ABSTRACT
Background: Basal cell carcinoma (BCC) is a neoplasm that originates in the basal cells of the epidermis and hair follicles, is part of the group of non-melanoma skin cancers (NMSC) and is considered the most common. Locally is not so aggressive, but if allowed to progress becomes very destructive. Dermoscopy as a complementary non-invasive study has facilitated the diagnosis of those cases that do not shows clinical signs characteristics or suggestive of BCC, this tool is used by experienced dermatologists, offers a diagnostic sensitivity and specificity of 96 and 89% respectively. In addition to this, it has been shown that there is a correlation between dermatoscopic signs and histological structures of this neoplasm.
Objetive: Demonstrate the correlation between different clinical varieties of BCC, with dermatoscopic and histologic findings.
Methods: This was a descriptive study, with non-random sampling of consecutive cases of BCC, diagnosed between March and June, 2012, in the Department of Dermatooncology of the Dermatology Center «Dr. Ladislao de la Pascua». Dermoscopy images of histopathologically confirmed cases were evaluated by three experienced and certified dermatooncologyst. In all cases and individually, they classified the presence or absence of each of the dermatoscopics signs.
Results: We included 62 patients with confirmed diagnosis of BCC with histology. The clinic range observed was nodular with 76%, followed with 11% flat scar. The predominant histological type solid BCC corresponded to 32% of cases, followed by 23% infiltrating variety. Dermoscopic signs most frequently found were: telangiectasias (66%), gray blue blood (65%) and white shiny pink area (62%). Regarding clinical-dermoscopic correlation is observed: variety nodular gray blue blood predominated (73%), in the plane scar bright pinkish white area (76%), in the superficial gray blue nests (100%) in morphoeic telangiectasia (100%). In histological-dermoscopic correlation, the following findings were obtained: in the BCC solid telangiectasias were observed (97%) and gray blue blood (66%) were infiltrating in telangiectasias (72%), ulceration, white bright pink area blue and gray pigment cells (61%) and multifocal surface areas were observed bright pink and white maple leaves (100%) respectively. Conclusions: This study confirms that there is a correlation between signs dermatoscopic with clinical and histological varieties of BCC.
