Abstract
BackgroundStruma ovarii is a variant of monodermal teratoma, consisting of morphologically benign, atypical, or frankly malignant thyroid tissue. Morphologic features may or may not correlate with biologic behavior. Albeit this case report is not unique, ovarian tumor developed with peritoneal dissemination and bone metastasis, which is highly unlikely clinical complication. Additionally, we summarized previously cases of struma ovarii with an emphasis on correlation between morphological appearances, clinical course and providing treatment. Case presentationWe present the 38-year-old patient who was hospitalized for ovarian tumor. The diagnostic laparoscopy revealed lesions of peritoneum, sigmoid serosa and omentum and left ovarian mass. We diagnosed left ovarian mature teratoma without struma tissue and metastatic lesions with struma morphology which can be related to her history of left ovarian struma in 2016. Taking into account the metastatic lesions revealed in 2020, the tumor removed in 2016 was assessed as highly differentiated follicular carcinoma arising in struma ovarii. ConclusionsPrediction of biologic behavior of struma ovarii is still to be to diagnostic challenge, therefore multidisciplinary approach including clinical a n d laboratory findings, radiologic details and histopathological features is required. Providing additional data, the present case report contributes to expending the knowledge of these peculiar neoplasms.
