Abstract Paragangliomas are neuroendocrine tumour originating from the neural crest-derived paraganglia with majority arising from the head and neck. (1)Thyroid paraganglioma are exceedingly rare neuroendocrine tumours accounting for <0.1% of thyroid malignancy (1) We present a 57 years old gentleman who was referred to ENT surgeon following discovery of a two month history of lump on his left neckIt has not changed in size and not caused any symptoms such as anxiety, sweats, palpitations, dizziness or unexplained headaches. He has a Past medical history of epilepsy following a Road traffic accident 28 years ago leaving him seizure prone. He has no family history of neuroendocrine tumours His ultrasound scan of his thyroid gland showed a 25 x 23 x 15mm lesion lying anteriorly within the left thyroid lobe. There are two highly reflective foci which could represent microcalcification. It was classified as U5 lesion He proceeded with fine needle aspiration which confirmed carcinoma of the left thyroid gland with no clear differentiation between follicular or papillary carcinoma. He undergone a total thyroidectomy and left central level VI lymph node dissection His histology confirmed a thyroid paraganglioma staining strongly positive for neuroendocrine markers (Synaptophysin and chromogranin) while S-100 shows positivity in the sustentacular cells. He was referred for genetic testing which demonstrate no evidence of mutation in FH, SDHAF2, SDHB/C/D, RET, MAX, TMEM127 and VHL gene. He was commenced on levothyroxine replacement at a dose of 150micrograms OD. His urine metanephrines is 178.1pmol/L (0-510), urine normetanephrines 192.9pmol/L (0-1180) and 3-methoxytyramine <75pmol/ L (0-180) (all normal). His MRI neck revealed no synchronous tumour. He continues to be followed up under our endocrine clinic. Conclusion: Due to the rarity of these tumours, their natural history is mostly unknown. Nevertheless, postoperative surveillance should include plasma or urinary metanephrines and ultrasonography. References: 1 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3824793/

Needle Aspiration Cytology

Background: Fine needle aspiration cytology is a minimally invasive technique used in the initial diagnosis of different types of lesions located in head and neck region commonly originating from cervical lymph node, thyroid gland, salivary glands and soft tissues. The objective of this study was to evaluate the diagnostic accuracy, sensitivity and speci city of FNAC in various head and neck lesions in correlation with their histopathological examination. Materials and methods: A hospital based prospective study was conducted among 209 patients with palpable head and neck region swellings in the Department of Pathology, Bhaktapur Cancer Hospital and the Department of Pathology, Nepal Medical College from August 2014 to July 2015. FNAC were done from palpable masses of head and neck regions. Data entry and analysis were done using SPSS 17. Result: There were 209 FNAC cases enrolled, out of which lymph node lesions (n=128) were the most common lesions followed by thyroid (n=40), other soft tissues (n=27) and salivary gland (n=14). Reactive lymph nodes, colloid goiter, epidermoid cyst and sialadenosis were the predominant diagnosis of lymph nodes, thyroid gland, soft tissues and salivary gland respectively. Highest accuracy, sensitivity and speci city were observed in thyroid gland, salivary gland and soft tissues. However, four false negative results for malignancy were reported in lymph node lesions. Conclusion: Head and neck region swellings are the commonly encountered conditions. FNAC being highly accurate, sensitive and speci c makes it useful and reliable procedure for screening and diagnosis of palpable masses in head and neck region.

Medical literature about the role of endoscopic ultrasound (EUS) in identifying thyroid lesions is limited. We present a case of secondary thyroid cancer from renal cell carcinoma (RCC) metastasis, diagnosed by thyroid EUS-fine needle aspiration (FNA) approach that was done for staging of esophageal adenocarcinoma, in a patient with 11-year history of complete right nephrectomy for RCC. An 81-year-old female patient underwent EUS for the evaluation of a newly discovered distal esophageal cancer. A hypoechoic, round, and well-demarcated mass that measured 26.9 mm × 21.9 mm was noticed in the right lobe thyroid gland. Therefore FNA was performed. The cytological results were consistent with metastatic RCC. In conclusion, EUS-FNA of thyroid nodule is a feasible and safe technique that can be used to evaluate any suspicious thyroid nodule. This case emphasizes the importance of carefully examining the thyroid gland during routine upper esophageal EUS examinations in the presence of history of nonthyroidal cancer.

Leiomyosarcoma (LMS) of the trachea is an extremely rare malignancy with only a few reported cases in English literature. As such the diagnosis can be frequently missed or delayed. We present a case of a 69-year-old male who underwent tracheostomy for airway obstruction secondary to glottic squamous cell carcinoma and treated definitely with radiation therapy. Subsequently, the patient developed LMS of the tracheostomy site. The case further details multiple risk factors that could contribute to development of LMS including radiation exposure, prior malignancy, and chronic inflammation. These risk factors have been well established for LMS in other sites but less so in the head and neck region, which is the subject of our discussion. We also review the current guidelines for head and neck as well as limb sarcomas and discussed role of surgery or radiation and their accompanying challenges in management of this rare malignancy.

History Of

Pancreatic heterotopia (PH) is a common, but typically small (<1 cm), incidental and asymptomatic finding; however, PH should be considered even for large and symptomatic upper gastrointestinal masses. A 27-year-old white woman presented with a 3-week history of burning epigastric pain, nausea, early satiety, and constipation. Physical examination revealed epigastric and right upper quadrant tenderness with normal laboratory workup, but imaging revealed a 5-cm, partly cystic mass arising from the gastric antrum with resulting pyloric stenosis and partial gastric outlet obstruction. Endoscopic ultrasound-guided fine needle aspiration revealed PH – an anomalous pancreatic tissue lying in a nonphysiological site. The patient ultimately underwent a resection and recovered uneventfully, with a complete pathologic examination revealing normal exocrine pancreatic tissue (PH type 2) without malignant transformation. We report a case of heterotopic pancreas manifesting as severe gastric outlet obstruction, in addition to a thorough diagnostic workup and surgical follow-up, in a young adult. Differential diagnoses and features that speak to benignity of a large, symptomatic mass lesion (PH in particular) are discussed.

AbstractIn 2021, the German Society of Otorhinolaryngology, Head and Neck Surgery is celebrating the 100th anniversary of its foundation. The aim of this article is to present the main inventions and progress made in Germany before 1921, the date the society was founded. Three chronological periods are discernible: the history of otorhinolaryngology (ORL) in Germany until the beginning of the 19th century, focusing mainly on the development of scattered knowledge; the birth of the sub-specialties otology, laryngology (pharyngo-laryngology and endoscopy), and rhinology in the 19th century, combining advances in knowledge and implementation of academic structures; and the creation of the ORL specialty at the turn of the 20th century, mainly concentrating on academic organization and expansion. This period was crucial and allowed for the foundation of the German Society of Otorhinolaryngology, Head and Neck Surgery on solid ground. Germany played an important role in the development and progress of ORL internationally in the 19th century with such great contributors as Anton von Tröltsch, Hermann Schwartze, Otto Körner, Rudolf Voltolini, and Gustav Killian to mention a few.
