Figure 3 Histopathological findings. The sample from the syringocystadenoma papilliferum case was submitted to hematoxylin-eosin staining. A: Papilloma-like hyperplasia of the epidermis, with the epidermis partly sinking into the dermis to form several cystic depressions, lined with stratified squamous epithelium (× 40); B: Glandular cavity-like structures in the dermis, with some opened into the epidermis. Large amounts of lymphocytes, neutrophils, and plasma cells were infiltrated in the interstitial area, with splinter hemorrhage (× 100); C: The cavity wall and villous epidermis of the glandular cavity were composed of two layers of epithelial cells; the inner layer included columnar cells, with oval and eosinophilic nuclei and abundant cytoplasm; apocrine secretion was observed (× 200).
