RESUMO

Lipomas are common benign soft tissue tumors composed primarily of mature adipose tissue. They are often encountered clinically due to their characteristic slow growth, typically as soft, painless, subcutaneous nodules. While lipomas are generally asymptomatic, surgical intervention is sought by patients when they lead to discomfort, cosmetic concerns, or functional impairment. In this case report, we present the successful surgical excision of 25 lipomas in the bilateral upper limbs and right thigh of a 43-year-old male. Pre-operative assessment, precise surgical technique, and post-operative care are highlighted as essential management components. The case emphasizes the importance of individualized treatment, ensuring symptomatic lipomas' diagnosis and effective management. This report serves as a valuable reference for healthcare professionals caring for patients with lipomatous lesions, contributing to understanding soft tissue tumor management.

RESUMO

Lipomas are common benign mesenchymal tumours, whereas lipomatoses are uncommon. Familial multiple lipomatosis (FML) is a rare syndrome characterized by multiple usually painless lipomas which may be associated with other conditions. FML is considered to be genetic, with various patterns of inheritance suggested. In this case report, we described a case of multiple familial lipomatosis that was misdiagnosed as dercum's disease.

RESUMO

AIM OF THE STUDY: Expand the differential diagnosis of secondary headache to include rare intracranial tumours, detected incidentally on brain imaging. Intracranial lipomas are rare congenital malformations, and are usually pericallosal asymptomatic midline lesions. However, some cases present with headache and seizures. Symptomatic intracranial lipomas are very rare and often detected incidentally on brain imaging. METHODS: We present a 52-year-old woman referred to our tertiary centre with a history of hypothyroidism presented with headache for 2 years. She had generalised body pains for six months. Her headache was persistent despite being on medications. Physical and neurological examination was unremarkable. Her visual acuity and fundus examination were normal. RESULTS: Her brain imaging revealed a lesion over the corpus callosum and in the interhemispheric fissure with signal attenuation on the fat suppression sequence, features suggestive of curvilinear pericallosal lipoma. Symptomatic treatment with analgesics and anti-inflammatory agents were slightly effective. It is debatable whether tumour removal is required, as the risks of surgical intervention far outweigh the potential benefits. CONCLUSION: Corpus callosal lipoma is a rare and unrecognised cause of secondary headache. It should be suspected in patients with an atypical headache without papilledema and who are unresponsive to analgesics. This may be the only presenting feature of intracranial lipomas rendering it even more difficult to suspect and diagnose, thus emphasising the importance of evaluating secondary headaches. Diagnosis is important because long-term follow-up may be required if patients develop new focal deficits, which may necessitate surgical intervention.

RESUMO

PURPOSE: Recent years have seen a paradigm shift towards total/near-total resection in spinal cord lipoma surgery. As this procedure is technically challenging, surgical candidates need to be selected appropriately through accurate image assessment and classification. The purpose of this paper is to describe a surgical series of paediatric spinal cord lipomas, their diagnosis, results and complications. METHODS: We undertook a retrospective review of paediatric patients with spinal cord lipomas who underwent surgery between 2008 and 2022. The variables studied were age, gender, preoperative symptoms according to the Necker Functional Score (NFS), type of lipoma according to Morota's classification, functional and radiological surgical outcomes using the cord-sac ratio (CSR), need for re-operation, complications and follow-up. RESULTS: A total of 25 patients (average age 36 months) underwent surgery. According to Morota's classification, MRI showed 13 type 1 lipomas, two type 2, two type 3 and eight type 4. The preoperative NFS was 16.06, with urological abnormalities being the most frequent manifestation. Total/near-total resection was attempted since 2015. Five patients with type 1 lipoma required re-operation due to clinical deterioration with suspected retethering, all of them with a CSR > 0.3. The series average CSR was 0.417. CONCLUSIONS: This paper highlights the importance of proper classification for a correct surgical approach to obtain favourable results and minimise possible complications. Based on our experience, given our results regarding the percentage of fistulae and retethering rates, we limited radical resection to symptomatic type 1 lipomas. Our future aim is to obtain better CSR rates and to decrease the retethering percentage.

