I have seen previously cases like this that have panniculitis associated with pancreatitis.

See below for histopathology report:

I saw him back today and he had 2 new abscesses.

Blood tests done today: all normal.

Will go for steroids and add ab to treat infections above just in case.

Histology

DESCRIPTION: Biopsy from abscess on left thoracic wall x 1. The tissue examined comprises skin with a deep dermal to hypodermal mass composed of a cavity containing loose neutrophils and macrophages. The cavity is surrounded by granulation tissue and fibrotic tissue which is densely infiltrated by lymphocytes, plasma cells, macrophages and further neutrophils. Affected tissue extends to the margins of the sample examined.

DIAGNOSIS: Pyogranulomatous inflammation.

PROGNSIS: See below.

COMMENT: The appearance is consistent with an area of pyogranulomatous inflammation. The underlying cause is not apparent in the sections examined although could include a ruptured follicle perhaps secondary to a local pyoderma, ruptured follicular cyst or foreign body penetration combined with bacterial infection. Full excision should be curative, although culture and sensitivity of any residual affected fresh tissue may be advisable.

sounds like a pyrogranulomatous syndrome , maybe worth looking at Calcium , the other odd presentations that spring to mind are mycosis fungoides chronic cutaneous lymphoma / NME / infected calcinosis cutis cysts, HAC.

Thanks, all for your comments. I am still waiting for the histology report. I'll let you know when I get it.

no foreign bodies, no history of bite wounds. First couple I don't know where they were, because I was not seeing the dog at the time. last couple were one on back leg near popliteus, one over hipbone asnd last on thoracic wall.

Had a similar case years ago ,finally removed one lump in toto and send off for histopathologie ,tuned out to be steroid responsive condition

Another whose first thought was panniculitis. What did the histo say?

Are the abscesses in any sort of pattern? eg tracking FB (grass seed)

I would also be thinking immune-mediated panniculitis and probable steroid-responsive condition.

I had a sheltie with recurrent firm skin swellings( mainly over outer thighs and lumbar area) that burst with pus, left craters that then scabbed over. We referred and if was believed to be panniculitis and treated with prednisolone. I can't remember what the culture was.
