Abstract:
Paragangliomas (PGLs) are rare and encapsulated neuroendocrine tumors (NET), located in the adrenal gland or the extra-adrenal paraganglia. Extra-adrenal PGLs may develop a gangliocytic component with ganglion cells which are called gangliocytic paragangliomas (GPs). The most common location is the duodenum, and they appear with digestive symptoms or as an incidental finding. We described a 43 years old patient, with epigastric pain, nausea and vomiting. The CT-scan reveals a nodular image in the duodenum. An ultrasound-guided FNA was performed and the pathological report revealed neuroendocrine cell groups and neural tissue. Surgery was the chosen treatment. As the patient did not present lymphatic or pancreatic parenchyma invasion, radiotherapy (RT) was not administered. The management of GPs is not well established and multidisciplinary team approach is recommended to lead to therapeutic options. Surgical resection is still key in the treatment, and adjuvant RT may be considered in cases of lymph node invasion.
