    Histological changes in benign solitary thyroid nodules – a prospective morphological studies

    Acta Endo (Buc) 2009 5(2): 221-231 doi: 10.4183/aeb.2009.221

    Abstract
    Background: The solitary benign thyroid nodules represent one of the most common\r\nabnormalities affecting the thyroid gland. The appearance of solitary thyroid nodules is\r\nvariable and all the patients should be assessed as soon as possible in order to establish the\r\nbenign nature of the lesion and to rule-out malignancy.\r\nThe aim of the present study is to show the histological changes that appear during\r\nevolution of benign solitary thyroid nodules and rapid growing rate along 6 years, in 71\r\npatients (65 women and 6 men).\r\nMethods: All cases were evaluated by clinical, ultrasound, biochemical (at every 6\r\nmonths) and FNA (initially and repeated between 10 months and 4 years afterwards); 26 out\r\nof 71 presented, along evolution, an increase of thyroid nodule (24 women and 2 men) from\r\n1.77 cm diameter (1.4-2 cm) to more than 2.5 cm (2.5-4.3 cm), therefore a radical surgical\r\nattitude was performed.\r\nResults: Histological postsurgery data showed degenerative changes in all cases, with\r\nrepetitive nodular hemorrhage (26 cases), sclerohyalinisation of the interfollicular stroma (4\r\ncases), cholesteatoma (5 cases) and inflammatory infiltrate (8 cases).\r\nIn conclusion, the significant growth of a benign solitary nodule is determined by\r\nrepetitive hemorrhages in the thyroid tissue. The associated sclerosis induces changes in the\r\nnodular firmness and might trigger the thyroid surgery.

    Menopausal Androgen Excess - Associated Cardio-Metabolic Risk: Clues for Ovarian Leydig Cell Tumour (Case Report and Mini-Review of Literature)

    Acta Endo (Buc) 2017 13(3): 356-363 doi: 10.4183/aeb.2017.356

    Abstract
    Background. Ovarian Leydig cell tumour is a very rare steroid hormones producing mass, causing clinical and biochemical hyperandrogenism. Even if the level of evidence is based on case studies, many authors (but not all) agree that raised androgens increase the cardio-metabolic risk thus early diagnosis and treatment are necessary On the other hand, the endocrine features pointing an ovarian tumour source of testosterone do not indicate the specific histological finding which needs a post-operative conformation. Case presentation. We report a case of a 60-yearold woman with a 4-year history of progressive virilisation in association with hypertension, high number of red blood cells, impaired glucose tolerance and dyslipidemia. Total testosterone was 20 times above normal with suppressed gonadotropins, inadequate for menopause. Trans-vaginal ultrasound and pelvic and abdominal computerized axial tomography imaging revealed a right ovarian solid nodule, and no evidence of alteration in the adrenal glands. Total hysterectomy and bilateral salpingo-oophorectomy were performed. Histopathology and immunohistochemistry confirmed the diagnosis of Leydig cell tumour. After surgery, androgen levels returned to normal and the doses of anti-hypertensive drugs were reduced. Conclusions. The hyperandrogenic state with elevated plasma testosterone and progressive signs of virilization raises suspicion of an ovarian androgen-secreting tumor. For a postmenopausal patient with hyperandrogenism the diagnosis of Leydig cell tumour should be considered. However, the exact diagnosis is provided by post-operative histological exam. Prolonged exposure to hyperandrogenism may generate cardiovascular abnormalities and metabolic syndrome which after tumor excision and removal of the source of androgen hormones are expected to significantly improve.
