1/35. Malignant large cell calcifying sertoli cell tumor of the testis (LCCSCTT). Report of a case in an elderly man and review of the literature.Malignant Large Cell Calcifying sertoli cell tumor of the testis (LCCSCTT) is a rare histological variant of sex cordstromal tumors. It usually arises in young males, sometimes is associated with endocrine abnormalities and has a benign course. It is exceptional in elderly men and the outcome is rarely fatal. We report a case of LCCSCTT in a 73 year-old man with fatal outcome. The tumor involved the right testis and several areas of the tunica albuginea were grossly invaded. serum levels of HCG, LH and testosterone were normal. Lymphoangiography performed after orchiectomy showed an involvement of the iliac and preaortic lymph nodes. X-ray of the chest showed no lung metastases. A thorough study of the light microscopic, immunohistochemical and ultrastructural appearances was performed. immunohistochemistry revealed positivity to vimentin, S-100 and NSE. Our observations confirm the previous findings concerning malignant LCCSCTT and point out the histogenesis of the tumor from sertoli cells.- - - - - - - - - - ranking = 1keywords = tunica (Clic here for more details about this article) |
2/35. Abdominal, scrotal, and thoracic calcifications owing to healed meconium peritonitis.meconium peritonitis is a form of chemical peritonitis resulting from in utero perforation of the gastrointestinal tract, with subsequent leakage of sterile meconium into the peritoneal cavity and the potential spaces connected with it. Involvement of the tunica vaginalis may be the sole presenting clinical manifestation of the gut perforation resolving spontaneously. In such instances, radiologically detectable calcifications in the abdomen, scrotum, and thorax are essential diagnostic points. In this study, a 4-month-old baby with abdominal, scrotal, and thoracic calcifications owing to healed meconium peritonitis is presented.- - - - - - - - - - ranking = 1keywords = tunica (Clic here for more details about this article) |
3/35. Severe ectopic calcification of the intestinal wall in a patient on long-term continuous ambulatory peritoneal dialysis therapy.We report autopsy findings of a 69-year-old man on long-term CAPD therapy for 13 years who showed linear peritoneal calcification. Continuous ambulatory peritoneal dialysis (CAPD) was started in 1982. He has been administered excessive amounts of vitamin d(3) derivatives (VitD) (2.0 to 2.5 microg daily) and calcium carbonate (4 g daily) for secondary hyperparathyroidism since initiation of CAPD. In May 1995, his intact parathyroid hormone (PTH) level increased over 1,000 pg/mL. Immediately after VitD was changed from pill to liquid, the dose was increased to 5 microg daily. Although the serum calcium level remained between 4.5 and 4.9 mEq/L, and serum phosphate level was 5.0 to 7.2 mg/dL, plain abdominal radiography and computed tomography showed continuous calcification along the intestinal wall in October 1995. In spite of the continuation of CAPD therapy, he remained asymptomatic until he died of congestive heart failure in January 1997. He experienced eight episodes of peritonitis during his clinical course. autopsy showed that numerous calcified plaques were present on the submucosal portion between the thickened serosa and the longitudinal layer of the muscularis externa. The remainder of the subserosa was fibrotic, and the small arteries had markedly thickened intima and severely narrowed lumina.- - - - - - - - - - ranking = 9.245235825576keywords = intima (Clic here for more details about this article) |
4/35. Scintimammographic findings of in situ ductal breast carcinoma in a double-phase study with Tc-99m(V) DMSA and Tc-99m MIBI value of Tc-99m(V) DMSA.The authors present a case of in situ ductal carcinoma of the breast (DCIS) with no associated mass in a 46-year-old woman examined with Tc-99m MIBI and Tc-99m(V) DMSA scans, which were acquired in separate sessions 10 minutes and 60 minutes after injection. Histologic analysis revealed a small (<1 cm) infiltrating ductal carcinoma located within the DCIS. mammography showed a cluster of microcalcifications on a very dense parenchymal background. Tc-99m(V) DMSA was characterized as positive for DCIS, especially in the delayed image. Tc-99m MIBI failed to identify the lesions previously noted. In conclusion, Tc-99m(V) DMSA scintimammography seems to have an advantage and could improve the detection of nonpalpable in situ breast carcinomas.- - - - - - - - - - ranking = 46.22617912788keywords = intima (Clic here for more details about this article) |
