Neoadjuvant radiation therapy, followed by definitive surgical resection, remains the standard of care for resectable high-grade and unresectable soft tissue sarcomas. Proton therapy offers the promise of highly conformal dose distributions with improved sparing of neighboring normal tissues as compared with conformal and intensity modulated photon techniques. It is unclear whether proton therapy may offer an improved tumoral response, especially with dose escalation, in this relatively radio-insensitive tumor type...

Lower-extremities sarcoma patients, with bone tumor and soft-tissue sarcoma, are a unique population at high risk of physical dysfunction and chronic heart diseases. Thus, providing an adequate physical activity (PA) program constitutes a primary part of the adjuvant treatment, aiming to improve patients' quality of life. The main goal of this paper is to offer clear suggestions for clinicians regarding PA around the time between diagnosis and offered treatments. These preliminary recommendations reflect our interpretation of the clinical and preclinical data published on this topic, after a systematic search on the PubMed database...

Ancient schwannoma is a rare variant of schwannoma associated with a longstanding course. They differ from classical schwannomas in the long duration for this subtype of schwannoma to develop and also by demonstrating haemorrhagic and degenerative changes with nuclear atypia. It is because of these histologic hallmarks that they are frequently misdiagnosed as malignant tumours. They usually involve the major nerves of flexor surfaces in upper extremity such as the ulnar and median nerve but schwannomas of the radial nerve are a rare entity...

Angiosarcoma is a rare soft tissue sarcoma, and the data about its clinicopathological features and prognostic factors are limited. The purpose of the present study was to report a large series of angiosarcoma at a single institution. Clinical data from 200 cases of angiosarcoma from the Shanghai Cancer Center (Shanghai, China) between March 2006 and March 2014 were retrospectively analyzed. The study population included 97 males and 103 females with ages between 4 and 91 years (median, 53 years). According to the tumor location, 200 cases were divided into 4 groups: i) Tumors involving the head and neck; ii) breast; iii) viscera (including internal organs and bone); and iv) soft tissue (including trunk and extremities)...

Synovial sarcoma is a rare occurrence in the lower extremity, although the presenting symptoms can mimic those of other more common and benign musculoskeletal pathologies. We present the case of a patient who was originally thought to have a Morton's neuroma or ganglionic cyst. The correct diagnosis, synovial sarcoma, was determined only after an unplanned excision. Despite the patient presenting with symptoms similar to those of a compressive neuropathy, a high index of suspicion should be present when a patient presents with any soft tissue mass, especially if it has an unusual clinical appearance to avoid an unplanned excision...

Malignant peripheral nerve sheath tumor is a rare tumor occurring in 5%-10% of all malignant soft tissues sarcomas and triton tumor arising from neurofibromatosis type 1 (NF-1) is even rarer with associated high rate of mortality. No case of triton tumor has been reported in Nigeria to the best of our knowledge. We seek to report a case of lately detected retroperitoneal triton tumor presenting in a 12-year-old Nigerian child who was brought with bilateral lower limb weaknesses, weight loss, and a right lumbar mass...

Jaundice in children is more often due to hepatic disease than obstruction. Differential considerations for obstructive jaundice in children include choledocholithiasis, choledochal cysts and rare neoplasms. Rhabdomyosarcoma, the most common soft tissue sarcoma in pediatric patients, typically involves the head and neck, genitourinary system and extremities. Embryonal rhabdomyosarcoma of the biliary tree is a rare entity. We present a 3-year-old boy with abrupt onset obstructive jaundice. Although initial imaging suggested a dilated biliary system with fusiform common bile duct, sludge, and possible cholelithiasis, endoscopic retrograde cholangiopancreatogram (ERCP) diagnosed a common bile duct embryonal rhabdomyosarcoma and further imaging showed involvement of the cystic duct...

REVIEW
Courtney E Sherman, Peter M Murray
Tumor-like conditions of the hand and upper extremity typically present as masses and can be confused as more serious conditions. The differential diagnosis of these lesions can cross over with many more commonly recognized benign and malignant upper limb tumors, and it is, therefore, important for the hand surgeon to be familiar with tumor-like conditions. The diagnosis of these lesions often can be made on clinical grounds supported by a careful physical examination and plain film radiography. Advanced imaging and excisional biopsy may be needed in many circumstances to secure the diagnosis given their similarity with bone and soft tissue sarcomas...

