A 37-lb Tumor

Mayo Clin Proc. n November 2013;88(11):e135 n http://dx.doi.org/ www.mayoclinicproceedings.org n a 2013 Mayo Foundation for M revealed a diffuse, symmetric, painless soft mass in the upper back. Surgical debulking was performed. The specimen removed weighed 37 lb (16.8 kg) (Figures 2 and 3). Histological examination revealed mature adipose tissue. A clinical diagnosis of benign symmetric lipomatosis, or Madelung disease, was made. It is a rare disorder characterized by benign, nonencapsulated fatty masses of the neck, upper trunk, and back. The disease predominantly affects middle-aged men with chronic alcohol abuse. The etiology remains largely unknown, and recurrence is common. The patient was satisfied with the appearance and her ability to walk shortly after the operation.
