[Sézary's syndrome. Case report]

Area of Science:

• Dermatology
• Hematology
• Oncology

Background:

• Sézary syndrome is a rare, aggressive cutaneous T-cell lymphoma characterized by erythroderma and circulating neoplastic T-cells.
• It is considered a late-stage manifestation of mycosis fungoides.

Observation:

• A patient with Sézary syndrome experienced persistent symptoms for five years.
• The disease culminated in sudden, fatal involvement of internal organs.

Findings:

• The exact nature of Sézary cells remains incompletely understood.
• Cytogenetic and immunological studies suggest Sézary cells are abnormal T-lymphocytes.
• Cytochemical data indicate a potential heterogeneity, with some cells exhibiting lymphocytic and others monocytic characteristics.

Implications:

• This case underscores the critical need for further research into Sézary cell biology.
• Understanding Sézary cell heterogeneity may lead to improved diagnostic markers and targeted therapies.
• Early detection and intervention strategies are crucial for managing this aggressive lymphoma.
