A comparative analysis of mammography breast imaging reporting and data system score and fine needle aspiration cytology in the evaluation of palpable breast lump

Background: Breast lump is one of the commonest complaints with which patients present in breast clinics. As in most cases breast lump ultimately leads to a diagnosis of breast cancer, it is important for women with a breast lump to receive appropriate evaluation. So initial diagnostic approach such as utilization of rapid, inexpensive, presumptive and safe method is utmost important as such methods not only would benefit both patients and clinicians by prompting proper preoperative diagnosis and management but also further limits unnecessary testing and procedures. Aim and objectives of this study was to analyse the diagnostic accuracy of mammogram according to Breast Imaging Reporting and Data System (BI-RADS) score and fine-needle aspiration cytology (FNAC) in patients presented with benign and malignant breast lumps in authors centre.Methods: During this retrospective study from January 2018 to December 2018, the subjects concerned included all the female patients, who were referred to the department of pathology for FNAC of their breast mass and had radiological reports (mammography) with BI-RADS score according to the latest guidelines. The sensitivity, specificity, accuracy, positive and negative predictive values of BI-RADS scores and FNAC in diagnosis of breast diseases was done on the basis of final diagnosis.Results: In this study, the sensitivity, specificity, positive predictive value, negative predictive value and accuracy was 88.57%, 82.46%,75.61%,92.16% and 84.78%, respectively for Mammography (BIRADS) score and 100% for all the parameters on FNAC.Conclusions: According to authors above study findings concluded that FNAC could be considered an ideal initial diagnostic modality in all breast lumps recognized by means of imaging techniques. It is not only considered as safe, cost effective, rapid and presumptive diagnostic method but also further limits unnecessary testing and procedures.

Clinicopathological study of malignant melanoma in a regional cancer center

BACKGROUND: Malignant melanoma is a tumor of melanocytic origin. Although uncommon in India as compared with the west, its prevalence is increasing. OBJECTIVES: To document the pattern of clinicopathological features of malignant melanoma cases attending in a regional cancer center in eastern India. MATERIAL AND METHODS: The present study was a retrospective study of 182 cases diagnosed histopathologically as malignant melanoma during 2011–2016. RESULTS: Out of the total cases, 170 (93.4%) were cutaneous and 12 (6.6%) were noncutaneous melanoma. The most common age group was sixth decade with a male predominance. Conventional melanotic melanomas were 176 (96.70%), and only 6 cases (3.30%) were amelanotic melanoma. Among noncutaneous melanomas, 6 were in anorectum, 2 in conjunctiva, and 1 case each in nasal cavity, palate, gingivo-buccal sulcus, and vagina. The acrallentigenous type was the most common variety, and the mixed epithelioid and spindle cell type was the most common histopathological pattern. Clark's level III was the most common level of invasion. CONCLUSION: The lower extremity is the most common site for melanoma, whereas extracutaneous melanomas are exceedingly rare and aggressive neoplasms. Melanoma can metastasize to regional lymph nodes, however, visceral metastasis to liver can also occur. In the absence of pigment in amelanotic melanoma, immunohistochemical markers such as HMB 45 can be used for definitive diagnosis.

Hepatoblastoma--report of three cases.

Hepatoblastoma accounts for only 0.5% of all paediatric tumours. The vast majority of these cases are seen under five years of age and a third of patients have some form of congenital anomaly syndrome or other childhood tumour. Most recent classification describes six subtypes of hepatoblastoma. Surgical resection is the best treatment preceded by accurate staging and chemotherapy or radiotherapy. Hepatoblastoma can be diagnosed by Fine Needle Aspiration Cytology (FNAC). We report here three cases of hepatoblastoma diagnosed by FNAC and subsequently confirmed by histopathology following resection of hepatic tumours.

Squamous cell carcinoma of breast--report of two case.

Squamous cell carcinoma is an extremely rare variant of breast cancer. Presence of unequivocal squamous differentiation should be observed to diagnose a case as squamous cell carcinoma of breast since focal squamous metaplasia is frequently seen in common variants of breast carcinoma. We report here two cases of squamous cell carcinoma of breast, one a primary metaplastic type and the other one metastatic from a carcinoma of the cervix.

Proliferating Brenner tumour of ovary--a case report.

Transitional cell tumours or Brenner tumours of ovary are uncommon neoplasms. Out of all the Brenner tumours less than 2% are either proliferating or malignant type. Borderline or malignant tumours occur in women who are on an average 10 years older than those with benign tumours. It is essential to categorise these tumours as benign, borderline or malignant type as the biologic behaviour and choice of surgery differs in all of the three categories. The gross and microscopic findings of a proliferating brenner tumour are reported here.
