Effective treatment of malignant atrophic papulosis (Köhlmeier-Degos disease) with treprostinil--early experience

Orphanet J Rare Dis. 2013 Apr 4;8:52. doi: 10.1186/1750-1172-8-52.


Background: Malignant atrophic papulosis (Köhlmeier-Degos disease; MAP) is an uncommon endotheliopathy with pathological findings similar to the vascular lesions of systemic sclerosis. These two disorders can overlap. When associated with visceral lesions, MAP has been considered almost universally and rapidly fatal. A recent report described dramatic response to treatment with eculizumab, but disease progression after initial response to therapy has occurred.

Methods: We describe the clinical and pathologic findings in two patients, one with MAP and the other with MAP like lesions, who received treatment with subcutaneous treprostinil. One patient had an overlap syndrome with features of systemic lupus erythematosus (SLE) and scleroderma and severe pulmonary hypertension. She also had very extensive MAP like cutaneous lesions. There was no evidence of central nervous system (CNS) disease and laparoscopy revealed no visible MAP lesions on the serosa of the small bowel. The second patient had experienced life-threatening disease progression despite ongoing eculizumab therapy. During this treatment, he had developed CNS and bladder involvement with neurologic symptoms and gross hematuria.

Results: Patient one was placed on therapy with treprostinil for her pulmonary hypertension, but in the months subsequent to initiation of treatment, dramatic and complete resolution of cutaneous MAP like lesions and disabling digital pain occurred. In patient two, therapy with treprostinil was temporally associated with clearing of hematuria, resolution of CNS symptoms and improvement in MRI findings.

Conclusions: Treprostinil may offer a second effective treatment approach to individuals with MAP or "rescue therapy" to those in whom eculizumab treatment has failed to maintain suppression of disease activity.
