ReferencesVenous lake 是嘴唇的老年性血管瘤。它通常是由擴張的小靜脈形成的柔軟藍色腫塊，常單獨出現，觸感不硬。多發於長期曝曬於陽光的臉部與耳朵部位。46 歲男性就診時，發現下唇有一藍色腫塊，已生長 8 個月，起初很小，隨時間逐漸增大。患者否認外傷，也未曾無故出血或輕傷後出血。醫師檢查發現該腫塊柔軟且易被擠壓。於是採用液態氮冷凍療法，每次凍結病灶 10 秒，並在周圍留有一小塊邊緣，兩週一次。經過 12 週治療，病變已有改善。
A venous lake, sometimes referred to as senile hemangioma of the lips is usually a solitary, non-indurated, soft, compressible, blue papule occurring due to dilatation of venules. It is commonly found on sun-exposed surfaces of the face and ears. A 46 year old male patient presented with an 8 month history of a single, painless, bluish swelling over the lower lip which began as a pea sized lesion and gradually increased to the present size. Patient strongly denied any history of trauma at the site. No history of bleeding spontaneously or following minimal trauma could be elicited. On physical examination, a single, violaceous, soft, compressible, non-indurated, non-pulsatile papule was present on the lower lip. Patient was treated with cryotherapy with application of liquid nitrogen by dipstick method with one 10-second freeze-thaw cycle with a 1-mm margin. This was done at biweekly intervals. Some improvement was obtained following 12 weeks of therapy.

○ 治療
儘管可考慮切除，但通常無需治療，病變可自行觀察。
