Branchial Cleft

We report a rare case of papillary thyroid carcinoma incidentally found within a branchial cleft cyst. Only four other cases have been described in the literature. A total thyroidectomy and selective neck dissection was performed, and no evidence of occult primary disease was found after review of fine sections. Branchial cleft cysts are the most common lateral neck masses. Ectopic thyroid tissue within a branchial cleft cyst is an unusual phenomenon, and papillary thyroid carcinoma arising from this tissue is extremely rare. Clinicians are left with a diagnostic dilemma when presented with thyroid tissue neoplasm within a neck cyst in the absence of a thyroid primary—is this a case of metastatic disease with a missed primary or rather carcinoma arising in ectopic thyroid tissue? A thorough discussion of the etiologies of these lateral neck masses is reviewed including the embryogenesis of thyroid tissue in a branchial cleft cyst. The prognosis of patients with papillary thyroid carcinoma in lateral neck cysts without a primary site identified appears to be good following excision of the cyst and total thyroidectomy. Other management recommendations regarding these unique lateral neck malignancies are also presented.

Histopathological Results

Papillary thyroid carcinoma is the most common thyroid malignancy and frequently metastasizes to regional lymph nodes. Occasionally, metastatic lymph nodes are palpable without the evidence of primary tumour. Papillary thyroid carcinoma of lateral neck cyst is a rare condition. It may arise from thyroid primary which underwent cystic degeneration or true malignant transformation of ectopic thyroid tissue. Herein, we reported two cases with preoperative diagnosis of benign lateral neck cyst but postoperative histopathological results showed primary papillary thyroid carcinoma. Ultrasonography and computed tomography of the neck in both cases showed no significant thyroid lesion. However, the patient in Case  2 was subjected for total thyroidectomy and histopathological results showed the origin of primary tumour. In conclusion, thorough investigations including total thyroidectomy are indicated in cases of papillary thyroid carcinoma of lateral neck cyst. This practice is to ensure that this type of thyroid cancer can be detected earlier because it has a very good prognosis if treated earlier.

Papillary Thyroid

Papillary thyroid carcinoma frequently metastasizes to regional lymph nodes. However, cervical lymph node metastasis as a sole manifestation of occult papillary thyroid carcinoma is rarely observed. Ectopic thyroid is an uncommon condition defined as the presence of thyroid tissue at a site other than pretracheal area. Approximately 1–3% of all ectopic thyroid tissue is located in the lateral neck. This entity may represent the only functional thyroid tissue in the body. Malignant transformation of ectopic thyroid is uncommon; but even rarer is the development of papillary carcinoma on it. We present a case of a 33-year-old man with an incidental lateral neck mass diagnosed after a motor vehicle accident. Total thyroidectomy and lymph node resection were completed without evidence of papillary thyroid carcinoma. Malignant transformation of heterotopic thyroid tissue was the final diagnosis. The possibility of an ectopic thyroid cancer should be considered in the differential diagnosis of a pathological mass in the neck. The uniqueness of this case strives in the rarity that the thyroid gland was free of malignancy, despite ectopic tissue being positive for thyroid carcinoma. Management strategies, including performance of total thyroidectomy, neck dissection, and treatment with radioiodine, should be based on individualized risk assessment.

Ectopic thyroid tissue is ubiquitous in the body, most frequently seen at the base of tongue, accounting for approximately 95% of reported cases. Branchial cleft cyst, a congenital abnormality, can occasionally harbor thyroid tissue inside the cyst. These ectopic thyroid tissues can develop the same disease as the orthodox thyroid gland, including the malignant diseases. Papillary thyroid carcinoma arising in the branchial cleft cyst was extremely rare, total of only 14 cases were reported in the literature. Herein, I report additional case which was discovered incidentally after surgery.

AbstractObjective:To review the diagnosis of primary papillary carcinoma of ectopic thyroid tissue within branchial cleft cysts, and to discuss the diagnostic challenge of differentiating this condition from metastatic disease when an occult microcarcinoma is found in the thyroid gland.Methods:These comprise a case report and a literature review. We present the case of a 75-year-old woman with papillary thyroid carcinoma within the wall of a recurrent, 15 cm, lateral neck cyst.Results:Histological examination of the patient's thyroid gland found a 0.5 mm papillary thyroid microcarcinoma.Conclusion:Our differential diagnosis was primary papillary carcinoma arising from ectopic thyroid tissue, or metastatic cystic degeneration of a lateral lymph node. We make an argument for the former.

Large cystic mass is an unusual presentation of papillary thyroid carcinoma, accounting for less than 10% of cases. To make a diagnosis of papillary thyroid carcinoma is challenging since the tumour can mimic a benign lateral neck mass. Therefore, a systematical approach to a patient with neck lump is required so that accurate diagnosis and appropriate treatment can be made. We present a case of a 25-year-old female presenting with an asymptomatic left neck cystic mass diagnosed as a metastatic lymph node of papillary thyroid carcinoma only after surgery.
