Abstract

Objective: Differentiation of eczema and psoriasis can be difficult clinically and histopathologically. In this study, it is designed to evaluate the histological features and bcl-2 expression of cases clinically prediagnosed with psoriasis and eczema in our pathology deparment of Şişli Etfal Training and Research Hospital. Material and Methods: The biopsy results with psoriasis and eczema of 80 cases that clinically prediagnosed with psoriasis and eczema were collected from pathology archives. All biopsies were interpreted by two different dermatopathologists blinded clinical diagnosis and data collection forms were completed. Then data obtained were analyzed by SPSS.Results: There were histopathologic difference between palmoplantar psoriasis and eczema. Hypogranulosis (p=0.001; p<0.01), Munro's microabscess (p=0.001; p<0.01), tortuous blood vessels in papillary dermis (p=0.001; p<0.01), suprapapillary plate thinning (p=0.001; p<0.01), plasma mounds (p=0.033; p<0.05), parakeratosis (p=0.001; p<0.01) ve kogoj (p=0.001; p<0.01) were found that statistically significant contributors for clinicopathological concordance in cases of psoriasis. Spongiosis (p=0.001; p<0.01), spongiotic vesicle (p=0.001; p<0.01), eosinophil infiltration in upper dermis (p=0.001; p<0.01) were significantly associated with diagnosis of eczema. In immunohistochemical studies, while it is found that bcl-2 expression is negative in psoriasis, it is showed that bcl-2 expression in eczema is positive and same intensity as much as bcl-2 expression of normal skin (p=0.001; p<0.01).Conclusion: Histopathologic finding like hypogranulosis, Munro's microabscess, tortuous blood vessels in papillary dermis, suprapapillary plate thinning, plasma omunds, parakeratosis and kogoj had significant associated with psoriasis and might be utilized in establishing its diagnosis. The differentiation between psoriasis and eczema can be made by bcl-2 immunohistochemical study.

Özet

Amaç: Psöriasisin ve egzemanın klinik ve histopatolojik olarak ayrimi zor olabilir. Bu çalışmada, ön tanıları psöriasis ve egzema olarak değerlendirilen olguların histolojik özellikleri ve bcl-2 ekspresyonları Şişli Etfal Eğitim ve Araştırma Hastanesi Patoloji Bölümü tarafından değerlendirilmiştir.Gereç ve Yöntemler: Patoloji arşivinden klinik ön tanıları psöriasis ve egzema olan 80 olgunun biyopsi sonuçları toplandı. Tüm biyopsiler 2 farklı dermatopatolog tarafından klinik tanıları bilinmeden değerlendirildi ve verileri toplandı. Elde edilen veriler SPSS ile analiz edildi.Bulgular: Palmoplantarpsöriasis ile egzema arasında histopatolojik farklar vardır. Hipogranülasyon (p=0.001; p<0.01), Munromikroabseleri (p=0.001; p<0.01), papillerdermiste kıvrımlı kan damarları (p=0.001; p<0.01), suprapapiller tabakada incelme (p=0.001; p<0.0001), plazma tepecikleri (p=0.033; p<0.005), parakeratoz (p=0.001; p<0.01) ve kogoj (p=0.001; p<0.01) bulguları psöriasis olgularının histopatolojik özelliklerine uyumlu olarak istatistiksel olarak anlamlı bulunmuştur. Spongioz (p=0.001; p<0.01), spongiotik vezikül (p=0.001; p<0.01), üst epidermiste eozinofil infiltrasyonu (p=0.001; p<0.01) egzema tanısı ile anlamlı olarak ilişkilendirilmiştir. Bcl-2 ekspresyonu ile yapılan immunohistokimyasal çalışmada psöriasiste bcl-2 ekspresyonu negatif bulunurken, egzema olgularında normal deri ekspresyonu ile aynı şiddette ve pozitif ekspresyon göstermiştir.Sonuç: Hipogranülasyon, Munro mikroabseleri, papiller dermişte kıvrımlı kan damarları, suprapapiller tabakada incelme, plazma tepecikleri,parakeratoz ve kogoj gibi histopatolojik bulgular anlamlı olarak psöriasis ile ilişkili olup, tanı koymada kullanılabilir. Bcl-2 immunohistokimyasal çalışması ile de psöriasis ve egzema ayrımı yapılabilir.
