The autosomal dominant Birt-Hogg-Dubé syndrome is known to be associated with skin, lung and kidney lesions. It is caused by heterozygous germline mutations in the folliculin gene and has a high penetrance. We report the case of a 51 year old woman with Birt-Hogg-Dubé syndrome who presented with a laryngeal mass. Imaging confirmed a mass centered on the piriform sinus and following excision histological examination confirmed the lesion was composed of polygonal cells with abundant eosinophilic cytoplasm consistent with a rhabdomyoma...

Adult extracardiac rhabdomyomas are rare benign mesenchymal tumor arising from skeletal muscle. While they are often located in the larynx and pharynx, the incidence in the parapharyngeal area is extremely rare with only 1 documented cytology case report to date. We report a case of an adult extracardiac rhabdomyoma in the parapharyngeal space diagnosed cytologically with subsequent histologic confirmation. The patient is a 57-year-old man with history of weight loss, hematuria, dysphagia, and airway encroachment...

Introduction Rhabdomyoma is a rare benign tumor derived from skeletal muscles. Laryngeal rhabdomyomas are even rarer, with only approximately 40 reported cases in world literature. Laryngeal rhabdomyomas usually are seen as masses covered by mucosa. They are often solitary asymptomatic tumors, but symptoms such as hoarseness can occur. The radiologic features are usually those typical of benign neoplasms, showing well-delineated borders. The differential diagnoses for laryngeal masses include cysts, laryngoceles, and benign and malignant neoplasms...

Background. Adult rhabdomyoma is a rare benign tumour with the differentiation of striated muscle tissue, which mainly occurs in the head and neck region. Twenty-six cases of multifocal adult rhabdomyoma are documented in the literature. Method. We report a 55-year-old male with simultaneous diagnosis of 7 adult rhabdomyomas and review the literature of multifocal adult rhabdomyoma. Result. Review of the literature revealed 26 cases of multifocal adult rhabdomyoma, of which only 7 presented with more than 2 lesions...

The extracardiac juvenile rhabdomyoma is extremely rare in the field of Otorhinolaryngology. The tumour usually arises from the soft tissue of the face or from mucosal sites, especially the oropharynx and the oral cavity but only sporadic endolaryngeal cases have been described in literature so far with predominance of young males. Here, we describe the very rare case of endolaryngeal extracardiac juvenile rhabdomyoma in a 42-year-old male. Clinical examination showed a mass of the right vocal cord, resembling a cystic lesion...

A 3-year-old, female spayed Australian Shepherd dog was presented to Veterinary Healthcare Associates in Winter Haven, FL with a history of respiratory stridor, difficulty swallowing, and a change in bark for approximately 3 months. Radiographs revealed a soft tissue mass caudal to the epiglottis. Oral and computerized tomographic (CT) examinations were performed under general anesthesia and revealed a small firm mass in the caudal larynx on the right side. Cytologic evaluation of a fine-needle aspirate of the mass revealed cells consistent with a rhabdomyoma, oncocytoma, or granular cell tumor...

Tuberous sclerosis (TSC) is an autosomal-dominant genetic disease characterized by a spectrum of pathologic manifestations involving skin, brain, kidney, and heart. These manifestations include neuroectodermal, mesodermal, and skin lesions as well as a variety of associated tumors and hamartomas. We report an 11-year-old male with previously diagnosed TSC who presented with a laryngeal mass shown on histology to be fetal cellular rhabdomyoma. Cardiac rhabdomyomas are common in TSC patients, but to our knowledge, the association between TSC and extracardiac rhabdomyomas has not been previously reported...

Rhabdomyomas are rare benign mesenchymal tumors with skeletal muscle differentiation. They are less commonly encountered than are their malignant counterparts, rhabdomyosarcomas. Rhabdomyomas fall into 2 general categories: cardiac and extracardiac types. Extracardiac rhabdomyomas are among the rarest tumors in humans and can be subclassified as fetal, juvenile, and adult types depending on the individual tumor's degree of differentiation by light microscopy. Adult extracardiac rhabdomyoma has a strong predilection for occurrence in the head and neck, mainly in the area of larynx and pharynx...

