[Ekbom syndrome or delusional parasitosis: Three cases in Ouagadougou (Burkina Faso)]

Introduction: Ekbom syndrome is a rare disease characterized by a delusional conviction on the part of the patient of infestation with cutaneous parasites. It is rarely described in an African setting. Herein we report three cases observed in Ouagadougou.

Patients and methods: Case 1: a 40-year-old housewife, living alone since her spouse left her, consulted for a feeling of insects under the skin and exulceration progressing over the previous year. A diagnosis was made of Ekbom syndrome in a depressed patient. Case 2: a 45-year-old bachelor, unemployed and with no children, consulted in dermatology for a sensation of continuous movement of insects under his skin, experienced over the previous six years. This sensation, which was worse in hair-covered areas, led to regular hair removal and untimely cleansing in a bid to dislodge them. Case 3: an 80-year-old patient, widowed for 3 years, consulted for a sensation of insects under her skin over the previous 2 years. This sensation was accompanied by intermittent pruritus and she removed the "insects" from her skin, which she brought to us in a sachet, but which in reality corresponded to debris of dead skin. We concluded on Ekbom syndrome in a depressive patient.

Conclusion: These three cases of delusional parasitism observed in Ouagadougou, Burkina Faso, confirm the main clinical characteristics of Ekbom syndrome and underline the role of emotional and financial isolation, as well as pre-existing psychological difficulties, as potential triggers for this syndrome.
