RESUMO

Benign and malign tumors can affect the temporomandibular joint (TMJ) as any other articulation. Nevertheless, TMJ tumors are rare and mostly benign. Their clinical expression is varied including symptomatology similar to TMJ dysfunctional disorders, otologic or neurologic pathologies. In some cases, they remain totally asymptomatic. Hence, diagnosis is difficult since the symptomatology can be misleading with TMJ dysfunctional disorders or otologic disorders wrongly diagnosed. There is thus frequently a long delay between symptoms onset and diagnosis. The great variety of TMJ lesions explains the wide range of possible treatment modalities, mostly based on surgery. We provide here a review of the lesions originating from the TMJ. Tumoral or cystic mandibular lesion affecting the TMJ through local extension will not be discussed. Osteoma, osteoid osteoma, osteoblastoma, chondroma, osteochondroma, chondroblastoma, tenosynovial giant cell tumors, giant cell lesions, non-ossifying fibroma, hemangioma, lipoma or Langerhans cell histiocytosis are all possible diagnosis among the benign tumors found in the TMJ. Pseudotumors include synovial chondromatosis and aneurysmal bone cyst. Finally, malign tumors of the TMJ include mainly sarcomas (osteosarcoma, chondrosarcoma, synovial sarcoma, Ewing sarcoma, and fibrosarcoma), but also multiple myeloma and secondary metastases. We will review the clinical, radiological and histological aspects of each of these lesions. The treatment and the recurrence risk will also be discussed.

RESUMO

RATIONALE: Adult intussusception is rarely observed, accounting for about 5% of all cases of intussusception. Most ileal lipomas are asymptomatic and do not need any special treatment. Herein, we describe a case with ileocolic intussusception caused by ileal lipoma. PATIENT CONCERNS: A 27-year-old woman complaints of intermittent abdominal pain for 10 days. DIAGNOSIS: Abdominal computed tomography demonstrated ileocolic intussusception. Colonoscopy revealed a spherical polypoid lesion with surface capillary rising from the lateral wall of the ileum. A diagnosis of ileocolic intussusception was made. INTERVENTIONS: The patient underwent primary resection of the intussuscepted intestine after which an end-to-end anastomosis was performed. OUTCOMES: Histopathology report confirmed a 4.5 cm × 3.5 cm lipoma in the terminal ileum. The patient was discharged on a postoperative day 9 without complications. LESSONS: We describe the difficulties in diagnosis and treatment of this rare cause of intussusception and review the literature on adult intussusceptions. The ileal lipoma is a very rare cause of ileocolic intussusception. Abdominal CT and colonoscopy are important for the diagnosis of intussusception and abdominal lipomas. Surgical resection remains the treatment of choice.

RESUMO

CASE PRESENTATION: The patient was a 72-year-old man who consulted with his previous physician for chief complaints of palpitations, fatigue, and blackish feces persisting for 1 month. After confirming the presence of anemia, the patient was referred to our hospital. Blood test findings upon hospital arrival revealed a hemoglobin (Hb) level of 6.0 g/dL. Computed tomography revealed a tumor of 32 mm × 30 mm with a low-density area extending from the bulb to the second part of the duodenum. Magnetic resonance imaging revealed high signal intensity on T1- and T2-weighted imaging and low signal intensity on fat-suppressed T2-weighted imaging, findings consistent with lipoma. Upper gastrointestinal endoscopy revealed a yellowish submucosal tumor that had perforated into the intestinal tract from the external wall extending from the upper corner to the second part of the duodenum. After determining that the tumor was sessile, laparoscopic partial duodenectomy with Roux-en-Y reconstruction was planned and performed. Pathology revealed a yellowish tumor 4 cm × 4 cm in size extending from the pyloric area to the duodenal bulb arising from the tunica muscularis. The present case report details our experience involving a patient who underwent surgical resection for hemorrhagic duodenal lipoma.

RESUMO

BACKGROUND AND AIMS: Lipomatous hypertrophy of the interatrial septum is an uncommon type of cardiac adipose tumor. It is extremely rare for these lesions to be located in the interventricular septum. METHODS: We report this case of incidentally diagnosed lipomatous hypertrophy of the interventricular septum with right ventricular outflow obstruction which caused minimal symptoms and Wolff-Parkinson-White pattern on EKG. CONCLUSION: We also discuss the diagnosis and management of this condition.

