Adrenal myelolipoma associated with adenoma
2004
The association of an adrenal myelolipoma with a non-functioning adenoma is very rare. Herein, we report on such a case in an asymptomatic 64-year-old woman. To the best of our knowledge, there is only one other case of non-functioning adrenocortical adenoma associated with myelolipoma in the same gland. Furthermore, only two other adenomas (mineral corticoids and corticosteroid producing tumors) associated with myelolipomas have been reported, and both myelolipomas were less than 1 cm in size. In conclusion, the 8.5 cm myelolipoma in our case is the largest compared with the three previously reported ones.
Zur Frage des pl�tzlichen Todes beim sogenannten Myelolipom der Nebennieren
1967
Es wird uber ein doppelseitiges sog. Myelolipom der Nebennieren bei einer 54jahrigen Frau berichtet, das wahrscheinlich uber ein allgemeines Schocksyndrom zum plotzlichen Tode fuhrte.
Presacral Myelolipoma
2014
Many reports have described adrenal myelolipomas but there have been only a few reports of extra-adrenal myelolipomas. We describe a 74-year-old woman who came to our observation for MRI of the lumbar spine for typical lumbar back pain. In addition to signs of mild scoliosis and spondylo disc arthrosis, MR imaging revealed a presacral mass showing a heterogeneously high signal in all pulse sequences and almost completely suppressed on inversion recovery sequences for fat tissue. CT imaging confirmed the fatty nature of the lesion and no signs of bone involvement. These findings were most consistent with a diagnosis of a rare presacral myelolipoma as confirmed at histopathologic analysis. T…
Ocean acidification impairs vermetid reef recruitment
2014
Vermetids form reefs in sub-tropical and warm-temperate waters that protect coasts from erosion, regulate sediment transport and accumulation, serve as carbon sinks and provide habitat for other species. The gastropods that form these reefs brood encapsulated larvae; they are threatened by rapid environmental changes since their ability to disperse is very limited. We used transplant experiments along a natural CO2 gradient to assess ocean acidification effects on the reef-building gastropod Dendropoma petraeum. We found that although D. petraeum were able to reproduce and brood at elevated levels of CO2, recruitment success was adversely affected. Long-term exposure to acidified conditions…
Management of Toxicity Induced by Anti-EGFR Therapy in Metastatic Colorectal Cancer
2013
Use of anti-epidermal growth factor receptor (anti-EGFR) agents has yielded significant advances in the treatment of patients with metastatic colorectal cancer. In fact these drugs, which include the monoclonal antibodies cetuximab and panitumumab, can be delivered both as a single agent and in combination with chemotherapy, achieving better survival and quality of life and in some cases also resectability of metastases. However, these agents can result in the development of toxicities that are usually different from those observed with chemotherapy alone. For the management of these adverse effects, proper knowledge is mandatory. Skin toxicity is the most frequent adverse effect. Other tox…
Gigantic tongue lipoma : a case report
2006
Lipomas are among the most common tumors of the human body. However, they are uncommon in the oral cavity. In the oral cavity they present as a slow growing, painless, and assymptomatic yellowish submucosal mass. Surgical excision is the treatment of choice with recurrence not expected. They have been known to grow to large sizes causing mastication and speech difficulties. The usual lesions consist of a well circumscribed, lobulated mass of mature fat cells. In other situations the covering mucosa becomes ulcerated and presents difficulties in diagnosis. The present report is of a patient who presented with a gigantic lipoma on the tip of the tongue which had been present for 3 years. She …

No. of bitstreams: 0 Previous issue date: 2010-03-01 Lipomas are benign mesenchymal neoplasms of soft tissue that can be found in any part of the human body. Conversely, their presence in the oral mucosa is rather uncommon, with approximately 4% of the cases occurring in the oral cavity. In such cases, th…
Intraoral lipomas: A clinicopathological study of 43 cases, including four cases of spindle cell/pleomorphic subtype
2018
Background The aim of this study was to describe the clinicopathological characteristics of 43 intraoral lipomas and classify them according to their microscopic variants. Material and Methods All the cases of intraoral lipomas diagnosed at an Oral Pathology service were selected for the study. Clinical data, such as age, gender, location, time of evolution, clinical presentation, clinical hypothesis of diagnosis, and treatment, were collected from the clinical files. Results Of the 43 cases analyzed, 24 (55.8%) occurred in women. The mean age was 77.4 years. The most affected site was the buccal mucosa (22 cases, 51.1%). The mean lesion size was 1.7 cm. Twenty-three cases (53.5%) were clas…
Large intraoral spindle cell lipoma
2021
Lipomas are relatively common benign neoplasms composed by mature fat cells. Apart from conventional lipomas, several other subtypes have been described in the oral cavity, including fibrolipoma, myxoid lipoma, angiolipoma, myolipoma, chondrolipoma, osteolipoma and spindle cell lipoma (SCL). Intraoral SCL is rare, representing from 1.4% to 9.8% of all intraoral lipomas. The aim of the present study is to report a case of a large intraoral SCL of the buccal mucosa affecting a 46-year-old male, calling attention to its clinical and histological features and to its successfull surgical conservative management. Key words:Lipoma, spindle cell, oral, buccal mucosa.
Nonepithelial skin tumors with multinucleated giant cells
2013
Recognition of the different types of multinucleated giant cells in neoplastic and pseudotumoral lesions of the skin may be helpful in the differential diagnosis of these tumors. In this review, we will analyze the different types of multinucleated giant cells that can be found in nonepithelial cutaneous tumors and, more importantly, the clinicopathological context in which they are found. Touton giant cells are typically present in juvenile xanthogranuloma, necrobiotic xanthogranuloma, and some subtypes of xanthomas. Giant cells with a ground glass appearance are typically present in the solitary reticulohistiocytoma and multicentric reticulohistiocytosis. Osteoclast-like cells are found i…
