RESUMO
BACKGROUND: Strain echocardiography is a highly sensitive modality for detecting myocardial disease at an early stage. Therefore, we aim to evaluate subclinical left ventricular dysfunction in primary hyperparathyroidism (PHPT) patients with myocardial strain imaging in addition to conventional echocardiography and to look for its reversal after parathyroidectomy (PTx). METHODS: Thirty patients who underwent curative parathyroidectomy for PHPT were included. All patients were evaluated with M mode echo, 2D echo and strain imaging before and 6 months after PTx. Left ventricular ejection fraction, left ventricular diastolic dysfunction, left ventricular hypertrophy (LVH), Global Longitudinal Strain (GLS) and global circumferential strain (GCS) were recorded. RESULTS: On M mode echo, LVH was present in 15 patients and 8 of them improved completely after PTx (p < 0.038). Incidence of systolic and diastolic dysfunction on 2D echo was 10% and 13.3% respectively; while myocardial strain imaging showed impaired systolic function in 46.7% patients. Hence, compared to conventional 2D echo, strain imaging showed 36.7% high detection rate of subnormal cardiac function. There was improvement in left ventricle dysfunction (p = 0.083), GLS and GCS (p = 0.034) after PTx. Serum parathormone demonstrated a strong positive correlation with change in GLS and GCS (p = 0.013, p = 0.126) while serum calcium showed a weak correlation with change in GLS and GCS following surgery. CONCLUSION: Myocardial strain imaging should be considered for all PHPT patients as early identification of subclinical ventricle dysfunction provides an opportunity for an early intervention and thereby preventing development of irreversible LV dysfunction.

BACKGROUND: Postoperative nausea and vomiting (PONV) causes an unexpected prolonged hospital stay after ambulatory surgery. Novel measures such as preoperative loading of oral carbohydrates and postoperative chewing gum have recently gained momentum for postoperative recovery. This study evaluated the effects of preoperative carbohydrate loading and postoperative chewing gum (CG) on PONV after daycare laparoscopic cholecystectomy (LC). METHODS: A total of 100 patients were randomized to group A (preoperative carbohydrate loading with 200 ml of water with 25 g of carbohydrate and postoperative chewing gum (CG) when the patient responded to his/her name) and group B (standard care). The incidence of PONV and pain was assessed by using visual analogue scale. Quality of recovery (QoR-15) was assessed by using QoR15 questionnaire at 6 h, 24 h and 48 h after surgery. RESULTS: The incidence of PONV and pain was lower in group A; however, it was not significant (p > 0.05). The severity of PONV, pain and the need for rescue antiemetic was significantly lower in group A (p < 0.05). The episodes of PONV and required dose of antiemetic were less in group A. Group A also had a significantly higher QoR-15 score at all time points (p < 0.001). Preoperative dyspepsia was also noticed as a significant confounding predictor for postoperative vomiting. CONCLUSION: Preoperative carbohydrate drinks and early postoperative CG reduces the severity of PONV and requirement of antiemetics in patients undergoing LC. Hence, these simple measures can be used as a standard of care to optimize perioperative care in patients undergoing daycare surgery.

