11/141. Ectopic adrenals in a sirenomelic fetus.A sirenomelic malformation was diagnosed in a fetus from the first pregnancy of a 25-year-old woman, and it was aborted at the 24th week of gestation. The fetus represented a sympus monopus. The head, organs of the neck, the thorax, and the upper part of abdominal cavity were normally formed. The kidneys, the ureters, the urinary bladder and the urethra were not developed. Adrenals of discoid shape and normal size were present in the normal position. The large bowel ended blindly in the sigmoid colon. Both testes were found in their normal position in the pelvis. Two symmetrical structures, resembling ovaries in shape and colour, were found near the testes. Histological examination established that these two organs were accessory (aberrant) adrenals.- - - - - - - - - - ranking = 1keywords = accessory, organ (Clic here for more details about this article) |

13/141. Epidermoid cyst of an intrapancreatic accessory spleen--a case report.We report an extremely rare case of a splenic epidermoid cyst of the pancreas in a 51-year-old Japanese male with no clinical symptoms. A cystic tumor of the pancreatic tail was detected incidentally by abdominal ultrasonography. The patient was referred to the Gunma University Hospital for further examination of the pancreatic tumor. Upon diagnosis of a benign cystic tumor, a distal pancreatectomy with splenectomy was performed. Microscopically, the multicystic tumor, which was surrounded by the splenic tissue, was located within the pancreatic tissue. The cysts were lined by non-keratinizing squamous epithelium. The diagnosis of an epidermoid cyst occurring in an intrapancreatic accessory spleen was confirmed. To our knowledge, this is the 4th case ever reported in the English literature.- - - - - - - - - - ranking = 4.9970641071919keywords = accessory (Clic here for more details about this article) |
14/141. Misplaced parotid glands: bilateral agenesis of parotid glands associated with bilateral accessory parotid tissue.Agenesis of the parotid is a rare entity. It is usually unilateral but bilateral cases have been described as a rare cause of xerostomia. Accessory parotid tissue is also uncommon and is not normally associated with aplasia of the parotid gland. The embryological, histological, clinical and radiological findings of these two entities will be discussed in addition to the report of an obscure case of bilateral parotid agenesis together with bilateral accessory parotid tissue.- - - - - - - - - - ranking = 4.9970641071919keywords = accessory (Clic here for more details about this article) |
15/141. Epithelial inclusion cyst (epidermoid cyst) formation with epithelioid cell granuloma in an intrapancreatic accessory spleen.The histologic characteristics of a case of epidermoid cyst formation with an epithelioid cell granuloma that developed in intrapancreatic accessory spleen were investigated, with the aim of clarifying its origin as well as etiologic factors. The patient, a 48-year-old male, was found to have a cystic lesion in the tail of the pancreas and renal cell carcinoma (clear cell carcinoma) during a medical check up. The pancreatic mass appeared to be a so-called "mucinous tumor" on imaging, and combined resection of the body and tail of the pancreas and the spleen was performed together with a left nephrectomy. The lesion in the tail of the pancreas was then demonstrated to have accessory splenic tissue with cyst formation in its central region. The cystic wall was covered with stratified squamous epithelium and ductal epithelium with squamous metaplasia, and pancreatic islet cells were evident at various sites within the accessory spleen. Formation of epithelioid cell granuloma tissue was observed around the cysts. The epithelium of the cyst was positive for CA19-9 and negative for antibodies against mesothelial cells, whereas the pancreatic island cells were positive for insulin. These results suggested that cystic epithelium in the accessory spleen could be derived from pancreatic duct epithelium. Frequent recurrence of chronic inflammation and epitheloid cell granuloma formation may have resulted from an aberration of the ectopic remaining pancreatic tissue in the spleen.- - - - - - - - - - ranking = 7.995302571507keywords = accessory (Clic here for more details about this article) |
16/141. Ectopic prostate: case report of a presacral mass presenting with obstructive symptoms.We report the unusual case of a 78-year-old man who presented with obstructive bowel symptoms and a 2.5-cm presacral mass. The mass was excised and found on pathologic examination to be ectopic prostate tissue complete with a muscular stroma. review of the literature revealed a number of case reports describing variably sized fragments of ectopic prostate tissue involving a variety of organs, including spleen, uterine cervix, bowel wall, pericolic fat, anal submucosa, seminal vesicle, testis, and urinary bladder. However, to our knowledge, this case is unique in that it presented as a relatively large, isolated presacral mass causing functional bowel impairment. The ectopic location can be related to the normal embryonic development of the prostate, rectum, and bladder.- - - - - - - - - - ranking = 0.00029358928081448keywords = organ (Clic here for more details about this article) |
