An Unusual Presentation of Sarcoidosis Mimicking Metastatic Peritoneal Carcinomatosis A Case Report and Review of the Literature

Abstract

Sarcoidosis is a multi-organ system autoimmune disorder characterized by the presence of non-caseating granuloma formation within one or more organ systems [1]. The majority of cases present with lung involvement, however 30-50% of cases have extra-pulmonary involvement at the time of clinical presentation [2]. These extra-pulmonary manifestations typically involve the skin, lymph nodes and eyes. Rarely sarcoid can manifest in the abdomen; however, this is typically noted in the liver and spleen [3]. Peritoneal sarcoidosis is a rare manifestation of the disease with less than 50 reported cases and it can rarely mimic ovarian or primary peritoneal carcinoma with elevated CA125 levels. There are 5 reported cases reported in the literature.
