PANUVEAL MALIGNANT MESENCHYMOMA

Intraocular malignant mesenchymal tumors are very rare, and only a few case reports of such primary and metastatic tumors have been reported . We report a case of a malignant mesenchymoma involving the entire uv eal tract. A 21-year-old woman presented with a tumor on the whole iri s of the right eye, which caused intractable glaucoma. Upon enucleatio n of the eye, a very anaplastic tumor was found to occupy the whole uv eal tract; its features were compatible with a tumor of mesenchymal or igin, including rhabdomyosarcomatous and liposarcomatous characteristi cs. Choroidal osteoma was a coincidental finding. The histologic findi ngs of the tumor were of two types of malignant mesenchymal tumors, an d therefore the diagnosis of malignant mesenchymoma was made. This is to our knowledge the first tumor of its kind to be reported intraocula rly.
