Jing Chen, Craig A Mullen
BACKGROUND: Pediatric cancer is rare and its symptoms are often ambiguous. The aims of this study were to investigate the time needed to make a diagnosis, assess the frequency of misdiagnosis, and to determine whether these factors affected survival. METHODS: A review of records of 364 pediatric patients diagnosed with cancer at the University of Rochester Golisano Children's Hospital between 2004 and 2012 was conducted. Data were extracted on patient and health care system-related factors and clinical outcomes...

BACKGROUND: Epithelioid sarcoma is a rare, high-grade malignant tumor of the soft tissue. The incidence of local recurrence, regional lymph node involvement, and distant metastases is high. Epithelioid sarcoma is most often seen in adolescents and young adults. In the early stage before the development of full clinical features, epithelioid sarcoma is often misdiagnosed as a benign disease such as granuloma. CASE PRESENTATION: We report a case of a 74-year-old Japanese woman whose epithelioid sarcoma was initially misdiagnosed as fungal infection...

Extragnathic xanthomas are seen in the bones or as soft tissue masses. They are often associated with hyperlipidemia and are considered as reactive or metabolic lesions. Only 19 cases of xanthomas of the jaws have been reported so far in the English literature. A total of ten cases of central xanthoma of the jaw bones were identified from the Oral and Maxillofacial Pathology biopsy services of the University of Washington and the Tufts University School of Dental Medicine, between the years 2000-2016. The demographic and clinical information on these cases was tabulated logically on the basis of age, gender, location and presence or absence of symptoms, extragnathic lesions and serum hyperlipidemia...

BACKGROUND: Several maternal and birth characteristics have been reported to be associated with an increased risk of many childhood cancers. Our goal was to evaluate the risk of childhood embryonal solid tumors in relation to pre- and perinatal characteristics. METHODS: A case-cohort study was performed using two population-based datasets, which were linked through R software. Tumors were classified as central nervous system (CNS) or non-CNS-embryonal (retinoblastoma, neuroblastoma, renal tumors, germ cell tumors, hepatoblastoma and soft tissue sarcoma)...

Extramedullary relapse (EMR) represents a poor prognostic marker in the course of multiple myeloma (MM). We reviewed data from 329 patients, diagnosed between 2000 and 2010, without extramedullary disease at onset to explore possible risk factors for EMR. The median overall survival of our study cohort was 6.4 years. The risk of EMR was 28 % with a median time from diagnosis to first EMR of 2.2 years (0.2-9.1 years). Patients with soft tissue masses located in extra-osseous organs (EMR-S) showed the worst outcome, compared to those with tumor masses arising from adjacent bone (EMR-B) (median OS 1...

BACKGROUND: Langerhans cell histiocytosis (LCH), typically found in children, is a rare single or multisystem disorder with a wide range of clinical and radiological manifestations. Unusual presentations of LCH are occasionally encountered and it may be difficult to distinguish LCH from an infection or a benign or malignant tumor. RESULTS: A 35-year-old female presented with pain in her back and left buttock, malaise, and weight loss, with a duration of several months...

A 40-year-old woman was referred to our hospital with right lower back pain as the chief complaint. Contrast-enhanced computed tomography (CT) showed a partially-solid tumor within a cyst measuring approximately 6 cm in diameter in the right renal hilum. The solid part was enhanced in the early phase and contrast medium was washed out earlier in the solid part than in the parenchyma in the equilibrium phase. Plain CT revealed partial cyst wall calcification. A soft tissue shadow approximately 10 mm in diameter in the dorsal inferior vena cava at the upper pole of the kidney and a solid tumor adjacent to the iliopsoas muscle and the kidney were detected...

We report a case of thoracic sarcoidosis in a 72-year-old female, snuff taker, who presented with multinodular pulmonary lesions on chest x-ray. Clinical and biological findings were poor. Thoracic imaging showed soft tissue density nodules with irregular borders. The diagnosis of 'cannon ball' metastases was suspected. A thorough investigation strategy could not prove malignancy. A complete radiologic clearing was obtained spontaneously within three months. A rereading of pathology slides performed afterwards showed multinucleated giant cells on hemorrhagic background with a lymphocytic alveolitis...

The giant cell tumor of the tendon sheath (GCTTS) is a benign lesion which arises from the synovium of a joint, bursa or tendon sheath, with 85% of the tumors occurring in the fingers and 12% of the tumors located in large joints such as the knee and ankle. The GCTTS is usually monoarticular, slowly proliferative and rarely locally aggressive. This paper reports three cases of this rare lesion in the knee. Patients presented with painful swelling in the anterior knee, MRI showed localized soft tissue masses which were able to be excised...

