Though the, primary carcinoma of the vermiform appendix is rare, the secondary
carcinoma of the vermiform appendix is extremely rare. About fourty cases have been
reported through the world. The breast is most common primary site, and
adenocarcinoma is most common form. The metastatic carcinoma of the vermiform
appendix, from squamous cell carcinoma of the uterine cervix, were extremely rare.
The authors experienced a case of metastatic squamous cell carcinoma of the
vermiform appendix, in thirty-two years old housewife. She was diagnosed with
carcinoma of the uterine cervix on December, 1983, and treated with a radical
hysterectomy on February, 1984, at Chicago, and with a radiation therapy. She had been
suffered from palpable masses on left axilla and left neck region, and coughing and
chest pain. After an excision biopsy, on Augusta, 1984, she showed intestinal obstruction
sign including abdominal distension with abdominal pain. A right-sided hemicolectomy
was performed on November, 1984. During gross examination, the wall of the distal
portion of the vermiform appendix was moderately thickened, and showed homogeneous
light yellow cut surface. On microscopic examination, there were clusters of tumors that
had negative staining properties in argentaffin and argyrophil stained preparations. On
electron microscopic examination, the secretory granules were not found, and the
characteristics of squamous cells, including intercellular spaces, desmosomes and
tonofibrils, were noted.
