case_images: Case 1. (a) Appearance of the intrascrotal tumor: The masses were located in the midline of the scrotum and independent of the testes. (b) MRI: T2-weighted axial (b1) and coronal (b2) images. The tubular mass extended from the scrotum to the pelvic floor with complete penetration of the penile corpora cavernosa. White arrow: tumor; black arrow: penile corpora cavernosa. (c) Operative findings: The thick tumor completely penetrated the left penile corpora cavernosa. White arrow: tumor; black arrow: penile corpora cavernosa. (d) Excised specimen: The peripheral (right) and central (left) parts of the tumor across the penile corpora cavernosa were excised separately. Black line: 10 mm. (e) Histopathological examination: The cyst walls were lined with stratified squamous epithelium without malignant changes. Hematoxylin and eosin (H&E) staining; magnification x100.

case_images: A 4-year-old otherwise healthy boy presented to our hospital with a painless, rapidly enlarging tumor in the scrotum (Fig. 1a). The tumor had completely penetrated the corpora cavernosa (Fig. 1b1,b2). Once the tumor was identified and detached from the surrounding tissues, it was found to have penetrated the left penile corpora cavernosa (Fig. 1c). The peripheral and central sides of the tumor across the penile corpora cavernosa were excised (Fig. 1d). Pathological examination revealed a cystic lesion lined with stratified squamous epithelium (Fig. 1e).

case_images: Case 2. (a) Appearance of the intrascrotal tumor: The masses were located in the midline of the scrotum and independent of the testes. (b) MRI: T2-weighted axial (b1) and coronal (b2) images. The scrotal portion of the tumor was spherical and the dorsal portion was rod-shaped with penetration of the right penile corpora cavernosa. White arrow: tumor; black arrow: penile corpora cavernosa. (c) Operative findings: The thin rod-shaped part of the tumor penetrated the right penile corpora cavernosa. White arrow: tumor; black arrow: penile corpora cavernosa. (d) Excised specimen: The tumor consisted of spherical and rod-shaped parts that were completely removed as one unit. Black line: 10 mm. (e) Histopathological examination: The cyst walls were lined with stratified squamous epithelium without malignant changes. Hematoxylin and eosin (H&E) staining; magnification x100.

case_images: A 6-year-old boy presented to our hospital with a painless tumor in the scrotum, without any other symptoms (Fig. 2a). MRI examination revealed a tumor with a cystic spherical ventral part and rod-shaped dorsal part which penetrated the right penile corpora cavernosa (Fig. 2b1,b2). Bleeding from the corpora cavernosum stopped spontaneously (Fig. 2c). Finally, the spherical body of the tumor was detached without difficulty and the tumor was completely resected (Fig. 2d). Pathological examination confirmed the diagnosis of an epidermoid cyst, just as in Case 1 (Fig. 2e).
