Thyroglossal duct cyst: A cytopathologic study of 26 cases

Thyroglossal duct cyst (TDC), or embryologic remnants of thyroid gland, is a common congenital anomaly. TDC may cause a midline neck mass, which occasionally may become infected, and rarely gives rise to carcinoma. As a number of other nonneoplastic and neoplastic lesions can cause cystic masses in the neck, we explored the role of fine-needle aspiration (FNA) in making a preoperative diagnosis of TDC for a more accurate and timely clinical intervention. Twenty-six cases of TDC were identified from the cytopathology files of The Johns Hopkins Hospital in a 15-yr period (1990-2004). Material was obtained by FNA with or without radiologic (ultrasound) guidance. Smears were air-dried and stained with Diff-Quik, or wet-fixed and stained with Papanicolaou stain. Cytomorphologic characteristics were serially analyzed. Follow-up (tissue resection [n = 9] and clinical charts [n = 17]) was reviewed in all cases. Patients ranged in age from 8 to 83 yr (mean age, 55) with M:F ratio of 1.4:1. The size of the cyst ranged from 1.2 to 5 cm (mean 2.5 cm), as evaluated on radiological scans. The most common clinical presentation was a non-tender, mobile neck mass, which was painful on swallowing. Follow-up confirmed TDC in 18/26 cases (69%), whereas 8/26 cases resulted in various other benign lesions. During the same time period, 11/18 (61%) cases of surgically resected TDC were missed on prior FNA. Therefore, FNA showed a diagnostic sensitivity of 62% and a positive predictive value (PPV) of 69% for the diagnosis of TDC. The cytomorphologic features of TDC included the following: colloid (thick and fragmented, thin and watery, or mucinous), macrophages, lymphocytes, or predominantly neutrophils. The epithelium was ciliated columnar, metaplastic squamous or of mature squamous type. Thyroid epithelium was only rarely present (11%). FNA is only moderately sensitive for a preoperative evaluation of TDC. Cytomorphologic features are not unique; however, in the right clinicoradiologic setting should lead to an accurate diagnosis. Abundant colloid, most often with ciliated columnar epithelium, is the predominant cytopathologic finding. Thyroid epithelium is rarely identified. Differential diagnosis involves branchial cleft cyst, lymphoepithelial cyst, thyroid gland lesions, and lymphadenopathy (of various etiologies).

“…10 Intraoperatively, projection of cyst going under the body of hyoid bone made us to realise that it is thyroglossal cyst. [11][12][13] Shahin et al showed that FNAC has a sensitivity of 62% and a positive predictive value of 69%. So, it can be helpful in establishing the diagnosis of a thyroglossal cyst in the correct clinical scenario.…”

BACKGROUNDThyroglossal cysts are the most common cause of congenital cyst formation in the neck that may present at any age. Classically, it presents as an anterior midline neck swelling that moves with deglutition and protrusion of the tongue. Occasionally, thyroglossal cyst present clinically in atypical manner, which may pose a diagnostic challenge. MATERIALS AND METHODSPatients came to outpatient department with anterior neck swellings of the neck during the period from June 2014 till May 2015 were included in this study. Swellings of the thyroid gland are excluded. RESULTSA total of 10 patients were included in the study. All patients were found to be adults in our study out of them 8 were males (80%) and 2 were females (20%). The site of the cyst was infrahyoid in 9 cases and 1 case showed suprahyoid (Figure 6). Clinically, 8 cases (80%) showed classical midline cystic presentation and in two cases (20%) the cysts were presented in lateral neck up to the level of sternocleidomastoid muscle and movement with deglutition and protrusion of tongue was not appreciated. In these two cases, fine needle aspiration and ultrasound were inconclusive. In all patients, Sistrunk's operation was performed. Histopathological report in these two cases reported as thyroglossal cyst.

“…Finally, several authors have described thyroglossal ducts cysts lateral to the midline. [8][9][10] Clearly, when a narrow-field approach is used, as described in the classic Sistrunk procedure, some ductal material may be left behind. Further, any operation that depends on the surgeon correctly following a tract and separating normal from abnormal tissue has the potential for error, especially in an inflamed or scarred neck.…”

OBJECTIVE: The recurrence rate of thyroglossal duct cysts removed by the classic Sistrunk procedure exceeds 4%, even in skilled hands. Simple reexcision fails in 33% of these patients. Recent pathology literature suggests that the tracts of thyroglossal duct cysts may arborize, arguing for a wide-field approach to recurrent lesions. We describe the anatomic rationale and technique of an en bloc central neck dissection in children, on the basis of cadaver dissections and histopathologic review of recurrent thyroglossal duct cyst specimens. METHODS: We reviewed the medical records of all the children undergoing surgery for thyroglossal duct cysts and fistulas during the years 1990 to 1998 by the senior author. En bloc central neck dissections were performed on several cadaver specimens to further delineate the anatomic rationale for this procedure. RESULTS: We have performed an en bloc central neck dissection in 7 children, 5 with recurrent or multiply recurrent thyroglossal duct cysts. None has had a recurrence after follow-up of 9 months to 6 years. All have acceptable functional and cosmetic results. CONCLUSION: An en bloc central neck dissection is a logical and effective surgical technique for the removal of recurrent or multiply recurrent thyroglossal duct cysts.
