<div><strong>Background: </strong>Mouse mammary tumor is a common neoplasm of the species. Mice is an established model for human breast cancer studies and in recent times for transgenic studies. Hemangiomas are tumors of blood vascular system. Hemangioma with breast cancer is reported in human beings. Presented study describes an unusual case of concurrent mouse mammary tumor and cavernous hemangioma from Mizoram, India.<br />
<br />
<strong>Methods: </strong>A mortality of 8 out of a colony of 25 female albino mice was observed due to mammary tumors. Dead mice were thoroughly necropsied and tissue samples were collected from different parts of each tumor mass and fixed in neutral buffered formalin. The fixed tissues were processed for hematoxylin and eosin staining by routine paraffin embedding, microtomy and staining protocol.&nbsp;<br />
<br />
<strong>Result: </strong>Gross examination revealed variable sized tumors on abdomen of affected mice. Histopathology revealed two different forms of mammary tumor <em>viz</em>, acinar and solid mammary carcinoma. Most peculiar finding was remarkable presence of large, endothelial lined cavernous spaces with presence of stagnant blood. These were diagnosed as cavernous hemangioma. Perusal of available literature did not reveal any report of cavernous hemangioma occurring with mouse mammary tumor, while it is found in other species including human beings.</div>

<div><strong>Background:</strong> Nasal tumours of dogs often pose a diagnostic challenge due to their similar clinical manifestations with other chronic diseases. Therefore, their definitive diagnosis requires use of different diagnostic modalities like radiography, computed tomography and rhinoscopy along with biopsy. The present study evaluates the clinical, rhinoscopic and computed tomographic changes in 20 dogs with intranasal tumours.&nbsp;&nbsp;<br />
<br />
<strong>Methods: </strong>Dogs brought with clinical signs suggestive of nasal cavity diseases were screened by radiography and computed tomography of skull followed by rhinoscopy and biopsy of nasal mucosa for diagnosing nasal tumours.&nbsp;<br />
<br />
<strong>Result: </strong>The intranasal tumours encountered were- carcinoma, transmissible venereal tumour and haemangioma. Clinical signs, haemato-biochemical, radiographic, computed tomographic and rhinoscopic changes in dogs with intra nasal tumours confirmed through histopathological studies are presented.&nbsp;</div>
