Woringer-Kolopp disease is a localized epidermotropic T cell lymphoma with
good prognosis. We describe a 79-year-old man with an erythematous scaly pl
aque of the foot. Clinical diagnosis of psoriasis, parapsoriasis and fungal
infection were proposed Histopathological and immunohistochemical findings
were characteristic of Woringer-Kolopp disease. We observed an immunohisto
chemical positivity of tumour cells for the anti-CD103 antibody (alpha E be
ta 7 integrin) according to the epidermotropism of this localized cutaneous
T cell lymphoma.
