Traumatic ulcerative granuloma with stromal eosinophilia: a malignant-appearing benign lesion

Traumatic ulcerative granuloma with stromal eosinophilia (TUGSE) is an underreported diagnosis in dermatologic literature. Rapid expansion with an ulcerative clinical appearance often provokes fear of malignancy despite its benign nature. Traumatic ulcerative granuloma with stromal eosinophilia is thought to be a reactive tissue response to trauma, but CD30⁺ mononuclear cells within a TUGSE lesion suggests the possibility of an underlying lymphoproliferative disorder. This case highlights the clinical and histological features of TUGSE and provides a brief review of the literature addressing this debate. Knowledge of this condition, which uncommonly presents to the practicing dermatologist, is important in providing appropriate patient care and counseling. When correctly identified, unnecessary therapies and emotional stress can be avoided.
