Abstract
BACKGROUND Primary uterine alveolar soft part sarcoma (ASPS) is a rare, indolent mesenchymal malignancy with less than 40 patients documented in the literature. CASE We report an example of ASPS in a 61-year-old postmenopausal woman. Macroscopically, the uterus showed multiple nodular masses. Microscopic examination revealed tumor arranged in nests and alveolar pattern. The tumor cells were moderately to markedly pleomorphic, epithelioid to polygonal, with eccentrically placed nuclei, vesicular chromatin, prominent macro-nucleoli, and moderate to abundant eosinophilic cytoplasm. PAS-positive and diastase-resistant intracytoplasmic crystals were also seen in some tumor cells. On immunohistochemistry, the tumor cells showed diffuse positivity for vimentin and nuclear positivity for TFE3, a surrogate marker for ASPS. These were negative for SMA, desmin, CD10, h-caldesmon, cyclin D1, EMA, Melan A, and CD34. SMARCB1 expression was retained. Based on the histopathology and IHC, a final diagnosis of uterine ASPS was rendered. CONCLUSIONS Knowledge of the characteristic histopathologic and immunohistochemical features can help accurately diagnose such rare tumors. Knowledge of the characteristic histopathologic and immunohistochemical features can help accurately diagnose such rare sarcoma in an uncommon site with an unusual age.

Abstract
Alveolar soft part sarcoma is a rare neoplasm of uncertain histogenesis that belongs to a newly defined category of ultra-rare sarcomas. The neoplasm is characterized by a specific chromosomal translocation, der (17) t(X; 17)(p11.2;q25), that results in ASPSCR1-TFE3 gene fusion. The natural history of alveolar soft part sarcoma describes indolent behaviour with slow progression in deep soft tissues of the extremities, trunk and head/neck in adolescents and young adults. A high rate of detection of distant metastasis at presentation has been reported, and the most common metastatic sites in decreasing order of frequency are the lung, bone and brain. Complete surgical resection remains the standard treatment strategy, whereas radiotherapy is indicated for patients with inadequate surgical margins or unresectable tumours. Although alveolar soft part sarcoma is refractory to conventional doxorubicin-based chemotherapy, monotherapy or combination therapy using tyrosine kinase inhibitors and immune checkpoint inhibitors have provided antitumor activity and emerged as new treatment strategies. This article provides an overview of the current understanding of this ultra-rare sarcoma and recent advancements in treatments according to the clinical stage of alveolar soft part sarcoma.

Abstract
Alveolar soft part sarcoma (ASPS) is a rare type of soft tissue sarcoma that typically affects adolescents and young adults, though it can occur at any age. We report a case of ASPS of the tongue, which is extremely rare at this location. The patient presented with a polypoidal lesion on the tongue, a biopsy of which showed granular and alveolar morphology. A definitive diagnosis was not rendered due to limited tissue. The case was discussed with the treating surgeon, and excision was recommended with clear margins. Excision of the lesion showed typical ASPS. A TFE-3 immunohistochemical stain was done, which showed strong immunoreactivity, thereby confirming the diagnosis of ASPS. This tumour is rare, and its presence in the tongue makes it extremely infrequent.

Abstract
Alveolar soft part sarcoma is a rare soft tissue neoplasm that accounts for approximately 1% of all sarcomas and is usually identified in the extremities in adults. The occurrence of alveolar soft part sarcoma in the orbit is extremely rare, estimated at approximately 5% – 15% among all cases of alveolar soft part sarcoma . Here, we present a case of 29-year-old woman with orbital alveolar soft part sarcoma. We describe the magnetic resonance and F-18 2-fluoro-2-deoxy-D-glucose-position emission tomography/computed tomography findings of this case. This young woman had a spindle-shaped mass. A higher signal compared to the extraocular muscle on T1-weighted images, numerous flow voids on T2-weighted images, and intense enhancement could be key findings of this disease.

