[Current diagnostics and therapy recommendations for ocular basal cell carcinoma].

The treatment options for basal cell carcinoma (BCC) have recently been augmented with the introduction of novel chemotherapeutic drugs. New S2 guidelines on the disease have also been published. The aim of this article is to present a comprehensive state of the art description of the features of ocular BCC and an overview of the various therapeutic options. Particular emphasis is placed on the clinical signs, the diagnostic tools to identify periocular BCC and interpretation of the different histopathological subtypes. Tumor staging, TNM classification, interdisciplinary tumor conference reviews as well as psycho-oncological services play an important role in patients with pronounced periocular BCC. 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. A special focus of this article is the treatment of locally extensive and metastasized BCC.
