We present a rare male fetus with karyotype of mosaic 45,X that comprises two types of aberrant Y chromosomes arising de novo (Yq12 deletion and isodicentric Yq11.22). Both types of the aberrant Y chromosomes lack the AZFc region which are expected to result in oligospermia but unaffected male external genitalia. ⋯ Additional molecular cytogenetics tools including fluorescence in situ hybridization (FISH) and multicolor banding (mBAND) were performed, which help resolving the discrepancy and delineated the composition of the aberrant Y chromosomes. This report highlighted the importance of incorporating multiple genetic technologies for accurate characterization of complex chromosomal rearrangements, which aid in the prenatal diagnosis and genetic counseling.

Intravascular leiomyomatosis (IVL) is relatively rare. The optimal surgical method and long-term outcomes are not completely understood. ⋯ One-stage operation to completely remove IVL is feasible and with good long-term outcomes, which is recommended if the patient can tolerate the operation. Concomitant intrapulmonary tumors can be followed up watchfully except when associated with pleural effusion or the pathology indicating trend of increasing malignancy.

Planning dental extractions for Taiwanese patients on antithrombotic therapy remains controversial. This study aimed to examine management of dental extraction in patients on warfarin and antiplatelet therapy. ⋯ The study indicated that there is no need to interrupt warfarin (INR<4.0) and antiplatelet therapy before dental extractions in Taiwanese patients. A sufficient hemostasis could be obtained using local measures. This approach can save these individuals from becoming exposed to the risk of thromboembolism and the inconvenience of bridging anticoagulation with heparin.
