Hurthle cell carcinoma: a rare variant of thyroid malignancy - a case report.

Oncocytic/Hurthle cell neoplasm is a rare form of thyroid malignancies, derived from follicular epithelium, presenting with a wide variety having either presenting with features of thyrotoxicosis or no any associated symptoms. Case presentation: The authors present a case of a 49-year-old female with a known case of chronic obstructive pulmonary disease and hypertension who presented to our hospital with anterior neck swelling for 4 months that has gradually increased over the time. Physical examination, laboratory test, various radiological imaging, and cytological study led to the diagnosis of Hurthle cell neoplasm. With prompt diagnosis, she was admitted and surgery was done that include right hemithyroidectomy. Though it is a rare type of thyroid malignancy, early diagnosis and proper treatment has shown a very good prognosis. Clinical discussion: Hurthle cell carcinoma initially presents with a single, painless palpable mass in the thyroid with pressure symptoms in advanced cases including dysphagia, dyspnea, and hoarseness. Pain, rapid growth, or significant compressive symptoms are suggestive of an invasive one. Conclusion: This case highlights on rarity of disease, presentation, and availability of treatment modality.
