Braz J Otorhinolaryngol 2024; 90:101462. [PMID: 38991401 PMCID: PMC11295561 DOI: 10.1016/j.bjorl.2024.101462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 05/19/2024] [Accepted: 06/20/2024] [Indexed: 07/13/2024] Open
Abstract
OBJECTIVE The aim of this retrospective article is to evaluate postoperative outcomes after extracapsular dissection for small benign superficial parotid neoplasms (<3 cm) in patients who received Superficial Musculoaponeurotic System (SMAS) flap and in patients who did not receive it. METHODS Two groups were created and statistically compared regarding Frey's syndrome and aesthetic satisfaction by data collected through the POI-8 validated questionnaire and through an aesthetic satisfaction scale ranging from 1 to 10. The difference between these two groups was the utilization of SMAS flap. SMAS flap was harvested in one of these two group, meanwhile was not used in the other. RESULTS The p-value analysis between group 1 and group 2 on these complications, resulted statistically not significant. Also, the aesthetic satisfaction resulted not statistically significant between group 1 and group 2. Gender, localization, and facial palsy resulted statistically correlated with the aesthetic satisfaction (p-value < 0.05). CONCLUSION In conclusion, there is no statistical difference in the use of SMAS flap for benign parotid neoformations of the superficial lobe, with a diameter of less than 3 cm for which extracapsular dissection is adopted as a surgical technique. LEVEL OF EVIDENCE: 3

Abstract
PURPOSE Pleomorphic adenoma (PA), the most common benign tumour of the parotid gland, requires accurate preoperative diagnosis owing to its capacity for malignant transformation. The aim of this study was to evaluate our experience with ultrasound-guided fine-needle aspiration biopsy (FNAB) in the diagnostic algorithm for patients with PA and to assess clinical outcomes for those with different surgical approaches. MATERIAL AND METHODS We carried out a retrospective analysis of patients treated for parotid gland mass between 2010 and 2016. These had had preoperative FNAB and had undergone subsequent surgery. RESULTS 165 patients had FNAB with the result of PA and the definitive histology confirmed PA in 159 cases (96.4%). On the other hand, in 179 patients, the definitive histology showed PA and the preoperative FNAB result corresponded in 159 cases (88.9%). The measured sensitivity, specificity and accuracy of ultrasound-guided FNAB in the diagnosis of PA were, respectively, 88.83%, 96.23% and 92.31%. Most of the patients underwent superficial or partial superficial parotidectomy, followed by extracapsular dissection which was associated with statistically lower risk of facial nerve injury (P=0.04). CONCLUSION Ultrasound-guided FNAB is simple, accurate and valuable in the diagnosis of PA and provides results that can lead to the choice of less invasive operative treatment.

The extracapsular dissection technique in the management of benign tumours of the parotid gland: our experience in 194 patients. J Laryngol Otol 2024; 138:565-569. [PMID: 37807905 PMCID: PMC11063660 DOI: 10.1017/s0022215123001767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 09/18/2023] [Accepted: 09/23/2023] [Indexed: 10/10/2023]
Abstract
OBJECTIVE The indications for and approaches to extracapsular dissection for parotid gland benign tumours are debated in the literature. This study retrospectively evaluates a single site's short- and long-term results with a standardised extracapsular dissection approach to benign parotid tumours. METHODS A retrospective review of a single institution's records identified cases with extracapsular dissection as the primary surgery for non-recurrent benign parotid tumours. A total of 194 eligible patients were identified (124 women and 70 men, age 47.75 ± 15.62 years). Pre-, intra- and post-surgical data were reviewed for complications and recurrences. RESULTS Histology reported pleomorphic adenoma in 165 patients, Warthin's tumour in 28 patients and both in one patient. Mean follow up was 36 ± 16 months (range, 12-84 months). The incidences of complications following extracapsular dissection were temporary (n = 13) and permanent (n = 0) facial nerve dysfunction, Frey's syndrome (n = 1)) and recurrences (n = 5). These rates align with prior literature. CONCLUSION This case series shows how a standardised approach to extracapsular dissection for benign parotid tumours yields favourable results, supporting a progressive change of strategy towards reduced invasiveness.

