Ring-Shaped Leiomyoma of the Ciliary Body

Abstract

Purpose: Ciliary body mesectodermal leiomyoma is a rare, benign smooth muscle tumor that typically presents in women in the second to fourth decade of life. The diagnosis is typically based on clinical color, funduscopic appearance, transillumination properties, and B-scan ultrasonography. Methods: We present a patient with a 360° ciliary body mass with transillumination and ultrasonographic properties consistent with a ring melanoma. Results: This case emphasizes the difficulty in differentiating the benign leiomyoma from similar appearing malignant tumors such as melanoma. Conclusion: The eye was enucleated and the diagnosis was ring-shaped leiomyoma.

Intraocular myofibroblastoma tumour of the ciliary body: a case report and literature review

“…Leiomyomas are rare benign tumours, most commonly found in the uterus and alimentary tract [ 16 ]. On light microscopy analysis, the tumours are typically composed of interlacing bundles of spindle cells with blunt-ended oval nuclei, moderate amounts of eosinophilic fibrils in the cytoplasm, and intracellular myoglial fibrils [ 17 ]. Leiomyomas consistently express SMA, but do not tend to express ALK, S-100, or HMB-45 [ 18 ].…”

Inflammatory Myofibroblastoma Tumor of Intraocular Ciliary Body: A Case Report and Literature Review

“…Leiomyomas are rare benign tumors and commonly found in the uterus and alimentary tract [14].Light microscopically, the tumors are typically composed of interlacing bundles of spindle cells with blunt-ended oval nuclei, moderate amounts of eosinophilic brillation cytoplasm, and intracellular myoglial brils [15]. Leiomyomas are most consistently reactive to SMA and uniformly negative for staining with ALK, S-100, and HMB-45 [16].…”
