RESUMO

Disparities exist in pediatric liver transplant (LT). We characterized barriers and facilitators to providing transplant and social care within pediatric LT clinics. This was a multicenter qualitative study. We oversampled caregivers reporting household financial strain, material economic hardship, or demonstrating poor health literacy. We also enrolled transplant team members. We conducted semistructured interviews with participants. Caregiver interviews focused on challenges addressing transplant and household needs. Transplant provider interviews focused on barriers and facilitators to providing social care within transplant teams. Interviews were recorded, transcribed, and coded according to the Capability, Opportunity, Motivation-Behavior model. We interviewed 27 caregivers and 27 transplant team members. Fifty-two percent of caregivers reported a household income <$60,000, and 62% reported financial resource strain. Caregivers reported experiencing (1) high financial burdens after LT, (2) added caregiving labor that compounds the financial burden, (3) dependency on their social network's generosity for financial and logistical support, and (4) additional support being limited to the perioperative period. Transplant providers reported (1) relying on the pretransplant psychosocial assessment for identifying social risks, (2) discomfort initiating social risk discussions in the post-transplant period, (3) reliance on social workers to address new social risks, and (4) social workers feeling overburdened by quantity and quality of the social work referrals. We identified barriers to providing effective social care in pediatric LT, primarily a lack of comfort in assessing and addressing new social risks in the post-transplant period. Addressing these barriers should enhance social care delivery and improve outcomes for these children.

RESUMO

INTRODUCTION: Liver transplantation (LT) is a technically complex operation and usually performed on ill patients. A major postoperative morbidity is incisional hernia, occurring in 9.5%-32.4% of cases. There are mixed results in transplant studies regarding potential risk factors. Additionally, the literature is lacking in the relationship between specific immunosuppressive induction agents administered during LT and postoperative incisional hernia. METHODS: A single center, retrospective cohort study of patients who underwent primary LT between 4/2011-1/2018 was conducted. Clinical variables including demographics and comorbidities were reviewed. The primary end point was the development of an incisional hernia following LT. Sub analysis was performed for secondary end points to determine potential risk factors, including immunosuppressive induction agent. RESULTS: Overall, 418 patients met inclusion criteria. At 5 y post-LT, there were 66/271 (24.4%) and 53/147 (36.1%) patients diagnosed with an incisional hernia in the methylprednisolone and basiliximab groups, respectively. After propensity score matching, there was no difference in incisional hernia development between induction agents, P = 0.19. For patients with body mass index ≥30 and postoperative seroma of the abdominal wall, the hazard ratios were 2.67 (95% CI = 1.7, 4.3) and 2.03 (95% CI = 1.1, 3.9), respectively. CONCLUSIONS: Incisional hernia rate after LT was 28.5% at 5 y. Our analysis found that immunosuppressive induction agent at LT was not associated with the development of postoperative incisional hernia. However, preoperative obesity (body mass index ≥30) and postoperative seroma of the abdominal wall were potential risk factors. Further studies are needed to delineate if these risk factors remain across institutions and in alternative settings.

RESUMO

BACKGROUND: Approximately 2500 pediatric patients are awaiting kidney transplantation in the United States, with <5% comprising those ≤15 kg. Transplant in this cohort is often delayed by center-based growth parameters, often necessitating transplantation after the initiation of dialysis. Furthermore, prognostication remains somewhat ambiguous. In this report, we scrutinize the Organ Procurement and Transplantation Network (OPTN) data from 2001 to 2021 to help better understand specific variables impacting graft and patient outcomes in these children. METHODS: The OPTN kidney transplant dataset from 2001 to 2021 was analyzed. Inclusion criteria included age <18 years, weight ≤15 kg, and recipient of primary living donor kidney transplantation (LDKT) or deceased donor kidney transplantation (DDKT). Patient and graft survival probabilities were calculated using the Kaplan-Meier method. The Cox proportional hazards model was used to calculate hazard ratio (HR) and identify variables significantly associated with patient and graft survival. RESULTS: Two thousand one hundred sixty-eight pediatric transplant recipients met inclusion criteria. Patient survival at 1 and 3 years was 98% and 97%, respectively. Graft survival at 1 and 3 years was 95% and 92%, respectively. Dialysis was the sole significant variable impacting both patient and graft survival. Graft survival was further impacted by transplant era, recipient gender and ethnicity, and donor type. Infants transplanted at Age 1 had better graft survival compared with older children, and nephrotic syndrome was likewise associated with a better prognosis. CONCLUSION: Pediatric kidney transplantation is highly successful. The balance between preemptive transplantation, medical optimization, and satisfactory technical parameters seems to suggest a "Goldilocks zone" for many children, favoring transplantation between 1 and 2 years of age.

