The clinical and dermoscopic diagnosis of facial lentigo maligna (LM) and pigmented actinic keratosis (PAK) remains challenging, particularly at the early disease stages. To identify dermoscopic criteria that might be useful to differentiate LM from PAK, and to elaborate and validate an automated diagnostic algorithm for facial LM/PAK. We performed a retrospective multicentre study to evaluate dermoscopic images of histologically-proven LM and PAK, and assess previously described dermoscopic criteria.

Data on somatic heterogeneity and germline-somatic interaction in multiple primary melanoma (MPM) patients are limited. We investigated the mutational status of BRAF, NRAS, and TERT promoter genes in 97 melanomas of 44 MPM patients and compared molecular and immunohistochemical findings. We further evaluated the association of somatic alterations with the germline MC1R genotype.

The purpose of monitoring patients diagnosed with melanoma is to allow early detection of recurrence and any subsequent primary tumors. Several dermatological and oncological societies developed their own set of guidelines for the surveillance and management of melanoma patients depending on the stage of the disease.

Background: Correctly diagnosing basal cell carcinoma (BCC) clinical type is crucial for the therapeutic management. A systematic description of the variability of all reported BCC dermoscopic features according to clinical type and anatomic location is lacking.
Objectives: To describe the dermoscopic variability of BCC according to clinical type and anatomic location and to test the hypothesis of a clinical/dermoscopic continuum across superficial BCCs (sBCCs) with increasing palpability.
Background: The dermoscopic features of acral acquired melanocytic naevi have been extensively reported in the adult population. Little knowledge is available on acral naevi in childhood and adolescence.
Objectives: Firstly, to characterize the frequency of dermoscopic features of acral naevi and their distribution according to age groups in children and adolescents; and secondly, to analyse the type and frequency of their dermoscopic changes over time.
