A 59-year-old male was admitted to the Department of Periodontology and Clinical Oral Pathology due to bilateral thickening of the buccal mucosa and dorsum of the tongue. His major complaints involved xerostomia and dysphagia to solids. He also reported frequent incidence of monocle haematomas after physical effort. Intraoral examination revealed the presence of bilateral submucosal thickenings on both cheeks and significant macroglossia with deep indentations on the margins of the tongue and depapillation of its dorsum (Fig. 1). Mobility of the tongue was markedly reduced. An incisional biopsy was taken from the buccal mucosa and underlying tissues.
Histopathological examination showed the presence of abundant amorphous eosinophilic deposits in the muscular part of the specimen (Fig. 2).
