Nowadays, adenomyosis represents one of the most common pathology of female genital system. It occurs at different ages, including nulliparous, infertile and multiparous women. The etiology of adenomyosis is still under investigation. Despite the fact that there are many different theories, none of them fully explain the mechanisms of adenomyoisis development. The pathogeneis of adenomyosis is also less studied. Many studies indicate the involvement of female sex hormone receptors, cell proliferation and apoptosis, as well as the involvement of inflammation. Some investigators describe the malignant transformation of adenomyosis, which makes the study of the disease etiology and pathogenesis more important. In current review, we discuss the different theories of adenomyosis development, as well as the risk of malignant transformation.

Crassolabium unicum sp. n., collected from a natural habitat in Vietnam, is described and illustrated. The new species is characterized by its 0.77–0.94 mm long body, three-layered cuticle, lip region offset by depression and 12–13.5 µm broad, odontostyle 13.5–15 µm long with wide aperture occupying 36–46% of its length, neck 235–260 µm long, pharyngeal expansion 117–131 µm long or occupying 47–52% of total neck length, anterior part of intestine presenting very distinct folds, female genital system didelphic-amphidelphic, uterus simple and 28–43 µm or 0.7–0.9 body diameters, vulva transverse (V = 45–52), prerectum bearing a blind postrectal sac, caudal region short and rounded (21–25 µm, c = 45–61, c’ = 0.6–0.8) with two (dorsal and ventral) lacunae between outer and intermediate cuticle layers, and male unknown. It is compared with the similar representatives of the genus.

Abstract The female genital system is rarely affected in von Recklinghausen neurofibromatosis. The vulva is the most frequent genital location, but vaginal, cervical, uterine, and ovarian neurofibromas have rarely been reported. We describe a case of plexiform neurofibroma affecting the uterine cervix in a patient with chronic pelvic pain and menorrhagia who had multiple cutaneous neurofibromas and 1 large paraspinal neurofibroma. A small plexiform neurofibroma, which was not grossly visible, was confined to the uterine cervix and coexisted with a uterine leiomyoma and adenomyosis. There were no neurofibromas in the myometrium, fallopian tubes, or ovaries. Plexiform neurofibroma is a neoplasm that should be considered in the differential diagnosis of spindle cell neoplasms of the uterine cervix, especially in specimens from patients with neurofibromatosis.

Abstract Three species of the genus Enchodelus, one new and two known, from natural areas in Romania are studied. Enchodelus carpaticus sp. n. is distinguished by its body 1.59-1.87 mm long, lip region offset by a marked depression and 17-20 μm diam., odontostyle 39.5-47 μm long and 2.1-2.5 lip region diam. or 2.3-2.8% of total body length, odontophore 42-51 μm long and with distinct basal flanges, neck 336-388 μm long, pharyngeal expansion 136-167 μm long or 39-45% of total neck length, presence of dorsal cell mass near cardia, female genital system amphidelphic, uterus tripartite and 144-195 μm long or 2.2-2.9 times the corresponding body diam., pars refringens vaginae with two trapezoidal sclerotisations, V = 42-50, and female tail short and rounded (21-29 μm long, c = 55-87, c′ = 0.5-0.7). Additional data, including LM pictures, are presented for E. macrodorus and E. saxifragae.
