Hong, Park, and Shin: A Case of Partial Spontaneous Regression of Non-Small Cell Lung Cancer


Spontaneous regression is extremely rare in lung cancer and this in spite of its global high incidence. So far, less than 30 such cases have been reported in the literature. We report here on the case of a 68-year-old man who had the diagnosis of adenocarcinoma and in absence of any medical therapy, he had a partial spontaneous regression of tumor.

Figures and Tables

Figure 1
Chest X-ray and CT scan on admission showed a large lobulated mass suggestive of a radiologic diagnosis of primary lung cancer.
Figure 2
The cytologic diagnosis of adenocarcinoma was established by percutaneous needle aspiration (A, Papanicolaou stain, ×100; B, H&E stain, ×400).
Figure 3
The chest X-ray and CT scan after 22 months show a marked decrease in the size of the pulmonary mass.
