ABSTRACT
The incidence of appendiceal metastatic cancer is quite low. In particular, in small cell lung cancer, there is a very low incidence of a metastasis to the appendix. A 75-years old man with right lower quadrant pain, cough and sputum was transferred to our hospital. Abdominal CT revealed acute appendicitis with a perforation. The patient underwent surgery. The frozen sections of the tissue obtained during surgery, indicated a malignancy, but a right hemicolectomy was not performed due to the patient's poor general condition. The histology findings of the appendix were identified as a small cell carcinoma. The abdominal CT scan and chest x-ray at admission day showed a mass in the right lower lobe, and a further evaluation of the lesion was performed including positron emission tomography and flexible bronchoscopy with a biopsy. The pathology findings of the lung mass were also small cell lung cancer. The specimens from both sites stained positive for cytokeratin, cluster designation 56, synaptophysin, chromogranin-A and thyroid transcription factor 1. It was concluded that the appendiceal small cell cancer originated from the lung.
