Keratoakantom ayırıcı tanısında β-katenin ve siklin d1 Ekspresyonunun rolü

Year 2008, Issue: 3, 127 - 131, 01.10.2008

Abstract

Keratoakantom, hızlı büyüme gösteren benign kutanöz bir tümördür. Keratoakantom, skuamöz hücrelikarsinomdan her zaman histopatolojik inceleme ile kolay ayırt edilemez. Bu çalışmada, keratoakantomve skuamöz hücreli karsinomları ayırmada yardımcı olabilecek histopatolojik kriterleri belirlemeyi veimmunohistokimyasal yöntemlerle β-katenin ve siklin D1 ekspresyonlarının ayırıcı tanıdaki yararınısaptamayı amaçladık. Olgular yedi keratoakantom, yedi keratoakantom benzeri skuamöz hücrelikarsinom ve on altı skuamöz hücreli karsinom olmak üzere üç grup olarak incelendi. Klinik özellikleri,lezyon süresi, çapı, ülserasyon varlığı, simetrisite gibi makroskopik bulgular ve mikroskopik bulgularaek olarak β -katenin, siklin D1 ekspresyonu değerlendirildi. Sonuç olarak; ülser varlığı skuamöz hücrelikarsinom lehine, simetrisite ise keratoakantom lehine bir bulgu olarak saptandı. Ek olarak;keratoakantom benzeri skuamöz hücreli karsinom olgularının invazyon alanında; β-katenindemembranöz ekspresyon kaybı görüldü.

Β -catenin and cyclin d1 expression in the differential diagnosis of Keratoacanthoma

Year 2008, Issue: 3, 127 - 131, 01.10.2008

Abstract

Keratoacanthoma is a benign cutaneous tumour which has rapid growth phase. Keratoacanthoma andsquamous cell carcinoma are sometimes difficult to be distinguished by histopathological examination.The purpose of this study was to evaluate the reliability of some of the histopathological criteria usedto make a distinction between squamous cell carcinoma and keratoacanthoma and to determine theimmunohistochemical expression pattern of β-catenin and cyclin D1 between these tumours. Weexamined the histopathological features with the immunohistochemical findings of sevenkeratoacanthomas, seven squamous cell carcinoma resembling keratoacanthomas and 16 cases ofwell differentiated superficial spreading squamous cell carcinoma. We evaluated tumourcharacteristics (duration of the lesions, diameter, ulceration, symmetricity, and microscopicalproperties), and β-catenin, and cyclin D1 expression. In conclusion; presence of ulceration is moreimportant in squamous cell carcinoma, the presence of symmetricity is in favour of keratoacanthoma.Additionally the loss of membranous expression of β-catenin expression at the deeper part of lesionwas found in squamous cell carcinoma resembling keratoacanthoma.