[PMID: 37191772 PMCID: PMC10914882 DOI: 10.1007/s10006-023-01156-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 05/07/2023] [Indexed: 05/17/2023]
Abstract
PURPOSE Warthin tumors (WT) are the second most common benign parotid gland neoplasms. They can occur as synchronous or metachronous lesions in 6-10% of cases. This study aims to compare the complication rate in 224 patients who underwent extracapsular dissection (ECD) or superficial parotidectomy (SP) for the treatment of a WT. METHODS This retrospective study was conducted at the Department of Maxillo-Facial Surgery at the University of Naples "Federico II" from February 2002 to December 2018 on a group of patients who underwent surgical treatment for WT. The type of surgical technique was chosen based on Quer's classification. The complications evaluated were facial nerve palsy, hematoma, Frey's syndrome, and bleeding. RESULTS A total of 224 patients treated from 2002 to 2018 for Warthin tumor were included in the study. Two hundred elven had solitary tumors (94.1%) and 13 had multicentric lesions (5.8%), of which 9 cases presented synchronous lesions and 4 cases presented metachronous lesions. Extracapsular dissection (ECD) was performed in 130 patients (58.3% of cases) and superficial parotidectomy (SP) in the other 94 (41.7% of cases). CONCLUSIONS We consider both surgical techniques as valid. In our opinion, it is essential to study each case based on Quer's Classification to obtain the best surgical outcome. Based on a lower observed rate of complications such as facial nerve palsy, Frey's syndrome, and bleeding, ECD seems to be the best option for the surgical treatment of Quer Class I lesions.

Abstract
Gland-preserving surgery has gained popularity for treating benign parotid tumors, offering potential benefits by preserving facial nerve function and salivary secretion while reducing complications. This study aims to evaluate the functional, cosmetic, and disease control outcomes of gland-preserving surgery via a postauricular sulcus incision. METHODS An observational longitudinal investigation encompassed 46 patients undergoing gland-preserving surgery for benign parotid tumors via the postauricular sulcus incision approach. Patient assessments included cosmetic contentment, functional repercussions, and disease management throughout the follow-up. RESULTS Predominantly, tumors were situated in the superficial lobe, with successful application observed in 8 instances (17%) within the deep lobe. Notably, no tumor recurrences were detected during the follow-up period. Postoperative pain remained minimal, accentuated by high patient satisfaction regarding the incision scar and facial symmetry. Furthermore, preservation of facial nerve functionality and salivary secretion was observed. CONCLUSION Gland-preserving surgery via the postauricular sulcus incision technique exemplifies advantageous functional and cosmetic outcomes when addressing benign parotid tumors. This approach presents a secure and efficient alternative, facilitating effective local management.

Abstract
OBJECTIVES Surgical management of parotid pleomorphic adenoma ranges from total parotidectomy to extracapsular dissection (ECD). Minimalistic techniques aim to preserve function and minimize the rate of recurrence. This study assesses functional, aesthetic, and disease control outcomes post-ECD through a sole transverse cervical incision for parotid pleomorphic adenoma. MATERIALS AND METHODS This longitudinal analysis enrolled 36 consecutive patients with pleomorphic adenoma who underwent ECD via a single cervical incision. Complications, satisfaction, salivary function, and tumor recurrence were evaluated. Salivary gland function was assessed using scintigraphy at 6 months post-surgery. RESULTS Tumors occurred in superficial (83%) or deep (17%) parotid inferior parts according to the European Salivary Gland Society level classification. The median tumor size was 2.8 cm (1.8-6.0 cm); the median operation time was 42 min (30-65 min). No tumor spillage or facial nerve injuries occurred. Facial nerve paralysis was only temporary in two (6%) patients, with minimal other complications. Operated parotid gland function matched the unoperated side. No recurrence was found during the median follow-up of 44 months (24-60 months). CONCLUSIONS ECD via a single transverse cervical incision is a safe approach for benign parotid tumors, yielding excellent functional and disease control outcomes. CLINICAL RELEVANCE These findings can provide clinically meaningful minimally invasive recommendations to treat pleomorphic adenoma with minimal complications.