RESUMO

AIM: To determine the clinical and radiographical aspects of six patients diagnosed with pericallosal lipomas (PCL). MATERIAL AND METHODS: A retrospective analysis of patients who presented to the neurosurgery outpatient clinics of Selcuk Faculty of Medicine between 2009 and 2019, revealed that six patients were diagnosed with PCL. The clinical and magnetic resonance imaging (MRI) data were obtained by reviewing patients? records. RESULTS: A total of six patients (two girls and four boys), with a mean age of 53.8 months (38?72 months), were included in this study. They were followed up for a mean period of 36.5 months (32?41 months). PCL were detected on MRIs, which were obtained to investigate headache in two patients, epilepsy in one patient, frontal dermal sinus tract and left frontal epidermoid tumor in one patient, and subcutaneous lipoma associated with PCL in one patient. Five patients displayed tubulonodular lipomas and one patient displayed curvilinear lipomas. Agenesis or dysgenesis of the corpus callosum (CC) was observed in four (66%) patients. Two patients received surgical treatment for cosmetic skin problem. CONCLUSION: Because of the benign course of PCL, i.e. no growth or very slow growth, and close proximity to the surrounding neurovascular structures, surgical removal should be considered only in symptomatic PCL. Furthermore, other malformations and anomalies may accompany PCL.

RESUMO

Lipomas are common benign mesenchymal tumors that originate from mature adipocytes throughout the body, with 13-20% occurring in the head and neck region, however only 1-4.4% affect the oral cavity, where they are found predominately in the cheek, followed by the tongue, lips, palatal mucosa, gingiva, and floor of the mouth. Herein, we present a multimedia analysis of transoral floor of mouth lipoma resection in a 58-year-old female. Learning points include (1) Identification and stenting of Wharton's ducts in order to facilitate their functional preservation and to minimize risk of postoperative sialocele; (2) postoperative observation with airway monitoring due to expected floor of mouth edema; (3) utilization of a midline incision to minimize injury to Wharton's ducts and maximize bilateral access to the floor of mouth.

RESUMO

RATIONALE: Lipomas are common benign tumors, constituting 16% of soft tissue mesenchymal tumors. They usually occur under the skin or in the large muscles of the thigh, shoulder, or upper arm. There are few reported cases of lipomas located in the forearm and hand muscles, accounting for less than 1% of all lipomas. PATIENT CONCERNS: A 47-year old man presented with a history of swelling and accompanying pain in the left wrist for 2 years. DIAGNOSES: The patient was diagnosed with intramuscular lipoma in the pronator quadratus. INTERVENTIONS: The mass was resected completely with wide-awake technique. OUTCOMES: The patient was followed up for 2 years with no recurrence. The symptoms of swelling and pain resolved within 3 weeks post-surgery, and there was no clear abnormality in wrist and finger movement and sensation. A satisfactory outcome was achieved. LESSONS: Intramuscular lipoma in the pronator quadratus is a rare benign tumor which should be distinguished from malignant tumors. Especially for patients with carpal tunnel syndrome presenting with wrist swelling, ultrasound, computed tomography, or magnetic resonance imaging can be used to assess deep tissue masses.

RESUMO

RATIONALE: Thyroglossal duct cyst (TGDC), the most common midline neck mass, has several histological diagnoses other than cyst in the literature. We present the first case of thyroglossal duct lipoma. PATIENT CONCERNS: A 63-year-old woman presented with a painless soft midline neck mass for more than 3 years, which enlarged in size and caused a lump sensation during swallowing. DIAGNOSES: Sonography revealed a 3.5 × 3.0 × 3.0-cm homogenous isoechoic oval lesion without an acoustic shadow beyond the thyroid glands. An ultrasound-guided biopsy revealed abundant sheets of fat cells with infiltration of some lymphocytes and histiocytes. Computed tomography revealed a 3.5 × 3.0 × 3.0-cm well-circumscribed ovoid mass with Hounsfield unit (HU) between -50 and -100 and a thyroglossal duct remnant. All these findings supported the diagnosis of thyroglossal duct lipoma. INTERVENTIONS: The patient underwent Sistrunk operation for excision of the neck tumor, and pathological examination revealed an adipose tumor surrounded by benign thyroid tissue, confirming the diagnosis of thyroglossal duct lipoma. OUTCOMES: Neither postoperative complication nor recurrence was noted at the 18-month follow-up. LESSONS: This is the first case of thyroglossal duct lipoma in the literature. Our study extends the disease spectrum of thyroglossal duct mass and suggests that clinicians should consider thyroglossal duct lipoma in the differential diagnosis of a midline neck mass.

