Abstract
Heterozygous loss-of-function variants in the suppressor of fused protein gene (SUFU) can result in Gorlin syndrome, which is characterized by an increased frequency of basal cell carcinoma, medulloblastoma, odontogenic keratocysts, as well as other tumors. We describe a case of a 5-month-old female who presented with multiple intra-abdominal leiomyomata and was found to have a likely pathogenic splice site variant in the SUFU gene. This is the first reported case of leiomyomatosis secondary to a pathogenic SUFU variant in an infant and may represent an early, atypical presentation of Gorlin syndrome.

Abstract
Epstein-Barr virus-associated smooth pulmonary tumor is a rare condition that mostly affects immunosuppressed patients. This case describes a young boy with a history of kidney transplantation who presented recurrent pneumonia. Multiple endobronchial soft tissue tumors affecting both right and left bronchial tree were found and partially removed by bronchoscopy. Immunohistologic analysis demonstrated Epstein-Barr virus-associated smooth pulmonary tumor. Immunosuppressive therapy was changed from tacrolimus to sirolimus. A few months later, new right upper lobe and inferior left lobe tumors were found. Recurrent left lower lobe pneumonia prompted lobectomy. In the present case, complete resection and change of immunosuppressive treatment were effective.

Epstein-Barr virus-associated smooth muscle tumor in a kidney transplant recipient: A case-report and review of the literature. Transpl Infect Dis 2020; 23:e13456. [PMID: 32881184 DOI: 10.1111/tid.13456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 08/11/2020] [Accepted: 08/15/2020] [Indexed: 11/27/2022]
Abstract
INTRODUCTION Epstein-Barr virus (EBV) is a herpesvirus linked to pre-malignant lymphoproliferative diseases and up to nine distinct human tumors. The most frequent EBV-associated malignancies are lymphomas and nasopharyngeal carcinoma. By promoting smooth muscle proliferation, EBV can induce EBV-associated smooth muscle tumors (SMT) which remain a very rare oncological entity. This study reports one case report of SMT and aims to offer the largest review of literature on post-transplantation-SMT (PT-SMT) in kidney transplant recipients, with a focus on therapeutic management and evolution of graft function. METHODS Case reports and case series of PT-SMT in kidney transplant recipients were collected from 1996 to 2019. RESULTS A total of 59 PT-SMT were evaluated. The median time at diagnosis was 74.6 months after kidney transplantation. The most frequent localizations were liver and lung. EBV seroconversion was notified in all six patients with previously negative status. Preferred therapeutic option was surgery (65.9%), associated with a reduction in immunosuppression (77.2%), which includes switch to mTOR inhibitors (29.5%), and discontinuation of MMF (32%). In our review, 13% of patients experienced rejection, 8.7% lost their graft and went back on hemodialysis; 8.8% of patients died of PT-SMT. CONCLUSION PT-SMT is a rare but serious condition in kidney transplant recipients. EBV seroconversion following transplantation appears as a risk factor in developing PT-SMT in solid-organ recipients. In the absence of guidelines, therapeutic management for PT-SMT is challenging and exposes the patient to high risk of graft loss.

Abstract
Renal leiomyoma is a rare benign mesenchymal tumor. It arises from the smooth muscle cells of the kidney and renal capsule is its most common location. Small tumor may be asymptomatic and usually appears as a well circumscribed peripherally located solid mass. Large tumor may manifest with pain, palpable flank mass or hematuria. Intersecting fascicles of spindle cells showing immunoreactivity to actin or desmin are characteristic histologic features. We present a case of giant renal leiomyoma in a 20-year-old female with chief complaints of abdominal discomfort and lump in her left side of abdomen. AP radiograph showed a large abdominopelvic soft tissue opacity. Contrast-enhanced computed tomography scan revealed a massive well circumscribed exophytic complex solid cystic mass of size 17 cm × 15 cm × 13 cm arising from upper pole of left kidney. The role of percutaneous biopsy is limited in such lesions and surgery is the only therapeutic option.

