A Rare Case of Primary Pulmonary Anaplastic Large Cell Lymphoma

A Case Report of a Metastatic Primary Gastric Lymphoma; Diffuse Large B-Cell or Burkitt Lymphoma?

Introduction: Primary gastric lymphoma (PGL) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (IHC) and genetic analysis. Case Presentation: A 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise IHC and staging in another center. Inappropriate IHC after surgery showed diffuse large B-cell lymphom...

A case of Primary Bone Anaplastic Large Cell Lymphoma

BACKGROUND Anaplastic large cell lymphoma (ALCL) is a relatively rare subtype of non-Hodgkin's lymphoma (NHL). Like other types of NHL, ALCL primarily involves the nodal area, and sometimes it can involve several extra-nodal sites such as skin, soft tissue, and lungs. However, extensive bone involvement in cases of ALCL is very rare whether it is primary or secondary. Without nodular involvemen...

HISTIOCYTE-RICH B-CELL LYMPHOMA: A CASE REPORT OF A RARE VARIANT OF DIFFUSE LARGE B-CELL LYMPHOMA

The authors describe a case of histiocyte-rich B-cell lymphoma (HR-BCL), a variant of diffuse large B-cell lymphoma, in a 51-year-old man. The patient presented with large axillary lymphadenopathy. Histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic CD20 positive B cells. ...
