It is also known as terminal villus deficiency.[1]

Features:[1]
- Small, round villi (30-60 micrometers).
- "Long" villi (due to lack of branching).
- Absence of syncytial knotts.
- Wide intervillous space.

PLACENTA AND MEMBRANES, BIRTH: - SMALL PLACENTA FOR GESTATIONAL AGE (265 GRAMS - TRIMMED , POST FIXATION). - FETAL MEMBRANES WITHIN NORMAL LIMITS. - THREE-VESSEL CORD WITHIN NORMAL LIMITS. - PLACENTAL DISC WITH VILLOUS HYPOPLASIA. COMMENT: THE PLACENTAL FINDINGS ARE COMPATIBLE WITH INTRAUTERINE GROWTH RESTRICTION.
