A 72-year-old Japanese female patient presented with an asymptomatic, white-colored, smooth-surfaced, firm papule 3 mm in diameter involving the mucosa on the posterior part of the right maxilla. An excisional biopsy specimen was diagnosed as an oral focal submucous elastofibromatous lesion. A review of the literature revealed very few documented cases of oral mucosal lesions characterized by accumulation of degenerated elastic fibers. Various oral lesions have histopathological features similar to those observed in cutaneous diseases, and the present case was a focal submucous elastofibromatous lesion in the alveolar mucosa.
一位 72 岁的日本女性患者因右上颚后部黏膜出现一个无症状、白色、表面光滑、质地坚实的丘疹而就诊，直径 3 毫米。切除活检标本诊断为口腔局灶性黏膜下弹性纤维瘤样病变。文献复习显示，仅有少数文献报道过以变性弹性纤维蓄积为特征的口腔黏膜病变。各种口腔病变具有与皮肤疾病相似的组织病理学特征，本例为牙槽黏膜局灶性黏膜下弹性纤维瘤样病变。
