Abstract	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.

Abstract	Karthik DhandapaniEwing sarcoma arises in both bones (most common) and soft tissues and it commonly affects young adults. The tumor is composed of small round cells showing positivity for CD99 and FLI1 on immunohistochemistry (IHC). We describe ganglion cell differentiation post-chemotherapy in Ewing sarcoma which is a rare phenomenon. A 13-year-old girl presented with a chest wall mass. On biopsy correlating with IHC, the diagnosis was rendered as Ewing sarcoma. She underwent neoadjuvant chemotherapy followed by resection of the tumor. On microscopic evaluation, the tumor showed prominent ganglionic differentiation with expression of neuronal markers. Although maturation post-chemotherapy is an established finding with better prognosis in other primitive pediatric tumors, such neural differentiation is rare with only a few case reports in Ewing sarcoma both post- and pre-chemotherapy. Clinical significance and prognosis of such differentiation which appear to be better are not yet established and needs to be elucidated.

Abstract	Spindle epithelial tumor with thymic like elements (SETTLE) is a biphasic tumor composed of epithelial and spindle cell components. It is an uncommon indolent tumor arising in the thyroid gland and most commonly affects the children and young adults. This entity is mostly overlooked because of its rarity and diagnostic difficulty on morphology. We discuss two cases of SETTLE with varied presentation, diagnostic challenges and lessons learnt from them.SETTLE should be considered as a differential especially when dealing with a thyroid lesion in young and adolescent. The article discusses the histologic details and common mimickers to be borne in mind aiding in arrival at the final diagnosis on biopsy specimens.

Abstract	Karthik DhandapanCystic hypersecretory carcinoma (CHC) is a rare subset of in-situ breast carcinoma with or without associated invasive carcinoma. It is part of a spectrum of cystic hypersecretory lesions that includes cystic hypersecretory hyperplasia (CHH), CHH with atypia, CHC in situ, and CHC with invasion. Only 20 cases of CHC with invasion have been reported so far. A 60-year-old female presented with a palpable right breast mass. A core needle biopsy was carried out, which was reported as invasive breast carcinoma with areas of ductal carcinoma in situ (DCIS). Modified radical mastectomy was done post-neo-adjuvant chemotherapy; On microscopy, dilated cystic spaces filled with eosinophilic secretions (thyroid colloid-like), lining neoplastic cells with variable degrees of proliferation and atypia were seen. There were multiple foci of invasion; both skin invasion and axillary lymph node metastasis were present. Immunohistochemistry (IHC) was done with relevant markers; correlating all these findings, a diagnosis of CHC with invasion was made. CHC is a distinct form of DCIS with or without associated invasion. Awareness of this entity is required to rule out other differential diagnoses and to avoid misinterpretation. Little is known about the IHC profile, biological behavior, prognosis, and molecular profile of CHC due to its rarity.

Abstract	Introduction: Neoadjuvant chemoradiation (CRT) is standard of care for locally advanced rectal cancer. However short course radiotherapy (SCRT) was developed for the benefit of a shorter treatment duration and early surgical intervention which also helped in reducing the case burden to the hospital. SCRT is routinely practised in European countries, Indian experience with the SCRT is limited and hence a pilot study was conducted to compare the morphological difference and pathological response between SCRT and CRT. Objectives: A) Evaluate the morphological changes and pathological response between SCRT and CRT. B) Compare the pathologic response with outcome between SCRT and CRT. Materials and methods: All rectal cancer patients in clinical stage II and III diagnosed during 2016 to 2020, who underwent SCRT or CRT were selected. Altered histopathologic findings due to therapy such as tumor cell morphology, necrosis and stromal response along with pathological response between the study groups were compared along with the outcome. Results: Ten (12.6%) patients were subjected to SCRT and 69 (87.4%) patients underwent CRT. Morphological changes such as necrosis was noted in nine (90%) and eight (11.5%) cases in SCRT and CRT group respectively. Pathologic complete response (pCR) was noted in 12 (17.5%) cases of CRT only. Near complete response was seen in one (10%) and 14 (20.5%) cases of SCRT and CRT respectively. Despite lower rates of pCR in SCRT, no difference in survival or outcome was noted between the two study groups. Conclusion: pCR as expected is less in patients who received SCRT, despite this the outcome during follow up was similar in both the groups. Indian data is very limited and large multi-centre studies should be carried as SCRT offers an advantage of early definitive surgical intervention in addition to shorter duration of hospitalisation when compared with CRT.

Abstract	Colorectal carcinoma (CRC) is the third most common cancer worldwide. Along with many established prognostic factors, tumor budding is emerging as a valuable marker of prognosis. Tumor budding is not yet universally reported but it has recently been suggested in guidelines by ITBCC (International Tumor Budding Consensus Conference). Our aim is to study prognostic implications of tumor budding in CRC. Hundred cases of primary CRC specimens were retrospectively studied from January, 2016, to February, 2017. Tumor bud count and other histopathological parameters were evaluated from hematoxyline and eosin (H & E) stained slides. Survival analysis was done using Cox proportional hazards model. Association of tumor budding and cancer-specific survival was found to be statistically significant (

Abstract	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.

Abstract	Neoadjuvant chemoradiation followed by surgery has been the standard of care for locally advanced carcinoma esophagus. We present our experience and inference of various factors associated with the same treatment and the prognostic influence of the same. A retrospective analysis of a cohort of 132 squamous cell carcinoma esophagus patients post neoadjuvant chemoradiation operated with curative intent was carried out. The 2-year overall survival rate was 64.5%. A pathological complete response was achieved in 32.5% of patients and was the only factor that significantly determined overall survival (
