Telangiectases are lesions formed by persistent segmental dilatation of papillary plexus vessels of the skin that typically present as fine, bright, nonpulsatile red lines or netlike patterns. Palmar erythema commonly presents as symmetric, blanchable, slightly warm, nonscaling erythema, most frequently involving the thenar and hypothenar eminences of the palmar surface. Palmar telangiectases and palmar erythema both have primary cutaneous, systemic disease, neoplastic, infectious, and drug-induced etiologies. We describe a case of palmar telangiectases in a patient with Graves disease. We also describe the pathophysiology of palmar telangiectases and palmar erythema and present a literature review of their etiologies.
毛细血管扩张是由皮肤乳头层血管丛持续节段性扩张形成的病变，通常表现为细小、明亮、无搏动的红线或网状图案。掌部红斑通常表现为对称性、可褪色、略温热、无鳞屑的红斑，最常见于手掌表面的鱼际和小鱼际隆起处。掌部毛细血管扩张和掌部红斑均有原发性皮肤、全身性疾病、肿瘤、感染及药物诱导等病因。我们描述了1例格雷夫斯病患者出现掌部毛细血管扩张的病例。我们还阐述了掌部毛细血管扩张和掌部红斑的病理生理学，并对其病因进行文献综述。
