Significance of peritoneal washing cytology in the accurate staging of malignant ovarian tumors.

Objectives: To identify the percentage of ovarian cancers with positive peritoneal cytology and to correlate the positive cytology with the prognostic factors.

Methods: This retrospective, cross-sectional study, evaluated the data of surgical specimens of malignant ovarian tumors, received in the Department of Pathology, Dow University of Health Sciences over a period of three years. The peritoneal cytology was correlated with these prognostic parameters: the size of the tumor, stage, capsular invasion, omental, and lymph node metastasis.

Congenital Orbital Teratoma with Unilateral Proptosis.

Teratoma is a rare tumor, containing structures originating from all three germinal layers. The most frequent location of teratoma is the gonads. Orbital teratoma is extremely rare.

Immunohistochemical Profile of Hodgkin and Non-Hodgkin Lymphoma.

Objective: To analyze the frequencies of histological types of lymphoma, diagnosed with complete immunohistochemical profile in younger and older age group.

Study Design: Cross-sectional analytical study.

Place And Duration Of Study: Dow Diagnostic Research and Reference Laboratory, Dow University of Health Sciences, Karachi, from January 2009 to September 2013.

INTRA OPERATIVE FROZEN EXAMINATION OF SENTINEL LYMPH NODE IN BREAST CANCER.

Background: Sentinel node (SN) biopsy is the standard of care for the assessment of axilla in early breast cancer patients with clinically node negative disease. Confirmed absence of tumour deposit in node on intra operative frozen section (FS) examination saves the patient from complete axillary dissection. However controversies arise when inconsistencies occur in results of frozen and permanent section.

Spectrum of malignancy in mixed tumors of salivary gland: a morphological and immunohistochemical review of 23 cases.

Malignancy arising in mixed tumors of the salivary gland is a distinct entity that can occur sporadically or in association with a background of pleomorphic adenoma. Carcinoma arising with a background of pleomorphic adenoma is well documented. However, there are rare occurrences of aggressive de novo carcinosarcomas of the parotid that have been reported.

Malignant adenomyoepithelioma of the breast: a case report with review of literature.

Adenomyoepitheliomas are uncommon breast tumours. By definition they have a prominent component of myoepithelial cells, in addition to glandular elements lined by epithelial cells. Malignant adenomyoepithelioma of the breast is even more rare, characterised by malignant proliferation of epithelial and myoepithelial cells that show characteristic histological and immunohistochemical features.
