OBJECTIVE Compare the dermatoscopy vascular features of well differentiated with non-well differentiated squamous cell carcinoma (SCC). DESIGN A prospective study of 294 consecutive cases of histopathologically confirmed invasive SCC compared the dermatoscopic vascular features of well to combined moderate and poorly differentiated tumors. These features(More)
BACKGROUND Cutaneous horns usually develop on a keratinocytic base with the histopathology on a spectrum ranging from benign keratosis through to invasive squamous cell carcinoma (SCC). Some features of horns are easily identified using dermatoscopy. OBJECTIVE To investigate if specific clinical or dermatoscopy features of horns correlate with the(More)
BACKGROUND Basal cell carcinoma (BCC) can present with indolent or aggressive subtypes. These subtypes usually display vascular features, which are often readily identified using dermatoscopy. OBJECTIVE Dermatoscopy vascular features of aggressive BCC were compared to superficial, superficial and nodular, and nodular BCC for diagnostic discrimination. (More)
INTRODUCTION Keratoacanthoma (KA) and invasive squamous cell carcinoma (SCC) are keratinocytic tumors displaying vascular features, imaged using dermatoscopy. OBJECTIVE Compare the dermatoscopy vascular features of KA to SCC. METHODS This prospective study examined consecutive cases of 100 KA and 410 invasive SCC in a single private practice in Sydney,(More)

Background: Non pigmented eccrine poroma is a benign tumor that can have dermoscopic features mimicking malign neoplasias. The characteristic vascular pattern of this tumor hasn't been established. We found a scarcely reported vas-cular pattern, which can be useful to distinguish this tumor from malignant ones and propose a new nomenclature to these vessels(More)
