Circular Skin Lesions Mimicking Blunt Trauma: A Forensic Case of Cupping Therapy.

Skin findings provide important diagnostic clues in both clinical and forensic practice, often serving as an initial trigger for evaluating the possibility of physical assault or child abuse. However, not all discolorations that resemble bruises result from blunt trauma. Cupping therapy, a traditional complementary treatment widely practiced in East Asia, can produce purplish skin discolorations caused by superficial capillary rupture from localized negative pressure. We present a forensic autopsy case of a man who died following a fall from height. During postmortem examination, multiple circular purplish discolorations were observed on his upper back, initially raising suspicion of blunt trauma or assault. However, postmortem dissection revealed no hemorrhage in the subcutaneous fat or muscle tissue beneath the lesions, and further investigation identified a history of recent cupping therapy. This case highlights the importance of recognizing cultural practices such as cupping therapy that may mimic traumatic injuries and underscores the need for careful differentiation in both forensic and clinical evaluations to avoid diagnostic errors.
