Cystic Dysplasia of the Testis: A Unique Congenital Anomaly Studied by Microdissection

Cystic Dysplasia of the Testis: A Very Rare Paediatric Tumor of the Testis

“…Since the first description of the CDT by Leissing and Oppenheimer [1] in 1973, 30 reports about this rare tumor of the testis have appeared in literature (table 1). Patients with CDT are usually infants or adolescents.…”

“…3, 4). often the cysts termed testicular are actually paratesticular and may owe their pathogenesis to anomalous development of the testicular tunics (hydroceles), the lymphatics or the growth of an epidermal cyst arising in scrotal skin [1]. Other causes of scrotal swelling include torsion of the testis, epididymo-orchitis and post-traumatic hematoma.…”

“…The cephalic portion of the Wolffian duct is an essential evocator of the metanephros. Without its influence upon the metanephrogenetic mass, agenesis results [1]. This phenomenon is exemplified by the well-documented association of ipsilateral renal agenesis and the absence of the vas deferens [13].…”

“…Leissring and Oppenheimer [1] showed by microdissection that the cystic spaces appear to communicate. These findings differ in adults in whom obstruction can be found in over 75% of all cystic masses in the mediastinum testis [14], mostly in the epididymis secondary to inflammation [15].…”

Cystic Rete Testis in a Cat and Fox

“…Papillomas, papillary cystadenoma, papillary carcinomas, and adenocarcinomas of the rete testis have been reported in man [3,4,9,101. Cystic dysplasia localized in the region of the distal seminiferous tubules of the testis has been documented in a boy [ 5 ] , and a congenital testicular cyst (partially lined by cuboidal epithelium) has been reported in an infant [7]. Its origin was believed to be ectopic epithelium.…”
