Therapeutic difficulties in medial canthus carcinoma

The cutaneous neoplasms of the medial canthus are at the intersection of several anatomical regions and, at the same time, of several surgical specialties: ENT surgery, plastic surgery, ophthalmology. The ideal ablation of a malignant lesion of the medial canthus implies negative margins and minimal aesthetic and functional deficit. In this article, we review the literature data on therapeutic principles in medial canthus skin tumors, and we present a clinical case of medial canthus basal cell carcinoma with recurrence after two years from the first surgery. The surgery was performed in a mixed team, and the histopathology result was metatypical carcinoma with basal cell areas. The evolution of the case was favorable, without recurrence after five years of clinical and imaging monitoring. We discuss the therapeutic difficulties raised by a tumor case of medial canthus, insisting that the first surgery must be as radical as possible and with negative margins.