17/141. Accessory spleen torsion: US, CT and MR findings.Torsion of an accessory spleen is a very unusual entity that can appear with abdominal pain associated with the presence of an avascular mass. We report the case of a 13-year-old boy with torsion and infarction of an accessory spleen presenting as a painful abdominal mass in which imaging examination with US, CT and MR showed a large avascular mass in the upper left abdomen.- - - - - - - - - - ranking = 1.9988256428767keywords = accessory (Clic here for more details about this article) |
18/141. Identification and management of intravagal parathyroid adenoma.Intravagal parathyroid adenomas are rare, with only three cases reported in the English literature. The objective of this report is to describe two additional patients with hyperfunctioning parathyroid glands found within the vagus nerve and to define the anatomy of this finding. Both patients presented with a history of persistent hyperparathyroidism despite multiple therapeutic interventions. A high cervical localization was established in both cases by selective venous sampling. In each patient successful removal of the intravagal parathyroid gland was achieved with subsequent resolution of calcium and parathyroid levels. Each adenoma was located within the vagus nerve below the level of the carotid bifurcation and was enucleated without sacrificing the vagus nerve. In our cases and those reported previously, the parathyroid glands were supernumerary, representing parathyroid tissue embryologically derived from the third branchial pouch. Exploration for hyperparathyroidism requires a complete, meticulous surgical dissection to identify all parathyroid glands and to search for possible accessory tissue in selected cases. Our experience and a review of the literature serve to emphasize that, although rare, intravagal parathyroid adenomas do occur. Examination of the vagus nerve should therefore be strongly considered when four normal glands are found, as intravagal adenomas appear to represent accessory ectopically located parathyroid tissue.- - - - - - - - - - ranking = 1.9988256428767keywords = accessory (Clic here for more details about this article) |
19/141. breast cancer in ectopic breast tissue.Ectopic breasts usually develop along the mammary ridges. Their incidence has been reported as up to 5-6%. Development of malignancy is rare. We report three cases of postmenopausal female patients with breast cancer which developed in the axillary accessory breast. They were all successfully treated by surgery and adjuvant therapy. A review of the literature on the incidence and pathology of ectopic mammary tissue is also presented.- - - - - - - - - - ranking = 0.99941282143837keywords = accessory (Clic here for more details about this article) |
20/141. Heterotopy of thyroid tissue--a modified therapeutical approach.OBJECTIVES: The authors describe the classification of heterotopic thyroid tissue. A survey of more than 600 literature cases is provided. Different therapy approaches for these anomalies are discussed. Data from seven subsequent cases have been added to the existing literature data. The authors present an alternative approach to the therapy of heterotopic thyroid tissue. MATERIALS AND methods: The records of seven patients treated for a heterotopy of the thyroid tissue as the Department of ENT and head and neck Surgery of First Medical school of the Charles University of Prague since 1.1.1991 to 1.1.2001 have been analyzed. RESULTS: The first group: No surgery. This approach was used for children. In these patients the heterotopic thyroid tissue is the only thyroid tissue they have, but its function is not damaged and there are no mechanical symptoms (no airway obstruction and dysphagia). TSH substitution-suppression therapy is necessary for this group. Cooperation and follow up by the endocrinology, otolaryngology and pediatric departments is necessary. At a later age these patients can be treated as in the second group. The second group: Surgery. All patients in this group had heterotopic thyroid tissue. The total removal of thyroid tissue has been preferred. Carcinomatous change or the development of mechanical syndrome, dysphagia or airway obstruction is possible. Total removal is the best surgical approach. Various surgical methods are described in the literature (CO2 laser, intraoral, mandibulotomy, middle hyotomy etc.). These patients are treated as after total thyroidectomy and substitution therapy with synthetic thyroid hormones is necessary. The authors describe and add seven cases to the literature data. The authors describe radical removal of aberrant and accessory tissue [corrected].- - - - - - - - - - ranking = 0.99941282143837keywords = accessory (Clic here for more details about this article) |