Abstract
INTRODUCTION Epstein-Barr virus (EBV) associated smooth muscle tumors (EBV-SMT) are a rare complication of solid organ transplantation (SOT). Incidence data related to this EBV-SMT are limited. EBV DNA is universally present in these tumors. How these cells get infected with EBV, whether this is a result of primary EBV infection vs reactivation, and how persistent active EBV infection post-transplant influences EBV-SMT pathogenesis remains unknown. METHODS Among 5006 SOT recipients (474 pediatric, 4532 adult) receiving SOT at our center between Jan 1984 and Dec 2015, three cases of post-transplant EBV-SMT were identified. RESULTS All cases were pediatric heart transplants who were EBV seronegative prior to transplant, and experienced primary EBV infection with persistently elevated EBV viral loads, despite antiviral therapy. Two are deceased at 3.2 and 0.9 years post-diagnosis, while one remains alive 6.2 years post diagnosis. The overall local incidence of post-transplant EBV-SMT at our institution was 0.7 (95% CI, 0.2-1.7) per 1000 patient years, and 2.6 (95% CI, 0.6-6.7) per 1000 patient years in pediatric heart transplants. A literature review identified 36 pediatric and 51 adult cases of post-transplant EBV-SMT. CONCLUSIONS We hypothesize that pre-transplant EBV seronegativity, followed by primary EBV infection and persistently high EBV viral loads, represents a unique risk factor for post-transplant EBV-SMT. Pediatric heart transplant recipients were found to be disproportionately affected by post-transplant EBV-SMT at our institution.

Abstract
BACKGROUND Kidney transplant (KT) recipients have a higher incidence of malignancy than the general population. Smooth muscle tumors (SMT), including leiomyosarcoma, are rare in kidney transplant recipients, and most cases are associated with Epstein-Barr virus (EBV) infection. CASE REPORT A 57-year-old man received a deceased donor kidney transplant at the age of 53 years, with 5 human leukocyte antigen (HLA) mismatches. Before the transplantation, the patient was IgG positive for EBV viral capsid antigen (VCA), negative for IgM EBV VCA, and also negative for IgG EBV nuclear antigen (EBNA), suggesting a prior EBV infection. He received immunosuppressive induction with basiliximab, and maintenance with tacrolimus, mycophenolate mofetil, and prednisolone. Two years after transplantation, he had an acute cellular rejection episode treated with methylprednisolone. An increased graft size was found 4 years after transplantation. A computed tomographic scan showed 3 solid tumors involving the renal graft with extension to the perinephric fat; no secondary localizations were found. A nephrectomy of the graft was performed. The histologic diagnosis was a high-grade leiomyosarcoma. In situ hybridization for EBV was negative. Nine months after nephrectomy, local recurrence was diagnosed. The surgical approach was unsuccessful, and the patient died after a brief period. CONCLUSION Kidney leiomyosarcoma is a very rare clinical condition. Most of these neoplasms that arise in transplanted recipients are associated with EBV in tumor tissue. Only one case of renal graft leiomyosarcoma without EBV RNA in the tumor has been previously reported.

Abstract
Leiomyomas are smooth muscle tumours that are rarely found in the kidney. There is one report of a leiomyoma in a kidney transplant in a paediatric recipient. Here, we report an adult renal transplant recipient who developed an Epstein-Barr virus-positive leiomyoma in his allograft 15 years after transplantation. The patient was converted to everolimus for posttransplant immunosuppression management and there was no sign of progression over a year.

Abstract
EBV-SMT are a rare entity following organ transplantation. Given the rarity of the tumor, there is no standard approach to diagnosis and treatment. A literature search identified 28 reported cases of EBV-SMT in addition to our own experience with one case. The aim of this review is to summarize the existing data regarding pathogenesis, diagnosis, and treatment.

