Abstract
BACKGROUND: Paraneoplastic pemphigus (PNP) occurs more often in patients with hematologic malignancies (HMs) than in patients with solid cancer. Lung bronchiolitis obliterans (BO) is a severe complication of PNP. OBJECTIVE: To determine the precise clinical and biologic features of HM-associated PNP and identify factors associated with mortality and survival. METHODS: Systematic review of previously described cases of PNP associated with HMs. RESULTS: A total of 144 patients were included. The HMs were non-Hodgkin lymphoma (52.78%), chronic lymphocytic leukemia (22.92%), Castleman disease (18.60%), and other underlying hematologic malignancy (5.70%). The mortality rate was 57%, and most deaths occurred within the first year after the diagnosis of PNP. Multivariate analysis showed that (1) the presence of antienvoplakin antibodies and BO were significantly associated with death, and (2) a toxic epidermal necrolysis-like clinical pattern, bullous pemphigoid-like clinical pattern, and BO were significantly associated with decreased survival. LIMITATION: Only case reports with sufficient mortality data were included. CONCLUSION: PNP associated with HM has a high mortality rate. The toxic epidermal necrolysis-like and BO-associated forms are independent survival factors in PNP associated with HMs.
