Angiolymphoid hyperplasia with eosinophilia in the skin[ALH] A clinical, histopathological and ultrastructural study

ABSTRACT

Two cases of angiolymphoid hyperplasia with eosinophilia were studied clinically, histologically and ultrastructurally. Clinically, the patients were mainly young females with tumors ranging 4-5 mm in diameter, localization mainly to the head. Histologically, the tumors showed the unusual combination of poorly differentiated proliferating vessels, tissues eosinophilia, and lymph histocytic infiltrate and arteritis. Ultrastructural study revealed the histocytic qualities of the endothelial cell that constitutes much of the tumor. It was believed that both the vascular and the histocytic qualities of this cell population are characteristic and are helpful in diagnosis. The lesions were apparently benign and can usually be cured by excision
