Desafío diagnóstico y terapéutico de carcinoma mucoepidermoide palatino: reporte de un caso

Resumen Las neoplasias en glándulas salivales son infrecuentes, representando menos del 3% de los tumores de cabeza y cuello. El carcinoma mucoepidermoide es el tumor maligno más común en glándulas salivales, siendo su principal ubicación la parótida. Clínicamente se asemeja a otras lesiones de mucosa oral, por lo cual, es importante realizar un correcto diagnóstico diferencial. Su comportamiento biológico se relaciona con el grado histológico tumoral, factor relevante en el pronóstico y tratamiento de esta neoplasia. Presentamos el caso de un paciente hombre de 75 años afectado con un tumor en paladar con diagnóstico de carcinoma mucoepidermoide de bajo grado. Como tratamiento se realizó una maxilectomía parcial y una placa obturadora en base a una prótesis removible y posterior reconstrucción con un colgajo libre microvascularizado. Actualmente el paciente se encuentra en controles periódicos, libre de enfermedad. Los tumores de glándulas salivales son un desafío diagnóstico, requieren de exámenes imagenológicos y del estudio histopatológico. Cuando existen dudas en el diagnóstico, se debe considerar repetir la toma de la muestra o la obtención de biopsias de más de una zona representativa que permita el diagnóstico de la lesión.

Abstract Salivary gland neoplasms are infrequent lesions representing less than 3% of head and neck tumors. Mucoepidermoid carcinoma is the most common malignant tumor in salivary glands, being the parotid the most usual location. Clinically, it resembles other oral mucosa lesions, therefore, it is important to make a correct differential diagnosis. Its biological behavior is related to the tumor histological grade, a relevant factor in the prognosis and treatment of this neoplasm. We reported a case of a 75-year-old-man, with a tumor in the palate, diagnosed as low-grade mucoepidermoid carcinoma. A partial maxillectomy and an obturator plate were performed based on a removable prosthesis and subsequent reconstruction with a microvascularized free flap. The patient is currently undergoing regular checkups, maintaining disease free. Salivary gland tumors are a diagnostic challenge, requiring imaging tests and histopathological study. In case of doubts with the diagnosis, it should be considered to biopsy more than area or to repeat the biopsy in order to obtain a representative sample that allows the diagnosis of the lesion.

Unusual treatment of pleomorphic adenoma of soft palate in adult / Tratamiento inusual del adenoma pleomórfico del paladar blando en adulto

Pleomorphic adenoma is the most common benign neoplasia of the salivary glands and affects mostly the parotid gland, less frequently the minor salivary glands. Minor salivary gland tumors have a higher risk of malignancy compared to tumors of the major salivary glands, so appropriate diagnostic evaluation should be prompt. In this case report, we present a case of an extensive pleomorphic adenoma of soft palate in an adult patient. After preoperative investigation using Fine Needle Aspiration (FNA) and imaging tests, the patient was successfully treated by surgical resection under general anesthesia. There was no recurrence seen after a follow-up period of 1 year.

El adenoma pleomórfico es la neoplasia benigna más común de las glándulas salivales y afecta principalmente la glándula parótida, con menos frecuencia en las glándulas salivales menores. Los tumores de las glándulas salivales menores tienen un mayor riesgo de malignidad en comparación con los tumores de las glándulas salivales mayores, por lo que la evaluación diagnóstica apropiada debe ser rápida. En este reporte de caso, presentamos un caso de un extenso adenoma pleomórfico de paladar blando en un paciente adulto. Después de la investigación preoperatoria utilizando aspiración con aguja fina y pruebas de imagen, el paciente fue tratado con éxito con la resección quirúrgica bajo anestesia general. No se observó recurrencia después de un período de seguimiento de 1 año.

