Neutrophil-Rich Anaplastic Large Cell Lymphoma of T-Cell Lineage

Extreme neutrophil granulocytosis in a patient with anaplastic large cell lymphoma of T-cell lineage.

We describe a 47-year-old male admitted with fever and extreme neutrophil granulocytosis (up to 80 x 10(9)/L). All microbiology tests and test for autoimmune disease were negative. CT scan showed pulmonary infiltrates bilaterally, mediastinal lymphadenopathy and splenomegaly. Conventional pathological examination of bone marrow and lymph node biopsies did not demonstrate malignant cells and inf...

ALK- negative Anaplastic Large Cell Lymphoma of Bone

Anaplastic Large Cell Lymphoma Associated With Breast Implants

A forty two years old woman with a history of bilateral breast augmentation for cosmetic reasons was presented for poor healing of the surgical site. Tissue and periprosthetic fluid were removed from the wound site revealing an atypical lymphoid infiltrate. Subsequently the patient developed axillary lymph adenopathy. Excisional biopsy was performed. Flow cytometry was non-diagnostic. She conti...

Collision Anaplastic Large Cell Lymphoma (T-Cell/Histiocyte-Rich) and Diffuse Large B Cell Lymphoma: A Pathologic and Clinical Evaluation

A collision tumor of T and B-cell lymphomas occur rarely. In this article we report a collision tumor of anaplastic large cell lymphoma and diffuse large B cell lymphoma in a 46 years old female. The tumor showed predominantly neoplasmtic anaplastic large cell lymphoma (ALCL) component expressing CD30 and ALK with smaller areas of CD20+ diffuse large B cell lymphoma component. Polymerase chain ...

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. ...
