Primary malignancies presenting with multiple distant metastases include lung cancer, gastrointestinal malignancy, breast cancer, and prostatic cancer. Multiple distant metastases from follicular thyroid carcinoma (FTC) are uncommon. Cystic formation in FTC is an atypical finding in ultrasonography. The cystic formation of a thyroid nodule is usually considered a benign sonographic finding. We report the case of a 78-year-old man who presented with multiple distant metastases from an FTC with a predominantly cystic formation.

Epigenetics in autosomal dominant polycystic kidney disease.

Biochim Biophys Acta Mol Basis Dis

Autosomal dominant polycystic kidney disease (ADPKD) is the fourth leading cause of end-stage renal disease, contributing substantially to patient morbidity, mortality, and healthcare system strain. Emerging research highlights a pivotal role of epigenetics in ADPKD's pathophysiology, where mechanisms like DNA methylation, histone modifications, and non-coding RNA regulation significantly impact disease onset and progression. These epigenetic factors influence gene expression and regulate key processes involved in cyst formation and expansion, fibrosis, and inflammatory infiltration, thus accelerating ADPKD progression.

Background: A significant proportion of false positive recalls of mammography-screened women is due to benign breast cysts and simple fibroadenomas. These lesions appear mammographically as smooth-shaped dense masses and require the recalling of women for a breast ultrasound to obtain complementary imaging information. They can be identified safely by ultrasound with no need for further assessment or treatment.

Unique Presentation of Pediatric Orbital Varix.

Ophthalmic Plast Reconstr Surg

January 2025

Department of Ophthalmology, University of Kentucky College of Medicine, Lexington, Kentucky, U.S.A.

Article Synopsis
  • A 2-year-old girl developed a growing bruise-like mass in her eye socket months after an orbital injury, which was diagnosed through CT imaging as possible soft tissue contusion or hematoma.
  • Surgical removal was performed, and lab tests revealed it was an orbital varix, showing CD34+ endothelium.
  • This case is unique as it represents the first documented instance of posttraumatic orbital varix formation in children.

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterized by hypophosphatemia caused by excessive secretion of fibroblast growth factor-23 (FGF-23) by tumors. This leads to impaired bone mineralization and, ultimately, osteomalacia. The most common underlying cause is a phosphaturic mesenchymal tumor (PMT).

Multi-omic biomarker panel in pancreatic cyst fluid and serum predicts patients at a high risk of pancreatic cancer development.

Sci Rep

January 2025

Department of Surgery, Trinity St. James's Cancer Institute, Trinity Translational Medicine Institute, Trinity College Dublin, St. James's Hospital, Dublin 8, Ireland.

Integration of multi-omic data for the purposes of biomarker discovery can provide novel and robust panels across multiple biological compartments. Appropriate analytical methods are key to ensuring accurate and meaningful outputs in the multi-omic setting. Here, we extensively profile the proteome and transcriptome of patient pancreatic cyst fluid (PCF) (n = 32) and serum (n = 68), before integrating matched omic and biofluid data, to identify biomarkers of pancreatic cancer risk.
