Supplementary Material for: A Rare Case of Lymphoepithelioma-like Carcinoma of the Skin on the Chest: A Case Report

Introduction: We present a case of lymphoepithelioma-like carcinoma of the skin (LELCS) of the chest identified in an elderly white male. We discuss the management and various treatment options for this rare type of cutaneous malignancy and highlight treatment uncertainty for this uncommon skin cancer, and the need to balance the best patient outcomes with minimal treatment morbidity.
Case Presentation: Our patient presented with a waxing and waning erythematous rash on his chest for two years. After a shave biopsy revealed lymphoepithelioma-like carcinoma, the patient underwent wide local excision and six weeks of radiation therapy due to the identification of adverse pathologic features.
Conclusion: Overall, this case shows the diverse range of LELCS presentations and available treatment options and highlights areas of clinical treatment uncertainty and areas for future therapeutic development.
