Abstract

Granular cell tumors (GCTs) are uncommon benign neurogenic tumors that can be found at any site in the body including the tongue, skin, subcutaneous tissue, breast, gastrointestinal, and urogenital systems. We report here the CT and ultrasonographic findings of a case of granular cell tumor that occurred in the abdominal wall of a 44-year-old woman.

Keywords: Granular Cell Tumor, Abdominal Wall, Ultrasonography, Tomography, X-Ray Computed

Figures and Tables

Fig. 1

44-year-old woman with incidental mass in anterior abdominal wall.

A. Noncontrast axial CT image shows 1.4 cm sized round mass (arrow), in subcutaneous space, which abuts on left rectus abdominis muscle and shows homogenous isoattenuation with rectus abdominis.
B. Sagittal image of contrast enhanced CT shows a round, homogenously enhancing mass (arrow) protruding anterior to rectus abdominis muscle.
C. Abdominal ultrasonography shows a spiculated, ill-defined and markedly hypochoic mass with posterior acoustic shadowing and surrounding hyperechoic halo (arrows).
D. Color Doppler US image shows hypovascularity of the mass.
E. Microscopically, proliferation of polygonal to spindle shaped cells devided by fibrous septa, eccentrically located nuclei and eosinophilic granular cytoplasm (H & E; ×400).
F. Immunohistochemsitry examination shows strong reactivity for S-100 protein.
