About one third of patients with rhabdoid tumors (RT) harbor a heterozygous germline variant in SMARCB1. Molecular diagnosis therefore keeps a crucial place in the diagnosis of RT, and genetic counseling should be systematically recommended. However, immunohistochemistry has progressively replaced molecular tools to assess the status of SMARCB1 in tumors; the necessity of analyzing SMARCB1 status in the tumor may thus be less considered by neuropathologists and pediatric neuro-oncologists. In the present manuscript as aforementioned, we report on two patients with bifocal RT in the first month of life and in whom no germline variant was initially found in the SMARCB1 coding sequence...

BACKGROUND: Ultrasound has been used in the diagnosis of soft-tissue lesions for well over a decade. Lipomas are the most common, benign, soft-tissue tumor and comprise adipose tissue. The sensitivity and specificity of diagnosing lipomas on ultrasound vary greatly in the literature. PURPOSE: To perform a systematic review on ultrasonography in soft-tissue lipomas to better ascertain the true diagnostic value of this test. MATERIAL AND METHODS: A systematic review of the diagnostic value of ultrasound in lipomas was performed where possible in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

Schwannoma is a benign tumor that originates from Schwann cells of the peripheral nerve. Occurring as a common tumor in the head and neck region, its intraoral presentation is rare which accounts for only 1%. They are solitary, slow-growing, smooth-surfaced, usually asymptomatic, and encapsulated tumor. This paper comprises two case reports, both of which presented with an intraoral soft tissue swelling which turned out to be schwannoma of buccal mucosa and infratemporal fossa with extension into the oral cavity, respectively...

Magnetic resonance imaging (MRI) is often "one stop shop" for evaluating female pelvic masses that helps in diagnosis, staging, and restaging of these tumors. A pelvic mass can arise from any tissue present within the pelvis. Although most masses in the female pelvis arise from the reproductive organs, masses may also arise from the gastrointestinal tract, urinary system, adjacent soft tissues, peritoneum, etc. It may not always be possible to determine the site of origin or distinguish these masses based on imaging characteristics...

Capillary hemangiomas are common benign vascular tumors on skin and soft tissues, but developing as an intradural and extramedullary (IDEM) tumor in spine is extremely rare. In this report, we present IDEM tumor compressing thoracic cord in T2-3 level with extensive arachnoiditis below the tumor level in a 60-year-old man. The lesion was removed and histological diagnosis was capillary hemangioma. Prompt diagnosis and resection are important to avoid neurological deterioration from acute hemorrhagic condition...

Hemosiderotic fibrohistiocytic lipomatous tumors are rare neoplasms that were first described in 2000. Initially considered a benign lipotamous lesion of the soft tissues, nowadays they are considered to be a locally aggressive tumor. They occur mainly in the foot and ankle of women in their fifth and sixth decades, although they may be found in any place in the lower limbs and, more rarely, in other parts of the body. Histologically, hemosiderotic fibrohistiocytic lipomatous tumors consist of a mixture of mature adipose tissue, fusiform cell fascicles, macrophages that often contain cytoplasmic hemosiderin, mononuclear inflammatory infiltrate, and stroma that may be focally myxoid...

Synovial sarcomas are rare malignant tumors supposed to arise from pluripotent mesenchymal stem cells predominantly affecting the deep soft tissue of the lower and upper extremities in young adults. The occurrence of this tumor entity in the head and neck is very uncommon and hence, timely diagnosis and treatment of synovial sarcoma in this region remain a challenge. We describe the clinical and molecular pathological features of a biphasic synovial sarcoma of the epiglottis, a site where the primary manifestation of this tumor entity has not been documented to date...

INTRODUCTION: Ectopic cervical thymus (ECT) is a rare embryological abnormality in children. It can be revealed by a compressive neck mass mistaken for a malignant tumor. Through a new case of ECT, we review the embryopathogenesis, diagnostic difficulties and therapeutic features. CLINICAL OBSERVATION: A 19-month-old girl presented a right cervical mass that quickly increased in size, causing intermittent dyspnea. The physical examination objectified a 6-cm, soft and compressible, painless right cervical tumefaction, extending from the mastoid area to the ipsilateral supraclavicular fossa...

BACKGROUND: Solitary fibrous tumor is an uncommon soft tissue neoplasm with intermediate biological behavior, which rarely metastasizes. Malignant solitary fibrous tumor, although not clearly defined, is rarely described in the prostate. The present case is characterized by some peculiarities if compared with previously reported cases of prostatic malignant solitary fibrous tumor. Firstly, it does not show a homogeneous morphology: part of the neoplasm (about 50%) showed the features of a conventional solitary fibrous tumor, while the remaining part showed the features of a malignant solitary fibrous tumor...

Myoepithelial neoplasms of soft tissue represent a heterogeneous group of lesions, encompassing both benign entities as myoepithelioma (ME) and highly aggressive tumors as myoepithelial carcinoma (MEC). We describe a case of pediatric soft tissue MEC with peculiar features that may lead to misdiagnosis: congenital onset and presence of a benign component with predominant cystic structure. Few cases of congenital MEC have been reported, but the coexistence of MEC with ME is even more rare, accounting for less than 1% of myoepithelial tumors...

Marco Bo Hansen
Necrotising soft tissue infection (NSTI) is a life-threatening and rapidly progressing bacterial infection involving one or more layers of the soft tissue compartments causing necrosis. The amputation and mortality rates remain high despite increased focus on the patients. Timely treatment, including surgical intervention, reduces the risk of severe disability and death. However, the lack of pathognomonic signs impedes early diagnosis and treatment. Moreover, the rarity of the disease makes it difficult to conduct large prospective studies, thus prospective research is almost non-existent in this group of patients...

REVIEW
J M Lieb, F J Ahlhelm
METHODICAL ISSUE: The anatomy of the sellar region is complex and tumors of the sellar region are very variable because they arise from the many different tissue types in the sellar region, ranging from benign to life-threatening. Despite this variety, approximately 80% of sellar region tumors are due to the 5 most common lesions: adenomas, meningiomas, aneurysms, astrocytomas and craniopharyngiomas. STANDARD RADIOLOGICAL METHODS: In addition to clinical and laboratory results, the magnetic resonance imaging (MRI) and computed tomography (CT) results including the exact anatomical position and the proliferation pattern of the lesion are decisive for the diagnosis...

BACKGROUND: Evofosfamide is a hypoxia-activated prodrug of bromo-isophosphoramide mustard. We aimed to assess the benefit of adding evofosfamide to doxorubicin as first-line therapy for advanced soft-tissue sarcomas. METHODS: We did this international, open-label, randomised, phase 3, multicentre trial (TH CR-406/SARC021) at 81 academic or community investigational sites in 13 countries. Eligible patients were aged 15 years or older with a diagnosis of an advanced unresectable or metastatic soft-tissue sarcoma, of intermediate or high grade, for which no standard curative therapy was available, an Eastern Cooperative Oncology Group performance status of 0-1, and measurable disease by Response Evaluation Criteria in Solid Tumors version 1...

A glomus tumor is an uncommon, predominantly benign, neoplastic lesion that primarily involves a thermoregulatory microvascular apparatus, the glomus body. Although these lesions can occur anywhere in the body, the subungual tissue of the hand represents the most common presentation site. Glomus tumors are not often encountered in the foot. Symptoms traditionally include the classic triad of pain, pressure, and cold sensitivity. This case report describes a variant location for a glomus tumor in the subcuticular tissue adjacent to the medial middle phalanx of the second toe...
