OBJECTIVE
Pheochromocytoma is a rare catecholamine-producing neuroendocrine tumour originating from the chromaffin cells of the adrenal medulla or extra-adrenal paraganglia. However, there are few bibliometric studies on Pheochromocytoma. Therefore, this study was employed to summarize the global trends and current status in pheochromocytoma by bibliometric analysis.
MATERIALS AND METHODS
The Web of Science (WOS) core collection database was searched for publications relating to pheochromocytoma from 2001 to 2021. Bibliometric analysis was used to examine the data, and Microsoft Excel was utilized to create bar graphs. In addition, VOSviewer was used to carry out co-authorship analysis, co-citation analysis and co-occurrence analysis. CiteSpace was used to analyze the keywords citation bursts.
RESULTS
A total of 8,653 publications published in 1,806 journals by 38,590 authors in 6,117 organizations from 100 countries/regions were included in our study. Among them, USA was the leading countries in terms of total publications and sum of time cited, whereas Eunice Kennedy Shriver Natl Inst Child Hlth & Hum was the leading institutions. The main publications for pheochromocytoma-related articles were . Pacak karel and Eisenhofer Graeme were the main contributing authors. The studies on pheochromocytoma could be grouped into five clusters: Treatment, Mechanism, Etiology, Radiology and Hormones study. Moreover, the radiology study, etiology study and some specific keywords such germlines mutation, mesenchymal stem-cells, autophagy, neuroinflammation, neurotoxicity, and hemodynamic instability, may become the hot spots of future.
CONCLUSION
Although the number of articles on pheochromocytoma has fluctuated slightly over the past 20 years, there has been an overall upward trend. In general, precision medicine research on pheochromocytoma, especially metastatic pheochromocytoma, in terms of diagnosis, treatment, and etiology will be a hot research topic in the future. This study helps to understand the research perspectives, hot spots and trends of pheochromocytoma and provide new insight and a basis for future pheochromocytoma research quickly.

Paragangliomas are mostly benign, slow-growing, hypervascular tumors originating from neural crest derivatives. Head and neck (H&N) paragangliomas represent <1% of all H&N tumors and <5% are malignant. They are mostly non-secreting tumors that originate from autonomous parasympathetic paraganglia. We present a case of right middle ear jugulotympanic paraganglioma, a subtype of H&N paragangliomas, which had been misdiagnosed as otosclerosis for about 10 years. The patient was suffering from worsening tinnitus along with hearing impairment. High clinical suspicion of jugular paraganglioma prevented us from taking a biopsy. Complete surgical excision after preoperative embolization was decided. Embolization resulted in facial nerve paralysis, however, facial nerve rerouting was performed during the complete surgical excision of the tumor. The patient remains disease-free three years postoperatively, with House-Brackmann III facial nerve paralysis.

Paragangliomas are rare, slow-growing, hypervascular, catecholamine-secreting neuroendocrine tumors arising from the paraganglia. Paragangliomas are rarely found in the head and neck and are typically benign, presenting as a painless, slow-growing mass. Surgical extirpation in combination with long-term surveillance has been long regarded as the standard of care; however, the advances in imaging, radiation therapy, and embolization techniques have improved diagnostic and therapeutic modalities. We present a case of an 87-year-old female who had previously undergone resection of a paraganglioma in 1998, with no evidence of disease in 2002. Eighteen years later, the patient presented to the clinic with otogenic complaints. Imaging showed an expansive mass from the jugular foramen with bone destruction and opacification within the ear canal. The patient opted for observation. The patient eventually presented to the emergency room with neurologic manifestations. Imaging showed a cerebellar abscess prompting emergency drainage. Intraoperative cultures grew and , and the patient was started on 6 weeks of IV antibiotic therapy. Debulking of the paraganglioma was performed followed several months by mastoid and ear canal obliteration; however, the patient experienced complications, including dehiscence of the external auditory canal and infection. The patient was eventually treated successfully, marked by a reduction in complaints, a return to baseline activities, and imaging showing no increase in tumor size.

Review
Paragangliomas of the thyroid gland are rare and usually they originate from the inferior laryngeal paraganglia. In this case report, we describe the case of a 78-year-old woman who presented with an incidental finding of thyroid nodule dislocating the trachea. After a systemic and radiological evaluation, right lobo-isthmectomy was performed, and the definitive diagnosis of paraganglioma was reached. Diagnosis of these thyroidal lesions could be difficult due to their rarity, to their specific radiological aspects and the need of employing specific histological staining techniques. Once the definitive diagnosis is reached, patients should undergo a systemic and genetic evaluation. Surgery is the gold standard treatment; radiotherapy should be considered when aggressive behavior is suspected. Regular long-lasting follow-up should be proposed to these patients considering the unpredictable behavior of these lesions.
