ABSTRACT
BACKGROUND:
The presence of a vascular, blue linear discoloration on the nasal root of infants and young children is a frequent incidental feature, rarely reported in the medical literature. It is related to the trajectory of the transverse nasal root vein (TNRV).OBJECTIVE:
To study the frequency and clinical characteristics of the vascular discoloration of the nasal root in children.METHODS:
A prospective study was performed to address the presence or absence of vascular discoloration of the nasal root in all children under 6 years of age attending a pediatric dermatology clinic from November 2022 to November 2023. Data on age and skin phototype (Fitzpatrick classification I-VI) were also collected.RESULTS:
Of 701 patients examined, 345 (49.2%) presented with a vascular discoloration of the nasal root. This was present in 97 of 193 (50.3%), 127 of 261 (48.7%), and 121 of 247 (49.0%) patients for the age groups 0-1, 1-3, and 3-6 years, respectively. The presence of vascular discoloration of the nasal root was more frequent in patients with lighter Fitzpatrick skin phototypes 49 of 69 (71.0%) phototype II, 157 of 290 (54.1%) phototype III, and 137 of 337 (40.7%) phototype IV.CONCLUSIONS:
A vascular discoloration of the nasal root is a frequent skin feature in infants and children, persisting at least until the age of 6. It does not constitute any medical problem aside from cosmetic concern and parents can be reassured of its benign nature. We propose the medical term "prominent TNRV" to describe this condition.Key words
