Double trouble: orbital rhabdomyoma with trichinellosis.

Abstract

Rhabdomyoma of the orbit is a rare tumor with very few cases reported in the literature. We herein describe a 5-year-old boy who presented to us with a deviation of his left eye. Magnetic Resonance Imaging (MRI) showed a well-defined homogeneous intraconal mass in the superomedial aspect compressing the optic nerve. An excision biopsy was performed and the diagnosis of rhabdomyoma was confirmed on histopathology and immunohistochemistry with a coincidental finding of Trichinella spiralis larvae within the excised specimen. We report this phenomenon in two rare diseases with a predilection for striated muscle occurring simultaneously in a single patient.
