Anatomy and histomorphometry of accessory reproductive glands of the Black Bengal buck

The Black Bengal buck has a notable goat genetic resource. Seminal fluids from male accessory reproductive glands contain nutrients and other substances necessary for the optimum motility and fertility of spermatozoa, and act as a buffer against excess acidity of the female genital tract. This study was conducted to understand the anatomy and histomorphometry of accessory reproductive glands of the Black Bengal buck of Bangladesh. Anatomical study was performed immediately after euthanasia, and histomorphometrical study was performed by Hematoxylin and Eosin staining. There was a difference in biometric values between right and left accessory reproductive glands within the same buck. The average length, width and weight were 1.653 ± 0.025 cm, 1.146 ± 0.015 cm and 1.486 ± 0.010 gm, respectively for the vesicular glands, and 1.045 ± 0.037 cm, 0.918 ± 0.042 cm and 0.537 ± 0.029 gm respectively for the bulbourethral glands. The secretory units of the vesicular glands were lined by pseudostratified columnar epithelium consisting of tall columnar type cells and short basal type cells. The vesicular secretion was stored in the lumen of secretory units. We also found the myoepithelial cells around the secretory cells of glandular end pieces of vesicular gland in all bucks that helped in the excretion of vesicular secretion. All the bucks in the present study had only pars disseminata of prostate gland, and located in the propria-submucosa of the dorsal wall of the pelvic urethra. The secretory units and intraglandular ducts of the prostate gland were lined with simple cuboidal to columnar epithelium with basal cells. The bulbourethral glands were surrounded by the bulboglandular muscle, and the secretory units were lined with tall simple columnar epithelium and occasional basal cells. Most of the columnar cells were of the mucous type, with the nuclei basally placed and the cytoplasm contained the secretion granules in Black Bengal bucks

Carcinoma adenoide quístico de la glándula de Bartolino. Una entidad poco común sujeta a diagnósticos erróneos / Adenoid cystic carcinoma of Bartholin's gland—A rare entity likely to be misdiagnosed

Los carcinomas primarios de la glandula de Bartolino son muy infrecuentes. El carcinoma adenoide quístico, una variante de adenocarcinoma, es todavía más raro que otros tipos histológicos en este órgano. Este tumor maligno es localmente agresivo, ocurre en mujeres postmenopáusica y muy raramente se encuentra en mujeres menores de 40 años. Una mujer de 35 años consultó por dispareunia en el departamento ginecológico del ambulatorio de nuestro Instituto. La lesión había sido diagnosticada previamente como un proceso inflamatorio. El diagnosticó de carcinoma adenoide quístico fue realizado mediante punción aspiración con aguja fina y confirmado histopatológicamente. Comunicamos los rasgos citohistológicos de este raro tumor, diagnosticado en una paciente joven. Realizamos una revisión de la literatura pertinente(AU)

Primary carcinomas of Bartholin's gland are very rare. Adenoid cystic carcinoma, a variant of adenocarcinoma is even rarer than the other histological types at this site. This locally aggressive malignant neoplasm is usually found in postmenopausal females and occurs only very occasionally in women under forty years of age. A 35-year-old patient presenting with dyspareunia was admitted at our gynaecology outpatients department. The lesion had been previously misdiagnosed as an inflammatory lesion. The diagnosis of adenoid cystic carcinoma was made on fine needle aspiration cytology which was confirmed on histopathological examination. We report the cyto- and histopathological features of this rare tumour occurring in a young patient together with a review of the relevant literature(AU)

Changes in the histomorphology of the canine cervix through the oestrous cycle.

