Prospective subtyping of head and neck basal cell carcinoma by dermoscopy and handheld RCM

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Handheld reflectance confocal microscopy, alone or with dermoscopy, increases specificity, maintains high sensitivity and improves diagnostic confidence for head and neck basal cell carcinoma. It may offer a non‐invasive alternative to confirmatory biopsies when planning micrographically controlled surgery in clinically high‐risk cases.

Line‐Field Confocal Optical Coherence Tomography (LC‐OCT) of Pilomatricoma

Pediatric Dermatology, EarlyView.
ABSTRACT Pilomatricoma is a benign cutaneous tumor of hair matrix origin, often presenting in children as a slow‐growing, firm, colored nodule. Line‐field confocal optical coherence tomography (LC‐OCT) is a novel imaging method that enables non‐invasive, quasi‐histologic visualization of the skin.

Nevus of Ota – an intraoral presentation: a case report

Journal of Medical Case Reports, 2019
Background Nevus of Ota or “oculodermal melanocytosis” is a rare congenital hamartoma of dermal melanocytes causing a blue-gray hyperpigmentation of the eye and surrounding structures. The condition, originally described by Ota and Tanino in 1939, mainly

Illuminating Connections: Exploring the Dynamic Relationship Between Phototherapy and the Skin

Pediatric Dermatology, EarlyView.
ABSTRACT The neonatal period represents a critical window for skin barrier maturation, microbial colonization, and immune development. As such, early‐life exposures may exert lasting effects on dermatologic and systemic health. A common early‐life exposure is blue light phototherapy (BLP), a life‐saving treatment for neonatal hyperbilirubinemia ...

PRAME promotes invasion and metastasis of salivary adenoid cystic carcinoma by regulating RARα stability via the cullin2 ubiquitin‐proteasome system

Clinical and Translational Medicine, Volume 16, Issue 9, September 2026.
PRAME promotes SACC invasion and metastasis by inducing EMT via Twist1 upregulation and by destabilizing RARα through Cullin2‑mediated ubiquitination, a mechanism that may limit ATRA efficacy. In vivo, PRAME enhances subcutaneous growth and lung metastasis, highlighting its oncogenic role in SACC.
