Background: Phyllodes tumour is a rare breast neoplasm having three histological types i. e benign, borderline and malignant. Surgical excision is the mainstay of treatment, but quantification of adequate margin required during excision is still a matter of debate. Role of adjuvant radiotherapy also remains controversial. Aims: Study of prognostic factors in patients with phyllodes tumour of breast and their effect on survival. Setting and design: A retrospective analysis. Material and methods: From the year 2016 to 2019 we included 54 patients in this study and assessment of clinical and histopathological features, requirement of adjuvant radiotherapy and their effect on DFS (disease free survival) and OS (overall survival) was done. Log-rank test was used for univariate analysis and multivariate analysis was done by using Cox propotion hazard ratio method. Statistical analysis: Descriptive statistics was used for calculating proportion and median value. Survival analysis was done by using Kaplan Meier method. P value of

Abstract: Ossifying fibromyxoid tumor (OFMT) is a rare mesenchymal tumor of uncertain histogenesis with intermediate malignant potential presenting commonly in the fifth to sixth decade in the proximal limb and limb girdle. A 65-year-old male patient presented with a slow-growing gluteal mass. Wide local excision performed showed a well-defined tumor in the subcutaneous plane with a partially hard outer shell. Microscopy showed a moderately cellular tumor having cords and nests of round to ovoid cells with moderate cytoplasm and bland nuclei embedded in a myxo-hyaline matrix. An incomplete peripheral rim of ossification was seen. Pleomorphism/high cellularity was not seen. Mitosis was <2/50 high-power field. On immunohistochemistry, both S100 and desmin were positive. A diagnosis of typical OFMT was rendered. Even though rare with many morphological mimics, OFMT should be diagnosed with precision as most of these tumors are low-grade tumors that require only wide local excision and close follow-up without any adjuvant therapy., (Copyright © 2023 Copyright: © 2023 Indian Journal of Pathology and Microbiology.)

Background: Opinion remains divided as to whether excision of needle biopsy tract is beneficial and affect the prognosis. The aim of the study was to compare the outcomes in patients of primary malignant bone tumor who had undergone surgery with or without biopsy tract excision., Methods: From January 2017 to June 2020, 240 patients with primary malignant bone tumors who underwent percutaneous needle biopsy followed by surgery were included. We categorized patients into Biopsy tract excision (Group1:185 patients) and Non Biopsy tract excision (Group 2:55 patients). Median follow-up of patients was 58.6 months (range; 12-61.8months)., Results: Demographics, histopathological type, tumor location, type of surgery were similar in biopsy tract excision and non excision group. We found biopsy tract seeding in two cases out of 185 (1.1 %). Local recurrence in biopsy tract excision and non excision group was observed in 3.2 % and 1.8 % respectively with p value 0.58. The mean local recurrence free survival rate in group 1 and 2 was 60 and 44 months respectively. Limb salvage was performed in 71.6 % and in amputation in 28.3 % cases. The local recurrence in limb-salvage and amputation group was observed in 3.4 % (6/172) and 1.4 % (1/68) respectively., Conclusion: There was no significant difference in the rate of local recurrence between patients who were treated by biopsy tract excision or non tract excision. Percutenous needle bone biopsy tract leads to minimal risk of tumor seeding during surgical resection of primary bone tumors.We recommend the further multi centre studies with more number of patients to reach a consensus on resection of needle biopsy tract during surgical management of primary bone tumors., Competing Interests: NIL., (© 2023 Published by Elsevier B.V. on behalf of Professor P K Surendran Memorial Education Foundation.)