Prospective phase Ⅱ study of postoperative concurrent chemoradiotherapy for patients with high-risk malignant salivary gland tumors / 中华放射肿瘤学杂志

Objective To assess the efficacy and safety of post operative adjuvant concurrent chemoradiotherapy for patients with high-risk salivary gland tumors (SGT).Methods Fifty-two patients with moderate or high malignant pathological stage complicated with locally advanced stage Ⅲ/ⅣA±positive margin/close margin admitted to Shanghai Ninth People's Hospital from 2016 to 2018 were enrolled in this study.Among them,35 patients were male and 17 female with a median age of 55.5 years old (range:21-73 years old).All 52 patients were treated with intensity-modulated radiotherapy and concurrent chemotherapy.Patients with adeno carcinoma of the salivary gland receives concurrent chemotherapy with TP regimen.Patients with lympho epithelial cancer and squamous cell carcinoma were treated with cisplatin regimen.Results Forty-seven patients (90％) completed two cycles of concurrent chemotherapy,and five patients (10％) completed one cycle of concurrent chemotherapy.The median follow-up time was 15.7 months (3.2-34.8 months).The 2-year disease-free survival (DFS) and overall survival (OS) rates were 74％ and 98％.Three patients experienced regional lymph recurrence and 6 cases had distant metastasis.Grade Ⅲ oral mucositis was observed in 30 patients.Grade Ⅲ dermatitis occurred in 5 cases.Only one patient experienced Grade Ⅳ neutropenia,and 2 patients developed Grade Ⅲ neutropenia.DFS was positively correlated with the cycle of postoperative adjuvant concurrent chemotherapy (P=0.006).Conclusions Patients with high-risk SGT can obtain higher 2-year DFS and OS rates and tolerable adverse events after postoperative concurrent chemoradiotherapy.Nevertheless,the long-term outcomes remain to be validated by randomized controlled clinical trials.

Pleomorphic Adenoma of a Minor Salivary Gland of the Hard Palate Report of a Case

The pleomorphic adenoma is the most common benign tumor of the minor salivary glands and is comprised of epithelial and mesenchymal tissues. The majority of the salivary gland tumors occur in the second decadeof life with a slight predilection for females. Clinically it presents as a firm or rubbery submucosal mass without ulceration or surrounding inflammation. Diagnosis is established on the clinical examination and histopathology, supplemented with plane radiographs, computerized tomography, and magnetic resonance imaging when necessary. Here, we report a case of pleomorphic adenoma of the hard palate in a 21-year-old female patient with a painless swelling in the left palatal region of nine months duration.

Sialoadenite esclerosante crônica em glândula salivar menor / Chronic sclerosing sialoadenitis in small salivary gland

A sialoadenite esclerosante crônica, também conhecida como tumor de Kutner, é uma condição, que acomete, predominantemente, glândulas salivares maiores. Clinicamente, apresenta-se como um nódulo, móvel, assintomático e de consistência endurecida. Seu diagnóstico definitivo só é conseguido através da análise histopatológica onde estão presentes: intenso infiltrado inflamatório linfocítico, atrofia acinar, fibrose do parênquima glandular e graus variáveis de esclerose. Neste artigo, é relatado um caso clínico raro de sialoadenite esclerosante crônica, localizada em glândula salivar menor... (AU)

Chronic sclerosing sialoadenitis, also known as Kutner's tumor, is a condition that predominantly affects major salivary glands. Clinically it presents as a nodule, mobile, asymptomatic, and of hardened consistency. Its definitive diagnosis is only achieved through the histopathological analysis where they are present: intense lymphocytic inflammatory infiltrate, acinar atrophy, fibrosis of the glandular parenchyma and variable degrees of sclerosis.

Sclerosing polycystic adenosis of the parotid gland: a case report and literature review / 口腔疾病防治

Objective @#To explore the clinicopathological features, diagnosis, treatment and prognosis of sclerosing polycystic adenosis (SPA) and provide a reference for clinics.@*Methods @#A case of sclerosing polycystic adenosis of the parotid glands was retrospectively analyzed, and the relevant literature was reviewed.@*Results @# A 57-year-old female patient presented with a tumor, which she had noticed for half a month, on the left side of the lower ear, with occasional paroxysmal numbness and no complaint of other discomfort. Resection of the left submandibular area tumor was performed, and the tumor specimen pathological results showed sclerosing polycystic adenosis of the left parotid gland, with no recurrence after six-months follow-up. Sclerosing polycystic adenosis is rare, occurs in the parotid gland and is characterized by a frequently painless, slow-growing mass of the parotid gland. Imaging examination and fine needle aspiration biopsy can only be used as a reference; the diagnosis must include a pathology examination. Histological manifestations showed that abundant sclerotic collagenous stroma was permeated by ductal and acinar lobules, and cystic dilatation of the duct was accompanied by epithelial hyperplasia and diverse ductal cells. Immunohistochemistry of the ductal and acinar cells showed positive expression of cytokeratin (AE1-3 and CAM5.2) and S100 protein. The ducts filled with hyperplastic and dysplastic epithelium were surrounded by an intact myoepithelial layer that was positive for SMA, p63, and calponin, with a Ki-67 index less than 3%. Treatment comprised mainly surgical resection, with a good prognosis. However, one-third of cases relapse: low-grade malignant tumors may occur, with at least one report of invasive cancer.@*Conclusion@#Sclerosing polycystic adenosis of the salivary gland is rare and has a good prognosis, but patients may relapse easily after surgery. The diagnosis depends primarily on pathological examination. The main treatment is surgical resection, the prognosis is good, and follow-up should be strengthened after surgery.