Abstract
Background Alveolar soft part sarcoma (ASPS) is a translocation-associated soft-tissue tumor resistant to conventional cytotoxic agents. This report aims to compare the efficacy of anlotinib versus pazopanib as targeted monotherapy in metastatic ASPS and to determine the impact of drug dosage reduction on disease control. Methods Sixteen and 31 patients with metastatic ASPS were respectively treated with anlotinib and pazopanib monotherapy at a single institution. Objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were retrieved and compared between both therapeutic arms. Adverse events (AEs) within each group were recorded. Kaplan-Meier survivorship curves computed the impact of drug dosage reduction on PFS. Results The anlotinib group showed an ORR of 31.2%, compared to 35.5% in the pazopanib arm (P=0.772). Median PFS was 23.6 months [95% confidence interval (CI), 16.2-31.0 months] in patients treated with anlotinib, but dropped to 13.7 months (95% CI, 10.8-16.7 months) in those managed with pazopanib (P=0.023). One (6.3%) patient on anlotinib and 11 (35.5%) on pazopanib developed AEs requiring drug dosage reduction (P=0.029), which significantly reduced patients' PFS in the latter setting (10.5 vs. 15.8 months, P=0.012). In patients without dosage reduction, anlotinib showed a bordering advantage than pazopanib on median PFS (24.5 vs. 15.8 months, P=0.112). Conclusions Compared to pazopanib, anlotinib yielded longer PFS and lower incidence of AEs in ASPS patients. Drug dosage reduction was more frequently encountered with the former agent and affected the disease control.

Abstract
BACKGROUND Alveolar soft part sarcoma is a rare, histologic subtype of soft tissue sarcoma that remains poorly defined. We aimed to describe patient characteristics and treatment patterns and to examine factors associated with survival for patients with alveolar soft part sarcoma. METHODS After identifying patients with alveolar soft part sarcoma in the National Cancer Database, we recorded their clinicopathologic characteristics. Univariable log-rank survival analysis and Cox proportional hazards model were employed. For context, survival comparisons were included for patients with other sarcoma subtypes. RESULTS Overall, 293 patients with alveolar soft part sarcoma were identified. Interestingly, patients with head and neck tumors were least likely to present with distant disease (40%, P = .025). The majority of patients underwent resection (n = 183, 63%). Among those, no predictors of lesser survival were identified other than the presence of metastases (hazard ratio 6.04, P ≤ .001). Patients with stage IV alveolar soft part sarcoma who underwent resections experienced improved survival relative to similar patients with more common subtypes of soft tissue sarcomas (P ≤ .001). CONCLUSION Alveolar soft part sarcoma is exceedingly rare, and patients often present with metastases. Primary tumors can occur anywhere in the body, and location impacts the rates of metastases at presentation. Resection is associated with a favorable survival advantage when compared to other, more common histologic subtypes of soft tissue sarcomas.

Abstract
BACKGROUND Recent years have brought the dynamic development of a new method of cancer treatment: immunotherapy. Monoclonal antibodies blocking the programmed death receptor 1 (PD-1) are now widely used in the treatment of several malignancies: melanoma, lung, head and neck cancer, among others. The therapeutic benefit of immunotherapy in soft tissue sarcoma (STS) has not yet been proven. The exception is results obtained in the treatment of a rare STS subtype alveolar soft part sarcoma (ASPS). CASE REPORT We describe a case of a man with a diagnosis of metastatic ASPS in whom the use of immunotherapy with nivolumab resulted in excellent long-term clinical benefit and a pathologically confirmed complete response. CONCLUSION There are strong indications that immunotherapy may become the next important treatment method of ASPS.

Abstract
RATIONALE Alveolar soft part sarcoma (ASPS) is a rare malignant soft tissue neoplasm with controversial histogenesis. ASPS accounts for 0.5% to 1% of all soft tissue sarcomas. Because of its rarity, ASPS is easily misdiagnosed, increasing the risk of incorrect treatment. PATIENT CONCERNS A 6-year-old female patient presented with a history of a 2.0 × 2.5 × 3.0-cm mass in the deep soft tissues of her right lower extremity. DIAGNOSES Histopathological features indicated the diagnosis of ASPS. Microscopically, a diffuse arrangement of tumor cells or pseudoalveolar architectures separated by thin and well-vascularized fibrous septa were observed. Immunohistochemical staining of the tumor cells indicated positivity for transcription factor E3, myogenic determination factor 1, and periodic acid-Schiff-diastase (PAS-D) and showed a Ki-67 proliferating index of approximately 20%. INTERVENTIONS The patient underwent enlarged resection of the tumor and was treated with radiotherapy. OUTCOMES During the 3-year follow-up, the patient has remained in good condition, with no symptom recurrence, distant metastatic spread, or significant toxicity during or after treatment. The patient remains under regular surveillance. LESSONS Its low incidence, lack of characteristic clinical manifestations, and atypical location often lead to ASPS misdiagnosis and subsequent incorrect treatment. Nuclear expression of transcription factor E3 is of diagnostic value for ASPS. At present, there is no consensus on the treatment for ASPS. In-depth pathological analysis is needed to better understand the characteristics of this tumor.

