Cellularity of lobular carcinoma and its relationship to false negative fine needle aspiration results.

Objective: To evaluate the cytocellularity and histocellularity of lobular carcinoma (LC) and the relationship to high false negative results of fine needle aspiration cytology (FNAC).

Study Design: In this retrospective study, cellularity was studied in 60 cases of classic LC, LC variants and lobular carcinoma in situ, comparing cytologic smears to their corresponding histologic sections. The cytologic smears were grouped into acellular, low, moderate and high categories, and the histologic sections were grouped into low, moderate and high categories.

Characterizing "blue blobs". Immunohistochemical staining and ultrastructural study.

Objective: To investigate the nature and origin of "blue blobs" (Bbs) in atrophic Pap smears in postmenopausal women and to study their clinical significance.

Study Design: A retrospective study of 412 atrophic Pap smears from postmenopausal women was done to detect the presence of Bbs. The smears from 24 cases showing Bbs were further studied to evaluate the nature of the Bbs with special stains, immunohistochemistry and electron microscopy.

Cytomorphologic features of classic and variant lobular carcinoma: A comparative study.

There are several subtypes of lobular carcinoma (LC), and their cytomorphologic features differ from classic lobular carcinoma (CLC). The finer details of the differences between CLC and variant lobular carcinoma (VLC) have not been adequately studied. A comparative study of 54 cases of CLC and VLC was done in order to verify any statistically significant differences between them.

Detection of Schistosoma mansoni in bronchoalveolar lavage fluid. A case report.

Background: Bronchoalveolar lavage (BAL) is a useful tool in the diagnosis of bacterial, viral, fungal and parasitic pulmonary infections. There have been rare reports of parasitic infestations in bronchoalveolar lavage fluid. This is the first case report on detecting a Schistosoma ova in BAL fluid.