BACKGROUND: Rhabdomyosarcoma (RMS) is a malignant tumor of mesenchymal origin and comprises the largest category of soft-tissue sarcomas both in children and adolescents. From a pediatric oncology point of view, RMS has traditionally been classified into alveolar (ARMS) and embryonal (ERMS) subtypes. The anatomical localization of the tumor may vary, but commonly involve the head/neck regions, male and female urogenital tract or the trunk and extremities. CASE PRESENTATION: Here, we report two challenging cases involving 17- and 9-years-olds males where diffuse and multiplex bone lesions suggested either a hematological disease or a primary bone tumor (mesenchymal chondrosarcoma)...

Primary pulmonary synovial sarcoma (PPSS) is a rare disease. Diagnosis is made postoperatively following resection of the tumor. We describe the case of a 39-year-old non-smoking woman whose chest imaging revealed a heterogeneous mass (5.4 cm × 4.6 cm), with soft tissue density in the right upper lobe and pleural effusion in the right hemithorax. The tumor was enhanced on a computed tomography scan, in which enlargement of the mediastinal lymph nodes compressing the adjacent superior vena cava was observed...

Metastasis of lung cancer to soft tissue is rare and patient outcomes are generally poor. There are no reports describing soft tissue metastasis in lung squamous cell carcinoma (SCC), in which gefitinib treatment was effective not only for the primary tumor but also the metastatic lesion. A 61-year-old Asian woman presented to our facility with pain and a mass in the brachium. An additional tumor was identified in the lung. As we suspected soft tissue metastasis of lung cancer, an incisional biopsy was performed, yielding a diagnosis of SCC...

We report a 38-year-old woman with a left lung tumor presenting as obstructive pneumonia. Bronchoscopic examination revealed a polypoid tumor filling the left main bronchus. The tumor was partially resected by a snaring procedure for diagnostic purposes. Microscopic examination revealed a submucosal tumor located underneath normal bronchial epithelium. The tumor was composed of sheets of uniform oval to cuboidal cells encompassing numerous blood vessels. Immunohistochemically, the tumor cells exhibited smooth muscle markers, but were negative for neuroendocrine markers...

Granular cell tumors (GCTs) are soft tissue neoplasms that originate from Schwann cells. They occur predominantly in the oral cavity, skin, and breast tissues. Gastrointestinal GCTs are very rare, accounting for only eight percent of all GCTs, most of which are located in the esophagus. Endoscopic ultrasound has been a breakthrough in diagnosing GCTs because it provides precise information on the depth of tumor invasion, thus narrowing the differential diagnosis of subepithelial lesions in the esophagus. However, the definitive diagnosis requires histological confirmation of the lesion...

Since its foundation by remarkably talented and insightful individuals, prominently including Pepper Dehner, pediatric soft tissue tumor pathology has developed at an immense rate. The morphologic classification of tumoral entities has extensively been corroborated, but has also evolved with refinement or realignment of these classifications, through accruing molecular data, with many derivative ancillary diagnostic assays now already well-established. Tumors of unclear histogenesis, classically morphologically undifferentiated, are prominent amongst pediatric sarcomas, however, the classes of undifferentiated round- or spindle-cell-tumors-not-otherwise-specified are being dismantled gradually with the identification of their molecular underpinnings...

Soft tissue myoepithelial neoplasms are a rare yet diverse group of tumors, ranging from benign to malignant lesions. Their presentation in the head and neck region is uncommon and represents a challenging diagnosis. Early identification of myoepithelial carcinoma is crucial given its more aggressive course compared to its benign counterpart, although the histopathological distinction between the two can be difficult. EWSR1 gene rearrangement is found in half the cases and has a speculative role in pathogenesis...

Thyroid tumors affect all age groups, including children and adolescents. Malignant cancer of the thyroid is a relatively uncommon disease in pediatric age. In the recent decades the incidence of paediatric differentiated thyroid carcinoma (DTC) has increased. DTC in paediatric age is rare and has an excellent prognosis. Compared to adult counterpart, DTC in childhood presents some different features as follows: larger volume at the diagnosis, more frequent multicentricity (both mono- and bilateral), earlier local involvement of soft tissue of the neck, earlier lymph node involvement, distant metastases 3-4 times more frequent (most often in the lungs and almost always functional) and more common post-operatory recurrence; nevertheless, the prognosis of DTC in childhood is better and the survival greater than in adult...

BACKGROUND: Soft tissue sarcomas (STS) are a heterogenous group of rare tumors that involve the connective tissue in the body (e.g. muscle, tendons). As with many rare tumors, little is known about the impact of STS on patient well-being. OBJECTIVE: The aim of this review was to better understand current knowledge related to patient experience and quality of life (QOL) following diagnosis of STS. METHODS: A systematic review of English-language articles published from 2005 to 2015 was conducted in the PubMed/MEDLINE, Embase, PsychINFO, and Evidence-Based Medicine databases...
