Pazopanib-induced crystal deposition in intestinal mucosa in a patient with retroperitoneal liposarcoma

Int J Urol. 2018 Jun;25(6):627-629. doi: 10.1111/iju.13567. Epub 2018 Apr 12.

Abstract

Pazopanib was administered to a 44-year-old man with local recurrence of retroperitoneal liposarcoma. Computed tomography showed an intestinal edema, which gradually progressed 15 months after pazopanib administration although he had no clinical symptoms. Upper gastrointestinal endoscopy implicated marked edematous hypertrophy of the Kerkling's fold. Pathological findings showed crystal deposition and fat accumulation, without a malignant component. All these abnormal findings resolved after pazopanib discontinuation.

Keywords: intestinal edema; liposarcoma; mucosal crystallization; pazopanib; tyrosine kinase inhibitor.