RESUMO

Living donor liver transplantation is an effective means to decrease organ shortage. However, many potential living donors are currently being denied due to ABO incompatibility or inadequate donor liver volume. Liver paired exchange (LPE) provides a practical solution to overcome these obstacles, and yet the first case of LPE in the United States was only recently reported in 2020. Here, we report world's first case of LPE involving pediatric and adult recipients to avoid surgical complexity of the pediatric recipient and to increase the graft-to-recipient weight ratio of the adult recipient between 2 ABO compatible pairs. As living donor liver transplantation becomes more widely adopted, the need for pair exchange to improve surgical safety and postoperative outcomes between 2 ABO compatible pairs is likely to increase.

RESUMO

Although pediatric liver transplantation (LT) results in excellent long-term outcomes, a high incidence of early acute cellular rejection and late graft fibrosis persists. Routine measurement of allograft enzymes may not reliably detect rejection episodes, identify candidates for immunosuppression minimization, or indicate allograft fibrosis. Surveillance biopsies (SBs) can provide valuable information in this regard, but their role in pediatric LT is not fully established. A retrospective cohort of 236 pediatric LT recipients from a high-volume center was studied to characterize the risks and benefits of SB versus for-cause biopsies (FCBs). The study population was 47.1% male and 54.7% Hispanic, and 31% received living donor grafts. Our data suggest that patients in the SB group had better transplant outcomes (rejection-free, graft, and patient survival) compared with patients who had FCBs or who never underwent biopsy. Among 817 biopsies obtained from 236 patients, 150 (18.4%) were SBs. Only 6 patients had a biopsy-related complication, and none were observed in the SB subset. Graft biochemical blood tests did not accurately predict rejection severity on biopsy, with aspartate aminotransferase area under the receiver operating characteristic curve (AUROC) 0.66, alanine aminotransferase AUROC 0.65 (very poor predictions), and gamma-glutamyltransferase AUROC 0.58 (no prediction). SBs identified subclinical rejection in 18.6% of biopsies, whereas 63.3% of SBs had evidence of fibrosis. SBs prompted changes in immunosuppression including dose reduction. Our experience suggests that SB in pediatric LT is safe, offers valuable information about subclinical rejection episodes, and can guide management of immunosuppression, including minimization. Improved outcomes with SB were likely multifactorial, potentially relating to a more favorable early posttransplant course and possible effect of management optimization through SB. Further multicenter studies are needed to examine the role of SBs on long-term outcomes in pediatric LT.

RESUMO

BACKGROUND: Pediatric liver transplant (LT) recipients of maternal living liver donor (LLD) grafts have been reported to experience fewer rejection episodes. However, it is unclear whether this benefit translates to reduction in developing donor-specific antibody (DSA) among maternal-LLD recipients. The aim of this study was to compare immunologic outcomes among maternal-LLD, non-maternal-LLD, and deceased donor liver transplant (DDLT) recipients. METHODS: Children (≤18 years) who underwent LT between 1/1998 and 12/2019 at two high-volume LT centers in North America were evaluated. Patients were divided into three groups by type of graft received (maternal-LLD, non-maternal LLD, and DDLT). Clinical variables and outcomes were compared according to each graft type. RESULTS: A total of 450 pediatric primary LT were analyzed: 275 (61.1%) DDLT, 73 (16.2%) maternal-LLD, and 102 (22.6%) non-maternal-LLD. Children receiving LLD grafts were less likely to develop rejection when compared to the DDLT group (DDLT 46.9% vs. maternal-LLD 31.5% vs. non-maternal-LLD 28.4%, p = 0.001). There was no difference in rejection rates between maternal and non-maternal-LLD recipients. A higher percentage of maternal-LLD recipients were on immunosuppression monotherapy compared to non-maternal-LLD and DDLT recipients (6.7% vs. 1.2 vs. 2.4%, respectively). A subgroup of 68 patients were tested for DSA post-LT. Maternal-LLD recipients were less likely to develop de novo DSA (maternal-LLD 11.8% vs. non-maternal-LLD 19.3% vs. DDLT 43%, p = 0.018). None of the maternal-LLD recipients developed antibody-mediated rejection. CONCLUSIONS: These data support the concept of immunologic benefit of maternal-LLD in pediatric LT, with lower rates of rejection and allosensitization post-LT when compared to DDLT recipients.

