Three Malagasy Cases of Severe Bone Complications Revealing Primary Hyperparathyroidism

Case Reports in Endocrinology, Volume 2026, Issue 1, 2026.
Primary hyperparathyroidism (PHPT) is a metabolic disorder characterized by hypercalcemia with elevated or unsuppressed parathyroid hormone (PTH). It is rare in children but common in adults, particularly in women around the age of 50. In 85% of cases, PHPT is asymptomatic and is diagnosed following hypercalcemia and elevated PTH levels during routine ...

Rare Early Coexistence of Classic Urothelial and Small Cell Carcinoma of the Urinary Bladder

Case Reports in Urology, Volume 2026, Issue 1, 2026.
Introduction Small cell carcinoma of the bladder (SCCB) is a rare aggressive cancer, representing less than 1% of bladder cancers. Similar to small cell lung cancer (SCLC), it progresses rapidly, metastasizes early, and has a poor prognosis, complicating treatment. Unlike more common bladder cancers, SCCB often resists localized treatments and responds

Ectopic Pleomorphic Adenoma of the External Nose

Case Reports in Otolaryngology, Volume 2026, Issue 1, 2026.
Pleomorphic adenomas (PAs) are the most common benign salivary gland tumors but rarely present in ectopic locations. When ectopic PAs occur in the head and neck, they most often arise from minor salivary gland tissue of the oral or nasal cavities. PAs of the external nose are exceedingly rare, and this is the first report of a PA arising from the nasal

A case of intrathyroid parathyroid tumor that was difficult to diagnose by ultrasonography

The Ultrasound Journal, 2020
Background With advances in diagnostic imaging such as ultrasonography (US), computed tomography (CT), and 99mTc-MIBI-sestamibi (MIBI) scintigraphy, localized diagnosis of hyperparathyroidism (pHPT) has become possible with considerable accuracy. However,

Intrahepatic ectopic atypical parathyroid tumor causing primary hyperparathyroidism: a case report

Frontiers in Medicine
Primary hyperparathyroidism (PHPT) most commonly arises from cervical parathyroid pathology, with ectopic disease representing a rare entity. We report a case of PHPT diagnosed during fracture workup in a female patient who manifested persistent ...
