AI Article Synopsis
- The article reviews literature on aerogenous metastasis, which refers to the spread of cancer through the airways, and discusses its mechanisms, imaging characteristics, and importance in clinical settings.
- It highlights that aerogenous spread is often overlooked but is supported by cumulative evidence, suggesting a need for greater awareness.
- Key imaging features can help differentiate aerogenous metastasis from other types of tumor spread and influence staging, treatment decisions, and prognosis for patients with lung cancer.
Article Abstract
Objective: The purposes of this article are to summarize the relevant literature on aerogenous metastasis, explain the putative pathogenetic mechanism of aerogenous spread, present the characteristic imaging and pathologic features, and review the importance of aerogenous spread to staging and clinical management.
Conclusion: Cumulative evidence suggests that aerogenous spread may exist and is underrecognized. Imaging features are helpful in differentiating possible aerogenous spread of tumor from hematogenous and lymphatic metastases and from synchronous primary tumors. The putative occurrence of intrapulmonary aerogenous metastasis of lung cancer has staging, management, and prognostic implications.

Article Synopsis
- - Invasive mucinous adenocarcinoma (IMA) of the lung has unique features such as multicentric lesions and low distant metastasis but a poor prognosis, with median survival under a year.
- - While treatment options are limited, lung transplantation in selected IMA patients has shown improved survival, but with high rates of recurrence often linked to the primary tumor.
- - A notable case of bilateral lung transplantation using cardiopulmonary bypass for stage ⅣA lung-limited IMA achieved 15 months of stable health without disease recurrence or organ rejection, and IMA's characteristics and outcomes are discussed in relation to prior classifications and other lung transplantation cases.
Extended-sleeve resection for endoluminal recurrence of B3 thymoma: does aerogenous spread really exist?

Thymomas are a variant of thymic epithelial tumours. They are considered malignant due to their tendency to local invasion and they showed lower metastatic behaviour. Distal metastasis is rare and an endobronchial mass is a rare presentation.

The clinical significance of lung tumor spread through air spaces (STAS) has been extensively studied, and is recognized as a unique pattern of invasion. Previous studies of STAS have focused primarily on STAS in alveolar spaces, whereas STAS in the bronchiolar spaces (bronchiolar STAS) has been described in only a few case reports only. Here, we examined 306 cases of primary lung adenocarcinoma and found that bronchiolar STAS was present in 18%.

Knowledge about contagiousness is key to accurate management of hospitalized COVID-19 patients. Epidemiological studies suggest that in addition to transmission through droplets, aerogenic SARS-CoV-2 transmission contributes to the spread of infection. However, the presence of virus in exhaled air has not yet been sufficiently demonstrated.

Background: Lepidic adenocarcinoma represents a histologic pattern of non-small cell lung cancer that characteristically arises in the lung periphery with tracking alongside pre-existing alveolar walls. Noninvasive and invasive variants of lepidic adenocarcinoma are dependent on parenchymal destruction, vascular, or pleural invasion. The lepidic-predominant lung malignancies are collectively recognized as slow growing with rare metastasis and excellent prognosis.
