RESUMO
PURPOSE: This case describes the successful visual restoration of a patient with end-stage Stevens-Johnson syndrome (SJS) with a severely keratinized ocular surface. METHODS: This study is a case report. RESULTS: A 67-year-old man with SJS secondary to allopurinol sought visual rehabilitation options. His ocular surface was severely compromised from sequelae of chronic SJS, leaving him with light perception vision bilaterally. The left eye was completely keratinized with severe ankyloblepharon. The right eye had failed penetrating keratoplasty, limbal stem cell deficiency, and a keratinized ocular surface. The patient declined both a Boston type 2 keratoprosthesis and a modified osteo-odonto keratoprosthesis. Therefore, a staged approach was pursued with (1) systemic methotrexate to control ocular surface inflammation, (2) minor salivary gland transplant to increase ocular surface lubrication, (3) lid margin mucous membrane graft to reduce keratinization, and finally, (4) Boston type 1 keratoprosthesis for visual restoration. After minor salivary gland transplant and mucous membrane graft, the Schirmer score improved from 0 mm to 3 mm with improvement in ocular surface keratinization. This approach successfully restored the vision to 20/60, and the patient has retained the keratoprosthesis for over 2 years. CONCLUSIONS: Sight restoration options are limited in patients with end-stage SJS with a keratinized ocular surface, aqueous and mucin deficiency, corneal opacification, and limbal stem cell deficiency. This case demonstrates successful ocular surface rehabilitation and vision restoration in such a patient through a multifaceted approach that resulted in successful implantation and retention of a Boston type 1 keratoprosthesis.

BACKGROUND: Polymorphous adenocarcinoma is the third most common malignant salivary gland tumor. Within polymorphous adenocarcinoma, cribriform adenocarcinoma of salivary glands is a rare subtype and resembles papillary thyroid carcinoma histopathologically. Diagnostically, cribriform adenocarcinoma of salivary glands is challenging for pathologists and surgeons alike as initial presentation and cytologic nuclear features can be easily confused with papillary thyroid carcinoma arising from a thyroglossal duct remnant or lingual thyroid. CASE PRESENTATION: A healthy 64-year-old Caucasian woman presented to a community otolaryngologist with a 4-year history of progressive postnasal drip, globus sensation, and eventual dysphonia. Flexible fiberoptic laryngoscopy showed a large, smooth, vallecular lesion filling the oropharynx. Computed tomography imaging of the neck showed a rounded heterogeneous mass centered within the right aspect of the oropharynx measuring 4.2 × 4.4 × 4.5 cm. Fine needle aspiration biopsy was suspicious for papillary carcinoma due to microscopic findings of malignant cells, nuclear grooves, and a powdery chromatin pattern. In the operating room, the tumor was resected en bloc using a lateral pharyngotomy approach with partial resection of the right lateral hyoid. A limited cervical lymphadenectomy was performed to facilitate the lateral pharyngotomy approach and two out of three lymph nodes demonstrated regional metastatic disease. Nuclear grooves, nuclear membrane notching, and occasional intranuclear pseudoinclusions were identified, which are overlapping histopathological characteristics of papillary thyroid carcinoma and cribriform adenocarcinoma of salivary glands. It was negative for thyroglobulin and thyroid transcription factor-1, which was in keeping with cribriform adenocarcinoma of salivary glands rather than papillary thyroid carcinoma. CONCLUSION: It is difficult to distinguish cribriform adenocarcinoma of salivary glands from papillary thyroid carcinoma solely by cytology, and the distinct characteristics of regional lymph node metastasis coupled with nuanced histologic differences should be emphasized in the evaluation of patients presenting with neck lymphadenopathy and an unknown primary or tongue mass. If sufficient fine needle aspiration biopsy material is available, thyroid transcription factor-1, thyroglobulin, or molecular testing may prove useful in differentiating cribriform adenocarcinoma of salivary glands from papillary thyroid carcinoma. A misdiagnosis of papillary thyroid carcinoma may lead to inappropriate treatment including unnecessary thyroidectomy. Therefore, it is critical for both pathologists and surgeons to be aware of this uncommon entity to avoid misdiagnosis and subsequent mismanagement.

