Epididymal Lymphangiectasis

Abstract

We report on a 59-year-old man with epididymal lymphangiectasis. The patient had noticed somewhat intermittent intrascrotal painless swelling. The interstitium of the right caput epididymis exhibited a number of large, dilated lymphatic vessels forming irregular channels among and around the epididymal ducts. The afferent epididymal ducts showed dilatation similar to that of the lymphatic vessels except for focal cuboid epithelial linings. Spermatogenesis in the right testis was preserved. Lymphangiectasis in the epididymis is infrequent and needs to be differentiated from other intrascrotal lesions.

Scrotal Cystic Hygroma in a 13-Year-Old Boy

“…When an intrascrotal mass is detected, differential diagnosis is necessary with benign and malignant neoplasms of the testis and its covering tissues, and with other intrascrotal masses such as varicocele, hydrocele, spermatocele and cyst-like lesions [1,8].…”

Perspectives in Pediatric Pathology, Chapter 11. Testicular Pathology of Hamartomatous Origin

“…These dilated vessels compress the efferent ductuli, causing their irregular dilation and distortion. In some cases the malformative or hamartomatous lesions are suspected to be primary tumors, leading to orchidoepididymectomy [69] or only to removal of the vascular lesion [70]. In other cases, the lesion is considered secondary to previous herniorrhaphy, and only epididymectomy is performed [71].…”

Scrotal Lymphangioma in Children

“…The differential diagnosis of intrascrotal lymphangioma includes many diseases [5,6], notably testicular or funicular hydrocele, torsion or primary tumors of the testicle (seminomas or nonseminomas, young tumors of granulosa cells [7] and others), hernia, hematocele, varicocele and epididymal lymphangiectasia [8]. The rarity of the case and its manifestation as a scrotal mass led us to present this case.…”
