case_images: Bone marrow biopsy and aspirate revealed a hypercellular marrow almost completely replaced by a diffuse infiltrate of large lymphoid cells (Figures 1(a) and 1(b)) with basophilic cytoplasm, cytoplasmic vacuoles, and large prominent nucleoli (L3/Burkitt lymphoma-like morphology) (Figure 2).
case_images: Aspirate smear, Wright-Giemsa stain, 100x image showing the neoplastic lymphoid cells with basophilic cytoplasm, cytoplasmic vacuoles, and large prominent nucleoli.

case_images: Further characterization of the lymphoid cells using Immunohistochemical stains showed positivity for TdT (Figure 4), CD10, CD20, MUM-1, PAX5, and BCL 2. Interphase FISH analysis for t(9;22) and a MYC gene translocation revealed multiple genetic alterations including: a cell line with a normal chromosome 9 and 22 and concurrent MYC translocation; a cell line with a normal chromosome 9 and 22 and a MYC translocation with an extra copy of MYC translocated to chromosome 7; a cell line with both a t(9;22) and MYC translocation (Figures 4, 5, and 6).
case_images: Interphase FISH analysis showing a normal chromosome 9 and 22, MYC gene translocation, and an extra red MYC signal translocated onto chromosome 7.
