INTRODUCTION: Intramuscular hemangioma (IMH) is a rare congenital soft tissue tumor. Here, we report a case of IMH patient who had undergone several surgeries and other treatments that were all ineffective before he visited us. CLINICAL FINDINGS: This IMH patient was a 16-yearold male who was born with a tumor of unknown size in his right hand and forearm. On physical examination, the tumor and skin flap complex was seen with a size of 14 cm_12 cm in his right hand, and the multiple postoperative scars were shown on his right hand and forearm...

BACKGROUND: Prostate cancer involving the rectal wall is rare and may lead to diagnostic pitfalls. CASE PRESENTATION: Out of 9504 patients with rectal tumors between January 2003 and January 2015, 9 patients (elderly with a mean age of 74 years) with prostate cancer involving the rectal wall were clinically misdiagnosed with rectal cancer. The lesions were located in the rectum, and included 3 circumferential rectal masses, 1 ulceration lesion, 1 crater-like mass, and 4 protruding lesions...

Background Hemangiomas are sometimes difficult to diagnose with current techniques. Sluggish speed signs (SSS) are a phenomenon that: (i) cannot be depicted as Doppler flow on Doppler ultrasound; (ii) can be observed as fluid movements on Doppler ultrasound; and (iii) cannot be depicted as waveforms on pulse Doppler mode. We hypothesized that SSS could be diagnostic indicators for hemangiomas. Purpose To evaluate whether ultrasound findings, in particular those relating to SSS, are a reliable tool for detecting hemangiomas compared to magnetic resonance imaging (MRI) and the gold standard for hemangioma diagnosis: pathological examination by biopsy or after surgical resection...

PURPOSE: The advent of microvascular free tissue transfer has provided the reconstructive surgeon with an enormous array of treatment options for reconstruction of large head and neck defects. However, when indicated by defect size, the need for more than 1 flap not only increases surgical complexity but also patient morbidity. The combination of the anterolateral thigh (ALT) flap and the tensor fascia latae (TFL) flap can be used to reconstruct such complex head and neck defects, thereby minimizing any additional morbidity that would be imposed by an additional flap harvest site...

Proton Magnetic Resonance Spectroscopic Imaging ((1)H MRSI) has shown great potential in tumor diagnosis since it provides localized biochemical information discriminating different tissue types, though it typically has low spatial resolution. Magnetic Resonance Imaging (MRI) is widely used in tumor diagnosis as an in vivo tool due to its high resolution and excellent soft tissue discrimination. This paper presents an advanced data fusion scheme for brain tumor diagnosis using both MRSI and MRI data to improve the tumor differentiation accuracy of MRSI alone...

PURPOSE: Spermatic cord sarcoma is a rare disease, which management remains controversial due to the lack of guidelines. The standard therapeutic approach is surgical: wide soft-tissue resection with radical inguinal orchidectomy, The diagnosis is made during the analysis of the specimen. The high rate of local recurrence indicates adjuvant radiotherapy of the tumor bed. The aim of this series is to determine the efficacy and safety of postoperative intensity-modulated radiotherapy for spermatic cord sarcomas...

BACKGROUND: Transitional cell carcinoma (TCC) originating from the renal pelvis with a venous tumor thrombus is a rare entity. However, clinicians should be aware of it because of its high malignancy and poor prognosis. CASE PRESENTATION: Here, we report three cases of pathologically confirmed TCC originating from the renal pelvis with extension into the renal vein or inferior vena cava (IVC). Of these patients, two are males and one is female (58~73 years old)...

BACKGROUND: Dermoid tumors are slow growing, benign CNS lesions. CASE DESCRIPTION: This case study concerns a 29-year-old female with a 6-year history of lower extremity paresthesias attributed to magnetic resonance (MR)/computed tomography (CT) documented intradural dermoid tumor that extended from L1 to S1. On MR, it was hypointense on T1, hyperintense on T2, and did not enhance with gadolinium. CT showed hyperdensity at the L1-L2 levels. The craniocervical MR imaging showed small hyperintense foci in the cisternal space favoring "fat dissemination...

PURPOSE: Kaposiform hemangioendothelioma (KHE) is a rare, aggressive vascular tumor that typically occurs during infancy or early childhood. Though several case reports have discussed the imaging findings of KHE, larger comprehensive studies are lacking. The purpose of this study was to evaluate the imaging findings of KHE in children. MATERIALS AND METHODS: A total of twelve cases of pathologically proven KHE were collected by searching our institution's pathology database for children diagnosed between January 2004 and April 2016 (6 male, 6 female; median age: 3 months; age range 7days - 18 years)...

