The testis has long enjoyed a reputation as an immunologically privileged site based on its ability to protect auto-antigenic germ cells and provide an optimal environment for the extended survival of transplanted allo- or xeno-grafts. Exploration of the role of anatomical, physiological, immunological and cellular components in testis immune privilege revealed that the tolerogenic environment ...

Myoid hamartomas of the breast are extremely rare breast lesions, with a poorly understood pathogenesis. We describe the case of a 38-year-old premenopausal woman who presenting with a mass in the left breast. Mammography revealed an oval mass that was partly indistinct, and ultrasonography showed a hypoechoic mass with a slightly irregular margin. Bilateral breast dynamic magnetic resonance im...

Myopericytoma is a benign tumor that is composed of myoid-appearing oval to spindle-shaped cells with a concentric perivascular pattern of growth. The tumor is morphologically heterogeneous and can exhibit a broad histologic spectrum. We describe a case of multiple myopericytoma occurring in the head and neck skin region with involvement of the parotid gland where it is known to occur very rare...

Myopericytoma is a recently proposed term to describe a group of tumors that originate from perivascular myoid cells and show a range of histological growth patterns. The tumor typically arises within subcutaneous tissues of extremities. Only a small number of cases describing myopericytoma in the oral cavity have been reported. Though rare, myopericytoma should be included in the differential ...

Epithelioid angiomyolipoma (EAML) is a rare renal mesenchymal tumor with malignant potential and is frequently associated with tuberous sclerosis complex (TSC). As metastasis of the tumor cells occur early, EAML is considered a potentially malignant tumor type and intrigues further research on it. Under the microscope, we could find the tumor was composed of atypical polygonal cells sheet mixed...

Members of the pre-B-cell leukemia transcription factor (PBX) family homeoproteins are mainly known for their involvement in hematopoietic cell differentiation and development leukemia. The four PBX proteins, PBX1, PBX2, PBX3 PBX4, belong to three amino acid loop extension (TALE) superfamily which important transcriptional cofactors several developmental processes involving homeobox (HOX) facto...
