Neuroblastoma is the most common extracranial neoplasm among paediatric patients, which arises from ectodermal neural crest cells. The most frequent primary site of neuroblastoma arises from retroperitoneum, specifically in the adrenal medulla. We present a rare case of adrenal neuroblastoma metastasis to maxillary sinus in a 20 month-old boy presenting with right maxillary swelling for the past 2 months. Computed tomography (CT) scan of paranasal sinus demonstrated right maxillary mass. A biopsy performed via a sublabial approach, surprisingly revealed neuroblastoma. Subsequent further workup depicted a huge right adrenal tumour. He was diagnosed with adrenal neuroblastoma stage 4 and treated with chemotherapy and surgical resection.
Laryngeal schwannomas are rare lesions that represent less than 1.5% of all benign laryngeal tumors. Its slow and submucosal growth may cause a delay in consultation and management. Herein, a case of right supraglottic schwannoma is diagnosed in a 34-year-old lady who was unconcerned about hoarseness for 10 years. She was referred to otorhinolaryngology clinic for assessment when hoarseness was detected during consultation for a gynecology surgery. Apart from hoarseness, there were no noisy breathing, shortness of breath or aspiration symptoms. Flexible nasopharyngolaryngoscopy showed a submucosal bulge at the right vestibular fold obscuring the vocal fold causing an airway concern. Computer tomography scan of the neck revealed a heterogenous enhancing mass centered at the right supraglottis measuring 2.6 × 2.7 × 2.7 cm. There were no erosions of the adjacent thyroid and arytenoid cartilages. Subsequently, complete excision of the lesion was done endoscopically. Definitive diagnosis of schwannoma was obtained via histopathology examination. This paper presents our approach and operative steps in the excision of this lesion using microlaryngoscopy with cold instruments.
