Introduction:
Sacrococcygeal Teratoma (SCT) is a rare benign neoplasm comprised of mixed elements derived from two or more germ cell layers. They are extremely rare in adults. They attract attention because of their gross appearance and bizarre histology.
Presentation of case:
A 25 year old male presented to Surgical OPD, Government General Hospital, Guntur Medical College, Guntur with a large mass comprising a partially developed 3rd leg and rudimentary external genitalia in the lower back. He complained of cosmetic blemish, difficulty in sitting, sleeping and walking.
Discussion:
He was diagnosed mature Sacrococcygeal Teratoma Altman Type II based on history, clinical examination, ultrasound, MRI. Histopathology confirmed the diagnosis. He had complete surgical excision with primary wound closure and a good postoperative recovery. A 3-year follow-up using clinical, biochemical and radiological assessment revealed no evidence of recurrence.
Conclusion:
Mature SCT, though very rare in adults, are usually benign. Complete surgical excision remains the mainstay of treatment.
