Abstract:

Introduction: Malignant müllerian tumors usually originate from the female genital tract as mϋllerian ducts develop during embryogenesis to form fallopian tubes, uterus and the upper third of the vagina. An extragenital origination occurs infrequently, but it has been mainly described in the peritoneum or retroperitoneum.Case
Presentation: We report the case of a 47-years old woman presented with thoracic pain progressively worsening and cough. A chest CT revealed right pleural effusion and a paramediastinic nodule. She underwent a video-assisted-toracoscopy with pleural biopsies. The immunohistochemical profile observed, particularly the positivity for WT-1 and PAX-8, together with the negativity of other lineage-specific markers allowed us to lead to the diagnosis of Primary Müllerian tumor of the pleura.
Discussion: PAX8 is a very useful marker for diagnosing carcinomas of müllerian origin. Besides, our patient received chemotherapy with carboplatin-paclitaxel and bevacizumab followed by bevacizumab maintenance, achieving a long lasting stable disease. To our knowledge, this is the second case of primary pleural müllerian tumor up to now report in the literature.
