Basal cell carcinoma (BCC) is the most common human cancer. Giant basal cell carcinoma is a rare variant of BCC, It represents only 0.4 - 1% of all BCC and is defined as a lesion greater than 5 cm it its largest diameter, most often occurring on the trunk. Giant BCC arising on the scalp is extremely rare. It presents some common epidemiological factors that include large tumor size, multiplicity of tumors, development on high-risk areas, neglect and tumor chronicity. Giant BCC can develop aggressive behavior resulting in deep local invasion, recurrence, potential regional and distant metastasis. The incidence of metastasis in basal cell carcinomas is rare and is calculated to be approximately 0.1%, most notably giant BCC, which has greater metastatic potential due to its large size. A giant basal cell carcinoma on the scalp is in some cases treated with a combination of surgery and radiation therapy, resulting in local control, a satisfactory long-term cosmetic and functional result.span style="font-family:Arial"> We report the case with a neglected basal cell scalp carcinoma, treated with wide excision of the tumor with flap placement. The cosmetic result is acceptable and there is no sign of recurrence 6 mouth postoperatively.
