Mammary analogue secretory carcinoma in minor salivary gland

ABSTRACT Mammary analogue secretory carcinoma is a rare neoplasm usually confused with other neoplasms in the salivary glands region. It has great similarity with the breast carcinoma. We report a case of a patient who presented with gingival submucosal bleeding and lesion, with the initial histopathological examination revealing salivary gland neoplasm of low crane. Computed tomography revealed the lesion near the tooth 27, with extension to the floor of the left maxillary sinus and to the palate mucosa. Resection of the infra-structure was performed, with a diagnosis of breast cancer secretory carcinoma in the minor salivary gland.

Suppurative minor salivary gland sialolithiasis

ABSTRACT Sialolithiasis is a common nonneoplastic disease of the major salivary glands that often affects the submandibular glands. Minor salivary gland involvement by sialolithiasis is uncommon, with only 273 cases reported. A long clinical history, acute symptoms, and mucopurulent discharge are unusual features of these cases. Herein, we report the case of a 63-year-old woman who complained of symptomatic nodular swelling of the buccal mucosa associated with purulent discharge for several days. The clinical history lasted 15 years, with episodes of asymptomatic non-suppurative swelling in the same area. The patient underwent surgical excision. The microscopic examination revealed chronic nonspecific sialadenitis associated with psammomatous calcifications, confirming minor salivary gland sialolithiasis. After 3 years of follow-up, the patient was free of symptoms. Patients with sialolithiasis are usually asymptomatic; however, swelling, pain, and fistula may be present in rare cases. The presence of purulent exudate should lead to the differential diagnosis of stomatitis glandularis, a rare inflammatory condition affecting the minor salivary glands. Sialolithiasis and stomatitis glandularis should be considered in the clinical differential diagnosis of symptomatic suppurative nodular swelling affecting the oral mucosa, and histopathological analysis is necessary for the diagnosis.

Pleomorphic adenoma of the hard palate with calcifications: an unusual presentation / Adenoma pleomórfico del paladar duro con calcificaciones: una presentación inusual

Pleomorphic Adenoma (PA) is the most common benign salivary gland tumor. The most common sites for minor salivary gland from which PA arises are the palate followed by the lips and buccal mucosa. Calcifications are a common finding in major salivary glands with chronic inflammatory disorders. Major salivary gland tumors rarely show calcifications and it is less common to find them in minor salivary gland tumors. We report a case of pleomorphic adenoma of the hard palate in a 67-year-old female patient with intra-tumoral, irregular and scattered calcifications visible on computed tomography (CT). The treatment was complete surgical excision of the lesion. The diagnosis was confirmed with the histopathological study.

El adenoma pleomórfico (AP) es el tumor benigno de las glándulas salivales más común. Los sitios de mayor frecuencia donde surge el AP en glándulas salivales menores es el paladar seguido de los labios y la mucosa bucal. Las calcificaciones son un hallazgo común en las glándulas salivales mayores con trastornos inflamatorios crónicos, pero en el caso de tumores rara vez muestran calcificaciones y es menos común encontrarlos en tumores de las glándulas salivales menores. Presentamos un caso de adenoma pleomórfico del paladar duro en una paciente de 67 años con calcificaciones intratumorales, irregulares y dispersas visibles en la tomografía computarizada. El tratamiento fue la extirpación quirúrgica completa de la lesión. El diagnóstico se confirmó con el estudio histopatológico

Adenoma canalicular multifocal del labio superior: reporte de un caso y revisión de la literatura / Multifocal canalicular adenoma of the upper lip: a case report and literature review / Adenoma canalicular multifocal do lábio superior: reporte de um caso e revisão da literatura

RESUMEN El adenoma canalicular (AC) es una neoplasia epitelial benigna infrecuente de las glándulas salivales menores localizada principalmente en el labio superior. Se manifiesta como un nódulo menor de 3 centímetros, indoloro, no ulcerado y de crecimiento lento. El diagnóstico diferencial se debe hacer con otros tumores de las glándulas salivales como adenoma de células basales, adenoma pleomórfico y carcinoma adenoide quístico. Se presenta el caso de una paciente con antecedente de adenoma canalicular en el labio superior extirpado 13 años antes, que consultó en junio de 2015 por una lesión de 8 mm de diámetro en la misma localización. En septiembre del mismo año se resecó la lesión, incluyendo la glándula salival accesoria adyacente. El estudio histopatológico confirmó nuevamente el diagnóstico de AC y mostró multifocalidad del tumor en la glándula salival accesoria.

SUMMARY Canalicular adenoma is an unusual benign epithelial neoplasm of the minor salivary glands located primarily on the upper lip. It appears as a slowgrowing node, less than 3 cm in diameter, painless, and non-ulcerated. Differential diagnosis should be made with other tumors of the salivary glands such as basal cell adenoma, pleomorphic adenoma and adenoid cystic carcinoma. We report the case of a female with a history of canalicular adenoma (CA) on the upper lip, removed 13 years before, who consulted on June 2015 because of a mass, 8 mm in diameter with the same location as the previous lesion. On September 2015, the lesion and the accessory salivary gland were removed. Histopathological study found the same diagnosis as before (CA), and revealed multifocality of the neoplasm in the accessory salivary gland.