PURPOSE: Consensus regarding whether elective neck dissection (END) provides better outcomes than observation in clinically node negative (cN0) minor salivary gland (MSG) carcinoma is lacking. Therefore, this study aimed to compare the impact of END with that of observation on regional control (RC) and overall survival (OS) and to detect the predictors for lymph-node metastasis in oral MSG carcinoma. PATIENTS AND METHODS: A single-institution, retrospective cohort study was designed; it included patients with cN0 oral MSG carcinoma treated at a tertiary teaching hospital between January 2002 and January 2022. The primary predictor variable was END and primary outcome variables were RC and OS. The secondary outcome variable was lymph-node metastasis. Other covariates included demographic and pathologic features, TNM stage, and adjuvant treatment. The Kaplan-Meier method and Cox proportional hazards model were used to determine the effect of END on RC and OS. The chi-squared test and logistic regression models were used to identify independent predictors for lymph-node metastasis. RESULTS: A total of 268 patients (107 men and 161 women) with a mean age of 46.4 ± 15.5 years were included. The 5-year RC rate was statistically different between the observation and END groups (75%; 95% confidence interval [CI], 67%-83; 95% CI, 81%-93%, respectively; P = .014). Cox regression analysis confirmed that END (hazard ratio [HR] 2.395; 95% CI: 1.433-8.275; P = .034) was independently associated with a decreased risk of regional recurrence. The 5-year OS rates for the observation and END groups were 66% (95% CI, 56-76%) and 76% (95% CI, 66-86%), respectively, and the difference was not statistical (P = .057). Occult metastasis occurred in 24.6% of patients. Primary tumor location on the tongue/floor of the mouth (odds ratio [OR], 4.287; 95% CI, 1.773-9.125; P = .011), T3/4 stage (OR, 3.286; 95% CI, 1.228-8.253; P = .021), and high-grade disease (OR, 6.674; 95% CI, 2.199-14.326; P < .001) were independently associated with an increased risk of occult metastasis. CONCLUSIONS: RC was better with END than with observation, but OS was comparable with the two approaches. Primary tumor location on tongue/floor of the mouth, T3/4 stage, and high-grade disease were associated with an increased risk of lymph-node metastasis.

Mucoepidermoid carcinoma (MEC) arising in pleomorphic adenoma (PA) is an extremely rare entity. Involvement of minor salivary glands by this entity has only being described twice previously. We report on a diagnostically challenging case in an 18 year old male with a large mass in the junction of the hard and soft palates that has been present for 12 months. Both cytology and incisional biopsy were inconclusive and indicated benign mixed tumour. Upon excision of the tumour with a 5 mm clear margin, histology demonstrated PA that has been replaced by small nests and cribriform islands of high-grade MEC with 13 mm of invasion beyond the original PA capsule. The tumour was composed of mostly intermediate-type cells with up to 7 mitoses per 10 high power fields. The tumour cells were positive for cytokeratin (CAM 5.2) and S100. Due to the high-grade nature and focal positive posterior margin of the resected specimen, adjuvant radiotherapy was administered. In conclusion, this case highlights the need to consider rare entities such as mucoepidermoid carcinoma ex pleomorphic adenoma in atypical cytological and histological findings. Moreover, it underlines the need to manage lesions with unconfirmed histological diagnosis with wide excision margins to avoid having involved margins post resection.

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 suitable methods for the the treatment of 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.

It is rare for intraductal papilloma, a benign papillary tumor, to occur in the salivary glands. To our knowledge, intraductal papilloma occurring in the minor salivary glands of the larynx has not been reported. In this report, we describe a case of intraductal papilloma that occurred in the minor salivary glands of the larynx. A woman in her 30s presented with hoarseness and dyspnea since a year. Fiber-optic laryngoscopy revealed a submucosal tumor involving the left aryepiglottic fold and the left false vocal fold. Computed tomography and magnetic resonance imaging revealed a 17 × 15 × 10 mm3 mass with homogenous isodensity, with regular, well-defined margins located on the left aryepiglottic fold and the left false vocal fold. Surgical resection was performed, and subsequently a diagnosis of intraductal papilloma was made by pathologic evaluation. During the follow-up period of over 3 years, the lesion has not recurred. In conclusion, intraductal papilloma of the minor salivary glands should be considered in the differential diagnosis of laryngeal submucosal tumors.

