A Single-center Experience of Radiotherapy in Pediatric Ewing Sarcoma/Primitive Neuroectodermal Tumor of the Chest Wall.

AIM: To evaluate the treatment results, prognostic parameters, and treatment-related toxicity in patients with Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET) of the chest wall who underwent surgery, chemotherapy, and radiotherapy (RT) in a tertiary referral center. METHODS: The data of 24 patients under 18 years of age with a histologic diagnosis of ES/PNET in the chest wall that received RT in our department between February 2003 and July 2020 were retrospectively evaluated. RT was applied to the primary site±whole involved chest wall and to the whole lung in patients with lung metastasis. RESULTS: The median age was 8.5 years (range: 1.5 to 17 y), 15 (63%) patients were female and 9 were male (37%). The tumor localization was extrathoracic in 18 (75%) and intrathoracic in 6 (25%) patients. Mediastinal lymph node and distant metastasis (DM) was present in 5 (21%) and 4 (16%) cases at diagnosis, respectively. The median follow-up after RT was 47 months (range: 11 to 162 mo). The 2-year and 5-year overall survival, event-free survival, local recurrence-free survival, and pleural recurrence-free survival were 83% and 48%, 48% and 42%, 74% and 48%, and 61% and 52%, respectively. The overall local control rate was 83% and the pleural control rate was 67%. RT was well tolerated, with 1 case of grade 3 acute dermatitis and 1 case of grade 3 subacute radiation pneumonitis. Late toxicity was observed in 3 (13%) cases. CONCLUSION: Long-term survival can be achieved with extended-field RT even in patients with ES/PNET of the chest wall with DM. The low toxicity rates allow us to draw the conclusion that RT with modern techniques is an effective and safe treatment modality for these patients.

Ganglioneuromas in Childhood: Hacettepe Experience With 70 Cases.

BACKGROUND: Ganglioneuromas (GNs) are rare benign peripheral neuroblastic tumors (PNTs). We shared our institutional experience with childhood GNs. METHODS: Records of the children with PNTs between January 1995 and December 2021 were reviewed, and cases with histopathological diagnoses of GN were identified. Clinical, laboratory, radiological, and histopathological findings, image-defined risk factors (IDRFs), procedures, and overall outcomes were recorded. RESULTS: Of 668 cases with PNTs, 70 (10.4%) had GNs. The median age was 7.4 years (range, 2.6-15.7 years) (girls/boys, 41/29). Common presenting complaints were abdominal pain and cough; 33/70 cases (47.1%) were diagnosed incidentally. Primary tumors were in the abdomen in 41/70, the thorax in 25/70, the neck in 3 cases, and the pelvis in one. The median tumor size was 6.5 cm (range, 1.4-17). Fifty cases (71.4%) were staged as INRG-L1; 20 cases with IDRFs (15 single, five >1) were staged as INRG-L2. Complete and partial tumor resections were performed in 58/70 and 6/70 cases, while 6 had no resection. The overall complication rate was 17.1% (11/64). At a median follow-up of 9 years, five were lost to follow-up; 65 were alive. One patient with gross residue underwent total resection due to progression 13 years after the surgery, and one in the unresected group was lost to follow-up. Ten other cases without a complete resection experienced no tumor progression. CONCLUSIONS: Ganglioneuromas are benign PNTs, and most are free of IDRFs. Even without complete resection, long-term outcomes are excellent. Guidelines should be devised considering the high surgical complication rates and benign course of GNs. LEVEL OF EVIDENCE: Case series, IV.

Esophageal Carcinoma in Children: Report of 2 Cases and a Review of the Literature.

