Objective: Mesectodermal leiomyoma of the ciliary body is a rare tumor with, to our knowledge, only 15 cases reported in the literature. It has a neural histopathologic appearance and a presumed origin from neural crest.
Design: Case report.
Results: Two cases of mesectodermal leiomyoma with histopathologic and immunohistochemical confirmation are reported.
Conclusions: For the second time, we were able to demonstrate expression of neural immunohistochemical markers in this tumor.

Mesectodermal leiomyoma of the ciliary body is a rare benign tumor, showing both neurogenic and myogenic characteristics. This tumor typically shows predilection for women of reproductive age. Because it is almost impossible to clinically distinguish this tumor from malignant melanoma, unnecessary eye enucleations have been unfortunately performed.

Purpose: To describe the demographic profile, clinical and histopathologic features, and treatment of ciliary body tumors.
Study Design: Retrospective, observational case series.
Methods: Thirty-two patients (32 eyes) with ciliary body tumors diagnosed histopathologically at Tokyo Medical University Hospital between 1994 and 2017 were retrospectively reviewed.

Introduction: Mesectodermal leiomyoma of the ciliary body is a benign rare tumor that rarely presents acutely with a complicated clinical course.
Presentation Of Case: We are reporting a 39-year-old healthy female who presented with subacute blurred vision in her right eye secondary to a ciliary body mass. Initial fine needle aspiration biopsy ruled out a melanoma but the patient meanwhile experienced rapid complicated growth of the mass with vision loss, for which her right globe was eventually enucleated.

Purpose: We report a case of acutely presenting mesectodermal leiomyoma of the ciliary body in a 29-year-old female who reported waking up with swollen eyelids of the right eye and light-perception vision. The affected eye had elevated intraocular pressure, a flat anterior chamber, and a pale, round mass arising from the nasal ciliary body, invading the angle and protruding into the visual axis posterior to the lens. Within days, the visual acuity decreased to no light perception.

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.
