Reflectance Confocal Microscopy Can Help in Detecting Clinically Silent Mammary Paget's Disease.

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.

Dermoscopy, Line-Field Confocal Optical Coherence Tomography, Reflectance Confocal Microscopy, and Ultra-High-Frequency Ultrasound: Clues for the Diagnosis of Hidrocystomas.

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.

Line-field confocal optical coherence tomography of basal cell carcinoma: A retrospective study on diagnostic performance.

Introduction: Line-field confocal optical coherence tomography (LC-OCT) represents one of the newest non-invasive in vivo skin imaging techniques. Previous studies described morphologic criteria of basal cell carcinoma (BCC) under LC-OCT examination. Preliminary data on LC-OCT diagnostic performance for BCC have recently been published but showed only a modest improvement compared to dermoscopy, possibly due to study limitations.
