case_images: Immunohistochemistry of CD10+ mantle cell lymphoma. Representative lymph node biopsy demonstrates (A) morphologic features of the mantle cell lymphoma (H&E, x1,000) with immunostaining (B) positive for CD5, (C) positive for cyclin D1, (D) Variabily positive for CD10, (E) negative for CD23, (F) Elevated Ki-67 proliferation index (Overall 40%-70%).

case_images: Remarkably, CD10 was found to be variably positive in about 70% of tumor cells (Figure 1).

case_images: Flow cytometric analysis of the bone marrow aspirate confirmed the presence of a monotypic, lambda restricted, CD5+/CD10 dim + B cell population (Figure 2).
