Background: Post-treatment I-131 whole body scan (WBS) is known to be a very sensitive test in detecting metastasis in differentiated thyroid cancer (DTC). Therefore, in the presence of this sensitive method, the role of chest radiography (CXR) in the diagnosis of pulmonary metastasis has been questioned. Objective: The present study aimed to find the prevalence of pulmonary metastasis found on...

Metastatic tumors to the heart unlike primary cardiac tumors are not rare. Despite its frequency, cardiac metastasis is commonly detected only during autopsy as the symptoms of disseminated metastasis prevail over symptoms caused by cardiac metastasis and hence is overlooked most of the time. Tumors more commonly found metastasizing to the heart are malignancies of lung, breast, esophagus, lymp...

Renal cell carcinoma (RCC) accounts for only 3% of adult malignancies, and the lung is the most common site of metastasis of this tumor, which may be accompanied by pleural metastasis. However, solitary pleural involvement is very rare and its presentation with dyspnea as the first manifestation of RCC is extremely rare.We describe a 39-year-old male with episodes of dyspnea dating back 6...

Uterine leiomyosarcoma (ULC) is an uncommon neoplasm characterized by poor prognosis, it can predispose to distant metastasis, causing various symptomatic presentations. We present a unique case of large heterogeneous mass in the lung cavity arising from ULC, with complete absence pulmonary symptoms and concurrent coronavirus disease 2019 (COVID-19) infection. A high degree clinical suspicion r...

Purpose Giant cell tumor of bone (GCTB) is an intermittent tumor with a low probability of pulmonary metastasis. Our aim was to investigate the risk factors and establish a nomogram predictive model for GCTB pulmonary metastasis. Methods We retrospectively evaluated GCTB patients at our center from 1991 to 2014. The cohort was randomized into training and validation sets. Univariate and multi...

Pulmonary metastasis from carcinoma of the papilla of Vater is considered to be a late event, and patients can be treated with radiotherapy, chemotherapy, or palliative surgery. However, surgical treatment of an isolated lung metastasis has not been reported. We present a surgical case of solitary pulmonary metastasis from carcinoma of the papilla of Vater. A 51-year-old man underwent pylorus-p...

A 67-year-old male was admitted to our hospital because of pulmonary metastasis from colo-rectal cancer. Chest computed tomography revealed three tumor shadows just under the pleura. Because the tumors were adjacent to each other, we performed an en bloc pulmonary resection. Pathologically, two of the tumors were diagnosed as pulmonary metastases; the remaining tumor, however, was diagnosed as ...

It is well known that more than 50% of the patients with osteosarcoma affected pulmonary metastasis at the time of diagnosis of the primary lesion although such a dormant micrometastasis is often asymptomatic and clinically undetectable until relapse. There are several clinical evidences showing that some of these patients relapse of pulmonary metastasis within months after the removal of the p...

BACKGROUND Pulmonary metastasis from prostate cancer is considered to be a late event, and patients can be treated with chemotherapy or hormonal manipulation. However, there has been only a few reports on surgical resection for pulmonary metastasis from prostate cancer. CASE PRESENTATION We present a surgical case of solitary pulmonary metastasis from prostate cancer. A 73-year-old man underw...

metastasis from a malignant tumor to the palatine tonsils is rare, accounting for only 0.8% of all tonsillar tumors, with only 100 cases reported in the english-language literature. various malignant lung carcinomas may metastasize to the tonsils. a few cases of tonsillar metastasis from neuroendocrine lung carcinoma have been reported. a 67-year-old female underwent a right tonsillectomy becau...
