RESUMO
Mature cystic teratoma is the most common ovarian neoplasm. However, mucinous cystadenoma with teratoma has been very rarely reported in literature. This case report, which is very rare, describes a clinical entity not previously reported in literature. A 34-year-old pregnant woman presented in the 23rd gestational week with severe right lower quadrant pain. She was diagnosed with acute abdomen and was then treated surgically. During the surgical intervention, a spontaneously ruptured mass was detected in the right ovary. This was reported histopathologically as a mature cystic teratoma in collision with mucinous cystadenoma. To the best of our knowledge, this case report is the first to have identified a ruptured mature cystic teratoma in collision with mucinous cystadenoma in a pregnant woman.
