Cutaneous Metastases in Breast Cancer: An Obsolete Concept?

While cutaneous metastases from breast cancer are still a relevant concern, the concept of "obsolete" cutaneous breast cancer is not entirely accurate. However, it's essential to understand that the terminology and classification of cutaneous metastases have evolved over time.

Historical Context In the past, cutaneous metastases were often referred to as "cutaneous carcinomatosis" or "carcinoma en cuirasse." These terms described a rare and aggressive form of breast cancer that presented with widespread skin involvement (Salem, 2023 [5]; Nguyen, 2021 [9]). This condition was associated with a poor prognosis and limited treatment options.

Current Understanding Today, cutaneous metastases from breast cancer are recognized as a distinct entity, often referred to as "cutaneous metastatic breast cancer" (CMB) or "breast cancer cutaneous metastases." These metastases can occur in up to 23.9% of individuals with breast carcinoma (Salem, 2023 [11]). The clinical presentation and management of CMB have been refined, and it is now considered a therapeutic challenge.

Key Points

• Cutaneous metastases from breast cancer are still a relevant concern.
• The concept of "obsolete" cutaneous breast cancer is not entirely accurate.
• The terminology and classification of cutaneous metastases have evolved over time.
• Cutaneous metastatic breast cancer (CMB) or breast cancer cutaneous metastases are recognized as distinct entities.

I couldn't find any information on "obsolete cutaneous breast cancer." However, I can provide you with some general information on signs and symptoms of breast cancer that may be relevant.

Breast cancer is a type of cancer that affects the breast tissue. It's not typically referred to as "cutaneous" (which refers to the skin), but rather as a tumor or growth in the breast tissue.

That being said, if you're looking for information on signs and symptoms of breast cancer, here are some common ones:

• A new lump or thickening in the breast
• A change in the size or shape of the breast
• A dimpling or puckering of the skin on the breast
• An itchy or scaly sensation on the nipple or surrounding area
• Redness or swelling of the breast
• Nipple discharge (other than breast milk)
• Changes to the nipple, such as retraction or inversion

Keep in mind that these symptoms can also be caused by other conditions, and not all women with breast cancer will experience them. If you're concerned about your health, it's always best to consult a healthcare professional for personalized advice.

Diagnostic Tests for Obsolete Cutaneous Breast Cancer

Cutaneous metastases from breast cancer are a rare but serious condition, where cancer cells have spread to the skin. Diagnosing this condition requires a combination of clinical examination and diagnostic tests.

• Clinical Core and Cutaneous Punch Biopsies: These biopsies remain a valuable tool in diagnosing breast cancer, particularly in managing clinically suspicious cases [6][8]. A core needle biopsy involves using a specialized gun to collect tissue samples from the affected area.
• Skin Biopsy: A skin biopsy is often used to confirm the diagnosis of cutaneous metastases. This test involves taking a small sample of skin tissue for examination under a microscope [13].
• Imaging Tests: Imaging tests such as mammography, ultrasonography, and breast magnetic resonance imaging (MRI) may be used to evaluate breast lesions and detect cancer at an early stage [2][4]. However, these tests are not typically used to diagnose cutaneous metastases.
• Staging Tests: If breast cancer is diagnosed, staging tests are done to find out if cancer cells have spread within the breast or to other parts of the body. This process is called staging [12].

It's worth noting that research shows that cutaneous metastases occur in around 10 percent of cancer cases with solid tumors, such as breast cancer [11]. Cutaneous MBC accounts for just over half of these cases.

Treatment Options for Cutaneous Metastases in Breast Cancer

Cutaneous metastases, also known as skin metastases, are a common occurrence in patients with advanced breast cancer. While there is no cure for this condition, various treatment options can help manage symptoms and improve quality of life.

• Imiquimod: This topical cream has been shown to be effective in treating cutaneous metastases from breast cancer (Nguyen, 2021). Imiquimod works by stimulating the immune system to attack cancer cells.
• Miltefosine: A topical cytostatic agent that targets cell membranes and inhibits protein kinase C, thereby halting cell differentiation. It has been used in clinical trials to treat cutaneous metastases from breast cancer (Conlin, 2022).
• Tucatinib: This oral medication shows evidence of efficacy against cutaneous metastasis, which is common and difficult to control for patients with HER2-overexpressing MBC (Conlin, 2022).

Other Treatment Options

While these treatments have shown promise, it's essential to note that each patient's response may vary. Other treatment options, such as chemotherapy, hormone therapy, or targeted therapy, may also be considered on a case-by-case basis.

• Chemotherapy: Various chemotherapy drugs can be used to treat breast cancer, including single agents or combination therapies (Kurtyka, 2021).
• Hormone Therapy: For patients with hormone receptor-positive breast cancer, hormone therapy may be an option.
• Targeted Therapy: Targeted therapies, such as trastuzumab, can be effective in treating HER2-positive breast cancer.

Differential Diagnosis of Cutaneous Breast Cancer

Cutaneous metastases of breast cancer are a rare but serious condition, where cancer cells from the breast spread to the skin. The differential diagnosis of this condition involves identifying other possible causes of skin lesions that may mimic breast cancer metastasis.

Rare Diagnoses

According to search results [1], [2], and [3], primary ectopic mammary carcinoma (a rare type of breast cancer that occurs outside the breast) and cutaneous metastatic breast cancer of unknown primary are exceedingly rare diagnoses. The location of the lesion, specifically in the axillae, supports the former diagnosis as ectopic breast cancer is most commonly reported in this area [1], [2], and [3].

Other Possible Causes

In addition to these rare diagnoses, other malignancies can also present with cutaneous metastases, including primary cutaneous lymphomas, Merkel cell carcinoma, Kaposi sarcoma, adnexal tumors, and metastatic cancers to the skin [6]. A skin biopsy is essential in differentiating between these conditions.

Importance of Early Diagnosis

Early diagnosis of skin metastases often initiates treatment or dramatically changes previously used therapeutic regimens that can prolong patient survival [12]. Therefore, it is crucial for dermatologists to consider cutaneous metastases suggestive of breast cancer in their differential diagnosis, especially when dealing with nonresponsive cutaneous lesions.

Diagnostic Tools

Currently, there are three commercially available RNA-based molecular platforms for the diagnosis of carcinoma of unknown primary [14]. Although none specifically detect cutaneous apocrine carcinoma, they can identify breast cancer among other tumors. This highlights the need for further research and development of diagnostic tools to aid in the differential diagnosis of cutaneous metastases.

Awareness and Consideration

The fact that a nonspecific cutaneous lesion may hide an advanced-stage cancer that becomes multisystemic even before symptoms appear, must raise awareness of the importance of considering malignancies as silent causes of nonresponsive cutaneous lesions [15]. Cutaneous metastases of breast cancer are a serious condition that requires prompt attention and accurate diagnosis.
