Abstract

We experienced a case of 63 years old male patient who had synchronous rectus abdominis intramuscular schwannoma and chest wall lipoma. Schwannoma is rare benign tumor which derived from nerve sheath and mainly peripheral nerve of flexor part. The authors report rare synchronous schwannoma and lipoma development.

Figure

• 

  Figure 1. The ultrasonographic finding shows well defined heterogenous echogenic mass.

• 

  Figure 2. (A) Transverse CT image shows well-defined low density soft tissue mass on Rt. anterior chest wall. (B) Transverse CT image shows well-defined mass in rectus abdominis muscle.

• 

  Figure 3. In the gross finding of the intra-muscular mass in rectus abdominis, a round, pink and well-capsulated mass is shown.

• 

  Figure 4. The cross sectional finding of the intra-muscular mass demonstrates multi-septated pattern, scattered hemorrhagic clots and fibrous tissue.

• 

  Figure 5. The histologic examination of hematoxyline and eosin stained specimen shows more cellular "Antoni A" pattern (white arrow) with palisading nuclei surrounding pink areas (Verocay bodies), and "Antoni B" pattern (black arrow) with a looser stroma, fewer cells, and myxoid change (×400).
