Lipoma arborescens (LA) is an uncommon non-neoplastic disorder that may affect almost any joint, mainly the knee. LA is very rare in the elbow, and there are only a few cases reported in the literature. This study aimed to describe a case of LA in the elbow, presenting with features of a high-grade tumor. The authors report the case of a 51-years-old male who presented to this institution with pain and swelling on the left elbow. The patient had a seven-year history of investigation, with inconclusive diagnosis...

Evaluation of a hand mass and subsequent surgical treatment is a frequent clinical encounter for the practicing hand surgeon. The clinical evaluation of benign and malignant hand tumors has traditionally focused on diagnosis, surgical excision, and reconstruction. There is a paucity of literature discussing the determining factors for a hand mass biopsy, its appropriate technique, and postbiopsy preparation and handling. This review discusses the approaches of the hand surgeon and orthopedic oncologist to a soft tissue mass in the hand and clarifies the term biopsy...

BACKGROUND: Multi-institutional collaborations provide granularity lacking in epidemiologic datasets to enable in-depth study of rare diseases. For pts with superficial, high-grade soft tissue sarcomas (STS) of the trunk/extremity, the value of radiation therapy (RT) is not clear. We aimed to utilize the 7-institution US-Sarcoma-Collaborative (USSC) and the National Cancer Database (NCDB) to investigate this issue. STUDY DESIGN: All adult pts with superficial truncal/extremity high-grade STS who underwent primary curative-intent resection from 2000-2016 at USSC institutions or were included in the NCDB from 2004-2013 were analyzed...

Myopericytoma is a soft-tissue tumor of perivascular cells (pericytes). It is slow-growing, usually asymptomatic, and generally benign, although a malignant variant has been described. The etiology is unknown, but it has been associated with local trauma. The most common location is on the distal extremities. Histologically, it is characterized by a well-circumscribed, non-encapsulated proliferation of spindle shaped cells similar to myofibroblasts with oval nuclei and eosinophilic cytoplasm, arranged in perivascular concentric rings...

A vascular leiomyoma is a vascular soft tissue tumor that is relatively rare and benign. They usually occur as solitary lesions and are well encapsulated. The present study describes a unique case of vascular leiomyoma causing erosions of a metatarsal secondary to compression from the tumor. We present a female in her fourth decade of life with osseous malformations of the third metatarsal that became painful after an acute trauma to the foot.

Rhabdomyosarcoma is a malignant soft tissue tumor which shows skeletal muscle differentiation. Leptomeningeal metastasis can occur as a late complication, but currently there are no reports that have documented the cytologic features in cerebrospinal fluid (CSF). We report a case of metastatic alveolar rhabdomyosarcoma diagnosed in the CSF of a 28-year-old male who was originally diagnosed with rhabdomyosarcoma on the neck, and that went through systemic therapy. The tumor was positive for anaplastic lymphoma kinase, but progressed despite additional therapy with crizotinib...

RATIONALE: Liposarcoma (LPS) is a relatively rare malignant soft tissue tumor. Management of LPS including diagnosis is difficult, because it has no characteristic symptoms and no established effective treatment. Herein we reported an extremely rare case of intussusception induced by primary small bowel LPS. PATIENT'S CONCERN: A-84-year-old male was a consult to our Emergency Department with symptoms of a terrible general fatigue, abdominal pain, and vomiting. DIAGNOSIS: Abdominal ultrasonography and computed tomography (CT) revealed probable intussusception...

Soft tissue sarcomas (STS) have minimal expression of PD-L1, a biomarker for PD-1 therapy efficacy. Radiotherapy (RT) has been shown to increase PD-L1 expression pre-clinically. We examined the expression of PD-L1, pre- and post-RT, in 46 Stage II-III STS patients treated with pre-operative RT (50-50.4 Gy in 25-28 fractions) followed by resection. Five additional patients who did not receive RT were utilized as controls. PD-L1 expression on biopsy and resection samples was evaluated by immunochemistry using the anti PD-L1 monoclonal antibody (E1L3 N clone; Cell Signaling)...

Alveolar rhabdomyosarcoma (aRMS) is an aggressive subtype of the most common soft tissue cancer in children. A hallmark of aRMS tumors is incomplete myogenic differentiation despite expression of master myogenic regulators such as MyoD. We previously reported that histone methyltransferase KMT1A suppresses MyoD function to maintain an undifferentiated state in aRMS cells, and that loss of KMT1A is sufficient to induce differentiation and suppress malignant phenotypes in these cells. Here, we develop a chemical compound screening approach using MyoD-responsive luciferase reporter myoblast cells to identify compounds that alleviate suppression of MyoD-mediated differentiation by KMT1A...

Predicting outcomes in patients with soft tissue sarcoma (STS) is challenging. To improve these predictions, we retrospectively analyzed common nutritional assessment systems, including Glasgow prognostic score (GPS), Geriatric Nutritional Risk Index (GNRI), neutrophil⁻lymphocyte ratio (NLR), platelet⁻lymphocyte ratio (PLR), and controlling nutritional (CONUT) score against outcomes in 103 patients with STS, of whom 15 (14.6%) died within 1 year of diagnosis. GPS, GNRI, NLR, PLR, and CONUT scores significantly differed between patients who died within one year and patients who lived longer...

BACKGROUND: Rhabdomyosarcomas (RMSs) are the most frequent soft tissue sarcoma in children and adolescents, defined by skeletal muscle differentiation and the status of FOXO1 fusions. In pediatric malignancies, in particular RMS, scant and controversial observations are reported about PD-L1 expression as a putative biomarker and few immune checkpoint clinical trials are conducted. METHODS: PD-L1 assessment was evaluated by immunohistochemistry (IHC) utilizing two anti-PDL1 antibodies, in a pilot cohort of 25 RMS...

Meningiomas generally present as slow-growing, expanding intracranial lesions and are the most common benign intracranial tumor in adults. Rarely, meningiomas can exhibit malignant potential and present as extracranial soft-tissue masses through extension or as primary extracranial cutaneous neoplasms. Although they are uncommonly encountered by dermatologists, it is important to include meningioma in the differential diagnosis for scalp neoplasms. We present a rare case of a 68-year-old woman with scalp metastasis of meningioma 11 years after initial resection of the primary tumor...

Synovial sarcoma (SS) is a malignant mesenchymal tumor with variable epithelial differentiation that affects mostly young adults and can arise at any anatomic site. Primary intrathoracic SS is very rare accounting for <0.5% of all lung tumors. Most commonly, it arises from the lung followed by pleura and mediastinum. Primary pulmonary SS (PPSS) affects both sexes equally with no preference for any hemithorax. The morphology, immunostaining properties, cytogenetic features, and management strategy of PPSS are similar to that of soft tissue SS...