Esophageal carcinoma in children and adolescents is extremely rare. Here, we report 2 cases of pediatric esophageal carcinoma presenting with progressive dysphagia. There was not any underlying specific risk factor in our cases. The histopathological subtypes were adenocarcinoma in one and squamous cell carcinoma in another case. Response to combined modality treatment was good in the case of adenocarcinoma, while the patient with squamous cell carcinoma was unresponsive to treatment and died of the progressive disease. We reviewed the pediatric cases of esophageal carcinoma reported in the literature. Progressive dysphagia was observed in 89% of these cases. One third of pediatric cases had underlying risk factors. Squamous cell carcinoma is a more common type of childhood esophageal carcinoma. In contrast to adults, pediatric esophageal squamous cell carcinoma may distribute throughout the esophagus. Esophageal adenocarcinoma was seen in the distal esophagus in pediatric cases. Metastatic disease was found in 48% of pediatric patients at presentation, and the prognosis is poor. Collaborative efforts are needed for success in the treatment of esophageal carcinoma.

Childhood interstitial lung disease in Turkey: first data from the national registry.

The childhood interstitial lung diseases (chILD) Turkey registry (chILD-TR) was established in November 2021 to increase awareness of disease, and in collaboration with the centers to improve the diagnostic and treatment standards. Here, the first results of the chILD registry system were presented. In this prospective cohort study, data were collected using a data-entry software system. The demographic characteristics, clinical, laboratory, radiologic findings, diagnoses, and treatment characteristics of the patients were evaluated. Clinical characteristics were compared between two main chILD groups ((A) diffuse parenchymal lung diseases (DPLD) disorders manifesting primarily in infancy [group1] and (B) DPLD disorders occurring at all ages [group 2]). There were 416 patients registered from 19 centers. Forty-six patients were excluded due to missing information. The median age of diagnosis of the patients was 6.05 (1.3-11.6) years. Across the study population (n = 370), 81 (21.8%) were in group 1, and 289 (78.1%) were in group 2. The median weight z-score was significantly lower in group 1 (- 2.0 [- 3.36 to - 0.81]) than in group 2 (- 0.80 [- 1.7 to 0.20]) (p < 0.001). When we compared the groups according to chest CT findings, ground-glass opacities were significantly more common in group 1, and nodular opacities, bronchiectasis, mosaic perfusion, and mediastinal lymphadenopathy were significantly more common in group 2. Out of the overall study population, 67.8% were undergoing some form of treatment. The use of oral steroids was significantly higher in group 2 than in group 1 (40.6% vs. 23.3%, respectively; p = 0.040).   Conclusion: This study showed that national registry allowed to obtain information about the frequency, types, and treatment methods of chILD in Turkey and helped to see the difficulties in the diagnosis and management of these patients. What is Known: • Childhood interstitial lung diseases comprise many diverse entities which are challenging to diagnose and manage. What is New: • This study showed that national registry allowed to obtain information about the frequency, types and treatment methods of chILD in Turkey and helped to see the difficulties in the diagnosis and management of these patients. Also, our findings reveal that nutrition should be considered in all patients with chILD, especially in A-DPLD disorders manifesting primarily in infancy.

Imaging Features of Pediatric Sarcoidosis.

Sarcoidosis is a granulomatous inflammatory disease of uncertain cause. It occurs most commonly in young and middle-aged adults and less frequently in children; therefore, few data on pediatric sarcoidosis exist in the literature. The diagnosis and management of sarcoidosis remain challenging because of diverse and often nonspecific clinical and imaging findings. In addition, the clinical picture varies widely by age. Prepubertal and adolescent patients often present with adult-like pulmonary disease; however, early-onset sarcoidosis is typically characterized by the triad of arthritis, uveitis, and skin rash. Sarcoidosis is mostly a diagnosis of exclusion made by demonstrating noncaseating granulomas at histopathologic examination in patients with compatible clinical and radiologic findings. Although sarcoidosis often affects the lungs and thoracic lymph nodes, it can involve almost any organ in the body. The most common radiologic manifestation is pulmonary involvement, characterized by mediastinal and bilateral symmetric hilar lymphadenopathies with perilymphatic micronodules. Abdominal involvement is also common in children and often manifests as hepatomegaly, splenomegaly, and abdominal lymph node enlargement. Although neurosarcoidosis and cardiac sarcoidosis are rare, imaging is essential to the diagnosis of central nervous system and cardiac involvement because of the risky biopsy procedure and its low diagnostic yield due to focal involvement. Being familiar with the spectrum of imaging findings of sarcoidosis may aid in appropriate diagnosis and management. ©RSNA, 2023 Test Your Knowledge questions are available in the supplemental material.

