Abstract

A 48-year-old woman presented with a submucosal, slow-growing tumor of over 1.5 cm in the left upper lip. The enucleation was performed in local anesthesia and after a curved incision cranial to the tumor. The histopathology showed an encapsulated tumor with three diagnostic components: 1) epithelial (ductal) component forming the inner layer of cysts and tubules, 2) myoepithelial cells as their outer layer and 3) myxoid mesenchymal stroma. The healing was uneventful and only a thin scar on the mucosa was visible in the follow up. Pleomorphic adenoma of the minor salivary gland are less common than those of the major salivary gland, with the upper lip being the second most localisation after the palate. Enucleation is the treatment of choice, with care taken to ensure the pseudocapsule remains intact.

[上唇多形性腺瘤]。
48岁女性,左上唇黏膜下生长缓慢,肿瘤超过1.5厘米。在局部麻醉下,在肿瘤颅侧的弯曲切口后进行去核手术。组织病理表现为包膜性肿瘤,有三个诊断成分:1)上皮(导管)成分构成囊肿和小管的内层,2)肌上皮细胞构成其外层,3)粘液样间充质间质基质。愈合顺利,随访时仅在粘膜上可见一薄疤痕。小唾液腺的多形性腺瘤比大唾液腺的多形性腺瘤少见,上唇是仅次于上颚的第二大腺瘤。去核是治疗的选择,要注意确保假包膜保持完整。
