First incidence of extrarenal wilms tumor within the spinal canal in the adult population: a novel case report and literature review. BMC Urol 2024; 24:119. [PMID: 38858693 PMCID: PMC11163749 DOI: 10.1186/s12894-024-01508-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Accepted: 06/04/2024] [Indexed: 06/12/2024] Open
Abstract
BACKGROUND Wilms tumor (WT), also known as nephroblastoma, is rare in adults, accounting for merely 3% of all nephroblastomas or 0.2 cases per million individuals. Extrarenal Wilms tumor (ERWT) emerges outside the renal boundaries and comprises 0.5 to 1% of all WT cases, with even rarer incidences in adults. Oncogenic mutations associated with ectopic nephrogenic rests (NR) may contribute to ERWT development. Diagnosis involves surgical resection and pathology examination. Due to scarce cases, adults often rely on pediatric guidelines. We thoroughly searched PubMed, Scopus, and Web of Science databases to establish our case's uniqueness. To the best of our knowledge, this is the first documented incidence of extrarenal Wilms tumor within the spinal canal in the adult population. CASE PRESENTATION A 22-year-old woman with a history of congenital lipo-myelomeningocele surgery as an infant presented with a 6-month history of back pain. This pain gradually resulted in limb weakness, paraparesis, and loss of bladder and bowel control. An MRI showed a 6 × 5 × 3 cm spinal canal mass at the L4-S1 level. Consequently, a laminectomy was performed at the L4-L5 level to remove the intramedullary tumor. Post-surgery histopathology and immunohistochemistry confirmed the tumor as ERWT with favorable histology without any teratomatous component. CONCLUSION This report underscores the rarity of extrarenal Wilms tumor (ERWT) in adults, challenging conventional assumptions about its typical age of occurrence. It emphasizes the importance of clinical awareness regarding such uncommon cases. Moreover, the co-occurrence of spinal ERWTs and a history of spinal anomalies warrants further investigation.

Teratoma-associated and so-called pure Wilms tumour of the ovary represent two separate tumour types with distinct molecular features. Histopathology 2024; 84:683-696.

Abstract
AIMS Ovarian Wilms tumour (WT)/nephroblastoma is an extremely rare neoplasm that has been reported to occur in pure form or as a component of a teratomatous neoplasm. We hypothesized that teratoma-associated and pure ovarian WT may represent different tumour types with diverging molecular backgrounds. To test this hypothesis, we comprehensively characterized a series of five tumours originally diagnosed as ovarian WT. METHODS AND RESULTS The five cases comprised three teratoma-associated (two mature and one immature) and two pure WTs. Two of the teratoma-associated WTs consisted of small nodular arrangements of "glandular"/epithelial structures, while the third consisted of both an epithelial and a diffuse spindle cell/blastemal component. The pure WTs consisted of "glandular" structures, which were positive for sex cord markers (including inhibin and SF1) together with a rhabdomyosarcomatous component. The two pure WTs harboured DICER1 pathogenic variants (PVs), while the three associated with teratomas were DICER1 wildtype. Panel-based DNA sequencing of four of the cases did not identify PVs in the other genes investigated. Analysis of the HA19/IGF2 imprinting region showed retention of imprinting in the pure WTs but loss of heterozygosity with hypomethylation of the ICR1 region in two of three teratoma-associated WTs. Furthermore, copy number variation and clustering-based whole-genome DNA methylation analyses identified divergent molecular profiles for pure and teratoma-associated WTs. CONCLUSION Based on the morphological features, immunophenotype, and molecular findings (DICER1 PVs, copy number, and DNA methylation profiles), we suggest that the two cases diagnosed as pure primary ovarian WT represent moderately to poorly differentiated Sertoli Leydig cell tumours (SLCTs), while the tumours arising in teratomas represent true WTs. It is possible that at least some prior cases reported as pure primary ovarian WT represent SLCTs.

