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 observa- tion 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. …
Management of Renal Angiomyolipoma: A Report of 14 Cases and Review of the Literature
1994
14 patients with renal angiomyolipoma are presented. Two of them had tuberous sclerosis (TS) with synchronous bilateral and multiple tumors. Two other patients without TS also had multiple tumors in 1 kidney. More than half the patients were symptomatic (n = 8), 2 of them with spontaneous rupture of the tumor. Misdiagnosis, spontaneous rupture and tumor growth can be prevented by utilizing conservative, organ-sparing techniques. In cases of solitary kidneys with large and/or hemorrhagic angiomyolipoma, superselective arterial embolization is indicated.
SEVERE STREPTOCOCCUS PYOGENES SURGICAL SITE INFECTION AFTER INGUINAL LIPOMA REMOVAL
2019
Surgical site infections (SSI) are a common cause of health care-associated infections. They are localized in the surgical incision site and can lead to deep tissues spreading. Among the wide spectrum of SSIs , we will consider specifically group A streptococcus cellulitis. This kind of infection can have a negative evolution and result in necrotizing fasciitis (NF), previously known as streptococcal gangrene. The term NF indicates a rare necrotizing infection involving any of the soft tissue layers that still have a high mortality rate from 7% to 76%. An early diagnosis and urgent treatment are key to ensuring the safety of the patients’ life. A 64-year-old man underwent a complete surgica…
Lipome du lobe profond de la glande parotide : à propos d'un cas rarissime
2006
The incidence of lipoma in the parotid gland is very low, and lipomas in the deep lobe of the parotid are extremely rare and seldom considered in the differential diagnosis of deep lobe parotid gland tumours. A deep lobe parotid gland lipoma is presented and discussed.
Sporadic oral angiomyolipoma: Case report
2007
Angiomyolipoma (AML) is a rare, benign tumour composed of a variable proportion of lipocytes, smooth muscle and thick-walled blood vessels. AML is part of a family of tumours arising from perivascular epithelioid cells (PEComas), and many cases are associated with tuberous sclerosis, with the kidney being the most frequent site involved. We report a case of sporadic AML in the hard palate of a 52-year-old male, an extremely unusual location for this tumour. Differentiation from other benign and malignant oral mesenchymal lesions depends on recognition of the three histologic components, and immunohistochemical techniques may be helpful. AML occurring in the head and neck do not express HMB-…
Angiomyolipoma of the upper lip : case report and review of the literature
2007
Angiomyolipoma (AML) is a hamartomatous growth that usually affects the kidney. One third of patients with AML present with manifestations of tuberous sclerosis. Oral AML is rare with only 6 cases reported in the English-language literature. In the present case, AML was located in the upper lip of a 43 year-old woman. Clinically, it presented as a firm nodule, well circumscribed and measuring 1x2 cm. It was surgically excised. Histopathological analysis showed a lesion composed of an admixture of smooth muscle cells, blood vessels, and adipose tissue. The immunohistochemical study revealed positivity for vimentin, smooth muscle actin, pan specific muscle actin and desmin. CD68, CD34 and mas…
Spindle cell lipoma of the floor of the mouth. A case report.
2006
A sessile swelling in the floor of the mouth appeared three years ago in a 29-year old Caucasian female located laterally to the opening of the right duct of Wharton. The mass covered by normal looking mucosa exhibited slight growth since then. After excision, histological examination revealed the presence of a tumor formed by areas of mature adipose cells interspersed with extensions of tightly disposed fusiform fibroblasts immunoreactive for vimentin and CD-34. There were foci of concentric fibroblasts forming dense whorls. When large these conglomerates exhibited chondrocytes in the center. Mast-cells were not rare throughout the fibroblastic areas. No signs of malignancy occurred. These…
LIPOCORISTOMA DELL’ANGOLO PONTO-CEREBELLARE: UN NUOVO NOME PER UNA VECCHIA CONOSCENZA
2019
SCOPO DEL LAVORO: I lipochoristomi sono rari tumori benigni (0.1% di tutti i processi espansivi dell’angolo ponto-cerebellare) che in passato si riteneva derivassero dalle cellule della primitiva meninge e pertanto venivano definiti come lipomi dell’angolo ponto-cerebellare (o del condotto uditivo interno). Oggigiorno sono più propriamente definiti come "coristomi lipomatosi" (o lipocoristomi) poiché si è dimostrato che originano dal tessuto mesenchimale proprio del nervo vestibolo-cocleare. Scopo del presente lavoro è quello di presentare dei casi di lipocoristoma alla luce dei dati oggi riportati nella più recente letteratura. MATERIALI E METODI: Saranno presentati casi di pazienti con ri…
Endoscopic Resection of a Large Colonic Lipoma: Case Report and Review of Literature
2010
Colonic lipomas are uncommon, benign, submucosal adipose tumors that are usually asymptomatic. Large lipomas can cause symptoms such as constipation, abdominal pain, rectal bleeding and intussusception. We report the case of a 60-year-old man with a history of lower abdominal pain and pseudoobstructive symptoms. Colonoscopy revealed a large polypoid sessile lesion in the sigma. We used a standardized technique of polypectomy, preceded by submucosal injection of dilute 5 ml polygelin with epinephrine 1:10,000 solution, to fully resect large colonic lipomas. The lipoma size was 3.5 cm. No bleeding or perforation developed. Histology showed the polyp to be a submucosul lipoma. On follow-up, th…
Tumors of the labial mucosa: a retrospective study of 1045 biopsies
2020
Background To investigate the relative frequency of localized mucosal swellings of the upper and lower labial mucosa, the clinical-pathological diagnosis agreement and whether patient’s age and gender and tumor’s site and size may raise the suspicion of neoplasm. Material and Methods Retrospective analysis was performed on upper or lower labial mucosal tumors, histopathologically diagnosed between 2009-2018. The diagnostic categories developmental/reactive tumors, benign and malignant neoplasms were associated with patient’s age and gender and tumor’s site and size; clinical-pathological diagnosis agreement was, also, evaluated. Results Overall, 1000 (95.7%) developmental/reactive tumors, 3…