Myxoma arising from the parotid gland

Myxomas can be divided into two groups: those derived from the facial skeleton, and those derived from external skeletal soft tissue. Soft tissue myxomas of the head and neck are uncommon, with fewer than 50 cases reported. In any form and location, myxoma of parotid gland is rare. We report a case of myxoma arising from the left superficial lobe of the parotid gland with good long-term follow-up after superficial parotidectomy with tumor excision. A 49-year-old man was referred to our department of plastic and reconstructive surgery with a painless palpable mass that had persisted in the left mandible angle region for 2 years. Excision of the facial mass and superficial parotidectomy with facial nerve preservation were performed. The biopsy result was myxoma. Long-term follow-up for 22 months showed favorable results without evidence of recurrence but with temporary facial nerve weakness right after the surgery. Myxoma should be considered as a differential diagnosis when benign tumor of the parotid gland is being considered.

Adenoid cystic carcinoma of the hard palate presenting as ipsilateral sixth nerve palsy

Adenoid cystic carcinoma (ACC) is an uncommon malignant neoplasm composed of basaloid epithelial and myoepithelial cells. The palate is the most commonly involved intraoral site for ACC. Here, we document the case of an advanced ACC arising from the hard palate that presented with right-sided sixth nerve palsy in a 75-year-old male with no other systemic illnesses. ACC of the head and neck involving the cavernous sinus and presenting as isolated sixth nerve palsy is exceedingly rare. In the absence of vasculopathic or ischemic risk factors, regardless of the age of the patient; neuroimaging should be performed in cases of isolated nontraumatic sixth nerve palsy.

Comparison of microRNA profiles between benign and malignant salivary gland tumors in tissue, blood and saliva samples: a prospective, case-control study / Comparação de perfis de microRNA entre tumores de glândula salivar benignos emalignos em amostras de tecido, sangue e saliva: estudo caso-controle prospectivo

Abstract Introduction: Salivary gland tumors (SGTs) are rare head and neck malignancies consisting of a spectrum of tumors with different biological behaviors. Objective: In this study we aimed to find out differential expression of microRNA profiles between benign and malignant SGTs. Methods: We investigated the possible role of 95 microRNAs in the 20 patients with salivary gland tumors with comparison of 17 patients without malignancy or salivary gland diseases. Sixteen of the tumors were benign (seven pleomorphic adenomas, nine Warthin tumors), four of them were malignant (two squamous cell carcinomas, one high grade mucoepidermoid carcinoma, one adenocarcinoma). Serum and saliva samples were collected from both patients and control group. Tissue samples of tumor masses were also collected from patient group. Results: Among studied microRNAs miR-21, miR-23a, miR-27a, miR-223, miR-125b, miR-126, miR-146a, miR-30e were down regulated in the benign group compared to control group in the serum samples (p-values are 0.04, 0.00005, 0.00005, 0.0022, 0.031, 0.00008, 0.044, and 0.0007, respectively). When tissue samples were studied miR-21, miR-31, miR-199a-5p, miR-146b, miR-345 were up-regulated in the malignant group compared to benign group (p values are 0.006, 0.02, 0.013, 0.013, 0.041, respectively). miR-30e showed statistically significant up-regulation in malignant tumor group's plasma samples compared to benign group (p = 0.034). There was no statistically significant difference in saliva samples between groups. Conclusion: Our results showed that different microRNAs may play role in salivary tumor pathogenesis according to biological behavior. Although there was no difference in saliva samples between groups, according to tissue and serum samples miR-21 and 30e may have an important role; since they were down-regulated in benign tumors whereas up-regulated in malignant ones.

