Schwannoma is a benign solitary neoplasm emerging from the Schwann cells of the peripheral, cranial and autonomic nerves. Approximately 25 to 45% of schwannomas occur in the head and neck region. However, schwannoma in the subfrontal area, nasal cavity or paranasal sinus is very rare and accounts for only 4% of these neoplasms. We experienced a case of schwannoma in the subfrontal area and left nasal cavity in a 74-year-old man who complained of recurrent rhinorrhea. We report this unusual case of schwannoma with a review of the literature.
Woakes' syndrome is a group of disease which include recurrent nasal polyps resulting in the broadening of the nasal pyramid, the onset of hypoplasia of frontal sinus and bronchiectasis, as well as the production of mucous discharge. Children and young adults are mostly susceptible to Woakes' syndrome due to the plasticity of the bone. Even though the exact etiology is unknown, genetic factor is thought to be influential because it is often diagnosed in siblings. Otolaryngologically, the mainstream method of removing nasal polyp by endoscopic sinus surgery as well as topical or systemic treatment can be helpful. We report two siblings who visited our clinic both complaining of nasal obstruction. The patients presented with recurrent nasal polyps and showed signs of bronchiectasis, which led to the diagnosis of Woakes' syndrome. These rare cases are presented here with a review of related literature.
Oncycytoma is a tumor which is abundunt with granular and eosinophilic cytoplasm and mitochondria. It can be found in various organs such as the kidney, thyroid gland, pancreas, and breast. Salivary gland is reported to be involved with oncocytoma in less than 1% among the salivary gland tumors. A 65-year-old female visited presenting with recurrent lump of the left parotid gland. She had been diagnosed with oncocytoma after left superficial parotidectomy 8 years ago. Physical examination revealed multiple painless tumors in the left parotid gland. Ultrasound and computed tomography showed multiple mass in the left parotid gland. The patient had a revision parotidectomy. Pathology confirmed an oncocytoma and nodular oncocytic hyperplasia. We report a rare case of recurrent oncocytoma and nodular oncocytic hyperplasia from the parotid gland and report the case with related literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
