Topical cidofovir can provide effective management of symptomatic oropharyngeal HSV while reducing risk of systemic toxicity and drug interaction and represents an additional approach to management for management in medically compromised patients.

Due to the curative potential and improvement in progression-free survival (PFS), high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is considered the standard of care for several hematologic malignancies, such as multiple myeloma, and lymphomas. ASCT typically involves support with blood product transfusion. Thus, difficulties arise when Jehovah's Witness patients refuse blood transfusions. In order to demonstrate the safety of performing "bloodless" ASCT (BL-ASCT), we performed a retrospective analysis of 66 Jehovah's Witnesses patients who underwent BL-ASCT and 1114 non-Jehovah's Witness patients who underwent transfusion-supported ASCT (TF-ASCT) at Cedars-Sinai Medical Center between January 2000 and September 2018. Survival was compared between the two groups. Transplant-related complications, mortality, engraftment time, length of hospital stay, and number of ICU transfers were characterized for the BL-ASCT group. One year survival was found to be 87.9% for both groups (P = 0.92). In the BL-ASCT group, there was one death prior to the 30 days post transplant due to CNS hemorrhage, and one death prior to 100 days due to sepsis. Based on our data, BL-ASCT can be safely performed with appropriate supportive measures, and we encourage community oncologists to promptly refer JW patients for transplant evaluation when ASCT is indicated.

The good outcome of this case highlights the subtle clinical changes that present early in mucormycosis and the importance of early detection and treatment of post-transplant oral infections by an experienced multidisciplinary team.
