Angiolipoma of the hard palate: a case report and review of the literature.

A case of a large angiolipoma of the hard palate is presented. This constitutes a new site for this type of tumour.     

Angioleiomyoma of the tongue: a case report and review of the literature

Angioleiomyoma (AL) is a benign tumor derived from smooth muscle. The overwhelming majority of ALs occur in the uterus, gastrointestinal tract, or skin; AL of the oral cavity is infrequent, and AL of the tongue is particularly rare. The present report describes a case of AL of the tongue that resulted in a good outcome. We also review the literature with a special emphasis on the etiology of ALs. It is generally agreed that minor trauma, venous stasis, and hormonal changes are etiological factors for AL. The roles of estrogen and progesterone have been particularly emphasized, and the expression of progesterone receptors (PRs) and estrogen receptors (ERs) has been recently evaluated in some cases of AL. To our knowledge, the presence of PRs and ERs has only been evaluated in seven cases of AL arising in different regions of the body including the oral cavity. This is the first report to demonstrate negative expression of both receptors in an AL of the oral cavity. Further study and additional cases are needed to elucidate the influence of PRs and ERs in AL of the oral cavity.     

Glomus tumour of the hard palate: case report and review

Glomus tumours are usually small benign neoplasms that occur in the dermis or subcutaneous tissues of the extremities. They are rare in the oral cavity, only 18 cases having been reported in the medical journals to our knowledge. They arise from the epithelioid glomus cells that normally reside in the stratum retinaculare corii of the skin and are concerned with temperature regulation. We report the clinical, morphological and immunohistochemical features of a case of glomus tumour of the hard palate.     

Osteolipoma: a review of the literature and a rare case report

Objectives

Lipomas are the most common benign mesenchymal tumors of soft tissue. According to previous studies, 1–4% of the cases has been observed in the oral cavity. A histological variant of lipoma featuring bone formation is called osteolipoma and has been very rarely observed (less than 1% of the total). In order to make a meaningful addition to this rare knowledge base, our study aims to provide a literature review and to report an additional case of osteolipoma.

Methods

An electronic search in the PubMed database with the keyword “osteolipoma” was conducted. Among 69 search results, only the cases of osteolipoma located in the “oral cavity” were included in this study. The findings of the previously reported 20 cases (in English) of osteolipoma of the oral cavity were organized in a table along with a new case of osteolipoma located in the mandibular buccal vestibule with radiological and histopathological findings provided by the authors.

Results

Osteolipoma affects both sexes and usually emerges in middle-aged or elderly patients with a long history of slow progression. Different imaging techniques may be utilized in the radiographic evaluation.

Conclusion

Differential diagnosis includes a wide range of lesions; therefore, the clinical and radiographic evaluation should be confirmed by histopathological examination. The suggested treatment is complete surgical excision and follow-up, and the prognosis is generally good.

     

Leiomyoma of the hard palate: a case report

Leiomyoma is a benign smooth muscle tumor that is very rarely located in the oral cavity. It is accepted that the smooth muscle giving rise to this tumor corresponds to the tunica media of the arteries. The tumor can develop at any age, with no clear gender predilection, and typically manifests as a slow-growing, asymptomatic lesion. The diagnosis is based on the histopathological study, with the use of specific staining techniques, including immunohistochemical markers. Treatment consists of complete resection of the lesion, with due safety margins. We present the case of a 57-year-old male with a tumor located for the previous four months in the region of the hard palate, adjacent to the left upper premolars. After surgical resection with safety margins, hematoxylin-eosin staining and immunohistochemical study confirmed the diagnosis of leiomyoma.     

Intranodal hemangioma of the oral soft tissues: a case report of a rare entity with review of the literature

The presentation of a primary vascular tumor in a lymph node is a rare occurrence. Only 16 documented cases have been reported to date, with none described in the oral soft tissues. This case report presents the first occurrence of an intra-nodal hemangioma of the oral soft tissue in an 11-year-old girl. A review of the literature is also presented.     

Canalicular adenoma of the palate: case report and literature review

Canalicular adenoma is a rare benign salivary gland tumor of the oral cavity, typically located in the upper lip and buccal mucosa and infrequently found on the palate. The tumor is usually confined to soft tissue and rarely presents with bone erosion. A case of a large and locally-aggressive palatal canalicular adenoma is presented. The lesion presented herein was an asymptomatic ulcerated mass with significant bone erosion. The tumor was managed surgically with excision and reconstruction of the resulting palatal defect with a full temporalis muscle flap.     

