ABSTRACT
ABSTRACT The aim of this study was to investigate whether the histopathological findings of psoriasis varied by the biopsied lesion location. Age, gender, age at disease onset, lesion locations, presence or absence of a preliminary diagnosis of psoriasis, and histopathological findings of 307 patients were recorded. The sections prepared from the patients' paraffin blocks were reexamined microscopically, the severity of the observed findings was graded, and various histopathological features were recorded. The female-to-male ratio was 1.2 to 1. Family history for psoriasis was positive in 30% of patients. A clinically preliminary diagnosis of psoriasis was present in 232 patients. The most common histopathological features included hyperkeratosis, parakeratosis, Munro/Kogoj microabscesses, suprapapillary thinning-hypogranulosis, and vascular dilation-capillary proliferation. Hyperkeratosis was least common in the trunk. A linear and moderately strong correlation was found between the histopathological findings of inflammation, capillary proliferation, and suprapapillary thinning. For the first time, the clinical and demographic features of psoriasis are evaluated and the severity of the histopathological findings is compared by the biopsied lesion location in a large number of patients.
