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 T-cell lymphomas (CTCLs) encompass a clinically and biologically heterogeneous group of non-Hodgkin lymphomas (NHLs) defined by clonal proliferation of skin-homing malignant T lymphocytes and natural killer cells. They account for up to 75% to 80% of all cutaneous lymphomas. The current WHO-EORTC classification of cutaneous lymphomas with primary cutaneous manifestations lists...

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+ lymphoproliferative disorders (LPDs), including lymphomatoid papulosis (LyP), anaplastic and nonanaplastic CD30+ large-cell lymphoma, and borderline cases, comprise a clinical and histologic spectrum. Primary cutaneous and primary nodal CD30+ anaplastic large-cell lymphomas (ALCLs) are distinct clinical entities that have identical morphologic features but differ in age ...

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...

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...
