Children with liver disease rarely have large numbers of spider naevi. Although the finding of five or more spider naevi is more common in liver disease, many normal children also have one or more of these lesions.

Biopsy of an endoscopically normal large bowel, and of the normal terminal ileum in isolation, yields little abnormal histology. Diarrhoea per se does not identify patients at higher risk of abnormal histology. Increased age, however, does, and mucosal biopsy in the endoscopically normal colon and rectum may be more cost-effective in patients aged more than 60 years.

AimsThis case series intends to expand currently limited knowledge regarding the existence and diagnostic significance of intramucosal fat in colorectal polyps.MethodsClinicopathological features of nine such polyps were reported following histopathological review, including S100 and EMA immunohistochemistry.Results and conclusionsSuch review subdivided seven polyps into three groups: (1) mucosal perineurioma/serrated polyps with fat among the perineurial stroma (three cases); (2) submucosal lipomas with adipose tissue extending into the overlying mucosa (two cases) and (3) polyps with intramucosal adipose tissue only, that is, the newly described but less-recognised entity known as intramucosal lipoma (two cases). The two remaining polyps of this series did not include submucosa but, from assessing their muscularis mucosae, were favoured to represent intramucosal lipomas. The first two phenomena are formally described for the first time by this case series. The last of these three diagnoses should prompt investigations for Cowden syndrome, but intramucosal lipomas are more often sporadic/non-syndromic.
