Abstract: Dermoscopic examination allows visualization of horizontal images on the skin, showing well-defined patterns. The authors propose ex vivo dermoscopic visualization using a vertical view of skin sections. The new image clearly distinguishes the stratum corneum, epidermis, and dermis as well as t...
This study aimed to establish the incidence of skin tumors (cutaneous proliferative lesions of neoplastic or non-neoplastic nature) in dogs diagnosed by histopathological evaluation at the Veterinary Pathology Laboratory (LPV) of the Federal University of Bahia (UFBA) in a 10-year (2007-2016) historical ...
Abstract: Bowen's disease is a type of squamous cell carcinoma in situ of the skin. The pigmented form is rare and represents less than 2% of cases.

Abstract: Background: Pigmented lesions on acral sites are common; clinical differentiation of nevi and early melanoma can be challenging. In these cases, dermoscopy can provide a more accurate diagnosis. Most dermoscopic patterns on acral skin have been described in Asian and European populations, whil...
Abstract: Background: Mycosis fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma. TNMB system is the staging method used in MF, and it not only guides therapeutic management, but represents the main prognostic factor. In order to improve the prognostic evaluation, the Cutaneous Lymph...

Tailgut cysts are generally multilocal and have a layer of either columnar, squamous or transitional epithelium, or a combination of these. This case was treated with surgi...
Abstract: Verrucous hemangioma is a rare vascular skin disorder with an immune profile similar to vascular neoplasms, but with behavior and evolution of vascular malformations. Its main differential diagnosis is angiokeratoma circumscriptum neviforme, with an almost indistinguishable clinical presentatio...
