1/27. Hepatocellular carcinoma metastatic to the oral mucosa: report of a case with multiple gingival localizations.BACKGROUND: Metastases to the oral mucosa are rare, representing less than 1% of the tumors at this site. Most of these metastatic neoplasms originate in the lungs, kidneys, and liver. methods: The clinicopathologic features of an occult hepatocellular carcinoma, metastatic to the oral mucosa, are reported. The patient, a 70-year-old male, complained of 3 distinct polypoid, reddish lesions of the antero-inferior alveolar crest and both the right and left postero-superior attached gingiva, without bone involvement. The lesions were excised, with the clinical diagnosis of multiple vascular tumors, formalin-fixed, paraffin-embedded, cut and stained with hematoxylin and eosin. Consecutive sections were immunostained for alpha-1-antichymotrypsin, CEA, cytokeratins, EMA, hepatocyte antigen, PSA, S-100 protein, and thyroglobulin, using the alkaline phosphatase/anti-alkaline phosphatase technique. RESULTS: The morphologic features of the lesions were consistent with the diagnosis of carcinoma with trabecular and glandular patterns and bile secretion; furthermore, immunohistochemical reactivity for alpha-1-antichymotrypsin, cytokeratins, CEA, EMA, and hepatocyte antigen was demonstrated and the hepatic origin of the tumor was postulated. ultrasonography demonstrated a liver mass, which was biopsied and treated by chemoembolization. While no further complications occurred in the oral mucosa, the patient died 8 months after the diagnosis for widespread diffusion of the tumor to the lungs and brain. CONCLUSIONS: This case emphasizes the need to include metastatic tumors in the differential diagnosis of atypical neoplasms of the oral mucosa and to evaluate the opportunity of surgical treatment in order to preserve the functions of the mouth, even if the prognosis of the primary tumors remains unfavorable.- - - - - - - - - - ranking = 1keywords = mouth (Clic here for more details about this article) |
2/27. Three cases of palatal polyps in infants.Fibrous lesions are common in the oral cavity, however, in infants they are rarely reported. We present three cases of palatal polyps in infants aged 2 days, 3 months and 7 months. In two cases, the treatment was surgical removal and in one case the polyp decreased in size and surgical removal was not required. In two infants, the diagnosis was confirmed histologically as fibroepithelial hyperplasia.- - - - - - - - - - ranking = 4.2061392419446keywords = oral cavity, cavity (Clic here for more details about this article) |
3/27. Endometrial stromal sarcoma of the uterus: MR and US findings.We describe the MRI and US features of two patients with endometrial stromal sarcoma of the uterus. Both lesions appeared as voluminous polypoid masses within an expanded endometrial cavity on both US and MRI. They had mixed echo-texture and heterogenous signal intensity on both T1- and T2-weighted sequences. T2-weighted images were most helpful in detecting the endometrial nature of the disease and its relationships with surrounding myometrium.- - - - - - - - - - ranking = 0.57213550848145keywords = cavity (Clic here for more details about this article) |
4/27. Adenomyomatous polyp mimicking hydatidiform mole on ultrasonography.The authors present a case report of a 62-year-old woman who experienced irregular genital bleeding. Although the serum hCG level was extremely low, transvaginal ultrasonography revealed vesicle pattern in the uterine cavity, suggesting trophoblastic disease. hysterectomy was performed and histological diagnosis was adenomyomatous polyp. To our knowledge, this is the first report that the adnomyomatous polyp can demonstrate the vesicle pattern on ultrasonography.- - - - - - - - - - ranking = 0.57213550848145keywords = cavity (Clic here for more details about this article) |
5/27. Aggressive angiomyxoma presenting as polyp of uterine cavity.Aggressive angiomyxoma is a distinctive, locally aggressive tumor associated with a high risk of local recurrences that lacks metastatic potential. This tumor occurs mostly in the soft tissues of the pelvis and the perineum of adult women. It may rarely occur at less common sites, such as the vagina, urinary bladder, and soft tissue of the perineum and the perianal region in men, particularly the scrotum. We report a case of aggressive angiomyxoma presenting as an endometrial uterine polyp. To the best of our knowledge, the primary location of aggressive angiomyxoma within the uterine cavity has never been described. Immunohistochemical and ultrastructural findings support the conclusion that the progenitor cell displays myofibroblastic and fibroblastic features, with a capacity for smooth muscle differentiation.- - - - - - - - - - ranking = 2.8606775424073keywords = cavity (Clic here for more details about this article) |
