AIM: To investigate the frequency of torsion of @entity43 in @entity1 and adolescents. METHODS: We evaluated all @entity1 treated for @entity4134 in a tertiary care referral pediatric institution during the last 20 years. Presentation, @entity5 markers and pathology reports were evaluated. We reviewed the literature on torsion of @entity43 . RESULTS: Ninety-two @entity1 (age 6 months to 19 years), 41 of them premenarchal, were surgically treated for @entity4134 . Symptoms and signs that led to clinical investigation and subsequent surgery were not specific. Histological findings of torsioned masses showed 69 non-neoplasms and 23 @entity5 , including five malignant. Origin of the @entity5 included four @entity2971 and one sex-cord @entity5 . The morphology index score for @entity5 was > or = 7 in all five @entity1 . Tumor markers were elevated in 12 @entity1 , including four of the @entity1 with @entity5 . Complete staging was performed in three adolescents with stage Ia, IIa and IIIa of disease. We found @entity5 origin for 11 previous reported @entity1 with torsion of @entity43 , including seven germ cell and four @entity722 . CONCLUSION: @entity43 in pediatric and adolescent @entity1 occurs very rarely, but it is nevertheless possible at any stage of disease. The most common torsioned @entity43 were of germ cell origin, in both premenarchal and postmenarchal @entity1 . A torsioned @entity4134 with index > or = 7 needs to be considered as a potential @entity5 .

XXXX in childhood and adolescence.
