Tarsal tunnel syndrome is defined as a compressive neuropathy of the posterior tibial nerve in the tarsal canal. Schwannoma is a benign tumor that arises from the peripheral nerve sheath. It presents as a discrete, often tender, and palpable nodule associated with neurogenic pain or paresthesia when compressed or traumatized. The growth rate is usually slow, and these lesions seldom exceed 2 cm in diameter. In addition, local recurrence occurs less than 5%. We report on a case of tarsal tunnel syndrome caused by a large recurred space-occupying lesion measuring $4.3{\times}2.7{\times}2.7cm^3$.

데스모이드는 재발빈도가 높은 양성 종양이다. 본 저자들은 흉강 및 복강에 걸쳐 있는 거대한 데스모이드를 충분한 절단면을 확보한 후 절제하고 간좌엽절제술, 좌폐하엽 쐐기절제술, 부분적 심막절제술 후 우심막을 이용하여 심막재건술을 시행하였고 횡격막을 부분 절제한 후 마렉스 메쉬로 횡격막 재건술을 시행하였다.

Peripheral ameloblastoma is an extremely rare odontogenic soft tissue tumor with histologic characteristics similar to those of the intraosseous ameloblastoma. It appears in the gingiva and oral mucosa. And it usually does not show any bone involvement on radiographs, except for saucer shaped erosion of underlying alveolar bone. Recurrence is considered uncommon. We report a case of peripheral ameloblastoma with bone involvement. Histologically it presented with follicles and nest of tumor cells with palisading pattern. And radiographs showed the typical saucer shaped alveolar bone erosion at the distal area of right mandibular third molar. At 6-month follow-up after operation, no local recurrence was noted.

Fibrous histiocytomas are commonly occurred in the skin of the extremeties and rare in the head and neck region. Fibrous histiocytomas in general are considered benign tumors. But deep fibrous histiocytomas have more poor prognosis than cutaneous counterparts and tendency of local invasion and recurrence. Wide surgical excision is the treatment of choice due to high recurrence rate and potential malignancy. We presented a rare case of benign fibrous histiocytoma occurred in the superficial lobe of the right parotid gland, showing palpable mass with pain.

Purpose: Clear cell hidradenoma, now regarded as an eccrine sweat gland tumor on the basis of its enzyme histochemical and electron microscopic features, occurs as a solitary tumor in most instances. Methods: A 17 year old male presented with asymptomatic nodule, which had developed on nipple with a four years of history and total excision and purse-string suture was then performed. Results: No recurrence was observed 2 months after excision. Histologically, it showed a well circumscribed tumor composed of characteristic clear epithelial cells which are focally arranged in glandular patterns. Conclusion: This case is unique in that the tumor developed on the young male nipple, unusual site and this report emphasizes the benefit of local excision to prevent recurrence of these tumor.

Giant cell tumor (GCT) of the spine is a rare benign tumor, but can be aggressive and can exhibit a high local recurrence rate. Furthermore, GCT of the upper thoracic spine may pose diagnostic and management difficulties. Here, we report a rare case of GCT of the upper thoracic spine with soft tissue extension to the spinal canal. The patient was managed by decompressive laminectomy and posterolateral fusion followed by an injection of polymethylmethacrylate into the vertebral lesion. The patient recovered clinically and showed radiological improvement after surgical treatment without tumor recurrence at his last follow-up of postoperative 7 years. We present this unusual case of GCT and include a review of the literature.

Granular cell tumor is an uncommon neoplasm that can occur everywhere in the human body. Granular cell tumor of the cervical esophagus is rare. Histopathologically, granular cell tumor consists of large polygonal cells with small dark nuclei and abundant, fine, granular eosinophilic cytoplasm that show positive immunohistochemical staining using S-100 protein. Surgical excision is the treatment of choice for granular cell tumor. Recurrence is rare, but inadequate resection of granular cell tumor may cause local recurrence. We have experienced one case of granular cell tumor of the cervical esophagus that was misdiagnosed with parathyroid tumor. Therefore, we report it with the literature review.

Primary malignant fibrous histiocytoma (MFH) of the chest wall is extremely rare and is characterized by aggressive features, including a high incidence of local recurrence and distant metastasis. Surgical resection of the chest wall is the primary modality of management. However, surgical treatment is not generally recommended in patients with evidence of distant metastasis. Here, we present a case of chest wall MFH along with a schwannoma mimicking distant metastasis in the right upper arm. The patient was treated by radical en bloc resection and survived for more than 9 years without recurrence.

Trichofolliculoma (TF) is a follicular hamartoma in which hairs protruding out of single orifice. To the best of my knowledge, only two auricular TF has been reported in the English literature. Moreover, clinically TF have been described to mimic malignancy. I present a case of an adult female with mass at the intertragal notch of the left auricle for several years. The clinical diagnosis was thought to be epidermoid cyst, accessory tragus, and other benign skin adnexal tumor. To prevent recurrence, the wide local excision of the mass was performed. The final diagnosis of TF was made. No recurrence was noted during the follow-up of 1 year. It is important for otologists to be familiar with the clinical and pathologic characterization of TF, to make the correct diagnosis.
