Mycosis Fungoides

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.

Woringer-Kolopp(W-K) disease is a rare, localized, histologically malignant, but clinically indolent lymphoproliferative disorder. It usually shows only a single slowly enlarging skin lesion mainly on the extremities. Some authors have regarded W-K disease as a variant of mycosis fungoides. However, recent studies suggest that W-K disease may represent a spectrum of T cell lymphoproliferative disoreers that may not be related to mycosis fungoides. We report a case of Woringer-Kolopp disease in a 60-year-old male who presented with a solitary slowly growing tumor on his left palm for 3 years. Histopathologic examination showed marked acanthosis and pagetoid infiltration confined to the epidermis. He was treated with 4,000 red electron beam irradiation to the area with complete resolution of the lesion. Three years later, a similar lesion appeared on his left foot dorsum. He was treated as previously with a good response and there has been no new lesion during the last 1 year follow up period.

Woringer-Kolopp disease, also known as localized pagetoid reticulosis, is a rare variant of mycosis fungoides that presents as a solitary localized hyperkeratotic patch or plaque on the extremities and follows a benign course. Effective treatments for Woringer-Kolopp disease include skin-directed therapies such as topical nitrogen mustard, high-potency topical steroids, and phototherapy. Surgical excision has been pursued in cases of small, localized lesions. A 39-year-old man presented with a 3-month history of an asymptomatic plaque on his hand. Physical examination showed a 10-mm-diameter solitary round erythematous hyperkeratotic plaque with a slightly raised edge on the dorsum of his left hand. A skin biopsy revealed that numerous atypical lymphocytes had infiltrated the upper dermis and expanded into the epidermis with a pagetoid pattern. These atypical pagetoid cells were strongly positive for CD3, CD8, and T-cell intracellular antigen-1; focally positive for CD4; and negative for CD20, CD30, and CD56. A subsequent general examination revealed no evidence of systemic involvement and the lesion was treated with surgical excision. Here we report a rare case of Woringer-Kolopp disease.
