Small cell carcinoma is derived from APUDcells of any parts of the body. Usually the cases are discovered in the
lungs and have poor
prognosis.
Small cell carcinoma has been increasingly reported in various organ outside the
lungs, such as the
larynx,
thymus,
esophagus,
stomach,
pancreas,
uterine cervix, and
prostate. Primary
small cell carcinoma of the
stomach is extremly rare. The
histology of the
tumor was
similar to that of ordinary
small cell carcinoma of the
lung, and the
secretory granules were identified by
electron microscopy. We
report a
patient with gastric pure
small cell carcinoma who treated by a radical total
gastrectomy and
chemotherapy.
