[A resected case of metastatic lung cancer after curative operation in appendiceal cancer]

A rare intense of a metastatic lung cancer after an operation for a primary appendiceal cancer is reported. A 51-year-old woman was admitted to Yamato Municipal Hospital due to a right lower abdominal pain. Subsequently, a curative right hemicolectomy was performed for a primary appendiceal cancer. Two and a half years later, a chest X-ray and a CT scan revealed a solitary coin lesion in the right lower lung, and she was readmitted to our hospital where a percutaneous needle aspiration of a portion of this lesion was carried out. A cytological examination of this specimen led to a diagnosis of a mucinous adenocarcinoma, with a suspected appendiceal cancer metastasis. Thus, a wedge resection of the right lower lobe was performed. A year and a half later, the patient is still alive and shows no signs of a recurrence. In addition to discussing this case, autopsied cases of appendiceal cancer in literature are also reviewed.