INTRODUCTION: Primary hyperparathyroidism (PHPT) in India is mostly symptomatic with renal and skeletal complications. Evidence on mortality outcomes following parathyroidectomy from India, where the disease is predominantly symptomatic is limited. MATERIAL AND METHODS: This was a prospective study to evaluate mortality outcomes in the Indian PHPT registry over the past 25 years (n = 464). Pre- and postoperative parameters and mortality data were obtained from medical records and/or by verbal autopsy, a method validated by WHO for data collection in settings where several deaths are noninstitutional. Patients were divided into survivor (SG) and nonsurvivor groups (NSG) to ascertain differences in presentation and the effect of parathyroidectomy. RESULTS: The overall mortality was 8.8% at a median follow-up of 8 years (IQR 1-13) after parathyroidectomy. Chronic kidney disease was the most common background cause of death (43.5%), followed by pancreatitis (28.2%). NSG had significantly more frequent renal dysfunction (91.9% vs 73.9%), anaemia (50 vs 16.6%) and pancreatitis (24.3 vs 6.4%). PTH (61.9 vs 38.3 pmol/l) and baseline creatinine (97.2 vs 70.7 µmol/l) were significantly higher and eGFR lower (66.7 vs 90.7 ml/min/1.73m2) in the NSG than SG. By Cox proportional modelling, renal dysfunction [HR 2.88 (1.42-5.84)], anaemia [HR 2.45 (1.11-5.42)] and pancreatitis [HR 2.65 (1.24-5.66)] on univariate and renal dysfunction [HR 3.33 (1.13-9.77)] on multivariate analysis were significant for mortality. Survival curves demonstrated a significantly higher mortality with lower eGFR values. CONCLUSIONS: Nonsurvivors in PHPT had greater prevalence and more severe baseline renal dysfunction than survivors. Survival after parathyroidectomy was significantly associated with estimated glomerular filtration rate at baseline.

BACKGROUND: Primary hyperparathyroidism (PHPT) is a systemic disorder characterized by hypercalcaemia and inappropriately elevated parathyroid hormone (PTH). Renal manifestations are one of the main presenting features both in symptomatic and asymptomatic PHPT patients. OBJECTIVES: We aimed to compare demographic, clinical and biochemical parameters of PHPT patients with and without renal manifestations and also analysed the influence of curative parathyroidectomy on renal functions. METHODS: We retrospectively analysed the data of PHPT patients from the last 25 years (1995- March 2019) and compared the demographic and clinical presentation and biochemical measurements between patients with and without renal manifestations and evaluated the changes in renal functions after 1 year of curative parathyroidectomy. RESULTS: Of the total 544 PHPT patients, 299 (55%) including 91 out of 141 (65%) males had renal manifestations. Among renal manifestations, nephrolithiasis and nephrocalcinosis were found in 41.7% and 27.6% PHPT patients, respectively. PHPT patients with renal manifestations had significantly higher creatinine (109.7 vs 79.6 µmol/L; P < .0001) and lower eGFR level (78.8 vs 93.9 mL/min/1.73 m2 ; P < .0001) compared to patients without renal manifestations. Parathyroidectomy resolved the clinical symptoms with biochemical cure in the patients from both the groups. Patients with renal manifestations showed improvement in creatinine and eGFR levels after 1 year of curative parathyroidectomy; however, patients without renal manifestations showed no change in creatinine and eGFR levels. CONCLUSION: Young age and male gender are predictors of renal manifestations in PHPT. Curative parathyroidectomy improves renal functions in PHPT patients with renal manifestations compared to PHPT patients without renal manifestation.

OBJECTIVE: To describe the details of widely invasive parathyroid carcinoma (WIPC) patients admitted in the Endocrinology department of our institute during the last 22 years and to compare their clinical, biochemical, and hormonal profile with minimally invasive parathyroid carcinoma (MIPC) and sporadic parathyroid adenoma patients. METHODS: This is a retrospective analysis of data from the Indian primary hyperparathyroidism registry. RESULTS: Of the 547 primary hyperparathyroidism patients in the registry, 5 (2 men and 3 women) had WIPC (0.9%) and 7 (1 man and 6 women) had MIPC (1.3%), with median ages of 45 (interquartile range, 41-51) years and 47 (interquartile range, 28-48) years, respectively. Among the patients with WIPC, renal manifestations were present in 5 patients, skeletal manifestations in 4 patients, and palpable neck masses in 4 patients. Three patients had distant metastases and 2 had cervical lymph node involvement. All 5 patients had surgical resection of their cancers, with persistent disease in 4 patients, but all patients died within 2 years after surgery. One patient with MIPC had a palpable parathyroid nodule; none had lymph nodal or distant metastases. None of the patients with MIPC died during the median follow-up of 18 (interquartile range, 12-18) months. Patients with WIPC had significantly higher serum calcium level compared with sporadic parathyroid adenoma patients with skeletal and renal manifestations. CONCLUSION: Accurate histopathologic classification of parathyroid carcinoma is important as WIPC is associated with a more aggressive clinical course and a higher risk of mortality than MIPC.

