Paraganglioma is a rare tumor of paraganglia, derived from neural crest cells in sympathetic or parasympathetic ganglions. It can be widely distributed from the skull base to the bottom of the pelvis. The pancreas, however, is a rare location of this neoplasm, and only a limited number of cases have been reported in the English literature, especially with gadoxetic-acid-enhanced magnetic resonance imaging (MRI) and diffusion-weighted images (DWI). We herein report a case of pathologically proven paraganglioma in the pancreas head with a literature review on endoscopic ultrasonography (EUS), computed tomography (CT), gadoxetic-acid-enhanced MRI, and DWI sequence.

An ectopic thyroid is caused by abnormalities in migration of the thyroid during development and rarely occurs in the thoracic cavity or the abdominal cavity. We report the case of a 64-year-old female who had abnormal findings from a thyroid hormone test during follow-up after thyroid cancer surgery. Based on the radioisotope diagnostic test, an ectopic thyroid inside the thoracic cavity was suspected. Through surgical treatment, the patient was diagnosed with ectopic intrapulmonary thyroid. Ectopic intrapulmonary thyroid is reported to be very rare and the case is described along with a literature review.

Cowden's disease is a rare autosomal dominant, multiple hamartoma syndrome with characteristic mucocutaneous lesions. It is associated with abnormalities of the breast, thyroid, and gastrointestinal tract; and is characterized by multiple hamartomas in the gastrointestinal tract and mucocutaneous lesions such as trichilemmomas, oral papillomatosis, facial papules, and acral keratosis. A 21-year-old male patient presented with erythematous facial papules, oral mucosal papillomatosis, and punctate palmoplantar hyperkeratosis indicating a definite case of Cowden's disease. This disease derives from variable expression resulting from a mutation in the PTEN gene. Gastrointestinal endoscopy and colonoscopy revealed multiple hamartomas in the stomach and colon. On thyroid ultrasonography, several probable benign nodules were noted in the right thyroid gland. He had no pertinent family history and no other systemic findings. Further regular laboratory and image studies will be planned for our patient, as well as his family members. Sporadic Cowden's disease is rarely observed. Herein, we report a case of Cowden's disease without known family history. Dermatologists should be aware of the possibility of Cowden syndrome based on its several dermatologic findings.

Leiomyosarcoma may occur anywhere in the body but rarely occurs in the heart or great vessels. Leiomyosarcoma may be managed by surgical resection with or without chemotherapy or radiotherapy. Owing to the high rate of metastasis and poor prognosis, a definitive treatment modality for leiomyosarcoma has not yet been suggested. This case study reports the surgical management of the recurrent leiomyosarcoma of the heart and the great vessels in a 63-year-old woman.

Although neoplastic involvement of the pericardium is frequently present postmortem, cardiac manifestations before death are uncommon, and cardiac tamponade as the initial presentation of cancer is rare. We are presenting a metastatic pericardial tumor with cardiac tamponade of unknown primary neoplasm. The patient brought to hospital in a state of unconscious. The chest x-ray film showed cardiomegaly with a globular heart shape and right pleural effusion. We underwent an anterior thoracotomy and pericardial window was created. The histopathologic finding of pericardium, pleural and pericardial effusion show a metastatic adenocarcinoma. The patient subsequently received adjuvent radiotherapy and chemotherapy, but he expired on the postoperative 132 day.

A mucocele is a cystic dilatation of the vermiform appendix that contains mucous material. The symptoms associated with it are not specific and the diagnosis is seldom made prior to surgery. The reported prevalence in appendectomy specimens procured during surgery is 0.2-0.3%. Recently, we experienced a case of patient with appendiceal mucocele detected by colonoscopic examination. This case did not show typical colonoscopic features of a mucocele, demonstrating protrusion of mucin, in the absence of a smooth mound with normal overlying mucosa surrounding the appendiceal orifice. The case involved a 64-year-old woman who underwent a colonoscopy. An abdominopelvic computed tomography scan suggested a normal appendix. Subsequently, we performed an appendectomy. The pathologic finding was a low-grade appendiceal mucinous neoplasm.

Sebaceous carcinoma is a malignant neoplasm that usually arises in the sebaceous glands of the eyelids. Its pathogenesis is unknown; however, irradiation history, immunosuppression, and use of diuretics are known risk factors. The mainstay of treatment for sebaceous carcinoma of the eyelid is wide surgical resection with a safety margin of 5 to 6 mm, which often results in full-thickness defects. The reconstruction of a full-thickness defect of the eyelid should be approached using a three-lamella method: a mucosal component replacing the conjunctiva, a cartilage component for the tarsal plate, and a flap or skin graft for the skin of the eyelid. In this case, a full-thickness defect of the upper eyelid was reconstructed after tumor removal using a combination of a nasal septum chondromucosal composite graft and a forehead transposition flap, also known as a "Fricke flap." The flap was designed to include a line of the eyebrow on the lower margin of the flap to replace the eyelash removed during tumor excision. The wound healed completely, without any early or late complications, and the outcome was satisfactory.

We report a case of primary undifferentiated cardiac sarcoma. The tumor originated from the left atrial free wall with multi-organ metastases, e.g., lung, and adrenal gland. The patient gradually grew worse with dyspnea and hemoptysis because of the obstructed left atrial outflow. Surgical resection of the left atrial sarcoma was undertaken to save the patient's life, followed by chemotherapy and brain irradiation as adjuvant therapy. The prognosis of cardiac sarcoma with metastases is very poor. However, in patients with hemodynamic instability, surgical intervention could be a therapeutic modality as palliation.

The most common primary heart tumor in infants is the rhabdomyoma. It is known that tuberous sclerosis is found in half of the patients with cardiac rhabdomyoma. Because the prognosis of this tumor associated with subaortic stenosis is poor, the surgical intervention is indicated. We report one case of left ventricular rhabdomyoma with tuberous sclerosis.
