The treatment of pigmented lesions continues to evolve as new laser technology emerges and improvements in existing devices are made. The ability to treat pigmented lesions with greater efficacy and safety has resulted from recent advances in laser technology.

Background: Odontogenic keratocysts of the jaw are a central feature of basal cell nevus syndrome (BCNS) and arise from the basal cell layer of the surface epithelium. Although they are benign, they tend to be aggressive, with local invasion of bony structures, extensive growth, and potential for substantial disfigurement and speech dysfunction. Complete surgical resection is the current standard of care; however, the procedures are often technically challenging and are followed by high recurrence rates.Observations: We report the case of a 55-year-old man with a long-standing history of BCNS. Over a 25-year period, this patient had been treated for many basal cell carcinomas (BCCs). He also had multiple large odontogenic keratocysts in the mandible that had previously been treated using surgical, chemotherapeutic, and radiation treatment techniques. He had also undergone a right inguinal lymph node dissection after BCC metastasis was diagnosed within a lymph node. Owing to the recalci-

The following paper, co-written by an American alumna of a U.S.- based study abroad program at the University of Ghana, Legon, and a U.S.-based American professor specializing in International and Black Atlantic Studies, will explore one particularly freighted instance of the end of such assumptions, by addressing the American student presence at the University of Ghana, Legon. Examination of the Legon case will, we hope, be valuable for all study abroad professionals, because the American student presence at Legon challenges all of the traditional assumptions noted just above.

Cryotherapy with an integrated sensor for temperature control is an effective, safe, and precise treatment, allowing for a 100% short-term cure rate of AKs.
