Background: Dermatitis artefacta (DA) is a self-inflicted dermatologic injury sometimes produced for secondary gains. Laboratory investigations, including histologic examination of lesional tissue biopsy, are usually negative and do not give a clue to the correct diagnosis. Patients and Methods: Over a five-year period, 14 patients were diagnosed with DA at King Fahad Hospital (KFH) in Al Baha during routine outpatient and inpatient dermatologic consultations. The diagnoses were based on vagueness of history given by the patients, and the presence of bizarre skin lesions distributed over sites accessible to the patients' hands. Investigations excluded the possibility of other diseases. In some cases, consultant psychiatric assessment was sought in order to identify possible underlying psychopathologic factors. Seven patients were hospitalized while the rest were managed as outpatients. Results: The 14 patients comprised 12 females and two males aged 12 to 71 (mean 25.9) years. All except one were Saudis. DA in the males was probably caused for secondary gains. The females, four of whom were married and eight single, were aged 12-36 (mean 21.8) years. Nine of the females (64%) had identifiable severe emotional or psychiatric problems. The remaining two were unmarried and had no identifiable underlying factors. Conclusion: This study reveals that the presentation of DA in Saudi Arabia is essentially similar to what has been reported from other parts of the world. It brings into focus a medical problem which needs to be recognized, as greater awareness may bring about earlier correct diagnosis and treatment.

Psoriasis vulgaris is an uncommon skin disease among Nigerians. There were only 44 cases out of a total of about 5,250 skin patients (0.8%) seen during the 7-year period from 1977 to 1984 at the consultant skin clinic, Ahmadu Bello University Teaching Hospital, Kaduna, Nigeria. Males were predominant. The age range was 1 1/2 months to 65 years, with a mean age of 29.8 years. The peak incidence was in the 21-30-year group. Clinical features were the same as in Europeans, but morbidity was very low. Arthropathy and nail involvement were rare, comprising only 4.5 and 15.9% of cases, respectively.