RESUMO

BACKGROUND: Extrahepatic portal vein obstruction (EHPVO) causes portal hypertension in noncirrhotic children. Among surgical treatments, it is unclear whether the meso-Rex shunt (MRS) or portosystemic shunt (PSS) offers lower post-operative morbidity and superior patency over time. Our objective was to evaluate long-term outcomes comparing MRS and PSS for pediatric patients with EHPVO. METHODS: A systematic review was conducted of articles reporting children undergoing surgical shunts for EHPVO from 1/2000-2/2020. Of 87 articles screened, 22 were eligible for inclusion. The primary outcome was shunt thrombosis and secondary outcomes included non-operative complications, stenosis, and re-operation. RESULTS: Eighteen of 22 studies were of good quality and four had fair quality. Of 461 patients included, 340 underwent MRS and 121 underwent PSS. MRS were associated with a higher rate of post-operative thrombosis when compared to PSS (14.1% vs 5.8%, p = 0.021). There were 40/340 MRS patients (11.8%) that required at least one re-operation for either shunt thrombosis or stenosis, versus 5/121 PSS patients (4.1%), p = 0.019. CONCLUSION: Both MRS and PSS result in acceptable long-term patency rates, but the more technically demanding MRS is associated with higher post-shunt thrombosis, often requiring further operative intervention. This study suggests that PSS may offer advantages for pediatric patients with EHPVO.

RESUMO

Background: Bile duct injury (BDI) is one of the most severe complications during cholecystectomy. Early identification of risk factors for BDI may permit risk reduction strategies and inform patient consent.Objective: This study aimed to define patient, provider, and systemic factors associated with BDI; BDI incidence; and short-term outcomes of BDI after urgent cholecystectomy.Methods: Patients who underwent urgent cholecystectomy for acute cholecystitis were retrospectively screened (2020-2022). All patients who sustained BDI were included without exclusions. Demographics, clinical data, and outcomes were collected and compared with descriptive statistics.Results: During the study period, BDI occurred in 4 (0.5%) of 728 patients who underwent urgent cholecystectomy for acute cholecystitis. Most BDI cases (75%) took place overnight or during the weekend. The attending surgeon was almost exclusively (75%) in their first year of practice. BDI was recognized during index operation in 2 cases (50%). Hepatobiliary surgery performed the bile duct repair in all 4 cases. Two complications occurred (50%). All patients were followed by hepatobiliary surgery in the outpatient setting and returned to their baseline level of function within 2 months of hospital discharge.Conclusion: Most BDI occurred in procedures attended by first-year faculty during after hours cholecystectomies, suggesting a role for increased proctorship in early career attendings in addition to in-hours cholecystectomy for acute cholecystitis. The timely return to baseline function experienced by these patients emphasizes the favorable outcomes associated with early recognition of BDI and involvement of hepatobiliary surgery. Further examination with multicenter evaluation would be beneficial to validate these study findings.

RESUMO

BACKGROUND: The social determinants of health contribute to adverse post-liver transplant outcomes. Identifying unmet social risks may enable transplant teams to improve long-term outcomes for at-risk children. However, providers may feel uncomfortable asking about household-level social risks in the posttransplant period because they might make their patients/families uncomfortable. METHODS: We conducted a mixed-methods analysis of caregiver participants (ie, parents/guardians of pediatric liver transplant recipients) in the Social and Contextual Impact on Children Undergoing Liver Transplantation study to assess their perceptions of provider-based social risk screening. Participants (N = 109) completed a 20-min social determinants of health questionnaire that included questions on the acceptability of being asked intimate social risk questions. A subset of participants (N = 37) engaged in an in-depth qualitative interview to share their perceptions of social risk screening. RESULTS: Of 109 participants across 9 US transplant centers, 60% reported financial strain and 30% reported at least 1 material economic hardship (eg, food insecurity, housing instability). Overall, 65% of respondents reported it very or somewhat appropriate and 25% reported being neutral to being screened for social risks in a liver transplant setting. In qualitative analyses, participants reported trust in the providers and a clear understanding of the intention of the screening as prerequisites for liver transplant teams to perform social risk screening. CONCLUSIONS: Only a small minority of caregivers found social risk screening unacceptable. Pediatric liver transplant programs should implement routine social risk screening and prioritize the patient and family voices when establishing a screening program to ensure successful implementation.