Abstract
BACKGROUND Alveolar soft-part sarcoma (ASPS), a rare vascular sarcoma with a clinically indolent course, frequently presents with metastases. Vascular endothelial growth factor (VEGF) is a promising therapeutic target. In a phase-II trial of the VEGF receptor inhibitor cediranib for adults with ASPS, the partial response (PR) rate (response evaluation criteria in solid tumors [RECIST] v1.0) was 35% (15/43; 95% confidence interval: 21-51%). We evaluated cediranib in the pediatric population. PROCEDURE Patients <16 years old with metastatic, unresectable ASPS received cediranib at the pediatric maximum tolerated dose of 12 mg/m2 (≈70% of the fixed adult phase-II dose orally daily). Tumor response was assessed every two cycles (RECIST v1.0). A Simon two-stage optimal design (target response rate 35%, rule out 5%) was used. RESULTS Seven patients (four females), with a median age of 13 years, (range 9-15), were enrolled on stage 1. The most frequent grade 2 or 3 adverse events were neutropenia, diarrhea, hypertension, fatigue, and proteinuria. The best response was stable disease (SD) (median cycle number = 34). Three patients were removed from the study treatment for disease progression (cycles 4, 5, and 36). Five of seven patients had SD for ≥14 months. Two patients with SD remain on study (34-57+ cycles). CONCLUSIONS Cediranib did not reach the target response rate in this small pediatric cohort, in contrast to the adult 35% PR rate. The pediatric dosing was 30% lower compared to the adult dosing, which may have contributed to response differences. Prolonged SD was observed in five patients, but given the indolent nature of ASPS, SD cannot be clearly attributed to cediranib. Cediranib has an acceptable safety profile.

Abstract
RATIONALE Alveolar soft part sarcoma (ASPS) is a very rare soft tissue sarcoma. ASPS often occurs in deep soft tissues of the lower extremities, and develops into metastatic diseases. Chemotherapy is considered to be ineffective in patients with ASPS, which constitutes a very important clinical challenge. The strategy for ASPS treatment still requires clarification in order to improve survival outcome. Patients concerns: A 19-year-old female patient presented with a 5-year history of painless lump in the left knee and 4-day cough. Her previous medical history was unremarkable. Menstruation and family history were also normal in this patient, whose physical examination and laboratory test results showed no abnormalities. DIAGNOSIS ASPS was confirmed by clinical manifestations, radiological data and pathological diagnosis of the biopsy of left knee. INTERVENTIONS AND OUTCOMES This patient received circulating tumor DNA detection and only a mutation of the SMARCA4 gene was detected. The patient received sunitinib treatment (37.5 mg once daily) for 15 months and showed partial regression of lung metastatic lesions and stabilization of brain metastases. She achieved 15 months of progression free survival. CONCLUSIONS Sunitinib is effective for the treatment of advanced ASPS with lung and brain metastases. The current patient had long-term progression free survival under sunitinib administration.

Abstract
Lessons Learned. Pazopanib shows a modest efficacy in metastatic alveolar soft part sarcoma. Clinical outcomes were comparable to those in previous studies using antiangiogenic drugs. Further prospective studies evaluating the benefit of pazopanib in alveolar soft part sarcoma with a larger sample are warranted to validate results.
Background. Alveolar soft part sarcoma (ASPS) is a rare mesenchymal malignant tumor characterized by an unbalanced translocation, t(X;17)(p11.2;q25), which leads to the fusion of ASPSCR1 to the TFE3 transcription factor. Because this results in the upregulation of angiogenesis‐related transcripts, antiangiogenic drugs have been used in ASPS patients. Methods. This open‐label, single‐arm, multicenter, investigator‐initiated phase II trial was designed to evaluate efficacy and safety of pazopanib 800 mg once daily in patients with metastatic ASPS. The primary endpoint was investigator‐assessed overall response rate (ORR), and secondary endpoints were toxicity, progression‐free survival (PFS), and overall survival (OS). 68Ga‐RGD (Arg‐Gly‐Asp) positron emission tomography (PET) scan and gene expression profiling using NanoString platform were performed for biomarker analysis. Results. Six patients with histologically confirmed metastatic ASPS were enrolled between December 2013 and November 2014. Among six patients, one achieved a partial response (PR) (ORR 16.7%) and five patients showed stable disease (SD). With a median follow‐up of 33 months (range 18.7–39.3 months), median PFS was 5.5 months (95% confidence interval [CI] 3.4–7.6 months), and median OS was not reached. There were no severe toxicities except one patient with grade 3 diarrhea. Conclusion. Pazopanib showed modest antitumor activity with manageable toxicities for patients with metastatic ASPS.

