Which term refers to pinpoint hemorrhages that may indicate strangulation or asphyxia?

• A. Remains
• B. Optical
• C. Petechiae
• D. Cartilage

Answer: (C)

Petechiae are tiny pinpoint hemorrhages that occur when small capillaries rupture due to increased venous pressure or congestion. In cases of possible strangulation or asphyxia, obstruction of venous return from the head and neck raises pressure in these vessels, causing rupture and the appearance of these little red or purple spots. They’re often seen on the sclera (subconjunctival), eyelids, face, lips, or mucous membranes. Their presence supports an asphyxial mechanism in the right clinical setting, though they can occur with other conditions that raise venous pressure as well, so they’re not exclusive to strangulation.
