“…Most general accounts of intestinal neoplasia stress the variability of the morphological characteristics of these lesions and the signs they produce, and among anecdotally reported cases, such variation is emphasized by the wide spectrum of clinical presentation. Histories range from a few days to several months and signs from acute peritonitis due to perforation (Eckerlin, 1974;Zontine. Meirhenry & Hicks, 1977;Laratta el al., 1983) through weight loss and vomiting caused by gradually developing bowel obstruction (Biery & Berg, 1966;Case et al, 1968;Howard et al, 1973;Boothe et al, 1977;Feeny, Clausner & Johnston, 1982) to those of acute or chronic intestinal haemorrhage (Geib & Abrevaya, 1965: McCurnin, Blevins & Pearson, 1969Kolaja & Fairchild, 1973;Giles, Hildebrandt & Montgomery, 1974) and even apparently benign abdominal distension (Watson, 1970).…”