Abstract
RATIONAL Alveolar soft part sarcomas (ASPSs) with multiple brain metastases in pregnancy is a rare entity. PATIENT CONCERNS We report our experience with a 19-year-old pregnant woman who presented with intermittent headaches and vomiting at 38 weeks gestation. DIAGNOSES The patient was initially diagnosed as brain metastasis according to computed tomography and magnetic resonance imaging (MRI) imaging. INTERVENTIONS Cesarean section and craniotomy (complete resection of both brain metastatic lesions) was performed sequentially. OUTCOMES A healthy baby girl was delivered safely and no neonatal malformations were found. Histological analysis confirmed the diagnosis of ASPS. Follow-up MRI performed 10 months after surgery revealed no residual tumor or signs of recurrence. LESSONS We report a case of ASPS with multiple brain and lung metastases in a pregnant woman. We recommend timely MRI examination for diagnosis and have discussed the approach to the treatment of pregnant women with brain metastasis.

Abstract
A 20-year-old woman with a perineal alveolar soft part sarcoma was referred to our hospital. MRI showed that an irregular oval tumor occupied the perineum. The tumor was contiguous to the vagina, rectum, levator muscle, and pubis and was diagnosed as alveolar soft part sarcoma by transvaginal biopsy. Laparoscopy-assisted total pelvic exenteration combined with a pubic resection was performed, and an R0 resection with a wide margin was achieved. It is well known that only R0 resection improves the outcome of patients with localized alveolar soft part sarcoma. In this case, the perineal manipulation was difficult because the tumor was huge and had a rich blood flow. Massive bleeding occurred during the perineal manipulation. However, we kept the operative field dry thanks to minimal intraoperative blood loss during the laparoscopic phase. The laparoscopic approach might be advantageous for such a demanding surgical procedure for tumors in the distal pelvis and perineum.

Abstract
The aim of the present study was to identify the target genes of cediranib and the associated signaling pathways in alveolar soft part sarcoma (ASPS). A microarray dataset (GSE32569) was obtained from the Gene Expression Omnibus database. The R software package was used for data normalization and screening of differentially expressed genes (DEGs). The Database for Annotation, Visualization and Integrated Discovery was used to perform Gene Ontology analysis. Gene Set Enrichment Analysis was performed to obtain the up- and downregulated pathways in ASPS. The Distant Regulatory Elements of co-regulated genes database was used to identify the transcription factors (TFs) that were enriched in the signaling pathways. A protein-protein interaction (PPI) network was constructed using the Search Tool for the Retrieval of Interacting Genes/Proteins database and was visualized using Cytoscape software. A total of 71 DEGs, including 59 upregulated genes and 12 downregulated genes, were identified. Gene sets associated with ASPS were enriched primarily in four signaling pathways: The phenylalanine metabolism pathway, the mitogen-activated protein kinase (MAPK) signaling pathway, the taste transduction pathway and the intestinal immune network for the production of immunoglobulin A. Furthermore, 107 TFs were identified to be enriched in the MAPK signaling pathway. Certain genes, including those coding for Fms-like tyrosine kinase 1, kinase insert domain receptor, E-selectin and platelet-derived growth factor receptor D, that were associated with other genes in the PPI network, were identified. The present study identified certain potential target genes and the associated signaling pathways of cediranib action in ASPS, which may be helpful in understanding the efficacy of cediranib and the development of new targets for cediranib.

