The use of high-frequency ultrasonography in the assessment of selected female reproductive structures: the vulva, vagina and cervix

ultrasonography (HFUS) of the vulva, vagina and cervix was performed. Equipment Two high-frequency scanners were used in the study: Episcan (Longport International, Ltd., USA) with a mechanical transducer of 50 MHz and DermaView (Dramiński S.A., Poland) with a mechanical transducer of 48 MHz. Due to the shape and structure of both transducers, the transducers from both of the Episcan and DermaView machines were used for vulvar examination, while vaginal structures and the cervix were evaluated using the

The utility of high-frequency ultrasonography in preoperative assessment of vulvar Paget’s disease – a case report

Introduction Paget’s disease of the vulva (PDV) is a rare superficial skin cancer accounting for less than 1% of all vulvar neoplasias(1). Extramammary manifestation occurs in the apocrine glands and is a form of intraepidermal adenocarcinoma(2,3). The most commonly affected regions are the vulva, perineum, perianal region, scrotum, penis, or pubic area(4). Although surgery is the most effective treatment, a complete excision is challenging due to PDV intraepithelial reticular spread(2

The usefulness of high-frequency ultrasonography in the evaluation of vulvar dermatoses in postmenopausal women – a preliminary report

Introduction The vulva is an external female genital organ, which has a complex anatomy composed of hymen, anal margin, labia minora, labia majora and clitorial hood(1). Different types of epithelium predispose to a wide range of conditions known as vulvar dermatoses(2,3). Vulvovaginal tissues are particularly susceptible to many irritants and allergens compared to other skin sites(4). Tissue atrophy and immunologic changes that occur with aging increase the risk of the most common vulvar

. All patients were over 70 years old. The main complain was pain and problems with urination (case 3) caused by urethral infiltration. First symptoms appeared approximately a year before in the form of a small red dot with itching. In gynecological examination, case 1 and 2 were solid tumors in the labia majora, with edema in the surrounding tissues. Palpation was difficult due to severe pain. Case 3 presented with massive edema of the vulva and a solid tumor infiltrating vagina and penetrating to

Some unique morphological and morphometric characters like the shape of lip region and amphidial fovea, the characters of the esophageal bulb (its small size and shape as well as the arrangement of glands nuclei) and the position of vulva delimiting the species well corroborated the identity of the species. However, new morphometric data ranges were recorded for the species as follows: the females and males of the presently studied

Moreover, they considered that Mesocriconema differs from Criconemoides (species with closed vulva and pseudolips not reduced). Geraert (2010) replaced some species in the genus Neobakernema (Ebsary, 1981b) by validation of this genus and listed

, spindle-shaped and scattered between the enlarged distal portion and the ovejector, with a lack of sperm in the genital tract. Ovejector is well developed (71–84 × 15–28 μm); vagina is perpendicular to body axis, 31–37 μm long or 42–52% of corresponding body diameter in lateral view and surrounded by robust muscles. Vulva, a transverse slit, pre-equatorial in position, is present. Pre-rectum variable is 503‒700 μm in length and the rectum length is 0.7‒1.1 times anal body diameter. A short tail

slightly narrow. Nerve rings usually surround the mid portion of the isthmus. Excretory pores are conspicuously located at the level of the basal bulb. The excretion duct is circularized and curved anteriorly, then posteriorly. Vulva near the mid body and lips protruding. Male: Similar to the female in general morphology except for a smaller size of 720 to 910 µm in length. The body is straight after fixation. Spicules are paired, separate, symmetrical, and slightly curved ventrally with hooked tips

Bursaphelenchus yongensis Gu, Braasch, Burgermeister, Brandstetter & Zhang, 2006 (Gu et al., 2006) was originally described from Pinus massoniana Lamb. in Ningbo city, Zhejiang province, China. It is characterized by a relatively slim body (a = 42 and 57 for females and males, respectively), excretory pore located at level of median bulb, lateral field with three lines, small vulval flap present, long post-uterine branch extending 2/3 to 3/4 of the vulva to anus distance and a conoid female

Intraspecific variation in phenotypic and phylogenetic features among Pratylenchus penetrans isolates from Wisconsin, USA

multiple species keys for the genus Pratylenchus (Loof, 1960; Corbett, 1970; Handoo and Golden, 1989; Ryss, 2002; Castillo and Vovlas, 2007). Consensus morphological characters are three lip annuli, round spermatheca, presence of males, smooth tail tip, and four incisures in the lateral field. Morphological measurements and indices of morphological features are also important, particularly the proportional position of the vulva (V%) and relative length of the esophagus and tail.

Morphological and molecular analyses of females (Fig. 2A-C) identified the species as Paratrichodorus minor (Colbran) Siddiqi; (Decraemer, 1995). Nematode body shape was “cigar-shaped” with dorsally curved “onchiostyle” stylet Females had an oval-shaped vagina, vulva a transverse slit, and lateral body pores were absent. The measurements
