Subcutaneous seeding of hepatoid thymic carcinoma after percutaneous needle aspiration biopsy

Abstract

Percutaneous needle aspiration biopsy is a reliable and useful procedure for diagnosing tumor with a low rate of complications and high diagnostic reliability. Subcutaneous malignant seeding of the needle tract is a well-known complication of percutaneous needle aspiration biopsy. Implantation metastases of the abdominal and chest walls have been reported after puncturing the tumor lesions of the liver, kidney, adrenal gland, lung and pleura. We report here on a case of subcutaneous seeding of hepatoid thymic carcinoma on the right upper back after a percutaneous needle aspiration biopsy.
