CASES: Initially, we searched the literature to identify and retrieve any evidence related to this unique form of purple-maroon discoloration of the buttocks. No evidence was found. To illustrate the condition, we compared 4 cases of what we have labeled chronic tissue injury to 6 patients with purple-maroon discoloration of the buttocks from different causes. CONCLUSION: Chronic tissue injury is characterized by a persistent purple-maroon discoloration located on the fleshy portion of the buttocks that does not improve or deteriorate. Unlike other causes of purple discoloration such as deep tissue pressure injury, there is minimal change in the discoloration over time. Additional research is needed to further our understanding of the histopathology of this phenomenon.
