summaRyThe objective of this study was to describe the rare thyroid MALT lymphoma concomitant with papillary thyroid carcinoma in a male patient who was submitted to total thyroidectomy. Treatment and follow-up issues are addressed. Male patient complains of fast thyroid enlargement without lymphadenophaty and normal clinical exams. Total thyroidectomy was indicated and performed without any complications. The pathology showed multicentric papillary thyroid carcinoma, concomitant thyroid MALT lymphoma and Hashimoto's thyroiditis. The immunohistochemistry assay was positive for CD 20, CD 43, CD 79, AE1/AE3. The staging studies showed no evidence of both metastasis, Ann Harbor stage IE, without B symptoms. After RIT no further radiotherapy or chemotherapy was indicated. Nowadays the thyroglobulin is undetectable, without recurrences at two years of follow-up. It was concluded that primary thyroid MALT lymphoma is uncommon being the papillary thyroid carcinoma more frequent. Both occurring concomitantly is very rare and the treatment has to prioritize the tumor of worst prognosis at the discovery moment.

O tratamento e o seguimento são discutidos no texto. Paciente masculino com rápido aumento da tireoide sem linfonodomegalias com exames normais. A tireoidectomia total foi indicada e realizada sem complicações. O anatomopatológico mostrou carcinoma papilífero multicêntrico concomitante com linfoma MALT e tireoidite de Hashimoto. A imuno-histoquímica foi positiva para CD 20, CD 43, CD 79, AE1/AE3. O estadiamento clínico não demonstrou evidência de metástases de ambos, Ann Harbor estádio IE, sem sintomas B. Realizado RIT sem radioterapia ou quimioterapia. Atualmente se encontra com tireoglobulina indetectável, sem recidivas ao seguimento de dois anos. Concluiu-se que o linfoma MALT primário de tireoide é raro e o carcinoma papilífero é o mais frequente com boa evolução. A concomitância de ambos é muito rara e o tratamento deve priorizar a neoplasia que apresenta o pior prognóstico no momento da descoberta.
CONTEXT: Thyroglossal duct cysts are the most common congenital cervical abnormality in childhood. Malignant lesions are rare in thyroglossal duct cysts (about 1%). OBJECTIVE: To report a case of papillary carcinoma in thyroglossal duct cysts. DESIGN: Case report. CASE REPORT: The patient was a 21-year-old female with a four-month history of an anterior midline neck mass but without other symptoms. The physical examination revealed a 4.0 cm diameter, smooth, painless, cystic nodule at the level of the hyoid bone. The thyroid gland was normal by palpation and no neck lymph nodes were found. Indirect laryngoscopy, fineneedle biopsy aspiration and cervical ultrasound were normal and compatible with the physical findings of a thyroglossal duct cyst. The patient underwent surgery with this diagnosis, under general anesthesia, and the mass was resected by the usual Sistrunk procedure. There were no local signs of invasion of the tissue surrounding the cyst or duct at surgery. The patient was discharged within 24 hours. Histopathological examination of the specimen showed a 3.5 x 3.0 x 3.0 cm thyroglossal cyst, partially filled by a solid 1.0 x 0.5 cm brownish tissue. Histological sections showed a papillary carcinoma in the thyroid tissue of a thyroglossal cyst, with normal thyroid tissue at the boundary of the carcinoma. There was no capsule invasion and the margins were negative. The follow-up of the patient consisted of head and neck examinations, ultrasonography of the surgical region and thyroid, and total body scintigraphy. The patient has been followed up for two years with no further evidence of disease.
RESUMO As neoplasias das glândulas salivares são relativamente raras, compreendendo cerca de 1% das neoplasias de todo corpo, com incidência de 1/100.000 habitantes por ano. As neoplasias benignas predominam sobre as malignas. O prognóstico depende muito do tipo histológico, grau de diferenciação, localização, infiltração de tecidos vizinhos e da presença de metástases regionais ou a distância. O principal tratamento ainda é a cirurgia, com os seus desafios e dificuldades, devido aos ramos do nervo facial nas glândulas salivares maiores, seguido de radioterapia e em casos selecionados quimioterapia adjuvante. O objetivo desta revisão é fornecer ao leitor uma abordagem histórica sobre o tratamento das doenças das glândulas salivares, com especial atenção às doenças da glândula parótida assim como peculiaridades associadas aqueles que as estudaram ao longo da história.
Objective Goiters and benign nodules detected in the thyroid are growing lesions and the COVID-19 pandemic have negatively impacted on their surgical treatment. The appropriate selection of patients to treatment will improve the overall health status. This article review will focus on the impact of the COVID-19 pandemic on treatment of benign conditions of the thyroid gland and their implications. Methods This review pointed out the status of the health system in developing country and the problems to treat benign surgical diseases of thyroid. Aspects of epidemiology, incidence, clinical presentation and surgical treatment of goiters, economic and health status impact were cited. Results All surgical treatment of goiter and other benign conditions were postponed, forced to redirect, and reschedule all benign surgeries, situation aggravated by poor public management and closure of hospital beds. These conditions have caused deterioration in patients’ physical (decompensated thyroid disease) and mental health status, increasing work disabilities and burdening society by increasing the social and health cost. The overall situation could be catastrophic in emergent countries where this increased disease-related social expenditure on surgical treatment may increase the risk of national impoverishment as increase the treatment cost. Brazilian Society Head and Neck Surgery related some recommendations and new suggestions were made to safely treat these high potential hazard surgical conditions. Conclusions Surgeries for goiter and benign thyroid conditions can be performed during the COVID-19 pandemic, following strict safety protocols for the patient and the medical team, reducing the negative economic and on patient health impact.
