Diffuse pulmonary infiltration by anaplastic lymphoma kinase negative anaplastic large cell lymphoma: A case report and literature review

Primary gastric anaplastic lymphoma kinase-negative anaplastic large-cell lymphoma

INTRODUCTION Most primary stomach lymphomas are now recognized to originate from B-cell. Primary gastric anaplastic lymphoma kinase (ALK)-negative anaplastic large-cell lymphoma (ALCL) as shown in this case is very rare. CASE REPORT A 59-year-old man presented with a 1-month history of epigastric pain. Computed tomography showed a tumor in the stomach with perigastric lymphadenopathy. Biopsy ...

ALK- negative Anaplastic Large Cell Lymphoma of Bone

Anaplastic lymphoma kinase-positive diffuse large B-cell lymphoma presenting in nasal cavity: a case report and review of literature.

Anaplastic lymphoma kinase (ALK)-positive diffuse large B-cell lymphoma (DLBCL) is a rare subtype of non-Hodgkin's lymphoma (NHL) with distinct morphologic and immunohistochemical features. We reported a 57-year-old female with ALK-positive DLBCL in her left nasal cavity. Histologically, the tumor cells were characterized by plasmablastic morphology and tested positive for ALK in a cytoplasmic ...

ALK-negative anaplastic large cell lymphoma primarily involving the bronchus: a case report and literature review.

Anaplastic large cell lymphoma (ALCL) is a mature T cell lymphoma with characteristic morphologic, immunophenotypic and cytogenetic features. Current WHO classification includes anaplastic lymphoma kinase (ALK)-positive and ALK-negative variants. ALCL rarely presents with obstructive symptoms of the main airway. In addition to reporting a HIV-associated bronchial ALK-negative ALCL in a 44 year-...

A case report of human immunodeficiency virus-associated anaplastic lymphoma kinase protein-negative anaplastic large cell lymphoma

Human immunodeficiency virus (HIV)-associated anaplastic large cell lymphoma (ALCL) is not so common, and anaplastic lymphoma kinase protein (ALK)-negative ALCL is rare and has a low survival rate. We report a case of a 31-year-old Japanese man diagnosed with HIV-associated ALK-negative ALCL who presented with long-lasting fever of unknown origin. The diagnosis was based on a full work-up that ...
