[Differential, oncologically adequate therapy of basalioma]. / Differenzierte, onkologisch adäquate Therapie des Basalioms.

Surgical treatment of basal cell carcinoma demands straightforward tumor management. This study investigated the radicality of surgical excision, procedures performed for defect coverage, the recurrency rate depending on the histological tumor type, among other parameters. Despite a low general incidence of 14%, sclerodermiformal BCC (morphea-like lesions) is found in 88% of all recurrencies. Based upon the results of this study, the following therapeutic guidelines are recommended: Resection with tumor-free margins must be insisted on, particularly in any exposed surfaces of the body. Histological subtyping by the pathologist is required. After initially incomplete resection in certain histological subtypes, subsequent radical resection is not mandatory. Complete resection of sclerodermiformal BCC is mandatory, and continuous follow-up of these cases is recommended.
