Idiopathic giant cell myocarditis--a case report and review of literature.

Idiopathic giant cell myocarditis (IGCM) is a rare clinicopathological entity which is usually known to cause in more than half the cases sudden death. The histological features are characteristic with a central area of myocardial necrosis and a rich cellular infiltration of lymphocytes with a few eosinophils, plasma cells, macrophages and multinucleated giant cells. We hereby report a case of IGCM in a 72 year old male with history of sudden death. This case is being presented for its rarity and a review of literature is made.

Fine needle aspiration cytology of head and neck masses.

Fine needle aspiration cytology (FNAC) was done on 150 patients with swelling in the head and neck region, during the period of 18 months from July 1994 to December 1995. Of these, 55 patients underwent surgery permitting a correlation between the histopathological diagnosis based on permanent paraffin sections and the diagnosis made by FNAC in order to evaluate FNAC in terms of accuracy along with its complications and limitations. The overall accuracy in the 55 cases evaluated was 92.73% with sensitivity of 90.91% and specificity of 93.18%. It was confirmed that FNAC is a highly diagnostic procedure for assessing swellings in the head and neck region. The method is simple, safe and economical.

Ovarian tumours: a study of 282 cases.

Histologically 282 ovarian tumours were studied, of these 212 (75.2%) were benign, 8 (2.8%) of borderline malignancy and 62 (21.9%) were malignant. The tumours were classified according to WHO classification. Epithelial tumours were the commonest variety constituting 70.9% of all the ovarian tumours followed by germ cell tumours (21.2%), sex cord stromal tumours (6.7%) and metastatic tumours (0.7%). Among the individual tumours, serous tumours (42.9%) were the commonest, followed by mucinous tumours (25.5%), teratomas (17%), granulosa cell tumours (6.7%), dysgerminomas (2.48%) and endodermal sinus tumours (1.77%). Two cases (0.7%) of endometrioid carcinomas and one case (0.35%) of clear cell carcinoma were encountered. Ovarian tumours were found to occur in the age range of 8 months to 74 years. Peak incidence was between 21 and 40 years age group.

Primary orbital NHL--a rare entity, diagnosed on FNAC.

Primary Orbital NHL is a rare, malignant neoplasm of the orbit. FNAC is particularly useful for patients with such non-resectable, deep seated retroorbital tumors which are difficult to biopsy and in whom a firm cytologic diagnosis is vital to guide further treatment, such as radiotherapy and chemotherapy. A case of 70 years old female is described in the present article.
