Healing of chronic necrobiosis lipoidica lesions in a type 1 diabetic patient after pancreas-kidney transplantation: a case report.

Abstract

Necrobiosis lipoidica (NL) is a degenerative disease of dermal connective tissue of unknown etiology characterized by erythematous plaques preferentially localized to distal extremities. Skin lesions show a chronic relapsing nature. NL is often associated with diabetes mellitus and satisfactory treatment options are lacking. We describe the spontaneous healing of NL lesions after pancreas and kidney transplantation in a Type 1 diabetic patient with chronic NL recalcitrant to a variety of standard treatments. The 31-yr-old male patient had experienced NL lesions for more than 15 yr; despite various systemic and topical treatments, the skin lesions had pregressively enlarged. Because of end-stage renal disease, a simultaneous pancreas and kidney transplantation was performed and immunosuppressive therapy with tacrolimus (TAC), mycophenolate mofetil (MMF), and prednisone was started. Pancreatic transplantation maintained satisfactory metabolic control with no need of exogenous insulin. After transplantation, skin lesions slowly healed without any specific treatment, leaving residual areas of fibrotic scars. A skin biopsy confirmed the absence of typical NL lymphocytic and histiocytic inflammatory response. Clinical remission of NL lesions may probably be explained by the concomitant effect of multiple-drug regimen for immunosuppression (TAC, MMF, and prednisone) and improved skin microcirculation secondary to the good metabolic control provided by pancreas transplantation.
