Self-cannibalism (autosarcophagy) in psychosis: a case report.

Only nine previous cases of self- or auto-cannibalism (autosarcophagy) have previously been reported in the literature. Here, we report a 29-year-old man with psychosis and a history of polysubstance use who presented after his second attempt to self-cannibalize. This case raises questions about the underlying causes and dynamics of self-cannibalism in psychiatric illness and its relation to other types of self-harm behavior.