Low-Grade Injury following Testicular Torsion: A Multicenter Study Confirming a Disturbing Possibility.

INTRODUCTION: There is an ongoing debate whether to perform orchiectomy or orchidopexy following testicular torsion (TT) in cases where the testis seems non-viable. The main problem is lack of objective criteria defining testicular viability. The aim of this study was to investigate the grade of injury in orchiectomy specimens obtained from cases of TT and its association with clinical findings. METHODS: This multicenter retrospective study involved double-blinded reassessment of the patient files and the pathological specimens using Mikuz classification to analyze the relation between clinical and pathological findings. RESULTS: A total of 289 patient charts from 14 centers were reviewed and 228 were included in this study. Twenty (8.8%) patients had grade 1 injury which refers to reversible injury. The clinical findings of these 20 patients were compared to 208 patients with higher grades of injury. As expected, there was statistically significant difference regarding duration of symptoms (p < 0.001); however, range was wide in both groups (as long as 96 h for grade 1 and as short as 7 h for higher grades). There was no statistically significant difference in any other variable including age (median 14 for both, p = 0.531), symptoms (pain: 19/20 vs. 189/202, p = 0.801; swelling: 13/19 vs. 168/197, p = 0.094), absence of blood flow in Doppler US (15/19 vs. 164/197, p = 0.635), or degree of torsion (median 720° for both, p = 0.172). CONCLUSION: Our study revealed necessity for better criteria to define viability of testis following TT. Histopathological injury appeared to be reversible even in some patients with more severe perioperative findings, late admission, or high degree of twisting. Our findings support the tendency for testicular fixation instead of orchiectomy as none of the clinical or perioperative findings could be attributed to high-grade injury.

Hemoglobin cast nephropathy: a rare but serious complication of hemolysis in a pediatric patient.

BACKGROUND: Intravascular hemolysis is a serious and rare condition in children and causes the release of hemoglobin and heme into circulation, which have proinflammatory properties. These substances lead to inflammation, oxidative stress, apoptosis, and organelle dysfunction that lead to acute kidney injury (AKI). We report a pediatric case diagnosed with hemolysis-associated hemoglobin cast nephropathy due to autoimmune hemolytic anemia. CASE: A 4-year-old boy, who was admitted to another hospital with complaints of fever and dark urine for one day, developed anemia and kidney failure in the follow-up, was referred to our hospital. In physical examination, pallor and icterus on the sclera were noted. The patient had low hemoglobin and haptoglobin levels concomitant with high levels of serum lactate dehydrogenase, urea and creatinine. A peripheral blood smear showed marked spherocytes without schistocytes. A kidney biopsy was performed due to ongoing overt hemolysis and dialysis requirement, which showed findings consistent with hemoglobin cast nephropathy. Although the initial polyspecific direct antiglobulin test (DAT) was negative, due to persistent intravascular hemolysis DAT was studied monospecifically and showed IgM antibody positivity. Therefore, a diagnosis of autoimmune hemolytic anemia was made, and corticosteroid treatment was started. Hemolysis immediately ceased and the need for erythrocyte transfusion and dialysis disappeared. CONCLUSIONS: Acute kidney injury associated with hemoglobin cast nephropathy is an extremely rare condition in childhood. Although the initial course is severe and potentially life-threatening, the prognosis is favorable with the treatment of the underlying cause and management of AKI. Therefore, pediatricians should be aware of this rare clinical entity during clinical practice.

