“…Only eight of these nodules had a clear diagnosis of PTC on FNA. Surgical pathology provided a diagnosis of infarcted PTC after surgical excision in all 12 cases (21). There are several other reports on infarcted PTC in the literature that suggest these lesions could be a potential cause of true disappearance of tumors (22)(23)(24)(25).…”

“…On average, these changes occur 20 to 42 days after the biopsy (2,3). These changes can also occur spontaneously and are more common in an adenomatous goiter than in a neoplasm (2,4). Literature reports of infarction occurring in papillary thyroid carcinoma (PTC) are rare which has led to the description of "vanishing tumors" (3).…”

Objective: Fine-needle aspiration (FNA) of a thyroid nodule is typically considered a benign procedure. Uncommonly, morphological changes can occur in the nodule or tissue after the procedure. These changes have been noted in tissues like thyroid, breast, lymph node, and prostate. The objective of this case report is to report the rare occurrence of thyroid cancer diagnosed on FNA, appearing as a necrotic mass after near total thyroidectomy and to emphasize the need for confirmation of diagnosis with histopathology. Methods: A 69-year-old man was seen for a self-discovered neck mass. Thyroid ultrasound demonstrated a thyroid nodule with suspicious features. Ultrasound-guided FNA of the nodule was performed with a 22-gauge needle without immediate complications. Results: The cytology was read as consistent with papillary thyroid cancer with a preoperative thyroglobulin level of 15,288 ng/mL (normal range is 1.6–55 ng/mL). After a near total thyroidectomy, histopathology revealed complete infarction of the tumor with no evidence of cancerous tissue remaining. Based on the pathology report, he was considered cured of the cancer and did not receive radioactive iodine therapy. Conclusion: The occurrence of tissue infarction following FNA of a thyroid nodule is rare, reportedly <2%. We conclude a review of the original cytology material and a thorough examination of remaining viable tissue be made. Complete evaluation for invasion of the capsule or surrounding tissue must be ascertained to decrease diagnostic errors.

“…In prostate, the frequency was reported up to 1.3% of all prostatectomies. In thyroid gland, total amount of 92 cases was reported in six series and 11 case reports (summarized in Table ). The frequency varied up to 9.8% in Gordon series .…”

“…Post‐FNA infarction reveals varying degrees of changes with the total replacement of tumor by necrosis without any vital cells at the one end . Vanishing tumor is often used to describe the phenomenon.…”
