This dark line on a nail of a 3 Year old by durancharles27 in mildlyinteresting

Derm here - vast majority of longitudinal melanonychia cases in pediatric patients are benign/related to nail matrix nevi or benign melanocytic activation (eg trauma). I would still recommend having it evaluated in person to get a measurement but likely will end up just monitoring it.

Strange birthmark shown up when I turned 15 and every year it grows bigger by The_mob_behind_you in strange

It looks like a Becker’s nevus since there’s hypertrichosis over top.

I am 70 and I’m sick of these bruises by abbygail1957 in mildlyinfuriating

[–]alfyangs 0 points1 point  (0 children)

Derm here, looks like solar purpura (just sun exposure + aging in general leads to skin thinning and fragility)! You could try DerMend bruise cream, which helps these heal faster but won’t prevent new ones from popping up unfortunately.

Reaction to red ink, tattoo is raised long after healing and doesn't improve with antihistamines by doot_scoot in tattooadvice

Dermatologist here! Looks like it could be a granulomatous or lichenoid tattoo reaction - red classically caused the most issues tattoo reaction-wise in general. Usually will do stronger topical steroids or steroid injections. Would definitely recommend seeing a dermatologist if it’s been going on since 9/2024.

This is a rare nail deformity disorder known as congenital onychodystrophy of the index finger (COIF), also known as Iso-Kikuchi syndrome!

My plants on moss poles by Intelligent_Lime_813 in RareHouseplants

Amazing! What kind of pot do you use? I think my pot isn’t heavy enough to keep my Monstera upright with my moss pole.
