Scar Sarcoidosis

Sarcoidosis is a multisystem inflammatory disease of unknown aetiology. Skin involvement has been reported in 12%–27% of patients with systemic disease, and scar sarcoidosis is a form of sarcoidosis developing in previous cutaneous scar areas. Scars due to all kinds of trauma, including surgery, vaccines, cosmetic tattoos, and herpes zoster infection, have been reported to be associated with sarcoidosis. Upper eyelid blepharoplasty is a mainstay of aesthetic procedure and of surgical rejuvenation of the orbital region. There have been relatively few reported scar sarcoidosis on blepharoplasty scar, considering many blepharoplasty procedures done for the last century. We report a case of 47-year-old woman presented with abruptly forming bilateral scar sarcoidosis on upper eyelid linear scars of 20 years of duration.

The morphology of the fibroblasts changes markedly as the healing period from burn wounds progresses, through development of the hypertrophic scar, to resolution of the scar by a self-limiting process of maturation or therapeutic resolution. In addition, hypertrophic scars contain an increased cell proliferation largely made up of fibroblasts. This tremendous population of fibroblasts seems congruous with the abundance of collagen and ground substance. The fine structure of these cells should reflect some aspects of the metabolic activity necessary for production of the scar, and might presage the stage of maturation.A comparison of the fine structure of the fibroblasts from normal skin, different scar types, and granulation tissue has been made by transmission (TEM) and scanning electron microscopy (SEM).

Longitudinal Fiber

Dupuytren's Contracture is a nodular proliferation of the longitudinal fiber bundles of palmar fascia with its attendant contraction. The factors attributed to its etiology have included trauma, diabetes, alcoholism, arthritis, and auto-immune disease. The tissue has been observed by electron microscopy and found to contain myofibroblasts.Dupuytren's Contracture constitutes a scar, and as such, excessive collagen can be observed, along with an active form of fibroblast.Previous studies of the hypertrophic scar have led us to propose that integral in the initiation and sustenance of scar tissue is a profusion of microvascular regeneration, much of which becomes and remains occluded producing a hypoxia which stimulates fibroblast synthesis. Thus, when considering a study of Dupuytren's Contracture, we predicted finding occluded microvessels at or near the fascial scarring focus.Three cases of Dupuytren's Contracture yielded similar specimens, which were fixed in Karnovskys fluid for 2 to 20 days. Upon removal of the contracture bands care was taken to include the contiguous fatty and areolar tissue which contain the vascular supply and to identify the junctional area between old and new fascia.
