A faecaloma is a mass of faeces most frequently noted in the rectum and sigmoid colon, that is much harder than a faecal impaction due to coprostasis.
Usually, the faecal matter accumulates in the intestine, then stagnates and increases in volume until the intestine becomes deformed and acquires characteristics similar to those of a tumour.
There are several causes of faecaloma and have been described in association with
- Hirschsprung's disease
- psychiatric patients
- Chagas disease
- both inflammatory and neoplastic conditons
- patients suffering with chronic constipation
