Tumor de células esteroideas sin otra especificación: reporte de un caso

Ovarian steroid cell tumours are an uncommon cause of virilisation. They may originate from the stroma or sex cords; sometimes the tumour lineage is unknown, in which case the tumour is described as “not otherwise specified”. We report the case of a patient with signs of rapidly progressive virilisation, suggestive of ovarian origin. Imaging tests were negative. After surgical intervention, the presence of microscopic tumour markers positive for steroid cells was observed.