The importance of canine reproduction is steadily increasing and little is known about the canine cervix so far. The aim of this study was to describe the histomorphology of the canine cervix and to determine its correlation to the stage of oestrous cycle and to circulating concentrations of progesterone (P4) and estradiol-17beta (E2), respectively. Ovariohysterectomy (OHE) was performed in 33 non-pregnant, healthy, intact bitches in defined stages of oestrous cycle (proestrus N = 5, estrus N = 7, early diestrus N = 5, late diestrus N = 11, anestrus N = 5). The entire cervix was collected for histological evaluation of the epithelial layer (number of layers, thickness), the stroma (number of layers, thickness, density, structure, and distribution of elastic fibres) and the average area and density of cervical glands as well as blood vessels. These parameters were evaluated in all the three parts of the cervix (cranial, middle, and caudal or vaginal part). The cervix showed the typical structure with a superficial epithelium, a lamina propria with cervical glands and vascular structures and a tunica muscularis below. Folds in the superficial epithelium were only observed in 54% females (N = 18). Epithelial thickness (P < 0.0001), number of glands (P < 0.05), mean area of glands (P < 0.0001), mean area of venous vessels (P < 0.0001), number of arterial vessels (P = 0.02), number of mast cells and number of eosinophilic granulocytes per mm(2) (P < 0.01) were significantly influenced by the stage of cycle. The following factors were significantly influenced by the localisation: number of epithelial layers (P < 0.0001), thickness of stroma (P < 0.0001) and mean number of glands (P < 0.01). Only mean area of venous vessels was significantly influenced by the stage of cycle and the localisation (P < 0.01). Besides, P4 was significantly correlated to number of glands per mm(2) (P < 0.0001), mean area of venous vessels (P < 000.1) and number of mast cells (P < 0.01). This study provided detailed information about the histomorphological structure of the cervix in non-pregnant bitches and showed that the cervix undergoes cyclic changes during the canine oestrous cycle, in particular in association with circulating progesterone concentration.

Management of Bartholin's duct cyst and gland abscess.

Bartholin's duct cysts and gland abscesses are common problems in women of reproductive age. Bartholin's glands are located bilaterally at the posterior introitus and drain through ducts that empty into the vestibule at approximately the 4 o'clock and 8 o'clock positions. These normally pea-sized glands are palpable only if the duct becomes cystic or a gland abscess develops. The differential diagnosis includes cystic and solid lesions of the vulva, such as epidermal inclusion cyst, Skene's duct cyst, hidradenoma papilliferum, and lipoma. The goal of management is to preserve the gland and its function if possible. Office-based procedures include insertion of a Word catheter for a duct cyst or gland abscess, and marsupialization of a cyst; marsupialization should not be used to treat a gland abscess. Broad-spectrum antibiotic therapy is warranted only when cellulitis is present. Excisional biopsy is reserved for use in ruling out adenocarcinoma in menopausal or perimenopausal women with an irregular, nodular Bartholin's gland mass.

[Gaspard II Bartholin and the vulvovaginal gland]. / Gaspard II Bartholin et la glande vulvovaginale.

Born in 1655 in Copenhagen to a renowned family, Gaspard Bartholin had the good fortune during his stay in Paris to meet Joseph Guichard du Verney, a French anatomist who had discovered the glandula vestibuloris major. Back in Copenhagen he was appointed professor of anatomy at the age of 21 described the physiology of the glandula vestibuloris major, later known as Batholin's gland. Ennobled, laden with honours, he was later appointed personal physician to the king of Denmark until his death in 1738.

Based on histological studies of the prostate or Bartholin's gland, chemical analysis of the urine, injection site or implant was conducted in 114 veal calves suspected of receiving hormonal treatment. In 65% of the samples the results of chemical analysis confirmed the histological findings.

Pain during sex response due to occlusion of the Bartholin gland duct.

The greater vestibular glands produce a secretion during the plateau stage of sexual response. If the duct of the gland is partially or completely occluded, the secretion cannot be released and pain results from the pressure of the entrapped secretion. The pain is specific in its location and is elicited regardless of the mode of sexual stimulation. Four cases are presented in which duct occlusion appears to be the cause of pain during sex response. The gland was removed in 3 cases. In the fourth a marsupialization procedure was performed. The procedures were curative in all 4 cases. Relevant anatomy and sexual physiology are discussed.
