What condition is characterized by painful lipomas on the torso and proximal extremities?

Adiposis dolorosa, also known as Dercum’s disease, is characterized by the development of painful lipomas, particularly on the torso and proximal extremities. Patients with this condition experience significant discomfort from these fatty tumors, which can impact their quality of life. The lipomas associated with adiposis dolorosa are distinct in that they not only present visually but also have a palpable tenderness, which is a hallmark of this condition. The pain associated with these lipomas can be chronic and debilitating, making the diagnosis of adiposis dolorosa relevant to understanding its impact on patients' health and well-being.

In contrast, multiple lipomatosis typically refers to a genetic condition of simply having multiple lipomas that are usually not painful. Familial chylomicronemia is a lipid metabolism disorder characterized by high levels of chylomicrons in the blood, leading to symptoms like pancreatitis, but it does not specifically involve painful lipomas. Lipodystrophy involves the abnormal distribution of body fat and typically leading to metabolic derangements, but again, does not emphasize painful lipomas as a primary symptom. Thus, adiposis dolorosa is the specific condition that encompasses the characteristics outlined in the question.
