Phacomatosis pigmentokeratotica is characterized by the coexistence of an organoid epidermal naevus, follow-ing Blaschko's lines, and a large speckled lentiginous naevus, typically arranged in a chequerboard pattern. This entity has been isolated from the group of epidermal naevus syndromes and is frequently associated with extracutaneous anomalies. We report here the first observation of phaco...

To the Editor: Nevus sebaceous (NS) is an epidermal nevus that is comprised predominantly of sebaceous glands in approximately 0.3% of newborns.[1] Clinically, it presents as a single or, less commonly, multiple yellowish‐colored plaques with overlying alopecia, usually confined on the scalp; however, it can also appear on the face, preauricular area, and neck region.[2,3] Here, we reported a c...

We report a case of basal cell carcinoma that appeared from an epidermal verrucous nevus in a 61-year-old patient. The onset of basal cell carcinoma in sebaceous nevi, basal cell nevi and dysplastic nevi is relatively common, but it is rarely associated with epidermal verrucous nevi. There is no consensus on whether the two lesions have a common cellular origin or whether they merely represent ...

Introduction: A clinical “halo nevus” is a benign melanocytic-neoplasm, often exhibiting spontaneous involution. A characteristic clinical feature is depigmentation of the surrounding skin, and a centripetal progression of the tumor regression phenomenon. Case Report: An 18 year old male consulted the dermatologist for changes in color of an asymptomatic mole. Materials and Methods: A clinical ...

Patients with keratotic lesions distributed in a unilateral, linear, zosteriform or localized pattern and revealing histopathologic features of dyskeratotic acantholysis have been reported previously. There is some controversy in the appropriate nosologic classification of this entity. Some authors consider it as a localized form of Darier’s disease while others place it as a variant of e...
