Lipodystrophy in Patients with Acromegaly Receiving Pegvisomant

Abstract

We report seven patients with acromegaly who developed lipohypertrophy at the pegvisomant injection site. Pegvisomant was discontinued due to dissatisfaction with lipohypertrophy by four patients. Lipohypertrophy regressed in all patients when the medication was discontinued. Lipohypertrophy recurred when two patients were rechallenged with pegvisomant. Patients receiving pegvisomant should undergo frequent examination of injection sites for lipohypertrophy.