Duplication of the inferior vena cava is a rare congenital anomaly, with an incidence of 0.2-3%. Despite being asymptomatic, anomalies of IVC are important in aortoiliac and retroperitoneal surgeries. Preoperative CT imaging is essential to identify any IVC anomaly and to prevent unexpected hemorrhage during surgery. Here, we report a case of a juxtarenal abdominal aortic aneurysm in which we encountered a type I IVC duplication anomaly intraoperatively while performing transperitoneal aneurysmorrhaphy and took precautions to avoid any iatrogenic injuries to either of the two trunks or the pre-aortic trunk of the anomalous duplicate IVC.
A duplicação da veia cava inferior (VCI) é uma anomalia congênita rara com incidência de 0,2 a 3%. Apesar de assintomáticas, anomalias da VCI são importantes em cirurgias aortoilíacas e retroperitoneais. A imagem da tomografia pré-operatória é essencial para identificar qualquer anomalia de VCI e para evitar hemorragia inesperada durante a cirurgia. Relatamos um caso de aneurisma de aorta abdominal justarrenal, no qual encontramos uma anomalia de duplicação de VCI do tipo 1 intraoperatório enquanto realizávamos correção cirúrgica de aneurisma transperitoneal. Por isso, tomamos a precaução para evitar qualquer lesão iatrogênica nos dois troncos e no tronco pré-aórtico de VCI duplicada anômala.
RESUMO
PURPOSE: Nelson's syndrome (NS) is regarded as an aggressive complication of total bilateral adrenalectomy (TBA) for Cushing's disease (CD). This challenge may be addressed by using clinical criteria to guide frequency of neuroimaging to enable timely management of NS and also avoid unnecessary frequent imaging. METHODS: All patients (n = 43) with CD subjected to TBA over 35 years at a tertiary care centre were included. NS was defined as a newly appearing or expanding (> 2 mm) pituitary adenoma with or without ACTH levels exceeding 500 pg/ml. Pre-and post-TBA parameters like clinical symptomatology, cortisol, ACTH and radiology were analysed for the prediction of NS. RESULTS: NS developed in 39.5% (n = 17) patients with a median follow-up of 7 years. Half of them had new appearance, while rest had an expansion of pre-existing pituitary tumour. Majority (90%) had ACTH above 500 pg/ml. On Cox proportional hazards analysis, frequent discriminatory features of protein catabolism (≥ 4) (HR 1.15, CI 0.18, 7.06), proximal myopathy (HR 8.82, CI 1.12, 69.58) and annual ACTH increment of 113 pg/ml (HR 12.56, CI 1.88, 88.76) predicted NS. First post-operative year ACTH indices predicting NS included ACTH rise of 116 pg/ml and absolute ACTH of 142 pg/ml (sensitivity, specificity exceeding 90%). Annual ACTH increment exceeding 113 pg/ml, ≥ 4 discriminatory features and uncontrolled hypertension had the best overall prediction. CONCLUSION: Patients who developed NS had higher rebound rise of ACTH following TBA and a more severe disease phenotype at baseline. Consistent ACTH increment can be used as a marker for predicting the development of NS.

