Two dermoid cysts developing in an accessory ovary and an eutopic ovary

Area of Science:

• Gynecologic Oncology
• Reproductive Medicine
• Developmental Biology

Background:

• Accessory ovaries are rare congenital anomalies, often associated with genitourinary malformations.
• Tumors originating in accessory ovarian tissue are exceptionally uncommon.
• The embryogenesis of accessory ovaries may involve the separation of migrating ovarian tissue.

Observation:

• A unique case involving concurrent development of two dermoid cysts is presented.
• One cyst was located in an accessory ovary within the left infundibulopelvic ligament.
• The second cyst was found in the ipsilateral eutopic ovary.

Findings:

• This represents the first reported instance of simultaneous dermoid cysts in both an accessory and a normal ovary.
• The concurrent occurrence suggests potential shared etiological factors or a predisposition in cases with accessory ovaries.
• The case underscores the importance of thorough examination in diagnosing rare gynecologic conditions.

Implications:

• This case expands the understanding of rare gynecologic tumors and accessory ovary pathology.
• It may prompt further investigation into the oncogenesis of ovarian masses in the presence of accessory ovaries.
• Clinicians should consider accessory ovaries in the differential diagnosis of adnexal masses, especially when associated with congenital anomalies.