RESUMO

BACKGROUND: The kidney transplant waiting list continues to expand, resulting in prolonged dialysis times exceeding 8 years before transplantation in some regions. The relationship between long-term dialysis and urinary tract complications after kidney transplant remains largely unexplored. This study aims to evaluate post-kidney transplant complications in patients with a history of prolonged dialysis. METHODS: A single-center, retrospective cohort study of patients maintained on dialysis ≥8 years before kidney transplant between January 2000 and July 2020 was conducted. Clinical variables, including demographics and comorbidities, were reviewed. The primary objective was the development of a technical urinary tract complication. Secondary outcomes included any postoperative complication by type, stratified by medical and surgical complications. RESULTS: Overall, 376 patients met the inclusion criteria. The mean pre-kidney transplant dialysis time was 10.2 ± 2.6 years. The majority (65.7%) of the study participants were anuric. Four patients (1.1%) experienced a urine leak, and 8 patients (2.1%) had a ureteral stricture. Any complication was observed in 111 (29.5%) patients, with urinary tract infections being the most common. Urinary catheters remained in place for a median of 4 (3, 5) days. Drains were commonly used (62.8%) for a median of 5 (4, 6) days. CONCLUSION: In our large, single-center experience with kidney transplants in high-risk patients with prolonged dialysis and anuria, the technical urinary tract complications rate remained low. With the current literature consisting of small cohorts and having relatively short pre-kidney transplant dialysis periods, our analysis addresses the shortcomings of the literature while suggesting that this patient population may not truly be "high risk."

RESUMO

OBJECTIVES: Liver transplant is emerging as a potential treatment option for patients with isolated colorectal liver metastasis. In this review article, we analyzed the published literature on liver transplant outcomes in such patients. MATERIALS AND METHODS: Four prospective studies documenting the clinical outcomes in patients with colorectal liver metastasis who underwent liver transplant were analyzed to study the feasibility of liver transplant in such patients. RESULTS: The SECA-II trial demonstrated the highest overall survival of 100%, 83%, and 83% at 1, 3, and 5 years, respectively, and disease-free survival of 53%, 44%, and 35%, respectively, with a narrow inclusion criterion. Conversely, extended criteria for selection and donors in arm D of the same trial resulted in median overall survival and disease-free survival of 18 and 4 months, respectively. CONCLUSIONS: Liver transplant provided more prolonged overall survival compared with other therapeutic modalities. Patients with isolated colorectal liver metastasis of less aggressive biology, good performance status, at least 6 weeks of chemotherapy, low clinical risk scores, and negative nodal disease should be considered for patient selection. Moreover, exclusion criteria consisting of patients with the right-sided primary tumor, less than 3 years to liver transplant after diagnosis, and elevation of carbohydrate antigen (CA19-9) in the presence of BRAF mutation should be explored.

RESUMO

BACKGROUND: There are several case reports of acute cholecystitis as the initial presentation of lymphoma of the gallbladder; all reports describe non-Hodgkin lymphoma or its subtypes on histopathology of the gallbladder tissue itself. Interestingly, there is no description in the literature of Hodgkin lymphoma causing hilar lymphadenopathy, inevitably presenting as ruptured cholecystitis with imaging mimicking gallbladder adenocarcinoma. CASE SUMMARY: A 48-year-old man with a past medical history of diabetes mellitus presented with progressive abdominal pain, jaundice, night sweats, weakness, and unintended weight loss for one month. Work-up revealed a mass in the region of the porta hepatis causing obstructions of the cystic and common hepatic ducts, gallbladder rupture, as well as retroperitoneal lymphadenopathy. The clinical picture and imaging findings were suspicious for locally advanced gallbladder adenocarcinoma causing ruptured cholecystitis and cholangitis, with metastases to retroperitoneal lymph nodes. Minimally invasive techniques, including endoscopic duct brushings and percutaneous lymph node biopsy, were inadequate for tissue diagnosis. Therefore, this case required exploratory laparotomy, open cholecystectomy, and periaortic lymph node dissection for histopathological assessment and definitive diagnosis. Hodgkin lymphoma was present in the lymph nodes while the gallbladder specimen had no evidence of malignancy. CONCLUSION: This clinical scenario highlights the importance of histopathological assessment in diagnosing gallbladder malignancy in a patient with gallbladder perforation and a grossly positive positron emission tomography/computed tomography scan. For both gallbladder adenocarcinoma and Hodgkin lymphoma, medical and surgical therapies must be tailored to the specific disease entity in order to achieve optimal long-term survival rates.