Fatal thrombotic microangiopathy in an infant with COVID-19: a case report.

BACKGROUND: While macrovascular thrombosis is common in adult COVID-19 patients, thrombotic microangiopathy as a part of endothelitis might play an important role in severe organ dysfunction. Thrombocytopenia-associated multiple organ failure (TAMOF) is a thrombotic microangiopathy syndrome that is associated with endothelial damage. Herein, we aim to report a pediatric TAMOF case related to SARS-CoV-2 infection which has been scarcely reported to date. CASE: A 7-month-old boy who became severely ill after being infected with SARS-CoV-2 required advanced critical care treatments such as continuous renal replacement therapy, therapeutic plasma exchange, and extracorporeal membrane oxygenation. A heart and lung biopsy obtained during sternotomy showed thrombotic microangiopathy. Despite early plasma exchange, mortality was inevitable because of severe liver failure. CONCLUSIONS: This case report implies that SARS-CoV-2 infection could cause TAMOF in children. To the best of our knowledge, this is the second SARS-CoV-2-induced pediatric TAMOF case. More studies are needed to determine alternative treatments for patients with TAMOF who are resistant to conventional therapies.

Primary ovarian tumors in children: a single center experience of 124 patients.

BACKGROUND: Primary ovarian tumors are rare in the pediatric age group. We reviewed our 40-year experience with ovarian tumors to evalute the clinical features and treatment results in a single institution. METHODS: Between January 1975 and October 2015, 124 girls with primary ovarian tumor were diagnosed and treated in our center. Tumors were identified with biopsy or total resection and/or serum markers. Seventy four children were included in the treatment analysis. RESULTS: Median age for 124 children was 11.0 years (0.73-17.63). The main complaint was abdominal pain in 85 patients (68.5%). One hundred and five patients (84.6%) had total one-sided salpingo-oophorectomy and five patients had bilateral salpingo-oophorectomy. Amongst 124 cases, 29 patients had mature teratoma, which was the most common tumor in this study. Dysgerminoma (n=21) was the most common malignant histopathologic type. Stage I disease was diagnosed in 57.2% and stage IV in 6.6% of the patients. Five year overall survival (OS) and event-free survival (EFS) for 124 children were 82.5% and 76.3% respectively. For 74 children who received treatment, 5-year OS and EFS were 75.2% and 67.1%, respectively. Age (p < 0.017), histopathological subgroup (p < 0.001), stage (p =0.003) and chemotherapy protocols (p =0.049) were significant prognostic factors for OS. CONCLUSIONS: The survival rates in children with ovarian tumors were comparable with studies in the literature. Although patients treated with platin based regimens had better survival rates, prognosis was still poor for the patients in advanced stages. This should be the focus for further studies and improvements.

Endoscopic treatment of periampullary duodenal duplication cyts in an 18-month-old girl.

BACKGROUND: Duodenal duplication cysts (DDC) are rare congenital anomalies of the gastrointestinal tract and periampullary localization with anatomical variants including biliary and pancreatic duct anomalies remains a surgical challenge. Endoscopic treatment of the periampullary DDC (PDDC) communicating with the pancreaticobiliary duct in an 18-month-old girl is presented to discuss the endoscopic treatment options in children. CASE: An 18-month-old girl with a normal prenatal ultrasound (US) was asymptomatic until complaining of abdominal pain and vomiting at 10-months of age. Abdominal US revealed a 1.8 × 2 cm cystic mass adjacent to the second part of the duodenum. The amylase and lipase levels were slightly increased while she was symptomatic. Magnetic resonance cholangiopancreaticography (MRCP) showed a thick cyst wall measuring 1.5 × 2 cm at the second part of the duodenum, consistent with DDC that was suspected to be communicating with the common bile duct. Upper gastrointestinal endoscopy confirmed a bulging cyst in the duodenum lumen. The puncture and injection of the cyst with contrast material confirmed the communication of the duplication cyst with the common bile duct. The unroofing of the cyst was performed with endoscopic cautery. The biopsy obtained from the cystic mucosa revealed normal intestinal histology. Oral feeding was initiated six hours after the endoscopy. The patient has been followed for the last 8 months uneventfully. CONCLUSIONS: Endoscopic treatment of PDDC with various anatomical variants can be considered an alternative to surgical excision in children.

