Can preoperative findings help to interpret neoplastic and non-neoplastic lesions of ovary and affect surgical decisions in children and adolescents?

: Antecedentes. Las masas ovaricas son frecuentes en la poblacion pediatrica. Suele realizarse cirugia conservadora de los ovarios porque la mayoria son quistes benignos o funcionales. Objetivo. Investigar que hallazgos prequirurgicos sirven para diferenciar la patologia de las lesiones ovaricas, influir en las decisiones quirurgicas y predecir la posibilidad de conservar los ovarios. Metodo. Se incluyeron pacientes operadas con diagnostico de masa ovarica. Revision retrospectiva de edad, sintomas, examen fisico, marcadores tumorales, caracteristicas radiologicas y resultados anatomopatologicos. Resultados. Durante el estudio, se operaron 98 pacientes y se incluyeron 86. Media de edad: 9,7 ± 5,62 anos. Las patologias no neoplasicas representaron el 68,6 %, las neoplasicas, el 31,4 %, la tasa de malignidad, el 4,6 %. Las neoplasias incluyeron componente solido, ausencia de torsion ovarica y diametro > 9 cm (p 9 cm were more commonly seen in neoplastic cases (p < 0.001, p < 0.001, p=0.001). Adnexal torsion was found in 30 (34.9 %) patients. Mean diameter did not differ significantly between groups with or without torsion; incidence of torsion was greater in patients with masses < 6 cm (p=0.019). Ovariansparing surgery was performed in 48 (55.8 %) and oopherectomy in 38 (44.2 %) patients. Surgical approach was affected by nature (p < 0.001) and size (p < 0.001) of the lesion; it was independent of age and presence of torsion. CONCLUSION: A purely cystic mass < 9 cm, with torsion and negative markers, orients towards a non-neoplastic mass. The presence of solid component and absence of torsion are associated with increased risk of malignancy.