RESUMO

BACKGROUND: Biliary complications in liver transplantation (LT) can cause significant morbidity or even lead to a potential graft loss and patient mortality. Oftentimes biliary internal stents (ISs) are used at the time of LT to lower the risk for or prevent these biliary complications; however, their efficacy and outcomes remain controversial. METHODS: A retrospective cohort study was conducted on all of the adult patients who underwent a deceased-donor LT (DDLT) with an end-to-end choledococholedocostomy. An IS was placed across the biliary anastomosis, passing through the ampulla. We compared the demographic profiles and various outcomes between the 2 groups (no-IS group vs IS group) and examined risk factors associated with anastomotic biliary complications. RESULTS: The study comprised 350 patients in the no-IS group and 132 patients in the IS group. Anastomotic biliary fistula (ABF) occurred in 5 (1.4%) and 1 (0.8%) patients in the no-IS group and the IS group, respectively (P = .55). Anastomotic biliary stricture (ABS) occurred in 53 (15.1%) and 18 (13.6%) patients, respectively (P = .68). No significant difference was found in the overall biliary complications between the 2 groups (P = .33). In multivariate logistic regression analysis, acute rejection was the only risk factor for ABS (P = .02). One biliary complication-induced mortality occurred in the no-IS group in which the patient died of an ABF-induced hepatic artery pseudoaneurysm rupture. CONCLUSION: The use of biliary ISs in DDLT did not reduce the overall risk for biliary complications, but more research is needed to draw definite conclusions.

RESUMO

End-stage liver disease (ESLD) patients requiring intensive care unit (ICU) care before liver transplantation (LT) often experience significant muscle mass loss, which has been associated with mortality. In this exploratory study, we primarily aimed to assess the feasibility of serial ultrasound (US) rectus femoris muscle area (RFMA) measurements for the evaluation of progressive muscle loss in ICU-bound potential LT candidates and describe the rate of muscle loss as assessed by sequential US RFMA measurements. Secondarily, we sought to identify patient characteristics associated with muscle loss and determine how muscle loss is associated with survival. METHODS: We prospectively enrolled 50 ESLD adults (≥18 y old) undergoing evaluation for LT candidacy in the ICU. A baseline computed tomography measurement of psoas muscle area (PMA) and serial bedside US measurements of RFMA were obtained. The associations between patient characteristics, PMA, RFMA, ICU stay, and survival were analyzed. RESULTS: Rapid decline in muscle mass by RFMA measurements was ubiquitously present and correlated to baseline PMA and length of ICU stay. RFMA normalized by body surface area decreased by 0.013 cm2/m2 (95% confidence interval, 0.010-0.016; P < 0.001) for each day in the ICU. Decreased RFMA normalized by body surface area was associated with poor overall survival (adjusted hazard ratio, 0.42; 95% confidence interval, 0.18-0.99; P = 0.047). CONCLUSIONS: In this exploratory, prospective study, serial US RFMA measurements in ESLD patients in the ICU are feasible, demonstrate progressive time-dependent muscle loss, and are associated with mortality. Further large-scale assessment of this modality compared with static PMA or performance-based dynamic assessments should be performed.

RESUMO

Central venous catheters (CVC) are commonly used across multiple medical specialties and are inserted for various reasons. A known, but rare, serious complication of CVC is fracture and retention of residual catheter. Here we describe a chronically retained catheter within the inferior vena cava (IVC) that was asymptomatic and neither diagnosed nor addressed until time of deceased donor liver donation. Prior to transplantation into the recipient, the retained catheter was removed, and a venoplasty of the suprahepatic IVC, middle hepatic vein, and left hepatic vein was performed with no significant issues after transplant in the recipient. With the persistent shortage of suitable organs for transplant leading to patients dying on the waiting list, every good quality organ should be carefully considered. Thus, even though a chronically retained, fractured CVC in a deceased organ donor presents a unique challenge, it can be managed surgically and should not be considered a contraindication to organ utilization.

