INTRODUCTION Nevoid basal cell carcinoma syndrome is a rare autosomal dominant disorder characterized by numerous basal cell carcinomas, odontogenic keratocysts of the jaws and developmental defects. The disorder results from mutations in the PTCH1 gene. CASE PRESENTATION A 15-year-old boy presented to our dental clinic with multiple jaw cysts. The patient had broad confluent eyebrows, a broa...

We here describe a case of solitary basaloid follicular hamartoma (BFH) : the case developing in company with senile lentigo on the nose. BFH is a relatively rare benign follicular neoplasm of undetermined etiology. Histologically, the specimen consisted of small-sized squamoid or basaloid cells and follicular germ-like cells in the periphery of the tumor nests. There were no infundibular cysts...

BACKGROUND Selective immunostaining for calretinin labels the innermost layer of the outer root sheath of normal hair follicles, which is difficult to distinguish with hematoxylin-eosin staining. OBJECTIVE The aim of this study was to determine whether immunohistochemistry for calretinin allows identification of cutaneous adnexal tumors with follicular differentiation towards cells of the out...

The aim of study was histological evaluation of oviduct and uterus mucosa in case of cystic ovarian degeneration in sows. Materials for evaluations were received after slaughtering of 294 sows at age of 2-5 years. Sows were eliminated breeding and culled due to reproduction disorders: anoestrus after weaning of piglets, return of estrus, small litters and due to age, number of birth, bad condit...

Relevance: Odontogenic jaw cysts of inflammatory genesis in children are a cavity formation the bone tissue with predominantly asymptomatic course. This clinical and radiological picture may be characteristic number different pathologies, which poses clinician task conducting thorough differential diagnosis. The purpose study: To perform retrospective analysis histological examination protocols...

A review of the histology of 332 ovaries from stillbirths and neonatal deaths within the first 28 days of life showed that follicular cysts, lined by granulosa epithelium and having a diameter greater than 1 mm on a microscopical section, were present in 113 infants. In 48 cases multiple cysts were present, while in 65 only a single cyst satisfying the criteria was found. There was an excess nu...

cyst wall, the type of keratinization, the presence of vellus or terminal hair shafts, and the relationship with adjacent skin appendages. 6 The most common cutaneous cysts are those originating in the pilosebaceous unit, with infundibular or epidermoid cysts and trichilemmal cysts being the most common. Hair shafts inside cutaneous cystic lesions are a rare finding, and terminal hair shafts in...

We investigated the therapeutic effects of a progesterone releasing intravaginal device (PRID) on cystic ovarian disease (COD) and reproduction performance of cows. The possible influence of PRID on metabolic and/or health status was also examined. A total of 40 Holstein-Friesian cattle, with ovarian cystic structures, > or =2.5 cm in diameter, persisting for more than 7-14 days, without a corp...
