Sclerosing angiomatoid nodular transformation (SANT) of the spleen: review of the literature.

We present a sclerosing angiomatoid nodular transformation (SANT) case report in a 60 year-old-woman. SANT is an extremely rare benign disease of the spleen that it is radiologically similar to malignant tumors, and clinically difficult to differentiate from other splenic diseases. Splenectomy is both diagnostic and therapeutic in symptomatic cases. The analysis of the resected spleen is necessary to achieve the final diagnosis of SANT.

Dual staining for p16/Ki67 is a more specific test than cytology for triage of HPV-positive women.

Globally, cervical cancer (CC) screening is moving from cytology-based to HPV screening or a combination of both (co-testing). Most HPV-positive women clear the virus and do not develop relevant disease. Additional triage approaches are needed to reduce unnecessary colposcopy referrals. The p16/Ki67 dual stain cytology test (DSCT) is one of the most promising, but it has not (yet) been included as a recommendation in European guidelines. Previous studies in Spain on this issue are lacking. We studied the performance of p16/Ki67 DSCT for the triage of HPV-positive women in Navarra to detect precursor lesions (PLs) and CC compared to cytology only. We selected 1865 HPV-positive women with p16/Ki67 DSCT results and 304 women with an available biopsy result. Sensitivity, specificity and predictive values of the p16/Ki67 DSCT to detect underlying PLs and CC compared to cytology were calculated, using the biopsy as the gold standard. Cytology and p16/Ki67 DSCT showed similar sensitivity (99.0% vs. 98.0%), but cytology had significantly lower specificity (6.9 vs. 39.1%). Of the CIN2+/HPV+ women, triage using cytology only would have resulted in 40.2% true PLs and CC, while using p16/Ki67 DSCT this was 98.0% qualifying the women for colposcopy referral. Our results show that p16/Ki67 DSCT detects more than twice as many true PLs and CC than cytology only in this population. Thus, this test can be considered as an important additional tool in HPV testing-based screening strategies, to avoid unnecessary colposcopy referrals and to reduce health care costs.

[Influence of Age in the Prevalence of High-Risk Human Papiloma Virus in Women with Pre-Neoplasic Cervical Lesions in Navarra, Spain]. / Influencia de la edad en la prevalencia de virus de papiloma humano de alto riesgo en mujeres con lesiones precursoras de cáncer de cuello uterino en la Comunidad Navarra.

OBJECTIVE: Cervical carcinoma (CC) is the second cause of death among women aged 15 and 44 in Spain. CC is linked to hig-risk human papillomavirus (HR-HPV) infection and its prevalence varies according age and geographical region. The awereness of the latter is essential for public health prevention efforts. The aim was to study the age related in HR-HPV genotypes in cytologies with squamous intraepithelial lesion (SIL). METHODS: From a total of 67,935 ginecologic cytologies over a four-year period, we selected cytologic specimens with SIL. We used the Cervista® test to detect HR-HPV DNA. Women were classified into two groups under 35 and over 35 years old. Proportions were estimated with confidence intervals at 95% (95% CI). RESULTS: HR-HPV prevalence was 59,7%; 64,6% in women under 35 years old. HR-HPV species alpha 9 type 16 (HR-HPV 16) and alpha 5 type 51 (HR-HPV 51) were the most prevalent (60,9% and 51,7%). High-grade squamous intraepithelial lesions (H-SIL) were twice as high in women under 35 years (6,5 vs. 3,7%). 88,8% of H-SIL was associated HR-HPV 16, which increases the probability of H-SIL against Low-grade squamous intraepithelial lesions (L-SIL) regardless of age. CONCLUSIONS: In our population HR-HPV 16 was associated to H-SIL whereas HR-HPV specie alpha 7 type 18 and HR-HPV 51 to L-SIL regardless of age. The high prevalence of HR-HPV 51 in Navrra´s population (51,7%), suggests that local vaccination programs be re-assessed.

El cáncer de cuello uterino (CCU)es la segunda causa de muerte en España en mujeres entre 15 y 44 años. Esta ligado íntimamente a la infección por el virus del papiloma humano de alto riesgo (VPH-AR). La prevalencia del VPH-AR incrementa según la gravedad de la lesión, grupo etario y región geográfica cuyo conocimiento es esencial para el desarrollo de estrategias de prevención. El objetivo fue determinar la influencia de la edad de las mujeres (menores o mayores de 35 años) en relación con la especie de VPH-AR presente y la lesión escamosa intraepitelial (LEI).
