Hydroxyurea-induced genital ulcers and erosions: Two case reports.

Hydroxyurea is a chemotherapeutic agent used for myeloproliferative disorders and sickle cell anemia that is well known to cause painful mucocutaneous ulcers, typically involving the legs or mouth. However, genital ulcerations due to hydroxyurea therapy are a rare, and likely underrecognized, adverse effect with only a few cases reported in the literature to date. Ulcers of the lower legs caused by hydroxyurea are associated with a diagnostic delay, and this is likely exacerbated in cases of genital ulceration due to a lack of awareness. Herein we present two cases of painful genital ulceration in patients on hydroxyurea therapy. In the first Case, an 87 year-old male with polycythemia vera developed an ulcer on the scrotum, which was assessed initially through virtual visits during the COVID-19 pandemic, and was refractory to topical and oral antibiotic treatments. The second case was a 79 year-old male with essential thrombocythemia and a history of persistent leg ulcers who developed erosions of the glans penis. Both patients experienced complete resolution within weeks of discontinuing hydroxyurea therapy. In conclusion, genital ulcers and erosions induced by hydroxyrea may be underrecognized in clinical practice, but if identified, withdrawal of hydroxyurea leads to quick resolution of these lesions and the associated pain.

Digital dermatopathology: The time is now.

To continue to provide expert specialized care during the COVID-19 pandemic, our dermatopathology service transitioned to a secure virtual microscopy platform. In our experience, this digitally-enabled dermatopathology practice revealed myriad benefits, including an improved diagnostic workflow and increased access to teaching. Whole slide imaging (WSI) is a related system that digitizes glass slides with high resolution and has been clinically validated for primary diagnosis. While WSI requires an initial institutional investment, its benefits include expanded access to subspecialized expertise and collaborations, digital histopathologic data generation for research, unification of patient clinical and pathologic information, and archiving of educational resources. The switch to digitally-enabled remote dermatopathology at our institution and across the United States presents a rare opportunity to critically examine newly implemented systems and to develop permanent digital solutions, thereby taking a leap forward for the benefit of patient care, research, and medical education.
