[Ti] Título:Aberrant effects of altrenogest and exposure to exogenous gonadotropins on follicular cysts appearance in gilts.

[Ab] Resumo:Research was conducted to determine the effect of altrenogest and exposure to exogenous gonadotropins on ovarian function in prepubertal and mature gilts. Crossbred, presumably sexually mature gilts (n = 51), were fed with altrenogest for 18 consecutive days and the day after the last feeding with altrenogest, gilts were treated with eCG and 72 hours later challenged with hCG. Animals were slaughtered on Days 10 to 13 of their gonadotropins synchronized estrous cycle. Ovaries were examined for the number of CL, number of follicular cysts, and presence of corpora albicantia. Gilts were divided into two groups: those possessing corpora albicantia (group A-mature; n = 36) and those without corpora albicantia (Group W-prepubertal; n = 15) on their ovaries. In addition, each group was divided into two subgroups depending on the presence of follicular cysts (AC and WC) or their absence (AO and WO). There was no difference between the number of CL in group A and group W. Presence of corpora albicantia determined percentage of gilts possessing follicular cysts (13.9% group A vs. 66.7% group W). Gilts without follicular cysts (AO plus WO; n = 36) had higher number of CL (P < 0.01) than gilts bearing cysts (AC plus WC; n = 15). Comparison AO-AC did not show significant difference (P = 0.075) between CL number in mature cyst-free and cysts bearing gilts. A prepubertal gilts not bearing follicular cysts (WO) had higher (P < 0.02) number of CL than gilts bearing cysts. A significant negative correlation between the number of CL and number of follicular cysts was found (r = -0.664; P = 0.007). There were no differences in blood plasma progesterone and estradiol concentration between cyst-free and cyst-bearing gilts. These results indicate: (1) a higher follicular cysts appearance in prepubertal than mature gilts challenged with altrenogest and exposed to exogenous gonadotropins and (2) a negative effect of follicular cysts on the number of CL (ovulations) in prepubertal gilts.

[Ti] Título:In situ carcinoma in a hybrid cyst: a case report.

[Ab] Resumo:Follicular hybrid cysts including two or more components of the epithelial skin adnexa are very rare. The epithelial lining of hybrid cysts varies, and either contains epidermis, and trichilemmal squamous epithelium, or other epithelia of the skin adnexa. Hybrid cysts may also be associated with neoplasia, such as in situ carcinoma, Bowen's disease and squamous cell carcinoma. A 37-year-old female was complaining of a cyst on her scalp. The unilocular cystic lesion was lined with markedly atypical squamous cells with trichilemmal differentiation. Marked nuclear and cytological atypia, pleomorphism, numerous mitotic figures and atypical mitosis was detected in the squamous epithelium. The epithelium of the cyst was also composed of ductal structures lined with cuboidal epithelium. Immunohistochemical staining was positive for cytokeratin 7 (CK7) in both squamous and glandular epithelium. Luminal staining was shown by carcinoembryonic antigen (CEA), although gross cystic disease fluid protein-15 (GCDFP-15) was negative in the glandular epithelium. In addition, p16 tumor suppressor gene was strongly positive in both the squamous and glandular epithelium. Overall, the unique cystic lesion reported contained pilar squamous epithelium with in situ carcinoma and eccrine ductal structures, which was interpreted as a hybrid cyst composed of in situ trichilemmal carcinoma and a ductal eccrine component.

[Ti] Título:Association between liver failure and hepatic UDP-glucuronosyltransferase activity in dairy cows with follicular cysts.

