Non-invasive techniques in the clinical diagnosis of cutaneous lymphomas.

In clinical practice, cutaneous lymphomas can be challenging to diagnose or even suspect because they mimic a variety of other inflammatory and neoplastic dermatological conditions. Support for non-invasive skin analysis methods like reflectance confocal microscopy and dermoscopy is still anecdotic. Practically speaking, a deeper and more comprehensive study with a larger number of cases focusing on the effective usefulness of non-invasive techniques should be taken into consideration because they have demonstrated the ability to identify macro and micro features supporting the clinical suspicion of lymphomas, as well as being useful for differential diagnosis and supporting the selection of the biopsy site. The author provides a brief and narrative synopsis of the reflectance confocal microscopy and dermoscopy characteristics of cutaneous lymphomas in this manuscript.