Abstract
Background Alveolar soft part sarcoma (ASPS) is a rare entity of soft tissue malignancies with uncommon spinal involvements. Surgical management should be the best choice of cure. Methods Five patients with spinal ASPS were interviewed retrospectively, where data was collected. The relevant literatures were also systematically examined. Thereafter, patient and surgical data were obtained and pooled for prognostic analysis. Results A total of five patients with eight surgeries were reviewed retrospectively, and three patients previously reported were also included. All patients were surgically treated, where five of them underwent additional adjuvant therapies such as chemotherapy, radiotherapy, and targeted therapy in order to manage their local and/or systematic diseases. One patient was lost in follow-up. For the remaining seven patients, the mean follow-up period was 19.7 ± 8.8 months, two succumbed to disease while five were alive at the time of the study. Conclusions Surgical management is shown to be the most important and the most effective treatment strategy for spinal ASPS, whereas adjuvant therapies made little impact. The prognostic factors for spinal ASPS are primary or metastatic lesions, neurological status, disease progression, systematic conditions, and resection approaches.

Objectives A 36-year-old Asian man was referred to our hospital with cardiac metastasis. He had a history of alveolar soft part sarcoma and initially underwent resection in 2005. Methods After exposing the tumor by thoracotomy, cryoablation was performed under ultrasound guidance. This treatment was combined with iodine-125 seed implantation to treat the cardiac metastasis. Results The patient had an uneventful recovery, and his cardiac function shows no obvious abnormalities. Imaging techniques suggest that cardiac metastasis was well controlled, and the patient is still alive 12 months after treatment. Conclusions Tumor cryoablation, combined with iodine seed implantations, may be regarded as a means of palliative treatment.

Abstract
We report a case of bladder alveolar soft part sarcoma in an 18-year-old Thai male patient who had been treated with testicular radiation and systemic chemotherapy for acute lymphoblastic leukemia with testicular relapse. He presented with recurrent dysuria and gross hematuria. Cystoscopy revealed a 2-centimeter irregular sessile mass at the bladder base adjacent to left ureteral orifice. Transurethral resection of the tumor was performed. The histopathological diagnosis was alveolar soft part sarcoma. Chest and abdominal computed tomography showed no evidence of metastasis. He was treated with partial cystectomy and left ureteral reimplantation with negative surgical margin. No evidence of recurrence was found during a 28-month follow-up period with surveillance cystoscopy and computed tomography of the chest and abdomen.

Abstract
BACKGROUND Alveolar soft part sarcoma (ASPS) is a relatively rare malignant tumor and early diagnosis and appropriate treatment for ASPS are essential for a good prognosis. PURPOSE To retrospectively review the clinical presentation and computed tomography (CT) and magnetic resonance imaging (MRI) findings of ASPS so as to improve the accuracy of imaging diagnosis. MATERIAL AND METHODS Fourteen patients with pathologically proven ASPS were enrolled. Their clinical and imaging findings were retrospectively reviewed. RESULTS The median age of the patients was 29 years (range, 13-37 years). Most tumors were located in the soft tissues of the trunk and lower limbs. The median maximal diameter of the masses was 91 mm. Thirteen masses presented with ovoid or irregular shapes. Eleven masses had less clear boundaries. Compared with the adjacent muscles, the masses were isodense or hypodense on CT, hypo-, iso-, or hyperintense on T1-weighted images, and heterogeneous hyperintense on T2-weighted images. Intense enhancement was seen after contrast agent administration, with prominent intra- or peri-tumoral feeders on CT or flow voids on MRI. By the end of the last follow-up, 13 patients had distant metastasis and three patients had local recurrence. CONCLUSION ASPS should be included in the differential diagnosis when a bulky, heterogeneous soft tissue mass in the trunk and the lower limbs with intense enhancement after contrast administration and prominent intra- or peri-tumoral feeders on CT or flow voids on MRI is seen, particularly in young patients.

Alveolar soft part sarcoma of lung: report of a unique case with emphasis on diagnostic utility of molecular genetic analysis for TFE3 gene rearrangement and immunohistochemistry for TFE3 antigen expression. Diagn Pathol 2015; 10:160.

