1/14 #Men and #women experience disease differently. This is reminiscent of #SyndromeX and other chronic disease like #MECFS, #slow #virus manifestations, and even #LongCovid and post-acute sequelae of #SARSCoV2.

You've seen rashes and called them all "maculopapular," because, why not?

Macules are flat lesions, less than 1 cm in diameter.
If you closed your eyes and ran your finger over it, you wouldn't feel where it starts and stops.

Papules are raised (or depressed) lesions, less than 1 cm in diameter.
Unlike macules, if you closed your eyes and ran your finger over it, you'd be able to tell where the lesion is.

Time for another #morphology #Derm101 series #tweetorial on the skin exam. Today, we'll cover:
DISTRIBUTION
How the location a rash occupies on the body might help us with the differential diagnosis!

An important point to start:
Distribution is LEAST important in the skin exam. Primary & secondary lesions, configuration & scale are all better in informing our DDx.
I tell my learners that if confused about a rash, pretend it's elsewhere on the body & see if that helps.

Also - throughout this #tweetorial, I will try to display skin disease in lighter & darker skinned patients side by side. Remember in darker skin, erythema is harder to see, so I hope this highlights the point!
A question: In tweet 1, what distribution is shown in the photo:

First off, if you haven't gone through the primary lesion #tweetorial yet, it's a good idea to start there. Here's the link:
As review, these are the different primary lesions👇

Secondary lesions are the changes that affect the primary lesion.
Say what? If a papule is scaly, the SCALE is the secondary lesion. If a plaque is crusty, the CRUST is the secondary lesion.
A question: What was the secondary lesion seen in the pic from the 1st tweet?

Why are #dermatologists so obsessed with description?
Well, for us, morphology is everything. We start with the exam and take the history afterward based on the possible differential we've come up with!
So let's start simple. What was that lesion in the prior tweet?

That was a PATCH of vitiligo.
PATCHES are flat lesions >1 cm wide, whereas MACULES are flat lesions <1 cm wide! Check out photo #1 of perioral vitiligo where macules are coalescing into patches!
In #2, you can see both macules and patches in these Cafe au lait lesions.

Male #GCNs grow ornamental crests every year during aquatic breeding period.
As UK seasons become less distinct, #pond arrival times are less predictable.
So what is happening with #crest development?🧐

We photographed >100 individual #newts over 2 breeding periods and tracked changes in crest size + shape using #ImageJ software.
Does early arrival = Early growth peak?
Or ⬆ growth period i.e. potential mating advantage?

Around 3000 BCE in eastern #Europe, a Proto-Balto-Slavic #language started to diverge from #ProtoIndoEuropean.
The #Slavic branch of the #IndoEuropean #languages began about 2,000 years later when Proto-Slavic deviated from Proto-Balto-Slavic.

As the #Slavic-speaking area expanded during the first millennium CE (striped area on map), Proto-Slavic transitioned to Common Slavic. The #language underwent minor changes that occurred mostly uniformly across eastern #Europe, thereby maintaining mutual intelligibility.
Around the year 1000 CE #CommonSlavic began to split into the South, West, and East branches to which all modern #Slavic #languages belong.
Roughly 315m people speak a Slavic #language, mostly in Eastern #Europe (including the #Balkan peninsula), #CentralAsia, and #Siberia.

Before we get too far into it, how do we think about #scale? Meaning, which one of the following is it?

When we say "primary lesion," we mean the most basic element of a lesion/rash (papule, macule, patch, plaque etc).
SECONDARY CHANGE (which scale is) means the extra exam element that occurs on top of the primary lesion!
Tertiary/Quaternary isn't a thing. I'm just a jerk.
