A case benign struma ovarii

Struma ovarii is a rare ovarian tumor and a monodermal variant of dermoid tumors of the ovary in which thyroid tissue components constitute more than 50% of the mass. Struma ovarii accounts for 0.5–1.0% of all ovarian tumors and 2-5% of ovarian teratomas. Most cases are benign, but malignant transformation is found in a small percentage. It usually presents as a unilateral adnexal mass at fifth and sixth decades of life, with symptoms like other ovarian tumors. The definitive diagnosis is made by histological examination. Adnexectomy remains the standard line of treatment for benign disease. A 41-year-old lady presented with pain in abdomen for 3 months. On ultrasonography and MRI, a multiloculated solid cystic lesion of 7×6 cm with internal echoes was found in the right adnexa. Laparoscopic right adnexectomy was performed. Histopathology was consistent with struma ovarii. Due to its vague clinical manifestations and diverse imaging characteristics, pre-operative diagnosis is challenging.

A rare case of primary fallopian tube carcinoma in a woman with post-menopausal bleeding

Primary fallopian tube carcinoma (PFTC) is a rare tumor accounting for about 0.5% of all gynecological cancers. The rarity of the tumor with its non-specific clinical presentation and radiological findings lead to a low suspicion of PFTC by the attending clinician. We present a case of this tumor in a 62 years post-menopausal parous woman who presented with intermittent vaginal bleeding with normal clinical examination and an adnexal mass on USG and MRI. She underwent laparosopic total hysterectomy with bilateral salpingo-oophorectomy, infracolic omentectomy and staging biopsies followed by adjuvant chemotherapy. Primary fallopian tube carcinoma should be considered in the differential diagnosis of peri and postmenopausal women who present with an adnexal mass, unexplained bleeding per vaginum, pelvic pain, or a cervical smear with abnormal glandular cells. The treatment is similar to epithelial ovarian carcinoma, which includes total hysterectomy with bilateral salpingo-oophorectomy and comprehensive surgical staging
