Incidence and Time to Development of Malignancies Arising on the Scalp of Patients with Erosive Pustular Dermatosis Based on Sex: A Retrospective Analysis

Supplementary Figure 1. The electronic medical record at Penn State Hershey Medical Center was queried for patients with EPD (ICD-10 L98.8) from January 2000 to December 2021. Since the ICD-10 code is not specific for EPD, each chart was reviewed by the authors to confirm the diagnosis of EPD of the scalp. Supplementary Table 1 Association of immunocompromised status and time to malignancy. No statistically significant differences in time to malignancy development between immunocompromised and non-immunocompromised patients. Supplementary Table 2 Association of EPD treatment type and development of malignancy. No differences were noted between treatment type and development of malignancy. Supplementary Table 3 EPD treatment modalities based on sex. No statistically significant differences between treatment and sex were identified.
