    Sarcoidosis and Sarcoid Reactions in Endometrial Cancer Cases Mas-querading Advanced Stage Malignancy

    Background: Sarcoidosis is usually diagnosed by ruling out other granulomatous inflammatory diseases. Rarely, it may be suspected with a pathological examination after surgical intervention for another disease. The sarcoid reaction is noninfectious granulomatous lymphadenitis, which can occur at nodes draining a neoplasm. We demonstrated granulomatous lesions masquerading metastasis by Positron Emission Tomography/Computed Tomography (PET/CT) in endometrial cancer. We presented two cases of endometrial cancer with sarcoidosis and sarcoid-like reactions because of their challenging clinical and radiological findings. Cases: In case 1, there was diffuse granulomatous inflammation (no metastasis) in lymph nodes (n=92) and giant cells containing calcifications (Schaumann bodies). In case 2, PET/CT revealed hypermetabolism with malignancy suspicion in the pelvic lymph nodes (maximum standardized uptake value= 13) and pathological evaluation reported a 4.5 cm tumor within the uterine cavity without any nodal metastasis. Results: PET/CT has no role in the evaluation of differential diagnosis between granulomatous lymphadenitis and metastatic disease. Conclusion: Granulomatous lesions might mimic the metastasis of coexisting malignant diseases.
