Myoepithelioma, a generally benign tumor comprised of myoepithlial cells, is an uncommon salivary gland tumor. Myoepithelioma originates primarily in the parotid gland, but several isolated cases have been described. Although myoepithelioma has a benign nature, but there is a potential risk of malignant change and recurrence in case of incomplete resection. We acknowledge that benign myoepithel...

A 13-year-old spayed female dog had a mass in the left auricle. Grossly, connection between the mass and original auricular cartilage was not recognized. The mass was unencapsulated and contained multiple islands of mature hyaline cartilage and neoplastic adipocytes. The neoplastic cells comprised predominant mature adipocytes, scattered lipoblasts and irregular round to spindle cells with mode...

P REVIOUS reports have given a description of the cyclic changes in excitability of both auricle and ventricle of the dog’s heart (I, 2). It was found that the dog’s auricle is ‘vulnerable’ to fibrillation throughout the major dip area of the excitability-recovery curve (3). A study of ventricular vulnerability has now been made. Cats and turtles were used almost exclusively in this investigati...

Petrification of the auricle is a recognized and distinct pathological entity. This involves ossificationorcalcification of the auricular cartilage resulting in hardening of the auricle which is clinically evident on palpation and can be confirmed through radiological imaging. The aetiology of this unusual phenomenon is varied and includes both local and systemic causes. Systemic conditions ass...

In order to examine the mechanism of atresia in the small follicles of laying hens, changes of three enzyme activities, acid phosphatase, 3ƒÀ-hydroxysteroid dehydrogenase (3ƒÀ-HSD) and glucose-6-phosphate dehydrogenase (G-6-PD), during atresia were analyzed histochemically. Acid phosphatase activity in the follicular wall increased along with the tissue degradation in the process of atresia. Hi...

introduction: jejunoileal atresia (jia) is a common cause of neonatal intestinal obstruction and is a common surgical emergency. the aim of this study was to compare primary anastomosis without resection of the dilated segment with transanastomotic t tube jejunostomy (tatto) versus resection of the dilated segment without t tube as the control group for treatment of patients with jia. material ...

The aortas in 41 specimens of aortic atresia (ten with associated mitral atresia) were studied for the presence of coarctation of the aorta. The basic lesion, causing varying degrees of obstruction, was observed in 31 instances (75%), 24 minor, seven with major degrees of obstruction. In half, the aortic lesion lay proximal to the ductus, and in the majority of the remainder, opposite the ductu...

We encountered a rare case of gastroschisis associated with jejunal atresia and colonic atresia. In our case, the jejunal atresia was not discovered for 27 days after the initial abdominal wall closure. The colonic atresia was not discovered for 48 days after initial repair of the gastroschisis secondary to the rarity of the disorder. Both types of atresia were repaired with primary hand-sewn a...
