RESUMEN
In cytologic evaluation of body cavity effusions, the morphologic changes exhibited by reactive mesothelial cells often confound the diagnosis. This study investigates the role of DNA flow cytometry (DNA FCM) and image morphometry (IM) in improving diagnostic accuracy.
RESUMEN
A 58-year-old-man presented with painful rapidly progressive bilateral proptosis with restricted ocular movements of 15 days duration. There was history of significant weight loss in the recent past. Computed tomography scan of the head and orbit revealed bilateral multiple, well-defined, round, soft tissue masses, isointense with muscles in intraconal and extraconal space. Fine needle aspiration cytology and incision biopsy from the lesion, urine for Bence-Jones proteins and immunofixation clinched the diagnosis of multiple myeloma. Skeletal survey did not reveal any bony involvement.The diagnosis of multiple myeloma should be kept in mind in cases of bilateral proptosis. Bony involvement is not universal in cases of orbital myeloma. Early diagnosis can be established with extensive biochemical and histopathological investigations and timely treatment is life saving for these patients.

This study was undertaken to highlight the use of fine needle aspiration cytology (FNAC) to distinguish tumours metastatic to the breast from primary breast malignancies. A total of 1866 fine needle aspirates of the breast were performed during a period of 7 years. Three hundred and fourteen cases of breast malignancies were diagnosed and 5 (1.5%) out of these cases were metastatic in origin. The metastatic tumors included, 2 cases of malignant melanoma (chest wall and left arm), 1 case each of haematolymphoid malignancy, adenocarcinoma of the ovary, and squamous cell carcinoma (left leg). FNA diagnosis of metastasis to the breast is essential in order to avoid unnecessary mastectomy and to ensure appropriate chemotherapy and/or irradiation treatment.

Lymph node infarction is rare and can occur in either nonneoplastic or neoplastic conditions. Fine needle aspiration cytology (FNAC) of infarction preceding lymphoma has not been described earlier. A 26-year-old male, was referred to the cytology laboratory for FNAC of bilateral axillary lymph nodes. FNA smears showed uniform looking ghost cells. There were no viable cells. A biopsy was advised which also showed extensive coagulative necrosis. Five weeks later, right cervical lymph nodes also appeared and FNA smears showed discrete monomorphic population of immature lymphoid cells. A cytologic diagnosis of infarction in a case of non-Hodgkin's lymphoma (NHL) was made and subsequently confirmed by histopathologic examination. Our case indicates that such cases should be followed up closely and repeated aspirations should be done to prevent a delayed diagnosis of lymphoma.
