Abstract
BACKGROUND: Several studies have reported the clinical aspects of oral syphilis, but few papers have considered the involved immunoinflammatory mechanisms.
OBJECTIVE: To analyze the clinicopathologic features and expression of immunoinflammatory and vascular proteins in oral secondary syphilis.
STUDY DESIGN: Fifteen patients with oral secondary syphilis were included; histologic features were analyzed using hematoxylin-eosin-stained histologic slides and immunohistochemical reactions were performed against intercellular adhesion molecule 1 (ICAM-1), vascular endothelial growth factor (VEGF), and CD34.
RESULTS: Lesions presented as multiple plaques and ulcers mostly located on the tongue, lips, and palate. They were covered by a stratified epithelium of irregular thickness showing exocytosis associated with a subjacent plasma cell infiltrate arranged in perivascular and perineural patterns. ICAM-1 and VEGF were expressed on endothelial cells and leukocytes, and microvessel density was similar on the superficial and deep regions of the connective tissue.
CONCLUSIONS: Expression of immunoinflammatory and vascular proteins was intense, suggesting their participation on the pathogenesis of oral secondary syphilis.