Abstract
Gallstone disease (GD) is one of the most common morbidities in the world. Laparoscopic Cholecystectomy (LC) is currently the gold standard, performed in about 96% of cases. The most affected groups are the elderly, who generally have higher pre- and post-operative morbidity and mortality rates and longer Length of Stay (LOS). For this reason, several indicators have been defined to improve quality and efficiency and contain costs. In this study, data from patients who underwent LC at the "San Giovanni di Dio e Ruggi d'Aragona" University Hospital of Salerno in the years 2010-2020 were processed using a Multiple Linear Regression (MLR) model and Classification algorithms in order to identify the variables that most influence LOS. The results of the 2352 patients analyzed showed that pre-operative LOS and Age were the independent variables that most affected LOS. In particular, MLR model had a R2 value equal to 0.537 and the best classification algorithm, Decision Tree, had an accuracy greater than 83%. In conclusion, both the MLR model and the classification algorithms produced significant results that could provide important support in the management of this healthcare process.

Abstract
Background Incision scars and postoperative cosmesis are critical in the management of benign parotid tumors. Traditional incisions have a typical visible scar in the retromandibular area or require wide skin flaps. Purpose In this study, we introduced a new surgical approach called the tri-split flap approach and evaluated its technical feasibility and surgical outcomes. Materials and Methods Eleven patients with clinically benign parotid gland tumors underwent the tri-split flap approach and were followed for six to ten months postoperatively. Facial weakness, salivary fistula formation, first bite syndrome, earlobe numbness, and the subjective cosmetic results were evaluated. Results All tumors were completely excised, and the patients were highly satisfied with the esthetic outcome of the surgery. No patients developed wound dehiscence, facial nerve injury, or first bite syndrome during the follow-up period. One patient developed a minor salivary fistula that resolved after three weeks. Conclusion The tri-split flap approach not only provides adequate exposure of the surgical site to achieve complete resection of benign parotid gland neoplasms but also results in a very short and highly concealed post-operative scar. This technique is a potential surgical approach in parotidectomy. Supplementary Information The online version contains supplementary material available at 10.1007/s12663-021-01605-1.

Abstract
The aim of the present study was to analyze the clinical characteristics, surgical treatments and clinical outcome of patients with parotid gland tumors and to compare the results with those cited in the literature. A retrospective study was conducted in 140 patients (male, n=77; female, n=63) with parotid gland tumors who underwent parotidectomy at Hokuto Hospital Department of Otolaryngology-Head and Neck Surgery (Obihiro, Japan) between April 2007 and December 2021. Of the 140 patients enrolled, 118 (84.3%) patients had benign tumors, including 63 (45%) patients with pleomorphic adenomas and 43 (30.7%) patients with Warthin tumors, and 22 patients (15.7%) had parotid carcinoma. Comparison of the three groups of patients with parotid gland tumors indicated that pack years as an indicator of smoking status were significantly higher in patients with Warthin tumors than in those with parotid carcinomas (P=0.011) or pleomorphic adenoma (P<0.001). Fine-needle aspiration cytology (FNAC) was non-diagnostic for only 6 (4.3%) of 140 patients. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of FNAC by both conventional smear and liquid-based cytology (LBC) for parotid carcinomas were 70, 99, 93.3, 94.4 and 82.9%, respectively. Among the 22 patients with parotid carcinoma, extended total/total and superficial parotidectomy were performed in 10 (45%) and 11 (50%) cases, respectively. Total and selective neck dissection of the area from level II to I, II and III were performed in 6 (24%) and 7 (32%) patients, respectively. Postoperative radiotherapy (50 Gy) was performed in 15 (68%) patients. The overall survival (OS) and disease-free survival (DFS) rates at 5 years were 51.5 and 76.4%, respectively. Univariate analysis revealed that age >65 years was significantly associated with poorer 5-year OS (P<0.001) and DFS (P<0.001). Multivariate analysis revealed that an age of more than 65 years combined with high-grade histologic malignancy was associated with worse DFS (P=0.02; hazard ratio, 3.628; 95% confidence interval, 1.283-9.514). In conclusion, the clinical characteristics and treatment outcomes of parotid gland tumors were consistent with the results of previous reports. Smoking may be closely related to the pathogenesis of Warthin tumors. LBC potentially provides improved accuracy in FNAC.

