Pulsations as a Signal of Danger: A Case of Scalp Cirsoid Aneurysm.

Cirsoid aneurysms, formerly identified as arteriovenous malformations (AVMs), represent infrequent vascular anomalies primarily localized within the scalp. These anomalies are typified by the absence of interposing capillaries, giving rise to extensively vascularized, expanded conduits connecting arterial feeders and venous outflows. This report details a case of a 13-year-old male afflicted with a cirsoid aneurysm in the scalp, who presented with swelling on the left frontal region, accompanied by headache and pulsatile sensations.

Immunoglobulin G4-related chronic sclerosing sialadenitis: An emerging entity.

Chronic sclerosing sialadenitis is associated with the immunoglobulin G4 (IgG4)-related disease (RD) spectrum. IgG4-RD is a newly recognized immunomediated fibroinflammatory condition characterized by several features: a tendency to form tumefactive lesions at multiple sites, lymphoplasmacytic infiltrate, fibrosis and obliterative phlebitis. Often but not always, the serum IgG4 concentrations are also elevated.