Cancers (Basel) 2023; 15:cancers15092563. [PMID: 37174029 PMCID: PMC10177564 DOI: 10.3390/cancers15092563] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 04/07/2023] [Accepted: 04/12/2023] [Indexed: 05/15/2023] Open
Abstract
Wilms Tumor (WT) is one of the most common renal tumors in the pediatric population. Occasionally, WT can primarily develop outside the kidneys (Extra-Renal Wilms Tumor, ERWT). Most pediatric ERWTs develop in the abdominal cavity and pelvis, whereas the occurrence of this tumor in other extra-renal sites represents a minor part of ERWT cases. In addition to describing a case of spinal ERWT (associated with spinal dysraphism) in a 4-year boy (to add a further clinical experience on this very rare pediatric tumor), we performed a case-based systematic literature review on pediatric ERWT. We retrieved 72 papers providing enough information on the diagnosis, treatment, and outcomes of 98 ERWT pediatric patients. Our research highlighted that a multimodal approach involving both chemotherapy and radiotherapy, after partial or complete tumor resection in most cases, was typically used, but there is no standardized therapeutic approach for this pediatric malignancy. However, this tumor may be potentially treated with a better success rate if the diagnostic confirmation is not delayed, the mass can be totally resected, and an appropriate and, possibly, tailored multimodal treatment can be promptly established. In this regard, an international agreement on a unique staging system for (pediatric) ERWT is definitely needed, as well as the development of international research, which may be able to gather several children diagnosed with ERWT and, possibly, lead to clinical trials which should also include developing countries.

Abstract
Primary extrarenal Wilms tumors are rare neoplasms that are presumed to arise from metanephric or mesonephric remnants outside of the kidney. Their pathogenesis is debated but has not been studied, and there are no reports of genomic descriptions of extrarenal Wilms tumors. We describe a diffusely anaplastic extrarenal Wilms tumor that occurred in the lower abdomen and upper pelvis of a 10-year-old boy. In addition to the clinical, histopathologic, and radiologic features, we describe the cytogenetic changes and exomic profile of the tumor. The tumor showed loss of the tumor suppressor AMER1, loss of chromosome regions 1p, 16q, and 22q, gain of chromosome 8, and loss of function TP53 mutation-findings known to occur in renal Wilms tumors. This is the first description of the exomic profile of a primary extrarenal Wilms tumor. Our data indicate that primary extrarenal Wilms tumors may follow the same pathogenetic pathways that are seen in renal Wilms tumors. Finally, we describe the establishment of first ever tumor models (primary cell line and patient-derived xenograft) from an extrarenal Wilms tumor.

Abstract
Primary extrarenal Wilms tumor of the gynecologic tract is extremely rare with scattered case reports occurring in the ovary, uterine corpus and cervix. Only 9 cases of primary ovarian Wilms tumor have been reported to date. Here, we provide an extensive literature review and describe 2 patients with ovarian Wilms tumor: a 36-yr-old female (patient 1) and a 16-yr-old female (patient 2), both presenting with abdominal pain and suspected ovarian torsion. They were each found to have unilateral ovarian masses measuring >15 cm in size which were removed by unilateral salpingo-oophorectomy. Microscopically, the tumors exhibited the typical triphasic histology of Wilms tumor. In addition, the tumor from patient 1 contained elements of mature cystic teratoma, while an extensive rhabdomyosarcomatous component was identified in patient 2. Both tumors were diffusely and strongly positive for WT1 with variable staining for other biomarkers. The cases were diagnostically challenging and referred to our center for an expert opinion. Teratoid Wilms tumor in patient 1 is the second reported case of ovarian Wilms tumor arising in association with teratoma. Recognition of primary ovarian Wilms tumor requires a high index of suspicion and exclusion of other entities based on tumor morphology and immunohistochemical studies.

