We report 5 cases of primary intradermal nodular unpigmented tumors with a melanocytic immunophenotype associated with a novel CRTC1-TRIM11 fusion. Clinically, the cutaneous nodules were slowly growing in 3 women and 2 men (25 to 82 y old, median, 28 y) with no specific topography. Lesion size ranged from 4 to 12 mm (median, 5 mm). The tumors were strictly located in the dermis with a nodular pattern. The cells were arranged in confluent nests and fascicules. Central fibronecrotic areas were present in 2 cases...

Central nervous system high-grade neuroepithelial tumors with BCOR alteration (CNS HGNET-BCOR) are a recently reported rare entity, identified as a small fraction of tumors previously institutionally diagnosed as so-called CNS primitive neuroectodermal tumors. Their genetic characteristic is a somatic internal tandem duplication in the 3' end of BCOR (BCOR ITD), which has also been found in clear cell sarcomas of the kidney (CCSK) and soft tissue undifferentiated round cell sarcomas/primitive myxoid mesenchymal tumors of infancy (URCS/PMMTI), and these BCOR ITD-positive tumors have been reported to share similar pathological features...

INTRODUCTION: The incidence and clinical significance of lymph node metastasis (LNM, N1) in soft tissue sarcoma (STS) is unclear. Recent studies have focused on extremity/trunk STS (ETSTS). We sought to define the subgroup of patients with LNM at sarcoma diagnosis across all disease sites and histologies. METHODS: We identified and categorized 89,870 STS patients from the National Cancer Data Base (1998-2012) by nodal stage. Pathologically confirmed LNM (pN1) were identified in 1404 patients; 1750 had clinically suspicious but not pathologically confirmed LNM (cN1)...

Malignant gastrointestinal neuroectodermal tumor (GNET) is a rare malignant tumor. It is also referred to as clear cell sarcoma-like gastrointestinal tumor (CCSLGT). It is an aggressive tumor with a high rate of local recurrence, metastases, and early death from disease. Its pathogenesis is not known. It shows evidence of neural differentiation and lacks immunohistochemical and ultrastructural evidence of melanocytic differentiation. It needs to be distinguished from various mimickers owing to its aggressive course...

Endometrial stromal sarcomas (ESSs) are mesenchymal uterine tumors characterized by recurrent genetic events, most commonly chromosomal rearrangements, that create oncogenic gene fusions. High-grade endometrial stromal sarcomas (HG-ESSs), as defined in the 2014 World Health Organization Classification, typically contain oncogenic YWHAE-NUTM2 fusions; however, although not well characterized, there are tumors morphologically overlapping with HG-ESS that do not contain the YWHAE-NUTM2 fusions. These fusions are also found in certain pediatric primitive sarcomas, including clear cell sarcoma of the kidney and soft tissue undifferentiated round cell sarcoma of infancy...

Clear cell sarcoma (CCS) is an aggressive mesenchymal malignancy characterized by the unique chimeric EWS-ATF1 fusion gene. Patient-derived cancer models are essential tools for the understanding of tumorigenesis and the development of anti-cancer drugs; however, only a limited number of CCS cell lines exist. The objective of this study was to establish patient-derived CCS models. We established patient-derived CCS models from a 43-yr-old female patient. We prepared the patient-derived xenografts (PDXs) from tumor tissues obtained through biopsy or surgery and isolated stable cell lines from PDXs and the original tumor tissue...

Skin tumors are a clinically heterogeneous group of dermatologic conditions that affect both children and adults. Although similar types of skin tumors can affect both children and adults, the epidemiology, pathogenesis, and treatment of these skin neoplasms can vary drastically in children compared with adults. Despite the clear need for literature elucidating the differences of skin tumors in children compared with adults, there is a serious dearth of scientific contributions addressing this area. This contribution highlights the types of differences that can occur between adults and children with skin neoplasms, as well as the special considerations that need to be recognized when managing skin tumors in children by providing a comparative analysis of basal cell carcinoma, squamous cell carcinoma, and Kaposi sarcoma occurring in adults with these same tumors occurring in children...

