Eccrine angiomatous hamartomas are benign vascular and eccrine malformations often accompanied by hyperhidrosis or pain, increased eccrine glands, and aggregates of vessels. Verrucous hemangiomas are congenital vascular malformations presenting as unilateral grouped papules. Histologically, they show verrucous epidermal change and proliferation of capillaries in the dermis. We report a case of ...

We report phakomatosis pigmentovascularis (PPV) detected in a 40yearold male characterized by the presence of a port-wine stain in the background of aberrant Mongolian spots covering the back, nevus of Ota, ocular melanosis, epidermal nevus and a scaly patch with the diagnosis of discoid lupus erytematosus. These associations have not been reported yet.

Becker's nevus is a cutaneous hamartoma that may be present at birth, but more commonly is noticed during puberty. It classically manifests unilaterally on the shoulder and upper trunk as a tan to brown patch or thin plaque. "It typically has an irregular margin, breaks up into islands at the periphery, and has an average size of 125 square centimeters. Numerous skin, soft-tissue, and bony anom...

The Proteus syndrome comprises an association of asymmetrical overgrowth of almost any part of the body, verrucous epidermal naevi, vascular malformations and lipoma-like subcutaneous hamartoma. Both sexes are affected with equal frequency and severity and it is not transmitted genetically. Here a 16-year-old man with asymmetric overgrowth of the extremities, macrodactyly, cerebriform hypertrop...

BACKGROUND The epidermal nevus syndromes include different diseases that have the common feature of mosaicism. One of these has been recently identified and named phacomatosis pigmentokeratotica, in analogy to phacomatosis pigmentovascularis. It is characterized by an organoid nevus with sebaceous differentiation, a speckled-lentiginous nevus, and other associated anomalies. It has been hypothe...

This study addresses the development of an animal model for human giant congenital nevomelanocytic nevi (GCNN). Skin grafts were made from 1) non-involved split-thickness skin from a 12-month-old GCNN patient, 2) nevus split-thickness skin from the same GCNN patient, 3) nevus full-thickness skin, and 4) cadaveric human split-thickness skin. For groups 1) and 2), human epidermal and dermal cells...

Epidermal nevus syndrome is a kind of neurocutaneous syndrome that is associated with epidermal nevus and a variety of congenital CNS disorders. Clinical presentations include seizures, paresis, mental retardation, and developmental delay. We report three cases with MR imaging and magnetoencephalography findings; one patient underwent ictal and interictal single photon emission CT. Both structu...

Epidermal Nevus Associated with Cerebral and Ocular MR Imaging Abnormalities This letter focuses on Schimmelpenning syndrome (SS), a neurocutaneous disorder related to epidermal nevus syndromes and characterized by craniofacial nevus, neurologic anomalies, and ocular pathology. We discuss clinical and MR imaging features of a 10-year-old boy, pointing out the etiopathologic substratum of this c...
