    Abstract:
    BACKGROUND: Autoerythrocyte sensitization syndrome (painful bruising syndrome) is marked by spontaneous and painful ecchymotic bruising, without any biological abnormality, occurring in women with pathological mental profile. Sometimes, when the inflammation is severe, an infectious cellulitis or muscular compression may be suspected. CASE REPORT: A 21-year-old woman was referred for the rapid occurrence of a diffuse and painful inflammation of the right leg, with fever. The leg was red, warm, with diffuse bruising. The foot was fixed in varus equin. The biological parameters were normal. Magnetic resonance imaging showed normal muscles but modifications in the subcutaneous fat, similar to an acute cellulitis. A cutaneous biopsy showed a moderate oedema of the dermis and erythrocyte extravasation. Antibiotics were inefficient on the pain and the aspect of the lesions. Because of the efficacy of saline serum injections on the symptoms and a pathological psychological profile, an autoerythrocyte sensitization syndrome was suspected. The skin test was negative. Psychiatric evaluation revealed a severe personality disorder associated with depression. The ecchymotic lesions disappeared with adapted psychiatric treatment. DISCUSSION: Painful bruising syndrome occurs most often in young women with various psychiatric problems. The lesions are characterized by recurrent, painful, swollen and bleeding bruises in any part of the body. Fever, abdominal pain and external bleeding are possible. Haematological and immunological findings are usually normal. The histology of early lesions reveals oedema of the dermis and modest perivascular infiltrate, whereas extravasated erythrocytes appear later. The magnetic resonance imaging aspect of the lesions has never been described. Abnormalities of the subcutaneous fat are similar to those of acute cellulitis, expressing the inflammation process secondary to the ecchymoses. The syndrome results from complex somatic and psychological mechanisms. Many drugs were tried for the treatment of the disease, without any significant improvement.
