4. In most cases, the enucleation can be carried out intraorally, as clearly evident in a review of international bibliography, which found that in 120 cysts surgically treated, 70 (58%) were done intraorally, 37 (31%) extraorally, and 13 (11%) via a combination of intra and extraoral approaches 6. Effective treatment of dermoid and teratoid cyst of the floor of the mouth requires identificatio...

Adrenocortical carcinoma (ACC) is a rare, but highly aggressive type of tumor with an incidence of one to two per million annually. Adrenocortical carcinosarcoma is an exceptional variant of ACC, which is characterized by the presence of histological regions of carcinoma and sarcoma. To date, to the best of our knowledge, there have only been 12 reported cases of adrenocortical carcinosarcoma. ...

AIM The aims of this study were to perform clinicopathological analyses of teratoid cysts of the floor of the mouth and to assess the possibility of surgical treatment. MATERIALS AND METHODS The incidence, manifestations, histogenesis, treatment and prognosis of 10 patients admitted to our department between April 2000 and May 2008 were reviewed. RESULTS Teratoid cysts occurred almost ex...

BACKGROUND Carcinosarcoma of the lung is a rare malignant neoplasm. We evaluated the diagnosis and treatment of six carcinosarcoma cases, including a synchronous tumour and a solitary pulmonary tumour, along with the clinical and histological features and survival times. METHODS From a retrospective analysis of 1076 non-small-cell lung cancer resections performed between January 1996 and Janu...

Medulloepithelioma is a rare congenital tumor of the ciliary body and iris. The current classification and grading of medulloepithelioma shows inconsistencies and does not reflect clinical behavior. This position paper discusses the backgrounds of the current classification and intends to initiate a discussion on an alternative classification and grading scheme. © 2016 The Author(s) Published b...

Pediatric brain tumors including medulloblastoma and atypical teratoid/rhabdoid tumor are associated with significant mortality and treatment-associated morbidity. While medulloblastoma tumors within molecular subgroups 3 and 4 have a propensity to metastasize, atypical teratoid/rhabdoid tumors frequently afflict a very young patient population. Adjuvant treatment options for children suffering...

PURPOSE To analyze the prognostic factors for survivals and to evaluate the impact of postoperative whole pelvic radiotherapy (WPRT) on pelvic failure in patients with uterine sarcoma treated with radical surgery. MATERIALS AND METHODS We retrospectively analyzed 75 patients with uterine sarcoma who underwent radical surgery with (n = 22) or without (n = 53) radiotherapy between 1990 and 2010...

 Carcinosarcoma is a rare type of cancer that is composed of a mixture of sarcomatous and carcinomatous elements. Pulmonary carcinosarcoma has a 25% five-year survival rate with a prognosis poorer than other non-small cell lung carcinomas. Herein, we report a case of pulmonary carcinosarcoma and its 18F-FDG PET/CT findings. A 61-year-old male patient presented with brain symptoms, including hea...

PURPOSE To evaluate the expression levels of claudin-3 and claudin-4, the low- and high-affinity receptors, respectively, for the cytotoxic Clostridium perfringens enterotoxin (CPE) in uterine carcinosarcomas and explore the potential for targeting these receptors in the treatment of this aggressive uterine tumor. EXPERIMENTAL DESIGN We analyzed claudin-3 and claudin-4 receptor expression at ...

A unique teratoid medulloepithelioma showing a conspicuous vascular component with orbital involvement is described.
