We report here a case of synchronous dermoid cyst with secondary malignant tumor and uterine endometrial adenocarcinoma that responded to UFT. A 35-year-old female complained of abdominal fullness and visited our hospital. She had an abdominal mass which was newborn-head size. We performed right salpingo-oophorectomy and partial omentectomy. The pathological findings were dermoid cyst with secondary malignant transformation. After the operation she had underwent cyclic chemotherapy with CDDP, CPA, THP and 5-FU. After three cycles of chemotherapy, a uterine recurrence was suspected from her uterine endocervical smear test. Then we performed a second operation, but radical surgery was impossible due to the presence of multiple metastases to pelvic lymph nodes. The pathological findings were primary uterine endometrial adenocarcinoma, not metastasis from dermoid cyst with secondary malignant tumor. After the second operation, she was treated with oral UFT (400 mg/day), as she refused chemotherapy and radiotherapy. Two months after the start of UFT, the tumor markers were reduced remarkably, and the patient maintained good QOL throughout the treatment without serious adverse events. We conclude that UFT might be benefical in the treatment of advanced gynecologic cancer.

A 54-year-old woman complained of abdominal pain and watery diarrhea that had begun two days before admission. Physical examination revealed abdominal distention and tenderness throughout the abdomen, but there was no muscle guarding or rebound tenderness. The leukocyte count was 27.0 x 10(3)/microl, and CRP was 28.5 mg/dl. A plain film of the abdomen revealed the shadow of a huge gas-containing mass with an air-fluid level and a dilated small intestine with air-fluid level. CT showed a huge gas-containing cystic mass with fatty component and solid structure. Omental thickening was also noted. Emergency surgery was performed, and an enlarged left ovary that was adherent to the small intestine was removed. Microscopic examination revealed a squamous cell carcinoma in the dermoid cyst wall. The carcinoma had directly invaded the small intestine and a fistula between the cyst and the intestine was noted. Thickened omentum showed granulomatous inflammation in the fatty tissue, but no metastases were detected. The histopathological diagnosis was dermoid cyst with malignant transformation and invasion of the small intestine. Chemotherapy was performed, but the patient died of progression of peritoneal metastases 10 months after the operation.

Metastatic spread to the intestines by squamous cell carcinoma (SCC) arising in mature cystic teratoma (MCT) or dermoid cyst is a very rare event. A case of a 40-year-old cachectic woman is presented with an MCT of the left ovary found at autopsy. Focal mural thickening of the cyst wall harbored a moderately differentiated SCC with single cell keratinization. Intramural metastases were noted in the jejunum, ileum, colon transversum, and left colonic flexure. In addition, liver metastases were detected. The tumor was staged as FIGO IV. The peritoneum was covered diffusely by fibrinous and suppurative exudate. In this unusual case, metastasizing SCC of the ovary arising in an MCT led to suppurative peritonitis and consequently to death of the patient. Follow-up procedures regarding intestinal spread could be useful in patients with SCC in MCT.

The purpose of the article is to review the CT and MR imaging features of orbital tumors in children. Tumors in children are usually different than those in adults. Clinical symptoms are usually non-specific. Clinical examination combined with US may be sufficient for diagnosis and follow-up of benign and superficial lesions. CT and/or MRI are needed for deep or malignant lesions. CT is valuable for osseous and/or calcified lesions. MR is advantageous because of its superior spatial resolution and non-ionizing nature. Malignant tumors correspond to about 20% of lesions and include primary tumors (retinoblastoma, rhabdomyosarcoma) and metastases. Benign pathology is more frequent (80%) with dermoid cyst corresponding to about 50% of orbital masses.

Advances in imaging techniques over the past few decades have continued at an astounding pace and now physicians have various modalities to examine the human body. These imaging techniques may be used to assist in diagnosis, staging, and follow-up of oncology patients. The increasing complexity of diagnostic radiology provides a challenge to radiologists and oncologists to use these tools in a clinically efficient and cost-effective manner. The ultimate goal is to offer a safe and effective examination that provides clinically relevant information for the management of an individual patient. Currently ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) are being used to evaluate patients with gynecological malignancies. Goal of this review is to provide an overview of clinically available imaging techniques and discuss relative strengths and weaknesses. This article summarizes the diagnostic performance (sensitivity, specificity, positive and negative likelihood ratios) of US, CT, MRI and PET/CT in the diagnosis of various gynecological diseases and tumors. US is the first-line imaging modality of choice and is used to discriminate between benign and malignant adnexal masses and for characterizing adnexal tumors such as dermoid cyst, endometrioma, hemorrhagic corpus luteum, etc., for diagnosing intrauterine pathology in women with dysfunctional uterine bleeding, and for confirming or refuting pelvic pathology in women with pelvic pain. MRI can play a role in detecting the extent of disease and helps in local staging of gynecologic tumors. CT can be used to detect extrapelvic disease and PET/CT can assist in detecting distant metastatic disease in order to select appropriate surgical candidates.

