[The use of ultrasonographic 3D power Doppler to describe an ovarian Sertoli-Leydig cell tumor]. / Description échographique d'une tumeur ovarienne de Sertoli-Leydig à l'aide du doppler énergie tridimensionnel.

We report one case of unilateral ovarian Sertoli-Leydig tumor with intermediate grade and heterologous element, in a young woman with clinical and biological typical presentation. We discuss 2D and 3D ultrasonographic and doppler features.

[Solitary fibrous tumor of the orbit: an unusual cause of unilateral proptosis. Case report with a review of the literature]. / Tumeur fibreuse solitaire de l'orbite: une cause inhabituelle d'exophtalmie unilatérale. A propos d'un cas avec revue de la littérature.

BACKGROUND: The solitary fibrous tumor (SFT) is a spindle-cell tumor that very rarely involves the orbit. We report a new case that we compare to reports in the literature. CASE: A 72-year-old woman presented a conjunctival inflammation of the right eye developing over 5 months with progressive proptosis. Magnetic resonance imaging revealed an extraconal and homogeneous mass, which showed hypointensity on T1-weighted images and hyperintensity on T2-weighted images, without specificity. Histological examination of the lesion removed by anterior orbitotomy confirmed the diagnosis of the SFT of the orbit. The patient was doing well without recurrence after 9 months. DISCUSSION: The diagnosis of SFT is histological. It is a mesenchymal tumor. Immunohistochemically, the tumor cells are strongly positive for CD34 and vimentin. CONCLUSION: The SFT of the orbit is a very rare and generally benign tumor. It must be immunohistochemically differentiated from other spindle-cell tumors of the orbit. The treatment is a complete surgical excision, and long-term follow-up is necessary because recurrence may appear long after treatment.
