A 45-year-old female presented to the hematology clinic for evaluation of chronic anemia. She was found to have hemoglobin of 8 g/dL, total leukocyte count of 2.2 × 109/μL, and a platelet count of 123 × 106/μL. Serum protein electrophoresis revealed an M band (3.08 g/dl) which was found to be of IgA-kappa type on immunofixation electrophoresis. X-ray skull showed lytic lesions, and the serum calcium, urea, and creatinine levels were 7.2 mg/dl, 41 mg/dl, and 0.58 mg/dl, respectively. Bone marrow aspirate identified 82% cells with histiocytoid appearance having central to peripherally placed round tiny nucleus and abundant foamy, crumpled papery cytoplasm [Figure 1]a. Bone marrow trephine biopsy was replaced with sheets of histiocytoid cells having pseudo-Gaucher cell-like appearance [Figure 1]b. Immunohistochemistry for CD138 and CD68 was performed, which highlighted a strong membranous positivity for CD138 in all of these cells [Figure 1]c and [Figure 1]d.

(b) Bone marrow trephine biopsy showing large histiocytoid cells with abundant eosinophilic cytoplasm (H and E, ×200). (c) Immunohistochemistry for CD138 showing strong membranous positivity in these cells (immunoperoxidase stain, ×200). (d) Immunohistochemistry showing absence of CD68 expression in these cells (immunoperoxidase stain, ×200)|

Pseudo-Gaucher cell-like plasma cells are rarely reported and are potential mimickers of storage disorder. Pseudo-Gaucher cells can be seen in various disorders such as Hodgkin's lymphoma, thalassemia, and chronic myeloid leukemia including multiple myeloma; however, plasma cells itself showing the pseudo-Gaucher cell type morphology is an intriguing phenomenon.,
