[Lymphocytoma cutis]

Three patients with skin lymphocytoma and different histologic and clinical appearance of lesions (solitary, grouped, and in the third patient one lesion appeared on the forehead and one on the neck) are presented. By the histologic analysis and the use of immunohistochemical methods the differentiation of these lesions from skin lymphoma and other diseases which could resembe lymphocytoma was made. The method of immunoperoxidase has clearly shown formation of follicules and polyclonal lymphocytes which is the main histologic feature of this pseudolymphoma. By the method of indirect immunofluorescence, antibodies against Borrelia burgorferi were not found in the sera of two patients while in the third it was not performed.