Minor intraoral salivary gland tumors: a clinical-pathological study / Neoplasias intraorais de glândula salivar menor: estudo clínico-patológico

ABSTRACT Objective To evaluate the clinical-pathological profile of patients with minor salivary gland neoplasms. Methods A retrospective study of specific cases diagnosed as benign and malignant tumors of the minor salivary glands was performed. The data were collected from medical records of patients seen at a hospital over a period of 15 years. The sample was made up of 37 cases. For the pathological study, slides containing 5μm thick sections stained with hematoxylin and eosin were used. The data were tabulated using descriptive statistics. Results Malignant neoplasms represented 70.3% of cases. The mucoepidermoid carcinoma was the most common neoplasm (45.9%), followed by pleomorphic adenoma (24.4%). Most patients were female (70.3%), aged between 71 and 80 years. The palate (67.6%) and the retromolar region (10.8%) were the most affected sites. Conclusion Mucoepidermoid carcinoma was the most common tumor in minor salivary glands. These tumors are more common in females aged over 40 years. The palate was the most common affected site.

Abnormal expression of T regulatory cells in primary Sj(o)gren's syndrome / 中华风湿病学杂志

Objective This study was designed to investigate the expression of T regulatory cells (Treg) in the peripheral blood and salivary gland of patients with primary Sj(o)gren's syndrome (pSS).Methods The expression of Treg was measured by flow-cytometry analysis in 23 pSS patients and 15 healthy controls.CD4 positive cells were sorted by immunomagnetic beads,Forkhead box protein P3 (Foxp3) mRNA was extracted,real time polymerase chain reaction (RT-PCR) was used to measure Foxp3 mRNA.For the study of salivary gland,five primary billary cirrhosis (PBC) patients without pSS were selected as the control group,the expression of CD4+T cells and Foxp3+ T cells in salivary gland was examined by immunohistochemistry.The result was analyzed by t test.Results The expression of Treg in the peripheral blood of pSS patients [(5±6)％] was lower than healthy controls [(10±5)％] (t=2.190,P=0.036).There was no significant difference in Foxp3-mRNA expression between pSS patients (0.08±0.05) and controls(0.09±0.03 ) (t=0.695,P＞0.05 ).The expression of CD4+ T cells [ ( 30± 10 )％ ] and Foxp3+ T cells [ ( 10.7±5.8 ) ％ ] in the salivary gland of pSS patients increased significantly when compared with PBC control group [CD4+T (11±6)％ and Foxp3+T(3.2+1.1)％ ] (t=4.072,2.840; P＜0.05).Conclusion For pSS patients,the expression of Treg decreases in the peripheral blood,but Treg increases in the salivary gland.The results of this study suggest that Foxp3plays an important role in the pathogenesis of pSS.

Necrotizing sialometaplasia of palate: a case report

Necrotizing sialometaplasia (NS) which mimics malignancy both clinically and histopathologically is an uncommon benign, self-limiting inflammatory disease of the mucus-secreting minor salivary glands. The lesion is believed to be the result of vascular ischemia that may be initiated by trauma. Till date, the diagnosis of NS remains a challenge. This report demonstrates a case of NS in a 73-year-old male patient who presented with an ulcerative lesion in his palate. He had a history of local trauma and was long-term user of salbutamol inhaler. An incisional biopsy was carried out and the diagnosis was established through history, clinical examination, histopathology using Hematoxylin and Eosin stain. The patient was given symptomatic treatment and the lesion healed in about 7 weeks.

Acinic Cell Carcinoma of the Palatine Tonsil: A Brief Case Report

Acinic cell carcinoma (ACC) is a rare, low-grade malignancy of the salivary glands. Most cases occur in the major salivary glands, especially the parotid gland, with only a few cases involving the minor salivary gland previously described. A 67-year-old male patient was admitted complaining of an obstructive feeling in the throat. On examination, a lobulated mass in the tonsillar surface was noticed. Tonsillectomy was performed under general anesthesia. Histopathological examination of the mass revealed sheets of large, polygonal acinar cells with granular, slightly basophilic cytoplasm, which led to the diagnosis of ACC. Here, we present a case of low-grade ACC of the palatine tonsil, which we believe to be the first reported case of ACC in this location.

Imaging analysis of pleomorphic adenomas of the minor salivary glands of the palate / 中华放射学杂志

Objective To study the imaging features of the pleomorphic adenomas of the minor salivary glands in the palate and to improve its diagnostic validity. Methods CT and MRI manifestations of 6 patients with palatal pleomorphic adenomas confirmed pathologically were analyzed retrospectively. There were 2 males and 4 females, and their age ranged from 19 to 54 years, with the mean age of 36.3 years. Results Among 6 cases, 5 tumors located in hard palate, and 1 in soft palate. 4 lesions were round like, and 2 were lobulated. Most tumors showed soft tissue density on CT, slightly long T 1 and slightly long T 2 signal intensity on MRI. Cystic degeneration could occur in the central part in some lesions, which appeared as much lower density or obviously long T 1 and long T 2 signal intensity. On post contrast MR scans, the lesions usually showed slightly homogeneous enhancement. Conclusions Pleomorphic adenomas of the minor salivary glands were the most common benign tumors in the palate. Combined with the clinical history, typical CT and MRI appearances, a definitive diagnosis can be made.
