Cervical teratomas: an analysis. Literature review and proposed classification

Cervical teratomas are uncommon lesions usually diagnosed at birth but occasionally reported in older children and adults. During a 58-year span, nine cervical teratomas were identified at our institution (four previously reported): three stillborns with giant tumors; five live newborns; and one adult with a malignant tumor. Of the five newborns, two prematures died within one hour of birth. Of the three survivors, 2 had respiratory distress at birth. These infants were treated with early excision and are well at 7, 6, and 2 years of age. The last patient also had cystic fibrosis. The adult died of metastatic disease 8 months after resection. A literature review disclosed 212 cases in addition to the five reported here. Previous attempts at categorizing cervical teratomas have failed to address clinical patterns and have little prognostic value. We propose a classification based on birth status, age at diagnosis, and the presence or absence of respiratory distress. Group I--stillborn and moribund live newborns: number (N), 27; mortality (M), 100%. Group II--newborn with respiratory distress: N, 99; M, 43.4%. Group III--newborn without respiratory distress: N, 37; M, 2.7%. Group IV--children age 1 month to 18 years: N, 31; M, 3.2%. Group V--adults: N, 23; M, 43.5%. Twenty-six patients in group II and one in group III died without excision of the mass. Seventy-three patients in group II, 36 in group III, and 31 in group IV had extirpation of the tumor. Operative mortality was 11%, 0%, and 3.2%, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)
