Chest wall seeding of nocardiosis as a complication of a percutaneous transthoracic needle biopsy

This paper highlights an uncommon complication of a percutaneous transthoracic needle biopsy (PTNB). A patient with rheumatoid arthritis who was on immune suppressive drugs underwent a PTNB of a lung nodule. The histology showed “organizing usual interstitial pneumonia-like changes.” Unfortunately, one month after the PTNB, she developed a large deep-seated chest wall abscess at the biopsy needle tract and the previously seen lung nodule was larger. Nocardiosis sp. was isolated from the chest wall abscess. The lung and chest wall lesions were resolved with Bactrium and Fluconazole. The final diagnosis was pulmonary nocardiasis complicated by chest wall seeding following the PTNB procedure.

A Case Report of Myxoma in the Lung / 결핵

Since Virchow first introduced the term myxoma to describe a tumor that recapitulates the structure of the umbilical cord, it has been increasingly recognized that many diverse neoplasms may acquire a similar myxoid appearance. Myxoma have evolved within the pathology literature from tumors often described in practically all sites to the currently recognized subtypes restricted to the heart, skin, soft tissue, and bone. Pulmonary myxoma is extraordinary rare. We experienced pulmonary myxoma in a 63 year old man. The pulmonary radiology showed mass in right upper lung field, and percutaneous transthoracic needle lung biopsy was performed to confirm the myxoma.
