Transverse Nasal Stripe at Puberty (Stria Nasi Transversa)

Appraisal of transverse nasal groove: A study

“…[6] However, none of our patients gave similar history. In contrast to a higher incidence of TNG reported in children in previous western studies, [1,3] we observed it to be more common in 15-45 year (70%) age group; this implies that this is a condition of adolescents and adults. This observation is in concordance with report of Pavithran.…”

“…[1,2] They are well-demarcated grooves of 1-3-mm width and about 1-mm depth that extends transversely across the dorsum of nose, at the junction of upper two-third and lower one-third of the nose, just proximal to alae nasi. [3] They are more prominent in children and tend to improve spontaneously overtime during third and fourth decade of life and becomes less apparent and shallower; [3] finally by the end of fifth decade only a faint band of pigment may remain.…”

Transverse Nasal Line Associated with Congenital Persistent Milia

“…In both patients, cystic lesions were almost exclusively located along the nasal line, although in 1 patient a few similar lesions on the face were also noted [4]. In the original report of tranverse nasal line, Cornbleet [1] considered the transverse line as a result of differential growth of the nasal cartilages. He speculated that the nasal line develops at puberty, when the alar cartilages enlarged faster than the triangular cartilage of the nose.…”

“…In 1951, a transverse nasal line was first described by Cornbleet [1] as a peculiar reddish streak in a group of 5 girls and was labeled stria nasi transversa. It is important to recognize the nasal line as a localizing factor for comedones [2] and milia [3,4].…”

Pigmented transverse nasal band: A distinct presentation

“…Cornbleet in 1951 described a cutaneous defect, transverse nasal groove and termed it as transverse nasal line, stria nasi transversa, and transverse nasal strip . These are linear 1‐ to 2‐mm‐wide hyperpigmented band‐like eruption extending transversely over the dorsum of nose from end to end on both sides.…”
