Intestinal hemangiomas in 8 horses.

This retrospective study describes 8 cases of intestinal hemangioma diagnosed in horses during postmortem examination or surgical biopsy at the University of Tennessee College of Veterinary Medicine. In all cases, the intestine was the sole organ affected, and lesions were focal (3/8) or multifocal (5/8). Nodules were most commonly within the small intestine (7/8), particularly the jejunum (5/7). One case was in the left dorsal colon, which is the first report of hemangioma in the large colon of a horse. Lesions were discrete, raised, smooth, black to red, and ranged from 2 to 15 mm in diameter. Microscopically, all lesions were cavernous type and mural, most frequently within the muscularis (6/8). A majority of cases occurred in middle aged to older horses (average age of 19.3 years), and no breed or sex predilections were identified. The hemangiomas were considered incidental findings.

HEMATURIA AND URINARY BLADDER LESIONS COMPATIBLE WITH BRACKEN FERN (PTERIDIUM AQUILINUM) INTOXICATION IN CAPTIVE FALLOW DEER (DAMA DAMA)

Hemangiosarcoma, hemangioma, transitional cell carcinoma, and chronic cystitis were diagnosed in the urinary bladder of six captive fallow deer (Dama dama). Hematuria and thin body condition were observed in the advanced cases. These findings were compatible with chronic enzootic hematuria and were suspected to have been induced by chronic ingestion of bracken fern (Pteridium aquilinum) present on the premises. These lesions were similar to those described in bovine enzootic hematuria in cattle. Hemangiosarcoma metastases, hydronephrosis, and renal carcinoma were also associated in some cases. This is the first report of hemangioma, hemangiosarcoma, transitional cell carcinoma, and renal carcinoma of the urinary bladder in fallow deer and the first indication of bracken fern intoxication in deer.

Cavernous Hemangioma With Large Phlebolith of the Parotid Gland

Hemangiomas are vascular anomalies characterized by increased proliferation and turnover of endothelial cells. Hemangiomas of the parotid region are relatively uncommon in adult population, and there are a few reports of hemangioma with large phlebolith within the parotid gland. We herein report a case of it. Sialography may be a useful investigation method in the evaluation of radiopaque lesions localized intraglandularly in the parotid area to rule out the sialolith. Cavernous hemangioma with phleboliths should be included in the differential diagnosis of a swelling in the mandibular area.

Doppler Ultrasound for the Diagnosis of Intraparotid Hemangioma

Much controversy exists regarding the origin of hemangiomas. Most investigators believe them to be hamartomas. These lesions have been found virtually in all the organs in human body, but the head and neck area appear to be involved more frequently than other regions. Hemangiomas are rarely found in the salivary glands. The identification of salivary gland hemangiomas requires a minimum of ultrasound examination along with color Doppler. One such report of hemangioma of the parotid gland is reported, which was diagnosed with the aid of color Doppler ultrasound examination.
