Papillary cystadenoma is a rare, benign salivary gland neoplasm containing cystic cavities with intraluminal papillary projections. In the head and neck area, it occurs mainly in major and intraoral minor salivary glands, but rarely in the larynx. We report a case of a 67-year-old female with a chief complaint of hoarse voice diagnosed as laryngeal papillary cystadenoma. This paper emphasizes the need to consider papillary cystadenoma as one of differential diagnosis when benign looking lesions are observed in the larynx, where it uncommonly occurs.

Routine panoramic radiographs often reveal hidden lesions other than those related to the patient's chief complaint [1]. The study aims to determine the prevalence of incidental radiopacities in panoramic views. There are several conditions where calcifications can occur in soft tissue, including major and minor salivary glands, lymph nodes, and blood vessels, such as sialolith, phlebolith, exostosis, dystrophic calcifications, etc. [2]. Interpretation of panoramic radiograph should consider the possibilities of soft tissue calcification super-imposed in bone. Three hundred and sixty (360) panoramic radiographs are included in the study. The prevalence and distribution of radiopacities were documented along with the probable diagnosis. In addition, statistical analysis was done by SPSS software to evaluate the age and gender-related distribution of radiopacities in panoramic radiographs.

Primary Sjögren’s syndrome (pSS) is an autoimmune exocrinopathy of mainly the salivary and lacrimal glands associated with high prevalence of lymphoma. Akt is a phosphoinositide-dependent serine/threonine kinase, controlling numerous pathological processes, including oncogenesis and autoimmunity. Herein, we sought to examine its implication in pSS pathogenesis and related lymphomagenesis. The expression of the entire and activated forms of Akt (partially and fully activated: phosphorylated at threonine-308 (T308) and serine-473 (S473), respectively), and two of its substrates, the proline-rich Akt-substrate of 40 kDa (PRAS40) and FoxO1 transcription factor has been immunohistochemically examined in minor salivary glands (MSG) of pSS patients (n = 29; including 9 with pSS-associated lymphoma) and sicca-complaining controls (sicca-controls; n = 10). The entire and phosphorylated Akt, PRAS40, and FoxO1 molecules were strongly, uniformly expressed in the MSG epithelia and infiltrating mononuclear cells of pSS patients, but not sicca-controls. Morphometric analysis revealed that the staining intensity of the fully activated phospho-Akt-S473 in pSS patients (with or without lymphoma) was significantly higher than sicca-controls. Akt pathway activation was independent from the extent or proximity of infiltrates, as well as other disease features, including lymphoma. Our findings support that the Akt pathway is specifically activated in MSGs of pSS patients, revealing novel therapeutic targets.

Abstract Background: This study evaluated the clinical outcomes of the patients with adenoid cystic carcinoma (ACC) of the minor salivary glands of the palate. Methods: Forty-four patients with stage I–II disease and 14 patients with stage III–IV disease underwent radical excision and reconstruction with a facial-submental artery island flap (FSAIF) and titanium mesh plus a free anterolateral thigh flap (ALTF) and radiotherapy respectively. Patients with stage III–IV disease subsequently received cobalt Co 60 adjuvant radiotherapy. Ki-67 expression was determined semiquantitatively in 52 patients with ACC by based on the cytoplasm staining intensity and percentage of positively stained tumor cells.Results: The median (range) follow-up was 32.9 (14–58) months. Forty-one (71.7%) patients survived without disease recurrence. Nine patients (15.5%) survived with recurrent tumors (four with local recurrence, three with regional recurrence requiring salvage surgery, and two with distant metastasis); among these patients, five had overlapping recurrence. Eight patients (13.8%) died of regional, distant, or multiorgan metastasis (range: 22–42 months). The overall median (95% CI) survival time was 32.5 (25.0–39.5) months, and the median (95% CI) progression-free survival time was 32.9 (28.5–36.9) months. Rates of survival and recurrence differed significantly between patients with low- and high-grade tumors, patients with clinical stage I–II disease and those with stage III–IV disease, patients with and without lymph node metastasis, patients who underwent radical excision with versus without radiotherapy, and patients with low and high Ki-67 expression. Conclusion: Radical resection and reconstruction with FSAIF is the most suitable treatment for stage I–II ACC of the minor salivary glands of the palate. Stage III–IV tumors require radical resection, reconstruction with titanium mesh and free ALTF, and radiotherapy.

Epithelial-myoepithelial carcinoma (EMC) is a rare salivary gland tumor that is histologically characterized by biphasic tubular structures composed of inner ductal and outer clear myoepithelial cells, which is especially uncommon in the minor salivary glands (MSG). Because of its histologic variety, complexity, and heterogeneity, it is sometimes challenging to make the accurate diagnosis. Here, we report a literature review of EMC of the MSGs with our experience of two cases. Incisional biopsy was suggestive of pleomorphic adenoma in Case 1 and pleomorphic adenoma or a low-grade salivary gland carcinoma in Case 2. Both cases were performed intraoral tumor resection, and they have good postoperative courses and are alive with no evidence of local recurrence or metastasis at 31 and 16 months, respectively. Considering that the anatomy, structure, and size of salivary glands are quite different from MSGs, it might be difficult to predict EMCs of the MSG similarly to EMCs of the major salivary glands. This comprehensive review also reports the features of EMC of the MSG cases and the trends of diagnosis and discusses treatment strategy.

Lip lesions are the most common oral mucosal lesions. Mucocele is the second most common benign soft tissue masses of the lips only next to infectious etiology. Tumors of the minor salivary glands of the lip were a rare diagnosis made clinically. Excision and histopathological examination must be done for all the lip lumps as this remains the gold standard for the diagnosis. In this article, we discuss three lip lumps which were clinically suspected as mucocoele turned out to be an unexpected diagnosis which only became clear following excision and histological examination.

Objectives: Adenoid cystic carcinoma (ACC) is a commonly encountered salivary gland malignancy. However, it rarely occurs in the gingiva, an area generally thought to be devoid of minor salivary glands. We present a case occurring in this unusual site and review other reported cases. Methods: A 56 year-old male presented with a right-sided mandibular toothache for 1 year and underwent dental extraction. Due to persistent pain, follow up examination revealed a large gingival lesion. A biopsy was positive for adenoid cystic carcinoma. Results: The patient underwent a complete right segmental mandibulectomy and was reconstructed with a fibular osteocutaneous free flap. Three months postoperatively, during the planning for adjuvant radiation therapy, the patient developed pain in the left mandible. Imaging revealed extensive involvement of the left native mandible. Deep bone biopsies in several areas of the left mandible revealed ACC. He then underwent a complete left hemi-mandibulectomy and reconstruction with a fibular osteocutaneous free flap. Tensor fascia lata suspension slings were placed due to concern for an open mouth deformity attributable to disruption of bilateral masticator slings. He will undergo adjuvant radiation therapy. Our review of the literature revealed 50 cases of gingival ACC published since 1972. Disease recurrence and distant metastases were noted in several patients, occurring at the latest after 30 years follow-up. Conclusions: Given its indolent behavior, high proclivity for late recurrence and metastasis, and overall infrequency, ACC represents a pathology that requires early diagnosis and comprehensive long-term surveillance. While ACC is well described in oral cavity sites with high densities of minor salivary glands, it is not commonly seen in the gingiva. As such, gingival ACC may display a unique biological and/or clinical character. We offer the first literature review of this rare entity.
