This retrospective observational study will analyze adult patients (≥18 years) with a confirmed diagnosis of cutaneous T-cell lymphoma evaluated in the Dermatology Service of Hospital México between January 2019 and December 2025. Data will be obtained from electronic medical records (EDUS), including sociodemographic characteristics, clinical presentation, histopathological and immunohistochemical findings, disease staging, treatment modalities, and clinical outcomes.
Patients must have at least one documented dermatological evaluation and have received treatment, including skin-directed therapies and/or systemic therapies. Records that are incomplete, inconsistent, or lack histopathological confirmation will be excluded.
The study aims to characterize local epidemiological and therapeutic patterns and describe clinical outcomes using descriptive statistical analysis, providing updated real-world evidence to support clinical decision-making and optimize management strategies for cutaneous T-cell lymphoma in a national referral center.
