| Adenocarcinoma
of sebaceous glands presents as a wide spectrum of clinical appearances
and can be easily mis-diagnosed as a more common entity such as a
chalazion or a chronic blepharoconjunctivitis (#21861) (#21862). The upper eyelid is most common site of sebaceous CA in the
body. These tumors can arise
from the meibomian glands or the glands of Zeis.
Histologically, the degree of cellular anaplasia varies (#21864).
Poorly differentiated tumors can be mistaken for squamous or basal
cell carcinoma. Many of the
tumor cells stain positively for fat, which makes lipid staining of frozen
tissue important (#21865). These
tumors are potentially agressive and may metastasize.
