The surgical approach to lentigo maligna is a challenge to dermatologists, given the difficulty of clinical delimitation of borders. We report here a case of a 69-year-old female patient presenting with brownish macules on her face, since 10 years ago, with histopathological diagnosis of lentigo maligna. The surgical management employed was excision of visible borders with the contoured techniq...

Thirty-eight cases of lentigo maligna and 22 cases of lentigo maligna melanoma, were reviewed in order to compare cure rates of various methods of treatment. Surgical excision resulted in the best cure rate (91%); destructive modalities were less successful (45%). All lesions treated with 5% 5-fluorouracil recurred.

IMPORTANCE The diagnosis of extrafacial lentigo maligna can be a challenge because the dermoscopic features are not well described. These features can share some of the criteria of superficial spreading melanoma and some of facial lentigo maligna; however, these features are often absent. A new dermoscopic pattern has recently been described as forming angulated lines. OBSERVATIONS We report ...

This paper investigates solutions to improvement of realistic rendering quality of CG (Computer Graphics) character face. In order to manipulate face skin feature distribution, based on bio-anatomic structure, skin surface is classified into 3 layers(Internal, Regular and Local layer) to control skin base color, surface cellular venation level and noise distribution like freckle, respectively. ...

Neurofibromatosis (NF) is an inherited disorder characterized by the development of a wide variety of clinical manifestations, including characteristic "freckle-like" pigmentations (cafe au lait spots) that develop in infancy, followed by skin tumors that may vary widely in size, number, and distribution. In addition to skin tumors, bone, neurologic, and endocrine abnormalities are common. NF i...

Background and aim: It seems that melanocytic nevi, freckle and lentigo are more common in women with melasma, and a common genetic background may exist. In this study the prevalence and number of lentigo, freckle and melanocytic nevus were compared in women with and without melasma.Materials and methods: In a case-control study, 120 women with melasma (case group) and ...
