Necrotising fasciitis after bortezomib and dexamethasone-containing regimen in an elderly patient of Waldenström macroglobulinaemia.
Bortezomib and high-dose dexamethasone-containing regimens are considered to be generally tolerable with few severe bacterial infections in patients with B-cell malignancies. However, information is limited concerning the safety of the regimen in elderly patients. We report a case of a 76-year-old man with Waldenström macroglobulinaemia who suffered necrotising fasciitis without neutropenia after the combination treatment with bortezomib, high-dose dexamethasone and rituximab. Despite immediate intravenous antimicrobial therapy, he succumbed 23 h after the onset. Physicians should recognise the possibility of fatal bacterial infections related to bortezomib plus high-dose dexamethasone in elderly patients, and we believe this case warrants further investigation.
