1/10. Intrapericardial bronchogenic cysts.A rare case of large intrapericardial bronchogenic cyst with superior vena caval obstruction is reported. The cyst was successfully removed and the superior vena cava, which was narrowed by pressure fibrosis and thrombosis, was reconstructed satisfactorily and has maintained patency. In another case a large cyst of the same type without vena caval obstruction was successfully treated surgically. The features of these 2 cases are compared with those of 20 reported cases. The angiographic data in these cases appear to be sufficiently characteristic to suggest the nature of the lesion and the clinical finding of pericarditis early in the course of the disease may also suggest the diagnosis.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/10. Congenital cervical teratoma--an unusual presentation.We report a case of congenital benign cervical teratoma in a female child. The unusual asymptomatic nature of the tumour and its relationship with the thyroid is highlighted.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/10. Thyroid anaplastic carcinoma transformed from papillary carcinoma in extrathyroid area.We report a 75-year-old male with anaplastic carcinoma in an extrathyroid area. Thyroid remained unchanged. The patient is alive without incident of tumor recurrence at 3.5 years after total resection and at 5 years after initial symptom. The tumor developed between the sternocleidomastoid muscle and common carotid artery, and was completely separated from the thyroid. The tumor location was consistent with a branchial cyst. The tumor consisted of two parts; an upper solid tumor and a deep cystic tumor. The former showed anaplastic carcinoma with osteoclast-like giant cells. The latter was consistent with thyroid papillary carcinoma. The center was intermingled with these two carcinomas. Anaplastic carcinoma cells were positive for vimentin and papillary carcinoma cells were positive for keratin, thyroglobulin, and thyroid transcription factor-1. These results remain insufficient to find any conclusions concerning the tumor nature; either ectopic thyroid carcinoma arising from a branchial cyst or occult thyroid carcinoma metastasis. This is rare case in which thyroid anaplastic carcinoma transformed from papillary carcinoma in an extrathyroid area.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/10. Angiographic features of lateral cervical masses.An audible bruit may represent a clue to the vascular nature of the lesion. angiography is definitely indicated in the presence of pulsatile cervical masses with or without an associated bruit, and should be more widely utilized in the future for evaluation of cervical masses. In addition to the nature of the mass, angiography may also be of value in outlining the extent of the mass and its relationship to major vessels. Magnification and subtraction angiographic techniques with their improved detail may play an important role in clarifying the etiology of cervical masses, and hence facilitate the plan of therapy. If reasonable uncertainty as to the clinical diagnosis exists, angiography should be considered a diagnostic aid.- - - - - - - - - - ranking = 2keywords = nature (Clic here for more details about this article) |
5/10. Branchial cleft cyst to jugular vein fistula. An unusual complication.Although fistulization between branchial cleft cysts and major vascular structures is extremely rare, it is a potentially serious complication, particularly with recurrent episodes of inflammation. Needle aspiration of a fluctuant lesion prior to formal incision and drainage is crucial. It confirms the nature of the lesion, thus avoiding potential complications. The importance of early exploration and excision of this type of fistula makes possible the early definitive treatment of branchial cleft cysts.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/10. First branchial cleft cysts presenting as parotid tumors.Masses of the parotid gland region can be caused by a variety of different conditions, most commonly neoplasms of a benign or malignant nature. A rare cause for parotid tumors is the embryonologic remnant of first branchial cleft cysts. We reviewed branchial cysts for a 10-year period at the three teaching hospitals in Akron, OH. First branchial cleft cysts, or parotid lympho-epithelial cysts, were found to be a very rare condition presenting as parotid tumors. The surgeon should always be aware of these cysts as a possibility in the differential diagnosis of parotid masses in the infant and adult.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
7/10. Malignant branchioma--a further insight.Two cases presented with solitary cystic mass in the usual position of a branchial cyst in the neck are reported. histology on both cysts reported as carcinoma of a branchial cyst (malignant branchioma). In addition to pre-operative radiotherapy to the neck, and ipsi-lateral radical neck dissection, the oropharynx is irradiated in prophylactic manner only in the second case. The first patient died of tonsillar carcinoma 3.5 years after diagnosis and the second case is well with no sign of recurrence 4 years after the initial diagnosis. The authors discuss the nature and management of the so called malignant branchioma.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
8/10. Pharyngeal dermoids ("hairy polyps") as accessory auricles.The purpose of this study is to clarify the origin and nature of so-called hairy polyps or dermoids of the pharynx, which are often thought to be a variant of pharyngeal teratoma. For this purpose, a case is reported of a dermoid polyp involving the middle ear of an infant, the features of multiple examples of pharyngeal dermoid polyps and teratomas received for consultation by the Armed Forces Institute of pathology are examined, and selected pertinent reports from the literature are reviewed. All three means are used to support the conclusion that these lesions are choristomatous developmental anomalies arising from the first branchial cleft area and that they essentially represent heterotopic accessory "ears" (auricles) without the growth potential of a teratoma.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
9/10. facial paralysis caused by a lymphoepithelial cyst located in the parotid gland.We report the case of an acute onset facial paralysis which was caused by a benign lymphoepithelial cyst found in the parotid, an association which is a rarity in the literature. The diagnosis and surgical management is discussed. This report emphasises the clinical principle that parotid masses causing an acute facial palsy are not necessarily malignant in nature. Intra-operative frozen section histology is helpful in saving the patient from unnecessarily radical surgery.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
10/10. Endoscopic cauterization for treatment of fourth branchial cleft sinuses.Fourth branchial cleft sinuses are rare, and the nature of their origin is controversial. Clinical presentation is varied because they may present as asymptomatic neck masses, recurrent neck abscesses, or suppurative thyroiditis. We describe herein 7 children who presented with abscesses on the left side of their necks, 3 of whom had abscesses that involved the thyroid gland. Direct laryngoscopy revealed that all 7 children had a sinus tract opening into the apex of the piriform sinus. Endoscopic obliteration of this tract was achieved using an insulated electrocautery probe either when the abscess was initially incised and drained or 4 to 6 weeks later. All 7 children recovered uneventfully. Four of the 7 children were followed up for more than 18 months without recurrence.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
