Testicular Dermoid Cyst in a 10-Year-Old Child: Case Report and Discussion of Etiopathogenesis, Diagnosis, and Treatment

Abstract

The case of testicular dermoid cyst in a 10-year-old boy who presented for evaluation of a presumed testicular neoplasm is reported. The dermoid cyst was confirmed histologically on frozen section and local excision was performed. Only 5 cases of testicular dermoid cysts in children have been reported so far. We discuss the etiopathogenesis, diagnosis, and treatment.

Testicular and paratesticular tumors and tumor-like lesions in the first 2 decades

“…Individual case reports have been described in patients who were 5, 9, and 10 years old, [80][81][82] and additional examples have been included in studies of testicular tumors in children. 83,84 Among 10 dermoid cysts in a study, five occurred in adolescents 14-17 years old.…”

Leydig Cell Tumor–Comparison of Results of Radical and Testis-Sparing Surgery in a Single Center

“…Between 1969 and 1995, 491 patients with testicular germ cell tumor were treated at our center (54% seminoma, 46% nonseminona; mean age of onset 42.8 years) [1], Thirty-one patients were treated for nonmalignant testicular tumors, in 1 complex case, a paratesticular epidermoid cyst that could not be separated from the tes tis and concomitant dermoid cyst of the spermatic cord was detected [2]: 10 patients were diagnosed to suffer from testicular epidermoid cyst [3], 1 patient had testicu lar dermoid cyst [4], 5 had granulomatous orchitis [5] and 15 had Leydig cell tumors.…”

Case series: Adult testicular dermoid tumours – mature teratoma or pre-pubertal teratoma?

“…Their classification has proved controversial, however they are generally regarded as a specialised group of mature teratoma that, in addition to a keratin-filled, stratified squamous epithelial-lined cysts including skin adnexae in the wall, may contain additional elements [4]. Some authors favour a more stringent definition of dermoid cysts in this setting that allows only adnexal structures within the wall [10]. This type of lesion, whether it contains additional elements or not, is considered to be benign with no documented cases of metastasis in the small number of cases reported [4].…”
