Statin-Induced Necrotizing Autoimmune Myopathy: An Uncommon yet Challenging Complication of Statin Use.

Statin-induced necrotizing autoimmune myopathy (SINAM) is a rare, disabling, and potentially life-threatening complication of statin use. Although not fully understood, a prevailing hypothesis proposes that statins induce molecular changes in 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR), leading to the formation of anti-HMGCR antibodies. The subsequent myofibre necrosis is expressed as progressive and persistent proximal muscle weakness and elevated creatine kinase (CK) levels.

Masson's Tumour: A Rare Cause of Cervical Mass.

Unlabelled: Masson's tumour, also known as intravascular papillary endothelial hyperplasia, is a rare non-neoplastic lesion of vascular origin, caused by an excessive reactive proliferation of endothelial cells in normal blood vessels or vascular malformations. It can affect any part of the body, presenting most frequently in the vessels of the head, neck and upper extremities. The authors describe the case of a 76-year-old female patient presenting an anterior cervical mass, measuring 2×2 cm, which was mobile, tender and slightly painful with no alteration of the overlying skin.

Immune Thrombocytopenia: A Rare Presentation of Pulmonary Sarcoidosis.

Unlabelled: Thrombocytopenia may be the initial presentation of sarcoidosis, which is a systemic granulomatous disorder. Various pathophysiological mechanisms have been identified. Immune thrombocytopenia often has a severe presentation but may respond favourably to immunosuppressive therapy.
