Histopathology: Histopathology has diagnostic value. It can be seen that the dermal and subcutaneous tissues are dilated and filled with large tumor cells. It can be seen that the extravascular tumor cells are focally clustered.

Immunohistochemistry: Tumor cells express CD19, CD20, CD22, CD79a and monomorphic surface immunoglobulins, and immunoglobulin gene clone rearrangements can be found.

Diagnosis and identification of intravascular large B cell lymphoma

According to the clinical manifestations, the characteristics of skin lesions, histopathological features, immunohistochemical examination, can be diagnosed.
