Remote supratentorial intraparenchymal bleed after posterior fossa surgery: A rare occurrence.

Background: Intraparenchymal hemorrhage at the operative site is one of the major complications of brain surgery. It is unusual to occur at a site remote from the operative site, but when it happens, it may cause significant morbidity and mortality. Case Description: We report the case of a 27-year-old male who presented with complaints of paresthesias over the left side of his face and decreased hearing from the left ear for two years. His radiology was suggestive of a large left cerebellopontine angle epidermoid cyst. The patient underwent left retro mastoid suboccipital craniotomy and near-total excision of the epidermoid cyst. The immediate postoperative non-contrast computed tomography scan of the brain was suggestive of no hematoma at the operated site but a remote left parafalcine frontoparietal intraparenchymal bleed, which was managed conservatively. At two months follow-up, he had no neuro deficits, and magnetic resonance imaging of the brain was suggestive of near-total excision of the epidermoid cyst with resolving left parafalcine frontoparietal bleed. Conclusion: We report this case due to the unique case observation of an intracranial bleed at a remote site rather than at the operated site.

Exploring Solitary Fibrous Tumors at a Tertiary Cancer Center: Clinicopathological and Immunomorphologic Profile.

Background Solitary fibrous tumor (SFT) is a distinct fibroblastic tumor that can occur at any anatomical site and can manifest a variety of histopathological features. NAB2-STAT6 gene fusion has recently emerged as a sensitive and specific molecular marker and its surrogate on immunohistochemistry, STAT6 has also displayed considerable efficacy. Nevertheless, its histologic diversity can result in diagnostic challenges, especially when classic features are not apparent. Methods A retrospective study was conducted at a tertiary cancer centre in North India over 3 years to document the clinicopathologic and immunomorphologic profile of SFTs. Immunohistochemical analysis of BCOR and p53 were gauged additionally and patients were stratified according to Modified Demicco and Salas criteria for risk of metastasis. Results Sixteen patients of SFT were identified, affecting middle-aged men and women equally. Though lung/pleura are known to be involved commonly, SFT affects other sites such as the kidney, brain, buccal mucosa, liver, and penis as well. The majority endured localized disease while a lesser number suffered locoregional/distant spread. Two patients revealed features of a malignant profile. Risk stratification according to the Modified Demicco and Salas criteria evinced comparable results. No discernible relationship however was highlighted between the immunohistochemical expression of BCOR, p53, and any significant SFT parameter. Conclusion Although SFTs are very rare substantially benign mesenchymal neoplasms, pathologists must be conversant with their histological diversity and be vigilant of their malignant attributes. The worth of STAT6 immunohistochemistry for precise diagnosis and long-term studies for delineating clinical behavior cannot be overemphasized.

Is FAST FORWARD the Way Forward in Radiotherapy for Locally Advanced Breast Cancer - Learnings From the COVID Pandemic.

INTRODUCTION: Low middle-income countries (LMICs), including India, have paucity of external beam radiotherapy (RT) machines leading to prolonged wait times for RT. Delay in delivery of RT has been shown to adversely affect outcomes in locally advanced breast cancer (LABC). With the availability of results of multiple randomized controlled trials, hypofractionated RT delivered over 3 to 4 weeks became the standard of care in breast cancer RT. METHODS: We conducted a retrospective audit of 172 LABC patients treated with ultrahypofractionated adjuvant RT (radiotherapy completed in 1 week) during the COVID pandemic. Log rank and Cox-regression model used for univariate and multi-variate analyses. RESULTS: No patient developed grade 3 esophagitis. Grade 2 esophagitis requiring short term narcotic analgesics was seen in 12 (6.9%) patients. Grade 2 or higher toxicity peaked between 2 and 3 weeks after RT. The estimated 2 and 3- year recurrence free survival (RFS) for the cohort is 87.1 % and 81.4 %, respectively. The estimated 2 and 3-year overall survival for the cohort is 95% and 91.3%. On multivariate analysis, presence of extra-nodal extension was found to be an independent factor associated with worse RFS (P = .028). CONCLUSIONS: FAST FORWARD protocol RT in LABC appears well tolerated.

Extended Use of McGregor Pedicled Groin Flap for Forearm: A Case Series.

Tissue loss in the forearm is a common entity. There are various etiologies to tissue loss like trauma, burn, post-surgery, etc. Coverage of defect or tissue loss of the forearm is a surgical challenge and options available for forearm coverage are limited. To bypass this difficulty, McGregor pedicled groin flap is used by us to cover large forearm defects with successful outcomes in this case series.