Abstract
Leiomyomas are benign smooth-muscle tumors that have only rarely been reported in the head and neck. Extensive calcification (mummification) is occasionally seen in deep somatic soft-tissue leiomyomas, which represent a rare subtype. We describe a case of mummified leiomyoma of the soft tissues of the midline anterior neck in a 31-year-old man. His tumor was successfully managed with surgical excision. To the best of our knowledge, this case represents the only description of a mummified leiomyoma at this particular site and the first reported case of any leiomyoma at this site in more than 50 years. We also review the literature concerning leiomyomas of the head and neck, their subtypes, diagnostic and management considerations, and outcomes.

Abstract
Infantile hypertrophic pyloric stenosis is a concerning cause of nonbilious vomiting in the neonatal population. Although a number of etiological theories exist, its exact cause remains nebulous. The question of an infectious etiology (or contribution) has been previously examined in case reports and case series, with recent support through suggestions of seasonality and familial aggregation with unclear inheritance patterns. The present review discusses the published literature regarding infectious etiologies of infantile hypertrophic pyloric stenosis. Furthermore, it attempts to demonstrate that newer research regarding an NOS1 genetic etiology does not exclude, but rather can be consistent with, an infectious etiology.

Abstract
Epstein-Barr virus (EBV) may present few or no symptoms in immunocompetent individuals; however, in immunocompromised patients as in the case of AIDS and post-transplant patients, the virus occasionally stimulates neoplastic transformations. Epstein-Barr virus may play a role in the development of smooth muscle tumors (SMT). In the case of Epstein-Barr associated smooth muscle tumors (EBV+SMT), the virus is thought to be the leading factor to the tumorigenic pathway. We report two pediatric patients (6 and 13 years old) who underwent liver transplantation and developed EBV+SMT in the colon and orbit. These two cases represent rare locations for this kind of lesion.

Abstract
PURPOSE OF REVIEW In immunodeficiency, an increased sarcoma risk is confirmed for Kaposi's sarcoma. Whether rates of other sarcoma subtypes are elevated in the setting of immunodeficiency is not known. We therefore reviewed published case reports on HIV and AIDS patients and organ transplant recipients with sarcomas. For comparison, we assessed sarcomas in the U.S. general population using Surveillance Epidemiology End Results (SEER) data. RECENT FINDINGS A total of 176 non-Kaposi sarcoma were identified, 75 in people with HIV and AIDS and 101 in transplant recipients. Leiomyosarcomas (n = 101) were the most frequently reported sarcomas, followed by angiosarcomas (n = 23) and fibrohistiocytic tumors (n = 17). Leiomyosarcomas were reported with two age peaks, in children and young adults. Epstein-Barr virus (EBV) was detected in the tumor cells in 85 and 88% of leiomyosarcomas in HIV-infected people and transplant recipients, respectively. Angiosarcomas and fibrohistiocytic tumors were most frequently reported in men. Among kidney transplant recipients, 20% of sarcomas arose at the site of an arteriovenous fistula. In comparison, leiomyoscarcomas, angiosarcomas, and fibrohistiocytic tumors comprised 16.9, 3.8, and 18.7% of sarcomas in the U.S. general population. SUMMARY Leiomyosarcoma and angiosarcoma may occur disproportionately in immunodeficiency. Leiomyosarcomas appear causatively linked to EBV, whereas angiosarcomas might be correlated with an arteriovenous fistula. Additional studies are necessary to understand the contribution of immunodeficiency to the cause of these sarcomas.

Abstract
Epstein-Barr virus (EBV)-associated posttransplant smooth muscle tumors (PTSMT) are very rare complications. We aimed to provide a clinicopathological characterization which is based on our own case series (n = 5) as well as previously reported PTSMT cases (n = 63). Meta-analysis of PTSMT and molecular analysis of tumor cells from our cohort was performed. Most PTSMT developed in kidney-transplanted patients (n = 41/68, 60%). Liver/transplant liver was the main site of manifestation (n = 38/68, 56%). Tumors occurred after a median interval of 48 months (range 5-348) and developed earlier in children than in adults. Most tumors showed no marked cellular atypia, low mitosis rate and no tumor necrosis. Gene expression analysis of 20 EBV-related genes, including two microRNAs, revealed overexpression of MYC (p = 0.0357). Therapy was mainly based on surgical resection or reduced immunosuppression but no significant differences in overall survival were evident. Lower overall survival was associated with multiorgan involvement (n = 33/68, 48.5%) and particularly with intracranial PTSMT manifestation (n = 7/68, 10%; p < 0.02), but not transplant involvement (n = 11/68, 16%). In summary, PTSMT differ from conventional leiomyosarcomas by their lack of marked atypia, unusual sites of involvement and defining EBV association. Surgery and reduced immunosuppression show comparable clinical results and prognosis is associated with intracranial manifestation.