Abstract
Alveolar soft part sarcoma (ASPS) is a rare, malignant mesenchymal tumor of distinctive clinical, morphologic, ultrastructural, and cytogenetical characteristics. It typically arises in the extremities of adolescents and young adults, but has also been documented in a number of unusual sites, thus causing diagnostic confusions both clinically and morphologically. The molecular signature of ASPS is a specific der(17)t(X;17)(p11.2;q25) translocation, which results in the fusion of TFE3 transcription factor gene at Xp11.2 with ASPL at 17q25. Recent studies have shown that the ASPL-TFE3 fusion transcript can be identified by reverse-transcriptase polymerase chain reaction analysis and TFE3 gene rearragement can be detected using a dual-color, break apart fluorescence in situ hybridization assay in paraffin-embedded tissue, and the resultant fusion protein can be detected immunohistochemically with antibody directed to the carboxy terminal portion of TFE3. Herein, we report a unique case of ASPS presenting as an asymptomatic mass in the lung of a 48 year-old woman without evidence of a primary soft tissue tumor elsewhere at the time of initial diagnosis. To the best of our knowledge, this is the third report of such cases appearing in the English language literature to date. We emphasize the differential diagnoses engendered by ASPS including a series of tumors involving the lung that have nested and alveolar growth patterns, and both clear and eosinophilic cytoplasm, and demonstrate the utility of molecular genetic analysis for TFE3 rearrangement and immunohistochemistry for TFE3 antigen expression for arriving at accurate diagnosis.

Abstract
INTRODUCTION Alveolar soft part sarcoma (ASPS) commonly arises in the soft tissue of the lower extremities. Primary bone involvement is rare. METHODS/RESULTS We report a 23-year-old male who presented with pathologic fracture of the clavicle, and diagnosis of clavicular ASPS. Workup demonstrated a lumbar meningeal mass, also involving the vertebral bodies. CONCLUSIONS Few cases of primary bone ASPS have been identified. Most common primary bone involvement includes the fibula, ilium and tibia. Likewise, meningeal involvement is quite rare. In summary, primary bone ASPS is rare and may involve the clavicle. Meningeal involvement is likewise rare, and presumably represents metastatic spread.

Abstract
PURPOSE Alveolar soft part sarcoma (ASPS) is a rare, highly vascular tumor, for which no effective standard systemic treatment exists for patients with unresectable disease. Cediranib is a potent, oral small-molecule inhibitor of all three vascular endothelial growth factor receptors (VEGFRs). PATIENTS AND METHODS We conducted a phase II trial of once-daily cediranib (30 mg) given in 28-day cycles for patients with metastatic, unresectable ASPS to determine the objective response rate (ORR). We also compared gene expression profiles in pre- and post-treatment tumor biopsies and evaluated the effect of cediranib on tumor proliferation and angiogenesis using positron emission tomography and dynamic contrast-enhanced magnetic resonance imaging. RESULTS Of 46 patients enrolled, 43 were evaluable for response at the time of analysis. The ORR was 35%, with 15 of 43 patients achieving a partial response. Twenty-six patients (60%) had stable disease as the best response, with a disease control rate (partial response + stable disease) at 24 weeks of 84%. Microarray analysis with validation by quantitative real-time polymerase chain reaction on paired tumor biopsies from eight patients demonstrated downregulation of genes related to vasculogenesis. CONCLUSION In this largest prospective trial to date of systemic therapy for metastatic ASPS, we observed that cediranib has substantial single-agent activity, producing an ORR of 35% and a disease control rate of 84% at 24 weeks. On the basis of these results, an open-label, multicenter, randomized phase II registration trial is currently being conducted for patients with metastatic ASPS comparing cediranib with another VEGFR inhibitor, sunitinib.

Abstract
Alveolar Soft Part Sarcoma (ASPS) is a very rare type of soft tissue sarcoma. Its cell of origin is unclear. It usually presents in the second to fourth decade of life. The most common reported sites of ASPS are the lower extremities, the head and the neck. Because of the rarity of this disease, there is no standard treatment plan. Surgical excision with negative margins is considered as the treatment of choice. We are reporting a rare presentation of ASPS as a male breast lump.

Abstract
Alveolar soft part sarcoma (ASPS) is a rare neoplasm of uncertain cell of origin. Known to occur in adolescents and young adults, this tumor usually involves the muscles and deep soft tissues of the extremities and trunk. Orbital localization is rare and not yet subjected to cytological assessment, as per our literature search. We present here two cases of ASPS diagnosed by aspiration cytology, one in the orbit and the other in the lower extremity. The cells displayed abundant clear to finely vacuolated cytoplasm, often with disrupted margins and flowing of the cytoplasmic material; prominent nucleoli and scattered bare nuclei were also seen in the background. Two close cytological differential diagnoses include metastatic renal cell carcinoma and paraganglioma. Intracytoplasmic periodic acid schiff (PAS) positive, diastase-resistant, needle-shaped crystals and corresponding rhomboid crystals with regular lattice pattern on ultrastructure are the hallmarks of this neoplasm. Due to its slowly progressive clinical course and poor outcome, preoperative diagnosis of ASPS through fine-needle aspiration cytology may be essential for deciding therapy, especially in rare and difficult locations like orbit, where adjuvant radiation may not be possible.

