Although frequently performed, laser removal of pigmented lesions still contains certain controversial issues. Epidermal pigmented lesions include solar lentigines, ephelides, café au lait macules and seborrheic keratoses. Dermal lesions include melanocytic nevi, blue nevi, drug induced hyperpigmentation and nevus of Ota and Ito. Some lesions exhibit both an epidermal and dermal component like ...

Blue nevus is an uncommon pigmented lesion of dermal melanocytes. By convention, two well defined histologic variants, designated as "common" and "cellular", have been recognized. These lesions have attracted much attention due to its confusion with malignant melanoma. We present a case of a giant congenital cellular blue nevus of neck clinically presenting as malignant melanoma and infiltratin...

Hamartoma or nevus oligemicus is an uncommon lesion that is characterized by selective vasoconstriction of the deep dermal vascular plexus with respect to the superficial one and whose cause has not been clearly established. This selective vasoconstriction gives rise to fixed, acquired, and asymptomatic lesions in the form of livid, erythematous macules that are typically cold to touch compared...

We treated a 65-year-old woman with familial cylindromatosis, with cylindromas covering the entire scalp. Subgaleal tumor excision and split skin grafting was performed. The graft take was deemed to be excellent, with almost 100% coverage 2.5 weeks after operation, no complications and a satisfying esthetic result.

Dermal melanocytosis refers to congenital or acquired lesions characterized by the presence of dendritic cells derived from melanocytes that migrate from the neural crest to the epidermis. The nevus of Ito develops in the territory supplied by the acromioclavicular nerve. Malignant transformation in dermal melanocytosis is extremely rare, with only isolated case reports; only 2 cases of maligna...

Patients with the autosomal-dominant form of multiple familial trichoepithelioma develop numerous tumours on the face, neck and upper trunk, beginning in childhood. Malignant transformation of such lesions is quite rare; only one case of "malignant trichoepithelioma" has been reported previously, inferring pilomatrix carcinoma on a histological observation. We report here the case of a patient ...

Eccrine spiradenoma (ES) very rarely presents in a linear or zosteriform distribution. It may be associated with foci of various other appendageal tumors. We report a 14-year-old boy who presented to us with multiple nodules in a linear distribution in the posterior aspect of the right lower limb since 2 years of age. The lesions became significantly painful for the past 2 years. Histopathology...

AIMS To prospectively evaluate the reliability and efficacy of a new treatment for the reconstruction of the lacrimal duct using a new histo-engineered material, xenogeneic (bovine) acellular dermal matrix. METHOD Five patients (five eyes) with partial or total absence of the lacrimal duct were included in the study. Four patients (four eyes) suffered from traumatic injuries to the lacrimal d...
