Introduction
The hiperadrenocorticism (HAC), or Cushing’s syndrome, presents clinical signs and biochemical alterations because of chronic overexposure to glucocorticoids. When its origins are adrenal, we can mostly relate HAC with neoplasm presence, carcinoma or adenoma, and rarely with bilateral presentation.

Introduction
Vaginal tumors are rarely seen in dogs, despite that vaginal and vulval tumours are the most common neoplasms of the tubular reproductive tract in the bitch.
Objectives
A 6 years-old-mix breed neutred female dog was presented for 2 months history of hemorrhagic and ulcerated mass on vulva.
Methods
In vaginoscopic examination the mass was invaded
to the vestibule. Biopsy specimen was taken, and
canine histiocytoma was diagnosed by histopathologic examination. The dog was placed on the operation table in sternal recumbency with the rear legs over the end of the table. The operation table was slightly tilted to elevate perineal area. Following the incision around the vulva, and dissection was went on around corpus uteri. All the mass was with corpus uteri, vestibule and vagina were removed. Macroscopically tumor free small part of vagina mucosa with submucosal tissues which surrounds the urethral opening was preserved. After approximating the subcuticular tissues with simple continuous sutures free edge of remnant vaginal tissue sutured to the skin by the simple interrupted sutures. In this way urethroplasty was achieved without damaging external ori ce of urethra.
Results
There was no any complication related to the surgery, and dog was continence until 3rd month postoperatively.
Conclusions
The applied surgical technique was thought as lifesaving, improving life quality. Perineal approach to remove the vaginal vestibule and also corpus uteri can be suggested to the practitioners.
Objectives
The aim of the current study was to repot a case of successful treatment of laparoscopic adrenalectomy of adrenocortical carcinoma in a dog.
Methods
A 9-year-old beagle, bitch, 12 Kg weight, showed polyphagia, polydipsia, polyuria, pendular abdomen, thin and dark skin, lumbar alopecic areas and lethargy. Low-dose dexamethasone test was carried out then and showed cortisol concentrations higher than 1.5 μg dL-1, 50% lower than basal concentration 4 hours after dexamethasone application, and again after 8 hours
of application. The team also performed Endogenous ACTH dosing, obtaining value higher than 10 pg mL-
1. On abdominal radiographic examination, we noted mild adrenal enlargement, and by ultrasonography, it was possible to identify adrenal asymmetry and right adrenal enlargement (2.8 x 2 x 2.15 cm) in relation with the left gland (2 x 1 x 1.5 cm). As a treatment for adrenal neoplasm-dependent HAC, we performed the laparoscopic right adrenalectomy using three trocars.
Results
The dog had an excellent recovery, and the team discharged it 48 hours after the procedure. Its signs of hyperadrenocorticism disappeared about two weeks after the surgery. One year after having the procedure, the animal is well and has no signs of tumor recurrence and Cushing’s syndrome.
Conclusions
Laparoscopic adrenalectomy was effective of total right adrenalectomy as treatment form of an adrenocortical carcinoma.
