Rhinophyma is a condition causing development of a large, bulbous nose associated with granulomatous infiltration, commonly due to untreated rosacea. [1] The condition is most common in older white males.
A venous lake (also known as phlebectasis [1]) 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. [2] [3] [4] Lesions generally occur among the elderly. [5] [6]
Furthermore, mongolian spots, large birthmarks, and the consumption of food products with blue or purple dyes can also result in the bluish skin tissue discoloration and may be mistaken for cyanosis. [ 2 ] [ 3 ] Appropriate physical examination and history taking is a crucial part to diagnose cyanosis.
The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2]: 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread to the brain, causing cavernous sinus thrombosis, meningitis, or brain abscess.
Rarely, the nose, ears, nipples, or lips are affected. [1] The episodes classically result in the affected part turning white and then blue. [2] Often, numbness or pain occurs. [2] As blood flow returns, the area turns red and burns. [2] The episodes typically last minutes but can last several hours. [2]
The facial vein (or anterior facial vein) is a relatively large vein in the human face. It commences at the side of the root of the nose and is a direct continuation of the angular vein where it also receives a small nasal branch. It lies behind the facial artery and follows a less tortuous course.

The very term "acrocyanosis" is often applied inappropriately in cases when blue discoloration of the hands, feet, or parts of the face is noted. [1] The principal (primary) form of acrocyanosis is that of a benign cosmetic condition, [ 2 ] sometimes caused by a relatively benign neurohormonal disorder. [ 3 ]
