Abstract

Inflammatory myofibroblastic tumour (IMT) of ovary is an uncommon benign neoplasm that can mimic malignancy. It often occurs in children and young adults. Lung is the most common site of IMT.  Precise etiology is not known but recent reports suggested the role of benign reactive process in its pathogenesis.A 32 year old female patient presented to the gynaecology out patient department with complaints of lower abdominal pain and increased frequency of micturition with burning since 15 days. On per abdominal examination, an irregular lump of 18 weeks size with restricted mobility was palpable in suprapubic region. Laboratoratory investigations revealed normocytic normochromic anaemia with neutophilic leucocytosis and raised ESR. Her serum CA 125 levels were slightly raised (44.30 u/ml). Imaging studies showed an infiltrating mass in the pelvis. The patient underwent total abdominal hysterectomy with bilateral salpingo oopherectomy and omentectomy. Histopathological examination of which revealed IMT of right ovary with extension to right  parametrium and adjacent bladder.As IMT is a mimicker of malignancy due to its infiltrative growth. Histopathological examination is mandatory for its diagnosis and treatment. Misdiagnosis can lead to unnecessary extensive debulking surgeries and even chemotherapy. Rarity of this entity in the ovary has made this case worth reporting. DOI: 10.21276/APALM.1285
