Testicular epidermoid cyst

Monodermal teratoma: Three case reports and review of literature

BACKGROUND

The incidence of monodermal teratomas of the reproductive system is low, and most doctors lack adequate understanding, which can easily lead to missed diagnoses and/or misdiagnosis. Therefore, it is important to fully understand the clinical characteristics, diagnosis, differential diagnosis, and treatment of monodermal teratomas of the reproductive system.

CASE SUMMARY

Case 1: A 14-year-old boy was admitted to the hospital with a right testicular mass for 1 wk and underwent surgical resection. He was finally diagnosed with right testicular monodermal teratoma with no special postoperative discomfort. Case 2: A 40-year-old woman was admitted to the hospital for uterine abnormalities indicated by ultrasound 20 d prior and underwent laparoscopic surgery. She was finally diagnosed with a left ovarian monodermal teratoma with a satisfactory postoperative quality of life. Case 3: A 49-year-old woman was admitted to the hospital with a pelvic mass that was discovered on B-ultrasound a week prior and underwent laparoscopic resection of the left adnexa. She was finally diagnosed with left ovarian monodermal teratoma, and her postoperative quality of life was satisfactory.

CONCLUSION

Monodermal teratoma is a rare tumor whose clinical manifestations are primarily benign. Simple surgical resection of the tumor is effective.

Multiple scrotal and testicular epidermoid cysts: A rare case report

Epidermoid cysts are benign lesions occurring on the skin usually; however, it rarely occurs in the scrotum or testicular area, and even more rarely the association of multiple epidermal cysts on the scrotum and testis. We report a case of multiple epidermal cysts on the scrotum and testis of a 40-year-old man who consulted for scrotal nodules. To our best knowledge, this is the first case to be reported in the literature. In this paper, we will discuss the histogenesis, the ultrasound features, and the complications of scrotal and testicular epidermal cysts.

Testicular Epidermoid Cyst: A Rare Case Report

INTRODUCTION AN IMPORTANCE

Testicular epidermoid cysts (TECs) are rare benign testicular neoplasms. Recently, testicular epidermoid cysts (TECs) are listed as teratoma of prepubertal type, however it is still difficult to differentiate the epidermoid cyst from malign testicular tumor. Therefore, we would like to report testicular epidermoid cyst at our institution.

CASE PRESENTATION

A 67-year-old man from Indonesia, presented with chronical painless mass of testis since one year ago. On physical examination obtained normal penile structure with descended testicles, palpable intrascrotal mass with size of 10 × 7 × 5 cm, firm consistency, immobile, without any tenderness, and no lymphadenophaty in groin. Scrotal USG showed intratesticular mass, homogenous parenchym, showed no vascularization during Doppler examination. Histopathological examination revealed the specimen of right scrotum with size of 12.5 cm × 8.5 cm × 6.1 cm with red-brownish colored, during lamellation, obtained encapsulated mass with size of 12.2 cm × 7.9 cm × 6 cm, hollowed space filled with porridge-like texture with capsule thickness of 0.1-0.3 cm.

CLINICAL DISCUSSION

Epidermoid cysts are benign lesions occurring on the skin usually, however, it rarely occurs in intratesticular area. Most of the cases (60%) presented with the typical onion-ring phenomenon. Histopathological findings commonly revealed typical well-defined cyst lined by a fibrous membrane. No skin appendages are found in the cyst's lumen and no germ cell neoplasm (GCN) is present in the adjacent testicular parenchyma.

CONCLUSION

All testicular masses are considered malignant until proven otherwise. It is necessary to do accurate diagnosis for the prevention of unnecessary radical orchiectomy.

Testis-sparing surgery for testicular tumors in children: a 20 year single center experience and systematic review of the literature

PURPOSE

Although surgical therapy for testicular tumors (TT) is often radical orchidectomy, tumor resection with preservation of healthy testicular parenchyma has been proposed. This study herein reports a 20 year single center experience applying testicular sparing surgery (TSS) as a primary operative strategy in pediatric patients. A systematic literature review summarizes the utility and outcomes of TSS in appropriately selected patients.

METHODS

Pediatric patients with TT who underwent TSS between 1997 and 2018 were studied. TSS was indicated if patients presented evidence of adequately spared healthy testicular parenchyma on preoperative ultrasound and negative serum tumor markers. A systematic review of the literature was also performed.

RESULTS

12 cases met full inclusion criteria with 10 of 12 subjects in the prepubertal age group. Follow-up was 73 months (range 18-278 months). Only a single male patient (GSCCT) presented with early recurrence and orchidectomy was then performed. No cases of postoperative testicular atrophy were identified. Sexual maturation (Tanner stage) expected for age in each patient was documented. Review of the literature identified 34 published studies including 269 patients (94% prepubertal). Pathologic lesions here were mainly mature teratoma(s)-(62%) with a follow-up period of 4 years. Recurrent tumors were observed in only three patients (1.1%) notably two Leydig Cell Tumors and one Teratoma. Testicular atrophy reportedly occurred in only one single case (0.37%).

DISCUSSION

TSS is a feasible alternative to radical orchidectomy in pediatric male patients with localized TT and negative tumor markers. Long term follow-up is essential to monitor testicular growth, puberty with sexual development and psychological male health.

Testicular epidermoid cyst: about a case report and a review of the literature

Background

The testicular epidermoid cyst is an exceptional benign tumor. The presumptive diagnosis is facilitated by the development of medical imaging (echo-Doppler, elastography, contrast-enhanced ultrasound, MRI). The confirmatory diagnosis is histological.

Case presentation

We report the case report of a 37-year-old man who had a history of repetitive orchitis. He had complained of right scrotal discomfort for 6 months with no associated urinary symptoms. We performed an extemporaneous biopsy given the uncertain diagnosis (Fig. 3), and the histological examination was in favor of a mature teratoma. This prompted us to perform a right orchidectomy. The postoperative was simple. The final histological examination tipped in favor of an epidermoid cyst of the testicle. The patient was seen again at one month, and his clinical examination was normal.

Conclusion

The testicular epidermal cyst is a rare benign tumor of the testicle. Currently, conservative surgery has become the gold standard thanks to the development of medical imaging to differentiate between the both forms of TEC, and it retains certain limits which lie in the differential diagnosis with the teratoma requiring large multicenter studies to better characterize these two entities.

A rare case of epidermoid cyst in urinary bladder

Epidermoid cyst in urinary bladder is a rare pathology with only one known case published prior to this study. In this article, we described imaging findings of epidermoid cyst in the urinary bladder and other parts of urogenital system. Plain CT KUB was performed on Multidetector 16 slice computed tomography scanner-GE Bright speed Elite and plain magnetic resonance imaging on 1.5 T Siemens Magnetom Avanto.

Testicular epidermoid cyst: A rare case

Testicular epidermoid cysts are a rare cause of testicular pathology. No cases of recurrence or metastasis have been reported in the literature. As a result, inguinal partial orchiectomy with frozen section has recently become standard treatment. A 43-year-old male presented with right testicular discomfort and the presence of mass. Right inguinal partial orchiectomy with frozen section was performed, and the right testicle was preserved. The final pathology report confirmed the diagnosis of an epidermoid cyst. The importance of accurate diagnosis of this benign lesion is crucial for the prevention of unnecessary radical orchiectomy.