Surgical excision of a giant retroperitoneal liposarcoma with renal cell carcinoma: A case report of the largest retroperitoneal sarcoma.

INTRODUCTION: Retroperitoneal liposarcomas are rare malignant tumors known for their slow growth and challenging management, particularly due to their substantial size upon diagnosis. This case report highlights a remarkable instance of a massive retroperitoneal sarcoma concomitant with synchronous renal cell carcinoma. CASE PRESENTATION: We report a 57-year-old male patient with a huge abdominal mass hampering his daily activities and on further investigation, CECT abdomen and pelvis revealed a large Retroperitoneal Scarcoma (RPS) occupying his entire abdominal cavity displacing the visceral organs. In accordance with the final decision of the multi-disciplinary team meeting, he was subjected for surgery and the tumor was excised enbloc. He is kept under surveillance. DISCUSSION: Surgery remains the main modality of treatment for RPS. Hence careful preoperative surgical planning and execution with meticulous dissection aids in achieving a good clinical outcome and to reduce recurrence in future. CONCLUSION: Despite the huge size of the tumor, surgical intervention remains the primary treatment option whenever feasible, often complemented by additional therapeutic approaches.

Clinicopathologic Features of Metaplastic Breast Carcinoma: Experience From a Tertiary Cancer Center of North India.

Introduction Metaplastic breast cancer (MBC) is a rare malignancy that accounts for < 1% of all breast cancers. The aim of this study is to evaluate the clinicopathologic characteristics of MBC patients treated at a tertiary cancer center. Materials and methods In this study, the authors retrospectively analyzed the prospectively maintained data of MBC patients treated at a tertiary cancer care center in North India between January 2019 and July 2022. Results A total of 28 MBCs were identified. The median age of presentation was 47 years (range 27-81 years). Seventeen patients (60.7%) presented with clinical T3/T4 disease, and axillary nodal involvement was detected in 11 patients (39.3%) at presentation. Two patients had metastatic disease at presentation. A preoperative diagnosis of MBC on core biopsy was attained in five patients (17.9%), and the most common histologic subtype was sarcomatoid carcinoma. Triple-negative receptor status was observed in 15 patients (53.6%). Six patients (21.4%) underwent upfront breast conservation surgery and another six (21.4%) upfront mastectomy. Thirteen patients (46.4%) underwent mastectomy following neoadjuvant therapy. Definitive axillary nodal metastasis was found in eight patients (32%). Following neoadjuvant chemotherapy, five patients (35.7%) had stable disease, disease progression was evident in five patients (35.7%), partial response in four patients (28.6%), and no patient evinced complete response. Adjuvant postoperative radiation therapy was administered in 16 patients (57.1%). At a median follow-up of 13.2 months (range 4-26 months), 16 patients (57.1%) were alive with no evidence of disease, one patient (3.6%) was alive with disease, nine patients (32.1%) died of disease, and two patients (7.2%) died of other causes. One patient suffered from locoregional recurrence and nine patients developed distant metastasis. Conclusion MBC is an infrequent entity among breast carcinomas in India, which is similar to the reports of MBC worldwide. The diagnosis of MBC is difficult and requires the use of immunohistochemistry. Most of the cases in our study presented with a larger tumor size; however, they displayed a relatively lower incidence of nodal involvement as well as hormone receptor negativity. Being a rare and heterogeneous disease, large-scale studies are essential for better understanding and management of these tumors.

Pectoralis major myocutaneous flap in head and neck reconstruction: An experience in 100 consecutive cases.

BACKGROUND: The pectoralis major myocutaneous (PMMC) flap has been used as a versatile and reliable flap since its first description by Ariyan in 1979. In India head and neck cancer patients usually present in the advanced stage making PMMC flap a viable option for reconstruction. Although free flap using microvascular technique is the standard of care, its use is limited by the availability of expertise and resources in developing world. The aim of this study is to identify the outcomes associated with PMMC flap reconstruction. PATIENTS AND METHODS: After ethical approval we retrospectively analyzed 100 PMMC flap at a tertiary care hospital from 2006 to 2013. A total of 137 PMMC flap reconstructions were performed out of which follow-up data of 100 cases were available in our record. RESULTS: A total of 100 patients were reviewed of these 86% were of oral cavity and oropharyngeal lesions, 8% were of hypopharyngeal, 3% were of laryngeal malignancies and 3 cases were of salivary gland tumor. Most tumors (83%) were advanced (T3 or T4 lesion). 95 PMMC flap reconstruction were done as a primary procedure, and 5 were salvage procedure. PMMC flap was used to cover mucosal defect in 84 patients, skin defects in 10 patient and both in 6 patients. Overall flap related complications were 40% with a major complication in 10% and minor complications in 30%. No total flap loss occurred in any patient, major flap occurred in 6% and minor flap loss in 12%. In minor flap loss patients, necrotic changes were mostly limited to skin. Orocutaneous and pharyngocutaneous fistula developed in 12 patients. 10% patients required re-surgery after developing various flap related complications Pleural empyema developed in 3 patients. Other minor complications such as neck skin dehiscence and intra-oral flap dehiscence developed in 26 patients. CONCLUSION: PMMC flap is a versatile flap with an excellent reach to face oral cavity and neck region. With limited expertise and resources, it is still a workhorse flap in head and neck reconstruction.