6/27. Fibrovascular polyp of the esophagus in infant.A five month female was referred complaining of intermittent vomiting with protrusion of a sausage-like mass through the oral cavity. Esophageal endoscopy and esophagogram revealed a mass in the upper esophagus, which was diagnosed as a fibrovascular polyp. Under general anesthesia, the mass was grasped through the oral cavity with a forcep and ligated and excised at the base, where a stump arose from the posterior wall of the cervical esophagus. The pathology was confirmed as a fibrovascular polyp, which is a rare benign esophageal lesion occurring mostly in adult males, and has not been reported in infancy.- - - - - - - - - - ranking = 8.4122784838893keywords = oral cavity, cavity (Clic here for more details about this article) |
7/27. Cerebral heterotopia appearing as an extranasal polyp.Cerebral heterotopia represents a rare tumorlike lesion related in its development to the encephaloceles but differing from these by non-connection to the cranial cavity. We describe an unusual case of cerebral heterotopia appearing as a pedunculated polyp on the upper lip of a newborn. As the distinction between encephaloceles and cerebral heterotopias is based on the correlation of radiologic and clinical findings, the surgical treatment of tumorlike lesions of the nasal and pharyngeal region in children requires a careful preoperative evaluation of their possible connection to the cranial cavity.- - - - - - - - - - ranking = 1.1442710169629keywords = cavity (Clic here for more details about this article) |
8/27. The anaesthetic management of a case of severe upper airways obstruction due to an enlarging subglottic benign polyp.The use of a newly developed aid to jet ventilation of the lungs, a modified Ben-Jet tube (the Hunsaker Monjet tube), is described in a patient with partial upper airway obstruction. This report highlights an unusual use of this device. The Monjet is a fluoroplastic, monitored, self-centring, fine bore tube that can be inserted from the mouth through to the subglottic region. It was originally developed to anaesthetize healthy patients without airway obstruction who were undergoing suspension microlaryngoscopy.- - - - - - - - - - ranking = 1keywords = mouth (Clic here for more details about this article) |
9/27. Hairy polyps of the nasopharynx.Hairy polyps are rare tumours that can occur anywhere in the body. They are especially rare inthe pharynx. We report two cases of hairy polyps which originated from the nasopharynx. One presented with intermittent obstruction of the airway and the second presented as a visible pedunculated mass protruding from the mouth of a neonate.- - - - - - - - - - ranking = 1keywords = mouth (Clic here for more details about this article) |
10/27. Giant fibrovascular polyp of the esophagus. A lesion causing upper airway obstruction and syncope.Giant fibrovascular polyp of the esophagus is a rare but dramatic entity. These large polyps arise in the proximal esophagus and can cause airway obstruction secondary to mechanical pressure on the larynx, or they can present as a mass that is regurgitated into the oral cavity. We present a 66-year-old man who complained of nausea and vomiting that were associated with a fibrovascular polyp protruding into the mouth. He had also experienced several episodes of syncope resulting from intermittent airway obstruction. He underwent an open resection of an 11.8-cm fibrovascular polyp and an endoscopic resection of a second fibrovascular polyp 2 days later. Histopathologically, both masses were composed of a mixture of mature adipose tissue lobules and fibrovascular tissue, lined by reactive squamous epithelium. Despite their large size, giant fibrovascular polyps should be recognized radiologically and pathologically as benign lesions. However, they can result in significant morbidity.- - - - - - - - - - ranking = 5.2061392419446keywords = oral cavity, mouth, cavity (Clic here for more details about this article) |
