1/96. teratoma in the region of adrenal gland: a unique entity masquerading as lipomatous adrenal tumor.BACKGROUND: The aim of this study was to establish the clinical and pathologic aspects of 3 atypical lipomatous lesions in the region of the adrenal gland. methods: Three young Chinese patients (ages 18, 18, and 37 years) were seen for nonspecific back pain. Radiologic examination revealed a lipomatous lesion in the region of the adrenal gland, and hormonal assessment was normal. Calcification was noted in 2 of the 3 lesions. adrenalectomy was performed because of the size (diameter 7.5, 10, 11 cm) of the tumors with suspected local symptoms. RESULTS: On gross examination 2 tumors were cystic and 1 was solid. In all 3 patients the diagnosis was mature teratomas. The tumors were composed of mature tissues arising from more than 1 germinal layer. There was no evidence of immature elements or malignancy. adipose tissue was the predominant component in the tumors. There was no evidence of recurrent diseases in all these patients during follow-up. CONCLUSIONS: To our knowledge, this is the first report of teratomas occurring in the adrenal region. teratoma should clinically and radiologically be included in the differential diagnoses of lipomatous adrenal lesions. Excision of the teratoma is advocated.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
2/96. Lipoma of the adrenal gland.A rare case of a lipoma of the adrenal gland is reported with a review of the literature. The tumor was incidentally found at autopsy in a 50-year-old man who died from severe head trauma after a traffic injury. At autopsy, an oval-shaped, soft yellow nodule measuring 1.1 cm in diameter was found in the right adrenal cortex. Histological examination revealed a lesion consisting of mature adipose tissue partially surrounded by a thin fibrous capsule. On serial sections there was no evidence of hematopoiesis nor of adrenal medulla cells. To the best of our knowledge, this is the eighth case described in the English literature. With the increasing use and the high resolution of modern imaging techniques, these unsuspected adrenal masses may become more prevalent.- - - - - - - - - - ranking = 0.83333333333333keywords = gland (Clic here for more details about this article) |
3/96. Benign symptomatic thymic tumors.Benign tumors of the thymic gland are relatively rare. Although most of these lesions are asymptomatic in nature, they may result in respiratory distress. This report describes 2 cases of benign thymic tumors presenting with respiratory symptoms that resolved after operative excision.- - - - - - - - - - ranking = 0.16666666666667keywords = gland (Clic here for more details about this article) |
4/96. lipomatosis of the parotid gland in a child.lipomatosis of the parotid gland is a very rare tumour and its discovery in a child is exceptional. These tumours are not generally considered in the preoperative differential diagnosis of parotid region neoplasms because of their rarity. The treatment of choice is surgical excision, with a superficial or total parotidectomy, preserving the facial nerve. Long-term follow-up is advised due to possible microscopic infiltration. A case of lipomatosis of the parotid gland in a 4-month-old child is reported.- - - - - - - - - - ranking = 1keywords = gland (Clic here for more details about this article) |
5/96. Sialolipoma: a report of seven cases of a new variant of salivary gland lipoma.AIMS: We propose the designation 'sialolipoma' to establish and characterize a new category of benign lipomatous tumour occurring in salivary glands. Until now, these tumours have not been regarded as a distinct entity in the salivary glands. methods and RESULTS: We evaluated the clinicopathological and immunohistochemical features of seven sialolipomas among 2051 surgically resected primary salivary gland tumours deposited in our files. The seven patients with sialolipoma were five men and two women, aged 20-75 years (mean: 54.4 years). Five tumours had arisen in the parotid gland, one in the soft palate, and one in the hard palate. The tumours ranged from 10 to 60 mm (mean: 38 mm) in maximum diameter. Histologically, the tumours were characterized by a well circumscribed mass composed of glandular tissue and mature adipose elements. The adipose elements in the tumours arising in the parotid gland were more abundant than those arising in the minor salivary gland. The glandular components consisted of ductal, acinar, basal and myoepithelial cells, and closely resembled the cellular and structural compositions of normal salivary gland tissues. These findings were confirmed by immunohistochemical and ultrastructural studies. These components had no atypia, except for the presence of some minor variations, e.g. ductal ectasia with fibrosis and focal oncocytic metaplasia. In all cases, cell proliferative activity, as assessed by Ki67 (MIB1) immunostaining, was low. From these findings, it is likely that our cases were lipomas with secondary entrapment of the salivary gland elements. No recurrence was seen in all cases after superficial parotidectomy, or after surgical excision in the patients with palatal tumours. CONCLUSIONS: We regard sialolipoma as a distinct variant of salivary gland lipoma that can occur in both the major and minor salivary glands. Superficial parotidectomy, or surgical resection in the case of palatal tumours, is an appropriate treatment for this benign tumour.- - - - - - - - - - ranking = 2.6666666666667keywords = gland (Clic here for more details about this article) |
