THE OFTEN SUPERFICIAL SHAVE BIOPSY
A shave biopsy of the sole may be effective in taking all the tissues that are needed for an unequivocal pathologic diagnosis. If the lesion has small or moderate amount of horny layer, the shave will bring all layers of viable tissue that represent the disease to be diagnosed. Contrariwise, if the lesion has a thick horn, often only such horn is sampled while the underlying tissues, i.e., epidermis and dermis, are left out, regardless of the apparently adequate look of the specimen at first glance.
IPERPLASIA ANGIOLINFOIDE CON EOSINOFILIA
Caso clinico
Fig 1
Donna di 55 anni, presenta da circa due anni alla nuca lesioni papulo-nodulari eritematose, asintomatiche, in lento accrescimento. Alcuni elementi tendono a confluire in placche (Fig. 1,2). L’esame istologico mostra una proliferazione di vasi con cellule endoteliali di aspetto epitelioideo o istiocitoide, con tendenza alla protrusione endoluminale (Fig. 3,4,5). Si associa un denso infiltrato linfocitario perivasale ricco di eosinofili.
