Angiomyolipoma of the Adrenal Gland: A Report of Two Cases and Review of the Literature.

BACKGROUND Angiomyolipoma is a benign tumor composed of blood vessels, smooth muscle cells, and adipose tissue and has been described as belonging to the group of tumors of perivascular epithelioid cell origin (PEComa), commonly found in the kidneys and strongly associated with tuberous sclerosis. Only a few cases of extra-renal angiomyolipoma have previously been reported in the literature, most commonly in the liver. Adrenal angiomyolipoma is very rare, is usually asymptomatic, and is often found incidentally, with only 14 previously reported cases identified in the literature. CASE REPORT We report two cases of adrenal angiomyolipoma that were identified by abdominal computed tomography (CT). The first case presented in a 36-year-old man and was an oval-shaped adrenal mass, measuring 5.2×4.2×3.1 cm. The second case presented in a 61-year-old woman and was a round-shaped mass measuring 8.6×9.5×8.1 cm. Both patients underwent adrenalectomy. Histopathology and immunohistochemistry confirmed the diagnosis of benign angiomyolipoma composed of adipose tissues, blood vessels, and smooth muscle cells. CONCLUSIONS We present two rare cases of adrenal angiomyolipoma. We have reviewed the literature and identified 14 other cases of adrenal angiomyolipoma, and discuss the clinical, radiological, and pathological features of this rare tumor.

Diagnosis and differential diagnosis for solitary fibrous tumor in the abdomen and pelvis by CT / 中南大学学报(医学版)

Objective:To study the CT features for solitary fibrous tumor (SFT) in the abdomen and pelvis and to improve the diagnostic accuracy.Methods:Fourteen patients with SFT were collected in our hospital from January,2011 to December,2015.Characteristic of images were analyzed and compared for 10 SFT,which located outside the abdominal organs with extragastrointestinal stromal tumors (EGIST),leiomyosarcoma,and schwannoma.Results:Necrosis and cystic formation were frequently present in SFT in the abdomen and pelvis.CE-CT showed serpentine vessels along the periphery,while pattern of enhancement was maplike inhomogeneous progressive.Comparing with the EGIST or schwannoma,the difference of CT value in non-contrast and the arterial phase were statistically significant (P＜0.05).The numbers of peritumoral circuity vessel were significantly different between SFT and EGIST (~=18.27,P＜0.008) or between SFT and schwannoma (x2=19.25,P＜0.008).Comparing with the leiomyosarcoma or schwannoma,SFT located outside the abdominal organs.We found that tumor necrosis rate was significantly different between SFT and leiomyoscarcoma (x2=8.00,P＜0.008).Conclusion:SFT in the abdomen and pelvis show certain CT characteristics.The CT value in noncontrast and at the arterial phase,tumor necrosis rate,and serpentine vessels along the periphery were pivotal in differentiating SFT from leiomyosarcoma,EGIST and schwannoma.

Research on Shanghai resident satisfaction of primary healthcare after new health reform / 中华医院管理杂志

Objective The research was to achieve Shanghai resident satisfaction of primary health service after new health reform.Methods During self-compiled questionnaire survey,the research adapted stratified random sampling to select 9 community health centers in Shanghai urban,rural and suburb areas.Results Shanghai resident satisfaction rate of new health reform was 85.2％.Satisfaction rate of basic medical security system was 85.0％.Satisfaction rate of basic medical service was 96.5％.Satisfaction rate of basic public health service was 95.1％.Age,region,job,education and income were main factors to satisfaction of primary health service.Conclusion From an overall point of view,Shanghai resident satisfaction of primary health service after new health reform was high.However,the level of basic medical security and convenience of reimbursement were not high.Medical expenses of primary health care institution had not been effectively controlled.Basic medicine could not fully meet the medication needs of primary health care institutions.