Infantile soft tissue tumors of the head are very rare and the majority of them are myofibromas. The authors present the case of a 1-day-old boy with a scalp tumor with several distinct histopathological features including myofibroma, hemangiopericytoma, and fibrosarcoma consistent with the diagnosis of composite infantile myofibromatosis. Genetic testing was negative for trisomy 17, translocation (12; 15), FUS, and ETV6 translocations. Despite the ominous histopathological features, the clinical course was benign...

Hand liposarcomas are not well recognized in common practice, which leads to erroneous diagnostics and delayed proper treatment. We reported a case of a myxoid liposarcoma classified as stage IIb, and developed in the palmar side of the left hand in a 38-year-old man. There was an initial tumor reduction by a sclerosing agent injection that proved to be a failure. An open excisional biopsy confirmed the diagnostic after pathology examination. Recurrence occurred after 2 years, followed by a second resection and an adjunctive radiotherapy...

Radiation therapy is a treatment modality that is often used in the uro-oncological setting. The common indication for the radiation therapy in the urological sphere is prostate cancer, whether it is used primarily as a radical approach, or postoperatively as adjuvant or salvage therapy. All urological organs are sensitive to radiation injury with the urinary bladder being the most susceptible with a typical cascade including acute and late changes, arising in the dose-dependent manner. The common indication for radiation therapy in urology is prostate cancer, which collaterally affects the urinary bladder and rarely urethra (especially the bulbo-membranous urethra)...

Superficial acral fibromyxoma (SAFM) is a rare soft tissue tumor that frequently involves the periungual and subungual regions of acral surfaces. Macroscopically, it appears as a flesh-colored dome-shaped solitary mass; microscopically, it consists of a moderately cellular proliferation of spindle-shaped fibroblast-like cells embedded in a myxocollagenous stroma and arranged in a loose storiform and focally fascicular pattern. The tumor cells are immunoreactive for CD34, epithelial membrane antigen, CD99, and CD10...

Osteoid osteoma and osteoblastoma are rare benign bone-forming tumors with very similar histological features. They are nowadays considered as two distinct entities. Progression of an osteoid osteoma to osteoblastoma is considered very rare with only a few cases reported in the literature. Herein we describe a case of an osteoid osteoma of the thoracic spine in a 29-year-old woman that was initially treated conservatively and progressed to osteoblastoma 5 years following the initial diagnosis. Imaging revealed an increase in the size of the spinal lesion that was surrounded by extensive paraspinal abnormal soft tissue that raised suspicion for sarcomatous transformation...

A 52-year-old man underwent Ga DOTATOC PET/CT scan for postsurgical staging of a neuroendocrine tumor of the lung. The PET images showed a single focus of increased activity in a soft tissue nodule located posteriorly to a cervical vertebra. Surgical removal of the lesion led to the histological diagnosis of retiform hemangioendothelioma.

BACKGROUND: Solitary fibrous tumors (SFT) arising from the larynx are extremely rare; most occur in the supraglottic larynx. CASE REPORT: Herein, we detail a new case of a subglottic SFT presenting as a well-encapsulated soft-tissue tumor with hoarseness. It showed isoattenuation, similar to the adjacent muscle on pre-contrast computed tomography (CT) images, and strong, heterogeneous enhancement following contrast material administration, which may reflect hypervascularity...

BACKGROUND: Angiolipomas are benign tumors usually seen in patients during their 2(nd) and 3(rd) decades. The subcutaneous region of the trunk, neck and extremities are the places where they generally settle. There is only one case report on angiolipoma in the knee joint that was resected by arthroscopic procedure in the English literature. CASE REPORT: We present a case of a giant-size multilobular non-infiltrating angiolipoma, extending outside of the right knee joint and causing lateral patellar dislocation in a thirteen-year-old boy...

BACKGROUND Venous thromboembolism (VTE), comprising deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common, serious cardiovascular event. Predisposing factors include genetic disorders, immobility, and underlying malignancy. Soft tissue tumors are by contrast rare, but should be included in the differential etiology of DVT, especially when the patient is young and has few thrombotic risk factors. CASE REPORT We present a 40-year-old patient whose initial diagnosis was spontaneous DVT of the lower leg, treated conventionally...
