Calcifying odontogenic cyst (COC) is a unique odontogenic lesion with combined features of a cyst and neoplasm.  This lesion shows a great diversity in its clinicopathological behavior.  It may become aggressive and rarely malignant.  This case is an aggressive COC of the maxilla in a young male patient which recurred after several radical surgical excisions.  Eventually invading the cranium, t...

BACKGROUND To investigate the relationship between paraglottic space (PGS) invasion and lymph node metastasis in patients undergoing supracricoid partial laryngectomy. METHODS The study included 98 subjects with squamous cell carcinoma of the glottis. RESULTS The PGS invasion rate was 60.2% (59/98), and a significant correlation was found between PGS invasion and cervical lymph node metasta...

Initial imaging of pancreatic ductal adenocarcinoma is of crucial importance in the decision-making process. The aim of this study was to compare preoperative imaging, pathological data, and outcomes in a series of patients who underwent resection for pancreatic head cancer.From January 2004 to December 2009, data were collected by the Association Française de Chirurgie on 1044 patients who rec...

OBJECTIVE To determine if perineural invasion (PNI) of small nerves affects the outcome of patients with squamous cell carcinoma (SCC) of the upper aerodigestive tract. DESIGN Retrospective clinicopathological study of patients with at least 2 years of follow-up and with negative margins and no prior, synchronous, or metachronous SCC. SETTING Academic otolaryngology department. PATIENTS O...

Lymphovascular space invasion was shown to play a key role in the progression of cervical cancer. Because of the absence of a specific marker for lymphatic vessels, earlier studies could not reliably distinguish between blood and lymphatic vessel invasion. By immunostaining for podoplanin, a novel marker for lymphatic endothelium, and for factor VIII-related antigen, we determined lymphatic and...

BACKGROUND To assess the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of intraoperative gross examination (IGE) of uterine specimens in determining deep myometrial invasion and cervical invasion compared to final histology. MATERIALS AND METHODS The clinical, surgical and histological data of all FIGO stage I-II endometrial cancer (E...
