Lectin-binding sites in clear cell acanthoma (CCA) were studied using an avidin-biotin complex (ABC) with 9 lectins. Formaldehyde-fixed, paraffin-embedded sections of 7 CCA lesions were employed. Positive stainings, similar to those seen in normal epidermis, were observed on the cell surface in CCA
The lectin-binding pattern of malignant and benign human epidermal tumours was studied. Twelve squamous cell carcinomas and ten kerato-acanthomas were investigated, using fluorochrome-conjugated lectins. Lectins used were Canavalia ensiformis agglutinin (Con-A), Helix pomatia agglutinin (HPA),
BACKGROUND
Papular xanthoma (PX) is one of several clinicopathologic variants of normolipemic cutaneous non-Langerhans cell histiocytoses (n-LCH). PX represents a monomorphous reaction pattern of n-LCH characterized by the presence of predominantly xanthomatized macrophages.
