Histopathology Examination

A 1-year-old, castrated male mixed-breed dog presented with diffuse, purple lesions arranged in an irregular patchy pattern, with a slight elevation on the right hindlimb extending from the tarsus joint to the upper region of the thigh. Dermatological examinations and fungal and bacterial cultures revealed no infectious agents. The therapeutic response to antibiotics and antifungal agents was negative. A histopathology examination of the lesion revealed vascular proliferation with vasodilation and numerous varying-sized vessels. Mast-cell-dominated perivascular cuffing was also noted. The dog was diagnosed with cutaneous angiomatosis due to diffuse lesions and the histopathology findings of hemangioma.

A 3-year-old, male mixed breed dog with botulism and bilateral descemetocele was submitted to lamellar keratoplasty with equine renal capsule preserved in glycerin in the right eye and conjunctival pedicle graft in the left eye. The evolution was satisfactory in both eyes, but better in the eye receiving the equine renal capsule, because the corneal transparence was more evident in that eye. On the other hand, the surgical period was more quickly in the eye receiving the equine renal capsule because the preparation of the conjunctival pedicle before the keratoplasty was not necessary.

Diffuse dermal angiomatosis (DDA) is a benign, acquired, reactive vascular proliferation. DDA is clinically characterized by painful purpuric plaque with central ulceration. The histopathologic hallmark is diffuse proliferation of endothelial cells that are arranged interstitially between collagen bundles of the reticular dermis. DDA has been reported in association with peripheral atherosclerotic disease, arteriovenous fistula and heavy smoking. We report the case of a 49-year-old Asian male with DDA who presented with a painful stellate-shaped purpuric patch on the right thigh. Histopathologic examination showed proliferation of CD34-positive spindle cells in the dermis. Our patient underwent vascular bypass surgery along with tight control of cardiovascular risk factors, which yielded successful results.

The most common testicular neoplasms in dogs are seminoma, leydigocytoma and sertolioma, affecting middle--aged and elderly dogs, where cryptorchidism is a predisposing factor, as well as some breeds. It can occur alone or, less fren-quently, concurrently, generally affecting the same testicle. This study aimed to report the case of a non-cryptorchid 14-year--old mixed breed dog diagnosed with seminoma and sertolioma, each in a testicle. The animal showed an increase in scrotal volume, with no changes in other clinical parameters on physical examination. On ultrasound examination, it was possible to observe alterations suggestive of neoplasia in both testicles and prostatic alteration suggestive of benign prostatic hyperplasia. Complementary blood count and biochemical tests were performed and, as treatment, orchiectomy was performed. Fragments were collected from both testicles and sent for histopathological examination. Microscopy of the left testicle showed the presence of round cells, multiple and evident nucleoli, cells in different phases of mitosis and binucleation, these changes being compa-tible with seminoma. In contrast, in the right testicle, spindle and elongated cells (pseudo-lobular) were observed, presence of long cytoplasmic projections with rounded ovoid nucleus, spindle cells and degeneration of seminiferous tubules, compatible with sertolioma. It was observed that physical examination associated with ultrasound was efficient to detect the presence of neoplasms, being validated by histopathological examination. Orchiectomy was an assertive treatment indicated for this case.

Granulomatous Dermatitis

A distinctive periadnexal multinodular granulomatous dermatitis of unknown cause was diagnosed over a 6-year period in 22 dogs (13 males and nine females) aged 8 months to 10 years, purebred as well as mixed-breed. Nodules, usually more than two, started on the face and were often unaccompanied by signs of irritation. All dogs were otherwise healthy except a Viszla with bilateral anterior uveitis and a Basset hound with nasal congestion and sneezing. Microscopically, cutaneous lesions occurred in a periadnexal pattern, replaced sebaceous glands, coalesced, and extended into the subcutis and in more advanced cases through the panniculus carnosus. Infectious agents were not demonstrated by aerobic, anaerobic, or fungus cultures or by light or electron microscopy, nor were ectoparasites seen. Immunofluorescence and peroxidase-antiperoxidase techniques gave negative results for intraepidermal and basement membrane deposits of IgA, IgG, IgM, and C3. Lesions were unresponsive to a variety of antibiotics; they regressed spontaneously in two untreated dogs and rapidly in dogs given only corticosteroid therapy. Continuous low-dose corticosteroids were necessary in a few dogs to prevent recurrence.

