Acral lentiginous melanoma mimicking benign disease: the Emory experience.

Background: Plantar and subungual melanoma exhibits a higher misdiagnosis rate relative to other anatomic sites. Misdiagnosis and delay in diagnosis are statistically associated with poorer patient outcome. Awareness of atypical presentations of acral melanoma may, thus, be important to decrease misdiagnosis rates and improve patient outcome.

Are keloids really "gli-loids"?: High-level expression of gli-1 oncogene in keloids.

Background: Keloids are a common lesion arising from sites of previous trauma and are a considerable source of morbidity because of continued growth of lesions, pruritus, and physical appearance. They consist of mesenchymal cells embedded in a stroma of disordered collagen matrix. Clinically, keloids are distinguished from scars in that keloids demonstrate continued growth over the borders of the original injury.