PURPOSE: Minimally invasive parathyroid carcinoma (MIPC) is clinically and biochemically comparable with parathyroid adenoma (PA) though histopathologically differ from PA. MIPC is an intermediate of PA and parathyroid carcinoma (PC). In literature, there is no definite criterion to diagnose MIPC. Our aim was to evaluate and characterize the imaging and biochemical parameters with histological characteristics of MIPC. METHODOLOGY: Ten patients with MIPC were recruited from (single centre) Indian PHPT registry (www.indianphptregistry.com) from January 2014 to July 2018. Clinical, biochemical, imaging and histological features of MIPC patients were reviewed. RESULTS: The mean age of MIPC patients (n = 10; 3 males) was 39.9 ± 11.3 years (range: 17-50). All patients had an elevated preoperative parathyroid hormone (iPTH) level ranging from 427 to 2138 pg/mL (median: 1328). MIBI scan showed intensely avid and enlarged parathyroid tumours in all patients; LIPT in 6, RIPT in 3 and ectopic mediastinal in 1 with mean size of the tumours was 2.8 ± 1.1 cm. The mean of maximum standardized uptake value (SUVmax) of MIPC in F-18 fluorocholine PET/CT was 6.7 ± 1.1 (range 6.0-8.3). The mean tumour weight was 12 ± 9.5 g (range: 1.09-28). All MIPC patients had identified capsular invasion in 80% and vascular invasion in 50% only but there was no local invasion, lymph nodal or distant metastasis. The mean Ki-67 labelling index was 3.2 ± 2.7 (range 1.1-10). CONCLUSION: The study concluded that MIPC patients are less aggressive (on the basis of imaging and histopathological findings) and should be differentiated from parathyroid adenoma and carcinoma.

OBJECTIVE: Primary hyperparathyroidism (PHPT) is relatively common among adults but rarely encountered in children and adolescents. According to the western literature, young PHPT is different from adult PHPT and is associated with more severe hypercalcemia. PHPT in the adult Indian population is different from its western counterpart. Here we present the clinical, biochemical, and surgical characteristics of young patients with PHPT treated at our tertiary care center. METHODS: PHPT patients were divided into adult (≥25 years) and young (<25 years) groups. The clinical, biochemical, hormonal, and histopathologic characteristics and treatment outcomes in the groups were compared. RESULTS: Out of 358 patients, 47 patients were young and 311 patients were adults. The mean ages of the groups were 19 ± 4 and 45 ± 12 years, respectively. The corresponding female-to-male ratios were 1.24:1 and 3.38:1 ( P<.05). The nature and frequency of presenting symptoms were comparable between the 2 groups. The most common symptom in young patients with PHPT was bone pain and was not significantly different from adults (57% vs. 61%, respectively). The most common symptom in adult PHPT was fatigue, which was also not significantly different from young patients (63% vs. 53%, respectively), The serum calcium, phosphate, 25-hydroxyvitamin D levels; alkaline phosphatase Z-score; and parathyroid hormone levels were comparable between the 2 groups. Parathyroid adenoma was the most common histopathologic finding, while hyperplasia was rare in both groups. CONCLUSION: We observed that young PHPT is not markedly different from its adult counterpart in an Indian population.

BACKGROUND & OBJECTIVES: The frequency and predictors of pancreatitis in primary hyperparathyroidism (PHPT) are not well understood. The objective of the present study was to evaluate the frequency of pancreatitis in patients with PHPT and its association with clinical and biochemical parameters of the disease. METHODS: In this retrospective study all consecutive patients with PHPT registered in the PHPT registry (www.indianphptregistry.com) from the year 2004 to 2013 were included. The clinical, biochemical and radiological parameters related to pancreatitis were evaluated in histologically proven PHPT patients. RESULTS: A total of 218 patients (63 men; mean age: 40.6±14.4 yr) underwent surgery for PHPT during the study. Pancreatitis occurred in 35 [16%, 18 acute and 17 chronic pancreatitis (CP)] patients and male:female ratio was 1:0.94. Skeletal manifestations were seen less frequently in PHPT with pancreatitis as compared to that of PHPT without pancreatitis. PHPT with pancreatitis had significantly higher serum calcium (12.4±2.0 vs. 11.7±1.5 mg/dl, P <0.05) in comparison to PHPT without pancreatitis. PHPT with acute pancreatitis (AP) had higher serum calcium (P <0.05) and parathyroid hormone (PTH) (P <0.05) levels than PHPT with CP. Curative parathyroidectomy improved the symptoms associated with pancreatitis as there was no recurrence in AP group, whereas recurrence was observed only in about 10 per cent patients of the CP group. INTERPRETATION & CONCLUSIONS: Pancreatitis was observed in 16 per cent of PHPT patients with male predominance in the study population. No recurrence of AP was observed after curative surgery. It may be proposed that serum amylase with calcium and PTH should be measured in all patients of PHPT with pain abdomen to rule out pancreatitis.