Retroperitoneal lymphangioma in an adult: a case report of a rare clinical entity.

Background. Retroperitoneal lymphangioma is a rare, benign mesodermal tumor arising from the retroperitoneal lymphatics which usually presents in infancy and it is worthy to report a case when it has presented in an adult. After a thorough literature search in English we concluded that less than 200 cases of adult retroperitoneal lymphangioma have been reported so far. Apart from being a rare entity it also presents as a diagnostic dilemma and final diagnosis is often made on surgical exploration. Case Presentation. We report a case of retroperitoneal lymphangioma in a 55-year-old male who presented with abdominal distension and dull aching abdominal pain. Conclusion. Retroperitoneal lymphangiomas are rare tumors of infancy but may also present in adults where they are a diagnostic challenge. Differentiating cystic lymphangiomas from other cystic growths by imaging studies alone are often inconclusive and surgery is frequently required for definitive diagnosis and to ameliorate the symptoms.

Human papillomavirus 16 and 18 in squamous cell carcinoma of oral cavity and sexual practices: A pilot study at a Tertiary Care Hospital of North India.

CONTEXT: Oral squamous cell carcinoma (OSCC) is the most common malignancy in India and tobacco and betel nut chewing are well established risk factors. Despite successful campaigns to help people shun this habit in developing countries the incidence has rather gone up and HPV and sexual practices are now definitely implicated for this. AIM: An attempt was made to generate Indian data on role of HPV and sexual practices in relation to OSCC. SETTINGS AND DESIGN: A prospective observational study was conducted on 50 patients with oral squamous cell carcinoma. MATERIALS AND METHODS: Tissue biopsies from fifty patients of oral squamous cell carcinoma (OSCC) were subjected to PCR analysis to look for presence of HPV 16 and 18. Fifty patients with benign lesions were taken as control. STATISTICAL METHODS USED: The data was statistically analysed using SPSS version 22 and chi square test. RESULTS: 42% of OSCC patients were found to harbour HPV 16 and 18 whereas only 8% of patients with benign lesions had HPV 16 and 18. A significant number of HPV positive patients i.e. 9 out of 21 gave history of multiple sexual partners and oral sex. CONCLUSIONS: This high percentage of HPV in OSCC in an Indian population from a tertiary care centre in north India and its association with prevailing sexual practices is quite significant.

Effect of preoperative vitamin D deficiency on postoperative hypocalcemia after thyroid surgery.

BACKGROUND: Transient post thyroidectomy hypocalcemia occurs in up to 30% of patients. We evaluated the effect of vitamin D deficiency on post thyroidectomy hypocalcaemia. METHODS: This is a prospective study which was conducted from November 2010 to January 2013 and a total of 35 patients were included and data was analyzed regarding the relation between preoperative vitamin D3 levels and occurrence of post- thyroidectomy hypocalcemia. Patients were divided into two groups dependent upon the preoperative serum vitamin D level: group 1 with vitamin D levels <20 ng/ml and group 2 with serum vitamin D levels ≥20 ng/ml. Hypocalcemia was defined as a postoperative calcium level <8.5 mg/dl. RESULTS: There was a difference in postoperative hypocalcemia between the two vitamin D groups. In patients with serum vitamin D ≤20 ng/ml mean pre-operative and post-operative serum calcium levels were 9.3 ± 0.5 and 8.4 ± 0.58 g dl (p < .001) whereas in patients with serum vitamin D levels >20 ng/ml mean pre-operative and post-operative serum calcium were 9.52 ± 0.64 and 8.9 ± 0.5 (p = ns). CONCLUSIONS: Pre-operative serum vitamin D levels have got positive correlation with serum calcium levels in early post-operative period. Patients with serum vitamin D levels <20 ng/ml are highly likely to develop early post-operative hypocalcaemia and the difference between pre-operative and post-operative serum calcium levels in vitamin D deficient patients was significant (p < 0.001).
