Primary Axillary Tail Malignancy with Nodal Metastatic Disease: A Case Report

The axillary tail of Spence, usually variable in size is a narrow part of breast tissue near the anterior axillary fold which extends into the axilla via the opening in the clavipectoral fascia. The incidence of malignancy from this tissue is rarely reported in literature. Being in close proximity to axilla, lymph nodal involvement is seen early in the disease process. This may result in an axillary lump presentation with no lump in the breast. A high index of clinical suspicion in the absence of a breast lump creates a diagnostic dilemma. The aim of present case study is to describe the presentation and management of primary malignancy of the axillary tail of the breast.
