Unlabelled: Non-melanoma skin cancer (NMSC) is the most common malignancy in fair skinned populations. Dermoscopy, reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) are non-invasive imaging techniques that play an important role in diagnosis of skin tumors. The aim of this study was to provide new insights into the role of non-invasive tecniques in the diagnosis of non-melanoma skin cancers, concentrating especially on dermoscopy, RCM and OCT. The analysis of the studies obtained from the most recent literature, taking into account previous essential reported information in this field. A search concerning the role of dermoscopy, RCM and OCT in the diagnosis of NMSC was performed on PubMed.
Exclusion Criteria: duplicated studies, single case report, and papers with language other than English New and old literature about early diagnosis of NMSC through non-invasive imaging techniques were analyzed. The role and the diagnostic accuracy of dermoscopy, RCM and OCT for the diagnosis of NMSC were reported according to the data given by literature. The development of non-invasive diagnostic devices (especially dermoscopy, RCM and OCT) allows tissue imaging in-vivo contributing to a more accurate diagnosis of skin cancer, sparing time for the patient and costs for the public health system.

Early detection and comprehensive diagnostic approaches for breast cancer are essential for improving prognosis. When it comes to changes in the skin of the breast or the nipple-areola complex (NAC), particularly if they are unilateral, it is essential to be vigilant, as these changes could be an early sign of underlying malignancy or other pathologies. Primary breast malignancies, such as mammary Paget's disease (MPD), can manifest as erythema, scaling, or ulceration of the NAC, while secondary cutaneous metastases from other breast carcinomas may present as nodules, erythematous plaques, or inflammatory reactions.

Background/objectives: Hidrocystomas, eccrine and apocrine, are rare cystic lesions that form benign tumors of the sweat glands. This study aimed to describe the clinical features of hidrocystomas and evaluate the role of non-invasive imaging techniques, including dermoscopy, Line-field Confocal Optical Coherence Tomography (LC-OCT), Reflectance Confocal Microscopy (RCM), and Ultra-High-Frequency Ultrasound (UHFUS), in their diagnosis.
Methods: In total, seven cases of hidrocystomas were collected from the Dermatologic Clinic of the University of Siena, Italy.

Article Synopsis
- Facial pigmented skin lesions are common, especially in South-European countries, and can be either malignant or benign; diagnosing them can be challenging, even for specialists like dermatologists.* -
- A study was conducted to assess the impact of a one-day dermoscopy training course on ophthalmologists, focusing on their ability to evaluate periorbital pigmented lesions through clinical and dermoscopic analysis.* -
- Results showed that before the training, ophthalmologists had an accuracy of 63.7%, but after the course, their sensitivity improved, indicating a positive effect of the training on their diagnostic skills.*
Lentigo maligna (LM) often poses a diagnostic challenge due to its clinical and dermoscopic mimicry of benign lesions, leading to delayed diagnosis. Focal areas of reticular disruption have been described as one of the earliest dermoscopic signs observed. To describe a novel dermoscopic sign in LM, namely the presence of a parallel pigmented network.

Primary cutaneous lymphomas (PCL) are a heterogeneous group of non-Hodgkin lymphomas arising from malignant T (CTCL) or B (CBCL) cells, often mimicking other skin conditions. Recently, non-invasive diagnostic imaging modalities, including dermoscopy, Reflectance Confocal Microscopy (RCM), and Line-field Optical Coherence Tomography (LC-OCT), have become increasingly important, supporting clinicians in clinical practice. Hence, our study aimed to describe dermoscopic, RCM, and LC-OCT features of PCL and to explore their role in PCL management.
