Pediatric Fetal Rhabdomyoma Representing as Acute Mastoiditis: A Case Report and Literature Review

Rhabdomyomas are rare benign tumors. Most extracardiac rhabdomyomas are found in the head and neck region, especially in the pharynx and larynx. Herein, we have described the case of a 1-year-old boy presenting with recurrent otorrhea and postauricular swelling. His symptoms were due to a mass that was histologically diagnosed as fetal rhabdomyoma (FR). Here, we report the first case of FR in the postauricular area. Clinicians should keep in mind the possibility of FR if a child presents with external auditory canal mass associated with recurrent otorrhea and signs of mastoiditis.