Proximal-type ES (PES) is a rare and aggressive sarcoma originated from soft tissues with uncertain differentiation. It mainly affects middle-aged patients and often locates in proximal extremity and deep-seated tissues. Only one case of PES located in the skull base has been reported to date. Herein, we report two cases of PES occurred in the middle cranial fossa in two middle-aged Chinese women. Microscopically, the tumors were consisted of epithelial-like cells with or without rhabdoid cells. And frequent mitotic activity and coagulation necrosis were present...

BACKGROUND: Soft tissue sarcomas are rare neoplasms that can occur in the thoracic wall, abdominal wall, extremities, and inguinal region. Wide local resection, with precise histological margin control, results in large skin defects that are challenging to close. Various repair procedures, such as vertical rectus abdominis flaps (VRAM), latissimus dorsi flaps, and tensor fascia lata (TFL) flaps are used to cover broad thoracic wall defects. Although the cosmetic reconstruction results of using these flaps are often excellent, each has significant drawbacks...

David R Lucas
Myxoinflammatory fibroblastic sarcoma is a rare soft tissue tumor with most occurring in the distal extremities of adult patients. It has a high rate of local recurrence and a low rate of metastasis. Because it may appear benign on clinical examination, and because the microscopic features are generally underrecognized, it is often inadequately treated and misdiagnosed. In this review, based upon experience and that of the literature, the intent is to highlight salient clinicopathologic features, detail the broad microscopic spectrum including high-grade aggressive variants, review the molecular features, and discuss its relation to hemosiderotic fibrolipomatous tumor...

BACKGROUND: Clear cell sarcoma is a rare malignant soft tissue neoplasm that typically involves tendons and aponeurosis. Clear cell sarcoma occurring in the dermis is an extremely rare occurrence. It is difficult to differentiate between this neoplasm and dermal malignant melanoma because they both have similar morphologic and immunohistochemical features. Although rare, clear cell sarcoma of the skin typically occur in the extremities. To our knowledge, there are no reported cases of primary clear cell sarcoma of the skin occurring in the neck...

Background: Soft-tissue sarcomas (STS) are a group of rare, heterogeneous and aggressive tumors, with high metastatic risk and relatively few efficient systemic therapies. We hypothesized that the Genomic Grade Index (GGI), a 108-gene signature previously developed in early-stage breast cancer, might improve the prognostic assessment of patients with early-stage STS. Patients and methods: We collected gene expression and clinicopathological data of 678 operated STS, and searched for correlations between the GGI-based classification and clinicopathological variables, including the metastasis-free survival (MFS)...

INTRODUCTION: Primary spinal epidural extraskeletal Ewing's sarcoma (EES) is extremely rare, with a peak incidence in the second decade of life. EES in old people is challenging to treat due to the lack of specific guidelines. In this paper, I present a unique case of adult primary cervical epidural EES with a 13-month follow-up. A short literature review of the therapeutic approaches and prognosis is also presented. PRESENTATION OF CASE: I present a case of a 49-year old male patient who presented with right upper limb pain, numbness, hand grip weakness, and hyperreflexia of 3 months duration...

RATIONALE: Myeloid sarcomas (MSs) are rare malignant hematological tumors. They most commonly occur in patients with acute or chronic myeloid leukemia. A de novo MS with no evidence of blood system disease is rare, but may represent the first sign of a systemic illness that precedes a full-blown disease. Herein, we report the computed tomography (CT) findings of an extremely rare case of a nonleukemic MS that progressed to acute myelogenous leukemia (AML) and simultaneously involved the small intestine, kidneys, mesentery, and mesenteric lymph nodes...

BACKGROUND: Despite multimodality limb salvage treatment (LST) for locally advanced extremity soft tissue sarcoma (ESTS), some patients still need an amputation. Indications for amputation and oncological outcome for these patients are described. METHODS: Between 1996 and 2016, all patients who underwent an amputation for ESTS were included. Patients who underwent an amputation as primary or as non-primary treatment formed Group I and II, respectively. RESULTS: Thirty-nine patients were included, 16 in Group I (41%) and 23 in Group II (59%)...

Metastasis of a nonvisceral leiomyosarcoma to the heart is rare. We present the case of a man with a history of an upper extremity cancerous lesion that was completely resected with appropriate surveillance monitoring, which then metastasized to the heart 14 years later, presenting as superior vena cava syndrome. Full evaluation found no other metastatic lesions, including no residual sarcoma at the former primary site. We include transthoracic echocardiography and computed tomography images of unusual presentation of the large mass extending from the caudal superior vena cava to the right atrium and into the right ventricle across the tricuspid valve...
