Introduction: Squamous cell carcinoma (SCC) is a rare complication of long-standing discoid lupus erythematosus (DLE). The reported risk factors associated with the malignant transformation include chronic inflammation, scarring, immunosuppression, and the dysfunctional healing already evident in discoid lesions. If underdiagnosed and left untreated, this may lead to higher rates of recurrences, metastases and death. Objective: The main objective of this article is to report the diagnosis and management of a DLE-associated SCC on the upper lip of an elderly Filipino female. A short discussion on the pathogenesis and treatment of this disease entity is also presented.ugs/topical medications, family history and accompanying systemic symptoms were reviewed and analyzed. Case: A 78-year-old female, pawid maker, developed a rapidly growing verrucous tumor measuring 4.0 x 2.0 x 2.0 cm from a depigmented atrophic plaque located on the upper lip. Initial histopathologic findings were consistent with SCC and DLE. Considering the tumor size and the challenging anatomical location, the surgical oncology and plastic surgery team carried out a wide excision with 5 mm margin of the entire upper lip mass and surrounding plaque, followed by lip reconstruction. Biopsy findings of the excised mass were consistent with the initial findings. Three months post-operation, there was significant wound healing with no recurrences. Conclusion: Although the incidence is rare, SCC occurring in DLE is considered to be high-risk and should warrant early recognition and prompt treatment. In this paper, the authors also highlight the use of a standard wide excision in lieu of Mohs Microscopic Surgery as an alternative option where resources are limited.
