[Stereotaxic fine-needle aspirations of clinically latent breast cysts: an efficient and neat procedure]. / Les cytoponctions sous stéréotaxie des kystes mammaires infracliniques: une procédure efficace et élégante.

The purpose was to evaluate the interest of stereotaxic fine-needle aspiration for round opacities when the ultrasound and echoguided punctures are inefficient; especially when women are under menopausal hormonal replacement therapy. Sixty stereotactic guided fine-needle aspirations detected by mammography have been performed between january 1990 and august 1996. The stereotaxic procedure is performed with a DMR unit (GE with Stereotix II). Stereotaxic views are done to verify needle position. After aspiration, cytologic examination is realised. Cystic fluid was always obtained and cytologic examination proved benign cysts in all cases. In 50 cases, cysts completely disappeared. There were 2 relapses that received after a second. This method is reliable for evaluation of non palpable mammographically detected opacities. The use of this technique spares the patient a surgical biopsy. This procedure enables women under menopausal hormone replacement therapy to continue the treatment.
