Leukemia is the most common childhood malignancy and often presents with nonspecific symptoms. Occasionally, it presents with extramedullary manifestations, which have been more frequent in cases of myeloid lineage or T cells. However, precursor B-cell leukemia/lymphoblastic lymphoma can also have extramedullary manifestations in some patients. Describing certain clinical features along with diagnostic imaging can establish a presentation pattern and suggest a diagnosis in the pediatric population. Herein, we present a series of four patients with extramedullary manifestations of B-cell lymphoblastic leukemia, describing their clinical imaging and histopathological characteristics.

Central nervous system (CNS) involvement in Waldenström macroglobulinemia (WM) is a rare complication that can manifest as Bing-Neel syndrome (BNS) or as histological transformation (HT) to diffuse large B-cell lymphoma (DLBCL). We report data from a single-center cohort of 469 patients consecutively diagnosed with WM between 2000 and 2022. BNS was identified in 1.

Acute myeloid leukemia (AML) can be presented with extramedullary manifestations, more frequently involving skin and rarely other sites, such as the urinary tract. We report the case of a 37-year-old male patient with a history of testicular cancer who presented to the emergency department with cytopenias and hematuria. Bone marrow analysis diagnosed AML (French-American-British(FAB) classificationM4 subtype, karyotype showing inv16).

Despite the success of the CD19xCD3 T cell engager blinatumomab in B-cell acute lymphoblastic leukemia (B-ALL), treatment failure is common and can manifest with antigen loss and extramedullary disease (EMD) relapse. To understand the impact of leukemia genetics on outcomes, we reviewed 267 adult patients with B-ALL treated with blinatumomab and used next generation sequencing to identify molecular alterations. Patients received blinatumomab for relapsed/refractory (R/R) disease (n=150), minimal residual disease (MRD+) (n=88), upfront as induction (n=10), or as consolidation in MRD- state (n=19).

Background: Intradural extramedullary tuberculoma of the spinal cord (IETSC) is an exceedingly rare manifestation of tuberculosis (TB) affecting the central nervous system.
Case Description: A 33-year-old immunocompetent female with disseminated TB, including pulmonary involvement and leptomeningeal tuberculomas, developed progressive paraplegia and urinary incontinence over 2 months. Magnetic resonance imaging revealed diffuse intradural extramedullary soft tissue from C7 to L2 vertebral levels, indicative of abscess formation and severe spinal cord compression.

Cutaneous manifestations of multiple myeloma are rare but, as with other extramedullary manifestations, carry a worse prognosis. We present the case of a 65-year-old man with immunoglobulin G κ multiple myeloma and prior autologous stem cell transplant. On subsequent therapy, he presented with multiple new cutaneous and subcutaneous left hip masses.
