Head and neck rhabdomyosarcoma occurs frequently in children and adolescents, and has been well studied in that population. In contrast, it is rare in adults and is not as well characterized clinically and pathologically. Seven cases of adult rhabdomyosarcoma occurring in head and neck were retrieved from the archives of Department of Pathology and Division of Oral Pathology at University of Washington. Radiologic findings and clinical history, as well as pathologic findings from hematoxylin and eosin slides and immunohistochemistry for myogenic markers were reviewed...

PURPOSE: While pancreaticoduodenectomy (PD) has been extensively studied in adults, there are few data pertaining specifically to pediatric patients. We retrospectively analyzed PD-associated morbidity and mortality in pediatric patients. METHODS: Our analytic cohort included all consecutive patients ≤18years of age treated at our institution from 1993 to 2015 who underwent PD. Patient data (demographics, disease characteristics, surgical and adjuvant treatment, length of hospital stay, and postoperative course) were extracted from the medical records...

Soft tissue sarcoma constitutes 8% of all tumors in adolescent and young adults (AYA), with rhabdomyosarcoma (RMS) accounting for 5.2% to 6.5% of the soft tissue sarcoma total within this group. AYAs have a higher propensity for metastasis and inferior outcomes. Metastases to the breast have been reported in ∼3% to 6% of RMS cases. A review of our hospital's tumor registry identified cases of RMS diagnosed between January 1, 2004 and December 31, 2013. A total of 46 patients with RMS were identified, having a mean age of 12...

The histologic differential diagnosis of pediatric and adult round cell tumors is vast and includes the recently recognized entity CIC-DUX4 fusion-positive round cell tumor. The diagnosis of CIC-DUX4 tumor can be suggested by light microscopic and immunohistochemical features, but currently, definitive diagnosis requires ancillary genetic testing such as conventional karyotyping, fluorescence in situ hybridization, or molecular methods. We sought to determine whether DUX4 expression would serve as a fusion-specific immunohistochemical marker distinguishing CIC-DUX4 tumor from potential histologic mimics...

AIM: A nomogram for prediction of 12-year sarcoma-specific survival has been developed based on patients with soft tissue sarcomas treated in Memorial Sloan Kettering Cancer Centre (MSKCC). We aim to evaluate the predictive accuracy of the MSKCC sarcoma nomogram in a cohort of patients treated at an Asian institution. This has not been validated in an Asian population and thus its universal applicability remains unproven. MATERIALS AND METHODS: Between 1990 and 2013, 840 adult patients underwent treatment for primary soft tissue sarcoma (STS) at the National Cancer Centre Singapore...

: Rhabdomyosarcoma (RMS) is a rare mesenchymal tumor. The aim of the present study was to develop a patient-derived orthotopic xenograft (PDOX) mouse model of RMS and compare the PDOX model to a subcutaneous (s.c.) transplant model. A patient RMS from a striated muscle was grown orthotopically in the right biceps femoris muscle and right quadriceps muscle of nude mice to establish a PDOX model, as well as under the skin to establish a s.c. MODEL: PDOX tumors grew at statistically-significant faster rate compared to the s...

BACKGROUND: Vertebral compression fractures are a common result of osteoporosis and osteopenia secondary to steroid use and chemotherapy treatment. Balloon kyphoplasty is a treatment option with good to excellent results well described in adults. Although a few recent studies have been published regarding the use of kyphoplasty in children, no formal indication exists for the pediatric population. The purpose of this study is to describe the outcomes of 3 chronically ill children with intractable pain from vertebral compression fractures, managed with kyphoplasty...

We present a rare case of retroperitoneal dedifferentiated liposarcoma (DDLPS) masquerading as rhabdomyosarcoma. The patient was a 74-year-old man, complaining a loss of appetite. Abdominal computed tomography revealed a retroperitoneal mass, 10 cm in diameter, between the liver and the right adrenal gland. The tumor was resected and histologically diagnosed as conventional DDLPS, in which dedifferentiated component was highly cellular and composed of pleomorphic anaplastic cells. After 3 years, the tumor recurred in the right retroperitoneal space...

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...

Rhabdomyosarcoma is the malignant neoplasm of striated muscle and a relatively uncommon tumor of the oral cavity. Embryonal variety is the most common subtype, observed in children below 10 years of age but occasionally seen in adolescents and young adults. The present report describes a case of embryonal rhabdomyosarcoma in the left posterior buccal mucosa, with extension in the adjacent alveolus, soft palate, oropharynx and nasopharynx of a 17-year-old female.

INTRODUCTION: Rhabdomyosarcoma has known as a highly malignant soft tissue sarcoma. It has been the most common soft tissue sarcoma in childhood, accounting for about 3 to 4 % of all cases of childhood cancer. Rhabdomyosarcoma was rare in adults, accounting for 3% of all soft-tissue sarcomas. embryonal rhabdomyosarcoma of female genital tract including uterine cervix in an adult was rare. CASE PRESENTATION: This study has reported a 33-year-old woman presented with abnormal vaginal discharge...

OBJECTIVE: To report three cases of embryonal rhabdomyosarcoma (ERMS) of the cervix in young women successfully treated with fertility-sparing surgery and chemotherapy. METHODS: Between January 2014 and December 2015, three cases of ERMS of the cervix were confirmed in young women at a single tertiary cancer center. All cases were managed by a pediatric oncologist and a gynecologic oncologist with a combination of surgery and chemotherapy. Fertility-sparing surgeries (cervical conization or robotic-assisted radical trachelectomy) were offered to patients depending on the tumor size...

INTRODUCTION: Rhabdomyoscarcoma (RMS) is the most common soft-part tumour in children, however, it is infrequent in adults. Thyroid involvement is exceptional and only four cases have been reported: two primary RMS in children and another two cases in young adults with RMS metastasis to the thyroid. We report the first case in the literature of a primary adult RMS with thyroid involvement and superior vena cava syndrome. CASE PRESENTATION: A 67-year-old male was admitted for an oedema of the arm extending to the laterocervical region...

The definition of soft tissue and bone sarcomas include a large group of several heterogeneous subtypes of mesenchymal origin that may occur at any age. Among the different sarcomas, rhabdomyosarcoma, synovial sarcoma, Ewing sarcoma and osteosarcoma are aggressive high-grade malignancies that often arise in adolescents and young adults. Managing these malignancies in patients in this age bracket poses various clinical problems, also because different therapeutic approaches are sometimes adopted by pediatric and adult oncologists, even though they are dealing with the same condition...

To design the services for adolescents and young adults (AYAs) with cancer, we need to understand the patterns of disease and the other clinical and managerial challenges of the patient group. Cancer occurring between the ages of 15 and 39 years is 4 times less rare than cancer occurring during the first 15 years of life and consists of 2% of all invasive cancer in Europe, about 66,000 patients in Europe each year. AYAs have a unique distribution of cancer types, including the peak in incidence of Hodgkin lymphoma (HL) or germ cell tumors...

INTRODUCTION: Benign prostatic hyperplasia (BPH) is generally common in men older than 50 years of age but is extremely rare in childhood. In the literature to date, fewer than five cases have been reported under 18 years of age. Owing to the limited number of cases, the etiology and management of BPH in the first two decades is not clear. OBJECTIVE: We herein report a 17-year-old boy who presented with acute urinary retention due to BPH and was treated with endoscopic transurethral resection of the prostate (TUR-P)...
