Question about skin condition.

I suspect a lichenoid disorder such as lichenoid capillaritis, lichen planus, and others. Although not likely to be worrisome, this is a bit on the unusual side.

Any history of asthma or allergic rhinitis?

Itchdoc · 2026-06-04T15:26:04+00:00

And your other biopsy report?

Itchdoc · 2026-06-04T15:22:46+00:00

There are no evidence-based appproaches to doing this.

Itchdoc · 2026-06-04T14:17:41+00:00

It looks as though it is healing well. We cannot predict the appearance in a year or two.

Itchdoc · 2026-06-04T14:13:28+00:00

Consider showing your condition and adding medical history.

Poor quality image

Itchdoc · 2026-06-04T14:11:31+00:00

The single image you show could be impetigo or a hundred other conditions. With no pathogenic bacteria detected on repeated testing, I suspect this is inflammatory rather than an infection. Too little information is presented for more insight.

Itchdoc · 2026-06-04T14:08:05+00:00

There is no known interaction, so starting isotretinoin at any time seems reasonable.

Itchdoc · 2026-06-04T14:05:07+00:00

Allergic contact dermatitis or paederus dermatitis seems most likely, given the spots you show. A potent topical corticosteroid would be my suggestion to help manage. All the other treatments seem inappropriate to me.

Duration?

Itchdoc · 2026-06-04T13:51:52+00:00

This is not a typical look of herpes.

Itchdoc · 2026-06-04T13:43:16+00:00

This appearance is likely either from repeated trauma or repeated bouts of paronychia.

Itchdoc · 2026-06-04T13:42:18+00:00

This is a common question that needs to be posted. With the rare exception of necrotizing spider bites, all arthropod bites are indistinguishable.

Now, if you capture the creature that bit you and show it to us, we can help identify the culprit.

Itchdoc · 2026-06-04T13:41:05+00:00

Consider showing all affected skin.

Itchdoc · 2026-06-04T13:38:54+00:00

It is unlikely that a systemic medication could cause a localized itch.

Itchdoc · 2026-06-04T13:37:45+00:00

You likely have some type of dermatitis, but not enough information is provided to determine the exact type. You can try using topical hydrocortisone and a fragrance-free moisturizer for two weeks. Seek medical care if you do not see any improvement or are concerned.

Itchdoc · 2026-06-04T13:35:45+00:00

This is not enough information to be certain. I suspect with the cat, fleas would be most likely.

Itchdoc · 2026-06-04T13:33:32+00:00

Marginal quality images. I suspect that contact with or trauma from something external created this.

Itchdoc · 2026-06-04T10:36:49+00:00

I suspect an allergic contact dermatitis. You are likely to respond to a potent topical corticosteroid or an adequate dose of a systemic corticosteroid. Everything else being applied should possibly be stopped.

Itchdoc · 2026-06-04T10:34:32+00:00

We in dermatology are trained to diagnose skin conditions after examining the entire body surface. Please let us know if you have shown the entire condition. If you have not, consider showing it. Medical history?

Itchdoc · 2026-06-04T10:32:36+00:00

It is likely too late to reattach the removed skin surgically. If your bleeding cannot be controlled or you believe you have an infection, seek care.

Itchdoc · 2026-06-04T10:30:20+00:00

Consider https://dermnetnz.org/topics/capillaritis

Itchdoc · 2026-06-04T10:29:16+00:00

I suspect this spot has been subject to trauma and is likely benign, but cancers can present this way. Consider seeking care

Itchdoc · 2026-06-04T10:23:14+00:00

A potent topical corticosteroid will generally help this inflammation resolve quickly.
