Clinical, dermoscopic and histological features of a combined tumor composed of a melanoma in situ, a basal cell carcinoma and an intradermal naevus

چکیده
The combined tumors are neoplasms consisting of 2 or more distinct cell population that are intimately admixed. The presence of more than one neoplasm in the same lesion comprising melanocytes and keratinocytes are rare but well documented. We report a case of a 65-year-old man with a melanoma in situ, a basal cell carcinoma and an intradermal naevus in collision that clinically appeared as a single lesion. Clinical, dermoscopic and histological features are discussed.

Background and aim: Basal cell carcinoma (BCC) is the most common skin cancer in white-skin populations. Recent studies suggest that BCC is not a single entity and different histological subtypes show different clinical behavior and might have different etiology.

Basal cell carcinoma (BCC) is currently the most common cutaneous cancer found in humans. Although it generally shows a relatively benign course (BCCl), some cases show aggressive behavior (BCC2). Until recently, traditional histologic diagnostic criteria have failed to discriminate unequivocally between BCC 1 and BCC2. In this study we selected 50 cases of BCC and categorized them into tw...
