Bilateral parotid swelling in a child--a case report

Numerous causes for bilateral parotid swellings have been identified. It must be assumed that systemic factors play a key role, thereby the attainment of a definitive diagnosis requires a familiarity with full range of possible etiologies for these swellings. Differential diagnostic skills must be implemented to achieve a precise diagnosis. A case of bilateral parotid swelling in a child is presented and differential diagnosis is discussed.     

Bilateral parotid glands aplasia: a case report and literature review

Objectives

Bilateral parotid gland aplasia is a rare congenital anomaly that almost consistently leads to xerostomia and caries. It is often associated with other congenital craniofacial abnormalities. The objective was to describe a case with asymptomatic bilateral parotid gland aplasia and to review previously reported cases.

Methods

Panoramic radiograph, computed tomography and magnetic resonance imaging were obtained and an in-depth assessment of patient’s dental status and sequence analysis of FGF10, FGFR2 and FGFR3 genes were performed. Previous reports of bilateral parotid gland aplasia were assessed.

Results

In a 64-year-old woman with extensive basal cell carcinoma of nasal skin an incidental bilateral parotid gland aplasia was noted during radiotherapy treatment planning. Dental status revealed surprisingly numerous (n?=?15) teeth without active caries lesions. No other craniofacial abnormalities were identified. To rule out most probable syndromes associated with parotid gland aplasia, sequence analysis of FGF10, FGFR2 and FGFR3 genes was performed showing no pathogenic variants. With a literature review, we identified 148 cases of salivary gland aplasia in which median age at diagnosis was 21 years and one third were asymptomatic. In only 10 of these cases, the patients presented with bilateral aplasia of parotid glands without other craniofacial abnormalities.

Conclusions

Absence of salivary glands can have a debilitating effect on oral health and is often accompanied by other craniofacial abnormalities. However, relatively frequent asymptomatic course suggests that this rare malformation is probably underdiagnosed. Therefore, we propose systematic reporting of salivary gland aplasia to assess its true prevalence in general population.

     

Bilateral tonsillolithiasis: a case report

Although tonsilloliths are reported to be fairly common, florid cases casting distinct radiopaque shadows on panoramic radiographs are not often reported. This report illustrates such a case as an incidental finding in an asymptomatic 38-year-old female dental patient. Panoramic radiography revealed distinct radiopaque shadows over the ascending rami of the mandible bilaterally. These radiopacities were localized to the palatine tonsils by computerized tomographic inspection. Tonsillectomy was performed and tonsillolithiasis was confirmed by histopathologic examination.     

Polycystic parotid disease: a case report

A case report of a 14-year-old girl, presumed to have PPD, is presented. Those manifestations of this patient's disease that can be added to the classic picture of PPD include a decreased salivary flow rate and a sialochemistry that reflects a mild chronic parotitis. In addition, cysts and sialoliths were demonstrated grossly rather than microscopically.     

Bilateral cracked teeth: a case report

This report presents a case of undiagnosed, cracked, bilateral, maxillary molars. Both teeth were non-carious and unrestored. Failure to diagnose the initial cracks resulted in further splitting, and finally complete vertical fractures. The problem of diagnosis is highlighted and the treatment of the cracked tooth to prevent its fracture is discussed.     

Bilateral bifid mandibular condyle: a case report

Bilateral bifid mandibular condyle is a rarely seen malformation. The aetiology of bifid condyle is not completely understood, although developmental anomaly, traumas, condylar fracture, teratogenic embryopathy and surgical condylectomy may all be causative factors. Although a few studies on human dried skulls tried to shed light on this entity it remains obscure. As most bifid condyle subjects have no complaint related to temporamandibular joint(TMJ), the cases are generally diagnosed through incidental radiographic findings. The case of a 54-year-old female is presented. In a panoramic radiograph obtained after a clinical examination, bilateral bifid mandibular condyle was observed. The open-closed lateral radiograph of the TMJ (obtained using the TMJ-specific program of the panoramic device) demonstrated duplication of the right and left condyles. In order to better evaluate the TMJ morphology and to eliminate pathologies such as fractures that might be missed with conventional radiographs, a computed tomography scan was also obtained. The joint head orientation was observed in the mediolateral direction. The case is discussed in the context of the relevant literature. Until large population-based studies are undertaken and further experimental studies are performed, bifid condyle will remain an incidental finding of anatomic variation rather than a clinically informative observation.