Background The symptomatic (swelling and pain) salivary gland obstructions are caused by sialolithiasis and salivary duct stenosis, negatively affecting quality of life (QOL), with almost all candidates for clinical measures and minimally invasive sialendoscopy. The impact of sialendoscopy treatment on the QOL has been little addressed nowadays. The objective is to prospectively evaluate the impact of sialendoscopy on the quality of life of patients undergoing sialendoscopy due to benign salivary obstructive diseases, measured through QOL questionnaires of xerostomia degree, the oral health impact profile and post sialendoscopy satisfaction questionnaires. Result 37 sialendoscopies were included, most young female; there were 64.5% sialolithiasis and 35.4% post-radioiodine; with 4.5 times/week painful swelling symptoms and 23.5 months symptom duration. The pre- and post-sialendoscopy VAS values were: 7.42 to 1.29 (p < 0.001); 86.5% and 89.2% were subjected to sialendoscopy alone and endoscopic dilatation respectively; 80.6% reported improved symptoms after sialendoscopy in the sialolithiasis clinic (p < 0.001). The physical pain and psychological discomfort domain scores were mostly impacted where sialendoscopy provided relief and improvement (p < 0.001). We found a positive correlation between sialendoscopy and obstructive stone disease (p < 0.001) and no correlation in sialendoscopy satisfaction in xerostomia patients (p = 0.009). Conclusions We found improved symptoms with overall good satisfaction after sialendoscopy correlated with stones; and a negative correlation between xerostomia. Our findings support the evident indication of sialendoscopy for obstructive sialolithiasis with a positive impact on QOL and probably a relative time-dependent indication for stenosis/other xerostomia causes that little improved QOL satisfaction. Level of evidence 2b—Prospective non-randomized study. Trial registration: WHO Universal Trial Number (UTN): U1111-1247-7028; Brazilian Clinical Trials Registry (ReBeC): RBR-6p8zfs.
CONTEXT: Neuroglial ectopia has been defined as a mass composed of differentiated neuroectodermal tissue isolated from the spinal canal or cranial cavity and remains rare. This lesion has to be considered in the differential diagnosis among newborn infants with classical symptoms of respiratory distress, neck mass and feeding difficulties. We present a rare case of extensive parapharyngeal and skull base neuroglial ectopia in 6-month-old girl who presented respiratory and feeding obstruction at birth. CASE REPORT:A six-month-old girl who presented upper respiratory and feeding obstruction at birth and was using tracheostomy and gastrostomy tubes was referred to our institution. Complete surgical excision of the mass consisted of a transcervical-transparotid approach with extension to the infratemporal fossa by means of a lateral transzygomatic incision, allowing preservation of all vital neurovascular structures. The anatomopathological examination showed a solid mass with nests of neural tissue, with some neurons embedded in poorly encapsulated fibrovascular stroma, without mitotic areas, and with presence of functioning choroid plexus in the immunohistochemistry assay. Neurovascular function was preserved, thus allowing postoperative decannulation and oral feeding. Despite the large size of the mass, the child has completed one year and six months of follow-up without complications or recurrence. Neuroglial ectopia needs to be considered in diagnosing airway obstruction among newborns. Surgical treatment is the best choice and should be performed on clinically stable patients. An algorithm to guide the differential diagnosis and improve the treatment was proposed. RESUMOCONTEXTO: Tecido neuroglial ectópico é definido como uma massa composta de tecido neuroectodermal diferenciado, isolado do canal espinhal ou da cavidade craniana e permanece raro. Esta lesão tem de fazer parte do diagnóstico diferencial em neonatos com os clássicos sintomas de obstrução respiratória, massa cervical e dificuldade para alimentação. Descreve-se um raro caso de tecido neuroglial ectópico extensor em parafaringe e base de crânio em uma menina de seis meses de idade que apresentou os sintomas de obstrução respiratória e alimentar ao nascimento. RELATO DE CASO:Menina de seis meses de idade que apresentou obstrução respiratória alta e alimentar ao nascimento, usando traqueostomia e gastrostomia, foi encaminha à instituição. A ressecção cirúrgica completa da massa utilizou um acesso transcervical-transparotídeo com extensão para fossa infratemporal pela incisão lateral transzigomática, permitindo identificação e preservação das estruturas neurovasculares vitais. O exame anatomopatológico evidenciou uma massa sólida com ninhos de tecido neuronal com alguns neurônios imersos em estroma fibrovascular, de pouca cápsula, sem áreas de mitoses e presença de plexo coroide funcionante ao exame imunoistoquímico. As funções neurovasculares foram preservadas na cirurgia, permitindo a decanulação e alimentação via oral no pós-operatório. Ape...
PURPOSE:The parotidectomy technique still has an elevated paresis and paralysis index, lowering patient life's quality. The correct identification of the facial nerve can prevent nerve damage. Fluorescent dye identifies nerves in experimental studies but only few articles focused its use on facial nerve study in parotidectomies. We aimed to stain the rat facial nerve with fluorescent dye to facilitate visualization and dissection in order to prevent injuries. METHODS:Forty adult male Wistar rats were submitted to facial injection of saline solution (Gsf-control group, 10) or fluorescent dye solution (Gdye group, 30) followed by parotidectomy preserving the facial nerve, measuring the time for localization and facility of localization (LocTime and LFN). Nerve function was assessed using the Vibrissae Movements (PMV) and Eyelid Closure Motion (PFP) scores. RESULTS:Nerve localization was faster in Gdye group, with 83% Easy LFN rate. The Gdye group presented with low nerve injury degree and better PMV and PFP scores, with high sensitivity and accuracy. CONCLUSIONS:This experimental method of facial nerve fluorescence was effective for intraoperative nerve visualization, identification and preservation. The technique may be used in future facial nerve studies, translated to humans, contributing to the optimization of parotid surgery in the near future.
