The studied sample did not achieve satisfactory growth results, as in other published series. Our findings might be improved by starting treatment earlier, and with doses individualised according to patient characteristics.
RESUMENEl tumor de los cordones sexuales con túbulos anulares es una neoplasia del estroma gonadal muy infrecuente. Representa el 0,05-0,6% de todos los tumores ováricos, según series. Se presenta un caso especialmente inusual, en una niña de 6 años, detectado a raíz de una pubertad precoz periférica isosexual. Su interés radica en que no se halló ninguna masa anexa al ovario, sino únicamente una asimetría gonadal, sin signos radiológicos de malignidad. Se realizó una salpingo-ooforectomía unilateral con linfadenectomía pélvica y paraaórtica ipsilateral, por vía laparoscópica, tras confirmarse la presencia de células tumorales en la biopsia intraoperatoria. La evolución posterior de la paciente fue favorable.
Palabras clave: tumores de los cordones sexuales y estroma de las gónadas, pubertad precoz, inhibina B.ABSTRACT Sex cord tumor with annular tubules is an extremely uncommon gonadal stromal neoplasm. It represents 0.05-0.6% of all ovarian tumors, according to series. An unusual case is presented in a 6-year-old girl, detected as a result of an isosexual peripheral precocious puberty. The highlight of this case is that no mass attached to the ovary was found, but only a gonadal asymmetry without radiological signs of malignancy. After confirming the presence of tumoral cells by intraoperative biopsy, unilateral salpingo-oophorectomy with ipsilateral para-aortic and pelvic lymphadenectomy was performed. Afterwards, the evolution of the patient was favorable.
INTRODUCCIÓNEl tumor de los cordones sexuales con túbulos anulares (TCSTA) es una neoplasia del estroma gonadal extremadamente infrecuente. Constituye el 0,05-0,6% de todos los tumores ováricos, según series.
