Thyroid Metastasis from Gastric Carcinoma: Report of a Case

Abstract

Thyroid metastasis from gastric carcinoma is rare. In this report, we describe the case of a patient in whom a rapidly growing thyroid metastasis was found 3 months after an operation for gastric carcinoma.

Metastatic signet ring cell carcinoma presenting as a thyroid nodule: Report of a case with fine‐needle aspiration cytology

“…14,15 In our case, the histological evidence of vascular invasion in the primary tumor suggests hematogenous dissemination of the tumor. Poorly differentiated adenocarcinoma is the most common thyroid metastasis from the stomach.…”

“…14,15 If the thyroid metastasis is the only malignant disease remaining, adequate surgical resection of the metastatic tumor may be a life-saving procedure. However, there is no consensus regarding the role of surgery for management of metastatic cancers to thyroid.…”

“…4,6,10,13 Although metastases from gastrointestinal tract malignancies are unusual, the majority of them are from either esophageal or colonic primary. 10,14,15 Although the morphological features of most metastatic carcinomas are distinct and can be separated from primary thyroid lesions on fine-needle aspiration (FNA) cytology, 3,4,6,7,16,17 there are occasions in which a metastatic neoplasm presents a diagnostic dilemma, particularly when it shares cytomorphological features with primary thyroid lesions. [18][19][20][21][22] It is critical to differentiate a metastatic tumor from primary thyroid lesions, as the clinical management is quite different between the two entities.…”

Metastasis of distal esophageal carcinoma to the thyroid with presentation simulating primary thyroid carcinoma: a case report and review of the literature

“…ITM originating from the gastro-esophagus is poorly documented. A review of the English-language literature, searching for patients with secondary cancerous growth in the thyroid formed by transmission of tumor cells from primary esophageal and gastric carcinoma disclosed a total of four [9-12] and five reported cases [7,13-16], respectively. This article presents an additional case of thyroid metastasis from esophageal carcinoma occurring in a Chinese man and reviews the related references.…”

Pancreatic metastasis from gastric carcinoma: a case report

“…The most frequent sites of tumor recurrences include local, regional and peripheral lymph nodes, as well as the liver, the lungs, and the peritoneum [5]. Furthermore, solitary metastasis in other organs, such as the thyroid gland or the spleen have been described [6,7]. In contrast to direct infiltration into the pancreas, metastases of gastric cancer into the pancreas are considered to be extremely rare and to our knowledge only four cases have been reported in the English literature [8-10].…”
