patient presenting with a pigmented lesion should include a full medical and dental history, extraoral and intraoral examinations and, in some cases, biopsy and laboratory inves...
