[The ingestion of foreign bodies for the purpose of self-injury. The conservative treatment of 2 clinical cases].

Although not rare, the ingestion of foreign bodies becomes uncommon when it is done with intent to cause self-damage. When used for this purpose, foreign bodies usually take the form of liquid substances, such as caustic agents, detergents, poisons, etc. It is less rare in certain situations like psychiatric and prison settings. The author reports two cases of foreign bodies voluntarily swallowed by patients in prison.
