Neuroendocrine Tumor Arising within Mature Cystic Teratoma of the Pancreas: Literature Review and Case Report

Cystic teratomas are germ cell tumors most commonly found in the ovaries and testes. The pancreas, however, is very rare as a site of occurrence. Moreover, only two cases of cystic teratoma with concomitant neuroendocrine tumor have been reported to date. We report the case of a 33-year-old female who presented with abdominal pain. Computed tomography and magnetic resonance imaging of the upper abdomen revealed an 85 mm cystic tumor in the head of the pancreas. Cystic teratoma and mucinous cystadenoma were suggested as differential diagnoses. Cytopathologic analysis of endoscopic ultrasound-guided fine needle aspiration was consistent with mucinous cystadenoma. Therefore, the patient underwent surgical resection. Histologic analysis revealed a mature cystic teratoma of the pancreas with a concomitant neuroendocrine tumor. The patient is in great condition at 8 months follow-up. Cystic teratoma of the pancreas with a concomitant neuroendocrine tumor is an extremely rare condition. Surgical resection remains the mainstay of treatment as it provides a definitive diagnosis and no recurrences have been reported to date.

TERATOME KYSTIQUE DU PANCREAS CHEZ UNE FILLE DE 14 ANS AU CHU KARA (TOGO)

Objective: We report a case of cystic teratoma of the pancreas in a young girl. Observations: Its concerns a young girl aged 14 years old, admitted to the paediatric emergency department of University teaching hospital of Kara (Togo). She presented with nonspecific acute abdominal pains since two days. Physical exam was poor. Ultrasound and Computed tomography (CT) imaging of the abdomen demonstrated a cystic lesion arising from the pancreatic tail. She was operated in emergency. A simple cystectomy was performed. Pathological evaluation confirmed a benign teratoma (dermoid cyst). The postoperative period was uneventful. Conclusion: Cystic teratomas of the pancreas are rare. Their symptoms have no particularity and the diagnosis is rarely made in preoperative. Their treatment is surgical because of the risk of complications.

Coincidence of Mature Cystic Teratoma and Serotonin-producing Neuroendocrine Tumor of the Ileum

Mature cystic teratomas are often found in gonadal sites, but are very rarely located extragonadally, for example, in retroperitoneum, mediastinum, central nervous system, lung, or liver. In the literature, only 10 cases of cystic teratoma originating from the diaphragm have been reported. Here, we report for the first time a metachronous occurrence of a benign mature cystic teratoma in the left diaphragm together with a serotonin-producing neuroendocrine tumor of the ileum. The 51-year-old, female patient received a partial resection of the ileum due to a neuroendocrine tumor (pT3N1M0) 4 years ago. Furthermore, she was operated for a benign cystadenoma of the right ovary 3 years ago. In her past medical history, she had an appendectomy in her childhood and a subtotal thyroidectomy 10 years ago. To our knowledge, this is the first report describing the metachronous occurrence of benign mature cystic teratoma in the diaphragm and a highly differentiated neuroendocrine tumor of the ileum. The possible coincidence of both diseases is discussed.

Cystic teratoma of the diaphragm which mimicked soft tissue lipoma

We report a case of cystic teratoma of the diaphragm that was considered to be a soft tissue lipoma by the preoperative examination. A magnetic resonance imaging revealed an 8 x 8 cm well-demarcated, homogeneous mass. On T1- and T2-weighted imaging, the mass was isointense to fat. On the fat-suppressed imaging, the signal from the mass was reduced to the same degree as subcutaneous fat. We performed marginal excision. The tumor contained a large number of hairs and oily liquid; and it was connected to the diaphragm.

Giant cystic teratoma of the ovary – a case report

A case of a giant mature cystic teratoma of the ovary in a 19-year-old nulliparous girl is reported. She was first suspected to have a liver pathology with gross ascites until ultrasound scan showed a multicystic ovarian tumour. There were no constitutional symptoms. Laparotomy and oophorectomy yielded satisfactory results. Histology confirmed a benign cystic teratoma of the ovary. This case demonstrates that dermoid cysts can grow to enormous sizes weighing over 20kg and should be considered whenever gross abdominal distension is seen in women of reproductive age. To the best of our knowledge, this is the first reported case of cystic teratomas of such massive size.

“Primary” Benign Retroperitoneal and Intraspinal Dumbbell-Shaped Cystic Teratoma

A case of unusual dumbbell-shaped cystic teratoma is presented. To investigate and describe an unusual case of retroperitoneal cystic teratoma with spinal invasion in an adult. The image findings, minimally invasive surgical procedures, and clinical outcome were discussed, and the literature was reviewed. Primary benign cystic teratomas of the retroperitoneum are rare. Extension of these lesions into the spinal canal is more rare. In this report, by presenting a case of cystic teratoma with such extension, the origin of the tumor, and the value of computerized tomography and magnetic resonance imaging (MRI) in the preoperative diagnosis and surgical approach for the extended lesion are discussed. The patient was a 24-year-old female who had had low back pain with bilateral sciatica for 2 months. Preoperative computerized tomography and MRI of the thoracic and lumbar spines showed a dumbbell-shaped tumor, with the solid part residing in the right retroperitoneum near the neuroforamen of the L2-L3 spines and the cystic part extending into the spinal canal. By performing right L2-L4 hemilaminectomies with a mini retroperitoneal approach, the tumor was removed en bloc in one stage. Diagnosis of cystic teratoma was confirmed by pathologic examination. The patient recovered well without any neurologic deficits, and recurrence of tumor has not been found for 9 years postoperatively. Total surgical removal of tumor is an ideal treatment for retroperitoneal and intraspinal dumbbell-shaped cystic teratoma. MRI displays the precise location, morphology, and adjacent structures of the tumor, which provide for better preoperative planning and more complete removal of tumor with less neurologic damage.