RESUMO

Although the vast majority of soft tissue extremity masses are benign, approximately 13,000 people in the United States were diagnosed with soft tissue sarcoma in 2019. This article focuses on the optimal workup of soft tissue masses including the indications for ultrasound and MRI, as well as use of preoperative core needle biopsy. Current AJCC staging, surgical principles of soft tissue sarcoma management, and data regarding indications for radiation therapy and chemotherapy are reviewed. As up to 50% of patients with soft tissue sarcoma will develop recurrent disease, surgical management of locally recurrent and distant metastatic disease is discussed.

RESUMO

Background: Lipomas are rarely seen tumors of adipose tissue that are benign in character. Although mostly located to the subcutaneous region, specifically in the upper back, neck, and shoulder, they may also occur in thoracic cavity. Aim: They aim of the study was to analyse clinical features and outcome of treatment of intrathoracic pleural lipomas. Materials and Method: We retrospectively evaluated the clinicopathological records of seven patients with intrathoracic lipomas who had undergone surgery between 2005 and 2017. We made analyses in terms of age, gender, admission complaints, lesion locations and dimensions, diagnostic techniques, operative procedures, histopathological features, and prognosis. Results: Four women and three men with a mean age 62.7 (range, 48-75 years) were included. They had chest pain (n = 2), effort dyspnea (n = 1) as the admission symptom, whereas four patients were asymptomatic, whose lesions were detected on chest radiography on an incidental basis. The radiological features of the tumors were well-demarcated, homogenous lesions with fat density. Tumors of all cases were excised, which were located on the right side in two patients and left in five. We used video-assisted thoracoscopy in two patients, single-port video-assisted thoracoscopy in three patients, thoracotomy in two patients. All lesions were of parietal pleural origin and were located intrathoracically. They had a range of size between 4 and 10 cm, with an average of 6.7 cm. All cases were operated with complete resection. At a mean follow-up duration of 4.7 years no recurrence was noted. Conclusion: Intrathoracic lipomas are rare, benignly behaving tumors. As it may prove difficult to differentiate them from malignant lesions and they may grow in an invasive growth pattern, surgery should be pursued in all patients for both diagnosis and treatment.

RESUMO

Giant lipomas are rarely found in the head and neck region. A 67-year-old male patient presented with a massive ventral swelling of his neck extending from the lower margin of the mandible to the clavicle. The mass had slowly grown over 20 years without causing any symptoms, except for considerable psychological stress because of the disfiguration of the patient's profile appearance. Contrast magnetic resonance imaging suggested a lipomatous soft tissue lesion. The surgically removed tumor measured 32 × 20 × 4 cm. Surgery was completed without any intraoperative complications or injury to the critical structures of the neck. The patient was satisfied with the cosmetic result of the operation, and histopathological examination confirmed a lipoma.

RESUMO

BACKGROUND: Adipose lesions of nerve are generally distinguished as either extraneural or intraneural lipomas or, alternatively, lipomatosis of nerve. We present a patient with an unusual circumferential lipoma that completely encircles the right sciatic nerve and discuss a possible pathogenesis. CASE DESCRIPTION: A 44-year-old woman presented with progressive symptoms and signs of sciatic neuropathy for 1 year. Magnetic resonance imaging revealed a large lipomatous mass extending from the level of the lesser trochanter to the distal third of the femur. The sciatic nerve was completely enveloped by the lipoma in the proximal segment, partially enveloped in the mid-segment and was separate from the nerve in the distal segment. The lipoma was not covered by the epineurium. The tumor was completely resected and the patient's neurologic symptoms improved. CONCLUSIONS: The pathogenetic mechanism of the reported circumferential lipoma of the sciatic nerve is not known. Two possible mechanisms considered included 1) envelopment by an extraneural lipoma over time and 2) occurrence of a lipoma in the paraneurial compartment (and in this case, extension into an extraneural one). Based on the available literature, lipomas that circumferentially envelop the entire nerve seem to be underrecognized and poorly understood. Analogous cases of lipomas enveloping nerves or other structures than nerves have been reported in the literature. Our reported case highlights the complexity of adipose lesions affecting nerves.

RESUMO

BACKGROUND: A cardiac lipoma is a rare primary cardiac tumor. They are usually asymptomatic and carry a good prognosis. Cardiac Magnetic Resonance Imaging (CMR) is the confirmatory investigation of choice. CASE PRESENTATION: We present a case of left ventricular lipoma in an asymptomatic patient, which was successfully treated with surgical resection. CONCLUSION: Cardiac lipomas are rare and are usually benign. There is no guideline on the management of cardiac lipomas and treatment is individualized.

