摘要

黏液瘤可归类为良性牙源性外间质病变，以中心型和外周型为多见。本病例报告了一名35岁黑人女性的无症状结节性生长，导致面部不对称和上颌前牙咬合困难。通过根尖周围x线和锥形束断层扫描证实病变为外周性。鉴别诊断包括非肿瘤性增生过程。切除活检，组织病理学分析显示肿瘤有中间黏液样和纤维间质，有星形和卵形细胞，伴有局灶矿化，无牙源性上皮。阿利新蓝染色显示粘液样成分。最终诊断为外周纤维黏液瘤。患者随访6个月无复发。

Peripheral fibromyxoma: a case report focusing on differential diagnosis

Myxomas can be categorized as benign odontogenic lesion of ectomesenchyme, with the central and peripheral variants, being the last one much more uncommon. This case reported a nodular asymptomatic growth affecting a 35-year-old black female, causing facial asymmetry and difficulty in occlusion on anterior maxilla. The lesion was peripheral confirmed by periapical X-ray and cone beam tomography. Differential diagnosis included non-neoplastic proliferative processes. An excisional biopsy was taken, and histopathological analysis indicated a neoplasm with intermediate myxoid and fibrous stroma and with stellate and ovoid cells associated with focal mineralization without odontogenic epithelium. Alcian Blue staining revealed myxoid composition. The final diagnosis was peripheral fibromyxoma. The patient is following up without recurrence after 6 months.