Testicular carcinoid tumors are rare with only limited studies. We identified 29 primary testicular carcinoid cases from 7 academic institutions. Patients ranged in age from 12 to 65 years old (mean 36). The most common presenting symptom was the sole finding of either a testicular mass or swelling seen in 15/24 cases with available information. The next most common mode of presentation was as an incidental finding seen in 6 cases. Two patients had carcinoid syndrome including diarrhea, hot flashes, and palpitations. Nineteen were pure carcinoid tumors, 3 were associated with cystic teratoma, 2 with cysts lacking epithelial lining, 4 with epidermoid cyst, and 1 with dermoid cyst. The mean size was 2.5 cm. All 29 primary carcinoids lacked associated intratubular germ cell neoplasia, unclassified type. Mitotic figures were rare in primary carcinoid tumors with only 3 cases showing more than 2 per 10 HPF; necrosis was found in only 1 case. Random scattered mild to moderate nuclear atypia was seen in 12/29 cases. Of the 28 cases found premortem, treatment included focal excision in 3 patients and radical orchiectomy in 25 patients. Follow-up, available in 24 cases, ranged from 1 to 228 months (mean 52.7 mo); of the 20 patients with testicular typical carcinoid tumors found premortem, all were alive at last follow-up without recurrences or metastases. Of the 4 patients with a primary atypical carcinoid tumor, 1 at the time of diagnosis had retroperitoneal and lung metastases who after chemotherapy underwent resection of the retroperitoneal tumor showing metastatic yolk sac tumor and embryonal carcinoma. After resection, serum AFP levels remained elevated and the patient is scheduled for salvage chemotherapy and bone marrow transplant. The other 2 patients with atypical carcinoid and follow-up had no evidence of disease at 68 and 114 months. Most primary carcinoid tumors of the testis have a benign clinical course even if associated with epidermoid/dermoid cysts, or histologically mature teratoma. However, lesions with the morphology of atypical carcinoid can occasionally exhibit metastatic spread.

This educational paper reviews the normal anatomy of the cavernous sinus (CS) and the imaging findings of common and uncommon lesions of this region. CS lesions may arise from different components of the CS or from adjacent structures and spaces. They can be classified as tumoral, inflammatory/infectious, vascular and congenital. Tumoral lesions include benign (meningiomas, pituitary adenomas, schwannomas) and malignant neoplasms (chondrosarcomas, chordomas, nasopharyngeal carcinomas, leukemia, metastases). Inflammatory/infectious conditions comprise: Tolosa Hunt, abscess, Lemierre syndrome and thrombophlebitis. Vascular lesions include: hemangiomas, carotido-cavernous fistula, aneurysms, arteriovenous malformations. Congenital conditions include the epidermoid cyst, dermoid cyst and fatty deposits. Although imaging features of non-vascular CS diseases are most often non-specific, careful analysis of the adjacent structures suggests the correct diagnosis. In vascular pathology, characteristic MR imaging findings are observed.

In patients affected by differentiated thyroid cancer, the whole-body scan (WBS) with 131-radioiodine, especially when performed after a therapeutic activity of 131I, represents a sensitive procedure for detecting thyroid remnant and/or metastatic disease. Nevertheless, a wide spectrum of potentially pitfalls has been reported. Herein we describe a 63-year-old woman affected by follicular thyroid cancer, who was accidentally found to have an abdominal mass at post-dose WBS (pWBS). pWBS showed abnormal radioiodine uptake in the upper mediastinum, consistent with lymph-node metastases, and a slight radioiodine uptake in an abdominal focal area. Computed tomography revealed an inhomogeneous mass in the pelvis, previously unrecognized. The lesion, surgically removed, was found to be a typical dermoid cyst of the ovary, without any evidence of thyroid tissue. By immunohistochemistry, a moderate expression of the sodium-iodine symporter (NIS) was demonstrated in the epithelial cells, suggesting a NIS-dependent uptake of radioiodine by the cyst.

Metastatic primary testicular carcinoid tumor remains a very rare condition. We report the first case of metastatic primary testicular carcinoid tumor where along retroperitoneal lymph node dissection excision of the Inferior Vena Cava was also performed. The rarity is further emphasised by the presence of a contralateral testicular dermoid cyst. Given the features of the tumor were not in keeping with the traditional predictors of metastases (primary tumor >7.3 cm, poor differentiation and the presence of carcinoid syndrome) this case adds valuable addition to the relatively limited literature available on this rare condition.

Mature cystic teratoma (MCT) is the most common germ cell ovarian tumour, which accounts for 15-20% of all ovarian neoplasms. The frequency of MCT cases undergoing malignant transformation ranges from 0.17% to 2%. Our aim for presenting this case is to contribute to formation of an algorithm in the literature for the treatment and follow-up of MCT undergoing malignant transformation. A 38-year-old female patient presented to the emergency service with acute abdomen. The patient underwent salpingo-oophorectomy due to a prediagnosis of ovarian torsion with a dermoid cyst. Postoperative pathological examination reported oncocytic and tall columnar type papillary thyroid carcinoma arising on a mature cystic teratoma. During the follow up no local recurrences or metastases were identified in one-year. The rarity of MCT cases undergoing papillary type thyroid carcinoma transformation hinders the establishment of an algorithm for treatment and follow-up in literature.
