Malignant mesothelioma of the tunica vaginalis constitutes a very rare but often fatal malignancy of the male genitalia. This diagnosis should be suspected in patients exposed to asbestos and those presenting with clinical symptoms of either hydrocele or inguinal hernia. We report here a case of malignant mesothelioma of the tunica vaginalis. A 69-year-old man with a left hydrocele and inguina...
Abstract BACKGROUNackground and aimD & AIM: Keratinized odontogenic cyst is a developmental odontogenic cyst that is mainly due to dental lamina. This cyst has the nature of local invasion and high recurrence. There are several therapeutic measures to control the recurrence of this cyst in studies. One of the conservative approaches is to use an enucleation followed by decompression techn...
Dermatofibrosarcoma protuberans (DFSP) is a rare coetaneous sarcoma that originates from fibroblasts of dermis and presents as a non tender coetaneous nodule. Local slow invasion, recurrence after therapy and low risk of metastasis are its main specifications. Pathology and immunohistochemistry are used to diagnose and wide surgery is the best approach for treatment. We present a case of recu...
We summarize the current knowledge on parasitism-related invasion processes of the globally invasive Rattus lineages, originating from Asia, and how these invasions have impacted the local epidemiology of rodent-borne diseases. Parasites play an important role in the invasion processes and successes of their hosts through multiple biological mechanisms such as "parasite release," "immunocompete...
Neural invasion (NI) and severe pain are common features in patients with pancreatic cancer (PCa). Here, we present the case of a 67-year-old patient with PCa whose pre- and postoperative physical situation was clearly dominated by severe pain sensation. The resected pancreas specimen revealed severe and frequent NI by cancer cells. Seven months after R1 resection and additive chemotherapy, the...
Changing marine temperatures modify the distributional ranges of natural populations, but the success of invasion of new areas depends on local physical and ecological conditions. We explore the invasion by thermophilic species and their ecosystem effects by simulating a sea surface temperature (SST) increase using a trophodynamic model for the northern Adriatic Sea (NAS), in which thermal and ...
BACKGROUND The purpose of this study was to investigate the prognostic factors for salvage nasopharyngectomy. METHODS A retrospective review was conducted on maxillary swing nasopharyngectomy performed between 1998 and 2010. Univariate and multivariate analyses identified prognostic factors affecting actuarial local tumor control and overall survival. RESULTS The median follow-up duration w...
These patients have a poor prognosis, as the lesions usually present with jaundice due to invasion and obstruction of the duct. They spread to surrounding tissues, including the portal vein and lymph nodes, metastasize to the liver, and can be multifocal, particularly with PSC. Staging of the disease is performed with CT or MRI. Endoscopic ultrasound can outline invasion into the biliary duct a...