Abstract
Alveolar soft part sarcoma (ASPS) is a rare malignant soft-tissue neoplasm of unknown histogenesis. The two main sites of occurrence are the lower extremities in adults and the head and neck in children. We report the first case of pleural ASPS occurring in a 58-yr-old man who presented with progressive dyspnea. A computed tomographic scan of the thorax revealed a large enhancing pleural mass with pleural effusion in the left hemithorax. Wide excision of the pleural mass was performed. Histologically, the tumor consisted of organoid nests of large polygonal cells, the cytoplasm of which had eosinophilic and D-PAS positive granules. Immunohistochemical staining showed that the tumor cell nuclei were positive for transcription factor 3 (TFE3). The pleural ASPS with multiple bone metastases recurred 1 yr after surgery and the patient died of acute pulmonary embolism 1.5 yr after diagnosis.

Abstract
After a brief discussion of the rarity of soft tissue sarcomas in children and of the limited ability of magnetic resonance imaging to provide a tissue diagnosis, this article discusses the incidence, presentation, treatment, prognosis, and imaging characteristics of the more common and unusual pediatric soft tissue sarcomas. It begins with extensive discussion of rhabdomyosarcoma, synovial sarcoma, and congenital/infantile fibrosarcoma. It then presents a more abbreviated discussion of uncommon tumors such as alveolar soft part sarcoma, epithelioid sarcoma, extraosseous Ewing's sarcoma, granulocytic sarcoma, hemangiopericytoma, liposarcoma, malignant fibrous histiocytoma, malignant peripheral nerve sheath tumor, and undifferentiated sarcoma.

Abstract
Pure sarcomas of the uterine corpus are uncommon, constituting less than 3% of all malignancies at this site, and most of them are leiomyosarcomas and endometrial stromal sarcomas. Rare histotypes of homologous sarcomas and heterologous sarcomas are occasionally encountered, and the absence of significant accumulated experience with these histotypes at this location may potentially raise diagnostic and patient management difficulties. In this article, the clinicopathologic attributes of all earlier reported sarcomas of the uterine corpus other than leiomyosarcomas and endometrial stromal sarcomas are summarized. Included are embryonal rhabdomyosarcoma, pleomorphic rhabdomyosarcoma, angiosarcoma, alveolar soft part sarcoma, malignant perivascular epithelioid cell tumors (PEComas), osteosarcoma, chondrosarcoma, liposarcomatous tumors, malignant extrarenal rhabdoid tumors, Ewing sarcoma/primitive neuroectodermal tumor, and other rare histotypes. Embryonal rhabdomyosarcoma (20%), Ewing sarcoma/primitive neuroectodermal tumor (17%), angiosarcoma (14%), and pleomorphic rhabdomyosarcoma (13%) appeared to be more common than the others, although there was no single overwhelmingly prevalent histotype in the group. A subset, including embryonal rhabdomyosarcoma, alveolar soft part sarcoma, and PEComas, peak in the premenopausal years, but most of the others were observed in postmenopausal women. Favorable outcomes have been reported for the patients diagnosed with alveolar soft part sarcoma, and the prognosis for their counterparts with PEComa remains a matter of debate. Multimodal therapeutic approaches to contemporary patients with embryonal rhabdomyosarcomas have resulted in significantly improved outcomes. Unfortunately, most of the other sarcomas have been associated with rapid tumor progression and unfavorable patient outcomes. The differential diagnosis for these sarcomas is often extensive and varies by histotype, but their accurate diagnosis fundamentally requires the careful exclusion of biphasic malignancies.

Abstract
Alveolar soft part sarcoma (ASPS) is a very rare, but distinctive type of soft tissue sarcoma, whose name is derived from the pseudoalveolar appearance of its histology. In this report, the FDG PET/CT findings of ASPS are described in a 17-year-old asthmatic female who presented with worsening respiratory symptoms and a pelvic mass. The staging PET showed heterogeneous intense incorporation of FDG within the mass and variable FDG incorporation within the multiple lung nodules. In concordance with other soft tissue sarcomas, PET/CT helped to confirm the anatomic origin of the ASPS, to direct its biopsy, and to assess the distribution of disease.

