Mucinous carcinoma of the breast is a rare type of breast cancer characterized by the presence of mucin-producing cancer cells. This type of carcinoma is also known as colloid carcinoma. It accounts for approximately 2-3% of all breast cancer cases.

Pathophysiology

Mucinous carcinoma of the breast is distinguished by the production of mucin, a gelatinous substance, by the cancer cells. The mucin surrounds the cancer cells, forming clusters that can be identified under a microscope. This type of carcinoma typically has a slower growth rate compared to other forms of breast cancer and is often less aggressive.

Clinical Presentation

Patients with mucinous carcinoma of the breast may present with a palpable mass in the breast. The mass is usually well-defined and may feel soft or rubbery due to the mucin content. Other symptoms can include changes in the shape or size of the breast, skin dimpling, or nipple discharge.

Diagnosis

The diagnosis of mucinous carcinoma of the breast is typically made through a combination of mammography, ultrasound, and biopsy. Imaging studies may show a well-circumscribed mass, and a biopsy will reveal the characteristic mucin-producing cancer cells.

Treatment

Treatment options for mucinous carcinoma of the breast are similar to those for other types of breast cancer and may include surgery, radiation therapy, chemotherapy, and hormone therapy. The choice of treatment depends on the stage of the cancer, the patient's overall health, and other factors.

Prognosis

The prognosis for patients with mucinous carcinoma of the breast is generally favorable, especially when the cancer is detected early. This type of carcinoma tends to have a lower rate of metastasis and a higher survival rate compared to other forms of breast cancer.

Epidemiology

Mucinous carcinoma of the breast is more commonly diagnosed in older women, typically those over the age of 60. It is less common in younger women and men.
