PATHOMORPHOLOGICAL ASPECTS OF CHANGES IN SKIN STRUCTURES IN PLANTAR PSORIASIS

This article analyzes the pathomorphological changes of skin structures in plantar psoriasis. The study revealed pronounced hyperkeratosis, parakeratosis, acanthosis, shortening or loss of the granular layer, and elongation of epidermal ridges. The anatomical features of the plantar skin contribute to the specific clinical manifestations of these pathomorphological signs. The obtained data are of significant importance for a deeper understanding of the pathogenesis of plantar psoriasis and for improving differential diagnosis.本文针对跖部银屑病（plantar psoriasis）患者皮肤结构的病理形态学变化展开分析。研究观察到显著的角化过度（hyperkeratosis）、角化不全（parakeratosis）、棘层肥厚（acanthosis），颗粒层（granular layer）缩短或缺失，以及表皮嵴（epidermal ridges）伸长。跖部皮肤的解剖学特征使得此类病理形态学征象呈现出特异性临床表现。本研究所得数据对于深入理解跖部银屑病的发病机制（pathogenesis）以及优化鉴别诊断（differential diagnosis）均具有重要价值。
