Juvenile Granulosa Cell Ovarian Tumour- Case Study with Radio-pathological Correlation
摘要
Sex cord stromal tumour (SCST) is a less common ovarian neoplasm constituting around 8% of all ovarian malignancies. The commonest SCST is granulosa cell tumor. The adult subtype constitutes the majority (95%) cases in contrast to the juvenile subtype seen in only 5% of granulosa cell tumors.
Case presentationThe following report is of a juvenile granulosa cell tumor (JGCT) in a 20 years old unmarried lady, who complained of pain abdomen and irregular menstruation with passage of clots and dysmenorrhea for 2 months. Ultrasound pelvis showed enlarged right ovary with increased vascularity, possibly secondary to torsion -detorsion sequence. The relevant tumor markers, Prolactin and Beta HCG were within normal limits. MRI pelvis showed a heterogeneously enhancing solid lesion with necrotic and hemorrhagic areas in right ovary, likely suggestive of germ cell tumor. Surgical intervention, right salpingo-oophorectomy was done and ovarian mass of ~ 6 × 5 × 4 cm was resected. HPE showed features suggestive of malignant ovarian neoplasm with differentials of SCST/ germ cell tumor. IHC showed features suggestive of JGCT.
ConclusionJGCT has nonspecific radiological features and prognosis corelates with the stage of the tumor at diagnosis which emphasizes the need for an early diagnosis.
