BACKGROUND/AIM: Spontaneous regression (SR) of cancer, which indicates the natural disappearance of malignant tumors, is rare. Little is known about the mechanisms underlying SR; however, immunological reactions, infections, injuries, and medications have been presumed. Among previously reported cases of SR, lung cancer cases have been extremely limited.
CASE REPORT: Here, we present a case of lymph node metastasis exacerbation after SR of a primary adenocarcinoma following a biopsy. After complete disappearance of the primary site tumor, metastatic lymph nodes in the mediastinum gradually increased in size as a single lesion. Local treatment with resection and radiotherapy was effective for this metastasis, without recurrence for >3 years.
CONCLUSION: This is an interesting case of SR of pulmonary adenocarcinoma with inconsistent features in the primary and metastatic lesions. When physicians encounter exacerbation of metastatic sites with SR of the primary site in lung cancer, local intervention may be considered as a curative treatment.