6/96. Spindle cell lipoma of the parotid: fine-needle aspiration and histologic findings.A 47-year-old man presented to the otolaryngologist with a 7-year history of a mass of the cheek. Fine-needle aspiration revealed foci of spindled cells admixed with abundant fat and myxoid material. A diagnosis of spindle cell lipoma was rendered on the resected specimen. The cytologic findings of spindle cell lipoma of the parotid gland as seen by fine-needle aspiration are presented along with the histologic correlates.- - - - - - - - - - ranking = 0.16666666666667keywords = gland (Clic here for more details about this article) |
7/96. Lipoma in the deep lobe of the parotid gland: a case report.We report here on a rare case of lipoma in the deep lobe of the parotid gland. MRI revealed that the tumour was situated mainly in the deep lobe and it extended posteriorly and medially into the space between the sternocleidomastoid muscle and the posterior belly of the digastric muscle, with slight extension into the parapharyngeal space. This tumour produced strong signals on T1- and T2-weighted MR images and weak signals on fat suppression images. In addition, MRI clearly showed the margin of the tumour, which enabled us to readily distinguish the tumour from the surrounding adipose tissue. The images suggested a diagnosis of deep lobe parotid lipoma with posteromedial extension to the sternocleidomastoid muscle, which proved true at surgery. We thus believe that MRI is highly useful, perhaps even necessary, in diagnosing tumours of the head and neck.- - - - - - - - - - ranking = 0.83333333333333keywords = gland (Clic here for more details about this article) |
8/96. Radiologic and cytologic findings in a case of thyrolipoma.Thyrolipomas are rare capsulated mass lesions containing fat and thyroid tissue. We herein report the case of a 60-year-old man who had goitre for 10 years, with rapid enlargement of the gland during the last several months before presentation. Sonography, scintigraphy, CT, MR imaging, and sonography-guided fine needle aspiration were performed. Sonography and scintigraphy revealed an unusual mass of the thyroid. The diagnosis of thyrolipoma was based on CT and MR imaging findings and fine needle aspiration cytology.- - - - - - - - - - ranking = 0.16666666666667keywords = gland (Clic here for more details about this article) |
9/96. Lipoadenoma: is it arising from thyroid or parathyroid? A diagnostic dilemma.Fat-containing lesions of endocrine organs are rare. Distinguishing lipoadenomas of the thyroid gland from lipoadenomas of parathyroid glands can be challenging during intraoperative consultation. Our patient had a well-circumscribed tan-pink nodule present on the surface of the thyroid gland, exhibiting abundant fat interspersed between the cells, with ample eosinophilic cytoplasm arranged in trabeculae and solid sheets. immunohistochemistry showed strong positivity for thyroglobulin confirming the origin of the nodule to be thyroid. Only few cases of lipoadenomas of the thyroid and parathyroid have been reported in the literature. There is considerable histologic overlap between the two, making it difficult to determine the site of origin. We briefly discuss the features that may be helpful in this distinction.- - - - - - - - - - ranking = 0.5keywords = gland (Clic here for more details about this article) |
10/96. central serous chorioretinopathy associated with adrenal myelolipoma.BACKGROUND: We describe a case of central serous chorioretinopathy associated with a large adrenal myelolipoma. history AND SIGNS: A 55-year old man was admitted to our clinic complaining for metamorphopsia and blurred vision in his left eye. Standard ophthalmologic examination and fluorescein angiography established the diagnosis of central serous chorioretinopathy (CSC). Due to the presence of arterial hypertension, we proceeded to a thorough systemic clinical and laboratory investigation. THERAPY AND OUTCOME: Clinical and laboratory investigation disclosed a large mass in the right abdominal region. magnetic resonance imaging showed that this mass was located superior to the right kidney, in the right adrenal gland, compressing the kidney and the liver. Surgical excision of the mass was done one month later. Histological examination revealed an adrenal myelolipoma. Improvement of CSC was recorded one month after surgery with complete remission two months later. Additionally, systemic blood pressure and increased urinary steroids concentration before the operation returned to normal in the late postoperative period. CONCLUSIONS: CSC pathogenesis is not well understood. Many factors are implicated in this disease. Hypercortisolism and sympathetic activity play a crucial role in the pathogenesis of CSC. This is the first report of CSC in a patient with a benign tumor of the adrenal gland without Cushing's syndrome.- - - - - - - - - - ranking = 0.33333333333333keywords = gland (Clic here for more details about this article) |
