Synchronous adenocarcinoma and echinococcosis in the same ovary: a rare clinical entity.

BACKGROUND: Serous adenocarcinoma is the most common subtype of ovarian carcinoma, while ovarian echinococcosis is a rare disease of the female genital system. The simultaneous presence of adenocarcinoma and echinococcosis in the same ovary is extremely rare and little data exist regarding diagnosis and treatment approach. MATERIALS AND METHODS: In the present paper, we report a rare case of a 66-year-old Greek Caucasian woman of rural origin, with an adnexal mass, ascitic and pleural fluid. The patient underwent exploratory laparotomy following neoadjuvant chemotherapy, based on positive for malignancy pleural and ascitic fluid cytology results. RESULTS: Histological examination of the surgical specimen indicated the synchronous presence of echinococcosis and adenocarcinoma in the same ovary. CONCLUSIONS: Ovarian hydatid cyst is extremely rare, but should be suspected in patients with echinococcosis in other organs and those coming from endemic areas. Moreover, the disease could mimic ovarian cancer, as there are no specific symptoms and clinical signs. The coexistence of these two diseases in the same ovary, although rare, is possible. It seems that the presence of the hydatid cyst does not change the treatment approach of the malignancy so that surgery with neoadjuvant or adjuvant chemotherapy, according to the present guidelines, should be administered.

Selenomethionine treatment in patients with autoimmune thyroiditis: a prospective, quasi-randomised trial.

AIMS: To test whether selenium administration affects autoantibodies to thyroid peroxidase (anti-TPO) and thyroglobulin (anti-TG) titres in chronic autoimmune (Hashimoto's - HT) thyroiditis. METHODS: A prospective, open-label, quasi-randomised study in 86 HT patients (n = 86) assigned to either selenomethionine (Seme) 200µg daily for 3 months (Se3, n = 15) or 6 months (Se6, n = 46) or placebo (Control, n = 25). Serum Se, anti-TPO, anti-TG and thyroid hormones were measured in all patients at baseline, 3 and 6 months. A subgroup of 18 patients (twelve on Se6 and six controls) were subjected in thyroid fine-needle biopsy at baseline and 6 months to detect changes in lymphocyte infiltration. RESULTS: No significant difference in anti-TPO levels was recorded after 3 (p = 0.88) or 6 months (p = 0.62) on Seme. Anti-TG levels decreased both at 3 months (p = 0.001) and 6 months (p = 0.001). No significant changes in thyroid stimulating hormone, free thyroxine and free triiodothyronine levels or in the lymphocytes' number in thyroid cytology specimens were detected. Age, gender, duration of disease, baseline anti-TPO levels and per cent change in Se levels could not predict the response of anti-TPO levels to Seme administration. CONCLUSION: Our data suggest that Seme administration in pharmacological doses for a period of 6 months seems to have no significant effect on serum thyroid auto-antibodies' levels or lymphocyte infiltration of the thyroid gland.

Comparing normal primary endocervical adenoepithelial cells to uninfected and influenza B virus infected human cervical adenocarcinoma HeLa cells.

Human adenocarcinoma HeLa cells surviving infection with low (10(-9) units), medium (10(-6) units), and high (10(-2) units) influenza B titers were compared to their uninfected precursors and to normal endocervical adenoepithelial and metaplastic cells using Papanikolaou-staining method and immunocytochemistry. Normal primary endocervical and infected HeLa cells surviving infection shared similar morphologic, phenotypic, and divisional patterns that differed drastically from those of uninfected HeLa cells. The number of infected hosts surviving 6-7 days of viral exposure did not change during 3-week follow-up period, and their cyclin E levels suggested that they had been arrested to the G1 phase of the cell cycle by viral stress. Our findings suggest that in addition to apoptosis, nononcogenic viral stress activated the expression of endocervical metaplastic-like motifs in surviving hosts. A mechanism of cell response to nononcogenic viral stress was proposed to explain these findings. We conclude that nononcogenic respiratory viruses specifically target and eliminate abnormal cells ectopically overexpressing appropriate receptors and may complement current treatments of cervical cancer.

Basaloid squamous cell carcinoma of the uterine cervix with an uncommon metastasis to the left iliac region--case report.

We describe a rare and interesting case of a basaloid squamous cell carcinoma (BSC) of the uterine cervix with metastasis in the left iliac region diagnosed by fine needle aspiration (FNA). A 54-year-old woman underwent FNA because of a mass in the left iliac region. The material was processed by conventional liquid based cytology (ThinPrep), and by the cell-block technique and diagnosis was based on the cytomorphologic and immunochemical characteristics as well as the patient's history. The cytologic diagnosis concerned a poorly differentiated squamous cell carcinoma. After a laborious search, we found out that the patient had undergone a total hysterectomy almost 15 years before. The histological diagnosis then was an "infiltrative squamous cell carcinoma of basaloid type" of the uterine cervix. Our case is of particular interest because it is a rare type of neoplasm with an unusual site of metastasis after a long disease-free period.
