Lenalidomide (LEN) is increasingly being used for the treatment of multiple myeloma (MM). Adverse cutaneous reactions to LEN are common and present almost exclusively within one month of initiating therapy. We report a case of delayed-onset LEN-associated eruption presenting over three years after starting treatment. Histopathologic findings are also described, which are infrequently reported for LEN-associated eruptions. Our case serves as a reminder that proper recognition and management of LEN-associated eruption is important in the treatment of MM. Dermatologists should be aware of the potential for delayed presentations of adverse cutaneous reactions to LEN, even years after initiation.

Background: Bone marrow (BM) Measurable Residual Disease (MRD) assessments underestimate disease burden in multiple myeloma, as focal lesions can exist outside the marrow. Functional imaging, like positron emission tomography-computed tomography (PET-CT), offers valuable insights into residual disease beyond the marrow. Combining marrow flow cytometry (FCM) with PET-CT for a composite MRD (cMRD) assessment before and after autologous stem cell transplant (ASCT) is expected to provide prognostic information, particularly in settings where patients receive extended duration of anti-myeloma therapy prior to ASCT.

Multiple myeloma (MM) is an incurable blood cancer characterized by clonal bone marrow plasmacytosis, hypercalcemia, renal failure, anemia, and osteolytic bone disease. Approximately 20% of NDMM patients, not predicted to have high-risk disease at diagnosis, progress early, despite optimal induction +/- ASCT and lenalidomide maintenance, and are subsequently categorized as functional high-risk (FHR) disease. Standardized risk-stratification models incorporate biomarkers of tumor burden, existence of high-risk cytogenetics, with the presence/absence of plasma cell leukemia/extramedullary disease to attribute high-risk at diagnosis; however, depth/duration of response to novel agent-based induction (NA-IND) as dynamic markers of disease risk have not been defined.

Posttransplant lymphoproliferative disorders are a serious complication after solid-organ transplant, with a reported incidence from 2% to 20%. Plasma cell neoplasms in solid-organ transplants represent a rare but increasingly serious complication after solid-organ transplant. We report a case of plasmablastic myeloma, a very rare variant of multiple myeloma with aggressive course and poor prognosis.