RESUMO

The objective of the study was to determine the long-term stricture rate of hepaticojejunostiomy (HJ) performed for benign disease, to compare stricture rates for transplant patients and nontransplant patients, and to compare the success rates of procedural and surgical treatment options. Hospital charts of 135 consecutive patients undergoing HJ between 1998 and 2016 were analyzed retrospectively. The primary outcome was stricture formation. Secondary outcomes were time to stricture diagnosis and success rates of various interventions. The anastomotic stricture rate was 13.3 per cent (18). The mean follow-up period was 4.3 years. The mean time to stricture diagnosis was 2.3 years. Stricture rates were similar between the transplant (19.2%) and nontransplant, non-Whipple group (13%). Strictures were treated with radiological intervention with a 44.4 per cent success rate; each required multiple interventions. Mortality from liver disease after failure of nonoperative management of HJ strictures reached 30 per cent (3). Five of ten patients who failed radiological intervention underwent HJ revision; the success rate was 80 per cent. Anastomotic strictures of HJ performed for benign disease occur in 13 per cent of patients and typically develop within 2.5 years postoperatively. Yet, given the dangerous sequelae of chronic biliary obstruction and potential delay in presentation, a follow-up is recommended for up to 10 years. When strictures occur, HJ revision should be considered early, after two failed radiological interventions.

The superficial radial artery is an anatomic variant in which the radial artery passes superficial to the tendons of the anatomic snuffbox. Cadaver studies have shown its incidence to be 0.5% to 1%. Four patients with this anatomic variation were encountered in our practice, and their clinical courses and anatomy are described. One patient presented with digital ischemia after catheter placement in the anomalous radial artery. Three patients with end-stage renal disease were found to have a superficial radial artery incidentally, and this was used for inflow in the creation of hemodialysis fistulas.

RESUMO

It is well known that liver disease has an adverse effect on postoperative outcomes. However, what is still unknown is how to appropriately risk stratify this patient population based on the degree of liver failure. Because data are limited, specifically in general surgery practice, we analyzed the model of end-stage liver disease (MELD) in terms of predicting postoperative complications after one of three general surgery operations: inguinal hernia repair (IHR), umbilical hernia repair (UHR), and colon resection (CRXN). National Surgical Quality Improvement Program data on 17,812 total patients undergoing one of three general surgery operations from 2008 to 2012 were analyzed retrospectively. There were 7402 patients undergoing IHR; 5014 patients undergoing UHR; 5396 patients undergoing CRXN. MELD score was calculated using international normalized ratio, total bilirubin, and creatinine. The primary end point was any postoperative complication. The statistical method used was logistic regression. For IHR, UHR, and CRXN, the overall complication rates were 3.4, 6.4, and 45.9 per cent, respectively. The mean MELD scores were 8.6, 8.5, and 8.5, respectively. For every 1-point increase greater than the mean MELD score, there was a 7.8, 13.8, and 11.6 per cent increase in any postoperative complication. The overall 30-day mortality rate was 0.9 per cent. In conclusion, the MELD score continuum adequately predicts patients' increased risk of postoperative complications after IHR, UHR, and CRXN. Therefore, MELD could be used for preoperative risk stratification and guide clinical decision making for general surgery in the cirrhotic patient.

RESUMO

We are reporting the first documented case of an abdominal desmoid tumor presenting primarily after liver transplantation. This tumor, well described in the literature as occurring both in conjunction with familial adenomatous polyposis as well as in the post-surgical patient, has never been noted after solid organ transplantation and was therefore not included in our differential upon presentation. Definitive diagnosis required the patient to undergo surgical excision and immunochemical staining of the mass for confirmation. A review of the literature showed no primary tumors after transplantation. In a population of patients who received a small bowel transplant after they developed short gut post radical resection of aggressive fibromatosis, only rare recurrences were seen. No connection of tumor development with immunosuppression or need to decrease immunosuppressant treatment has been demonstrated in these patients. Our case and the literature show the risk of this tumor presenting in the post-transplantation patient and the need for a high index of suspicion in patients who present with a complex mass after transplantation to prevent progression of the disease beyond a resectable lesion. Results of a thorough search of the literature are detailed and the medical and surgical management of both resectable and unresectable lesions is reviewed.
