Histopathological, immunocytological and ultrastructural observations are reported in the first case of pagetoid reticulosis (Woringer‐Kolopp disease) in Japan. The patient was a 61‐year‐old woman with multiple skin lesions running a chronic and apparently benign clinical course. Histology of the skin biopsies revealed typical pagetoid appearance of the epidermis due to intraepidermal infiltration of abnormal cells. Ultrastructural investigation showed that the intraepidermal abnormal cells were classified into mycosis fungoides cells, Sezary cells, lymphoblast‐like cells, and large blastoid cells and that the mycosis fungoides cells were a major cell population. Inter mediate or transitional cells were found between these cells and large blastoid cells were mostly situated in the basal cell layer. By the rosetting assays of the free cell suspensions prepared from the epidermis of the biopsied skin lesions, 93% of the suspended cells were positive for spontaneous rosette formation with sheep erythrocytes. The immunoperoxidase technique demonstrated no cytoplasmic immunoglobulins in almost all the intraepidermal abnormal cells. These results indicate that the intraepidermal abnormal cells are T‐lymphocytes. Thus, it is concluded that the present case is a cutaneous T‐cell lymphoma of low‐grade malignancy showing prominent epidermotropism. This case is the first description of the disease in Japan.