Magnetic resonance elastography in evaluation of liver fibrosis in children with chronic liver disease.

BACKGROUND: Magnetic resonance elastography (MRE) has been used to stage liver fibrosis in adults. We aimed to assess the agreement between the Ishak scoring system and magnetic resonance elastography-measured liver stiffness (MRE-LS) in children. This study included all the children who underwent abdominal MRE and liver biopsies between February 2018 and January 2021. The correlation between MRE-LS and Ishak fibrosis stage, MRE parameters, and clinical and biochemical markers affecting this relationship was investigated. RESULTS: A total of 52 patients (31 male; a median age of 11.8 years) were included in the study. The MRE-LS values were significantly different between Ishak fibrosis stages (p = 0.036). With a cut-off value of 2.97 kilopascals, MRE-LS had sensitivity, specificity, PPV, NPV and accuracy values of 90.9%, 82.9%, 58.8%, 97.1%, and 84.6%, respectively, for differentiating mild/moderate fibrosis (F0, 1, 2, 3) from severe fibrosis (F ≥ 4). Although MRE-LS was moderately correlated with Ishak fibrosis score and histological activity index and weakly correlated with aspartate aminotransferase, hepatic steatosis, and R2*, only Ishak fibrosis score was a significant predictor of MRE-LS. MRE-measured spleen stiffness was weakly correlated with the Ishak fibrosis score. CONCLUSIONS: MRE has high sensitivity and specificity for evaluating liver fibrosis in children. MRE may be used to evaluate liver fibrosis in pediatric patients.

Precursor B-cell Lymphoblastic Lymphoma in Children: Hacettepe Experience.

The purpose of the study was to review the clinical and pathologic characteristics and treatment results of children with precursor B-cell lymphoblastic lymphoma. Of 530 children diagnosed with non-Hodgkin lymphomas between 2000 and 2021, 39 (7.4%) were identified as having precursor B-cell lymphoblastic lymphoma. Clinical characteristics, pathologic, radiologic, laboratory data, treatments, responses, and overall outcomes were recorded from hospital files and analyzed. The median age of 39 patients (males/females, 23/16) was 8.3 years (range 1.3 to 16.1). The most common sites of involvement were the lymph nodes. At a median follow-up of 55.8 months, 14 patients (35%) had a recurrence of disease (11 stage IV, 3 stage III); 4 were in complete remission with salvage therapies, 9 died of progressive disease and one died due to febrile neutropenia. Five-year event-free survival and overall survival rates were 65.4% and 78.3% for all cases, respectively. Survival rates were higher in patients with a complete remission at the end of induction therapies. The survival rates were lower in our study compared with other studies, which could be explained by the high relapse rate and higher incidence of advanced-stage disease due to bone marrow involvement. We demonstrated a prognostic impact of treatment response at the end of the induction phase. Cases with a disease relapse have poor prognosis.

A child presenting with bullous emphysema.

