PPHP stands for:

PPHP stands for:

• A. Pseudo-pseudohypoparathyroidism
• B. Pseudohypoparathyroidism Type II
• C. Primary pseudohypoparathyroidism
• D. Pseudoparathyroidism

Answer: (A)

PPHP stands for pseudo-pseudohypoparathyroidism. The name reflects a situation where the person has the physical features associated with pseudohypoparathyroidism (such as Albright hereditary osteodystrophy) but with normal calcium, phosphate, and PTH levels—so there isn’t true resistance to PTH. The double “pseudo” implies a resemblance to pseudohypoparathyroidism in appearance, without the biochemical hallmarks of PTH resistance. In contrast, true pseudohypoparathyroidism involves PTH resistance with low calcium and high phosphate. The other terms are either different subtypes or nonstandard labels that don’t capture this specific combination of phenotype without biochemical abnormalities.
