Abstract

BACKGROUND: In lipodystrophies of the anterior abdominal wall, variables such as genetic factors, weight gain, age, and loss of muscle tone, either alone or in combination, determine generalized aesthetic changes or changes localized in the epigastrium, hypogastrium, or both. The aim of this study was to describe the limits, distribution, and dimensions of fat bags in the hypogastrium, as well as their anatomic relationships with the neighboring structures. METHODS: Fifty-seven anatomical specimens were dissected from patients undergoing abdominoplasty, during which the hypogastrium was resected en bloc. Moreover, the anterior abdominal wall was also dissected in 8 cadavers. In all samples, the lamellar layer was resected, keeping the dermis-epidermis, areolar layer, and superficial fascia intact. RESULTS: In all specimens, 2 symmetrical adipose clusters were observed bilaterally in the areolar layer, which were in the shape of a bag and had peculiar coloration. These bags were analyzed in relation to their neighboring tissues: the skin, superficial fascia, and deep fat layer. CONCLUSIONS: The lamellar layer was considered as a structural base of the skin, owing to its thinness. The areolar layer showed accumulations and varying amounts of fat in the various body regions without precise limits, which were particularly observed in dissections of the lower abdominal wall and identified by their elasticity, volume, and coloration.

Highlights

Subcutaneous fat deposits in the form of dense bags lo cated in the anterior abdominal wall have been referred to as esteatomas[1] and are more commonly found in women[2]

Summary

Introduction

Subcutaneous fat deposits in the form of dense bags lo cated in the anterior abdominal wall have been referred to as esteatomas[1] and are more commonly found in women[2]. In very obese patients or patients who have undergone major weight loss, macro and microscopic changes occur in the structure of both layers of the adipose tissue as well as the superficial fascia In these patients, localization of the adipose bags is not evident because of the fragmentation of the fascia and invasion by fatty lobes in the lamellar and areolar layers[3]. Results: In all specimens, 2 symmetrical adipose clusters were observed bilaterally in the areolar layer, which were in the shape of a bag and had peculiar coloration These bags were analyzed in relation to their neighboring tissues: the skin, superficial fascia, and deep fat layer. The areolar layer showed accumulations and varying amounts of fat in the various body regions without precise limits, which were observed in dissections of the lower abdominal wall and identified by their elasticity, volume, and coloration
