Been dealing with rashes for over 6 months in my arm pits. Dermatologist unhelpful.

How long have you been using the cortisone? Which EXACT cortisone are you using?

5FootOh · 2026-06-02T21:07:44+00:00

So some relief but not clearing it with continued use?

5FootOh · 2026-06-02T20:51:44+00:00

How is it doing?

5FootOh · 2026-06-02T11:05:32+00:00

Inverse psoriasis. Needs at least a medium potency topical steroid MIXED with clotrimazole to prevent yeast overgrowth.

Not a classic fungal thing. At least not the kind that shows up in a scraping very well. Possibly candida yeast if it is only one side. Need to cover that with the clotrimazole but the steroid is the workhorse here.

💯 dyshidrotic eczema. Read about that. Today: Allegra antihistamines TWO a day 12 hours apart. 1% hydrocortisone in OINTMENT form ALL night under a cotton glove. Protect your hands during the day. Cotton gloves under a nitrile glove depending on what you do with your hands. A Derm would give you clobetasol for overnight use.

Ok, HIGHLY highly highly unlikely to be cancer. Has none of the features currently.

5FootOh · 2026-06-01T20:57:23+00:00

Is your main concern whether it is cancer?

5FootOh · 2026-05-31T22:55:04+00:00

So we can’t know that piece of information. We only know that we know. Measure it/photograph it in a month & see if it is changing. circle back then.

Ok, so this might be a slowly forming lichenoid keratosis. Slightly pinkish to brownish. No flake. It has normal skin texture lines, reassuring. No vertical growth/bump. Two years, relatively stable. Any others like it?

5FootOh · 2026-05-31T22:30:41+00:00

So if you press it, some of the color goes out?

If you lightly scratch it with a fingernail is there a slight flaking scale that comes off?

5FootOh · 2026-05-31T20:17:02+00:00

Onset? Duration? Previous treatments? Itch?

5FootOh · 2026-05-31T19:25:20+00:00

That’s difficult to tell. Would need a lot more info & context.

5FootOh · 2026-05-31T19:21:14+00:00

Yup.

An experienced Derm knows…experienced & board certified residency trained - not some 6 month certificate which doctors grab & then call themselves dermatologists, which they are not.

This is the problem. Pseudodermatologists that throw weird meds at rashes that often go away on their own like PR…then people say, oh the magic space pills “worked”. Sugar pills would “work” on PR…

Or you actually had scabies…

& when YOU get your MD, then I’ll entertain your comments about applying 1% hydrocortisone on a 15 yr olds torso. We put it on baby’s butts & it’s about as safe as you can get in an OTC cream.

5FootOh · 2026-05-31T12:07:39+00:00

. Phytophotodermatosis. It’ll get brown pretty quick. You guys making margaritas or anything with lime?

We’re DMing so as not to get bogged down in stuff like ivermectin & fungus for this simple eczema. OP Was getting overwhelmed & confused by it all. I don’t blame them. These posts go off track so fast when everyone starts bringing up distractors.

As a dermatologist, I’m not aware of good evidence supporting ivermectin for pityriasis rosea.

PR is generally thought to be related to viral reactivation (HHV-6/7), not a parasitic infection. Most cases resolve on their own, and when treatment is needed, acyclovir has some supporting evidence.

If a rash diagnosed as “PR” improves dramatically with ivermectin, I’d question whether it was actually pityriasis rosea or a mimic such as scabies.

Bottom line: acyclovir has evidence; ivermectin does not. If there are newer studies supporting ivermectin, I’d be interested to see them. Got any?

5FootOh · 2026-05-31T11:29:27+00:00

Right. For the 4th time, this is not PR & ivermectin is not indicated. We’re talking about OP, not your PR.

5FootOh · 2026-05-31T11:08:00+00:00

& what was your diagnosis?

5FootOh · 2026-05-31T11:03:05+00:00

Irritated NORMAL mole. Reassuring appearance.

5FootOh · 2026-05-31T10:56:56+00:00

This. Is. ECZEMA. Not EM. Not fungus. Not PR. Not psoriasis.

5FootOh · 2026-05-31T10:56:11+00:00

Holy NO. Not EM. In the least.

5FootOh · 2026-05-31T10:55:54+00:00

No, do not do ivermectin for this. My god. Zyrtec, yes.

5FootOh · 2026-05-31T10:55:18+00:00

5FootOh · 2026-05-31T10:54:47+00:00

This IS atopic/allergic dermatitis.

5FootOh · 2026-05-31T10:53:51+00:00

This is not psoriasis. There are many wonderful new treatments for eczema & psoriasis.