Abstract
BACKGROUND This study evaluated functional and disease control outcomes after gland-preserving surgery via a single transverse cervical incision for Warthin's tumor of the parotid gland. METHODS One-hundred eleven patients with Warthin's tumor underwent the preservation of most normal parotid tissues and the facial nerve combined with the en-bloc resection of tumors. Postoperative complications, subjective satisfaction, salivary function, and metachronous tumor were assessed in each patient. RESULTS No patients had an extension to modified Blair or periauricular incision with the median operation time of 32 min. Temporary and permanent paralysis of the facial nerve was 5 (4.0%) and none of 125 tumor resection sides, respectively. Postoperative complications were minimal. The secretory functions between the affected and unaffected glands did not differ. One patient had metachronous tumor for a median follow-up of 72 months. CONCLUSION Functional gland-preserving surgery via single transverse cervical incision can safely treat Warthin's tumor in the parotid gland.

Abstract
ABSTRACT The correct surgical approach to benign parotid gland tumors is still matter of debate, it should be chosen considering the possibility of local recurrence or facial nerve complications in case of "not necessary" facial nerve dissection. In the era of minimally invasive surgery, more sparing approaches such as extracapsular dissection or partial superficial parotidectomy (PSP) are gaining popularity. The aim of the study is to present surgical results and long-term outcomes of PSP (level I or II) in a large group of patients. Six hundred fifty-one patients who underwent parotid surgery between 2004 and 2020 were initially considered. Five hundred forty patients with benign lesions treated with PSP, enucleation, ECD were enrolled. Clinical features, surgical data, postoperative scarring, seroma, dehiscence, neuroma, outcomes as Frey syndrome, and delayed facial nerve dysfunction have been evaluated. 65.5% PSP, 25.2% enucleation, and 9.2% extracapsular dissection. No statistical difference in surgical time has been found (P 0.16). P > 0.05 for seroma, neuroma, Frey syndrome, and facial palsy between different type of surgery. Frey syndrome in PSP: 6/135 (4.4%) in 2004 to 2012 and 2/219 (0.9%) in 2013 to 2020. The reduction between periods is significant (P < 0.04). Recurrence: 0.8% (3/354) for PSP patients, 3.4% (5/136) in enucleation and 10% (5/50) in ECD (P = 0.02). Partial superficial parotidectomy can be considered a minimally invasive and quick procedure with low complication rate. Our data seem to support this statement (large case series and long-term follow-up).

Abstract
INTRODUCTION Gland-preserving surgery is often used for benign tumours in the parotid gland. Partial superficial parotidectomy via a periauricular incision may bring satisfactory cosmetic outcomes but the disease control outcome remains unrevealed. This study evaluated functional and disease control outcomes after gland-preserving surgery via periauricular incision for pleomorphic adenoma of the parotid gland. METHODS This longitudinal study included 248 consecutive patients with parotid pleomorphic adenoma who underwent the preservation of most normal parotid tissues and the facial nerve combined with the en-bloc resection of tumours via periauricular incision. Postoperative complications, subjective satisfaction, salivary function, and tumour recurrence were assessed in each patient. The secretory function of the salivary gland was measured using salivary scintigraphy at 6 months after surgery, and ultrasonography was regularly followed. RESULTS Median tumour size was 2.5 cm (range, 0.8-5.2 cm) and median operation time was 55 min (range, 39-88 min). All tumours were safely removed by gland-preserving surgery via periauricular incision without extension to Blair or hairline incision and tumour spillage. Temporary and permanent paralysis of the facial nerve was 14 (5.6%) and none of the study patients, respectively. Postoperative complications were minor and Frey's syndrome was found in 6 (2.4%) patients. The Secretary function of the affected gland was equal to that of the unaffected gland. No patients had a recurrence for a median follow-up of 78 months (range, 24-126 months). CONCLUSIONS Functional gland-preserving surgery via periauricular incision can treat pleomorphic adenoma in the parotid gland with satisfactory functional, cosmetic, and disease control outcomes.