Jacob's disease: report of a rare case and literature review

Jacob's disease is a rare condition consisting of pseudojoint formation between enlarged coronoid process and the inner surface of the zygoma. The authors report a 45-year-old female patient who presented with limited mouth opening (5 mm) and swelling of the left zygoma. No temporomandibular joint disease was diagnosed. 3D computed tomography images showed a mushroom-shaped coronoid growth with pseudojoint formation medial and superior to the zygomatic arch. Under general anaesthesia, coronoidectomy was carried out through a combined extraoral and intraoral approach. Histopathological examination revealed normal trabecular bone covered with hyaline cartilage. To the best of the authors’ knowledge this case is the fifth typical mushroom-shaped Jacob's disease; only four similar cases have been reported. A review of the literature revealed only 39 histologically proved cases of Jacob's disease cases up to 2010. Aggressive physical treatment was given to improve function and maximum mouth opening, which had increased to 40 mm at 3 months follow-up. The literature concerning this condition's aetiology, pathogenesis, clinical characteristics, diagnosis, and treatment is reviewed.     

Fibrous dysplasia of the maxilla: a case report together with its conventional imaging and dynamic magnetic resonance imaging findings

We previously reported that dynamic contrast-enhanced MRI parameters and time–signal intensity curves (TICs; also known as contrast index curves) are useful for the differential diagnosis of jawbone lesions. In particular, odontogenic fibroma and ossifying fibroma, which possess similar histopathological features (i.e., a mixture of hard and soft tissue components), display unique TIC patterns, and we consider that the TIC patterns of these lesions reflect their hard and soft tissue components. Therefore, fibrous dysplasia, which contains fibrous tissue and immature isolated trabeculae composed of woven bone, is expected to display an interesting TIC. The purpose of this study was to assess the utility of TICs for differentiating between the abovementioned lesions, which have similar histopathological components.     

Carcinoma ex pleomorphic adenoma of the infratemporal fossa: a case report with magnetic resonance imaging findings

The infratemporal fossa is the deep retromaxillary space that corresponds to the inferior aspect of the middle cranial fossa. Although tumors of the infratemporal fossa are uncommon, a variety of neoplasms have been reported to involve this area. They include nasopharyngeal carcinomas, juvenile angiofibromas, and adenoid cystic carcinomas. Rarely, a pleomorphic adenoma (PA) is seen, although carcinoma ex PA, a malignant tumor of the salivary glands arising in a preexisting PA, has not been reported in the literature. Factors affecting the malignant transformation of a PA include tumor recurrence, the age of the preexisting tumor, radiation therapy, advanced age of the patient, and tumor size. Here, we present the case of a 40-year-old woman with carcinoma ex PA of the infratemporal fossa with its associated computed tomography and magnetic resonance imaging findings.     

Local amyloidosis in the hard palate: a case report

Amyloidosis is a rare disease of multifactorial pathogenesis. Localized amyloidosis of the palate is extremely rare and only four cases have been reported. We present the fifth case in which amyloidosis occurred as a nodule in the hard palate of a 74-year-old woman. The nodule was diagnosed as amyloid light-chain amyloidosis. Further investigations did not show systemic involvement. The patient was kept under observation and during 17 months of follow-up had no progression of the lesion and systemic amyloidosis did not develop.     

Glomus tumour of the palate: case report and review of the literature

Glomus tumours are benign vascular tumours, usually located in the skin. Intra-oral glomus tumours are rare. A glomus tumour of the palate is reported, only the fifth such case out of a total of 14 intra-oral glomus tumours in the world medical literature.

A large teratoma of the hard palate: a case report

Congenital teratoma is a rare malformation, and few papers have been published about it. We present a large teratoma that arose from the hard palate in a neonate. The obstructive mass caused maternal polyhydramnios and was identified prenatally by ultrasonography. The mother went into labour at 35 week's gestation at home. The child was in respiratory distress as a result of airway obstruction, and a tracheostomy was done when she was 4hours old. She also had major cardiac abnormalities. The palatal mass was removed successfully at 4 weeks of age. The typical components of a teratoma were identified including immature neural glial tissue.     

Solitary mucosal neuroma of the hard palate: a case report

Mucosal neuroma is rare neurogenic tumour that arises in the oral cavity as a component of multiple endocrine neoplasia type 2b (MEN 2b). We present the case of a histologically confirmed solitary mucosal neuroma of the hard palate in a 49-year-old woman with no other components of MEN 2b.
