A New Case of Syringocystadenocarcinoma Papilliferum: A Rare Pathology for a Wide-Ranging Comprehension
Figure 2
Analysis of a skin syringocystadenocarcinoma papilliferum specimen. (a) p63 antibody stains the transition area from epidermis epithelium to the squamous neoplasm and the basal layer of glandular component (original magnification ×40). (b) The papillary structures are moderately positive and/or negative for p63 (original magnification ×100). (c) Immunohistochemical staining demonstrates c-kit at the basal layer of neoplastic budding; almost negative, only with speckled positive cells, is the squamous solid component (original magnification ×20). (d) A few positive cells of the squamous neoplasia are stained by Nestin antibody, stemness marker (original magnification ×400).
