Venous lake

A venous lake (which are also known as "Phlebectases"〔James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. Page 588. ISBN 0-7216-2921-0.〕) is a generally solitary, soft, compressible, dark blue to violaceous, 0.2- to 1-cm papule commonly found on sun-exposed surfaces of the vermilion border of the lip, face and ears.〔Habif, Thomas P. ''Clinical Dermatology: A Color Guide to Diagnosis and Therapy.'' Mosby, Inc. 2004. Page 825. ISBN 0-323-01319-8.〕〔Sauer, Gordon. ''Manual of Skin Diseases.'' Lippincott. 1985. Page 315. ISBN 0-397-50668-6.〕 Lesions generally occur among the elderly.
Though these lesions may resemble nodular melanoma, the lack of induration, slow growth, and lightening appearance upon diascopy suggest against it, and indicate a vascular lesion.〔Wolff and Johnson. ''Fitzpatrick's Color Atlas and Synopsis of Clinical Dermatology.'' The McGraw-Hill Companies. 2005. Page 192. ISBN 0-07-144019-4.〕 Additionally, lack of pulsation distinguishes this lesion of the lower lip from a tortuous segment of the inferior labial artery.〔
==Cause==
The cause is unknown; however it is thought to be associated with sun exposure, leading to a dilated blood-filled vascular channel〔 "...lined with a singled layer of flattened endothelial cells and a thin wall of fibrous tissue filled with red blood cells."〔
