Scar masses from granulation tissue
Question A 50 years old Male known with a diagnosis of ulcerative colitis since October 2012 (Montreal Class E3) was seen for further follow up in gastroenterology outpatient. He was on Meselazine 2.4 gm per day. The last flare up he had was 2.5 years ago in April 2013 when he was treated successfully with a course of oral steroids. His colitis has been in a stable state with no further flare u...
متن کاملCharacterization of fibroblast clones from periodontal granulation tissue in vitro.
Connective tissues are known to be composed of heterogeneous fibroblast subpopulations. The significance of this heterogeneity in different physiological and pathological conditions is poorly understood. Granulation tissue is formed in connective tissue during wound healing, chronic inflammation, and certain pathological conditions. In this study, heterogeneity of fibroblasts from granulation t...
متن کاملEvidence for the nonmuscle nature of the "myofibroblast" of granulation tissue and hypertropic scar. An immunofluorescence study.
Contraction is an important phenomenon in wound repair and hypertrophic scarring. Studies indicate that wound contraction involves a specialized cell known as the myofibroblast, which has morphologic characteristics of both smooth muscle and fibroblastic cells. In order to better characterize the myofibroblast, the authors have examined its cytoskeleton and surrounding extracellular matrix (ECM...
متن کاملActinomyces associated with persistent vaginal granulation tissue.
BACKGROUND We report a case of symptomatic actinomycosis associated with vaginal suture erosion and granulation tissue refractory to conservative management, in an outpatient setting. CASE Three months after total vaginal hysterectomy and uterosacral ligament vaginal vault suspension, a woman complained of painless, intermittent vaginal discharge and spotting. Despite cauterization of granula...
متن کاملGranulation Tissue as a Contractile Organ
CONTRACTING GRANULATION TISSUES CONTAIN FIBROBLASTS THAT DEVELOP CHARACTERISTICS TYPICAL OF SMOOTH MUSCLE: (a) They contain an extensive cytoplasmic fibrillar system. (b) They show immunofluorescent labeling of their cytoplasm with human anti-smooth muscle serum. (c) The nuclei show complicated folds and indentations, indicative of cellular contraction. (d) There are cell-to-cell and cell-to-st...
متن کاملWound splinting regulates granulation tissue survival.
PURPOSE Fibroblast survival within an in vitro collagen matrix is dependent on matrix anchorage to a rigid substratum. The purpose of this study was to determine whether granulation tissue survival in vivo also is dependent on matrix anchorage. We hypothesized that splinting an excisional wound (i.e., anchoring the wound edges) would promote granulation tissue survival and that desplinting a sp...
