Multicentric Bowen disease in linear porokeratosis.
Linear porokeratosis is a genodermatosis, caused by a clonal proliferation of keratinocytes along the lines of Blaschko. This type of porokeratosis is particularly susceptible to malignant degeneration e.g. to Bowen disease, a squamous cell carcinoma (SCC) in situ with the potential for significant lateral spread. Here we report a case of linear porokeratosis on the left leg of a 56-year-old ma...
متن کاملPorokeratosis simulating Bowen’s disease on dermoscopy*
Porokeratosis is a disorder of epidermal keratinization characterized by the presence of annular hyperkeratotic plaques. Its etiopathogenesis is not yet fully understood, but a relationship with immunosuppression has been reported. Dermoscopic examination revealed a classic yellowish-white ring-like structure that resembled "volcanic crater contour" - the so-called cornoid lamella. We describe ...
متن کاملPagetoid Bowen Disease Initially Misdiagnosed as Ectopic Extramammary Paget's Disease
Pagetoid Bowen disease is a histological variant of Bowen disease which demonstrates large pale staining cells (pagetoid cells). It requires differential diagnosis from other cutaneous malignancies with similar patterns, such as extramammary Paget's disease (EMPD) and Pagetoid melanoma in situ. Herein, we report a case of Pagetoid Bowen disease which was initially misdiagnosed as ectopic EMPD.
متن کاملCoexistence of Disseminated Superficial Actinic Porokeratosis and Ptychotropica Porokeratosis
Porokeratosis (PK) is an uncommon disorder of epidermal keratinization characterized by annular plaques with an atrophic center surrounded by a raised, keratotic wall, with unknown aetiology and an unpredictable outcome. It has several clinical forms including porokeratosis of Mibelli, giant porokeratosis, linear porokeratosis, disseminated superficial actinic porokeratosis, palmoplantar ...
متن کاملLinear porokeratosis.
Linear porokeratosis is a rare variant. It can be present at birth or can develop in adult life. Lesions of linear porokeratosis are grouped and linearly arranged along the lines of Blaschko. On the extremities it affects the distal portion more than the proximal areas. On the trunk these can be zosteriform in distribution. Lesions of linear porokeratosis probably result from an abnormal clone ...
