A 10-year-old female patient presented with a rapidly growing nodular mass lesion on her right frontal area. On skull radiography and computed tomography (CT) imaging, this mass had a well-demarcated punch-out lesion with a transdiploic, exophytic soft tissue mass nodule on the frontal scalp. Magnetic resonance (MR) imaging revealed the presence of a $1.5{\times}1.2{\times}1$ cm sized calvarial lesion. This lesion was hypointense on T1 and heterogenous hyperintense on T2 weighted MR images, and exhibited heterogeneous enhancement of the soft tissue filling the punch-out lesion after intravenous administration of gadolinium. En block removal of the tumor with resection of the rim of the normal bone was performed. The pathological diagnosis was intravascular papillary endothelial hyperplasia (IPEH). After surgery, no recurrence was found for 8 months. IPEH is a rare and benign reactive lesion usually found in thrombosed subcutaneous blood vessels. Involvement of skull bone is rare. In this article, we present a case of IPEH involving the calvarium, in a 10-year-old woman.

Cementoblastoma is a benign ectomesenchymal odontogenic neoplasm that forms a mass of cementum or cementum-like tissue continuous with the tooth root. Cementoblastoma represents 1% to 6.2% of all odontogenic tumors, and occurs more than 75% arise in the mandible, with most cases arising in the molar and premolar regions. About 75% arises before the age of 30. Radiographically, it appears as a radiopaque mass with a thin radiolucent rim attached to the roots of a tooth. The recurrence rate is 37% in the current study and cortical expansion and perforation of the cortex are common findings in lesions that subsequently recurred. It is apparent that recurrence rate depends largely on the completeness of removal than any other factor. Here we present a 20 year old, female case of an unusual multiple recurrent cementoblastoma around a previous lesion which had been surgically excised 2 years ago.

Osteoma is a slow growing benign osteogenic lesion characterized by proliferation of compact or cancellous bone. Osteomas may be classified as peripheral, central, or extraskeletal. Central osteoma arise from the endosteum, pheripheral osteoma from the periosteum, and extraskeletal soft tissue osteoma within a muscle. Peripheral osteoma of the mandible is uncommon. They manifest as asymptomatic, fixed tumors of bony-hard consistency that may be sessile or pedunculated. Radiographically, a well circumscribed round or oval radiopaque mass is seen. Here, we report a case of a huge solitary peripheral osteoma of the buccal posterior mandible in a 40-year-old woman who was otherwise in good health. The patient visited at the dental clinic because the lesion makes esthetic problem. Treatment was performed by surgical esthetic recontouring and histological examination. The patient remains free of recurrence after surgical esthetic recontouring operation.

Central odontogenic fibroma is an extremely rare benign tumor, accounting for less than 0.1% of all odontogenic tumors. The most recent literature review that only 69 cases have so far been reported. This tumor has a slow persistent growth that results in painless cortical expansion clinically, and well defined unilocular or multilocular radiolucent lesion. Root resorption of associated teeth is common, and lesions located between the teeth often cause root divergence. There is occurring tendency to female more than male, and occurring in the mandible and in the maxilla with equal frequency. The treatment is surgical excision with no tendency to undergo malignant transformation. We report a case of central odontogenic fibroma in the maxilla of a 27-year male with literatures review.

Warthin's tumor is a benign neoplasm that most frequently occurs in the parotid gland. Warthin's tumor shows a tendency of bilateral occurrence, but most of bilateral tumors occur at different time. It usually affects older man and grows slowly. Surgical excision is appropriate treatment for patients with Warthin's tumor and rarely recurs after removal. We report a rare case of bilateral Warthin's tumor which detected at the same time. A 54-year-old man had painless, slowly growing masses on the both mandibular angles. The masses were detected ten years ago. CT scan, ultrasonographic evaluation and fine needle biopsy was performed for preoperative diagnostic study. Superficial parotidectomy was done one after the other at ten-day intervals. After excision, histological examination revealed a mixture of ductal epithelium and a lymphoid stroma. The overlying surface of lymphoid tissue was covered with epithelial cells that was abundant of eosinophilic cytoplasm. Both masses were diagnosed as Warthin's tumor. Postoperatively, the patient did well and had no evidence of recurrence of tumor for 2 years follow-up period. Authors experienced a rare case of bilateral Warthin's tumor which detected at the same time. We recommend stepwise superficial parotidectomy at one or two-week intervals as treatment of bilateral Warthin's tumor.

