Core Tip
Core Tip: Synchronous multiple lung cancer is relatively rare. We report a case of synchronous multiple lung cancers with lymph node metastasis in the hilar region of a small cell carcinoma of unknown origin. Immunohistochemistry was helpful in aiding the diagnosis. As such cases have a poor prognosis, an accurate diagnosis is necessary to determine treatment options.
