Introduction/Background Introduction: Dermoid cysts are benign, complex ovarian tumors composed of various tissues derived from all three germ cell layers. While their occurrence in the ovary is well-documented, their simultaneous presence in the breast during lactation is exceptionally rare. Understanding the clinical and imaging features of such cases is crucial for accurate diagnosis and appropriate management.

Methodology Case Presentation: A 28-year-old lactating female presented with no significant complaints. Routine ultrasonography revealed a 70 x 68 mm dermoid cyst in the left ovary and a solid formation with calcification (15 x 9 mm) in the left breast. Subsequent CT scan confirmed the presence of a dermoid cyst in the left ovary and a suspicious teratoma with a solid component in the left breast, warranting further evaluation for potential malignancy. Notably, the patient exhibited slightly elevated HE-4 levels but remained within the normal range for other tumor markers.

Results Management and Outcome: Considering the complexity of the case, a multidisciplinary team, including gynecologists, oncologists, and radiologists, collaborated to develop a comprehensive management plan. Further investigations, such as biopsies and additional imaging studies, were conducted to determine the nature of the cysts and rule out malignancy. The patient is currently undergoing close monitoring and follow-up examinations to assess any changes in the cysts and ensure timely intervention, if necessary.
