Abdominal Sarcoidosis May Mimic Peritoneal Carcinomatosis

Abstract EN

Sarcoidosis is a multisystem inflammatory disorder of unknown etiology.

It shows a great variety of clinical presentation, organ involvement, and disease progression.

Lungs and lymphoid system are the most common sites involved with a frequency of 90% and 30%, respectively.

Extrapulmonary involvement of sarcoidosis is reported in 30% of patients and abdomen is the most frequent site.

Furthermore, peritoneal involvement is extremely rare in sarcoidosis.

The case presented here described peritoneal manifestations of sarcoidosis without involvement of lungs.

A 78-year-old woman possessing signs of malignancy on blood test and abdominal magnetic resonance imaging underwent laparatomy with a suspicion of ovarian malignancy.

The macroscopic interpretation during surgery was peritoneal carcinomatosis.

Total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal biopsies, total omentectomy, and appendectomy were performed.

Final histopathological result revealed the diagnosis of sarcoidosis.

Clinicians must keep in mind that peritoneal sarcoidosis can mimic intra-abdominal malignancies.
