Objective: To report a case of sarcoidosis post-treatment of adenocarcinoma of the uterine cervix. Case: A 38-year-old, G1P1A0 was admitted to the present hospital for palliative treatment of Stage IB1 adenocarcinoma of the uterine cervix with hepatic recurrence posthysterectomy. The patient initially received six cycles of cisplatin and taxol leading to complete remission. Six months after the palliative treatment, MRI revealed slight changes in the pelvis, suggestive of the involvement of the left iliac lymph node. Anatomo-pathological results after lymphadenectomy showed tumor recurrence. Following additional pelvic radiotherapy, the patient remained asymptomatic. However, oncologic control performed three months later exposed mediastinal lymphadenopathy and new biopsy revealed sarcoidosis. The patient remained asymptomatic in the subsequent follow-ups without evidences of tumor recurrence. This study shows the importance of differential diagnosis during the oncologic monitoring of cervical cancer patients to avoid unnecessary treatments at the expense of better therapeutic options.
