A 55‐year‐old woman with a 10‐year‐old mammary prosthesis developed Sjögren's syndrome (sicca syndrome, anti‐Ro, and salivary gland biopsy positivity) for 4 years and rupture of one side of the prosthesis for 1 year. After 3 months of moderate abdominal pain in the right hypochondrium, hyperthermia, pruritus, chronic fatigue, and myalgia, she was admitted to the emergency department. Physical examination showed pain on palpation of the right hypochondrium. Regarding laboratory findings, hepatic enzymes were elevated (alanine aminotransferase, 68 UI/L [reference value, 0‐31 UI/L]; aspartate aminotransferase, 50.6 UI/L [reference value, 0‐32 UI/L]) and anti‐mitochondrial antibodies were positive (1:80). The viral infection panel and anti–smooth muscle antibody were negative. Abdominal magnetic resonance imaging revealed cholecystitis and abnormal hepatic enhancement without focal lesions. On the basis of these findings, cholecystectomy and hepatic biopsy were performed and revealed hepatic infiltration by silicone