INTRODUCTION: Rhabdomyoma of the larynx is a rare condition, with less than 40 cases recorded worldwide. CLINICAL RECORD: A 76-year-old man was referred to our clinic with progressive, severe hoarseness and dysphagia. He had been diagnosed with obstructive sleep apnoea by the respiratory physicians and commenced on nocturnal continuous positive airway pressure ventilation. Transnasal laryngoscopy revealed bilaterally enlarged tissue in the region of the arytenoids; biopsies revealed the (previously unreported) diagnosis of bilateral, synchronous rhabdomyoma of the arytenoids...

Rhabdomyoma is an exceedingly rare soft tissue benign tumor of skeletal muscle origin classified into cardiac and extracardiac types based on location. Extracardiac rhabdomyoma is further classified into adult, genital, and fetal type depending on the degree of differentiation. Adult rhabdomyomas are rare, but morphologically characteristic, benign mesenchymal tumors with mature skeletal muscle differentiation that in 90% of cases arise in the head and neck region, mainly in the mucosa of the oropharynx, nasopharynx, and larynx, from the branchial musculature of third and fourth branchial arches...

We describe a case involving a 79-year-old man with symptoms of slowly progressive hoarseness resulting from a rhabdomyoma originating deep to the right true and false vocal folds. We also review the pathology and radiologic findings of rhabdomyoma.

Rhabdomyomas are benign tumors of skeletal muscle derivation. Rhabdomyomas of the head and neck are unusual, and laryngeal rhabdomyomas of the adult type are rare. When they do occur, patients may present with symptoms that have progressed slowly over several years. In extraordinary cases, stridor and airway obstruction manifest. We report a case of adult rhabdomyoma of the larynx that features some of its typical and atypical presenting characteristics. This case also exemplifies the favorable prognosis that results following complete yet conservative surgical excision...

A 4-year-old spayed female Golden Retriever was presented for investigation of progressive loss of bark, continuous panting and increased upper respiratory noise. Examination of the larynx and pharynx under general anaesthesia identified a spherical 5 x 3 cm mass involving the right arytenoid cartilage. Cytological examination of fine needle aspirates from the mass suggested the tumour was a carcinoma, however histological examination in association with immunoperoxidase and histochemical staining identified the mass as a laryngeal rhabdomyoma...

Rhabdomyomas of the larynx are extremely rare benign tumors. Only 25 have been well documented until now. These tumors display a low growing pattern. Diagnosis is based on immunocytochemical studies and electron microscopy. Three histological types are distinguished: adult, fetal and fetal myxoidal or genital. Surgery is the treatment of choice. A new case, adult type, is presented and the literature reviewed.

Extracardiac rhabdomyomas are rare benign tumours showing striated muscle differentiation. Seventy percent of these lesions occur in the head and neck region. The most common sites for these lesions are the larynx, pharynx, and the floor of the mouth. There has been only one previous report of a rhabdomyoma of the oesophagus; two further cases are described.

Rhabdomyomas of the larynx are exceedingly rare. The incidence, sites of occurrence in the larynx, and treatment of these benign striated muscle tumors are reviewed. A case of rhabdomyoma involving the vocalis muscle is presented with magnetic resonance imaging and video-stroboscopic documentation.

A three-year-old male golden retriever had had progressive dyspnoea, exercise intolerance, stridor, and a modified bark for five months. A mass 2 cm in diameter was present dorsal to the right side of the larynx. Histological examination revealed cross-striations in some elongated cells, consistent with a diagnosis of rhabdomyoma, a diagnosis which was confirmed by positive immunohistochemical staining for myoglobin and desmin. The mass could not be removed without total laryngectomy and a permanent tracheostomy and the dog was euthanased...
