[SOP - Standarized procedures in diagnostics and therapies of periocular basal cell carcinoma].

The basal cell carcinoma (BCC) is the malignant eye tumor with the highest incidence. The aim of this article is to present a systematic and standardized approach to diagnose, treat and care periocular basal cell carcinoma. Interpretation of clinical signs, diagnostic tools to identify periocular BCC and interpretation lead to the appropriate choice of therapy. Surgical removal with a histological R0 resection is an important component of therapy options in this disease and includes the microsurgical excision into healthy tissue and the subsequent covering of the defect. Alternative treatment options are targeted therapies with hedgehog inhibitors and beam radiation in excessive basal cell carcinoma. Also, aftercare of patients with basal cell carcinoma follows the treatment. A special focus of this article is the treatment of locally extensive and metastasized BCC and the national S2 guidelines of this tumor.
