Tail of Spence

Illu lymph chain03

Tail of Spence (also known as the axillary tail of Spence or axillary process) is an extension of the tissue of the breast that extends into the axilla (armpit). It is named after the British surgeon James Spence, who first described it in the 19th century. This anatomical feature is significant in both the physiology and pathology of the breast, playing a role in conditions such as breast cancer and in surgical procedures related to the breast.

Anatomy

The Tail of Spence is situated in the upper outer quadrant of the breast, extending laterally across the anterior axillary fold. It is composed of glandular tissue and adipose tissue, similar to the rest of the breast. This area is rich in lymphatic vessels, making it a common route for the spread of breast cancer to the lymph nodes of the axilla. The presence of breast tissue in this area can vary greatly among individuals, with some having a pronounced Tail of Spence, while in others, it may be less noticeable.

Clinical Significance

The Tail of Spence is an important consideration in both the diagnosis and treatment of breast diseases. Its proximity to the axillary lymph nodes means that it is a key area for the spread of breast cancer. During clinical examinations and imaging studies, such as mammography and ultrasound, special attention is given to this region to detect any abnormalities.

In breast cancer treatment, the Tail of Spence is often examined during surgical procedures like mastectomies and sentinel lymph node biopsies to ensure the complete removal of cancerous tissue. The anatomy of the Tail of Spence can also influence the surgical approach and the extent of tissue removal.

Breast Cancer Awareness

Awareness of the Tail of Spence is crucial in breast cancer education and self-examination practices. Individuals are encouraged to include this area when performing self-examinations for lumps or other changes, as cancers can develop in this part of the breast.

Surgical Considerations

In cosmetic and reconstructive breast surgery, understanding the anatomy of the Tail of Spence is essential for achieving natural-looking results and for the placement of breast implants. Surgeons must consider the distribution of breast tissue in this area to ensure symmetry and to minimize the risk of complications.

Conclusion

The Tail of Spence is a significant anatomical feature of the breast with implications for the diagnosis and treatment of breast diseases, particularly breast cancer. Its recognition is important in clinical practice, breast cancer awareness, and surgical procedures involving the breast.