BACKGROUND: Placental transmogrification of the lung (PTL) is a clinical spectrum varying from asymptomatic to severe pulmonary impairment; such as recurrent pneumothorax, bronchopneumonia, respiratory distress syndrome and chronic obstructive airway disease. PTL usually presents as a bullous lesion, and rarely can appear in nodule or cyst formation on chest imaging. PTL with giant bullous emphysema has a male preference, is more commonly unilateral and mostly affects one lobe, but can rarely involve more than one lobe. CASE: Here we report a 13-year-old boy presenting with bullous emphysema and coexisting with a borderline testicular tumor. He had no complaints of cough, sputum, or shortness of breath. He had a past medical history of pneumonia five years ago. In order to elucidate the underlying lung pathology, a wedge lung biopsy was performed and the patient was diagnosed with PTL. Scrotum ultrasonography was performed because of hydrocele in both testes, and bilateral epididymal cysts with papillary solid projections were reported. Pathological examination of the epididymal tumor revealed a `Mullerian type borderline epithelial neoplasm` which is an analogue of the ovarian serous borderline tumor. CONCLUSIONS: In conclusion, we reported the youngest PTL case in the literature, a rare disease with unknown pathophysiology, presenting as bullous emphysema and coincidental Mullerian type borderline epithelial neoplasm. It is important to diagnose placental transmogrification of the lung in a child with bullous emphysema because compared to other cystic lung diseases it is a benign disease and if no additional malignity exists, lobectomy or pneumonectomy is the cure for the disease.

Interstitial Lung Disease in an Adolescent Girl with Lipopolysaccharide-Responsive Beige-Like Anchor Deficiency.

Background: Previously, lipopolysaccharide-responsive beige-like anchor (LRBA) deficiency was categorized as a subtype of common variable immune deficiency. Research shows that LRBA deficiency is caused by dysregulation of T cell activation and expansion; it is placed under the category of immune dysregulation with cytotoxic T lymphocyte-associated protein 4 (CTLA-4) haploinsufficiency. Cohort studies have revealed a broad spectrum of clinical manifestations and variable phenotype expression, including immune dysregulation [enteropathy, autoimmune cytopenia, interstitial lung disease (ILD), etc.] on 1 hand and immune deficiency (hypogammaglobulinemia, recurrent infections, bronchiectasis, etc.) on the other hand. Chronic lung disease is frequently seen in LRBA deficiency and is associated with poor outcomes. Case Presentation: This case report evaluates a female who presented with recurrent pneumonia and bronchiectasis but did not respond to treatment; she was lastly diagnosed with ILD with detailed clinical, radiological, and pathological workup. Conclusions: The respiratory characteristics of patients with LRBA deficiency should be investigated, monitored, and treated from the time of its diagnosis. The awareness and involvement of pulmonologists to pulmonary morbidity of patients with LRBA deficiency in workup and clinical decision making are crucial.

High Inborn Errors of Immunity Risk in Patients with Granuloma.

OBJECTIVE: Granuloma etiology includes infections, vasculitis, chemicals, malignancies, lymphoproliferative disorders, and immunological diseases. We hypothesized that patients with granuloma have an underlying primary immunodeficiency disease (PIDD). PATIENTS AND METHODS: We retrospectively enrolled 82 patients with immunological evaluation among 294 biopsy-proven granuloma patients (0- to 20-year-old). At the same time frame, we followed up with 1910 patients in the same age group. RESULTS: Out of 82 patients, male/female ratio was 45/37. Median age at symptom onset was 5 years (28 days-17.4 years), age of granuloma at diagnosis was 8.6 years (36 days-19.4 years). Common symptoms at disease onset were fever (23.2%), lymphadenopathy (19.6%), abdominal pain (12.2%), and cough (12.2%). Granuloma was frequent in lymph nodes (26.8%), skin (19.5%), lung (13.4%), and bone (11%). Common infectious agents isolated were Mycobacterium spp. (23.2%) and EBV (4.9%). We document PIDD in 76.8% (63/82) of patients. 49.4% (40/81) of immunologically evaluated granuloma patients had hypogammaglobulinemia. Granuloma rate in pediatric PIDD was 3.3%(63/1910). Patients with multiple granulomas (n = 16) had a PIDD diagnosis. Lung involvement was three times more in PIDD. Brain involvement was only seen in PIDD. Fibroadipose tissue and liver involvement were more frequent in patients without documented PIDD and patients whose evaluation was not completed. The mortality rate in PIDD with granuloma was 15.9%, whereas there was no mortality in patients without PIDD. CONCLUSION: As documented here, even in a university hospital, the immunologic evaluation ratio is about one-third. We showed high PIDD frequency in children with granuloma, and higher mortality in PIDD with granuloma. Thus, an immunologic evaluation performed meticulously by immunologists is a must for accurate diagnosis and decision of individualized therapeutic options.

