Woringer-Kolopp disease (pagetoid reticulosis)

Clinicopathologic features and treatment outcomes in Woringer-Kolopp disease

“…Immunophenotype analysis may demonstrate either CD3 1 /CD4 1 or CD3 1 /CD8 1 cells, with variable positivity for CD30. 4,5,7,13,14 Alaibac and Chu 15 previously suggested that a third CD4 e and CD8 e phenotype may consist of gamma-delta T cells, but this immunophenotype is now considered primary cutaneous gamma-delta T-cell lymphoma under the WHO-EORTC classification, and is associated with a more aggressive clinical presentation. 1 Currently, Woringer-Kolopp disease is synonymous with pagetoid reticulosis, and is classified as a variant of mycosis fungoides in the WHO-EORTC classification system for cutaneous lymphomas.…”

Mycosis Fungoides Palmaris et Plantaris

“…All patients had stage la disease at diagnosis. After the diagnosis of MFPP was made, the disease remained confined to the initial area of involvement in 15 (94%) of 16 patients, but extensive plaques subsequently developed on the trunk and lower extremities in one patient.13 No patient experienced extracutaneous involvement during the follow-up interval. Two patients (our patient 2 and the patient described by Stasko et al12) revealed a few (<5%) Sézary cells in the pe¬ ripheral blood, but low numbers of Sézary cells may be identified in inflammatory dermatoses and do not estab¬ lish a diagnosis of Sézary syndrome.26 Therapies used for MFPP are presented in the Table. In summary, MFPP is an expression of MF that pre¬ dominantly affects, and often initially presents, on the palms and soles and clinically mimics many common pal¬ moplantar dermatoses.…”

Non-melanocytic mimics of melanoma: Part I: intraepidermal mimics

“…The cells arrange in single units or nests, which are mainly seen in the lower layers of the epidermis. The dermis demonstrates an infiltrate composed predominantly of mature and reactive lymphocytes, histiocytes, and sometimes few plasma cells 22 – 24. MF has similar histological features to PR (fig 7A,B).…”