[Ab] Resumo:Uridine 5'-diphospho-glucuronosyltransferase (UGT) liver activity was measured using estradiol-17ß as a substrate in dairy cows with follicular cysts. The activity was significantly lower than that in dairy cows with normal estrous cycles (P<0.01). Liver disorders, such as fatty liver and hepatitis, were observed in half cows with follicular cysts, and liver UGT activity was lower than that in cows with normal estrus cycles. In addition, the liver UGT activity was significantly lower in dairy cows with follicular cysts without liver disorders than in dairy cows with normal estrous cycles. Therefore, the cows were divided into those with low, middle and high liver UGT activities, and liver disorder complication rates were investigated. The complication rate was significantly higher in the low- (78.1%) than in the middle- (22.2%) and high-level (8.3%) groups, suggesting that liver disorders are closely associated with the development of follicular cysts in dairy cows and that steroid hormone metabolism is delayed because of reduced liver UGT activity, resulting in follicular cyst formation. We conclude that reduced estradiol-17ß glucuronidation in the liver and liver disorders are associated with follicular cyst occurrence in dairy cows.

[Ti] Título:Application of an innovative technique for unilateral ovariectomy in dairy cows.

[Ab] Resumo:This report describes an innovative unilateral ovariectomy technique for the surgical treatment of follicular cysts in dairy cows. Five cows, with a diagnosis of follicular cysts, were submitted to unilateral ovariectomy via a paralumbar fossa approach, in standing position. The linear cutter proved useful for clamping the ovary, stapling the vessels and cutting in one stroke, thus reducing surgery times. After unilateral ovariectomy, all cows underwent heat 7-30 days after surgery, and three cows became pregnant. All cows showed increased milk production. The results of this case report showed that flank ovariectomy, performed in this way, is an efficient, low-risk technique for surgical treatment of follicular cysts in dairy cows.

[Ti] Título:A new insertion/deletion fragment polymorphism of inhibin-α gene associated with follicular cysts in Large White sows.

[Ab] Resumo:Ovarian follicular cysts are anovulatory follicular structures that lead to infertility. Hormones play key roles in the formation and persistence of cysts. Inhibins are heterodimeric gonadal glycoprotein hormones that belong to the transforming growth factor-ß superfamily. These hormones suppress the secretion of follicle-stimulating hormone. In this report, partial fragment of inhibin-α (INHA) subunit gene of Large White pig was detected from the genomic DNA by polymerase chain reaction. The sequence showed a 283 bp fragment insertion/deletion (I/D) polymorphism in INHA subunit gene. A total of 49 Large White sows with cystic follicles and 152 normal sows were screened for this polymorphism. The relationship of INHA I/D polymorphisms with follicular cysts was investigated. The distribution of I/D was significantly different between cystic and normal sows, thereby suggesting that the INHA subunit gene might be a potential biological marker for breeding programs in pig.

[Ti] Título:Benign follicular tumors.

[Ab] Resumo:Benign follicular tumors comprise a large and heterogeneous group of neoplasms that share a common histogenesis and display morphological features resembling one or several portions of the normal hair follicle, or recapitulate part of its embryological development. Most cases present it as clinically nondescript single lesions and essentially of dermatological relevance. Occasionally, however, these lesions be multiple and represent a cutaneous marker of complex syndromes associated with an increased risk of visceral neoplasms. In this article, the authors present the microscopic structure of the normal hair follicle as a basis to understand the type and level of differentiation of the various follicular tumors. The main clinicopathological features and differential diagnosis of benign follicular tumors are then discussed, including dilated pore of Winer, pilar sheath acanthoma, trichoadenoma, trichilemmoma, infundibuloma, proliferating trichilemmal cyst/tumor, trichoblastoma and its variants, pilomatricoma, trichodiscoma/fibrofolliculoma, neurofollicular hamartoma and trichofolliculoma. In addition, the main syndromes presenting with multiple follicular tumors are also discussed, namely Cowden, Birt-Hogg-Dubé, Rombo and Bazex-Dupré-Christol syndromes, as well as multiple tumors of follicular infundibulum (infundibulomatosis) and multiple trichoepitheliomas. Although the diagnosis of follicular tumors relies on histological examination, we highlight the importance of their knowledge for the clinician, especially when in presence of patients with multiple lesions that may be the cutaneous marker of a cancer-prone syndrome. The dermatologist is therefore in a privileged position to recognize these lesions, which is extremely important to provide further propedeutic, appropriate referral and genetic counseling for these patients.
