RESUMO
Abstract: A 70-year-old woman was referred to our dermatological unit by her general practitioner last summer, with a history of a two-month ulcerated purplish lesion on her left arm that spread centrifugally and that unsuccessfully treated with topical corticosteroids. The dermoscopic evaluation revealed an erythematous macula with central ulceration that showed the characteristic called "white starburst-like pattern" and some vascular structures (dotted vessels, polymorphous⁄ atypical vessels). The diagnosis of cutaneous leishmaniasis was made after histopathologic analysis and polymerase chain reaction essay.

SUMMARY Basosquamous carcinoma (BSC), as described in 1910, is a distinctive variety of skin cancer and its etiology and pathological characteristics have generated much controversy over the years. Currently, BSC is considered a basal cell carcinoma (BCC) subtype with aggressive behavior and greater tendency for recurrence and metastases. We present a clinical case recently reported in our unit.
