Epitheloid leiomyoma is a very rare subtype of benign mesothelial tumors of the bladder. A 46-year-old female patient presented to our hospital with prolonged dysuria, frequency, and recurrent urinary tract infections. Bimanual examination revealed a mobile, round mass in bladder. There was a round hyperdense intravesical mass near bladder neck in computed tomography (CT) scan that was compatible with her magnetic resonance imaging (MRI). A well defined 3 × 4 centimeter mass was seen in superolateral part of bladder neck during cystoscopy. The patient underwent partial cystectomy and histopathologic findings confirmed the diagnosis of epithelioid leiomyoma. The patient's followup was uneventful in a period of 2 years. Size and anatomic location of this tumor were major factors that affect on treatment.

Three cases of embryonal rhabdomyosarcoma in the middle ear and mastoid in children are presented. Diagnosis was confirmed by histopathology. A multidisciplinary approach employing surgery, chemotherapy and radiation therapy is the method of choice in the management of this rare and highly lethal condition.
