Pigmented spots in the skin and mucosa (lentigines) can be found in various diseases called familial lentiginosis syndromes; Peutz-Jeghers syndrome (PJS) is one of them. It is characterized by the association of mucocutaneous melanin pigmentation and hamartomatous gastrointestinal polyps. Patients with PJS are at increased risk of intussusception and cancer development (gastrointestinal and non...

In my opinion, Salicylic acid at concentrations of 15-20% remains the best option for superficial peel in pigmented skin (Fitzpatrick types V and VI) with acne and/or excessive sebum secretion. At a lower concentration (15% -20%), Salicylic acid peel is equally effective in pigmented skin with acne. It reduces the number of both inflammatory and non-inflammatory lesions. It has a comedolytic ef...

In this paper we propose a machine learning approach to classify melanocytic lesions in malignant and benign from dermatoscopic images. The image database is composed of 433 benign lesions and 80 malignant melanoma. After an image pre-processing stage that includes hair removal filtering, each image is automatically segmented using well known image segmentation algorithms. Then, each lesion is ...
