Abstract
Conjunctival myxoma is an exceptionally rare, slow-growing, benign neoplasm of primitive mesenchyme origin. Forty-one cases of conjunctival myxoma from a literature review, including the authors' case, are listed. The usual clinical history is a painless mass appearing during months to years. Grossly, the tumor is a well-circumscribed, cystlike, gelatinous, yellow-to-pink, translucent-to-solid mass. Microscopically, the hypocellular tumor contains stellate- and spindle-shaped cells in a mucoid stroma with abundant hyaluronic acid mucopolysaccharides. Vimentin and α-smooth muscle actin highlight the spindle and stellate cells. S100 protein and desmin are negative for the tumor cells. Treatment is complete surgical excision, with no recurrence reported in the follow-up period. Notably, conjunctival myxoma may be associated with Carney complex, an autosomal-dominant disorder associated with skin pigmentation, endocrine abnormalities, and myxoma of the heart and eye. Physicians should appreciate this unique ocular tumor because of its potential association with Carney complex.
摘要
结膜黏液瘤是一种很少见的、缓慢生长的、良性间叶源性肿瘤。
材料与方法:对来自文献及作者个人收集的41例结膜黏液瘤进行文献回顾。
结果:临床病史多为无痛性肿物数月或数年。大体,肿物界限清楚,囊样、胶状、黄-粉色、半透明-实性。镜下:细胞稀疏,富于透明质酸粘多糖的黏液样基质中见星形、梭形细胞。星形-梭形肿瘤细胞免疫组化表达vimentin和SMA,不表达S100和desmin。治疗采用完整外科手术切除,随访期间未见复发的报道。值得注意的是,结膜黏液瘤可能与Carney综合症相关,后者是一种常染色体显性疾病,由皮肤色素沉着、内分泌功能异常和心脏及皮肤黏液瘤组成。
结论:医生们应该注意到这种独特的眼部肿瘤,它可能与Carney综合症相关。
