MRI showed a 50 mm low intensity well-demarcated lesion on T1-weighted image(a) and a high intensity lesion on T2-weighted image (b).

T2 high indicating a low fat content (Fig. 1a, b). These investigations could not provide a definitive diagnosis. Trans-inguinal surgical excision confirmed 50 mm tumor located in the inguinal canal with a clear surface and a thin capsule (Fig. 2a).
The cut surface was white, smooth, and glistening, without necrosis or hemorrhage.

T2 high indicating a low fat content (Fig. 1a, b). These investigations could not provide a definitive diagnosis. Trans-inguinal surgical excision confirmed 50 mm tumor located in the inguinal canal with a clear surface and a thin capsule (Fig. 2a). Necrosis, hemorrhage and cystic lesion was not noted (Fig. 2b).
On histology, the lesion was characterized by oval or spindle fibroblastic cells (a). The tumor cells showed immunopositivity for CD34 (b) and desmin (c).

Histopathology reported the tumor had oval and spindle shaped fibroblastic cells with rich collagen deposition (Fig. 3a). Staining for ER, CD34 (Fig. 3b), desmin (Fig. 3c), and CD10 was positive, but alpha-smooth muscle actin and S-100 was negative.
