SURGICALLY TREATED ADNEXAL MASSES IN INFANCY, CHILDHOOD, AND ADOLESCENCE

OBJECTIVE: We retrospectively evaluated the clinical presentation and histopathologic findings of benign and malignant adnexal masses in inf ants, children, and adolescents. STUDY DESIGN: Between 1955 and 1992, 486 patients (aged 7 days through 20 years) with adnexal masses were s urgically evaluated. RESULTS: Of 521 adnexal masses, 92% were benign, including 335 nonneoplastic and 144 of 186 (77%) neoplastic lesions. T he frequency of ovarian malignancies correlated inversely with patient age. Germ cell, stromal, and epithelial malignancies accounted for 40 %, 21%, and 33%, respectively, of the 42 cancers. Nonconcordance betwe en preoperative and postoperative diagnoses was noted in 94 cases. The most common preoperative diagnosis necessitating reassignment was acu te appendicitis. During the last decade of this study, ultrasonography and computed tomography missed no malignancies. CONCLUSION: Physician s who care for young girls must be familiar with the differential diag nosis of adnexal masses to advise conservative management when appropr iate and surgical intervention when necessary.
