RESUMO
Odontogenic myxofibroma of the temporomandibular joint (TMJ) is a rare tumour; moreover, primary splenic angiosarcoma (PAS) in paediatric patients is extremely rare. We report on a 15-year-old boy who presented with right TMJ swelling and subsequently developed epigastric and right upper quadrant pain. The TMJ swelling proved to be odontogenic myxofibroma and the abdominal pain was a result of primary splenic angiosarcoma with hepatic metastasis. We report for the first time the synchronous presentation of PAS and odontogenic myxofibroma in a paediatric patient, and we describe the radiological features along with the histological diagnosis and clinical outcome. Uptake in (18)F-2-fluoro-2-deoxy-D-glucose positron emission tomography is also described for the first time for both these tumours.

This is a prospective study evaluating 28 patients who were suspected to have ectopic pregnancy. Frozen section Pipelle endometrial biopsy was performed as an outpatient procedure to look for the presence of chorionic villi in the specimen. The sensitivity of the frozen section endometrial biopsy in detecting the presence of chorionic villi was 13.3% and the specificity was 100%. The positive predictive value was 100% and the negative predictive value was 50%. We concluded that frozen section endometrial biopsy was not helpful in predicting intrauterine gestational process; therefore, it has a limited application in patients suspected to have ectopic pregnancy.
