Abstract: INTRODUCTION: Thyroglossal cyst is a commonly encountered clinical entity resulting due to persistence of Thyroglossal duct and transformation of few embryonic cells into a cyst. It is more common in the supra-hyoid portion of the midline of the neck. The incidence of malignant change in the Thyroglossal cyst is reported as between 1 to 1.8 percent. Papillary carcinoma is common and seen in nearly 80 percent of the cases of the Thyroglossal cysts. Surgical excision with Sistrunk operation is the standard treatment of choice followed by subtotal or total thyroidectomy whenever indicated. Case presentation: A female patient aged 31 years presented with swelling in supra-Hyoid region of the neck. FNAC confirmed Thyroglossal cyst; Histopathology showed de novo papillary carcinoma of thyroid. DISCUSSION: windstorm criteria were used to confirm the diagnosis. Post-operative care was taken to exclude primary in the Thyroid gland. CONCLUSIOINS: Primary Malignancy in the Thyroglossal cyst is a rare entity. It is presented here for its presentation as there was no other malignant focus in the Thyroid gland. Thorough work up is necessary to rule out occult primary.