Head Neck 2021; 43:3631-3645. [PMID: 34288212 DOI: 10.1002/hed.26813] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 06/29/2021] [Accepted: 07/08/2021] [Indexed: 12/16/2022] Open
Abstract
The impact of the extent of parotid surgery on postoperative complications has long been considered a topic of controversy. The aim of the current network meta-analysis (NMA) is to answer the following questions: (1) Does the extent of surgical resection of benign parotid tumors increase the risk of postoperative complications? (2) What is the best surgical intervention for treatment of benign parotid tumors that can provide an acceptable balance between tumor recurrence rate and other postoperative complications? A comprehensive search on PubMed, Embase, Scopus, and Cochrane library was conducted to identify the eligible studies. The outcome was the incidence of tumor recurrence, facial nerve weakness (temporary [TFW] or permanent [PFP]), Frey's syndrome (FS), sialocele, and salivary fistula. The Bayesian network meta-analysis (NMA) accompanied by a random effect model and 95% credible intervals (CrI) were calculated using the GeMTC R package. Forty-four studies with a total of 7841 participants were included in the current NMA comparing five surgical interventions, namely enucleation, extracapsular dissection (ECD), partial superficial parotidectomy (PSP), superficial parotidectomy (SP), and total parotidectomy (TP). Enucleation showed the highest recurrence rate compared to ECD, SPS, SP, and TP. No statistical differences were observed concerning the recurrence rate when ECD, PSP, SP, and TP were compared together. There was an increased incidence of TFW and FS with the increase in the extent of parotid resection, while no significant difference was found when comparing enucleation with ECD and PSP. SP showed the highest incidence of PFP, and salivary fistula compared to ECD, PSP, and TP. The tumor recurrence rates in enucleation, ECD, PSP, SP, and TP were 14.3%, 3.6%, 3.7%, 2.8%, and 1.4%, respectively. The current NMA demonstrated that the risk of TFW and FS increases with the increase in the extent of parotid resection and that ECD and PSP can be considered the treatment of choice for benign parotid tumors, as both provide an acceptable balance between the incidence of tumor recurrence and facial nerve dysfunction.

Abstract
Salivary gland tumors are relatively uncommon with most being benign. When diagnosed the most common benign and malignant tumors are pleomorphic adenoma and mucoepidermoid carcinoma (MEC), respectively. However, not uncommonly, it is difficult to differentiate between the histopathological entities, leading to a diagnostic dilemma that can impact a patient’s treatment and prognosis. A 24-year-old woman presented with a three-year history of asymptomatic left-sided facial swelling. She denied any prior history of head and neck radiation. There was no history of alcohol consumption or smoking exposure and there was no personal or family history of head and neck cancers. Additionally, she did not have any known occupational or environmental exposures. Due to the chronicity and painless nature of this facial mass, our patient did not pursue evaluation initially. Subsequently, she experienced an increase in size and pain for a few months exacerbated by swallowing. She had no other symptoms. On physical examination, a 3 x 3 cm left parotid gland mass was noted. There was no associated head or neck lymphadenopathy and compression of the left facial mass did not elicit secretions from the opening of Stensen’s duct. Due to the rapid increase in size, she was sent for CT neck/soft tissue with contrast which confirmed a 3.56 x 2.67 cm solid nodule within the superficial portion of the left parotid gland. This was followed by an MRI orbit/face/neck with and without contrast, for further delineation, which demonstrated a 4 x 3.7 x 3 cm complex heterogeneous mass within the superficial left parotid gland. Thereafter the patient underwent an uncomplicated ultrasound-guided biopsy of the parotid mass. The histopathological appraisal concluded that this was a cellular pleomorphic adenoma, with mucinous and squamous metaplasia with reactive lymph nodes. Due to the new rapid increase in size and intense painful nature of this tumor, nerve-sparing left parotidectomy, fat grafting and reconstruction were completed. Cellular pleomorphic adenomas are benign low-grade neoplasms, typified as biphasic with both epithelial and myoepithelial components. However, they have increased cellularity and focally increased mitotic activity, not advanced enough to qualify as malignant. The presence of mucinous and squamous metaplasia is of diagnostic interest as it makes diagnosis on fine-needle aspiration (FNA) morphologically challenging. These findings are typical of MEC and on FNA can be misleading in the setting of a pleomorphic adenoma. However, on histopathological evaluation of the gross specimen along with immunohistochemical staining the diagnosis is made much easier. A diagnosis of MEC would have potentially required neck dissection and adjuvant therapy with a potential increased risk of morbidity and mortality. This case emphasises the importance of an adequate tissue biopsy in regards to parotid gland tumors to optimise a patient's care plan.

