Abstract

Objectives: Pleomorphic adenomas are benign tumors that rarely involve nonsalivary glands. We report an uncommon case of ala nasi pleomorphic adenoma. We discuss the clinical and histopathologic characteristics, and review the literature on nasal pleomorphic adenoma.

Method: A 20-year-old man presented with a painless slow growing lobulated mass located on the right ala nasi extending into the nasal vestibule.

Results: Complete surgical excision was performed. Histologic examination found a mixed cellular component: epithelial and myoepithelial cells with chondromyxoid stroma. This was consistent with the diagnosis of a typical pleomorphic adenoma. There was no evidence of recurrence at 18 months after the surgery.

Conclusions: Pleomorphic adenomas located in the external nose are extremely rare. In such case, pleomorphic adenoma could originate from ectopic minor salivary gland. Complete surgical excision with long-term follow-up is recommended due to the potential risk of recurrence and malignant transformation.

鼻窦多形性腺瘤1例报告。

目的:多形性腺瘤是一种很少累及非唾液腺的良性肿瘤。我们报告一例罕见的鼻翼多形性腺瘤。我们讨论了鼻多形性腺瘤的临床和组织病理学特点，并对文献进行了综述。方法:一个20岁的男人提出了一个无痛的缓慢增长的分叶状肿块位于右侧鼻翼延伸到鼻前庭。结果:手术完全切除。组织学检查发现混合细胞成分:上皮细胞和肌上皮细胞伴软骨粘液样基质。这与典型的多形性腺瘤的诊断一致。术后18个月无复发迹象。结论:位于鼻外侧的多形性腺瘤极为罕见。在这种情况下，多形性腺瘤可能起源于异位小涎腺。由于潜在的复发和恶性转化的风险，建议完全手术切除并长期随访。
