EP.WE.741Management of a giant extraocular sebaceous carcinoma during the COVID-19 Pandemic: a case report

Abstract

IntroductionSebaceous carcinoma is a rare malignant skin tumour of the sebaceous glands which is most frequently located in the ocular region (75% of cases). Prompt recognition and treatment is vital, as it bears a high mortality rate ranging from 9 – 50%. We present a rare case of a giant sebaceous carcinoma of the upper back, managed as a day-surgery case because of resource and safety restrictions due to the COVID-19 pandemic.Case reportWe present a case of a 58-year-old male patient with a giant lesion on his upper back measuring 13 x 13cm in size. Due to the COVID-19 pandemic, this was resected under local anaesthetic. The histology and immunohistochemistry confirmed the diagnosis of a giant sebaceous carcinoma. Resection margins were clear and subsequent investigations confirmed there were no metastases. The defect was reconstructed with Matriderm © and a split-thickness skin graft, achieving a satisfactory cosmetic outcome at 3 months follow-up.ConclusionThis is the first report which demonstrates the wide local excision under local anaesthetic for a rare presentation of a giant sebaceous carcinoma. This approach may be more widely utilised in the extraocular manifestation of this tumour, reducing the morbidity and length of hospital stay for such patients.
