RESUMO
PURPOSE: Solitary fibrous tumor is a rare spindle-cell tumor that usually is seen in the pleura. The orbit is one of the most common extrapleural sites. It is frequently misdiagnosed as hemangiopericytoma and is seen in older patients. We present the youngest case of this tumor, which was apparent in family photographs by age 10 and removed at age 15. The first reported echography findings are presented. METHODS: Case report and literature review. RESULTS: Solitary fibrous tumor was diagnosed by microscopy and immunohistochemical study that showed cells reactive with vimentin and CD34. CONCLUSIONS: Solitary fibrous tumor of the orbit has been diagnosed with increasing frequency in recent years as the result of improved methods of pathologic examination. It is important to be aware of this tumor and recognize that it must be included in the differential diagnosis of highly vascular spindle-cell tumors even in young children.

Uveal melanoma is the second most frequent ocular malignancy after metastasis and the most common primary ocular malignant neoplasm in adults. The diagnosis is usually made from clinical examination and ocular ultrasound. CT and MR may be helpful for further evaluation.

A 75-year-old woman who underwent implantation of an anterior-chamber intraocular lens was noted to have the lens disappear from the anterior chamber four days after surgery and reappear on the eleventh postoperative day. Ultrasound documented the position of the lens as apparently lying posterior to the sclera and anterior to the ciliary body. Extrusion through a cyclodialysis cleft superonasally was the apparent mechanism of exit and reentry. Pseudophakic dislocation is becoming increasingly common.
