1/24. Thoracolithiasis.Thoracolithiasis without any history of chest traumas or interventions is pathologically rare, with only 9 cases including our 2, reported thus far in the literature. Case 1: A 76-year-old man admitted to our hospital had an abnormal shadow in chest radiography that gradually enlarged. serum carcinoembrionic antigen was slightly elevated during follow-up. A milky white tumor 1.5 cm in diameter with many projections was found in the thoracic cavity and removed by thoracoscopy. Histopathological examination showed the tumor to consist of fibrous tissue with fatty necrosis at the core. Case 2: A 54-year-old woman admitted to our hospital had an abnormal shadow in chest screening radiography in 1998. Transbronchial biopsy showed this shadow to be lung adenocarcinoma. A small trigonal pyramid-shaped milky white nodule 5 mm in diameter was found in the thorax during lobectomy for lung cancer. Histopathological examination showed this nodule also to consist of fibrous tissue with fatty necrosis.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/24. Case of mediastinal seminoma with testicular microlithiasis.Testicular microlithiasis is a rare condition in which calcified concretions fill the lumina of the seminiferous tubules. We report the case of a 19-year-old Japanese man with mediastinal seminoma, normal testicular physical findings and bilateral testicular microlithiasis seen on ultrasonography. Testicular needle biopsy demonstrated multiple laminated calcifications within the seminiferous tubules without any signals of a viable germ cell tumor. To our knowledge, this is only the sixth reported case of extragonadal germ cell tumor with testicular microlithiasis.- - - - - - - - - - ranking = 2441.9311433709keywords = germ cell, germ (Clic here for more details about this article) |
3/24. lithiasis in a heterotopic pancreas of the stomach.A heterotopic pancreas is a relatively uncommon abnormality and usually of no clinical importance. A heterotopic pancreas is subject to various pathologic changes occurring in the pancreas, however, such as acute pancreatitis, cyst or abscess formation, pancreatic cancer, and islet cell tumor. We describe a rare case of a heterotopic pancreas presenting as a gastric submucosal mass with punctate calcifications occurring in a 43-year-old man.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
4/24. Intermittent small bowel obstruction by jejunal enteroliths in a patient with a Crohn's disease stricture.Small bowel obstruction is most frequently due to postoperative or inflammatory adhesions, intestinal neoplasms, hernias, or bezoars. Intermittent small bowel obstruction may be secondary to a Crohn's disease stricture or to chronic adhesive peritonitis. Enterolithiasis, usually associated with jejunal diverticulosis or with a meckel diverticulum, should be considered in patients who have not previously undergone abdominal surgical procedures. X-ray evidence of stones in the abdominal field, outside the common sites, i.e. gallbladder, kidney, bladder, should suggest a diagnosis of enterolithiasis. The authors report a case of multiple enteroliths in a patient with a segmental ileal stricture and ulcerations (diagnosed as Crohn's disease) causing frequent, intermittent occlusive symptoms, treated by segmental ileal resection.- - - - - - - - - - ranking = 1.1356595592786keywords = neoplasm (Clic here for more details about this article) |
5/24. Bilateral testicular microlithiasis with a unilateral testicular germ cell tumor: a case report.There is an important association between testicular microlithiasis and germ cell tumors. Ultrasound findings of 1-3 mm echogenic foci within the testicular parenchyma may be noted. Testicular microlithiasis in the general population without germ cell tumors or cryptorchidism has been estimated between 0.05 and 0.6%. However, findings of microlithiasis in concordance with germ cell tumors can be as high as 40%. We present the case report of a man with bilateral testicular microlithiasis and a unilateral germ cell tumor. Discussion of the relationship between these two conditions is also reviewed.- - - - - - - - - - ranking = 9767.7245734836keywords = germ cell, germ (Clic here for more details about this article) |
