Isolated metastasis of lung cancer to the thyroid gland

Collision tumors of the thyroid: A case report and review of the literature

“…Incidence varies depending on source, ranging from 1.25% to 24.2% of autopsy studies . However, clinically relevant incidence lies between 0.05% and 3.1%, which is surprisingly infrequent given the vascularity of thyroid tissue . The most common primaries include the kidneys, breasts and lungs …”

Gastrointestinal metastasis of lung cancer with special emphasis on a long-term survivor after operation

“…There have been many reports showing that long-term survival is possible after resection of both primary lung and metastatic cancers to the brain (Chee et al 2007), adrenal glands (Mercier et al 2005), thyroid gland (Osawa et al 2007), bone (Hirano et al 2005), and liver (Kim et al 2006) if the metastasis is single or confined to a limited area. Our case verified, for the first time, that long-term survival is possible in patients with lung and intestinal metastasis.…”

A Case Report of Thyroid Gland Metastasis in Small Cell Lung Cancer

“…The clinical treatment recommended chemotherapy with cisplatin and etoposide, or chemotherapy and radiotherapy. Osawa et al [4] reported a case of small cell lung cancer underwent chemotherapy consisting of cisplatin and etoposide, followed by prophylactic cranial irradiation. Four years later, a thyroid metastasis was diagnosed then followed by thyroidectomy.…”

“…Of the four types of lung cancer causing thyroid gland metastasis, adenocarcinomas are the commonest followed by squamous and large cell carcinomas. The metastasis of small cell lung cancer to the thyroid gland is rarely reported [4]. The purpose of this report is to present thyroid gland metastasis of a small cell lung cancer, as the first site of metastasis, originally misdiagnosed as thyroid carcinoma, confirmed to be originating from a small cell lung cancer.…”
