Direct laparoscopic venous sampling to diagnose a small Sertoli-Leydig tumor.

BACKGROUND: Sertoli-Leydig cell tumors (SLCT) constitute only 0.5% of all primary ovarian neoplasms. We report a unique diagnostic method (selective laparoscopic venous sampling) and a rare case of a contralateral second primary tumor. CASE: A 14-year-old female presented with hyperandrogenic complaints and an increased serum testosterone. Ovarian origin was confirmed by direct laparoscopic ovarian blood sampling. A right salpingo-oophorectomy was performed. The pathological diagnosis was SLCT of intermediate differentiation. Three years later, the patient presented again with an increased serum testosterone. A solid tumor in the left ovary was excised. The pathology was SLCT of intermediate differentiation. The patient remains disease-free.
CONCLUSIONS: Direct laparoscopic venous sampling is used to diagnose a small SLCT in a teenage patient.
