A very rare localization of metastatic lung carcinoma to the interosseous membrane.

ABSTRACT

INTRODUCTION: Soft tissue is a rare localization of carcinoma metastasis. Skeletal muscle is considered the most frequent site. The aim of this paper is to report a very rare localization of soft-tissue metastasis of lung adenocarcinoma in the lower leg interosseous membrane, surgically treated at our department. MATERIALS AND METHODS: A 66-year-old man with a history of lung adenocarcinoma was admitted to our department because he complained of a pain resistant to drugs that had persisted for 1 month. Imaging showed that the lesion was unique, localized in the interosseous membrane, with a distal margin more than 2 cm above the ankle platform. A distal fibula resection, including the tumour and a reconstruction according to Capanna type A2 was performed. RESULTS: At the 6 months follow-up, the patient was walking without external support. CONCLUSION: Surgery is not the treatment of choice for soft-tissue metastases, but it may be recommended when the lesion is unique and inducing a pain resistant to anti-inflammatory drugs.