BACKGROUND: We investigate whether pathological continuous variables of lymph nodes were related with survival results of carcinomas of minor salivary gland carcinoma in head and neck. METHODS: Forty-four cases with minor salivary gland carcinoma who underwent both primary resection and neck dissection were retrospectively enrolled. The pathological continuous variables were evaluated by the number of positive lymph nodes, lymph node ratio, and log odds of positive lymph nodes. Receiver operating curve analysis was used for the cut-off values of the carcinoma-specific death. Log-rank test and Cox's proportional hazards model were used for uni-/multi-variate survival analyses adjusting for pathological stage, respectively. RESULTS: Lymph node ratio = 0.05 as well as log odds of positive lymph nodes = - 2.73 predicted the carcinoma-specific death. Both lymph node ratio and log odds of positive lymph nodes were significantly related with survival outcomes by the univariate analysis. Lymph node ratio ≥ 0.05 was associated with shorter disease-specific (hazard ratio = 7.90, 95% confidence interval = 1.54-57.1), disease-free (hazard ratio = 4.15, 95% confidence interval = 1.48-11.2) and overall (hazard ratio = 4.84, 95% confidence interval = 1.05-24.8) survival in the multivariate analysis. CONCLUSION: A higher lymph node ratio of minor salivary gland carcinoma is a predictor of shorter survival results.

BACKGROUND: Sublabial gland biopsy is the 'gold standard' in establishing the diagnosis of primary Sjögren's syndrome. Bleeding and nerve damage are complications. Our centre has adopted the use of the chalazion clamp to provide a dry surgical field to address these challenges. This study aimed to assess the accuracy of minor salivary gland harvest rate using this technique. METHOD: A retrospective review of all minor salivary gland biopsies was carried out in a single tertiary referral centre over a five-year period. RESULTS: Forty-one biopsy patients were identified, with a mean age of 56.1 years. There was 100 per cent accuracy in harvest rate in our series. Twelve patients (29 per cent) were positive for primary Sjögren's syndrome. No patients had a complication immediately or at one month follow up. CONCLUSION: Dry surgical field sublabial gland biopsy is a safe and highly effective technique in the diagnosis of primary Sjögren's syndrome. Initial results indicate it may provide a higher harvest rate with fewer complications than traditional non-ischaemic techniques.

We refer a case report of a canalicular adenoma of minor salivary gland, located at the submucosal region of the upper lip. The patients' clinical state was thoroughly studied, along with the histopathological findings. The surgical excision was the treatment of choice. Numerous histogenesis theories and the appropriate tumor treatment are mentioned, being always in accordance with the relative literature. Canalicular adenoma of minor salivary gland is a rare oral mucosa lesion. The differential diagnosis among many oral swellings is interesting. The surgical excision is the treatment of choice. The histological examination confirms the clinical diagnosis.

The aim of this study was to analyse the rates of metastatic events and clinical outcomes of patients with adenoid cystic carcinoma (ACC) of the minor salivary glands and to critically evaluate the role of surgical therapy. A retrospective cohort study was designed including all patients with ACC of the oral minor salivary glands treated in the study department during the years 2010-2017. Relevant clinicopathological data were analysed to determine factors with an impact on overall survival (OS) and progression-free survival (PFS). Forty-one patients with primary ACC of the oral cavity and the oropharynx were included. Cervical metastases were found in 14 patients (34.1%) and were shown to have a significant negative impact on OS (P=0.009) and PFS (P=0.03). Sixteen patients developed disease recurrence during follow-up (39.0%) and most patients exhibited local disease recurrence with or without regional or distant metastases (14/16, 87.5%). Local recurrence was treated successfully with surgery in five cases. We recommend surgical therapy for patients with ACC of the minor salivary glands, including elective neck dissection and microvascular reconstruction, to optimize the planning of adjuvant therapy.

