简要病史：	A 33 years old female was diagnosed with Hodgkin lymphoma 3 years ago at an outside hospital, and no outside slides were available for review. Recently she presented with abdominal pain due to umbilical hernia, and image studies revealed a periportal lymph node of 3.9 cm. The lymph node was excised.

组织形态上要考虑富于T细胞的大B细胞性淋巴瘤，只是年龄稍小了些。鉴别诊断主要是结节性淋巴细胞为主型HD。前者缺乏模糊的结节，肿瘤性大细胞散在分布，肿瘤细胞数量较少。

Final diagnosis: T-Cell/Histiocyte-Rich Large B-Cell Lymphoma

http://enjoypath.com/hp/hp-145.htm

T-Cell/Histiocyte-Rich Large B-Cell Lymphoma

CLINICAL FEATURES

A variant of DLBCL with prominent CD8+ T cells and histiocytes
M:F=2:1, 60-70 years of age
Mostly in lymph node, but more frequently presents with high-stage disease (about two thirds in stage III-IV) in bone marrow and spleen, compared with conventional DLBCL

MICROSCOPIC FINDINGS

Diffuse effacement of lymph node with polymorphic cellular population, lack of nodular pattern or sclerosis
Scattered large tumor cells, <10% of the cellular population, dispersed singly, without the formation of discrete aggregates or sheets
Morphology of tumor cells: centroblasts, immunoblasts, pleomorphic, LP (or L&H) cells, or Reed-Sternberg cells
Background: small lymphocytes with mostly CD3+CD8+ T cells; variable numbers of histiocytes; scant plasma cells or eosinophils

再传几张低倍镜图片。

何杰金淋巴瘤的确是重要的鉴别诊断之一。

该病例哪些地方不符合何杰金淋巴瘤？

还有哪些重要的鉴别诊断？

哪些免疫组化染色有助于鉴别诊断？

first background looks like HL,but the especial cell is not enough large

The background of HL usually contains lymphocytes, eosinophils and plasma cells. However, rare eosinophils and plasma cells are present in this cases.

The classic HL cells have abundant cytoplasm with large eosinophilic nucleoli,. The tumor cells in this case show a mixed morphologic features, including centroblastic, immunoblastic, and HL-like.

Hint: what other cells are present in the background in addition to lymphocytes?