5/35. Chronic calcified aortic dissection.Two cases of chronic aortic dissection are presented. In both, plain chest roentgenograms revealed calcification in the outermost aspect of the dilated aorta. It is clear that this represented calcification of the dissection rather than of the true intima. These cases indicate that apparent aortic intimal calcification with dilatation of the aorta is not completely diagnostic of an arteriosclerotic aneurysm and that a chronic calcified aortic dissection must also be considered in the differential diagnosis.- - - - - - - - - - ranking = 18.490471651152keywords = intima (Clic here for more details about this article) |
6/35. Peyronie's disease: an unusual presentation with butterfly shaped calcified plaques.Peyronie's disease is characterized by the formation of a fibrotic plaque in the tunica albugenia of the penis. Two patients with calcified butterfly shaped plaques involving the ventrolateral aspect of the penis are described. These patients were managed by plaque excision and dermal grafting with excellent post-operative results.- - - - - - - - - - ranking = 1keywords = tunica (Clic here for more details about this article) |
7/35. meconium granulomas of the tunica vaginalis.meconium peritonitis results from perforation of the gastrointestinal tract during fetal life. Involvement of the tunica vaginalis may be the sole presenting clinical manifestation of the disease in the unusual event of the gut perforation resolving spontaneously. In such instances radiologically detectable calcification in the abdomen and scrotum is an essential diagnostic point. A case is described in which a baby had hydroceles and bilateral intrascrotal nodules but in which calcification was radiologically undetectable, presumably owing to its having undergon resolution. The typical histology of the nodules provided the diagnosis in this otherwise clinically undiagnostic case.- - - - - - - - - - ranking = 5keywords = tunica (Clic here for more details about this article) |
8/35. Idiopathic arterial calcification of infancy: prenatal and postnatal effects of therapy in an infant.In an infant with idiopathic arterial calcification of infancy, prenatal diagnosis of arterial calcification was made by ultrasonography and allowed initiation of therapy in utero. Etidronate therapy produced apparent radiographic and ultrasonographic improvement in the degree of vascular calcification but did not prevent the lethal progression of intimal vascular occlusive disease.- - - - - - - - - - ranking = 9.245235825576keywords = intima (Clic here for more details about this article) |
9/35. Idiopathic infantile arterial calcification: sonographic findings.Idiopathic infantile arterial calcification (IIAC) is a rare disease that is characterized by calcification in the media and fibroproliferative changes in the intima of larger arteries, sometimes resulting in reduced vascular elasticity and blood flow. Although the molecular-genetic basis of the disease is unknown, IIAC is presumed to be acquired by an autosomal recessive mode of inheritance and is associated with a reduction in the levels of enzymes responsible for inorganic phosphate balance, resulting in abnormal deposition of calcium into the vessels. We report the case of a female neonate in whom widespread IIAC was initially diagnosed on postnatal sonographic examination. At birth, the infant experienced cardiac failure and hypertension, and arterial pulsation was absent. Routine prenatal sonographic examinations had not revealed any abnormalities, but postnatal gray-scale and color Doppler echocardiographic and sonographic examinations revealed findings consistent with severe IIAC. The cardiac function improved with treatment, but the neonate died of progressive hepatic failure due to reduced flow in calcified and narrowed hepatic arteries. The common carotid arteries were also grossly affected, resulting in cerebral atrophy at the time of birth. Postnatal gray-scale and color Doppler echocardiographic and sonographic examinations allowed noninvasive diagnosis, assessment of severity, and monitoring of progression.- - - - - - - - - - ranking = 9.245235825576keywords = intima (Clic here for more details about this article) |
10/35. Dissecting abdominal aortic aneurysm in a young man: an uncommon presentation of abdominal pain.Aortic dissection results from an intimal tear that allows blood to penetrate the wall of the aorta. patients, typically males over the age of fifty with a history of hypertension, usually present with sudden onset of severe chest pain. An unusual presentation of a dissecting aortic aneurysm as a cause of abdominal pain in a 32-year-old male is discussed. Although a relatively uncommon cause of abdominal pain, it is important to keep this entity on the list of differential diagnoses and adequately rule it out before discharge from the emergency department.- - - - - - - - - - ranking = 9.245235825576keywords = intima (Clic here for more details about this article) |
