Description

Introduction: Middle ear neuroendocrine adenomas are very rare neoplasms, accounting for less than 2% of all middle ear and inner ear tumours. Despite diagnostic imaging being widely available nowadays, diagnosis can be challenging due to non-specific findings and the rare occurrence. The surgeon can still be surprised by the intraoperative findings and the results of histological examinations in the postoperative period. Case presentation: A 48-year-old woman turned to an otorhinolaryngologist with complaints of discomfort and a feeling of fullness in her right ear. Pure tone audiometry and tympanometry were performed, without pathological findings. After one month, the patient undergoes a CT scan of the pyramids. Following the CT scan, the patient repeatedly consults an otorhinolaryngologist, the patient denies new complaints. Surgical therapy is appointed. Right ear surgery was performed - excision of the formation, revision of the tympanic cavity and tympanoplasty. The result of histological examination (haematoxylin-eosin staining method): The morphological and immunohistochemical picture is consistent with an adenoma with neuroendocrine differentiation. MRI examination after surgery and pure tone audiometry and tympanometry were performed. Conclusions: We present the details of a rare case of neuroendocrine adenoma of the middle ear, accounting for less than 2% of all middle ear and inner ear tumours. Middle ear adenoma usually present with nonspecific clinical findings A diagnosis is often delayed due to the rearity of this tumor, and biopsy is usually needed to reach a definite diagnosis. A pathological examination is required to differentiate middle ear neuroendocrine adenoma.Preoperative radiological findings does not always correlate with intraoperative findings and clinical symptoms. Surgical treatment is main therapy, adjuvant radiotherapy and chemotherapy is not recommended. ENT surgeons should keep an open mind and be prepared to change their plan during surgery according to intraoperative findings.. .. .. .
