Publication Leiomyosarcoma of the Inferior Venacava: A Case Report(Nepal Medical Association, 2019) Karki, Diksha; Upadhyaya, Paricha; Adhikari, Purbesh; Dahal, Mona; Thapa, Bishow Prakash Jung; Mudbhari, Bandana; Lama, Gopal; Pathak, NeeraAbstract Leiomyosarcoma of inferior venacava is a rare tumor. Female are most commonly affected and middle segment of inferior vena cava is the commonest site. The diagnosis can sometimes be challenging as patients present with non-specific symptoms. We present a case of a 65-year-old female who presented with pain in hypochondrium and epigastric region since 4 months along with weight loss, anorexia and vomiting. Histopathological examination revealed a capsulated, multilobated tumor arising from muscle layer of inferior venacava with extraluminal growth pattern and tumor cells showing cytoplasmic positivity for immuno-histochemical stain smooth muscle actin. With the diagnosis of leiomyosarcoma of inferior venacava, excision of tumor was done with tangential excision of 4 cm length of inferior venacava with primary repair.

As micronuclei score increases with malignancy, it can be an effective and inexpensive adjunct to breast fine needle aspiration cytology, in diagnosing breast lumps, especially detecting grey lesions between benign and malignant tumours. The aim of this study is to find out the mean micronuclei score in fine-needle aspiration cytology of patients with malignant breast lumps in the Department of Pathology in a tertiary care centre. Methods: A descriptive cross-sectional study was conducted among patients with malignant breast lumps in the Department of Pathology in a tertiary care centre between 1 May 2020 to 31 May 2021 after receiving ethical approval from the Institutional Review Committee (Reference number: IRC/2139/021). The fine-needle aspiration cytology of breast lumps was diagnosed as per National Health services breast screening program guidelines. The mean micronuclei score was calculated. Convenience sampling was done and data were collected from the hospital records in the Department. Point estimate and 95% Confidence Interval were calculated. Results: Among 20 malignant breast aspirates, the mean micronuclei score was found to be 8.30±3.75 (3-19, 95% Confidence Interval). Conclusions: The mean micronuclei score in fine-needle aspiration cytology of malignant breast lumps was found to be similar when compared to similar studies conducted in similar settings.
