Evolving Pathology of Anaplastic Thyroid Carcinoma: Integrating Morphology, Immunohistochemistry, and Molecular Insights

Cancer Science, EarlyView.
Schematic overview of progression from differentiated thyroid carcinoma (DTC) to anaplastic thyroid carcinoma (ATC). ATC primarily develops via two pathways: the BRAF p.V600E‐mutated papillary thyroid carcinoma (PTC) pathway and the RAS‐mutated pathway. The origin and progression of BRAF/RAS‐wildtype ATC remain unclear.

Oncogenic BRAF and KRAS Promote Global DNA Hypomethylation Through a Directed Pathway That Upregulates TET3

Cancer Science, EarlyView.
Oncogenic BRAF and KRAS promote global DNA hypomethylation through a directed pathway that increases the levels of TET3, which helps drive tumorigenesis. ABSTRACT Aberrant epigenetic modification is one of the characteristics of the cancer genome.

Malignancy in Pediatric Hyperfunctioning Thyroid Nodules: A Case Report and Literature Review

Clinical Endocrinology, EarlyView.
ABSTRACT Background Thyroid nodules are rare in children but carry a markedly higher risk of malignancy compared to adults (20%–26% vs. 5%). Hyperfunctioning thyroid nodules are exceptionally uncommon in the pediatric population and are typically benign.

Rare Secondary Neoplasms Arising in Epidermal Nevus: A Case Series and Literature Review

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Malignant transformation is known to occur with many nevi, such as nevus sebaceus. However, cases of secondary tumors developing in an epidermal nevus (EN) are rare, with only a few case reports documented in the literature. We present three unique cases of syringocystadenoma papilliferum (SCAP), syringofibroadenoma, trichilemmoma, and basal ...

A Rare Case of Cutaneous Crystal‐Storing Histiocytosis With Kappa Light Chain Restriction and Unusual BCL6 Expression

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Crystal‐storing histiocytosis (CSH) is a rare histopathologic phenomenon characterized by the accumulation of crystalline material within histiocytes, most often associated with lymphoplasmacytic or plasma cell neoplasms. Cutaneous involvement is uncommon and may present diagnostic challenges.

Eccrine Squamous Syringometaplasia Mimicking Acute Cutaneous GVHD in a Pediatric HSCT Recipient: Case Report and Brief Review of the Indexed Literature

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Eccrine squamous syringometaplasia (ESS) is an uncommon reactive alteration of eccrine ducts, most often reported in oncologic and transplant settings, where it may clinically mimic acute cutaneous graft‐versus‐host disease (GVHD). We describe a 3‐year‐old boy with chronic granulomatous disease who developed a diffuse erythematous eruption 6 ...

Superficial Ewing Sarcoma of the Rectum: A Case Report and the Utility of Molecular Diagnostics

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Ewing sarcoma is an undifferentiated small round cell sarcoma that most commonly presents as a malignant bone tumor in pediatric and young adult patients. The diagnosis is typically confirmed by molecular genetic identification of a fusion protein, most commonly involving members of the FET and ETS gene families.

Dermatologic Toxicities Associated With Novel Pan‐RAS/RAF Inhibitors

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Background The mitogen‐activated protein kinase (MAPK) pathway plays a key role in cell‐cycle regulation and tumor progression in cancer. Dermatologic toxicities (DTs) to newer pan‐RAS (RMC‐6236) and pan‐RAF (LXH254/naporafenib) inhibitors are emerging.
