ABSTRACT

Background: Thyroid cancer is the most common cervical neoplasm, these tend to have a nodular and solid appearance on imaging; however, cystic components may occur in 2.5%-6%. Among the most frequent causes of cystic lesions are the anomalies of the branchial arches and thyroglossal cyst; however, these lesions can occur in the context of well-differentiated thyroid cancer. It is important to know the differential diagnoses in these atypical presentations for a correct approach and treatment.
Clinical case: A 40-year-old male patient with a growing mass in the right neck for 6 months. On physical exam a 7 x 7 cm tumor was palpated with regular and smooth edges, mobile. Imaging studies revealed a right thyroid nodule and a hypodense mass with well-defined and regular borders, antero-medial to the sternocleidomastoid muscle. A total thyroidectomy with central lymph node dissection and resection of the right cervical cyst was performed. The histopathological results showed a papillary thyroid carcinoma and a thyroglossal cyst.
Conclusions: The correct diagnosis of cystic masses of the neck is important due to its different implications in the therapeutic approach. Although these usually have a benign behavior, we always have to take into account the possibility of a metastasis or a relationship with some malignant component.