Abstract
Alveolar soft-part sarcoma (ASPS) is a rare malignant neoplasm with uncertain histogenesis and with a distinctive morphology. It has been described in the oral cavity, but this is the first report of ASPS metastasizing to the maxillary tuber region. A 27-year-old male patient, who was under chemotherapy treatment for ASPS of the thigh, presented in our dental clinic with a painless and pedunculated nodule on the right tuber maxillae. The nodule was erythematous with smooth and lobular surface, measuring 3 cm in maximum diameter. An incisional biopsy was performed and the diagnosis of metastatic ASPS was made. Histologically, the tumor was characterized by a proliferation of polyhedral cells in pseudoalveolar pattern. Tumor cells were large, showing granular cytoplasm, periodic acid-Schiff positive diastase-resistant intracytoplasmic material, and vesicular nuclei with prominent nucleoli. Unfortunately, the patient died 2 months after the diagnosis of the oral metastasis. Metastases of ASPS to the mouth are very rare and indicate a poor prognosis.

Abstract
Alveolar soft part sarcoma (ASPS) is a rare malignant soft tissue tumor, which rarely occurs in bone. We present a case of ASPS in a 23-year-old man with a 2-month history of back pain. Computed tomography scanning and magnetic resonance images demonstrated a destructive process in the 12th thoracic vertebra associated with a unilateral soft tissue mass. The tumor showed evidence of hypervascularity on MRI; it obviously was enhanced on T1-weighted images after injection of Gd-GDPA, and signal voids were shown on all pulse sequences which may help to differentiate ASPS from other tumors of the vertebra. We believe that this is the first case of ASPS arising in a vertebra.

Abstract
Alveolar soft part sarcoma (ASPS) is a distinct, rare soft tissue tumor with an unknown histogenesis and a tendency for late widespread metastases to lung, bone, and brain. It is now clear that they are caused by a specific unbalanced translocation, der(17)t(X;17)(p11;q25), which results in the formation of an ASPSCR1-TFE3 (alias ASPL-TFE3) fusion gene. The rearrangement results in the expression of chimeric transcripts, which can be identified by means of reverse transcriptase-polymerase chain reaction (RT-PCR). We investigated the histogenesis of ASPS and attempted to detect circulating ASPS tumor cells in peripheral blood. The immunohistochemical and genetic details of four cases and one cell line of ASPS were examined. An immunohistochemical analysis and RT-PCR did not detect myogenic differentiation gene MYOD1. The sensitivity of nested RT-PCR for detection of circulating ASPS cells was assessed by demonstrating that the tumor cell-associated gene translocation could be detected in 50 tumor cells/2 mL of blood. Clinically, it was detectable in a peripheral blood sample (2 mL) of ASPS patient with distant metastases. The findings suggest that ASPS is not of skeletal muscle origin. ASPS tumor cells in the peripheral blood could be monitored by RT-PCR.

Abstract
Alveolar soft-part sarcoma (ASPS) is a rare neoplasm with chromosomal translocation that results in ASPL-TFE3 fusion. It is a slow-growing lesion associated with a high incidence of pulmonary and brain metastases indicating poor survival. We demonstrated that the ASPS metastases include also stromal myofibroblasts. These cells proliferate, express smooth-muscle genes, and synthesize extracellular matrix proteins, all of which are characteristics of activated myofibroblasts. The tumor cells also exhibited stromal components such as transforming growth factor beta (TGFbeta)-dependent, hypoxia-regulated cytoglobin (stellate cell activation association protein, cytg/STAP) and prolyl 4-hydroxylase, a collagen cross-linking enzyme. The pulmonary ASPS myofibroblasts synthesize serum response factor (SRF), a repressor of Smad3-mediated TGFbeta signaling essential for myofibroblast differentiation and Smad3. The phosphorylated active Smad3 was found mostly in the tumor cells. The brain tumor cells express cytg/STAP, but in contrast to the lung metastases, they also express SRF, Smad3, and phospho-Smad3. Halofuginone, an inhibitor of myofibroblasts' activation and Smad3 phosphorylation, inhibited tumor development in xenografts derived from renal carcinoma cells harboring a reciprocal ASPL-TFE3 fusion transcript. This inhibition was associated with the inhibition of TGFbeta/SRF signaling, with the inhibition of myofibroblasts' activation, and with the complete loss in TFE3 synthesis by the tumor cells. These results suggest that the myofibroblasts may serve as a novel target for treatment of ASPS metastases.