Bilateral temporalis muscle hypertrophy: a case report

Although masseteric hypertrophy is common and can be accompanied by temporalis hypertrophy, temporalis hypertrophy by itself is an exceptional finding. A patient, a chronic bruxer who was receiving psychiatric care and psychotherapeutic medications, complained of moderate discomfort and swelling in both temporal areas. It is believed that the patient's long-term stress-related sleeping problem was causing her bruxism. Of great interest was the fact that chronic bruxing had resulted in the rare occurrence of temporalis muscle hypertrophy without a coexisting masseteric hypertrophy.     

Bilateral maxillary dentigerous cysts: a case report

Dentigerous cysts are benign odontogenic cysts that are associated with the crowns of permanent teeth. They are usually single in occurrence and located in the mandible. Multiple cysts are reported in patients with conditions such as mucopolysaccharidosis and basal cell nevus syndrome. We present the radiologic findings of bilateral impacted maxillary cuspids with dentigerous cysts displacing the maxillary sinuses in a nonsyndromic patient, a condition that, to our knowledge, has not been previously reported.

腮腺肿瘤常常表现为单发,多发性的腮腺肿瘤发生概率极低.本文报道1例罕见的双侧腮腺肿瘤病例,且病理性质不同,一侧为多形性腺瘤,一侧为基底细胞腺瘤,并结合文献讨论这2种病理类型的腮腺肿瘤的临床表现、诊断及治疗.     

Congenital imperforate parotid duct openings: a case report

The apparent distress of a 3-month-old baby whilst feeding was investigated by his general medical practitioner. Swellings were noted in the parotid duct regions of the vestibule which enlarged and almost met in the midline when the baby cried. Incision of the swellings relieved the feeding difficulties.     

Bilateral supplemental maxillary central incisors: a case report

Hyperdontia is a developmental anomaly that is hypothesized to arise from multiple causes. Supernumerary teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. When such teeth remain embedded, they may cause disturbances to developing teeth. Erupted supernumerary teeth can cause aesthetic or functional problems, especially when situated in the maxillary anterior region. Before a definitive diagnosis and treatment plan can be developed, it is essential to clinically and radiographically enumerate and identify supernumerary teeth. Supplemental central incisors are rare and bilateral cases are even rarer: only five cases have been reported in the literature to date. We describe a case of bilateral supplemental maxillary central incisors and discuss the management of supernumerary teeth.     

Bilateral condylar resorption in dermatomyositis: a case report

Polymyositis is an inflammatory disease commonly affecting the striated muscle. When it is accompanied by characteristic skin lesions, the condition is called dermatomyositis. Bilateral condylar resorption has been reported with autoimmune conditions and chronic systemic steroids. We report the first documented case of bilateral condylar resorption in a patient with dermatomyositis. Possible etiologic factors and treatment outcomes are discussed.     

Unilateral agenesis of the parotid gland: a case report

Agenesis of the parotid gland is an extremely rare condition and may be partial or total, unilateral or bilateral, and may occur on its own or associated with other developmental abnormalities. We report a case of unilateral agenesis of the parotid gland without involvement of other major salivary glands together with a compensatory hypertrophy of the contralateral parotid gland.     

Bilateral femoral dysgenesis syndrome: a case report.

This paper reports a child with the Bilateral femoral dysgenesis--unusual facies syndrome (BFD-UF). The child has, in addition to previously reported findings, a ventricular septal defect with valvar and infundibular pulmonic stenosis, absence of the labia majora, bilateral syndactyly of the second and third toes, bifid great right toe and a pilonidal sinus. The similarity to cases of Caudal Regression Syndrome (phocomelic diabetic embryopathy) is noted.