RESUMO

Los lipomas son tumores benignos compuestos por adipocitos maduros. Si bien representan la neoplasia más común en el cuerpo humano, su aparición en la región de la cabeza y el cuello es relativamente rara. No muestra predilección por sexo y afecta a individuos en la cuarta década de vida. Clínicamente, puede observarse un aumento de volumen nodular, de consistencia blanda y superficie lisa. Su etiopatogenia aún es desconocida, aunque algunos autores han sugerido factores endócrinos, inflamatorios, hereditarios y traumáticos. El diagnóstico se realiza a través de la evaluación clínica, con la ayuda de pruebas de imagen como la tomografía computarizada y la resonancia magnética. Sin embargo, solo puede ser confirmado mediante análisis histopatológico de la lesión, considerado el examen por excelencia. El tratamiento de los lipomas y todas sus variantes consiste en la extirpación quirúrgica total, con lo cual se disminuye la posibilidad de recidivas, que es rara de por sí. El objetivo de esta publicación es informar un caso clínico de lipoma localizado en la región de la mucosa yugal, con extirpación quirúrgica completa de la lesión de manera ambulatoria (AU)


Lipomas are benign tumors composed of mature adipo- cytes. Although they represent the most common neoplasia in the human body, their occurrence in the head and neck region is relatively rare. Regardless of gender, they affect individu- als from the fourth decade of life on. Clinically, an increase of the nodular volume with softened consistency and smooth surface can be observed. Although its etiopathogenesis is still uncertain, some authors have suggested endocrinal, inflam- matory, hereditary and traumatic factors. The diagnosis is made through clinical evaluation, with the aid of imaging ex- aminations, such as computerized tomography and magnetic resonance. However, it can only be confirmed through the histopathological analysis of the lesion, which is considered the gold standard examination. The treatment of the lipomas and all their variations consists of complete surgical exci- sion, thus diminishing the possibility of recurrence, which in turn is rare. The aim of this publication is to report a clin- ical case of lipoma, located in the jugal mucosa region and treated through complete surgical removal of the lesion on an outpatient basis (AU)

RESUMO

BACKGROUND AND AIM: Lipomatous hypertrophy of the interatrial septum (LHIS), a fatty tumor, is usually diagnosed on both echo and CT/MRI imaging. Cases of LHIS located outside of the interatrial septum are extremely rare and rarer still are these cases large enough to cause symptoms. The clinical literature demonstrates a misunderstanding that fatty tumors outside the intra-atrial area represent lipomas. However, pathologic understanding of these fatty tumors is clear and is based on microscopic findings. METHODS: The tumor was removed by diving the base of attachment at the left ventricular apex via a median sternotomy on cardiopulmonary bypass. RESULTS: The patient made an uneventful recovery and remains well at 6 months postoperatively. CONCLUSIONS: On rare occasions, LHIS can arise from outside the interatrial septum. An LHIS can be differentiated from a lipoma by the presence of entrapped cardiac myocytes in LHIS, making it a pathological, rather than an anatomic, diagnosis.

RESUMO

BACKGROUND: Primary retroperitoneal neoplasms (PRN) arise from diverse retroperitoneal tissues. Soft tissue sarcomas (STS) comprise the majority and are well studied. Other non-sarcomatous PRN are very rare and less familiar. OBJECTIVES: To evaluate the clinicopathologic and radiologic features of non-sarcomatous PRN, as well as the outcome of complete tumor resection (TR). METHODS: Retrospective data were collected on consecutive patients (June 2006 to January 2015) who underwent resection of retroperitoneal lesions at our department. Final pathology of non-sarcomatous PRN was included. RESULTS: The study population included 36 patients (26% with PRN). PRN were neurogenic (17%), fat-containing (3%), and cystic (6%). The preoperative diagnosis was correct in only 28%. All patients underwent TR via laparotomy (72%) or laparoscopy (28%), for mean operative time of 120 ± 46 minutes. En bloc organ resection was performed in 11%. Complete TR was achieved in 97%. Intra-operative spillage occurred in 8%. Intra-operative, 90-day postoperative complications, and mortality rates were 11%, 36%, and 0%, respectively. The mean length of stay was 6.5 ± 5.5 days. The median overall survival was 53 ± 4.9 months. CONCLUSIONS: Familiarity with radiologic characteristics of PRN is important for appropriate management. Counter to STS, other PRN are mostly benign and have an indolent course. Radical surgery is not required, as complete TR confers good prognosis. Expectant management is reserved for small, asymptomatic, benign neoplasms.
