Diagnostic error, benign infiltrative pseudotumor or malignant primary lymphoma of cervix: case report
Abstract
Background: Although cervical malignancy rate had grown up in recent years, primary cervical lymphoma is so rare. It must be high index of suspicious for primary cervical lymphoma diagnosis in patient with malignancy-like signs and symptoms for early detection. Primary cervical lymphoma has no standard treatment or follow-up protocol; so the management still is in doubt and based on previous case reports. In the other hand, the precise prognosis of patient is undetermined. In the present study, a case of primary cervical lymphoma is presented which was misdiagnosed at first. The patient accurate diagnosis was made at last due to multidisciplinary team working. Case presentation: A 51-year-old woman, gravida 2, para 2, presented with complaint of abnormal vaginal bleeding and discharge, with no abnormal finding in cervical cytology and sonography, so uneventfully a diagnostic error had happened in the assessment of her. After several months and multiple different treatment, the patient referred to the Oncology Department of Obstetrics and Gynecology Center, Ghaem Hospital, Mashhad, Iran in May 2017. Re-assessment was performed by biopsy and imaging, and the final pathologic diagnosis of diffuse large B-cell non-Hodgkin's lymphomas was confirmed. Conclusion: Primary cervical lymphoma is an uncommon malignancy; the diagnosis could be missed simply by low suspicious due to low accuracy of Pap smear and imaging in this situation. So an accurate evaluation and pelvic examination, high suspicious and close communication between clinician and pathologist are needed. By timely diagnosis of patient in early stage and appropriate approach, the prognosis could be excellent most of the time.
