Granulomatous mastitis in accessory breast tissue: A rare presentation and surgical management

Granulomatous mastitis (GM) in accessory breast tissue is rare. The present study aimed to report a rare case of GM in accessory breast tissue. A 39-year-old female patient presented with right axillary discomfort and swelling for ~5 days. On clinical examination, a tender, firm lump was detected in the right axillary region. The ultrasound showed diffuse parenchymal heterogeneity and surrounding edema in the right accessory breast associated with reactive axillary lymph nodes. Following unresponsiveness to conservative treatment, a surgical procedure was performed in the form of an excisional biopsy and the lesion was diagnosed as GM. During the six-month follow-up, there were no recurrences. The exact cause of GM remains uncertain and the etiology within accessory breast tissue is even less understood. Proposed mechanisms suggest that it may result from an exaggerated immune response triggered by various factors, such as infection, autoimmunity or hormonal fluctuations. GM in accessory breast tissue is a rare and challenging clinical condition to be diagnosed. Due to the rarity of this condition, it highlights the importance of including GM in the differential diagnosis of axillary masses.

Axillary breast: Navigating uncharted terrain

Introduction:

Axillary breast is a common condition that leads to discomfort and cosmetic problems. Liposuction alone and open excision are two techniques used for treatment.

Materials and Methods:

This study assesses the results of treatment in 24 consecutive patients, operated between 2005 and 2015. All patients had Kajava class IV masses. Three were treated by liposuction alone, while 21 were treated by open axillaplasty with limited liposuction.

Results:

One patient treated by liposuction alone had to be re-operated for a residual lump, while with axillaplasty, no major complications were observed and the results were uniformly good.

Discussion:

Certain points of technique emerged as major determinants in obtaining the best results. In brief, these are: a) limited skin excision; b) placing elliptical incisions within the most lax, apical axillary skin, irrespective of the location of the lump; c) raising skin flaps at the level of superficial fascia; d)meticulous dissection and preservation of the nerves, especially the second intercostobrachial; f) judicious liposuction for eliminating dog ears and axillary sculpting only; g) avoiding drains.

Conclusion:

Open axillaplasty with limited liposuction is the best way to minimise complications and produce good results.