OBJECTIVE: Urolithiasis may be the only presenting manifestation of primary hyperparathyroidism (PHPT), and early detection of PHPT in such patients may prevent future urolithiasis and other PHPT complications. This study was performed to study the prevalence and predictors of PHPT in patients presenting with urolithiasis. METHODS: Consecutive patients presenting with urolithiasis were evaluated for clinical and biochemical manifestations of PHPT with serum and urine calcium (Ca), serum intact parathyroid hormone and 25 (OH) vitamin D. We then compared the clinical and biochemical characteristics of PHPT patients presenting with urolithiasis (group A) and without (group B). RESULTS: During the 3-year study period, 381 patients with urolithiasis were seen with a mean age of 38.5 ± 13.9 years. Nineteen of the 381 (5%) patients had histologically proven PHPT (group A). Four patients in group A (21%) and 8 in group B (2%) had nephrocalcinosis (P<.0001), multiple stones (≥3), calcific pancreatitis, and neuropsychiatric manifestations were more common in group A (P<.0001). Presence of multiple or bilateral stones, and recurrent stone episodes predicted PHPT (odds ratio [OR]: 3.06, confidence interval [CI]: 0.87, 0.7). CONCLUSION: One out of every 20 patients with urolithiasis had PHPT, which is higher than the prevalence of PHPT in general population. The presence of nephrocalcinosis and multiple, bilateral, and recurrent stone disease increased the risk of PHPT among stone formers. ABBREVIATIONS: Ca = calcium; CI = confidence interval; iPTH = intact parathyroid hormone; nPHPT = normocalcemic PHPT; OR = odds ratio; PHPT = primary hyperparathyroidism.

PURPOSE: The pathogenesis of parathyroid tumours is only partially understood. A direct approach using proteomics could be a promising tool to increase our understanding of parathyroid tumorigenesis. The aim of the study was to investigate differentially expressed proteins to explore the underlying molecular basis of the disease and identify potential target proteins responsible for the genesis of adenoma. METHODS: Proteins were extracted from adenomatous and normal parathyroid tissues. Differentially expressed proteins were separated by two-dimensional gel electrophoresis (2-D) and identified by matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry. Statistical analysis was performed using spss 10.01 software. RESULTS: Comparative analysis of the 2-D profiles of proteins isolated from adenomatous and normal parathyroid tissues showed 15 differentially expressed proteins, of which 11 were overexpressed. The characterized proteins were associated with diverse cellular functions including regulation of cell organization, programmed cell death, transcription and signal transduction. CONCLUSION: The differentially expressed proteins in parathyroid adenomas may potentially serve as new targets to investigate the mechanisms of parathyroid adenoma transformation.

Dermatofibrosarcoma protuberans (DFSP) is an aggressive tumour with multiple local recurrences and rare metastatic potential. Fibrosarcomatous transformation occurs in a few cases of DFSP which makes them more aggressive in terms of recurrence and metastasis. Here we report the case of a woman in her late 30s who presented with massive lower gastrointestinal (GI) bleeding with a history of multiple surgeries for DFSP on her anterior abdominal wall. The bleeding source was identified to be a mass lesion in the jejunum, which was excised. The patient recovered well and the histopathology revealed fibrosarcoma of the jejunum. Follow-up investigations showed multiple lung nodules, ascites and abdominal lymph nodes suggesting progressive disease. She is currently receiving chemotherapy and progressing well 3 months postoperatively. Patients with fibrosarcomatous changes within DFSP must be followed up closely as it is associated with increased metastatic potential.

