diffuse large b cell lymphoma is the most common type of non-hodgkin's lymphoma, representing nearly one-third of all cases. any organ can be involved, making a diagnostic biopsy imperative. when the lungs are the involved organs, it is called primary pulmonary lymphoma (ppl). hereby, we present a case of primary pulmonary lymphoma (ppl) that demonstrated a single large mass on chest ct and had...

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.

Primary cutaneous large B-cell lymphoma leg type is a rare andaggressive neoplasm as defined by the recently updated WorldHealth Organization - European Organization for Research andTreatment of Cancer. We report a case of an 80-year-old manwith multiple cutaneous lesions. Here, we review the availableliterature and summarize clinical features and management ofthis type of cutaneous B-cell lymp...

primary cutaneous anaplastic large cell lymphoma is a t-cell malignancy with atypical cd30 positive lymphocytes. pseudoepitheliomatous hyperplasia is an uncommon finding in primary cutaneous anaplastic large cell lymphoma, and may mimic squamous cell carcinoma as pseudomalignancy. careful attention of a pathologist to correct diagnosis of pseudoepitheliomatous hyperplasia and its underlying cau...

Abstract B-cell lymphoblastic lymphoma (B-LBL) is an uncommon subtype of pediatric non-Hodgkin Lymphoma (NHL) which rarely involves the skin primarily. The positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-D: -glucose integrated with computed tomography (18F-FDG PET/CT) scan findings of a 8-year-old boy with cutaneous B-LBL were presented. PET/CT scan demonstrated mild FDG up...

Rituximab is a chimeric mouse-human antibody that targets the CD20 antigen, which is found in both normal and neoplastic B cells. In recent years, it has been increasingly used to treat cutaneous B-cell lymphoma and is now considered an alternative to classic treatment (radiotherapy and surgery) of 2 types of indolent lymphoma, namely, primary cutaneous follicle center lymphoma and primary cuta...

BACKGROUND Several epidemiological studies have suggested an association between cutaneous melanoma and non-Hodgkin's lymphoma. METHODS We pooled the data from seven cohort studies and calculated the risk of secondary occurrence of cutaneous melanoma after non-Hodgkin's lymphoma, and of non-Hodgkin's lymphoma subsequent to the occurrence of cutaneous melanoma. RESULTS There were 137 612 pat...

b-cell lymphoblastic lymphoma (b-lbl) is an uncommon subtype of pediatric non-hodgkin lymphoma (nhl) which rarely involves the skin primarily. the positron emission tomography with 2-deoxy-2-[fluorine- 18] fluoro-d: -glucose integrated with computed tomography (18f-fdg pet/ct) scan findings of a 8-year-old boy with cutaneous b-lbl were presented. pet/ct scan demonstrated mild fdg uptake in the ...

Primary cutaneous gamma-delta T-cell lymphoma is a rare subtype of primary cutaneous peripheral T-cell lymphoma. In the latest World Health Organization / European Organisation for Research and Treatment of Cancer classification and World Health Organization classification (4th edition, 2008), the entity previously called “subcutaneous panniculitis-like T-cell lymphoma with gamma-delta T-cell p...