BACKGROUND: Reconstruction of upper labial myomucosal defects is surgically challenging. AIMS: We evaluated whether central defects could be repaired using bilateral, buccinator myomucosal advancement flaps (b-BMAFs). METHODS: We evaluated five patients with early-stage, minor salivary gland mucoepidermoid carcinomas (low-grade [n = 2], intermediate-grade [n = 2], and high-grade [n = 1]) who underwent central, upper labial myomucosal reconstruction using b-BMAFs after cancer ablation. We treated two men and three women aged 25-59 years. Tumors ranged in size from 1.8 × 1.8 to 2.5 × 2.2 cm. Clinical stages were I and II in two and three patients, respectively. Defect dimensions ranged from 2.8 × 2.8 to 3.5 × 3.2 cm. RESULTS: All patients underwent successful reconstruction of central, upper labial myomucosal defects using b-BMAFs and were satisfied with the esthetic results. Adequate orbicularis oris and speech function were maintained. No reduction in mouth opening was observed. Patients were followed up for 24-36 months; one pulmonary metastasis was observed at 36 months postoperatively. CONCLUSION: Placement of b-BMAFs is safe and feasible when reconstructing central, upper labial myomucosal defects after ablation of early-stage, minor salivary gland cancer.

RATIONALE: Epithelial-myoepithelial carcinoma is an extremely rare, malignant neoplasm that occurs most frequently in the major salivary glands and accounts for approximately 1% of all salivary gland neoplasms. Few reports have described the presence of epithelial-myoepithelial carcinoma in the sinonasal region; hence, the treatment guideline and prognosis remain unclear. PATIENT CONCERNS: We reported a case of a 75-year-old woman with complaint of nasal obstruction and frequent epistaxis for 3 years. During the nasal endoscopic examination, a mass in the left nasal cavity originating from the left nasal septum that caused bleeding on touch was observed. DIAGNOSES: A diagnosis of epithelial-myoepithelial carcinoma was made based on the features of histopathology and immunohistochemistry of the surgical specimens. The patient was treated by surgical removal of the septal mass using the endonasal endoscopic approach. OUTCOMES: In the serial follow-up paranasal sinus imaging and endoscopic inspection, evidence of recurrence was absent for 18 months after surgery. LESSONS: This report highlights a case of epithelial-myoepithelial carcinoma originating from a minor salivary gland in the nasal septum, one of the most unusual locations. Diagnosis of epithelial-myoepithelial carcinoma should be made based on the findings of immunohistochemistry of the operative specimen. Clinicians should consider complete surgical resection as the effective treatment of choice.

OBJECTIVE: Polymorphous adenocarcinoma of salivary gland (PAC) is rare. Despite being described as a low risk histology, some patients develop regional and distant metastasis. More aggressive behavior has been attributed to a PAC subcategory called cribriform adenocarcinoma of minor salivary glands (CAMSG). We examined oncological outcomes of PAC. PATIENTS AND METHODS: Fifty-seven patients with PAC were identified from an institutional database of 884 patients surgically treated for salivary gland malignancies from 1985 to 2015. Detailed histopathological analysis was performed. Survival outcomes were calculated using the Kaplan-Meier method. Factors predictive of recurrence were identified using the Cox proportional hazard method. RESULTS: Fifty-four (95%) had tumors of minor salivary gland origin; the most frequent location was the oral cavity in 41 (76%), specifically the hard palate in 32 (55%). Forty-six patients (81%) were clinical T1-T2; 3 (5%) had a clinically positive neck. Thirty-two patients (56%) were classified as PAC and 14 (25%) as CAMSG. Forty-four patients (77%) had surgery alone; 13 (23%) had surgery and postoperative radiotherapy. The 5- and 10-year overall survival and disease-specific survival were 88% and 79% and 98% and 94%, respectively (median follow up 84 [1-159] months); 5- and 10-year recurrence-free survival were 93% and 88%, respectively. Univariate analysis showed male sex, III/IV stage, and CASMG variant had increased incidence of recurrence but were not statistically significant. CONCLUSION: PAC of the salivary glands is an indolent disease with good survival outcomes. Recurrence is uncommon and tends to occur late. Long-term follow-up is indicated in patients with this disease.