Doxorubicin is a commonly used chemotherapeutic employed to treat multiple human cancers, including numerous sarcomas and carcinomas. Furthermore, doxorubicin possesses strong fluorescent properties that make it an ideal reagent for modeling drug delivery by examining its distribution in cells and tissues. However, while doxorubicin fluorescence and lifetime have been imaged in live tissue, its behavior in archival samples that frequently result from drug and treatment studies in human and animal patients, and murine models of human cancer, has to date been largely unexplored...

Several primary pathologic entities in diverse anatomic locations have the potential to simulate metastatic neoplasms histologically. Their misinterpretation as such may result in needless and extensive clinical evaluations that are intended to detect a presumed malignancy at another site. More importantly, mistakes of this type can deprive patients of surgical excisions that could be curative. This presentation considers a review of selected primary lesions that can simulate metastases. They include hemangioblastoma, glioblastoma and meningioma with epithelial metaplasia, choroid plexus carcinomas, primary neuroendocrine carcinomas in unusual locations, special forms of sinonasal and salivary glandular adenocarcinoma, clear-cell thyroid carcinomas, unusual microscopic subtypes of pulmonary adenocarcinoma, epithelioid myomelanocytomas ("sugar tumors"), mesotheliomas, primary thymic carcinomas, endodermal choristomas of the interatrial myocardium, peripheral cholangiocarcinoma, adrenocortical carcinoma, adenocarcinomas of the urinary bladder, mucinous and "rhabdoid" tumors of the ovaries, rete testis adenocarcinomas, interdigitating dendritic-cell sarcoma of lymph nodes, selected sweat gland carcinomas, cutaneous Merkel cell carcinoma, primary dermal and subcutaneous melanoma, mucosal and visceral melanomas, epithelioid sarcoma, clear-cell sarcoma, and adamantinoma of long bones...

The differentiation status of tumors is used as a prognostic indicator, with tumors comprised of less differentiated cells exhibiting higher levels of aggressiveness that correlate with a poor prognosis. Although oncogenes contribute to blocking differentiation, it is not clear how they globally alter miRNA expression during differentiation to achieve this result. The pediatric sarcoma Alveolar Rhabdomyosarcoma, which is primarily characterized by the expression of the PAX3-FOXO1 oncogenic fusion protein, consists of undifferentiated muscle cells...

OBJECTIVE: Pheochromocytomas and paragangliomas (PPGLs) are neuroendocrine tumors derived from adrenal or extra-adrenal locations, respectively. Upon suspicion of PPGL, specific metabolomic, molecular, biochemical, imaging, and histopathological studies are performed to prove, localize, treat, and monitor disease progression. Recently, improved diagnostic tools allow physicians to accurately diagnose PPGL, even in patients presenting with small (less than 1 cm) or biochemically silent tumors, which previously delayed proper detection and treatment...

We recently identified hypermethylation at the gene promoter of transcription factor 21 (TCF21) in clear cell sarcoma of the kidney (CCSK), a rare pediatric renal tumor. TCF21 is a transcription factor involved in tubular epithelial development of the kidney and is a candidate tumor suppressor. As there are no in vitro models of CCSK, we employed a well-established clear cell renal cell carcinoma (ccRCC) cell line, 786-O, which also manifests high methylation at the TCF21 promoter, with consequent low TCF21 expression...

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...

Proximal-type epithelioid sarcoma (ES) with a diffuse myxoid stroma is rare. Here, we report the case of a 33-year-old man with a perineal mass. Imaging demonstrated the presence of a poorly demarcated 6.9 × 5.3-cm mass in the subcutaneous perineal region. Macroscopic examination showed that the resected tissues were partially necrotic. Histological examination showed that the tumor comprised numerous large or pleomorphic epithelioid cells with large vesicular nuclei and prominent nucleoli. A clear background of necrosis and inflammatory exudates was also present...

Colorectal cancer (CRC) is the third most common cancer and the fourth most common cause of cancer-related death worldwide. Tumour progression and development in CRC is a multi-step process involving a large number of genetic and epigenetic alterations. Previous studies indicated that abnormally expressed microRNAs play critical roles in CRC through regulation of oncogenic and tumour-suppressor genes. Hence, determination of the function of microRNAs may provide novel therapeutic targets for CRC diagnosis and treatments...