Clinical radiological and pathological staging of children with hypersensitivity pneumonitis.

OBJECTIVE: Hypersensitivity pneumonitis (HP) is rare in the pediatric population. To date, there are no studies defining a correlation between clinical, radiological, and pathological findings in children with HP. The objective of this study is to define the clinical, and radiological characteristics and prognosis of childhood HP and to examine the clinical, radiological, and pathological correlation between HP stages. METHODS: Patients with suspected HP and followed at two tertiary care hospitals between 2000 and 2020 were retrospectively evaluated. Computed tomography (CT) of the chest of patients was evaluated by a single radiologist. The interagreement between clinical and radiological severity of the patients was calculated with the κ test. RESULTS: Fourteen children with suspected HP were identified. The results of 10 patients with the definitive diagnosis were as follows: one patient (10%) had acute, five patients (50%) had subacute, and four patients (40%) had chronic HP. The most prominent findings in chest CT were hilar, or hilar and subcarinal lymphadenopathy (80%), centrilobular nodules (60%), patchy or diffuse ground-glass opacities (50%), and cysts (50%). The interagreement between clinical and radiological severity of the patients was 100% (approximate significance: 0.003). The diagnosis of four patients with suspected HP who were unresponsive to standardized medical treatments or developed multisystem involvement was diagnosed with other diseases. One patient (10%) with definitive chronic HP died due to respiratory failure during follow up. CONCLUSION: Similar to adult HP, the prognosis is worse in children with existing fibrotic equivalents in chest CT. Patients who are not responding to standard medical treatments or develop multisystem involvement should be evaluated for other lung diseases.

Salvage Liver Transplant in the Treatment of a Child With Local Recurrence of Hepatoblastoma.

Hepatoblastoma is the most common primary liver cancer of childhood, accounting for two-thirds of primary malignant hepatic neoplasms. Radical surgical removal combined with efficient chemotherapy is essential for cure. Despite a complete tumor resection, hepatoblastoma may recur as isolated local disease. Intrahepatic recurrence of hepatoblastoma after liver resection is among the indications for liver transplant. Here, we present a patient who underwent salvage liver transplant for the treatment of local recurrence of hepatoblastoma. A 13-year-old boy who was diagnosed with hepatocellular carcinoma arising from the left liver lobe and who had been treated with surgical resection was admitted to our outpatient oncology clinic for further evaluation because alpha-fetoprotein levels had started to increase after surgery. Histopathological reexamination of hemihepatectomy material showed a histological aspect of an epithelial hepatoblastoma. Magnetic resonance imaging revealed multifocal lesions in the right liver lobe compatible with local recurrence. Despite a favorable initial response to chemotherapy, the tumor showed progression with increased alpha-fetoprotein levels. The patient was deemed a viable candidate for an urgent liver transplant and underwent right lobe living donor liver transplant. He had excellent graft function without any complications or signs of malignancy in the last follow-up visit at 7 months posttransplant. Salvage liver transplant is a lifesaving and sometimes the only treatment option for patients with local recurrence of hepatoblastoma. Although transplant in the salvage setting has been associated with worse outcomes than primary transplant, recent data have indicated more favorable and acceptable outcomes. Further studies are warranted to better understand the role of salvage liver transplant in the treatment of hepatoblastoma. Early consultation with the liver transplant team is critical in children who are most likely to need extreme resection or liver transplant.
