BACKGROUND: The clinical and pathological features of lymphomatoid papulosis (LYP) are diverse. The objective of this study is to evaluate the clinical and pathological features associated with the prognosis and clinical course of LYP.
PATIENTS AND METHODS: The clinical and pathological features of LYP in a medical center database were retrospectively retrieved.
RESULTS: Overall, 58 LYP patients were included in the study. The mean age at diagnosis was 39.1 years and the female-to-male ratio was 1:1.2. More than two-thirds (40/58, 69.0%) of the patients showed a chronic and recurrent disease course. A longer pre-diagnosis duration (odds ratio (OR), 1.01; 95% confidence interval (CI), 1.00-1.03) was significantly associated with secondary lymphoma development. Lower extremity involvement (OR, 10.40; 95% CI, 1.17-92.28) and the absence of eosinophils in the lesions (OR, 11.28; 95% CI, 1.01-126.24) were found to be significantly associated with the chronic and recurrent course of LYP.
CONCLUSION: A longer pre-diagnosis duration is associated with secondary lymphoma, while a lower extremity involvement and the absence of lesional eosinophil infiltration are associated with the chronicity of LYP.
