A Case of Woringer-Kolopp Disease on the Leg / 대한피부과학회지

ABSTRACT

Woringer-Kolopp disease is a rare variant of mycosis fungoides and it is also known as localized pagetoid reticulosis. It presents as a solitary, localized hyperkeratotic patch or plaque on the extremities with a slowly progressive course. A 51-year-old female presented with a 6-year history of a well-defined erythematous plaque with an indurate border on the left leg. The lesion was asymptomatic and it had gradually enlarged. A skin biopsy showed hyperkeratosis and acanthotic epidermis with an infiltration of atypical pagetoid cells, and these cells were revealed to be the cytotoxic T cell phenotype on immunohistochemical staining. We report here on a case of Woringer-Kolopp disease along with a review of the relevant literature.
