The histotopographic features of formation of keloid scars of maxillofacial localization.
Wiad Lek. 2020; 73(3):565-568.WL

Abstract

OBJECTIVE

The aim: Study of the influence of local oxygen deficiency on the features of the formation of keloid scars of the head and neck.

PATIENTS AND METHODS

Materials and methods: The research material was 17 incisional biopsy specimens of keloid scars, which were the highest age categories of patients from 19 to 63 years.

RESULTS

Results: It was revealed that at coloring according to Mallory's technique, sections of fibrinoid swelling of collagen fibers were noted near central homogeneous hyaline masses. The lateral areas of the dermis that adjacent to keloid scar tissue, at coloring by the Hart method, in our modification, were characterized by the separation of the hyalinosis zone from the undamaged dermis by coarse bundles of elastic fibers that are colored in dark purple. The undifferentiated dysplasia of the connective tissue has caused the replacement and obstruction of single vascular components, which has complicated the local oxygen deficiency of keloid-altered tissues.

CONCLUSION

Conclusions: Thus, plasmaragia and the accumulation of protein deposits in the perivascular space determine the inhibition of local hemodynamics, which explains the decrease in oxygen transport to tissues. Decreased oxygenation and increased permeability of the vascular wall causes local hemocirculatory hypoxia.
