Here's the actual report content from the visit.  The biopsy was done at a different vet.  Not sure if the garbly goop below says what it is or not.  It is not malignant, but supposedly will come back if any of it is missed.  When he manipulated it, it caused him to flinch in pain.  His amputation surgery is tomorrow, should have him home Wednesday, maybe Thursday.

Presenting Complaint: Right forelimb lameness suspected secondary to a previously diagnosed benign ossifying

tumor of the right shoulder joint.

Physical examination: On presentation, Scooby was bright, alert and responsive. He had a grade 3/5 right forelimb

lameness. He was painful to direct palpation of the right medial aspect of the glenohumeral joint. A 3cm in diameter,

firm, fixed mass was palpated on the medial aspect of the right shoulder. No other orthopedic abnormalities were

palpated.

Diagnostics:

Right forelimb radiographs - Proliferative bony opacity on the medial aspect of the glenohumeral joint.

Pelvic radiographs - No signs of hip dysplasia. A metal opacity (safety pin) was noted in the colon.

Diagnosis: Right medial shoulder mass - suspected benign ossifying tumor

Treatment/Plan:

Scooby presented for surgical consultation of a benign ossifying tumor of the right shoulder which was diagnosed on

Jamshidi biopsy. Curative intent surgery for this benign mass necessitates complete surgical excision. Possible

causes of a benign ossifying tumor include osteoma, chondroma, multilobular osteoma and chondroma,

osteochondroma, and enchondroma. Depending on tumor type, varying degrees of local invasion are seen with such

tumors. Given the location of the mass and close proximity to vital structures, wide margin resection may compromise

the joint and surrounding structures. The two surgical options are marginal resection with the risk of regrowth or

amputation. CT scan is recommended to closely identify the margins of the mass if local excision is elected for. The

mass will be submitted for histopathology to confirm the relative grade. The results will dictate further treatment such

as chemotherapy. At this point the Clements would like to consider the possible options and will call if they would to

schedule surgery.

Well, Scooby had his surgery this morning.  Surgeon called me around lunch and he said it went perfect.  They're sending the tumor off to have it identified for sure.  I'm not sure why that wasn't done with the original biopsy.  Grrrr...  I'll switch future posts over to the Treatment and Recovery.  

I sure miss that silly dog right now.  I'll hopefully get him home tomorrow, but maybe in two days depending on how he's doing.  One of the ladies at work who has never met him cried.  A bunch of Facebook friends are private messaging me worried about him.  I'm glad it's done and I can quit dreading it.  I just want him home.

Just following up.  9 days post amputation, I got the pathology back.  It was calcinosis circumstricta - metastatic calcification.  Apparently it's something German Shepherd Dogs get.  It was in the joint and causing pain, amputation was the correct treatment.  No chemo needed thank goodness, after the testimony of folks experiencing chemo on here.  

He's running around on three legs, acting a fool, trying to keep him from over-do'ing it.  Sky is the limit.
