  • Giant Paratubal Cyst Presenting As Adnexal Torsion: a Case Report
    Publication . Alpendre, F; Pedrosa, I; Silva, R; Batista, S; Tapadinhas, P
    Background: Paraovarian/paratubal cysts constitute about 10% of adnexal masses and are usually small and asymptomatic. A huge paratubal cyst complicated by adnexal torsion is a rare cause of acute low abdominal pain. Case report: We report the case of an obese 31-year-old nulliparous woman who presented with a large pelvic cyst causing ovarian torsion. The size of the mass (~25 cm) caused pain, and obesity led to explorative laparotomy, which showed a huge central abdominal-pelvic cyst arising from the right adnexa. Cystectomy was technically impossible, so all the adnexa was removed. Pathologic diagnosis revealed a papillary serous cystadenoma with torsion of all structures. Conclusion: A giant paratubal cystadenoma is a rare condition and management is challenging. If there are clinical and imaging signs of torsion, it should be approached like any other adnexal mass and surgery should be urgent in order to avoid irremediable compromise of ovarian function.

  • Mesonephric Hyperplasia can Cause Abnormal Papanicolaou Smears: A Case Report
    Publication . Pedrosa, I; Alpendre, F; Sousa, R; Raposo Dinis, S; Figueiredo, P
    Mesonephric hyperplasia (MH) is a very rare condition. There are few cases in the literature. Mesonephric remnants (MR) or MH can be a rare source of abnormal Papanicolaou smears. The most common, often difficult, in the differential diagnosis of MH is mesonephric carcinoma that has a poor prognosis. We report a case of a 29-years-old with a routine Papanicolaou smear reported as atypical glandular cells. The patient underwent to a loop electrosurgical excision procedure and because it is a benign condition and a strong desire to preserve fertility, we opted for clinical surveillance.

  • Rare Case of Sarcomatoid Squamous Cell Carcinoma Arising in an Ovarian Mature Teratoma
    Publication . Sousa Pedrosa, I; Alpendre, F; Sousa, R; Raposo Dinis, S; Gomes, D
    Although mature cystic teratoma (MCT) is benign, malignant transformation (MT) occurs in ∼ 1% to 2% of all cases, and usually consists of squamous cell carcinoma (SCC), which accounts for ∼ 80% of the cases. Spindle-cell (sarcomatoid) carcinoma (SCSC) is an uncommon type of SCC, comprising up to 3% of all cases. The lack of characteristic symptoms and specific imaging findings may lead to preoperative misdiagnosis. Moreover, the clinicopathologic characteristics, the treatment, the prognostic factors and the mechanism of MT have not yet been well understood due to the rarity of such tumors, especially in women of reproductive age. The authors present a case of a 34-year-old patient with 14 weeks of gestation who was diagnosed with an adnexal mass suggestive of ovarian teratoma. A laparoscopy salpingo-oophorectomy was performed after 6 months of delivery, and the histological exam revealed a sarcomatoid SCC in the MCT.