INTRODUCTION: Extracranial carotid artery (CA) pseudoaneurysms are uncommon and can cause embolic stroke, compressive symptoms, or (rarely) can rupture. It is of paramount importance to treat this entity to avoid life-threatening complications. In this study, the authors described a cohort of patients that required open surgical repair. METHODS: This article reported the authors' experience with open surgical repair of extracranial CA pseudoaneurysms by presenting a retrospective review of data at their institution from 2016 to 2022. RESULTS: Of 8 patients that underwent open repair, 6 were male and 8 were female. The most common etiology was traumatic (penetrating trauma in 4 patients, iatrogenic injury in 2, and blunt trauma in 1) and 1 was infective. All patients presented with a neck mass, and 5 had compressive symptoms. Primary repair was performed in 4 patients, interposition graft using an autologous vein in 2, and patch repair in 2. None of the patients experienced perioperative mortality or stroke; nor did they develop any complications over a median follow-up period of 30 months. CONCLUSION: This report demonstrated that large-size extracranial pseudoaneurysms, whether traumatic or infective etiology, can be safely repaired using an open surgical approach.

Post-liver transplant (LT) hepatic artery vasospasm is a vascular complication that is not well recognized and its incidence is not known. As a possible sequela to vasospasm, hepatic artery thrombosis is the second major cause of allograft failure after primary nonfunction and its reported incidence is 2.9% in adults and 8.3% in pediatric LT. Lacuna in knowledge regarding early hepatic artery vasospasm post-LT makes it a difficult condition to diagnose and treat, as the initial ischemic insult on graft can have devastating consequences. We report a case of pediatric progressive familial intrahepatic cholestasis type 3-related chronic liver disease who underwent cadaveric orthotopic LT and postoperatively developed fever, worsening hypotension, and elevated liver enzymes with an absence of arterial flow in intrahepatic branches on Doppler ultrasound. Suspecting early hepatic artery thrombosis, the patient was re-explored and the graft hepatic artery was found to be in a state of vasospasm. Following the infusion of intra-arterial papaverine, urokinase, and intravenous nicorandil, there was an improvement in blood flow. The patient responded well and was discharged on postoperative day 23 with normal liver enzymes.
RESUMO
OBJECTIVE: Chronic venous disease (CVD) is accompanied by a spectrum of skin changes. The aim of this study was to assess skin changes in CVD in different classes of the classifications such as the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification using ultrasound (US). METHODS: This study was conducted from July 2020 to July 2021 after obtaining approval from Institutional Ethical Committee. Patients with chronic venous insufficiency were enrolled after taking informed consent. Assessment of cutaneous layer (CL), subcutaneous layer (SCL), dermo-hypodermal junction (D-HJ), and other significant US findings were noted. RESULTS: Ninety-eight limbs were evaluated. Most common skin finding was dermal edema in 59 (60.2%) legs. Other findings included infiltrates, CL thickening, hyper echogenicity and thickening of SCL, anechoic lacunae, disappearance of D-HJ, and epidermal loss or change in thickness of epidermis. Notably, US detected dermal edema in 15 and infiltrates in five C2 legs (normal on inspection). CONCLUSION: US evaluation of skin changes adds insight to clinical assessment and may reveal skin changes in legs affected with CVD that may appear normal on clinical examination.

