When a stuffy nose won't go away: Rhabdomyosarcoma masquerading as adenoiditis

Area of Science:

• Pediatric Oncology
• Pathology
• Otolaryngology

Background:

• Embryonal rhabdomyosarcoma is a rare pediatric malignancy originating from immature skeletal muscle.
• It can occur in various head and neck sites, including the nasopharynx, nasal cavity, and middle ear.
• Diagnosis can be challenging due to subtle or absent oropharyngeal abnormalities.

Observation:

• A case of a 7-year-old male with embryonal rhabdomyosarcoma is presented.
• The patient's condition was initially misdiagnosed as adenoiditis by three physicians based on clinical examination and laryngoscopy.
• Symptoms persisted and were refractory to standard treatments for adenoiditis.

Findings:

• This case illustrates that embryonal rhabdomyosarcoma can present with symptoms easily mistaken for common upper respiratory conditions.
• The tumor's ability to mimic adenoiditis highlights diagnostic challenges in pediatric oncology.
• Histopathological confirmation is crucial for accurate diagnosis.

Implications:

• Clinicians should maintain a high index of suspicion for noninfectious etiologies in children with persistent, treatment-refractory symptoms.
• Early and accurate diagnosis of embryonal rhabdomyosarcoma is critical for timely intervention and improved patient outcomes.
• This case underscores the importance of considering rare diagnoses even when common ones seem likely.
