Primary pulmonary lymphoma (PCL) is rare and represents only 0.5-1% of the malignant lung tumour. Pulmonary MALT most common histological aspect. The pathophysiological mechanism remains poorly known, unlike other locations lymphoma, no pathogen has so far been associated with localization disease. It characterized by slow evolution atypical clinical presentation which delays diagnosis. form «...

Primary pulmonary NK/T cell lymphoma is extremely rare. The authors reported a case of primary pulmonary NK/T cell lymphoma in a 47-year-old man presented with fever, cough, and chest pain. Morphologically, an angiocentric/angiodestructive growth pattern with coagulative necrosis was observed. On immunohistochemical staining, the atypical lymphocytes showed TIA-1+, CD56+, Ki-67 40%+, Cytokerati...

The primary pulmonary diffuse large B-cell lymphoma (PPDLBCL), a kind of non-Hodgkin's lymphomas, itself is a rare entity. Its association with primary B-cell gastric lymphoma has not been established yet. Herein we present a case of PPDLBCL along with a literature review. This case is special and extremely rare as it has concurrent primary gastric B-cell lymphoma.

Extranodal involvement is common in lymphomas associated with human immunodeficiency virus infection (HIV) and acquired immunodeficiency syndrome (AIDS). However, primary pulmonary AIDS-related non-Hodgkin’s lymphoma is very rare and only few reports were published in the medical literature. Clinical presentation is nonspecific, with “B” and respiratory symptoms. Also, patients were with advanc...

Non-Hodgkin lymphoma usually arises from lymphoid or nodal tissue, and can occasionally involve other sites. Extra-nodal marginal-zone B-cell lymphoma of mucosaassociated lymphoid tissue (MALT lymphoma) is uncommon and constitutes around 8% of all non-Hodgkin lymphomas. Most MALT lymphomas are of gastric origin and lung involvement is rare. Primary pulmonary lymphoma is defined as clonal lympho...

Primary lymphoma of the lung is rare and is usually of B cell type. Tissue samplings taken by transbronchial biopsy and computed tomographic (CT) guided needle biopsy of the right perihilar area of an elderly woman who presented with refractory pneumonia showed T cell lymphocytosis with no evidence of active infection. The patient’s respiratory status rapidly deteriorated and she eventually die...

Primary cutaneous CD30+ T cell lymphoma is rare lymphoma originally in and confined to the skin. These lymphomas usually present as a large solitary and often ulcerated nodule. Its prognosis is a good and has a good response to radiotherapy. We report a 34- year- old man who had primary cutaneous CD30+T cell lymphoma on his face, which presented as an ulcerated nodule.
