YOSHINORI KAWABATA TAMIKO TAKEMURA AKIRA HEBISAWA YUTAKA SUGITA TAKASHI OGURA SONOKO NAGAI FUMIKAZU SAKAI TETSU KANAUCHI THOMAS V. COLBY THE DESQUAMATIVE INTERSTITIAL PNEUMONIA STUDY GROUP 《Respirology (Carlton, Vic.)》2012,17(8):1214-1221
Background and objective: In some patients, desquamative interstitial pneumonia may progress to lung fibrosis. The aim of this study was to assess the long‐term radiological follow‐up results in patients with desquamative interstitial pneumonia. Methods: Among 75 patients suspected of having desquamative interstitial pneumonia, 31 who fulfilled the criteria were included in this study. Clinical characteristics at presentation, responses to treatment and long‐term follow‐up were evaluated. Results: The 31 patients were predominantly males (94%), and the mean age was 55 years; 93% (28/30) had a history of smoking. The clinical findings included high serum levels of lactate dehydrogenase and immunoglobulin G. Bronchoalveolar lavage (26 patients, 84% of cases) frequently showed an increased percentage of eosinophils (mean 17%). Computed tomography (CT) or high resolution (HR) CT at presentation showed ground glass opacities and/or consolidation in all patients, with one third of patients also showing thin‐walled cysts within the ground glass opacities. There was no honeycombing on CT or HRCT scans at presentation. Corticosteroid therapy was effective early in the course of the disease; long‐term follow‐up (mean 99 months) of 31 patients showed only one death due to progression of the disease, but long‐term follow‐up of 14 patients (mean 125 months) by HRCT showed the development of new thin‐walled cysts and honeycombing in five and lung cancer in four patients, respectively. Conclusions: In a proportion of patients, desquamative interstitial pneumonia may progress to lung fibrosis with honeycombing on HRCT, despite therapy. 相似文献

Endometriosis is a condition in which endometrium or endometrium‐like tissue grows in areas other than the endometrium and is often found within the pelvis such as in the uterus or ovary, but occasionally develops ectopically in the skin. In this paper, we report a case of cutaneous endometriosis in the umbilical region found in a 37‐year‐old woman with no history of pregnancy. The lesion was a brown, firm and elastic nodule, 9 mm × 7 mm in size, and caused bleeding as well as pain which increased during menstruation. Histopathological findings revealed that there were small and large glandular cavity structures in the dermis and the edematous interstitium around it. On immunohistochemical staining for estrogen and progesterone receptors, the cellular nuclei of glandular cavity walls were mainly found to be positive for both, and cells in the edematous interstitium around the glandular cavity were positive for CD10. Consequently, we diagnosed this case as cutaneous endometriosis in the umbilical region. CD10 was initially described as a tumor‐specific antigen found in acute lymphoblastic leukemia. Recently, the usefulness of CD10 in diagnosing endometriosis in addition to various types of lymphoma or blood cancer has been confirmed, and in our case it also proved to be as useful as estrogen receptor or progesterone receptor in the definitive diagnosis of endometriosis. 相似文献
