Pigmented Nodular Basal Cell Carcinomas in Differential Diagnosis with Nodular Melanomas : Confocal Microscopy as a Reliable Tool for In Vivo Histologic Diagnosis

Abstract EN

Nodular basal cell carcinoma, especially when pigmented, can be in differential diagnosis with nodular melanomas, clinically and dermoscopically.

Reflectance confocal microscopy is a relatively new imaging technique that permits to evaluate in vivo skin tumors with a nearly histological resolution.

Here, we present four cases of challenging nodular lesions where confocal microscopy was able to clarify the diagnosis.