Excessive Proliferation

Chronic equine proliferative pododermatitis (canker) is a chronic hypertrophic disease of the hoof, denoted by an excessive proliferation of the horn-producing tissues, which results from a dyskeratosis of the keratinocytes. It occurs mainly at the frog and sulci regions, but can sometimes also affect the heels, sole, bulbs or hoof wall. The etiology still remains unclear. Infectious agents such as anaerobic bacteria, viruses, spirochetes and fungi have been isolated from diseased tissues, but, moreover, an immune cause has been suggested, possibly related to a genetic predisposition. This report shows a case of a Brazilian Sport Horse, 10 years old, that had been affected on the right hindlimb for more than two years without a concise diagnosis. Success was achieved with the treatment consisting of oral prednisolone and topical Purple Mush®.

Fungal endophthalmitis is a serious and vision-threatening infection which requires an immediate and effective treatment approach. Our research aims to elucidate the histological effects of the intravitreal injection of the maximum safe dosage of voriconazole and micafungin on retina. Six albino New Zealand White Rabbits were used. In experimental animals, a solution of voriconazole (Group V) or micafungin (Group M) was intravitreally injected in the right eye, while in control animals, balanced salt solution was intravitreally injected in the left eye (Group C). Euthanasia was performed ten days post injection and the retina was removed and prepared for histological examination with a light and electron microscope. Eosin-hematoxylin staining did not reveal any pathological changes in any of the samples examined. The immunohistochemical staining for Tumor Necrosis Factor alpha (TNF-a) marker was detected as negative in all samples, while Interleukin 6 (IL-6) marker was detected as mild only in the group injected with voriconazole. Electron microscopy revealed several ultrastructural alterations in retinal layers in both groups of experimental animals. Histological retinal lesions, revealed with electron microscopy in the present investigation, raises the question of the safe usage of these antifungal agents in the treatment of fungal intraocular infections in the future.

Grass Awn

A 13-year-old male mixed-breed dog was examined because of hematuria and pyrexia. Ultrasonographic examination of the genitourinary tract showed the presence of a migrating grass awn in the right prostatic lobe. Laparotomy allowed, under ultrasonographic guidance, to remove entirely the migrating grass awn from the prostatic parenchyma. The recovery was uneventful and four months after the surgery the owner reported that the dog showed the complete resolution of the clinical signs and full return to normal activity. To our knowledge, this case report describes for the first time the clinical presentation, imaging findings, management and outcome for a dog with prostatic localization of a migrating grass awn.

Acquired acral fibrokeratoma (AAF) is a rare benign fibrous tumor. Its size is usually small (i.e., <0.5 cm). However, few cases with giant lesions (i.e., >1 cm) have been reported. A 17-year-old Saudi male presented to the Dermatology Outpatient Clinic of Aseer Central Hospital, Aseer Region, Saudi Arabia, with a painless rounded skin-colored exophytic nodule arising from the dorsal surface of the right middle toe, 1.7 cm in diameter. The tumor was surgically excised. Histopathology examination revealed a giant polyploid lesion, composed of massive hyperkeratosis, acanthosis, a core of thick collagen bundles and vertically oriented small dermal blood vessels. The diagnosis was giant AAF. There was no evidence of recurrence after surgical excision. AAF is a rare benign skin tumor which should be differentiated from other similar skin lesions. Surgical excision is the first line for treatment.

ABSTRACTCutaneous myxomas are rare benign neoplasms which are frequently associated with Carney complex (CNC). Although more than 500 cases of CNC are reported, there is no literature on cytologic diagnosis of Cutaneous myxomas. An 18-year-old male, with no significant family history, presented with multiple cutaneous swellings, largest measuring 15 cm on the right cheek. He also had spotty skin pigmentations, raised adrenocorticotropic hormone levels and recurrent cardiac myxomas. Fine-needle aspiration cytology from the right cheek and suprapubic swellings revealed paucicellular smears with abundant myxoid material in the background, admixed with fragments of spindle and stellate cells with bland nuclear morphology, and vascular proliferation in few fragments. There was no mitosis, necrosis, or any epithelial element. Hence, diagnosis of cutaneous myxomas in CNC was made which was confirmed on histopathology. This is the first report of cytologic diagnosis of multiple cutaneous myxomas in CNC and the largest cutaneous myxoma reported in literature.

ABSTRACT A 3 year old female feline of mixed breed was sent to the diagnostic imaging sector under suspicion of bleeding due to ovariohysterectomy. An abdominal ultrasonography was performed to confirm the initial suspicion. However, no signs of bleeding were found, instead it was observed that the left renal silhouette had two pelvises and was elongated and larger than normal. The right kidney was not found. Excretory urography was requested to evaluate the condition of the ureters. The final diagnosis was crossed renal ectopia with fusion in an asymptomatic cat with no changes in renal function.
