Carcinoma a cellule basali cistico: Considerazioni cliniche ed istologiche

Basal cell carcinoma is the most frequent malignant skin tumour and is generally closely connected with the epidermis. It can take various forms and may in some cases present cysts, generally microcysts. It is very rare for a basal cell carcinoma to manifest an extensive unilocular cyst unconnected with the epidermis. One such case will be described in this paper and concerns a 45-year-old man, for 5 years presenting a tumour of the cheek, clinically diagnosed as a sebaceous cyst. Only histological examination was able to show that it was instead a basal cell carcinoma. The case in question points to the appropriateness of careful histological testing in all cystic skin lesions, even the apparently most insignificant ones.
