Abstract / Summary
Background: Mature cystic teratomas are some of the most common benign ovarian germ cell tumors and are often discovered incidentally during imaging or surgery. Reports on the gross anatomical relationships for these lesions during body donor dissection are particularly limited. This case study explores an ovarian mass with gross features consistent with a mature cystic teratoma discovered during a routine donor dissection and draws attention to the academic and educational value to be gained from its integration into anatomical instruction. Methods: Routine dissection of an 89-year-old female donor revealed a unilateral, well-encapsulated ovarian mass within the mesosalpinx of the left uterine tube. Gross anatomical relationships to nearby structures were documented photographically. The lesion was measured and examined for distinguishing macroscopic features. Results: The ovarian mass measured approximately 7 × 4 × 5 cm3 and was completely contained within a smooth external capsule. After incision, it was found that the lesion contained profuse sebaceous contents and hair; all findings consistent with a mature cystic teratoma. Direct observation of the mass in situ allowed for analysis of its anatomical relationships with adjacent pelvic organs. This supported assimilation of gross anatomy, embryology, and ovarian pathology during first-year medical education. Conclusions: Discovery of ovarian masses during donor dissection provides a unique opportunity for intact pelvic anatomy education to be integrated with uncommon pathologic findings. Gross documentation of lesions exhibiting characteristics consistent with mature cystic teratomas can enhance anatomical education, while simultaneously contributing a more comprehensive description of these uncommon lesions to the currently limited literature.
