Aggressive angiomyxoma of the epididymis: A case report

Figure 1 Computed tomography and colour Doppler ultrasonography (testes, epididymis and spermatic cord). A: The computed tomography showed a cystic lesion in the left scrotum measuring about 6.6 cm × 5.5 cm with clear borders (orange arrow), and the left testicle was normal in size (white arrow); B: Ultrasound showed that the left testicle size was 4.3 cm × 2.8 cm × 2.6 cm (white arrow). On the left side of the scrotum there was a well-defined hypoechoic mass (orange arrow) with regular morphology and heterogeneous internal echogenicity.

Figure 2 Micropathological image of an epididymal mucocele in this case. A: Dilated, thick-walled, hyalinised blood vessels of variable size are seen microscopically (orange arrow); B: Clostridial and astrocytic tumour cells (orange arrow) were scattered in the mucus stroma with no evident heterogeneity. Original magnification of × 200.

Figure 3 Gross pathological picture of this case of epididymal mucinous neoplasm. A: The visible mass is an enveloped, white, grey, well-confined solid tumour (7.0 cm × 6.0 cm); B: A gel-like cut of the mass can be seen (orange arrow).
