Abstract
Background Myoepithelial tumors have been widely described as a rare form of salivary gland neoplasm, although currently soft-tissue phenotypes have also been identified. These are tumors composed entirely of myoepithelial cells that exhibit a dual epithelial and smooth muscle phenotype. The occurrence of myoepithelial tumors within the central nervous system is also extremely rare, with only a few cases reported. Treatment options include surgical resection, chemotherapy, radiotherapy, or a combination of these approaches. Case Description The authors present a case of soft-tissue myoepithelial carcinoma with an unusual brain metastasis, rarely described in the literature. The purpose of this article is to present an update on the diagnosis and treatment of this pathology when affecting the central nervous system, through the review of the current evidence. Conclusion However, despite complete surgical resection, there is about a significative high rate of local recurrence and metastasis. Careful patient follow-up and staging is essential for better characterization and understanding of this tumor's behavior.

Abstract
Myoepithelial carcinoma, also known as malignant myoepithelioma, is considered an extremely rare (0.45-1%) malignant salivary gland neoplasm. Approximately 100 cases have been reported in the English-language literature on myoepithelial carcinoma. The majority of the myoepitheliomas described in the literature have been benign, and the malignant counterpart is considered rare (<1%). Such a tumor may appear de novo or rarely develop from a preexisting pleomorphic adenoma (<20%), and in exceedingly rare cases (<0.5%), it has arisen from a benign myoepithelioma (i.e., plasmacytoid myoepithelioma). To our knowledge, no case of myoepithelial carcinoma of the parotid gland arising in a plasmacytoid myoepithelioma synchronized with melanoma has been reported to date. The treatment of myoepithelial carcinoma has been mainly surgical, including wide excision with free margins, with or without nodal dissection. The roles of chemotherapy and radiotherapy have not yet been established. We report a case of myoepithelial carcinoma of the parotid gland arising in a plasmacytoid myoepithelioma synchronized with melanoma in a 40-year-old woman. In our case, a complete response was achieved with surgery followed by adjuvant chemotherapy based on carboplatin and paclitaxel concurrent with radiotherapy.

Abstract
Myoepithelial carcinoma of the breast is an extremely rare tumor composed entirely of malignant spindle cells with myoepithelial differentiation. The majority of previously reported cases have mainly described the clinicopathological features of the disease, and few have presented cytogenetic data. We herein present the case of a 48-year-old woman who was admitted with a left-sided breast lump in the inner upper quadrant that was initially diagnosed as a myoepithelioma with potentially malignant disorder. At 12 months after resection, she complained about a newly developed solid mass in the subareolar region of the ipsilateral breast that was diagnosed as an invasive ductal carcinoma. In addition, 16 months after the initial admission, a re-growing remnant lesion recurred in the inner upper quadrant and was ultimately diagnosed as a myoepithelial carcinoma. Lymph node metastasis of the myoepithelial carcinoma was also observed in her left axillary region 11 months after local recurrence. A cytogenetic analysis showed recurring specific chromosomal alterations both in the locally recurrent and in the lymph-node metastatic lesion: 48, XX, t(5;18)(q13;q23),del(6)(q?),+14. + mar1. To our knowledge, this is the first published report of clonal chromosomal rearrangements in myoepithelial carcinoma of the breast that presented as metachronic double cancer with invasive ductal carcinoma in the ipsilateral breast.

Abstract
To illustrate the role of p63 and its truncated variants in salivary gland tumors, 23 consecutive tumors and 6 normal salivary glands were studied immunohistochemically with anti-p63 antibody and by reverse transcriptase (RT) and nested polymerase chain reaction (PCR) to detect p63 isoform expression. Normal salivary glands: p63 antibody-stained basal and myoepithelial cells; by RT and nested PCR, the 2 main isoforms were present, whereas ΔNp73L was absent. Tumors: p63 antibody was positive in the following: Warthin tumor (WT) (3/3), oncocytoma (OC) (1/1), pleomorphic adenoma (PA) (7/7), polymorphous-low-grade adenocarcinoma (PLGA) (3/3), adenoid-cystic carcinoma (ADCC)(3/4), epithelial-myoepithelial-cell carcinoma (EMC) (1/1), and myoepithelial-cell carcinoma (MCC) (1/1). By RT and nested PCR all tumors expressed p63 irrespective of their morphologic differentiation. The ΔNp73L isoform was present in tumoral tissue but absent in normal salivary gland. These data suggest that p63, particularly its splice variant ΔNp73L, is involved in the neoplastic transformation of salivary glands.

Abstract
Myoepitheliomas are rare tumours that originate from glandular tissues such as the parotid or salivary glands, and less commonly from soft tissues of the head, neck, and other parts of the body. Intraorbital myoepitheliomas generally arise from the lacrimal gland. Intracranial myoepitheliomas are rare. We report a myoepithelioma of the orbital apex that did not originate from the lacrimal gland. It extended to the middle cranial fossa from the orbital apex and involved the dura and adjacent bone. A diagnostic biopsy via a lateral orbitotomy preceded resection. We review the natural course and histopathology of myoepithelial neoplasms, the surgical nuances of approaching an orbital apex tumour with maximal functional preservation, and the optimal management practices of these rare lesions.

