| Abstract | This report describes two cases of oral localized amyloidosis (LA). In case 1, a 52-year-old man appeared with painful slightly, yellowish multiple nodules located on the dorsum of the tongue, of unknown duration. Incisional biopsy was performed, and the histopathologic analysis revealed a homogeneous, eosinophilic, and extracellular material. Congo red stain showed salmon pink coloration at light microscopy and apple-green birefringence at polarized light. In case 2, a 74-year-old man presented asymptomatic nodular lesions on the labial commissures with duration of several months. An excisional biopsy was performed in both lesions, and microscopically the specimen demonstrated the same histopathologic features of the case 1. Furthermore, amyloidosis with systemic involvement was excluded after investigations for both patients. Thus, the final diagnosis for both cases was LA. The patient 1 refused the surgical excision of the residual lesion, and in both cases, no signs of clinical and systemic progression were observed after 24 and 84 months of follow up. Although it is rare, LA should be considered in the differential diagnosis of multiple or single yellowish nodules on the oral cavity. |
