DefinitionThis section has been translated automatically.

Group of very rare, large cell lymphomas of the skin that are not localized to the legs (other) and are therefore not included in the significantly more common large cell cutaneous B-cell lymphomas of the leg (see below Primary cutaneous diffuse large B-cell lymphoma leg type). They are addressed as a separate entity. This group also includes morphologic variants of diffuse large B-cell lymphoma, such as anaplastic or immunoplastic subtypes and T-cell-rich or histiocyte-rich large B-cell lymphomas. See"Diffuse large B-cell lymphoma" (Internal Medicine).

ManifestationThis section has been translated automatically.

More likely to occur in older people.

Clinical featuresThis section has been translated automatically.

Red, brownish-red or blue-red, smooth knots or plaques.

HistologyThis section has been translated automatically.

Diffuse infiltrates in the area of the entire dermis and the upper subcutis. The epidermis remains predominantly free of infiltrates. The histopathological pattern shows predominantly large cells with the characteristics of centrocytes and centroblasts. Numerous mitoses.

Differential diagnosisThis section has been translated automatically.

Clinical differential diagnoses: S. and lymphoma, cutaneous B-cell lymphoma.

TherapyThis section has been translated automatically.

Primarily radiotherapy, if necessary excision (in case of solitary occurrence).

Alternative: Interferon alfa (low dose) or monoclonal anti-CD20 AK ( Rituximab).

Alternative: polychemotherapy (e.g. CHOP regimen).

In nodal large B-cell lymphomas, combination therapy of CHOP and rituximab proved superior to CHOP therapy alone in terms of remissions and overall survival in large numbers of cases.

Progression/forecastThis section has been translated automatically.

These lymphomas seem to have a rather good prognosis.