Abstract
The transmandibular route is often combined with the transparotid-transcervical approach when extensive surgical field exposure is required, as in the case of deep parotid lobe tumors measuring over 4 cm in size. This procedure implies great morbidity and prolongs surgery time. Furthermore, in cases where additional lip division is performed, the aesthetic outcomes may be poorer. A description is made of the technique used for the removal of giant pleomorphic adenomas of the parapharyngeal space, without mandibulotomy. Key words:Parapharyngeal space tumor, pleomorphic adenoma, transcervical-transparotid approach, transmandibular approach.

Abstract
Introduction: Parotid pleomorphic adenoma (PPA) is the most common benign salivary gland neoplasm. Extracapsular dissection (ED) arose as a conservative surgical technique alternative to superficial parotidectomy to reduce complications. Materials and Methods: Patients who underwent ED for superficial, <3 cm, mobile parotid lumps (Quer I) between 2004 and 2008 were retrospectively analysed focusing on those with histological diagnosis of pleomorphic adenoma. A retrospective cohort study on 50 patients who accepted to undergo ultrasonography and clinical evaluation for at least 10 years since surgery was performed. Clinical data, surgical reports, and validated questionnaires for the assessment of complications, quality of life (QoL) and aesthetic satisfaction were analysed. Recurrence rate and complications after ED, with their QoL and aesthetic impact, were evaluated. Statistical analysis was performed setting α=0.05 as the level of significance. Results: Low occurrence of complications related to ED was seen. Overall QoL after ED was very good (range 1–7, mean 6,86), due to low complications incidence of complications and their low severity, as assessed by patients through Parotidectomy Outcome Inventory-8 questionnaire. Overall aesthetic satisfaction was high (range 1–10, mean 9,78). Aesthetic satisfaction and QoL was statistically related to onset of complications (P = 0.02504 and P = 0.001859). Tumour localization and dimension was not statistically related to onset of complications (P = 0.8207 and 0.7586). After a mean follow-up of 12.5 years, no recurrences were detected. Discussion: There is a lack of studies with a long-term follow-up after ED for the evaluation of recurrences and complications. Considering our results, the ED technique should be adopted as the first surgical approach for Quer I PPA without suspicion of malignancy.

Giant Parotid Pleomorphic Adenoma with Atypical Histological Presentation and Long-Term Recurrence-Free Follow-Up after Surgery: A Case Report and Review of the Literature. Case Rep Dent 2020; 2020:8828775. [PMID: 32953184 PMCID: PMC7481918 DOI: 10.1155/2020/8828775] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 08/14/2020] [Accepted: 08/21/2020] [Indexed: 11/17/2022] Open
Abstract
Salivary gland tumors (SGT) comprise 3% of all head and neck tumors, are mostly benign, and arise frequently in the parotid gland. Pleomorphic adenoma (PA) is the commonest SGT, representing 60-70% of all benign parotid tumors. Clinically, parotid PA presents as irregular, lobulated, asymptomatic, slow-growing preauricular mass, involving both superficial and deep lobes, and could grow to gigantic proportions. Histologically, PA has epithelial and mesenchymal elements in chondromyxoid matrix and is managed surgically. Based on a review of 43 cases reported in English literature since 1995, giant parotid PA is reported as large as 35 cm (diameter) and 7.3 kg (resected weight). Although rare, 10 cases of malignant transformation were reported in the review. Surgical management included extracapsular dissection (ECD), superficial parotidectomy, and total parotidectomy for benign tumors, and adjuvant radiation or chemotherapy for malignant tumors. We further present the case of a 36-year-old healthy male with slow-growing and asymptomatic giant parotid PA, of 4-year duration. The patient presented with firm, lobulated preauricular swelling, provisionally diagnosed as PA based on radiographic and cytological findings. The tumor was resected through ECD, and the patient had uneventful postoperative recovery and a 7-year recurrence-free follow-up period. Histological examination revealed epimyoepithelial proliferation punctuated by chondromyxoid areas, with extensive squamous metaplasia and keratin cysts. To the best of knowledge from indexed literature, giant parotid PA is rarely reported in Saudi Arabia. In addition to its rarity, this case is reported for its benign nature despite atypical histological presentation, successful surgical management without complications, and long-term recurrence-free follow-up. Based on this report, clinicians must be aware of atypical histological presentations associated with PA and plan suitable surgical management and follow-up to avoid morbidity. Nevertheless, attempts must be made to diagnose and manage these lesions at an early stage and before they reach gigantic proportions.
