A 50-year-old woman presented to her dermatologist in 1999 with a 6-month history of recurrent pruritic scaly plaques on the abdomen, arms and hairline. The rash, which was presumed to be seborrhoeic dermatitis, improved after treatment with systemic prednisolone. No skin biopsies were taken at the time.
In 2004, she developed a leonine facies (Box, A), widespread erythroderma, alopecia, generalised peripheral lymphadenopathy, hyperkeratosis of the palms, and bilateral swollen pinnae with otorrhoea (Box, B).

a name="0_pgfId-1097912">A: Leonine facies. B: Oedematous right pinna. C: Left pinna after radiotherapy.
Punch biopsies revealed Pautrier microabscesses containing atypical CD4+ lymphocytes. A peripheral blood film showed Sézary cells, confirming Sézary syndrome.
The patient’s condition deteriorated despite treatment with methotrexate, prednisone, bexarotene, interferon, psoralen and ultraviolet A, as well as extracorporeal photopheresis.
Radical palliative radiotherapy to the head and neck improved her leonine facies and otitis externa (Box, C).
The patient died in 2006, 8 years after initial presentation.
Sézary syndrome is a rare, aggressive, cutaneous T-cell lymphoma characterised by widespread erythroderma, atypical peripheral lymphocytes (Sézary cells) and lymphadenopathy.
Cutaneous T-cell lymphomas typically present as indolent cutaneous eruptions and are often misdiagnosed at initial presentation, as the skin lesions mimic common dermatological disorders such as eczema or psoriasis.