Quando as amostras de tecido foram estudadas,miR-21, o miR-31, o miR-199-5p, miR-146b, o miR-345 foram suprarregulados no grupo malignoem relação ao grupo benigno (valores de p são 0,006, 0,02, 0,013, 0,013, 0,041, respectiva-mente). O miR-30e apresentou suprarregulação estatisticamente significativa em amostras deplasma do grupo de tumor maligno em relação ao grupo benigno (p = 0,034). Não houve diferençaestatisticamente significativa em amostras de saliva entre os grupos. Conclusão: Nossos resultados mostraram que diferentes microRNA podem desempenhar umpapel na patogenia do tumor salivar de acordo com o comportamento biológico. Embora nãotenha havido diferença em amostras de saliva entre os grupos, de acordo com as amostras detecido e de soro, miR-21 e 30e podem ter um papel importante, já que foram infrarreguladosnos tumores benignos enquanto suprarregulados nos tumores malignos.

Adenoid cystic carcinoma in maxillary antrum – A rare presentation

Adenoid Cystic Carcinoma is a rare malignant salivary gland tumor comprising <1% of all malignancies of head and neck and 10-15 % of the malignant tumors of salivary glands. Most of it arises in minor salivary glands nearly about 60%. Intraorally, about 50% of adenoid cystic carcinomas occur in the palate. Here by, we present a case of adenoid cystic carcinoma affecting the left maxillary antrum and palate on the same side in 30 years old male along with a brief review of literature.

Evaluation of salivary gland tumors by ultrasonography and CT-scan.

Introduction: Salivary gland tumor is a tumor that forms in tissues of a salivary gland. Salivary gland cancer is rare, with 2% of head and neck tumors forming in the salivary glands, the majority in the parotid. Ulttrasonography plays a very significant role in the diagnosis and management of salivary gland lesions. CT scan is useful for evaluating intra glandular component of mass. Aim and objectives: To study the appearances of salivary gland tumors including major and minor salivary glands using radiological modalities like: Ultra-sonography, CT-SCAN, MRI to diagnosis and evaluate salivary gland tumors in order to do early management of the condition. Materials and methods: 30 cases of either strong suspicion or symptoms related to salivary glands were evaluated who came to Dhiraj Hospital with different radiological modalities like Ultrasonography, CT-SCAN. Results: Out of total number of 30 patients who were diagnosed and evaluated for salivary gland tumor on Ultrasonography , CT SCAN are conditions like: Warthin’s Tumor, Pleomorphic adenoma, Mucoepidermoid Carcinoma, Lipoma, Rhabdomyosarcoma, Sialolithiasis in Submandibular gland, Lymphoma parotid and some other conditions related to major and minor saliary glands tumors. Conclusion: Ultrasound and CT scan are both comparable in their ability to diagnose Salivary gland tumors. Although Ultrasound has a slightly inferior specificity rate as compared to CT scan, but it is still a very compelling option for the initial imaging of the Salivary gland tumors. CT scan is useful for evaluating intra glandular component of mass especially in deep lobe of parotid, mass extending to para-pharyngeal space that is inaccessible to ultrasound

Adenoma pleomórfico gigante en paladar. Reporte de caso y revisión de la literatura / Giant pleomorphic adenoma of the palate. Case report and literature review

Resumen: El adenoma pleomórfico es considerado el tumor benigno más frecuente de las glándulas salivales y se caracteriza histológicamente por presentar tanto elementos epiteliales como mesenquimales. El presente estudio tiene como objetivo reportar un caso clínico de adenoma pleomórfico en paladar de grandes dimensiones de un paciente masculino de 45 años de edad, tratado en la Unidad de Cirugía Buco-Maxilofacial del Hospital General del Este «Dr. Domingo Luciani¼ quien inicia enfermedad actual, hace 17 años aproximadamente presentando un aumento de volumen progresivo en paladar. Se planificó quirúrgicamente para una maxilectomía de Brown tipo II B y colocación de placa obturadora. En un control postoperatorio de 10 meses se evidenció formación de tejido en la región del lecho quirúrgico de aspecto similar a la mucosa circundante sin señales de recidiva con presencia de fístula oro-nasal de aproximadamente 2 cm de diámetro. Actualmente se encuentra en programación de cierre de la misma con colgajos locales y posterior rehabilitación protésica.

