Histopathology of skin damage in traumatic detachment of integumentary tissues
Objective. To analyze the features of skin damage following traumatic detachment of integumentary tissues. Material and methods. Surgical material was analyzed in 5 patients with detachment of integumentary tissues who underwent surgery within 1-7 days after injury. Age of patients ranged from 22 to 69 years. There were 2 patients younger 30 years old and 3 ones aged 31-50 years. We histologically examined the exfoliated tissues, epidermis, dermis, subcutaneous tissue, its arteries and veins, as well as superficial fascia of the thigh. Results. In a series of transverse sections of perforator arteries, we observed patent segments with small amount of thrombotic masses, as well as spasmodic arteries with focal obstructive thrombosis. Saphenous veins and veins of subdermal vascular plexus were thrombosed. We found numerous microscopic tissue gaps between the layers of epidermis, epidermis and dermis, in papillary dermis, between dermis and subcutaneous adipose tissue, in subcutaneous adipose tissue, between subcutaneous adipose tissue and superficial fascia with destruction of subpapillary, dermal and subdermal vascular plexuses, as well as disorders of skin innervation skin, intercellular and cell-stromal interactions. Conclusion. For the first time, a multiple-level damage to skin and vascular plexuses following traumatic detachment of integumentary tissues was established.
