Malignant fibrous histiocytoma metastatic to adrenal gland: a case report.

We report on a rare case of a 63-year-old male with malignant fibrous histiocytoma (MFH) metastatic to the right adrenal gland, first diagnosed with fine needle aspiration (FNA) biopsy. The cytological and immunocytochemical study indicated a malignant neoplasm of mesenchymal origin with characteristics of MFH. The patient was then operated on and the pathological and immunohistochemical findings confirmed the cytological diagnosis.

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.

Mediastinum thymoma diagnosed by FNA and ThinPrep technique: a case report.

Thymoma is a primary tumor of the thymus epithelial cells. It may be asymptomatic or accompanied with atypical clinical symptoms or paraneoplastic syndromes, such as myasthenia gravis. The biological behavior of thymomas is unpredictable.

Mammographic changes during postmenopausal hormonal replacement therapy with tibolone.

Purpose Of Investigation: To evaluate mammographic changes in postmenopausal women receiving hormonal replacement therapy (HRT) with tibolone.

Methods: 83 postmenopausal women aged 45-62 received the same dose of tibolone for a period of six months to five years without interruption. The women were examined mammographically every six to 12 months during the observation period.

Sonolysis of natural phenolic compounds in aqueous solutions: degradation pathways and biodegradability.

The sonochemical degradation in water of p-coumaric acid and p-hydroxybenzaldehyde, compounds that are commonly found in effluents of agricultural origin, was investigated using an 80 kHz horn-type sonicator. Experiments were performed at initial concentrations varying between 10 and 100 mg L(-1), an applied power varying between 75 and 150 W and liquid bulk temperatures varying between ambient and 70 degrees C. At the conditions in question, substrate removal was found to increase with increasing power and decreasing initial concentration and temperature.
