Histology

HISTOLOGY


Three biopsies are submitted, processed and evaluated.


Block A, three sections, contains one section showing severe

pyogranulomatous folliculitis, furunculosis and dermatitis with

fibrosis. Large numbers of neutrophils, macrophages,


lymphocytes and plasma cells surrounding free keratin. The


other two sections reveal normal thickness epidermis with


nearly complete absence of follicular structures with minimal

sebaceous glands.


COMMENT


Histological evaluation is diagnostic for severe


pyogranulomatous folliculitis, furunculosis and dermatitis with

fibrosis in one section of hypotrichosis in the other sections.

Comedone formation is very commonly seen associated with


hypotrichosis and will correlate with the clinical history.


Rupture of a comedone leading to an autogenous foreign body


reaction towards the free keratin is suspected. Bacterial


folliculitis is another possible consideration.

Topical treatment might be helpful.

I'd think some good old-fashioned 2.5% benzoyl peroxide would be my preference.

The Dermapet one looks nice, but I note you can have a gallon(!) of Davis plain one for £65.

https://www.ebay.co.uk/sch/i.html?_odkw=paxcutol&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR11.TRC1.A0.H0.Xbenzoyl+peroxide+shampoo.TRS0&_nkw=benzoyl+peroxide+shampoo&_sacat=0

Any legal issues importing this? I assume that these products don't meet EU rules (Acnecide being about the only readily available benzoyl peroxide left, with others all disappearing in short space of time with "ingredient" shortage due to regulatory requirements), hence not marketed here unless on ebay etc, but presumably the responsibility to meet such regulations lies with the seller rather than the buyer? Anyone any real knowledge on this?

Antibacterials were tried in March, but in my opinion not long enough (10 days) and Synulox

There is likely bacterial folliculitis. not criticising decision to biopsy, but would do cytology / trial treatment (Bravecto, appropriate washes, possibly systemic antibacterials) first personally.

The red lesions are ruptured follicular cysts with reaction in surrounding skin I suspect. I wouldn't be for squeezing too much at the ones that aren't angry ;-)

No need to biopsy, these are large follicular cysts, common in Chinese Crested.

Yes there is a good chance that this is normal Chinese Crested skin, just an extreme version.

However it also chews its feet and has reddened ears and I have taken in one of the erupting lesions for good measure.

I dealt with a breeder for many years who bred beautiful versions, though none ever looked like this one.

My justification to the client was that there are at least 3 separate skin conditions going on, Crested skin, atopy and volcanic eruptions, the question remains 'how do we manage this?'

My other favourite anecdote is 'If I knew the answer, I wouldn't need to do the test'

God help you if it's also prone to mast cell tumours! I dealt with a Labrador who suffered from both conditions a few years ago and it was a nightmare telling which was which.

Did you squeeze any? I wouldn’t be able to help myself

The white areas look similar to milk spots or milia in people which are glands blocked with keratin.

The skin doesn't feel thin and no other signs of Cushings.

I took 3 biopsies so will post the results, probably next Tuesday

?Demodex? Can see comedones and often affects feet. Interested to see biopsy results, they might find some mites if they’re there.

Sebaceous plugs + some folliculitis? Definitely interested in the biopsy result!
