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 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 کاملCombined Papillated Bowen Disease and Clear Cell Atypical Fibroxanthoma
We describe a case of papillated Bowen disease (PBD), associated with a clear cell atypical fibroxanthoma (CCAFXA). The epidermal lesion showed a bowenoid papillomatous growth pattern with histologic features suggestive of infection by human papilloma virus (HPV). In the dermis a neoplasm made up by spindled or polygonal cells with wide clear cytoplasm and moderate nuclear pleomorphism was foun...

could be discerned. Biopsy showed a tumor confined to the epidermis with acanthosis, a certain degree of papillomatosis, markedly atypical cells, and mitotic figures, with a completely intact basement membrane. Immunohistochemical studies using markers such as Melan-A and pancytokeratin cocktail confirmed the nature of the tumor, which was diagnosed as a case of pigmented Bowen disease. We exci...
متن کاملExtreme Bowen-York initial data
The Bowen-York family of spinning black hole initial data depends essentially on one, positive, free parameter. The extreme limit corresponds to making this parameter equal to zero. This choice represents a singular limit for the constraint equations. We prove that in this limit a new solution of the constraint equations is obtained. These initial data have similar properties to the extreme Ker...