Abstract: Pleomorphic adenoma is considered the most frequent benign tumor found in the salivary glands. Histologically it is characterized by presenting epithelial as well as mesenchymal elements. The present study targets the report of a clinical case of a large size pleomorphic adenoma found in a 45 year old patient. The patient was treated at the Oral and Maxillofacial Surgery Unit of the Eastern General Hospital «Dr. Domingo Luciani¼. The patient reported onset of the disease approximately 17 years before, with a progressive volume increase in the palate. A surgical Brown type II B maxillectomy was planned, with placement of a shutter plate. At a 10 month post-surgery control, tissue formation was observed in the region of the surgical bed, this formation exhibited similar appearance to the surrounding mucosa, with no signs of recurrence and presence of an oral-nasal fistula measuring approximately 2 cm in diameter. Presently, the patient is programmed to receive a fistula closure procedure by means of local flaps as well as subsequent prosthetic rehabilitation.

Recurrent Pleomorphic Adenoma of the Parotid Gland

Pleomorphic adenoma is the most common type of salivary gland tumor and the most common tumor of the parotid gland. Because of its propensity for invasion, pleomorphic adenoma of the parotid requires superficial parotidectomy or total parotidectomy to minimize the risk of tumor recurrence. We report a case of pleomorphic adenoma of the parotid gland with repeated recurrences. A 23-year-old male patient presented with a protruding neck mass. Six years prior to this presentation, the patient had undergone superficial parotidectomy for the removal of pleomorphic adenoma of the right parotid gland at our institution. The patient experienced recurrence at 17 months after the initial resection, which required a total parotidectomy with partial resection of the facial nerve. Pathologic examination revealed histologic findings consistent with pleomorphic adenoma across the surgical specimen from all three of the operations. The patient suffered from facial nerve paralysis, with facial expressions partially recovered over a year.

Adenoid cystic carcinoma of the parotid gland – A case report and review of literature.

Adenoid cystic carcinoma (ADCC) is a relatively rare malignant salivary gland tumor comprising less than 1% of all malignancies of head and neck. It can arise in any salivary gland site, but approximately 50–60% develops within the minor salivary glands. On fine needle aspiration cytology FNAC), hyaline globules surrounded by neoplastic cells forming a cell ball are the diagnostic. Adenoid cystic carcinoma, being rare, was not suspected at the first instance. The final diagnosis was made from the cytological, radiological, and histopathological reports.

Pleomorphic Adenoma with Predominant Myoepithelial Cells of the Hard Palate: Reconstruction with Pedicled Buccal Pad of Fat – A Case Report.

Pleomorphic adenoma is a mixed tumor of salivary gland origin presenting frequently in major salivary glands and sporadically in minor salivary glands. It is a benign tumor with both epithelial and mesenchymal tissues. Salivary glands in general may present with a diverse range of lesions posing a challenge to even the most experienced clinician. Resection with surrounding dispensable normal tissues is the key to successful management of such tumors. This case report illustrates an enormous pleomorphic adenoma of minor salivary gland in the hard palate of 10 years duration.

Adenoid cystic carcinoma arising from minor salivary glands of palate involving maxillary sinus.

Adenoid cystic carcinoma (ACC) was first described by Billroth in 1856 and was called ‘cylindroma’ due to its characteristic histological appearance. ACC is the most common malignant neoplasm of the lacrimal gland, and the second most common type of carcinoma arising in the salivary glands, following mucoepidermoid carcinoma. Palate is the most commonly affected site followed by parotid gland, submandibular gland, antrum & tongue. Characteristic features include aggressive, slow growth, with insidious destruction of surrounding tissues, perineural invasion, prolonged clinical course and the tendency for delayed onset of the distant metastases which worsens the prognosis. Long term survival can be achieved particularly with combined surgery and radiotherapy. The most common pattern is the cribriform architecture. Histopathology is the gold standard for the diagnosis of ACC. CT & MRI are considered to be of almost similar significance in detection of perineural spread with preference to MRI because of its high soft tissue contrast. Here we have mentioned a case of Adenoid Cystic carcinoma arising from minor salivary glands of palate.

Myoepithelial carcinoma of palate: Case report.

