Malignant mixed tumors of salivary gland are extremely rare tumors defined by the presence of malignant epithelial and mesenchymal components together. We report here a case of carcinosarcoma arising from a recurrent pleomorphic adenoma of submandibular salivary gland in a 36 year old woman. Histology showed a monomorphic picture dominated by malignant mesenchymal component with mixed nature pr...

Malignant mixed müllerian tumor (MMMT) arising from female internal genitalia is rare with the uterine corpus being the most prevalently affected site. It is even more rare when it occurs on both uterus and ovary at the same time. We describe a case of synchronized occurrence of MMMT on ovary and uterine adenosarcoma with review of literature.

The carcinosarcoma is a malignant mixed müllerian tumor with a highly malignant, biphasic tumor consisting of both epithelial and mesenchymal components. The presented case refers to a patient in climax with a vaginal bleeding. The Doppler echography highlights a polypoid mass, which prolapses in the cervical channel. The histopathological and immunohistochemical analysis of the surgically rese...

We report a case of carcinosarcoma of the minor salivary glands of the left palatine tonsil, an especially rare location. Imaging characteristics assessed at CT, MR imaging, and angiography are presented. In addition, we describe our experience with preoperative therapeutic endovascular embolization of this hypervascular tumor.

AIM The aim of our study was to evaluate survival outcomes in malignant mixed Mullerian tumors (MMMT) of the uterus with respect to the role of cell cycle and apoptotic regulatory proteins in the carcinomatous and sarcomatous components. METHODS 23 cases of uterine MMMT identified from the Saskatchewan Cancer Agency (1970-1999) were evaluated. Immunohistochemical expression of Bad, Mcl-1, bcl...

Primary pleomorphic adenomas of the respiratory tract are rare tumors. They usually originate from the bronchial glands, but may also be unrelated to the bronchial tract and be localized in the pulmonary parenchyma. These salivary-gland type neoplasms have peculiar histological and clinical features: they usually behave as low-grade malignant neoplasms, but may also have more aggressive feature...

primary lymphomas of the lung are rare and usual radiographic findings are adenopathy, effusion, multiple lesions, solitary lesion or diffuse lesion. this paper presents a case of primary malignant tumor of the lung with a very rare radiological presentation. a 20-year-old male patient was admitted to our hospital due to fever, chills, productive cough and later development of hemoptysis. weigh...

background: mullerian adenosarcoma, a rare tumor, is composed of mixed mesenchymal and epithelial elements. the epithelial component is typically benign and admixed with malignant sarcomatous stroma. this tumor can be distinguished in approximately 8% of all uterus sarcomas and commonly originates in the endometrium as a growing polypoid mass in the uterine cavity. all age groups are affected b...

The interaction of normal, tumor-bearing, nonspecifically sensitized, and immunized syngeneic lymphocytes and the B16 melanoma was tested in vivo by experimental pulmo nary métastases. Various numbers of lymphocytes were mixed and incu bated with the tumor cells for 90 min on a rotating platform, and then the mixtures were injected i.v. into C57BL/6 mice. Normal, tumor-bearing, and nonspecific...

Benign mixed tumour of the skin (chondroid syringoma) is an uncommon skin adnexal tumour, usually presenting as a slow growing solitary painless nodule. The morphological appearances are similar to those of a pleomorphic adenoma of the salivary gland. Hair matrix and sebaceous differentiation can be seen in some lesions. Focal ossification is a rare finding. This report presents a case of a sim...
