The cutaneous horn is a clinical finding rooted in a variety of different benign and malignant causes. Sampling with subsequent histologic examination is the diagnostic gold standard. Depending on the causing pathology, different therapies are necessary. We report a case in which a patient presented to our outpatient clinic with two cutaneous horns of the lower lip. A biopsy had already been performed in another clinic five years ago, in which a not fully excised, well-differentiated squamous cell carcinoma (G1), was found. The patient refused further surgical treatment recommendations at the time. Due to the size-progressive and functionally limiting findings, the patient presented to our clinic. After removal of the lesions, a histological examination was performed. Apart from verrucous hyperplastic squamous epithelium, no evidence of malignancy was histologically found.
As there were no histologically visible signs of malignancy, the patient was discharged in an aesthetically and functionally acceptable state into a follow-up program with clinical check-ups every six months in order to detect and remove any recurrences at an early stage.
