Abstract/OtherAbstract:
Primary uveal-tract neoplasms are extremely rare in childhood; the most common lesions found are melanocytic. We report here the case of a 7-year-old girl who underwent enucleation of the right eye with clinical suspicion of choroid melanoma as a result of a ciliary body mass that extended to the posterior chamber. Histologically, the neoplasm featured spindle cell morphology, atypia, and mitoses. The tumor expressed smooth muscle alpha actin, pan-actin HHF-35, and desmin, whereas immunohistochemistry for melanocytic markers, such as S-100, Melan-A, and HMB-45, was negative. Based on these features, the diagnosis of leiomyosarcoma of the ciliary body was firmly established. Although several leiomyomas have been reported in the literature, there are only 2 previously reported cases of primary leiomyosarcoma of the uveal tract. Immunohistochemical expression of muscle proteins allowed distinction from the most common melanocytic tumors arising in this location.
