Abstract
A 11-month-old male intact Shar-Pei (26. 5 kg) was presented for a bilateral sublingual swelling of 4 months duration. The exploration of the oral cavity highlighted the presence of bilateral sublingual swellings, primarily consistent with bilateral ranula. The bilateral disease was treated with two subsequent surgeries 4 weeks apart. During the surgery, after removing an elliptical portion of the mucosa of the sublingual swelling, the presence of gelatinous tissue was visualized, and no saliva was present. The result of histological exam was oral mucinosis. At the subsequent follow-up the dog was in excellent conditions, without any symptoms. 1 month after the last operation, the dog underwent a visit in sedation to better evaluate the oral cavity. Both surgical sites were well-healed and without the presence of relapses. Upon 8 months follow-up the patient remained free of disease. This is the first reported case of oral mucinosis in sublingual mucosa in dogs. In this case the surgical treatment was curative.

Abstract
BACKGROUND Oral focal mucinosis (OFM) is a rare benign condition of unknown etiology, considered the oral counterpart of cutaneous focal mucinosis. We report the clinicopathologic features of 21 cases of OFM in conjunction with a review of the literature. METHODS Clinical data were collected from the records of five oral and maxillofacial pathology services. All cases were evaluated by hematoxylin and eosin staining, histochemistry, and immunohistochemistry (vimentin, S-100, α-SMA, CD34, and mast cell). RESULTS The series comprised 14 females (66.7%) and seven males (33.3%), with a mean age of 48.2 ± 20.7 years (range: 8-77 years) and a 2:1 female-to-male ratio. Most of the lesions affected the gingiva (n = 6, 28.6%) and presented clinically as asymptomatic sessile or pedunculated nodules with fibrous or hyperplasic appearance. All cases were negative for S-100 protein, CD34, and α-SMA and positive for Alcian blue staining. Conservative surgical excision was the treatment in all cases, and there was only one recurrence. CONCLUSION OFM is a rare benign disorder that is often clinically misdiagnosed as reactive lesions or benign proliferative processes. Dermatologists and pathologists should consider OFM in the differential diagnosis of soft tissue lesions in the oral cavity, mainly located in the gingiva.

Abstract
BACKGROUND Oral focal mucinosis, the oral counterpart of cutaneous focal mucinosis, is a rare disease. As it has no characteristic clinical or radiological features, diagnosis is established by histopathological and immunohistological examination. We present three cases of oral focal mucinosis occurring in the retromolar (which is extremely rare) and gingival regions. CASE PRESENTATION Case 1 involved a 26-year-old Japanese man with radiolucency in the right retromolar region on panoramic radiograph and computed tomography; no obvious protrusion was observed in the region. This finding was clinically diagnosed as a tumor of the retromolar region. Case 2 involved a 60-year-old Japanese woman. A tumor-like mass of tissue was identified on the buccal gingiva at the maxillary right canine and first premolar region. The lesion measured 7 × 6 mm and exhibited elastic hardness and healthy-colored mucosa. The lesion was diagnosed as an epulis. Case 3 involved a 47-year-old Japanese woman. A tumor-like mass of tissue was identified on the buccal gingiva at the maxillary right canine and first premolar region. The lesion measured 10 × 10 mm and exhibited elastic hardness and redness of the surface mucosa. This lesion was also diagnosed as an epulis. Resection was performed in all three cases, and the lesions were histopathologically diagnosed as oral focal mucinosis. Postoperative courses were uneventful and, thus far, there have been no recurrences. CONCLUSIONS Although it is difficult to diagnose oral focal mucinosis based on clinical symptoms and imaging findings, the disease should be considered a possibility when diagnosing benign oral tumors. We believe that an emphasis on histopathologic study is essential to confirm the clinical suspicion.

Abstract
Oral focal mucinosis (OFM) is a rare connective tissue disorder characterized by myxoid degeneration of submucosal connective tissue. It usually presents as gingival or mucosal overgrowth. Due to its uncommon occurrence and lack of pathognomonic clinical or radiological features, diagnosis mainly relies on histopathological evaluation. The paper reports a rare case of large OFM in a 58-year-old female patient involving the posterior maxilla and hard palate. Diagnosis of the lesion was established based on histopathological and immunohistochemical analysis. The lesion was excised surgically and showed no recurrence at 1 year follow-up. The cases presented intend to bring OFM to the attention of oral pathologists and clinicians while considering the differential diagnosis of myxoid lesions of oral cavity.

Abstract
Oral focal mucinosis (OFM) is a rare mucosal lesion of unknown etiopathogenesis. It is considered the oral counterpart of cutaneous focal mucinosis. From the anatomo-pathological point of view it is characterised by a focal degeneration of myxoid type of connective tissue. A literature survey revealed 50 reports of OFM cases worldwide. Here, we present an even more rare case with tongue involvement. Particular emphasis is placed on diagnostic-differential aspects of this kind of lesion, both from the clinical and the histopathological point of view, in respect to other manifestations of tongue mucosa.

