Background: Malignant lymphomas (ML) are often complicated by serous effusions.The present study is an attempt to cytologically assess a large series of serous effusions associated with ML, identify the immunoreactivity of cells and to evaluate the role of various ancillary methods in confirming and subtyping these cases. Methods: A cross-sectional study of 4612 serous effusions was undertaken at the Department of Cytology, Gujarat Cancer and Research Institute by retrieving data from the year 2015 to 2017. Total 169 cases of ML, clinically suspicious, were included. All cerebrospinal fluids, serous effusions involved by myeloid neoplasms, and cases of primary effusion lymphomas were excluded from our study. Pap stained smears of all these serous effusions were examined. Ancillary methods such as immunohistochemistry were used to further subtype the positive cases using the WHO classification of hematopoietic and lymphoid neoplasms (2016). Results: Out of total 169 clinically suspicious cases, 109 cases were cytologically positive for ML which included 73 (66.9%) pleural effusions, 34 (31.1%) ascitic fluids, and 2 (1.8%) pericardial effusions. T-lymphoblastic lymphoma (36.9%) and Burkitt's lymphoma (38.2%) were the most common ML involving the pleural and ascitic fluids respectively. Non-Hodgkin's lymphoma (NHL) more frequently involved the serous cavities than Hodgkin's lymphoma. (P value <.0001). Among the NHL, T-cell lymphomas more commonly lead to serous effusions than B-cell lymphomas (P value <.0048). Conclusion: Cytological examination of serous effusions is an accurate, prompt, affordable technique having diagnostic and therapeutic implications. With the help of ancillary methods, we can identify the phenotype of cells, classify as well as confirm our diagnosis. K E Y W O R D S immunohistochemistry, malignant lymphomas, serous effusions

FNAC plays an important role in the diagnosis of lymph node metastasis in cases of STS.

Primary non-Hodgkin lymphoma of the liver is a very rare malignancy. In this case report, we describe a case of primary hepatic lymphoma (PHL) in a 60-year-old man who presented with lump and pain in the abdomen of 2 months’ duration. The patient had altered liver function, normal serum alfa fetoprotein level (AFP), normal hemogram and bone marrow. A computed tomography scan of the abdomen and pelvis showed an ill-defined hypodense mass with specks of calcification involving the liver, suggestive of primary malignant mass of liver. Diagnosis of PHL was established on the cytology smear and confirmed by immunohistochemistry on tissue biopsy. This case demonstrates that PHL should be considered in the differential diagnosis of space-occupying liver lesions in the presence of a normal level of AFP. Fine needle aspiration cytology is a faster and safer diagnostic modality even in such a rare case. The case has many unique features like negative serology for viruses, no type B symptom and normal lactate dehydrogenase level.

Metastasization and distinction from mammary carcinoma is of great clinical importance because of different treatment modalities. Here, we discuss a case of stage IIIC ovarian serous carcinoma, presenting with bilateral axillary nodes metastasis after 25 months interval of its initial presentation. Increased serum CA-125 level caused clinical suspicion. Computed tomography scan of abdomen and pelvis showed no residual disease or any abdominal lymphadenopathy. Mammography of both breast were normal. Bilateral axillary nodes were noted. Guided fine needle aspiration cytology (FNAC) and biopsy of ovarian carcinoma to axillary node is a rare event. Its recogn done. Cytomorphology revealed poorly differentiated carcinoma, compatible to that of primary ovarian tumor. Thus, metastatic carcinoma to axillary node from ovary was confirmed. This case illustrates a rare metastatic presentation of ovarian carcinoma and unequivocal role of FNAC to provide rapid diagnosis and preferred to be first line diagnostic procedure.

Background: Metastasis to the breast of an extra-mammary origin is very rare. FNAC plays an important role in differentiating non-mammary breast metastasis from primary malignancy. This study aimed to analyze the cytomorphological criteria and its pitfalls in differentiating metastatic lesion of the breast from primary malignancy. Methodology: Retrospective analysis of 891 FNACs of the breast was performed for a time span of 3 years. A total of 12 cases were diagnosed on FNAC as secondary neoplasms to the breast. Clinical and radiological data, along with Pap and MGG stained smears of each case were examined and correlated with the histopathology of the primary tumor. Statistical analysis was carried out. All cases of primary breast malignancies were excluded from our study. Results: In 10 out of 12 cases, primary malignancies were identified as Plasma cell myeloma (one case), B-acute lymphoblastic leukemia (two cases), acute myeloid leukemia (one case); chronic myeloid leukemia (one case), Burkitt's lymphoma of the ovary (one case), Diffuse large B-cell lymphoma (one case), esophageal squamous cell carcinoma (one case), spindle cell sarcoma (one case) and squamous cell carcinoma of the cervix (one case). The remaining two cases in our study were misdiagnosed on cytology as metastasis and turned out to be breast primaries on histopathology. Conclusion: Our case series highlights the importance of FNAC to differentiate secondary lesions from primary breast malignancy and thus helps to avoid unnecessary surgery to the patient. It emphasizes on the need to keep in mind the possibility of metastatic breast neoplasms in the presence of unusual cytological features on FNAC.

Background: Ovarian masses are frequent finding in females of reproductive age group. Image-guided fine-needle aspiration cytology (FNAC) of ovarian lumps is being increasingly used for the successful diagnosis of ovarian tumors, although borderline cases may be difficult to diagnose by this method. Objective: The present study was performed to evaluate the role of US-guided FNAC in pre-operative cytological diagnosis of ovarian masses in comparison with histopathology and to assess the pitfalls and limitations of cytological interpretation. Materials and Methods: The study was conducted on 160 female patients. Diagnosis was established by FNAC performed under image guidance (ultrasonography/computed tomography) followed by histopathological examination. Cytologic diagnoses were compared with the histopathological diagnosis. Results: On cytology and histopathology comparison, concordance was found to be 90.4% in case of malignancy, 94% in cases of suspicious for malignancy, 100% in cases of inflammatory lesions, 50% in cases of metastasis. Chi-square test was performed and p value was statistically significant (p < 0.0001). Conclusion: USG-guided FNAC seems to be a relatively safe, simple, fast and cost-effective procedure where most ovarian malignancies either present late in their course or no screening method is available. In addition this procedure may be useful in deciding management guidelines prior to any surgical intervention.
