T-cell pseudolymphoma cd30 positive L98.8

Group of reactive T-lymphocytic tissue reactions that cannot be assigned to a distinct clinical picture. In this respect, this histological terminology is not easily transferred to clinical nomenclature. The causes are often infectious triggers such as insect bite reactions, scabies granuloma, herpes infections; furthermore, these tissue reactions are also detected in pseudolymphoma-like drug reactions.

Mostly dense lymphoid cell infiltrate penetrating the dermis, which may also be wedge-shaped; interspersed with esoinophilic granulocytes. In addition, large activated CD30+ lymphocytes, occurring individually or in groups. The histological picture corresponds to lymphomatoid papulosis, which must be clinically defined.