Abstract
EBV-associated SMTs in immuno-compromised patients have recently been reported. We report on a case of EBV-associated pulmonary leiomyosarcoma arising five yr after renal transplantation. The patient was an eight-yr-old girl, who received a living related kidney transplant from her mother. She had had bilateral giant Wilm's tumors as an infant and underwent bilateral nephrectomy at one and two yr of age. At the age of seven, she suffered from bronchitis several times, and a year later, two nodules were detected in her left lung by X-ray and computed tomography. We suspected a recurrence of Wilm's tumor and performed surgical resection. The pathological finding was SMT with moderate mitosis and no evidence of Wilm's tumor. The fact that the tumors were positive for EBER suggested an association with the EBV. Six months later, there was a recurrence in her left lung. Surgical resection was performed, and immunosuppressive agents were reduced. Two yr after the second operation, she is well with no recurrence. We report the first case of EBV-associated pulmonary leiomyosarcoma in a pediatric patient after renal transplantation owing to a malignant tumor.

Abstract
The incidence of neoplastic complications after solid organ transplantation is increasing tremendously probably as the consequence of long term immunosuppression. Beside usual risk factors, the oncogenic role of some viruses like Epstein-Barr virus is well established. We report a case of a primitive EBV-induced liver leiomyosarcoma after renal transplantation.

Abstract
This article reports the clinical and the histological features in a 7-year-old girl affected by common variable immunodeficiency (CVID) who developed multiple Epstein-Barr virus-associated tumors, represented by bilateral adrenal smooth muscle tumors (EBV-SMT) and multifocal diffuse large B-cell lymphoma. The EBV-SMTs showed features compatible with a benign or at least a low-malignant potential neoplasm. A peculiar feature observed in both EBV-SMTs was the occurrence of numerous lymphocytes intermingled with the spindle cells, which consisted of CD3+ CD5+ T-cells, with a predominant cytotoxic CD8+ component. Interestingly, EBV status differed in the neoplasms, since the EBV-SMTs were negative for LMP1 and positive for EBER, whereas the B-cell lymphoma expressed both EBV markers. Furthermore, EBV-LMP1 deletion was positive only in the EBV-SMTs, thus indicating that these tumors were the consequence of 2 distinct, EBV-dependent transformations. Similarly, lymphocyte clonality assay also showed different clonal bands in different sites (skin and nasal cavity), suggesting the development of intratumoral mutations. Finally, the authors review all 127 previously reported EBV-SMT, with discussion of their clinical and pathological features.

Abstract
Epstein-Barr virus (EBV) has been implicated in the pathogenesis of different types of malignancies. While nonmelanoma skin cancers, lymphomas and Kaposi sarcomas are the most frequently reported malignancies after solid organ transplantation, EBV-associated smooth muscle tumors (EBV-SMT) after transplantation are rare and thus far only 18 cases in kidney recipients have been reported. A case of a 51-year-old kidney transplant recipient diagnosed with EBV-SMT is reported together with a review of the literature.

Abstract
Leiomyosarcoma is a rare Epstein-Barr virus (EBV)-related complication of solid-organ transplantation. We report the case of a 19-year-old woman with cystic fibrosis who presented with protracted headaches 15 months after an EBV-mismatched bilateral sequential lung transplant. A parasagittal lesion was found on cranial magnetic resonance imaging; surgical resection revealed a leiomyosarcoma. We discuss treatment options of what is, to our knowledge, the first described case of a cranial leiomyosarcoma in a lung transplant recipient.
