Diseased and Normal Lung Photographs, Photos and Xrays

This is a larger squamous cell carcinoma

This is a peripheral adenocarcinoma of the lung.

bronchioloalveolar carcinoma

This is the microscopic appearance of squamous cell carcinoma with nests of polygonal cells with pink cytoplasm and distinct cell borders. The nuclei are hyperchromatic and angular.

This is another sqamous cell carcinoma that extends from hilum to pleura. The black areas represent anthracotic pigment trapped in the tumor.

This is the microscopic pattern of a small cell anaplastic (oat cell) carcinoma in which small dark blue cells with minimal cytoplasm are packed together in sheets.

Multiple variably-sized masses are seen in all lung fields. These tan-white nodules are characteristic for metastatic carcinoma. Metastases to the lungs are more common even than primary lung neoplasms simply because so many other primary tumors can metastasize to the lungs. Even the hilar nodes in this photograph demonstrate nodules of metastatic carcinoma. The nodules are usually in the periphery and do not cause major obstruction.

Here are larger but still variably-sized nodules of metastatic carcinoma in lung.
