Pulmonary vascular lesions in MCTD.
(Panel A) Severe intimal fibrosis almost occluding the vascular lumen (Elasitica-Goldner stain).
(Panel B) Organized thrombus in medium-sized artery (Elasitica-Goldner stain).
(Panel C) Plexogenic arteriopathy sometimes occurred (Elasitica-Goldner stain).
(Panel D) Vasculitis of small vessels with inflammatory infiltration around vessels almost composed of lymphocytes (Elastica-Goldner stain).
MCTD cases with PH also show the interstitial type, vascular type, and mixed type with both lesions; however, the mixed type is very rare. Further, the vascular type of MCTD shows similar lesions to SSc, such as fibrous thickening, and to SLE, such as plexogenic arteriopathy.آیا می خواهید مدیلیب را به صفحه اصلی خود اضافه کنید؟