Abstract
Background Malignant myoepithelioma is a relatively rare malignant tumor occurring most frequently in the salivary glands. A few isolated cases have been described in other locations, including soft tissue, bone, lung, bronchus, oral cavity, nasopharynx, larynx, and maxillary sinus. Malignant myoepithelioma, however, is uncommonly involved within the cavernous sinus. To the best of our knowledge, this is the first report of malignant myoepithelioma arising from within the cavernous sinus. Case presentation Herein, we report a case of a 48-year-old woman who presented a 1-month history of diplopia and blepharoptosis as well as radiological evidence of a rapidly developing cavernous sinus tumor. The patient underwent a trans-sphenoidal biopsy and a histological diagnosis indicated a malignant myoepithelioma. After diagnosis, the tumor grew rapidly and her clinical condition deteriorated progressively. Therefore, a pterional craniotomy with partial tumor removal was performed. The patient’s clinical state was worsened, and she died two months after the initial operation. Because the malignant myoepithelioma could not be traced to an organ of origin, other than the cavernous sinus, this case was diagnosed as a primary intracranial malignant myoepithelioma. Conclusion The purpose of presenting this case report is to raise awareness among clinicians to consider malignant myoepithelioma as a differential diagnosis when a cavernous sinus mass is identified. Furthermore, an ideal management strategy for malignant myoepithelioma is not known and the prognosis seems to be unfavorable; therefore, more cases are needed to enhance our knowledge of the diagnosis, treatment, and prognosis of this rare intracranial lesion.

Abstract
OBJECTIVES The aim of this study was to present a rare neoplasm, Primary myoepithelial carcinoma arising from the palate, and to review its diagnostic criteria, pathologic and clinical characteristics, treatment options and prognosis. CLINICAL PRESENTATION AND INTERVENTION Myoepitheliomas are tumors arising from myoepithelial cells mainly or exclusively. Myoepitheliomas mostly occur in salivary glands, as well as in breast, skin, and lung. Case of myoepitheliomas in palate has rarely been reported. Myoepithelial carcinoma is malignant counterpart of myoepitheliomas. Adenomyoepithelioma is also a different disease from myoepitheliaomas. Immunohistochemically, tumor cells of myoepithelial carcinoma express not only epithelial markers such as cytokeratin, epithelial membrane antigen (EMA), but also markers of smooth muscle origin such as calponin. The immunohistochemical criteria of myoepithelial differentiation are double positive for both cytokeratins and one or more myoepithelial immunomarkers (i.e., S-100 protein, calponin, p63, GFAP, maspin, and actins). Myoepithelial carcinomas of salivary and breast demonstrate copy number gains and gene deletion. The overall prognosis of myoepithelial carcinoma is poor. There is rarely recurrence or metastasis in benign myoepithelial tumors. Complete excision with tumor-free margin is always the preferred treatment, while local radiation therapy and chemotherapy are suggestive treatment options. Here, a rare case of myoepithelial carcinoma arising from the palate has been described and discussed for the treatment and outcome. Pathological and clinical characters of myoepitheliomas are also compared and discussed. CONCLUSION The case report serves to increase awareness and improve the index of diagnosis and treatment of myoepitheliomas.

Abstract
Salivary gland myoepithelial tumors are relatively uncommon tumors with an unpredictable clinical course. More knowledge about their genetic profiles is necessary to identify novel predictors of disease. In this study, we subjected 27 primary tumors (15 myoepitheliomas and 12 myoepithelial carcinomas) to genome-wide microarray-based comparative genomic hybridization (array CGH). We set out to delineate known chromosomal aberrations in more detail and to unravel chromosomal differences between benign myoepitheliomas and myoepithelial carcinomas. Patterns of DNA copy number aberrations were analyzed by unsupervised hierarchical cluster analysis. Both benign and malignant tumors revealed a limited amount of chromosomal alterations (median of 5 and 7.5, respectively). In both tumor groups, high frequency gains (> or =20%) were found mainly at loci of growth factors and growth factor receptors (e.g., PDGF, FGF(R)s, and EGFR). In myoepitheliomas, high frequency losses (> or =20%) were detected at regions of proto-cadherins. Cluster analysis of the array CGH data identified three clusters. Differential copy numbers on chromosome arm 8q and chromosome 17 set the clusters apart. Cluster 1 contained a mixture of the two phenotypes (n = 10), cluster 2 included mostly benign tumors (n = 10), and cluster 3 only contained carcinomas (n = 7). Supervised analysis between malignant and benign tumors revealed a 36 Mbp-region at 8q being more frequently gained in malignant tumors (P = 0.007, FDR = 0.05). This is the first study investigating genomic differences between benign and malignant myoepithelial tumors of the salivary glands at a genomic level. Both unsupervised and supervised analysis of the genomic profiles revealed chromosome arm 8q to be involved in the malignant phenotype of salivary gland myoepitheliomas.

Abstract
A case of epithelioid hemangioendothelioma of the cauda equina is reported. The patient presented with rapidly worsening low back pain. Magnetic resonance imaging revealed a sharply demarcated intradural lumbar lesion. A bluish-red lesion, attached to the filum terminale, was removed. The patient is alive without evidence of recurrence 18 months after surgery. The tumor was composed of variously sized vessels lined by epithelioid endothelial cells with clear cytoplasm and centrally located, moderately atypical nuclei. These cells were immunoreactive for CD31 and factor VIII antibodies. Cytogenetic analysis disclosed two clones: 44-45X, - Y [cp3]/46XY[11]. Epithelioid hemangioendothelioma may arise in several sites, the most common being soft tissues. It is a borderline tumor that may recur, may metastasize, and rarely causes death. The present case appears to be the first example of epithelioid hemangioendothelioma of the spinal cord.
