Histopathology of the tumor shows (b) stratified squamous keratinized lining with dermal adnexae [HE, ×20], (c) lacrimal gland acini with adipose tissue [HE, ×20], (d) tissues of mesodermal origin: skeletal muscle and adipose tissue [HE, ×20], and (e) hair shaft appearing as a refractile structure (black asterix) inciting a foreign-body reaction [HE, ×400], (f) Lacrimal gland (left bottom corner) showing tissues from all three germlines: adipose tissue (mesoderm), stratified squamous epithelium with lamellated keratin (ectodermal, top right), and ducts (endoderm, just above the lacrimal gland on the right bottom) [HE, ×20] |
