Peau d’orange.
It literally means “orange peel” in French. Clinically, it’s something we take very seriously.
This skin change looks like dimpling, thickening, or pitting of the breast, giving it that textured, uneven appearance. What’s actually happening underneath is swelling (edema) caused by blocked lymphatic vessels. The skin can’t drain properly, so it tightens and puckers.
Peau d’orange can show up in benign conditions.
Mastitis, engorgement, or localized inflammation can all temporarily disrupt lymph flow and create this appearance.
But, and this is critical,
it is also a classic hallmark of Inflammatory Breast Cancer (IBC).
IBC doesn’t usually present like a typical breast lump. It moves fast. It spreads through the lymphatic system of the skin, which is why the first visible sign is often skin change, not a discrete mass.
Other signs that raise concern when seen with peau d’orange:
•Rapid onset swelling of the breast
•Redness or warmth
•Skin thickening
•Breast feeling heavy or firm
•Ni**le changes or flattening
This is not a “wait and see” situation.
If peau d’orange appears suddenly and doesn’t quickly resolve, especially without clear signs of infection, it needs urgent medical evaluation.
As lactation professionals, parents, and clinicians, it’s easy to assume everything breast-related in the postpartum period is “just mastitis.”
Sometimes it is.
But every once in a while, it’s not.
Knowing the difference and acting quickly matters.
