PERIORBITAL BASAL CELL CARCINOMA

UPP 113

Introduction. See below Case presentation. See below Deviation From the Expected. See below Discussion. Basal cell carcinoma (BCC) is the most common periorbital malignancy. Their incidence can be reduced with the use of sun protection. BCC rarely metastasizes, however when left neglected and has been longstanding it can continue to grow and lead to significant local destruction, disfigurement and sometimes orbital invasion. Therefore, early detection of its clinical presentation is crucial in order to provide adequate and timely patient care. A skin biopsy is then required to confirm the diagnosis and determine the histologic subtype of BCC. Laboratory and imaging studies may be necessary when suspecting involvement of deeper structures. Treatment vary depending on the tumor size, depth and anatomic location. Moreover, surgical excision remains the standard of care for the majority of periocular malignancies, with Mohs micrographic surgery (MMS) being the preferred method of treatment. It provides a combination of high cure rate and tissue conservation but it is costly. The other treatment modalities include radiation therapy, chemotherapy, cryosurgery, electrodessication and curettage (EDC), topical medication and photodynamic therapy (PDT). Conclusion.
