**Core Concept**
Peau d'orange, also known as orange peel skin, is a clinical manifestation characterized by a dimpled, thickened, and inflamed skin appearance. This condition is primarily associated with obstructed lymphatic drainage, leading to accumulation of fluid, proteins, and other substances in the interstitial spaces of the skin.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of peau d'orange, which is often observed in breast cancer, particularly in cases of ductal carcinoma. The cancer cells infiltrate and obstruct the lymphatic vessels, leading to impaired lymphatic drainage. This results in the accumulation of fluid and proteins in the skin, causing it to become thickened, inflamed, and dimpled, resembling the texture of orange peel.

* **Option C:** This option is incorrect because while mastitis is an inflammatory condition of the breast, it is not typically characterized by the development of peau d'orange.
**Clinical Pearl / High-Yield Fact**
It is essential to note that peau d'orange is often associated with malignancies, particularly breast cancer, and its presence should prompt further investigation to rule out underlying cancer.
**Correct Answer: C.**
