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.

Tumor‐Derived Exosomal piR‐hsa‐28212 Promotes Lymphatic Metastasis in Breast Cancer

Cancer Science, EarlyView.
Breast cancer–derived exosomal piR‐hsa‐28212 promotes lymphangiogenesis and lymph node metastasis by activating VEGFC/VEGFR3 signaling. It stabilizes TBX1 mRNA in lymphatic endothelial cells and METTL3 protein in tumor cells, enhancing VEGFR3 expression and VEGFC secretion.

Adequacy of Single Random Skin Biopsy With Subcutaneous Sampling for the Diagnosis of Intravascular Lymphoma

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Background Random skin biopsy (RSB) is a valuable method for diagnosis of intravascular lymphoma (IVL). Previous studies have performed RSB at multiple locations. This study aimed to evaluate the adequacy of a single RSB site and the appropriate depth of the biopsies for diagnosing IVL. Methods The study included 209 patients who underwent RSB

Diffuse CD30‐Positive Cutaneous Infiltrate in a Clinically Suspected Hidradenitis Suppurativa Lesion: Histopathologic and Diagnostic Challenges

Journal of Cutaneous Pathology, EarlyView.
ABSTRACT Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder affecting apocrine gland–bearing areas. We report a 38‐year‐old male with a lesion in the left axilla, initially clinically interpreted as HS and resistant to antibiotics.