6/24. Radical prostatectomy as unique chance for huge prostatic stones.Prostatic calculi occur very often in men, but exceptionally they cause an almost total destruction of the prostatic parenchyma. Preferred treatment in order to obtain complete resolution is either transurethral resection or suprapubic simple prostatectomy. We report for the first time a radical prostatectomy as a unique chance for huge prostatic stones in a 56-years old man with severe urinary symptoms. We perform a retropubic radical prostatectomy using a nerve sparing technique. There were no intraoperative or postoperative complications. Though radical prostatectomy is an invasive approach to treat a young man affected by prostatic stones and without prostate cancer, we chose to perform it because of the impossibility to obtain complete recovery with transurethral or suprapubic simple prostatectomy.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
7/24. Meckel's stone ileus.Meckel's diverticulum is the most common congenital abnormality of the small bowel; it occurs in approximately 2% of the population. Complications of Meckel's diverticulum include hemorrhage, usually associated with heterotopic tissue within the diverticulum, intussusception, development of benign or malignant neoplasms, and inflammation. Formation of one or more enteroliths within a diverticulum is rare. An extremely rare complication is mechanical small bowel obstruction secondary to extrusion of an enterolith from a Meckel's diverticulum (Meckel's stone ileus). A case of Meckel's stone ileus is described herein, with a review of the literature of this extremely rare complication.- - - - - - - - - - ranking = 1.1356595592786keywords = neoplasm (Clic here for more details about this article) |
8/24. Surgically removed thoracolithiasis: report of two cases.Thoracolithiasis is a rare condition with only 12 cases of surgically removed nodules reported in the literature. We report 2 additional cases. Case 1: A 19-year-old male admitted with an abnormal shadow on a chest X-ray. Computed tomography (CT) revealed a nodule in the right lower lung lobe. The material extirpated by thoracoscopy was milky white, glossy, and 1.6 cm in diameter. Histopathologically, it consisted of fatty necrotic tissue covered with hyalinized fibrous tissue. Case 2: A 78-year-old female, with a past history of breast cancer, admitted with an abnormal shadow on chest X-ray. CT revealed a nodule in the left lung S(1 2) segment, of which transbronchial biopsy findings indicated primary lung adenocarcinoma. Exploratory thoracoscopy incidentally revealed some pearly material, 0.4 cm in diameter, in the thoracic cavity. They were extirpated during left upper lobectomy for lung cancer; all of them demonstrated concentric hyalinized fibrous tissue. Thoracic surgeons should consider this condition in the differential diagnosis of a peripheral pulmonary nodule.- - - - - - - - - - ranking = 2keywords = cancer (Clic here for more details about this article) |
9/24. Ultrasonographic findings of testicular microlithiasis associated with intratubular germ cell neoplasia.Testicular microlithiasis is an uncommon condition in which calcified concretions fill the lumina of seminiferous tubules. We report the case of a twenty-three-year-old white man with a metastatic germ cell tumor and normal findings on testicular physical examination, but abnormal ultrasonography of the right testis. orchiectomy revealed intratubular germ cell neoplasia with testicular microlithiasis. Multiple circular echogenic foci on ultrasound correlated with the histologic finding of testicular microlithiasis. Further studies are indicated for assessing ultrasonography as an adjunct for screening the population at risk for intratubular germ cell neoplasia.- - - - - - - - - - ranking = 8546.7590017982keywords = germ cell, germ (Clic here for more details about this article) |
10/24. Intrahepatic cholesterol stones associated with peripheral cholangiocellular carcinoma: an autopsy case.A rare autopsy case of intrahepatic cholesterol stones associated with peripheral intrahepatic cholangiocellular carcinoma is presented. The patient, a 60-yr-old man, was diagnosed as having peritoneal dissemination of adenocarcinoma, and died of respiratory failure 4 months later. At autopsy, intrahepatic cholangiocellular carcinoma was found at the left lateral segment of the liver. The cancer was extensively disseminated to the peritoneal cavity. In addition, the liver harbored a cholesterol stone (1.0 cm in diameter) impacted in the right peripheral bile duct, as well as tiny cholesterol stones (0.1-0.2 cm in diameter) scattered in the intrahepatic peripheral bile ducts. A few tiny cholesterol stones were also present in the cancerous bile ducts. Although the causal relationship between the intrahepatic cholesterol stones and cholangiocellular carcinoma remains speculative, clinicians should be aware of this association.- - - - - - - - - - ranking = 2keywords = cancer (Clic here for more details about this article) |
