Complete resolution of gastric amyloidosis after autologous stem cell transplantation.

A 48-year-old female with multiple myeloma (MM) and amyloidosis presented with massive upper gastrointestinal (GI) bleeding one week after autologous stem cell transplantation (autologous-SCT). Esophagogastroduodenoscopy (EGD) demonstrated necrotic, purple, pigmented, friable lesions throughout the stomach (Figure 1a), along with a bleeding ulcer in the cardia (Figure 1b, Video 1) which was successfully treated with epinephrine (1:10,000) injections. Biopsies demonstrated nodular amyloid deposition (Figures 2) which was Congo red positive. The patient had no further hematemesis and was discharged home 4 days later. Ten months after autologous-SCT, EGD revealed a normal stomach (Figure 3, Video 2) with no histologic evidence of amyloid
