Paratubal Atypical Proliferative Serous Tumour in a Young Adolescent Female - A Diagnostic Dilemma

Abstract

Introdcution: Paratubal atypical proliferative serous tumours are rare usually arising from the mesothelium or from the remnants of mesonephric and paramesonephric ducts. We present a rare case of paratubal borderline serous tumour in a young adolescent female presenting clinically as an omental cyst.Case Report: A 14-year old unmarried female presented with abdominal pain in right iliac fossa. MRI revealed a well demarcated space occupying lesion in the pelvis almost in midline measuring 12x11x8cm. Lesion was abutting and displacing overlying bowel loops with likely adhesions suggestive of complex omental cyst. The patient underwent cystectomy. The final histopathologic report confirmed the cyst as Paratubal atypical proliferative serous tumour. Conclusion:We experience a rare case of atypical proliferative serous tumour of paratubal origin. The patient was youngest than any of the other cases reported in the literature. Fertility sparing surgery should be considered as a standard treatment of borderline paratubal tumour, if patient desires future fertility.
