Liposarcoma of the chest wall mimicking a breast mass in a man: a case report

Figures

• 

  Fig. 1. Patient's physical examination: Soft lump involving the whole left breast was evident, with no lymph node enlargement

• 

  Fig. 2.1. Mammogram of the left breast cranio-caudal view showing a large well-defined encapsulated fat containing mass (red arrow) with a peripheral dense solid component adjacent to it (white arrow). 2.2. Mammogram of the left breast medio lateral oblique view showing the mass lying within the pectoralis muscle

• 

  Fig. 3. Breast ultrasound. Circumscribed, complex solid-cystic mass with a central fluid-filled area, growing between both pectoral muscles

• 

  Fig. 4. Breast MRI. Axial T2 - weighted image shows large predominantly high -signal mass with thickened and nodular septa (white arrow)

• 

  Fig. 5. Breast MRI. Sagittal T2 -weighted image with fat suppression shows hypointense signal of the fat components of the mass (white arrow) due to fat suppression and hyperintense signal of the necrotic area (red arrow)

• 

  Fig. 6. Breast MRI. Contrast enhanced axial T1 showing enhancement of the septa within the mass (white arrow)

• 

  Fig. 7. Core biopsy microscopy: well-differentiated area of liposarcoma (40x): Histologically, adipose tissue consisting of adipocytes of various sizes (red arrow) with hyperchromatic and enlarged nuclei is observed

• 

  Fig. 8. Surgical specimen microscopy. Transitional zone between well-differentiated (white arrow) liposarcoma and non lipogenic dedifferentiated areas (red arrow) (40x)
