1/141. Giant gas filled cysts of the sigmoid colon: a report of two cases.Two case reports of giant gas filled cysts of the sigmoid colon are presented. It is considered that radiology provides the only useful and conclusive diagnostic investigation. In one of the cases, operative confirmation was obtained. In the other, the radiological appearances are considered to be diagnostic.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/141. hiv-1 (p24)-positive multinucleated giant cells in HIV-associated lymphoepithelial lesion of the parotid gland. A report of two cases.BACKGROUND: Cystic benign lymphoepithelial lesion (CBLL) is a well-recognized parotid disorder the diagnosis of which can be made on the basis of clinical findings, human immunodeficiency virus (HIV) testing, image studies and fine needle aspiration (FNA). Most aspirations are cystic, and the lesion can be recognized if the triad of foamy macrophages, lymphoid and epithelial (squamous) cells is observed. CASES: The authors recently observed FNA cytologic features of two HIV-associated cases that exhibited numerous multinucleated giant cells (MGCs) but failed to show the epithelial component. A subsequent surgical resection was performed in one patient. Similarly to what has been described for nasopharyngeal (adenoid and tonsil) lymphoid tissue of HIV-positive patients, intense immunoexpression of S-100 and p24 (hiv-1) protein was present in MGC. CONCLUSION: The diagnosis of HIV-associated CBLL should always be considered if a parotid cystic lesion presents with numerous MGCs. Immunocytochemical detection of p24 (hiv-1) protein in MGC becomes a very useful diagnostic aid and extends to parotid CBLL many of those pathogenic features of hiv-1 infection already noted in other hiv-1-infected, lymphoid oropharyngeal lesions.- - - - - - - - - - ranking = 7.7184164731462keywords = giant, multinucleated, giant cell (Clic here for more details about this article) |
3/141. Giant orbital cyst after strabismus surgery.We describe the clinical, histopathologic, and radiologic findings and management of a patient who had a giant orbital cyst after reoperative strabismus surgery. In the case report, we describe, in detail, a giant orbital cyst developing on the medial side of the globe after the third operation for repair of strabismus. Imaging studies, including computed tomographic (CT) scan and orbital ultrasound, demonstrate the findings. The observations at surgery and the surgical pathologic condition of the cyst are described. The orbital cyst was successfully removed, advancing the remaining medial rectus muscle and recessing the lateral rectus muscle, which resulted in reduction of a large-angle exotropia to a small exodeviation. Adduction was improved but not normalized. The pathologic examination indicated a benign inclusion cyst of the conjunctiva with fibrosis and chronic inflammation. A possible cause of this type of cyst is an epithelial remnant inadvertently placed with the muscle substance during previous surgery.- - - - - - - - - - ranking = 2keywords = giant (Clic here for more details about this article) |
4/141. MR imaging of a hemorrhagic and granulomatous cyst of the ligamentum flavum with pathologic correlation.cysts of the ligamentum flavum are uncommon causes of neurologic signs and symptoms and usually are seen in persons over 50 years of age. We report a case of an epidural cyst located in the ligamentum flavum, which contributed to spinal stenosis in a 30-year-old man. Radiologic features were similar to those of a synovial cyst, but synovium was not identified histologically. The imaging and pathologic features were unusual, including hemorrhage and a fibrohistiocytic reaction with giant cells.- - - - - - - - - - ranking = 1.1213434218031keywords = giant, giant cell (Clic here for more details about this article) |
5/141. Combined hepatocellular and cystadenocarcinoma presenting as a giant cyst of the liver--a case report.Primary cystic lesions of the liver are very rare. Most of the solid tumours are hepatocellular carcinomas (HCC) with a smaller number being cholangiocarcinomas. The association of HCC with other primary liver malignancies is also extremely rare. This case report is about a 27 year old male patient who presented with a giant cystic lesion of the left liver. A CT scan showed a cystic lesion with internal septations and a thrombus in the main portal vein. The patient underwent an extended left hepatectomy and a portal venotomy with removal of the thrombus. Coexistent hepatocellular and cystadenocarcinoma were reported on histopathological examination. The patient was put on 5-FU postoperatively. He is doing well 11 months after surgery.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
6/141. Solitary unilocular cyst of the lung with features of persistent interstitial pulmonary emphysema: report of four cases.Neonatal interstitial pulmonary emphysema (IPE) is a well-characterized lesion usually presenting in preterm newborns as a complication of respiratory distress syndrome and/or assisted ventilation. Occasionally, IPE may occur spontaneously in infants with no underlying pulmonary disease. Persistence of IPE (PIPE) may be diffuse or localized. Localized PIPE usually presents as multiple cysts 0.3 to 3 cm in one or more lobes of the lung. In this report, we describe four cases of unilocular large cysts (up to 5 cm in diameter) partially lined by uni- and multinucleated histiocytes in a foreign body type reaction and showing gas dissection of the surrounding parenchyma (present in case 1). These histological features favored the diagnosis of PIPE and the cases were interpreted as such, since no other clear-cut diagnosis could be defined. However, because the lesion was limited to one lobe, and the children were full term, asymptomatic at birth and without history of respiratory distress or assisted ventilation, differential diagnosis with other pulmonary cystic lesions of infancy is mandated.- - - - - - - - - - ranking = 0.42233987282614keywords = multinucleated (Clic here for more details about this article) |

Giant blood cyst of the mitral valve.We report a rare case of giant blood cyst originating from the anterior mitral valve leaflet and chordae tendineae, which was incidentally discovered during a 2-dimensional echocardiography examination performed for assessment of left ventricular function after an uncomplicated myocardial infarction in a 50-year-old man.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
8/141. prenatal diagnosis of a fetal abdominal cyst.Hepatic liver cysts are rare and few cases have been described in the literature. Initially, these cysts are detected by a prenatal ultrasound as abdominal, and consequently, the final diagnosis of hepatic cysts is done during the postnatal period. We present a case of a giant hepatic cyst found incidently during a routine ultrasound examination. The diagnosis and management of a fetal intraabdominal cyst is discussed.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
9/141. Huge omental cyst mimicking ascites.An unusual case of omental cyst is described. A 4-year-old child presenting as abdominal distension of short duration, clinically diagnosed as ascites, was subsequently proved to be giant omental cyst. The case is reported because of its unique presentation.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
10/141. Persistent interstitial pulmonary emphysema-like cyst associated with metastatic synovial sarcoma.Interstitial pulmonary emphysema is characterized by the presence of gas dissecting the interstitial tissues of the lung. Clinically, it may be acute or persistent, and the latter can be further categorized as localized or diffuse. Usually, it appears in preterm neonates with a history of assisted ventilation or respiratory distress. Although far from frequent, the localized variety of persistent interstitial pulmonary emphysema (PIPE) can develop spontaneously in full-term babies or infants without any obvious underlying pulmonary disease. Histologically, PIPE is characterized by the presence of uni- and multinucleated histiocytes lining the inner surface of the cysts. In this report, we describe a 15-year-old male with synovial sarcoma (SS) of the right ankle diagnosed 4 years previously who developed pulmonary metastasis, one of which presented cystic changes with features of PIPE.- - - - - - - - - - ranking = 0.42233987282614keywords = multinucleated (Clic here for more details about this article) |
