Lobular capillary hemangioma (LCH) is a benign capillary proliferation with a microscopically distinctive lobular architecture, composed of small to medium-sized vessels of capillary type. Rarely, it originates from the mucosa of the nasal cavity, most frequently from the anterior nasal septum, turbinates, and nasal vestibule. Etiology is unclear, but previous investigations suggest that this lesion is associated with injury, hormonal factors, some viral infections, and therapy with some drugs. We present a case of LCH arising from the medial wall of the maxillary sinus in a 15-year-old boy, which was completely excised by preoperative embolization and endoscopic sinus surgery. To our knowledge, this is the second reported case of an LCH originating from the maxillary antrum. Etiology, pathogenesis, diagnosis, and treatment modalities of LCH were also discussed.

Backround: parotid hemangiomas are rare vascular benign tumors 0.4-0.6%.  Though capillary type of hemangiomas have been shown a good response to medical therary, cavernous hemangiomas usually require surgical excision. Case report and discussion: 11 years girl with failure of medical treatment for parotid cavernous hemangioma was evaluated and operated with superficial conservative parotidectomy at aimsr, Hyderabad. Review of literature: reports mostly tab propranolol to be treatment for the condition; it has guarded effect over cavernous hemangioma. Conclusion: cavernous parotid hemangioma though rare, treatment mostly remains parotidectomy after proper evaluation for its feeding vessels.

Over the past 30 years, diseases in the hoof area in cows are a very serious and actual problem for all dairy farming. During the treatment of purulo-necrotic diseases of fingers, particular importance should be given to the search of new means of facilitating the cleansing of the wound surface from purulent exudate, early elimination of inflammation and a more rapid formation of healthy granulation tissue in the wound and quicken the transition of the inflammatorydystrophic phase (hydration) in the regenerative phase (dehydration). This article shows the results of histological studies of selected tissue samples with puruo-necrotic ulcerative lesions in the hoof area against the complex therapy. The research was conducted on the basis of LLC PSK “Krasnaya Zvezda” of the Ulyanovsk region, on cows suffering from purulo-necrotic ulcers in the hoof area. The material for histological studies was selected after mechanical treatment of the limbs from the areas of affected soft tissues in the hoof area before treatment, on the 7th and 14th days, with subsequent fixation in 10 ... 12% formalin. The sections were colored using hematoxylin and eosin and Van Gizon staining. During conducted research it is established that when using biologically active Diotevin sorption preparation in complex treatment of orthopedic ill cows on histological level revealed weak evidence of the inflammatory process, changes of angiogeneses structure of granulation tissue in the form of increased vessel density, capillary type and number of fibroblastic cells with further proliferation of epithelial cells in the dermis with recovery of epidermis with signs of hyperkeratosis.

The aim of the study to evaluate the peculiarities of the aortic wall structure at the place of coarctation. Materials and methods: Studying of the aortic sections removed during operative correction at the place of constriction. 10 children at the age between 1 to 6 months were undergone the operation. Intraoperative aortic biopsy specimens were observed in 10% neutral formalin. Histologic sections were prepared in a conventional way followed by staining them with hematoxylin-eosin. Results: Histological examination in the areas of constriction revealed that the endothelium in all the preparations had poor expressiveness. The most significant changes were recorded in the middle layer of the aorta in the form of reduced development of elastic fibers, their fragmentation and chaotic arrangement. Angiomatosis with the formation of thin-layer small vessels by capillary type was found out. In all the preparations, areas of emptying of cells and fibers of the middle cover with the formation of cystic structures were revealed. Conclusions: The histological examination has revealed changes in the structure of the aorta wall, which may indicate the systemic nature of the lesion and make it possible to consider coarctation of the aorta to be a manifestation of systemic vasculopathy. The above-mentioned facts determine the need for a more detailed examination of children with the specified pathology at different stages of observation.

Abstract ENT surgeons frequently encounter a variety of neoplastic, non-neoplastic and inflammatory masses involving the nasal cavity, the paranasal sinuses or the nasopharynx. Among these, the angiomatous polyp or angiectatic nasal polyps are rare and account for 4-5% of all inflammatory nasal polyps. They have variable growth patterns and clinical features. In angiomatous nasal polyps, there is a prominent component of dilated capillary-type blood vessels. We present a review of the literature regarding the most important features of this pathology and an unusual case of a large angiomatous polyp arising from the maxillary sinus.

The hemangiomas are benign vascular malformations. There are two types of hemangiomas that may affect the central nervous system, the cavernous type and the capillary type. The last is most uncommon and its presentation at spinal epidural space is extremely rare. These lesions usually present with signs and symptoms of myelopathy, radiculopathy or cauda equine syndrome. Magnetic resonance imaging (MRI) is the examination of choice and the treatment must be surgical regardless of the presentation of the patient due to the risk of spinal cord compression.
