Objective: An unusual case of a patient with Löfgren syndrome peritoneal involvement by sarcoidosis.
Patient and methods: A 36-year-old woman presented with Löfgren syndrome and an increase in liver enzyme levels. An abdominal CT scan showed multiple nodules on the peritoneum mimicking peritoneal carcinomatosis. Laparoscopy was conducted with biopsy of the peritoneal nodules.
Results: Biopsy specimens from the peritoneum, liver, and bronchi showed noncaseating granulomas, and the search for tuberculosis was negative. Clinical and biological features resolved within 6 months, without therapy with steroids, while a thoracic CT scan as well as an abdominal CT scan showed no change.
Conclusion: To our knowledge, this is the first reported case of peritoneal sarcoidosis associated with Löfgren syndrome. A longer follow-up will, however, be required to assess the chronicity of the disease.
