OBJECTIVE
To determine whether renal angiomyolipomas from women with pulmonary lymphangioleiomyomatosis (LAM) express estrogen receptor (ER) and progesterone receptor (PR).
METHODS
Retrospective study of archival tissue.
METHODS
Twelve women with LAM and angiomyolipomas.
METHODS
Fox Chase Cancer
A 28-year-old woman with lymphangioleiomyomatosis had severe changes in the chest radiograph and recurrent pneumothoraces. Pathological tissue from the lung was progesterone receptor positive. After treatment with medroxyprogesterone her condition improved, but did not become clinically stable until
A 35-yr-old woman, with profound dyspnea at rest and failure to thrive, asked to be evaluated at Stanford Medical Center. She requested a second opinion after entering death counseling in another institution because of an unrelenting, deteriorating course caused by pulmonary lymphangiomyomatosis.
Immunohistochemical and confocal microscopic studies were made on lung tissue from 10 women with lymphangioleiomyomatosis (LAM) to evaluate the distribution of estrogen receptors (ER) and progesterone receptors (PR) in the abnormal smooth muscle cells (LAM cells) that characterize this disorder. PR
Angiomyolipoma is the most common mesenchymal renal tumour, the clonal origin of which has recently been demonstrated. It is composed of varying amounts of blood vessels, smooth muscle and fat. In this report, we describe a renal angiomyolipoma, which is unusual owing to the presence of a
Lymphangioleiomyomatosis is a rare devastating disease affecting women mostly of child-bearing age. It presents with spontaneous pneumothorax, chylous effusions, hemoptysis and progressive breathlessness. Most patients die from respiratory failure within 10 years. There are no controlled studies on
The therapeutic options in the treatment of lung neoplasia usually have not included hormonal therapy, unlike those for primary tumors of other sites (e.g., breast). However, two mesenchymal proliferations of lung, lymphangioleiomyomatosis and epithelioid hemangioendothelioma (EHE), and one
The progression of lymphangioleiomyomatosis, a rare lung disease in women, is thought to be influenced by hormonal factors. We studied the rate of decline in FEV(1) and carbon monoxide transfer factor (TL(CO)) in a national cohort of patients with lymphangioleiomyomatosis in the United Kingdom and
Lymphangioleiomyomatosis (LAM) of the lung is a rare low-grade malignancy affecting primarily women of childbearing age. LAM is characterized by the proliferation of SMA and HMB-45 positive spindle-shaped and epithelioid cells throughout the lung in the form of discrete lesions causing cystic
Lymphangioleiomyomatosis (LAM) is a female-predominant lung disease that can lead to respiratory failure. LAM cells typically have inactivating tuberous sclerosis 2 (TSC2) mutations, leading to mTORC1 hyperactivation. The gender specificity of LAM suggests that female hormones contribute to disease
OBJECTIVE
Lymphangioleiomyomatosis (LAM), a disease affecting women and causing cystic lung lesions, and, in some instances, leading to respiratory failure and death, appears to be exacerbated by estrogens. Hence, hormonal therapy with progesterone is frequently employed; however, efficacy has not
A case of pulmonary lymphangiomyomatosis is reported. A 37-year-old woman was admitted with hemosputum and dyspnea on exertion. Chest roentgenogram revealed diffuse reticulonodular shadows and arterial hypoxemia was present. Pulmonary function tests showed severe restrictive & obstructive
The main problem in the treatment of pulmonary lymphangioleiomyomatosis, which frequently occurs in the reproductive age, is the control of chylothorax and disease progression. We herein report a case of a 62-year-old woman who underwent surgery for recurrent chylothorax. Histologic examination of
Two cases of pulmonary lymphangioleiomyomatosis, with survival between 12 and 28 years are described. Both were treated with medroxyprogesterone acetate with a slight initial improvement in both lung function and exercise tolerance, and no further deterioration during the period of follow-up of
Lymphangioleiomyomatosis (LAM) is defined as an abnormal proliferation of smooth muscles around lymphatics, venules, and brochioles. This article describes our experiences treating a 21-year-old, white female who experienced recurrent shortness of breath during air travel last year. Her episode was