BACKGROUND: Minor salivary gland carcinomas of the head and neck are rare cancers with variable clinical behavior. This study explored the incidence, pathology, clinical behavior, and factors predictive of outcomes in a large cohort of patients treated at Memorial Sloan Kettering Cancer Center over a 30-year period (1985-2015). METHODS: Clinical, pathological, treatment, and outcome data were collected. Unadjusted and adjusted hazard ratios for each variable were calculated with univariate and multivariable Cox regression for survival and recurrence outcomes. RESULTS: Four hundred fifty patients were included: 55% were female, 56% were younger than 60 years, and the median follow-up was 74 months (range, 1-364 months). The most common site was the oral cavity with 305 tumors (68%), which was followed by the oropharynx with 96 (21%), the sinonasal cavity with 38 (8%), the trachea with 7 (2%), and the larynx with 4 (1%). The most common histological types were mucoepidermoid carcinoma (180 tumors [40%]), adenoid cystic carcinoma (141 tumors [31%]), and polymorphous low-grade adenocarcinoma (54 tumors [12%]). The 5-year predicted overall survival rate was 86%, and the disease-specific survival rate was 94% at 5 years. Pathology and tumor stage were significant variables on multivariate analysis for overall survival, disease-specific survival, recurrence-free survival, local recurrence-free survival, regional recurrence-free survival, and distant recurrence-free survival. CONCLUSIONS: American Joint Committee on Cancer stage and pathology were the most predictive variables across all outcomes. Tumor site, postoperative radiotherapy, and margin status were not statistically significant variables after tumor stage and pathology were controlled for in most outcomes.

BACKGROUND: Sjögren's syndrome is a rheumatological condition. Diagnosing Sjögren's syndrome can be challenging given the overlapping nature of clinical presentations. Currently, minor salivary gland biopsy is considered the definitive test for diagnosing Sjögren's syndrome. Various surgical techniques have been described, targeting biopsy of minor salivary glands from the lower lip. Identification of minor salivary glands is often difficult because of bleeding. One common complication of minor salivary gland biopsy is lip paraesthesia from iatrogenic sensory nerve injury. OBJECTIVES: To describe a minor salivary gland biopsy technique in a bloodless operative field using a chalazion ophthalmic clamp under local anaesthesia, and to report our clinical outcomes. METHODS: A prospective study was performed on patients who underwent minor salivary gland biopsy using a chalazion ophthalmic clamp between July 2017 and April 2018. RESULTS: The study included 23 patients. The histopathological reports positively identified minor salivary glands for all patients. In nine cases, the histological findings were positive for Sjögren's syndrome. No lip paraesthesia complications were reported post-operatively. CONCLUSION: This technique facilitates a superior yield, ensures adequate sampling of appropriate glands for histopathological analysis, and minimises the complications associated with traditional techniques.

BACKGROUND: Sialolithiasis is the most common disease of the salivary glands. Sialolithiasis usually develops in the major salivary glands, and rarely in the minor salivary glands, with only 2% of all cases of sialolithiasis occurring in the minor salivary glands and sublingual glands. Sialoliths in the minor salivary glands result in few or no clinical symptoms and are seldom identified on imaging. CASE PRESENTATION: We report herein our experience with a case of minor salivary gland sialolithiasis in a 67-year-old woman. On examination, an elastic soft, mobile, and well-circumscribed mass was palpable within the left upper lip. Ultrasound examination revealed a hypoechoic mass with heterogeneous internal echoes. The mass was excised under local anesthesia. Based on histopathological findings, a diagnosis of minor salivary gland sialolithiasis was established. CONCLUSIONS: Diagnosis of minor salivary gland sialolithiasis is challenging due to the difficulty of detecting sialoliths on imaging. A well-circumscribed mass was detected in the upper lip, and ultrasound examination revealed a round lesion, raising the suspicion of a benign tumor. Other diseases that can develop at the upper lip are calcified lymph node, phlebolith, fibroma, pleomorphic adenoma, myxoma, vascular malformation, salivary gland tumor, non-specific sialadenitis, and malignant tumor. Surgical excision is the favored approach for confirming a diagnosis of intramucosal nodular lesions.

OBJECTIVE: Necrotising Sialometaplasia is a benign self limiting reactive condition of major and minor salivary glands, which can arouse suspicion for malignancy, clinically and histopathologically. Here, we report a case of 38-year-old female with a painful ulcer on the palate. The case enlightens the importance of clinicopathologic correlation and diligent follow up in diagnosis and management of the case.
