Serous tubal intraepithelial carcinoma
Diagnosis in short

Micrograph showing serous tubal intraepithelial carcinoma. H&E stain.
LM three of the following five: (1) atypical chromatin pattern, (2) nuclear enlargement, (3) nuclear pleomorphism, (4) nuclear moulding, (5) loss of nuclear polarity or epithelial stratification
IHC p16 +ve, p53 +ve, Ki-67 increased
Molecular BRCA1 mutation or BRCA2 mutation
Gross not apparent on gross
Site fallopian tubes
Symptoms none
Prevalence uncommon

Serous tubal intraepithelial carcinoma, abbreviated STIC[1] (pronounced stick), is considered to be the precursor of serous carcinoma.

It is also known as tubal intraepithelial carcinoma.

General

  • Considered the precursor lesion for tubal serous carcinoma.[2]
  • Seen in ~6% of prophylactic salpingo-oophorectomies in BRCA-mutation carriers.[3]

Gross

  • Not apparent on gross.
  • Usually at the fimbriated end of the tube.

Microscopic

Features:[4]

  • Discrete papillary growth - low power.
  • Formal criteria - need 3 or more:
    1. Atypical chromatin pattern.
    2. Nuclear enlargement.
    3. Nuclear pleomorphism.
    4. Nuclear moulding.
    5. Loss of nuclear polarity or epithelial stratification.

Notes:

  • At low power STIC is usually tall cells that are too blue.
  • Cilia suggest benign.
