Verrucous hemangioma (VH) is an uncommon, congenital, vascular anomaly that resembles angiokeratoma but it encompasses distinctive clinicopathological features. The differential diagnosis of this entity included all the hyperkeratotic vascular tumors and malformations and, especially in localized cases, pigmented lesions. VH lesions initially present at birth, and therefore, the diagnosis in th...

Epidermal changes including hyperkeratosis and epidermal verrucous changes, papillomatosis, secondary infection, recurrent erysipelas and ulceration are complications of chronic lymphedema. Elephantiasis is a term used for these significant changes. Xanthoma may also develop in lymphedematous areas. Lymphangiosarcoma is a rare complication of chronic lymphedema. Nodular fibrosis is mentioned as...

Observations: Porokeratosis is a dyskeratotic disorder of the skin characterized by hyperkeratotic papule or plaque with an annular appearance and usually diagnosed easily, both histopathologically and clinically. We present a case of linear porokeratosis which was most likely suggesting the linear epidermal nevus and linear lichen planus. We observed a tiny brown border in the dermoscopic exam...

a variety of verrucous and papillary lesions affect the oral mucosa. Those which are benign and reactive, for example squamous papilloma or verruciform xanthoma, usually present little diagnostic difficulty. However, dysplastic and malignant verrucous and papillary lesions are a much greater diagnostic challenge, not helped by confusing terminology. papillary hyperplasia is a reactive inflammat...

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...