Myoepithelial carcinoma is an uncommon malignant salivary gland neoplasm with a predilection for parotid gland. However, its occurrence in minor salivary glands is considerably less with only 28 cases being reported in the literature. We report a case of myoepithelial carcinoma of palate in a 50-year-old woman. Computed tomography and magnetic resonance imaging revealed an extensive lesion in the palate. Microscopically, the tumor exhibited a wide spectrum of cytomorphologic features that overlap with other salivary gland tumors. Immunohistochemistry served as an adjunct in the diagnosis of the lesion. Clinical, radiographic, and histopathologic correlation along with immunohistochemical profi le enabled to arrive at a diagnosis of myoepithelial carcinoma.

Histogenesis of salivary gland neoplasms.

Salivary gland tumors are one of the most complex and relatively rare group of lesions encountered in oral pathology practice. Their complexity is attributed to heterogeneity of the cells of origin of these lesions. The problem is compounded by the ability of these cells to differentiate and modify into various morphological subtypes resulting in a myraid of histomorphological patterns. This also leads to a frequent overlap of microscopic features among various neoplasms and sometimes even between benign and malignant lesions causing significant diagnostic dilemma which sometimes may even not be resolved by immunohistochemical studies. Despite this the knowledge of histogenesis and morhogenetic concepts of salivary gland tumorigenesis greatly helps the pathologist in classifying these lesions as well as determining the prognosis. It will also help in development of newer strategies for differentiating these lesions and making an early diagnosis. The present article is aimed at reviewing and summarizing the current concepts regarding the histogenesis of salivary gland tumors and their relevance to routine diagnosis and classification of these lesions.

Pleomorphic Adenoma: A Case Report and Review of Literature / Adenoma Pleomórfico: Reporte de Caso y Revisión de la Literature

Pleomorphic adenoma, the most common salivary gland tumor, consists of epithelial and mesenchymal components. Its morphologic complexity results from differentiation of tumor cells into fibrous, hyalinized, myxoid, chondroid and osseous areas. The diagnosis is made by the clinical and histo pathological examination. The treatment of pleomorphic adenoma is surgical excision. Malignant transformation, though rare, has been reported. In this article, we report a case of pleomorphic adenoma with literature review.

El adenoma pleomórfico es el tumor más frecuente de las glándulas salivales, con componentes epiteliales y mesenquimales. Su complejidad morfológica es resultado de la diferenciación de las células tumorales en las zonas fibrosas, hialinizadas, mixoides, condroides y óseas. El diagnóstico se realiza mediante el examen clínico e histopatológico. El tratamiento de adenoma pleomórfico es la escisión quirúrgica. La transformación maligna, aunque rara, ha sido reportada. En este artículo se presenta un caso de adenoma pleomórfico con revisión de la literatura.

Carcinoma adenoquístico de glándula sublingual. A propósito de un caso / Adenocystic carcinoma of the sublingual gland. On the purpose of a case

Los tumores de glándulas salivales son relativamente infrecuentes, constituyendo el 1% de los tumores de cabeza y cuello, siendo aún más raros los tumores de glándulas sublinguales, aunque frecuentemente su diagnóstico es maligno. El propósito de este trabajo es la presentación de un caso clínico que presentó un carcinoma adenoquístico de glándula sublingual en suelo de boca lado izquierdo. Clínicamente apareció una lesión alargada, sobre el trayecto del conducto de Wharton, con una coloración normal, lisa, brillante y asintomática. Se le realizó exéresis simple de la lesión y el Departamento de Anatomía Patológica confirmó el diagnóstico. Se procedió a revisar la bibliografía nacional e internacional sobre estas lesiones encontrándose escasas referencias debido a su rareza. La evolución de la paciente después de 16 meses ha sido satisfactoria.

The salivary gland tumors are relatively infrequent, being only 1 % of the head and neck tumors; the sublingual gland tumors are even more unusual, although their diagnosis is frequently malignant. The purpose of the current work is presenting a clinical case carrying a sublingual gland adenocystic carcinoma on the left side of the mouth bottom. Clinically, there it was a long lesion, over the course of the Wharton’s duct, with an asymptomatic, normal, brilliant and smooth color. The lesion was simply removed and the Department of Pathologic Anatomy confirmed the diagnosis. We reviewed the national and international literature on these lesions, finding scarce references because of its unusualness. The patient’s evolution is satisfactory when 16 months have passed from the surgery.
