Madelung's disease in a non-alcoholic Ethiopian male patient mistaken for obesity: a case report.

BACKGROUND

Madelung's disease (MD) is a rare disorder of fat storage characterized by the presence of diffuse, symmetrical deposition of subcutaneous fat around the neck, shoulder, arm, trunk and thigh. Although its cause is not fully understood, this benign condition is commonly presented among adult males with Mediterranean origin and history of alcohol abuse. Patients often presents with compression of vital structures, cosmetic disfigurement and associated psychosocial problems and systemic comorbidities. It is often under-recognized by physicians, possibly due to obliviousness of the condition and often misdiagnosed as obesity.

CASE PRESENTATION

We present a 65-year-old non-alcoholic black Ethiopian man, presented with a slowly growing body fat in his trunk and proximal limbs associated by multiple joint and back pain which got worse recently. He denied any history of chronic alcohol use. On examination, huge, bilateral, non-tender, soft, globular masses in his torso, shoulder, arm and thigh with bilateral breast enlargement. On investigation his biochemical profile was normal except hyperuricemia (10.6 mg/dl). Imaging of the cervical and lumbar vertebrae showed excess subcutaneous fat depositions with degenerative disc disease. Biopsy from the mass revealed non-encapsulated lipoma and he was diagnosed with type II MD. We treated his pain with supportive therapy and discharged in stable condition. The patient deferred surgical treatment.

CONCLUSIONS

Madelung's disease is often reported among white adult males with chronic alcoholism. However, our case reported a black man without the typical risk factor which was misdiagnosed as obesity. Hence, clinicians should be aware of MD and need to consider it in their differential diagnosis when encountered with a patient having progressive centripetal fat deposition with or without a history of alcoholism and systemic comorbidities. As early detection of this disorder helps to avoid diagnostic delays and prevent complications through timely interventions which will in turn improves patient quality of life.
