What is indicated by the presence of peau d'orange skin in a client with infiltrating ductal carcinoma of the breast?

The presence of peau d'orange skin in a client with infiltrating ductal carcinoma of the breast indicates inflammation in the breast tissue. This characteristic skin change is typically caused by lymphatic obstruction due to breast cancer. The term "peau d'orange" describes a dimpled, orange peel appearance of the skin, which occurs when the skin thickens and becomes edematous due to the accumulation of lymphatic fluid and the involvement of the skin in the cancer process.

In cases of infiltrating ductal carcinoma, which is the most common type of breast cancer, the cancer can invade surrounding tissues, including lymphatics. When the cancer affects normal lymphatic drainage, it leads to swelling and the distinct texture of the skin. Recognizing peau d'orange is clinically significant, as it may indicate a more advanced disease and necessitate prompt medical evaluation and potentially aggressive treatment.
