15例下颌下腺复发性多形性腺瘤临床病理分析

目的：观察下颌下腺复发性多形性腺瘤的临床和组织病理学特征,探讨其病因与治疗。方法：回顾分析2005 年6 月—2017 年6月我院诊治的15 例下颌下腺复发性多形性腺瘤患者的临床和病理资料。结果：15例患者中,男4例（26.67%）,女11例（73.33%）;年龄25~73岁,平均年龄39.33岁;3例（20%）复发2次,其余12例（80%）复发1次,平均复发间期是16.3 a。所有患者均采用肿物及下颌下腺切除术（除2例前次手术已切除下颌下腺者外）,术后病理均证实为复发性多形性腺瘤,多结节生长且大多包膜不完整。随访1~13 a,中位随访时间6 a,仅1例（6.67%）患者可疑复发,因其年龄较大,无手术意愿而未行再次手术治疗。结论：下颌下腺复发性多形性腺瘤尚不多见,其临床病理特征与原发性多形性腺瘤类似,手术是有效的治疗方式。

Giant pleomorphic adenoma of the submandibular gland. Case report

Salivary glands are sites for a great variety of tumors. The parotid gland is the most common site followed by the submandibular gland. The pleomorphic adenoma represents the 60-70% of all tumors involving the major salivary glands, while the submandibular gland is involved in 8% of cases. The pleomorphic adenoma of the submandibular gland is rare and can present difficulty in diagnosis. The heterogeneous histology, a possible malignant transformation, an incomplete capsule that can determine a recurrence, are the most important characteristics of pleomorphic adenoma. A complete surgical removal of the tumor is the treatment of choice. In the case presented, the mass showed an unusual vascularization and remarkable dimensions.     

Synchronous mucoepidermoid carcinoma of tongue and pleomorphic adenoma of submandibular gland

Presentation with synchronous salivary gland tumors is rare, with the most typical combination being Warthin's tumor and pleomorphic adenoma of the parotid gland. Involvement of minor salivary glands in such occurrences is extremely uncommon. We report a case of simultaneous mucoepidermoid carcinoma of the tongue and pleomorphic adenoma of the submandibular gland in a 40-year-old woman. The submandibular mass was initially considered to represent regional lymph node tumor metastasis but later was shown to be an intraglandular primary neoplasm.     

Maxillofacial diagnostic features of the enigmatic metastasizing pleomorphic adenoma

Considering the confusion in the literature regarding local recurrence, spread, or metastases of pleomorphic adenoma (PA) in the head and neck region, the aim of this study was to enhance understanding of the characteristics of metastasizing pleomorphic adenoma (MPA) by reviewing the literature and presenting a case. English language articles with proof of metastases were included in the literature review. Of the 80 cases in the literature with MPA, 46 were female and 33 were male (sex missing for one case). Thirty-five percent of the neoplasms affected the bones; the maxilla was affected in five cases and the mandible in three. The parotid was the primary site in 72.5% of cases and the submandibular gland in 16.2% of cases. The local recurrence rate was 70%. The mean interval between primary PA and MPA was 15.52 years. The total mortality rate was 8.7%. A case of PA of the submandibular gland that recurred after surgical excision and metastasized (confirmed by the presence of intact cortical borders) to the ipsilateral mandibular body, upper lip, and neck is described. The high mortality rate in a histologically defined benign disease that metastasizes demands that management include careful primary excision and long-term clinical follow-up.     

MR imaging of tumor-like swelling in the submandibular region

Tumor-like swellings in the submandibular region were evaluated in seven patients with MR imaging. Two cases of pleomorphic adenoma and two of sialoadenitis were selected as examples of submandibular gland lesions, while a plunging ranula, dermoid cyst and lymphadenitis were selected as examples of extraglandular lesions. The pleomorphic adenoma was connected with the remaining gland on T1-weighted images. The sialoadenitis showed changes in the size, signal intensity and homogeneity of the submandibular gland itself. On the other hand, extragland lesions showed zonal interpositions between the lesion and the submandibular gland, which showed either low or high signal intensity on T1-weighted images. On T1-weighted images, the intensity of all of the lesions was either lower than or the same as the normal submandibular gland. On the other hand, all lesions showed higher signal intensity, ranging from slight to very high on T2-weighted images. Sharp margins were seen in all lesions except one sialoadenitis. The sialoadenitis showed inflammatory infiltration into the surrounding tissue. A homogeneous internal pattern was observed in the case of cystic lesions, while an inhomogeneous internal pattern was noted in the pleomorphic adenoma and in the inflammatory lesions. Gd-DTPA enhanced the T1-weighted images in three cases. Pleomorphic adenoma and lymphadenitis were enhanced inhomogeneously, whereas the ranula was not enhanced.     

A case of carcinosarcoma arising in the submandibular gland

A 54-year-old man presented with an 8-year history of a hard asymptomatic mass of the left submandibular area. Total excision of the left submandibular gland with radical neck dissection was performed under a diagnosis of a submandibular tumor, probably a malignant mixed tumor. The pathologic diagnosis was carcinosarcoma consisting of carcinomatous and sarcomatous elements. The epithelial component was composed of squamous cell carcinoma, undifferentiated carcinoma, and adenocarcinoma. The nonepithelial component was composed of chondrosarcoma, osteosarcoma, spindle cell sarcoma, rhabdomyosarcoma, and liposarcoma. In the central area of the tumor, a few remnants of benign pleomorphic adenoma were identifiable. The finding suggested that in our patient, the carcinosarcoma arose from a preexisting pleomorphic adenoma. In view of the expected aggressive nature of the tumor, the patient was treated with postoperative radiotherapy of 60 Gy total, in 30 daily fractions of 2 Gy, and chemotherapy. He currently remains well and free of disease 24 months after treatment.
