[Rupture of umbilical cord chorioangioma, intraamniotic hemorrhage and fetal death: report of a case and review of the literature]. / Rotura de corioangioma de cordón umbilical, hemorragia intraamniótica y muerte fetal: reporte de un caso y revisión de la bibliografía.

The umbilical cord is exposed to a great variety of injuries and events throughout the pregnancy whose origin may be either structural, mechanical, hamartomatous or infectious (1). Some of these alterations unquestionably interfere directly with the fetoplacental circulation either blocking it or creating severe haemorrhage as a result of laceration or tumor rupture. True tumors of the umbilical cord interfere directly with the fetal development. Two true tumors of the umbilical cord are described in this paper: chorangioma and teratoma. Chorangioma is a benign tumor, but has a very high rate of rate of perinatal mortality. Its frequency is rare, reporting in literature it presence of 1:3500 pregnancies. Our objective was to review world-wide literature and to report a case of fetal death by chorangioma of umbilical cord.

[Vaginal adenosis and vaginal intraepithelial neoplasia: a review of the literature and a case report]. / Adenosis vaginal y neoplasia intraepitelial de vagina: revisión de la bibliografia y reporte de un caso.

Vaginal adenosis is an uncommon pathology, characterized by the presence of cylindrical epithelium in the vagina. This pathology is considered rare if not found in women exposed in utero to diethylstilbestrol (dietilestilbestrol). Vaginal intraepithelial neoplasia (VAIN) is another uncommon condition in women who have not been hysterectomized to treat cervical intraepithelial neoplasia (CIN), with an incidence of 0.3 per 100,000 women. On the other hand 0.9% of the patients who have been poshysterectomized to treat CIN develop VAIN. This paper aims at reviewing the literature on vaginal adenosis, vaginal intraepithelial neoplasia and their possible treatments. In addition, the paper reports on a case of vaginal adenosis in a young female patient with concomitant VAIN 2, the CO2 laser ablation performed, and the short-term results obtained.

Diagnóstico y tratamiento de un papiloma solitario de lengua. Reporte de caso y revisión de la literatura / Diagnosis and treatment of solitary tongue papilloma. Case report and literature review

Los virus del papiloma humano (VPH) constituyen un grupo viral heterogéneo, cuyo genoma está constituido por ADN de doble cadena helicoidal con una cápside proteica. Existen más de 230 tipos de VPH (118 de ellos bien tipificados), más de 40 tipos anogenitales, de los cuales 15 son oncogénicos y, en humanos, constituyen unos de los grupos virales que con mayor frecuencia infecta el epitelio de piel y mucosas: conjuntivas, cavidad bucal, laringe y árbol bronquial entre otros. El papiloma escamoso de la mucosa oral, ocasionado por los genotipos 33 y 32, es la lesión papilar más frecuente y constituye el 2.5% de todas las lesiones de la cavidad oral, laringe, árbol bronquial, esófago, vejiga, ano y tracto genital. El objetivo del presente estudio es realizar una revisión de la literatura sobre la papilomatosis oral y reportar un caso.

Human papilloma viruses constitute a heterogeneous viral group; their genome is made up of a helicoidal double-stranded DNA molecule with a protein capsid. There are over 230 HPV types (118 of them well characterized; more than 40 are anal-genital types, out of which 15 are oncogenic). In humans they represent one of the viral groups which more frequently infect epithelium of skin and mucosae, conjunctive tissue, oral cavity, larynx, and bronchial tree among others. Oral mucosa squamous papilloma, caused by genotypes 33 and 32, is the most frequently found papillary lesion and represents 2.5% of all lesions of the oral cavity, larynx, bronchial tree, esophagus, bladder anus and genital tract. The aim of the present study was to conduct a literature review on oral papillomatosis as well as to review a clinical case.