Advanced and metastatic gastrointestinal stromal tumors (GISTs) presenting with surgical emergencies are rare. Neoadjuvant imatinib being the treatment of choice for non-metastatic advanced disease with a proven role in downstaging the disease may not be feasible in patients presenting with bleeding and obstruction. We present a case series with retrospective analysis of a prospectively maintained database of patients with advanced and metastatic GISTs presenting with surgical emergencies. Clinical characteristics, imaging and endoscopic findings, surgical procedures, histological findings, and outcomes in these patients were studied. Four patients were included in this case series, with three males and one female (age range: 24-60 years). Two patients presented with melena; one with hemodynamic instability despite multiple blood transfusions underwent urgent exploratory laparotomy for bleeding gastric GIST, while the other underwent surgical exploration after careful evaluation given the recurrent, metastatic disease with a stable metabolic response on six months of imatinib. One patient with metastatic jejunal GIST who presented with an umbilical nodule and intestinal obstruction was given a trial of non-operative management for 72 hours, but due to non-resolution of obstruction, segmental jejunal en bloc resection with the dome of the urinary bladder with reconstruction and metastasectomy was needed. The patient with advanced gastric GIST who presented with gastric outlet obstruction was resuscitated, and an attempt of endoscopic naso-jejunal tube placement was tried, which failed, and exploration was needed. The mean length of hospital stay was 7.5 days. Histopathological examination confirmed GIST in all four patients with microscopic negative resection margins. All patients were started on imatinib with dose escalation to 800 mg in the patient with recurrent and metastatic disease; however, the patient with bleeding gastric GIST experienced severe adverse effects of imatinib and discontinued the drug shortly. All four patients are disease-free on follow-ups of 15 months, 48 months for the patient with advanced non-metastatic disease, and six and 24 months for the patients with metastatic disease. In the era of tyrosine kinase inhibitor (TKI) therapy for advanced and metastatic disease, upfront surgery is usually reserved for surgical emergencies only. Surgical resection, the cornerstone for the treatment of resectable GIST, may also be clinically relevant in metastatic settings, although it requires a careful and individualized approach.
RESUMO
Introduction: Insulinomas are rare, usually sporadic, and typically benign pancreatic neuroendocrine tumours. Pre-operative localization is challenging and evidence on comparative analysis of anatomic and scintigraphic modalities for pre-operative tumour localization is limited, even in contemporary series. Methods: The current study was designed to study the clinical features and management challenges of insulinomas managed at a tertiary care centre. Clinical features, diagnosis, imaging techniques, surgical procedures, and outcomes details were collated. Pre-operative imaging techniques (CT/MRI, nuclear scintigraphy) were compared with intraoperative and histopathological findings to assess their accuracy of localization. Results: Thirty-seven patients (15 females [42%]; median age 36 years [IQR 28-49]) were included in the study. In four patients (10.8%), the tumour occurred in the setting of multiple endocrine neoplasia type 1 (MEN 1) while the remaining were sporadic. The sensitivity of pre-operative localization was 61.5% (multiphasic CT), 66.6% (multiphasic MRI), 100% (68Ga Exendin-4 PET-CT), and 91.6% (EUS). Three patients with normal multiphasic CT had localization on 68Ga Exendin-4 PET-CT. The positive predictive value (PPV) of both Exendin-PET-CT and EUS was similar at 91.6% and 91.6%, respectively. All patients (except one with nesidioblastosis), who underwent enucleation or partial pancreatic resection, were cured. Conclusion: 68Ga Exendin-4 PET-CT based is a non-invasive imaging modality that has high sensitivity and PPV and can be used as a first-line imaging modality. The overall prognosis of these tumours is good with high cure rates attained following surgical resection.
RESUMO
Primary hepatic angiosarcoma (PHA) is a rare, rapidly growing, highly aggressive hepatic malignancy, primarily seen in elderly males. Establishing an accurate clinical diagnosis is challenging owing to its rarity and nonspecific presentation. Rendering a cytologic diagnosis of PHA is extremely difficult, and immunocytochemistry(ICC) on cell block(CB) sections is essential to confirm the diagnosis. The characteristic cytomorphologic features of PHA have rarely been documented, further augmenting the diagnostic challenge. A 32-year-old male presented with abdominal pain, abdominal distension, and significant weight loss over the past 9 months. On examination, the abdomen was distended, with multiple spider angiomas and a large mass in the right hypochondrium. His renal function tests, liver function tests, and serum tumor markers were within normal limits. An abdominal triphasic computerized tomography revealed a large lobulated mass in the right lobe with central necrosis. An ultrasound-guided FNA was performed from the liver lesion. The cytologic smears showed singly scattered large, markedly pleomorphic, epithelioid-elongated tumor cells having oval-elongated nuclei, irregular nuclear contours, coarse chromatin, prominent macronucleoli, and abundant finely vacuolated cytoplasm in a background of blood. ICC on the CB demonstrated diffuse positivity for vimentin, CD31, and nuclear positivity for FLI-1, confirming a vascular origin. Hence, a final cytologic diagnosis of primary hepatic angiosarcoma was rendered. The index report describes the characteristic cytomorphologic and immunocytochemical features of a rare hepatic malignancy in a young male and reiterates the usefulness of FNAC coupled with CB-ICC in the quick and precise diagnosis of such challenging cases.
