Streamlined Management of Basal Cell Carcinoma with Dermoscopy: A Retrospective Case-Control Study

Background/Objective: The standard approach for managing suspected basal cell carcinoma (BCC) involves performing a biopsy to confirm the diagnosis before treatment. This process often leads to multiple visits and increased healthcare costs. We aimed to evaluate the effectiveness of direct surgical excision of BCCs diagnosed clinically and dermoscopically, without the need for prior biopsy. Methods: We conducted a retrospective case-control study at a tertiary cancer center. Lesions suspected to be BCC, based on clinical and dermoscopic criteria, were divided into two groups: (1) a streamlined treatment group (cases), in which lesions were treated without a confirmatory biopsy (either excised with a 4 mm margin or managed with curettage and electrodesiccation); (2) and a biopsied group (controls). Clinical and histopathological data were analyzed and compared between groups to assess diagnostic accuracy, margin status, and treatment outcomes. Results: Of 389 BCCs, 167 (42.9%) were streamlined, while 222 (57.1%) underwent a biopsy before definitive treatment. The streamlined group demonstrated higher diagnostic accuracy, with 94.6% of excised lesions confirmed as BCC, compared with 73.4% in the biopsy group (p < 0.001). Among lesions excised with 4 mm margins, 97.9% achieved clear margins with the streamlined approach. Margin involvement was associated with high-risk BCC (p = 0.048), particularly with recurrent BCCs (p = 0.023). Conclusions: Streamlined management of BCC through direct excision without prior biopsy is an efficient and cost-effective strategy that reduces patient visits, costs, and waiting times, particularly for low-risk BCCs and older patients. Advances in dermoscopy and non-invasive tools support their accuracy, making it a feasible option in resource-limited settings.
