Abstract:
Pigmented villonodular synovitis (PVNS) is a distinct but rare clinical entity often presents late with a diagnostic difficulty. Its non-specific manifestations require exclusion of several chronic inflammatory disorders and other humorous lesions but all investigations including highly predictive magnetic resonance imaging (MRI) and arthroscopic examination are non-diagnostic demanding confirmatory tissue biopsy. A typical case of such lesion is presented to highlight some potential difficulties.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