Irritation fibroma is a reactive hyperplastic lesion caused by chronic stimuli with low intensity in the oral cavity. Irritation fibroma is common in middle-aged females but it may also occur at any age and sex. Clinical characteristics of irritation fibroma are similar to other reactive lesions or benign tumors, therefore, histological examination is essential to make an accurate diagnosis. This case report presents two cases of irritation fibroma occurred on the gingiva in young males. Two male patients in their 20s and 30s of age visited the clinic for the evaluation and treatment of painless gingival overgrowth in the anterior region. Clinically, the lesions were well-defined and firm, with similar color and texture to the adjacent normal gingiva. Excisional biopsy under local anesthesia was conducted with a scalpel, and the lesions were completely removed. Histopathologically, connective tissue consisting of dense collagen bundles, proliferation of fibroblasts and minor infiltrated inflammatory cells were observed. Based on the clinical and histopathological findings, the diagnosis of irritation fibroma was confirmed in both cases.

Traumatic neuromas are rare benign tumors that are common after trauma or surgery and are usually accompanied by obvious symptoms of pain. Most reports show neuromas in the face, neck, and limbs, and the traumatic neuroma of the medial plantar nerve has rarely been reported. We encountered a traumatic neuroma of the medial plantar nerve after a deep laceration mimicking a foreign body granuloma. A small mass lesion was found around plantar aponeurosis with heterogeneous high signal intensity in the T2 fat suppression view and slightly enhanced intensity in the magnetic resonance imaging that suggested a foreign body granuloma. The lesion was diagnosed pathologically as a traumatic neuroma. A satisfactory clinical result was obtained after excision of the traumatic neuroma and burial of the proximal and distal stumps to the adjacent muscle at the secondary operation.

Gastric hemangiomas are rare benign vascular tumors that can cause severe gastrointestinal system bleeding. We presented the case of a neonate with fresh bleeding and melena from the orogastric tube and detected gastric hemangioma in esophagogastroduodenoscopic examination. Propranolol is widely used in treatment of cutaneous hemangiomas and non-gastric gastrointestinal system hemangiomas. However, the surgical approach is preferred for treating gastric hemangiomas, and there are few reports of gastric hemangiomas associated with non-surgical treatment. Gastric hemorrhage decreased with antacid and somatostatin treatment. Propranolol treatment was initiated before the surgery decision. After three weeks of treatment, we observed regression in the hemangioma with endoscopic evaluation. During the course of treatment, the patient's gastrointestinal system bleeding did not recur, and there were no side effects associated with propranolol.

Infantile hepatic hemangioendotheliomas (IHHEs) are benign vascular tumors, but can be associated with the life-threatening complications, such as congestive heart failure, disseminated intravascular coagulation, and massive bleeding. Various therapeutic options have been developed and the treatment response depends on the patient's clinical status and the nature of the lesion. In the case of a symptomatic IHHE, a non-invasive and precise diagnosis should be performed promptly before the therapeutic method is chosen. Additionally, it should be kept in mind that the residual lesions have malignant potential. We report a case of a congenital giant IHHE that was successfully reduced in size by interferon-$\alpha$ and completely removed by surgical tumor resection with a hepatic lobectomy.

Hemangioma is one of the most common congenital tumors in the region of the face and neck. Although histologically benign, these facial masses are clinically malignant for their deforming and inexorable growth, especially in so-called 'cavernous hemangioma'. Carvenous hemangioma is the most common primary tumor occurring in the adult orbit. This tumor has symptoms that characteristically develop over several years with slowly progressive proptosis, eyeball deviation, hyperopia, diplopia and optic nerve compression. Today, hemangiomas are being treated by various methods; steroids, electrocoagulation, injection of sclerosing agent, cryotherapy, radiation therapy, laser therapy, and surgical treatment, etc. In principle, surgical approaches to the orbit must provide maximum safety and optimal visualization. We have experienced a case of large cavernous hemangioma in the orbit inferolaterally. The surgical treatment of tumor was achieved by the bicoronal approach combined with inferomedial and inferolateral orbitotomy. This surgical approach allows better visualization of the tumor and greater protection of essential anatomic structures. We obtained satisfactory results in terms of aesthetic and functional consideration. We present our case with a brief review of the literature related to orbital cavernous hemangioma.
