Osteonevus of Nanta—A Rare Case Report of a Cellular Blue Nevus with Ossification

Reports
Background and Clinical Significance: Osteonevus of Nanta is a rare histological phenomenon characterized by bone formation within a benign melanocytic nevus, most commonly in intradermal nevi of the head and neck.

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.

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 ...

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

Understanding Exosomes in Hair Regeneration

Periodontology 2000, EarlyView.
Abstract Background Alopecia is a prevalent condition correlated with significant psychosocial challenges, while contemporary treatments exhibit variable efficacy, require extended use, and may cause adverse effects. This review aimed to comprehensively assess exosome‐mediated interventions as a novel cell‐free regenerative approach for hair ...

Deep penetrating nevus: a case report and brief literature review

Diagnostic Pathology, 2006
Background - Deep penetrating nevus (DPN) is a distinct variant of melanocytic nevus and remains a histopathologic challenge to pathologists because of its resemblance to blue nevus, malignant melanoma, pigmented Spitz nevus, and congenital melanocytic ...

Functional validation of driver mutation‐specific uveal melanoma biomarkers: role of COL9A3 in cancer cell plasticity

The Journal of Pathology, Volume 270, Issue 2, Page 226-240, October 2026.
Abstract Uveal melanoma (UM) is a deadly ocular malignancy with well‐described genetic alterations that predict disease outcome. However, our current understanding of the biological underpinnings of high‐risk uveal melanoma progression remains relatively limited. Using RNA expression profiles from 250 patients with UM, we identified 12 novel biomarkers

Case Report: An unexpected case of tumor regression in blue nevus melanoma following COVID-19 infection

Frontiers in Immunology
Blue nevus is a benign melanocytic lesion that appears as a blue or dark mole due to the presence of melanin deep within the skin. In rare cases melanoma can arise from this association with blue nevus, and entity termed blue nevus melanoma (BNM).

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.
