Acute intermittent [corrected] porphyria. An often forgotten diagnosis in acute abdomen.

Three cases of Acute Intermittent Porphyria (AIP) are described. All presented with acute intermittent abdominal pains. One had grand-mal epilepsy as well. Two were diagnosed by chance. In the third case the diagnosis was thought of. It is suggested that AIP should always be considered as one of the differential diagnosis in Acute Abdomen in West Africa.
