Individuals with skin of color (SOC) are defined by the Skin of Color Society as those individuals of Hispanic/Latino, Asian, African, Native American, Pacific Island descent, and mixtures thereof. All too often skin cancers are detected late in persons of skin of color due to many factors including health inequity, poverty, lack of access to education and healthcare. +
Dermoscopy has been used for many years in the differential diagnosis of pigmented skin tumors and has been proven superior to naked-eye examination in the differential diagnosis of melanoma on the skin. +
This article reviews the dermoscopy of basal cell carcinoma and its subtypes such as superficial BCC, morpheiform BCC, nodular BCC and fibroepithelioma of Pinkus. +
The top-down 2-step pattern analysis approach builds upon the previous classic and revised 2-step approaches by eliminating the requirement to differentiate melanocytic from non-melanocytic lesions in step +
Dermoscopy can help identify different subtypes of skin cancers, which can have important therapeutic implications. For example, dermoscopic structures more frequently associated with non-superficial, mostly nodular BCC, are blue-ovoid nests, arborizing vessels, and ulceration, and warrant surgical excision. +
Basal cell carcinoma (BCC) is the most common type of skin cancer in the world. Although mortality related to BCC is negligible, BCCs can be associated with significant morbidity, especially if left untreated and/or if discovered when they have attained relatively large diameters. Clinically, BCC can present with a variety of morphologies ranging from erythematous patches to ulcerated nodules. There are multiple histopathologic subtypes of BCC including superficial, nodular, morpheaform/sclerosing/infiltrative, fibroepithelioma of Pinkus, microcytic adnexal and baso-squamous cell BCC. Each subtype can be pigmented or non-pigmented [1]. +

The most frequent structures seen in inflammatory skin diseases are vessels, scales or crusts and criteria associated to the hair follicle. In this chapter we describe the most important parameters to be evaluated when dermoscopically examining skin eruptions. +
Dermoscopy evaluates the lesion in all its extensions on a horizontal plane. This can allow the selection of the best area to biopsy in large lesions, as well as giving information to the pathologist of the most representative area to section. Improvement in sampling can occur either using dermoscopy in the clinical setting or by using dermoscopy directly in the excised specimen in the laboratory (ex vivo dermoscopy). Ex vivo dermoscopy (EVD) is a valuable tool since most dermoscopic features are visible even after formalin fixation. +
Dermatofibromas (DFs) are prevalent cutaneous lesions that most frequently affect young to middle-aged adults, with a slight predominance in females. Clinically, dermatofibromas appear as firm, single or multiple papules/nodules with a relatively smooth surface and predilection for the lower extremities. Characteristically, upon lateral compression of the skin surrounding dermatofibromas, the tumors tend to pucker inward producing a dimple-like depression in the overlying skin; a feature known as the dimple or Fitzpatrick’s sign. +
Squamous cell carcinoma (SCC) is the second most common cutaneous malignancy after Basal Cell Carcinoma with an increasing incidence worldwide. It usually arises on sun-exposed areas of the skin, such as scalp, face, neck, forearms and dorsal hands[1]. +
