Mature cystic teratoma of ovary with squamous cell carcinoma arising from it

Squamous cell carcinoma of the ovary arising from a mature cystic teratoma associated with hypercalcaemia

We present a rare case of a 40-year-old nulliparous lady, with no past medical or surgical history, who was diagnosed with metastatic squamous cell carcinoma of the right ovary that originated from a mature cystic ovarian teratoma. Our patient underwent debulking total abdominal hysterectomy, bilateral salpingo-oophorectomy and partial omentectomy followed by postoperative carboplatin and paclitaxel chemotherapy. Rapid disease progression ensued, complicated by severe parathyroid hormone-related protein-induced hypercalcaemia resistant to medical therapy. The patient was treated in a palliative manner and died five months after her diagnosis.

A rare case of squamous cell carcinoma associated with a huge ovarian dermoid cyst in a postmenopausal woman

Malignant transformation of mature cystic teratoma (MCT) is a well-known but uncommon phenomenon seen mostly in postmenopause women. We report a case of a 65-year-old postmenopausal woman with a malignant transformation of MCT and with a low-grade squamous intraepithelial lesion in her cervix. She was treated surgically by total abdominal hysterectomy with bilateral salpingo-oophorectomy with a preoperative diagnosis of right ovarian teratoma. Her postoperative period was uneventful. On follow-up, the histopathology report revealed a right ovarian dermoid cyst with well-differentiated squamous cell carcinoma; there was no evidence of malignancy elsewhere, including the cervix. Ascitic fluid was also free of malignant cells, and the disease was at stage Ia. The patient did not receive any adjuvant chemotherapy and was followed up with clinical examination postoperatively for 1 year, and there was no evidence of any relapse clinically. Preoperative diagnosis of malignant transformation of squamous cell carcinoma (SCC) is difficult, as there is no specific screening marker and no consensus or standard guidelines available regarding the optimum management of this relatively poorly known entity. Here we emphasize the need for a high index of suspicion of malignant transformation with the presence of factors such as elderly age, the huge size of the tumor, and large solid components in the tumor. Considering the scarcity of case reports and studies about SCC arising from MCT, every experience with malignant transformation of MCT should be reported for a better understanding of the disease presentation and management.

Mixed squamous and clear cell ovarian adenocarcinoma arising from endometriosis in a 71 year old patient

•This 71 year old patient was diagnosed with mixed squamous and clear cell ovarian adenocarcinoma.•Patient was surgically staged with guidance from frozen section.•Patient received adjuvant treatment with carboplatin and paclitaxel for 6 cycles.

Incidental diagnosis of squamous cell carcinoma transformation in mature cystic teratoma of the ovary: A case report and review of literature

Malignant transformation in a mature cystic teratoma of the ovary is a rare complication. Herein, we report a case of a 62-year-old woman who was diagnosed with squamous cell carcinoma in a mature cystic teratoma of the ovary in the histopathology examination. This case report highlights the importance of suspecting malignant transformation in an elderly woman with a large mature cystic teratoma of the ovary with a thickened wall so that proper surgical and adjuvant treatments are planned.

A Rare Case of Squamous Cell Carcinoma Arising in Mature Cystic Teratoma

BACKGROUND: Mature cystic teratoma (MCT) is a common benign adnexal tumor contributing to about 20% of all ovarian tumors, and it may occur in 10–20% of women during their lifetime. Although the nature of MCT of the ovary is benign, about 1–2% of MCT undergo malignant transformation. CASE REPORT: Here, we report a rare case of squamous cell carcinoma (SCC) arising in MCT. This one rare case report of SCC arising in MCT showed satisfactory response to adjuvant chemotherapy. Careful routine evaluation is needed for possible recurrency. CONCLUSION: This patient was found with infiltration to the urinary bladder and concluded as stage IIB; therefore, the surgeon decided to give adjuvant chemotherapy with paclitaxel/carboplatin. After given three cycles of paclitaxel carboplatin chemotherapy the patient showed favorable outcome, as the CT scan evaluation showed no residual mass.

Squamous Cell Carcinoma Arising From a Mature Cystic Teratoma of the Ovary: A Case Report

Germ cell tumors represent 20-25% of ovarian tumors, and 95% of them are benign. The most frequent type is the mature benign teratoma (dermoid cysts). The proportion of cases in which malignancy occurs is 0.17-2%. Seventy-five percent to 90% of malignancies are squamous cell carcinomas (SCC).

We present a case of squamous cell carcinoma originating from a mature cystic teratoma that was diagnosed after intraoperative pathology study in a 64-year-old woman who consulted for an adnexal tumor causing abdominal pain. Laparoscopic surgery was scheduled, describing an enlarged right ovary (13 cm) which was included in the ipsilateral broad ligament and adhered to the posterior aspect of the uterus in its distal third as well as the rectum. It was converted to laparotomy and we performed a hysterectomy + double anexectomy + omentectomy + resection of sigma with end-to-end anastomosis after intraoperative pathological study reported for malignancy compatible with squamous cell carcinoma. It was labeled as FIGO III stage. Chemotherapy was decided as adjuvant therapy with carboplatin + paclitaxel (Carbo-Taxol) scheme.

We review the existing literature to provide evidence on a rare pathology with important repercussions for our patients.

Meningioma in mature cystic teratoma of the ovary: clinical and computed tomography findings

Background

Mature cystic teratoma (MCT) with meningioma of the ovary is a very rare benign tumor. There is only 3 reports of this disease until June 2019. The aim of the present study was to describe a ovarian mature cystic teratoma containing meningioma and nests of neuroblasts in a 15-year-old girl.

Methods

The method used in the present study consists of description of the clinical history, image lab features, and pathological result.

Results

The patient complained of a 2-month history of irregular vaginal bleeding. Abdominal computed tomography (CT) showed a large oval cystic-solid mass with septations and fat density shadow, in abdomen pelvic cavity. The cystic part was the main component in the mass. The tumoral solid parts and its internal division could be seen intensified from slight to moderate on contrast-enhanced CT images compared with those on precontrast images, and the solid parts showed heterogeneous enhancement. Neighbouring intestinal tract and the uterus displaced by compression. The pathological examination confirmed the diagnosis.

Conclusions

The clinical feature of ovarian mature cystic teratoma with meningioma includes a lack of specificity. Only meticulous recording of the gross features, histopathological examination including immunohistochemistry and supportive clinical and radiological findings to arrive at a correct diagnosis in case of unconventional tumours. If necessary, preoperative puncture can be performed.

Epidermoid Cysts in a Wandering Spleen: An Unusual Enigma

Epidermoid splenic cysts are rare lesions in the spleen. These cysts are characterized by a stratified squamous epithelial lining, internal septations, and calcification. Congenital in origin, epidermoid splenic cysts are postulated to arise from misfolding and mesothelial cell incorporation into the splenic parenchyma. This report presents a unique case of an 18-year-old woman with an epidermoid splenic cyst in a congenital wandering spleen. Computed tomography and transabdominal ultrasound imaging along with immunochemistry staining confirmed the diagnosis. To the authors' knowledge, this is the first reported case of an epidermoid cyst in a wandering spleen.
