RESUMEN
Purpose: To investigate whether or not intracytoplasmic sperm injection (ICSI) using spermatozoa extracted from testis (TESE-ICSI) is a more effective treatment than ICSI with ejaculated spermatozoa (EJ-ICSI) for primary ciliary dyskinesia (PCD). Methods: We reported a case of PCD in which we performed TESE-ICSI after repeated failure of EJ-ICSI. Together with data from previous case reports, we compared the fertilization rate and pregnancy outcome of TESE-ICSI and EJ-ICSI. Results: In our case, TESE-ICSI improved the morphology of spermatozoa and fertilization rate. However, the outcome was only a biochemical pregnancy. According to the analysis combined with previous reports, there was no difference in the fertilization rate and pregnancy outcome parameters between TESE-ICSI and EJ-ICSI. Conclusions: TESE-ICSI for PCD may improve the fertilization rate compared to EJ-ICSI. However, it does not necessarily improve the pregnancy outcome for a patient with primary ciliary dyskinesia.
RESUMEN
Malignant transformation is an unusual complication of mature cystic teratomas. Squamous cell carcinomas and adenocarcinomas are predominant among these malignant tumors. We present a 70-year-old Japanese woman with a giant ovarian tumor (30 x 23 x 9 cm) and multiple peritoneal dissemination. The huge tumor was filled with necrotic and fatty tissue and coagula accompanied with hair balls histologically diagnosed as undifferentiated carcinoma with multinucleated giant cells arising in an ovarian mature cystic teratoma. The residual disseminated tumors grew very rapidly and occupied the whole abdominal cavity again 3 weeks after the surgery. The patient died 5 weeks after the operation.
