Abstract
[Introduction]
Thymic
carcinoma is a relatively rare disease with a poor prognosis. Although there
are increasing reports of the efficacy of multimodal therapy, no consensus has yet
been reached on therapeutic strategies.
[Case]
A
74-year-old man was referred with valvular heart disease to the internal
medicine department of our hospital. Because chest computed tomography (CT)
revealed a solid tumor with a maximum diameter of 25 mm in the anterior
mediastinum, he was referred to our department. We performed thymectomy under
the suspicion of a thymic epithelial tumor. The pathological diagnosis was squamous
cell thymic carcinoma (pT2N0M0-Stage II). After surgery, although radiotherapy
was considered as adjuvant treatment, the patient was placed on follow-up without
radiotherapy in consideration of comorbidities. A growing pulmonary metastases
in the left lower lobe (S10) occurred two years following the resection of the
tumor; the metastatic nodule was resected. A diagnostic examination detected
squamous cell carcinoma resembling the primary thymic carcinoma. Thus, a
metastatic pulmonary tumor was diagnosed. As the effects of postoperative
adjuvant therapy were unknown at that time, the patient has since been followed
up carefully. Five years and six months have passed since surgery, to date, and
he remains alive without recurrence.
[Conclusion]
We
experienced a case in which long-term survival was achieved by surgical
resection for a solitary pulmonary metastatic recurrence after surgery for
thymic carcinoma. Surgical treatment might resulted in a good prognosis for
patients with a solitary pulmonary metastatic recurrence.
