1/6. MR imaging of a case of adenomatoid tumor of the adrenal gland.The aim of this case report is to describe the appearance on magnetic resonance imaging (MRI) of an incidentally found adenomatoid tumor of the adrenal gland, and to evaluate the utility of MRI in characterizing this type of tumor. The appearance of the tumor was nonspecific on T1-weighted in-phase, opposed-phase, and T2-weighted images, as well as its behavior after paramagnetic contrast administration, outlining the differential diagnosis among carcinoma, metastatic tumors, and pheochromocytoma. After surgery, the pathologic diagnosis was adenomatoid benign tumor of mesothelial origin. Although MRI enables the characterization of most benign lesions of the adrenal gland, the appearance of other lesions is nonspecific. In our case, MRI did not assist in preoperative diagnosis, guiding us towards a diagnosis of malignancy.- - - - - - - - - - ranking = 1keywords = adrenal gland, adrenal, gland (Clic here for more details about this article) |
2/6. Fine needle aspiration cytology of adenomatoid tumor. A case report.BACKGROUND: adenomatoid tumor is a benign neoplasm of the male and female genital tract. The epididymis is the most common site. CASE: A 25-year-old male presented with a swelling in the left side of the epididymis. Cytology showed monotonous cells arranged in sheets, cords and glandular patterns. The cell showed eccentric vesicular nuclei with fine chromatin and abundant, vacuolated cytoplasm. CONCLUSION: With the help of fine needle aspiration cytology, an accurate diagnosis of adenomatoid tumor is possible and can relieve anxiety and uncertainty in both the patient and physician.- - - - - - - - - - ranking = 0.0006337340726598keywords = gland (Clic here for more details about this article) |
3/6. Endometrial adenocarcinoma with coexisting adenomatoid tumor of the uterus.BACKGROUND: Uterine adenomatoid tumors may be present in up to 1% of hysterectomy specimens, and their infiltrative pattern may simulate that of adenocarcinomas. CASE: This is a report on the coexistence of a uterine adenomatoid tumor and an endometrial adenocarcinoma, both chance findings in a 41-year-old woman undergoing hysterectomy because of a preoperative diagnosis of metrorrhagia due to leiomyomas. CONCLUSION: Although uterine adenomatoid tumors are believed to be rare, they may pose a differential diagnostic problem in the pathologic staging of endometrial carcinomas, because they form gland-like lumina and infiltrate the myometrium. To our knowledge, no previous coexistence of these two tumors has been reported.- - - - - - - - - - ranking = 0.0006337340726598keywords = gland (Clic here for more details about this article) |
4/6. Adenomatoid of the adrenal gland.Adenomatoid tumors are common in the genital tract but rare in the adrenal gland. These tumors can be difficult to diagnose when present in extragenital sites. This type of adrenal tumor lacks specific radiographic features and can be confused preoperatively with more common adrenal gland tumors. We present the case of a 54-year-old man with an incidental right adrenal mass with calcified components and elevated urinary levels of homovanillic acid that was found to be an adenomatoid tumor of the adrenal gland.- - - - - - - - - - ranking = 1.1741869656709keywords = adrenal gland, adrenal, gland (Clic here for more details about this article) |
5/6. adenomatoid tumor of supra-renal gland.Adenomatoid tumors of adrenal gland are rare, asymptomatic neoplasias, with benign behavior, and usually are diagnosed incidentally. We report a case of a voluminous adenomatoid tumor of left adrenal gland in a 42-year old man who sought evaluation because of renal colic due to left nephrolithiasis. During the investigation, a tumor localized in left adrenal gland was identified by ultrasonography (14.3 x 10.5 x 19.0). The patient underwent adrenalectomy and pyelolithotomy with histopathological and immunohistochemical diagnosis of adenomatoid tumor of adrenal gland, being the largest one described in the literature to the moment. The patient does not present any signs of recurring lesion after a 3-year follow-up.- - - - - - - - - - ranking = 0.6729617524594keywords = adrenal gland, adrenal, gland (Clic here for more details about this article) |
6/6. skin adnexal neoplasm closely resembling adenomatoid tumor: a unique occurrence.We describe a primary skin neoplasm located in the left chest wall that closely resembled adenomatoid tumor of male and female genital tract. It occurred in a 52-year-old woman who had undergone a left quadrantectomy with regional lymphadenectomy for invasive ductal carcinoma of the breast 7 years previously. The tumor involved the dermis and subcutaneous tissue and measured 0.7 cm in greatest diameter. Immunohistochemical evaluation showed strong positivity for cytokeratin pool and negativity for CD31, calretinin, WT-180, and for estrogen and progesterone receptors. We are unaware of a previous description of this morphologic pattern in a primary skin tumor, which we have interpreted as of skin adnexal and specifically of eccrine sweat gland origin.- - - - - - - - - - ranking = 0.0006337340726598keywords = gland (Clic here for more details about this article) |