Abstract
Extrarenal Wilms' tumor of the ovary is a very rare tumor likely derived from embryonic mesonephros. We present the first reported case of a teratoid extrarenal Wilms' tumor of the ovary with a short review of the existing literature. In the case, a 26-year-old woman presented with back pain and was found to have a dermoid cyst; three years later, she presented again, now pregnant, with severe abdominal pain. She was diagnosed with an immature teratoma consisting of a Wilms' tumor (immature component) arising within a mature teratoma and treated exclusively with surgery and surveillance. The recovery from surgery was uneventful and the patient remains without evidence of disease with eleven months of follow-up.

Abstract
Wilms' tumor is the most common malignant solid tumor of the kidneys in children. Extrarenal Wilms' tumor is extremely rare. Herein, we report an 8-month-old boy with a chief complaint of frequent micturition and dysuria for 10 days. Physical examination and ultrasonography evaluation revealed simultaneous involvement of neoplasms in the left kidney and the bladder. Following excision of the masses, both were identified as Wilms' tumor by histopathology and immunohistochemistry. The two neoplasms are presumed to have developed independently because of the different pathological manifestation.

Abstract
Nephroblastomas (Wilms' tumour) are the most common solid malignancies in childhood, but extra-renal Wilms' tumours are rare entities, and the diagnosis is made only after surgical intervention. However, the embryogenesis and the exact mechanism of occurrence of primary ERWTs is controversial, thereby presenting a number of unanswered questions of great theoretical interests. We present three well-proven cases of extra-renal Wilms' tumour together with a review of the literature based on its histogenesis, its behaviour and its management policies.

Abstract
BACKGROUND Extrarenal Wilms' tumors (EWT) are rare. In the female genital tract, only 15 cases (6 adults, 9 children) of EWT have been reported. A case of uterine Wilms' tumor in an adult is presented with a review of the literature. CASE A 44-year-old woman presented with a bleeding polypoid cervical mass. Biopsy revealed EWT. She was surgically staged, received chemotherapy, and is without evidence of disease at 1 year follow-up. CONCLUSIONS Prognosis and treatment of EWT may differ by location and patient age. Literature review of uterine Wilms' tumor reveals favorable outcome with (1) focal disease confined to the uterus and (2) adequate surgery, including hysterectomy. The National Wilms' Tumor Study Group recommends adjuvant chemotherapy for all EWT. Radiation may be reserved for patients with residual, metastatic and/or recurrent disease.

Abstract
Um caso de tumor de Wilms extra-renal de localização retroperitoneal em uma paciente do sexo feminino de dois anos de idade é apresentado, associado a revisão de literatura. Foram realizados exames de radiografia simples do abdome, urografia excretora, ultra-sonografia e tomografia computadorizada sem e com contraste, que evidenciaram a presença de massa retroperitoneal adjacente ao rim direito. A paciente foi submetida a intervenção cirúrgica, com ressecção de toda a massa, sendo o diagnóstico de tumor de Wilms confirmado com exame anatomopatológico. O tumor de Wilms extra-renal é uma entidade extremamente rara e maligna, descrito na literatura principalmente sob a forma de relato de caso. Pode ocorrer no retroperitônio, útero e ovários, canal inguinal, testículos, pele, e até mesmo no tórax. O mecanismo exato que poderia explicar a ocorrência deste tumor em tecido extra-renal não foi bem estabelecido ainda. O diagnóstico é feito através do estudo anatomopatológico da lesão, geralmente após intervenção cirúrgica.

Abstract
Heterotopic renal tissue (HRT) in the wall of the colon is a very rare occurrence, with only five cases published. Our patient is only the second patient reported to have this abnormality in the absence of sirenomelia. We describe colonic HRT in a child, associated with multiple congenital anomalies. The congenital abnormalities were of the VACTERL type, accompanied by valvular cardiac anomalies that were clinically diagnosed as Shone syndrome. The HRT was not apparent clinically or grossly. Microscopically, multifocal islands of renal tissue consisting of glomeruli, cystically dilated tubules, and blastema were seen in all layers of the bowel, and simulated "cystic partially differentiated nephroblastoma." Our case provides further support to the belief that VACTERL association and sirenomelia represent related entities.
