These lesions were large, encapsulated masses with multiple cysts containing chylous fluid. Both were characterized by proliferating LAM cells that formed fascicles separated by slit-like channels. Some cysts were lined by ciliated epithelium resembling that of Fallopian tubes. Other cysts were lined either by flattened endothelial cells or by a mixture of these cells and epithelial cells. Many LAM cells gave a positive reaction with HMB-45 antibody. Most LAM cells in fascicles were reactive for o-smooth muscle actin and desmin. In 1 patient, many of the epithelial cells and some of the subjacent LAM cells were positive for estrogen and progesterone receptors. In conclusion, immunostaining with HMB-45 antibody and markers for smooth muscle cells can be helpful in the evaluation of problems in the differential diagnosis of lesions of extrapulmonary LAM, particularly those involving the genital system.<\/jats:p>","DOI":"10.1177\/106689690100900212","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T21:50:28Z","timestamp":1182462628000},"page":"155-162","source":"Crossref","is-referenced-by-count":17,"title":["Association of Lymphangioleiomyomatosis (LAM) with Endosalpingiosis in the Retroperitoneal Lymph Nodes: Report of Two Cases"],"prefix":"10.1177","volume":"9","author":[{"given":"Kazuhiro","family":"Matsui","sequence":"first","affiliation":[{"name":"Pathology Section, National Heart, Lung and Blood Institute, National Institutes of Health, Bethesda, MD"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William D.","family":"Travis","sequence":"additional","affiliation":[{"name":"Department of Pulmonary and Mediastinal Pathology, Armed Forces Institute of Pathology, Washington, DC"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Raimundo","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"Department of Pathology, Morristown Memorial Hospital, Morristown, NJ"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James A.","family":"Terzian","sequence":"additional","affiliation":[{"name":"Department of Pathology, Lourdes Hospital, Binghamton, NY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Rosai","sequence":"additional","affiliation":[{"name":"Department of Pathology, Sloan-Kettering Cancer Center, New York, NY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joel","family":"Moss","sequence":"additional","affiliation":[{"name":"Pulmonary-Critical Care Medicine Branch, National Heart, Lung and Blood Institute, National Institutes of Health, Bethesda, MD"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor J.","family":"Ferrans","sequence":"additional","affiliation":[{"name":"Pathology Section, National Heart, Lung and Blood Institute, National Institutes of Health, Bethesda, MD"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2001,4,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"crossref","first-page":"1254","DOI":"10.1056\/NEJM199011013231807","volume":"323","author":"Taylor JR","year":"1990","journal-title":"N Engl J Med"},{"key":"atypb2","first-page":"171","volume-title":"LAM and other diseases characterized by smooth muscle proliferation","author":"Travis WD","year":"1999"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1378\/chest.115.4.1041"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-199311000-00002"},{"key":"atypb5","first-page":"846","volume":"118","author":"Guinee DGJ","year":"1994","journal-title":"Diagnosis based on results of transbronchial biopsy and immunohistochemical studies and correlation with high-resolution computed tomography findings.