Abstract
BACKGROUND Oral focal mucinosis (OFM) and cervical external root resorption are both rare lesions with an unknown etiology. In this article we report on a rare occurrence of OFM associated with cervical external root resorption. METHODS A 44-year-old female patient presented with sharp pain while drinking cold beverages and a firm localized gingival overgrowth adjacent to the buccal aspect of tooth #19. An excisional biopsy of the gingival lesion was taken and a deep cavity was found in the buccal aspect of the root. The cavity was restored with an amalgam filling. RESULTS The histological findings were of a well-circumscribed lesion composed of myxomatous connective tissue, which contained numerous stellate-shaped fibroblasts. Based on the findings, a diagnosis of OFM was made. CONCLUSION A rare case of OFM and cervical external root resorption occurring in the same site was described. A possible link between these 2 phenomena was hypothesized.

Abstract
BACKGROUND Peripheral (extraosseous) odontogenic tumors are rare, and reports in the literature have mainly been single case reports or a small series of cases. The aim of this study was to determine the relative frequency of peripheral (extraosseous) odontogenic tumors relative to one another and relative to their central (intraosseous) counterparts in an oral pathology biopsy service and to compare these data with information available in the literature. METHODS The files of the Pacific Oral and Maxillofacial Pathology Laboratory of the University of the Pacific, San Francisco, CA, USA, served as the source of material for this study. Files were systematically searched for all cases of peripheral odontogenic tumors (POTs) during a 20-year-period. RESULTS There were 91,178 cases accessed in which central and POTs were identified in 1,133 (1.24%), central tumors in 1,088 (1.2%), and peripheral tumors in 45 (0.05%). Peripheral tumors accounted for 4% of all 1133 central and POTs. Peripheral odontogenic fibroma (PODF) was the most common of the 45 POTs accounting for 51.1% (23 cases) followed by peripheral ameloblastoma (PA) 28.9% (13 cases) and peripheral calcifying cystic odontogenic tumor (PCCOT) 13.3% (six cases). Peripheral calcifying epithelial odontogenic tumor, peripheral ameloblastic fibroma, and peripheral ameloblastic carcinoma were also identified--each comprised 2.2% (one case each). PODF was more common than its central counterpart by a 1.4:1 ratio. This was the only peripheral tumor that was more common than its central counterpart. PA accounted for 9.3% of all ameloblastomas and PCCOT for 26% of all calcifying cystic odontogenic tumors. CONCLUSION There is only scarce information in the literature on the relative frequency of POTs. Additional studies should be conducted to determine the true relative frequency. To ensure accuracy, pathologists with experience in the field of odontogenic tumors should conduct these studies. Intraosseous tumors that perforate through the bone to the gingival tissue, clinically presenting as 'peripheral tumors' should be excluded.

Abstract
AIMS To describe 15 cases of oral focal mucinosis (OFM) and compare these to previously reported cases. METHODS Cases diagnosed as OFM in the period 1981-2003-were reviewed. Clinical information provided at the time of submission of each specimen was retrieved and supplemented by additional clinical details provided by the respective clinician at the time of compilation of this paper. The literature was reviewed. RESULTS OFM presented as an innocuous soft tissue swelling that may be either pedunculated or sessile. The gingiva was confirmed as the most common site for OFM, with a predominance of females affected. Microscopically, OFM is characterised by an area of myxoid tissue which is usually well-defined. The lesion is periodic acid-Schiff (PAS)-negative and alcian blue-positive, with pre-digestion with hyaluronidase preventing the alcian blue staining. As the differential diagnosis includes myxoid neural lesions, S100 staining is important in establishing the diagnosis, with cases of OFM being negative. CONCLUSIONS The cause of OFM remains unknown. The cases presented in this paper bring OFM to the attention of anatomical pathologists when considering the differential diagnosis of myxoid lesions of the oral cavity.

Abstract
BACKGROUND Oral focal mucinosis is a rare disease of unknown etiology, where the connective tissue undergoes a focal myxoid degeneration. METHODS We describe a 48-year-old patient who was referred for a firm, tender mass located on the gingiva of the left central mandibular incisor. The first clinical impression at examination was that of a periodontal abscess. RESULTS The lesion underwent a biopsy, and the final microscopic diagnosis was oral focal mucinosis. CONCLUSIONS It must be stressed that in most focal gingival lesions, a preoperative diagnosis can be almost impossible.

Abstract
Ectomesenchymal chondromyxoid tumor is a newly described benign neoplasm that presents clinically as a firm, painless, slow-growing mass that typically involves the anterior dorsal tongue. It has been reported to occur over a wide age range (9 to 78 years) and has no apparent sex predilection. Histologically, the tumor is composed of a well-circumscribed, unencapsulated lobular proliferation of fusiform and polygonal cells in a chondromyxoid matrix. Features such as multilobulated nuclei, foci of cellular atypia, and infiltration may be present. Though disturbing, these do not appear to indicate malignant behavior. We report three cases of ectomesenchymal chondromyxoid tumors that confirm the previously described clinical, histologic, and immunohistochemical features. In addition, we describe the ultrastructural features of one of the cases.
