Sebaceous gland carcinoma usually arises from meibomian or Zeis glands
deep within the eyelid, but it can rarely arise within the conjunctival epithelium
without a deep component. We describe a woman with a history of chronic blepharoconjunctivitis
unresponsive to topical medications. Examination disclosed confluent papillary
hypertrophy of the upper palpebral conjunctiva and deposits of white flaky
material. Tarsoconjunctival punch biopsy revealed intraepithelial sebaceous
gland carcinoma. Management consisted of frozen sectioncontrolled complete
tumor excision with removal of the entire posterior lamella of the right upper
eyelid, cryotherapy to the margins, and reconstruction. Histopathologic analysis
confirmed primary sebaceous gland carcinoma localized to the conjunctival
epithelium without involvement of underlying meibomian or Zeis glands or the
caruncle. Patients with unexplained chronic unilateral blepharoconjunctivitis
or papillary hypertrophy of the palpebral conjunctiva should be considered
for biopsy to rule out neoplasia, even when there is no sign of an underlying
eyelid mass.
