Abstract
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.

Core Tip: Monodermal teratomas are rare tumors characterized by their organizational structure originating from a single germ layer-the endoderm, mesoderm, or ectoderm. This teratoma is most commonly found in the ovaries, followed by the testes. Case reports and case series on monoblastic teratoma have been relatively sparse in the published literature. The diagnosis and treatment of two cases of ovarian monoblastic teratoma and one case of testicular monoblastic teratoma are reported in this paper, and their clinical characteristics are described in combination with a brief literature review to deepen the understanding of this disease.