RESUMO

Introduction and importance: Gastric lipoma (GI) is a rare benign tumor of the stomach that arises from adipose tissue. It is often asymptomatic and is incidentally diagnosed on endoscopy or imaging studies. Case presentation: A 66-year-old male presented with epigastric pain and acid reflux. Upper gastrointestinal endoscopy revealed a 3-cm submucosal lesion in the pyloric antrum. The patient underwent a subtotal gastrectomy. The specimen was sent to the pathology department. Based on the microscopic findings, the diagnosis was a submucosal GI. Discussion: The diagnosis of GIs is usually made incidentally during imaging studies. Treatment options include endoscopic or surgical resection; however, conservative management can be considered in asymptomatic patients. Periodic radiological surveillance is recommended to monitor growth and assess for any malignant transformation. Conclusion: GI is a rare tumor that is usually asymptomatic but can present with nonspecific gastrointestinal symptoms. The diagnosis is confirmed through histological examination, and imaging techniques such as computed tomography or MRI can be useful in preoperative evaluation. Surgical resection remains the primary treatment, while endoscopic resection may be considered in certain cases.

RESUMO

Most intracranial lipomas are asymptomatic, but headache is the most common symptom. The pounding score is sometimes high. Therefore, it is necessary to monitor imaging findings in parallel with the treatment of migraine.

RESUMO

This review summarises the classification, anatomy and embryogenesis of complex spinal cord lipomas and describes in some detail the technique of total lipoma resection and radical reconstruction of the affected neural placode. Its specific mission is to tackle two main issues surrounding the management of complex dysraphic lipomas: whether total resection confers better long-term benefits than partial resection and whether total resection does better than conservative treatment, i.e. no surgery, for asymptomatic lipomas. Accordingly, the 24-year progression-free survival data of the senior author and colleagues' series of over 300 cases of total resection are compared with historical data from multiple series (including our own) of partial resection, and total resection data specifically for asymptomatic lesions are compared with the two known series of non-surgical treatment of equivalent patients. These comparisons so far amply support the author's recommendation of total resection for most complex lipomas, with or without symptoms. The notable exception is the asymptomatic chaotic lipoma, whose peculiar anatomical relationship with the neural tissue defies even our aggressive surgical approach, and consequently projects worse results (admittedly of small number of cases) than for the other two lipoma subtypes of dorsal and transitional lesions. Prophylactic resection of asymptomatic chaotic lipomas is therefore not currently endorsed. We have also recently found that some dorsal lipomas with clear outline of the conus on preoperative imaging had a significantly better long-term prognosis of preserving neurourological functions without surgery. Whether this subset of lipomas should be managed conservatively until symptoms arise is now an open question awaiting a longer follow-up of a larger cohort of such patients.

RESUMO

INTRODUCTION AND IMPORTANCE: Lipomas of the gastrointestinal tract are a rare entity compared to the more common tumors of the gut, such as adenomatous polyps and carcinomas. They were first described by Bauer in 1757. Gastrointestinal lipomas can grow in all segments of the gut, with the highest frequency in the colon. In this case report, we present a rare case of gastrointestinal lipoma mimicking colonic malignancy and causing intussusception, necessitating emergent surgery. This paper highlights the potential diagnostic challenges and therapeutic interventions associated with GI lipomas. CASE PRESENTATION: A 28-year-old female presented with symptoms of abdominal pain, weight loss, vomiting, and changes in bowel habits. Initially, she received a misdiagnosis of Irritable Bowel Syndrome. Subsequent investigations indicated the possibility of colonic malignancy. During the intra-operative biopsy, it was ultimately discovered that she had a colonic lipoma. CLINICAL DISCUSSION: CT revealed an abdominal mass and an intussusception, indicating the need for surgical intervention. A laparoscopic procedure was performed to remove the mass, which alleviated the symptoms. Subsequently, a histological examination confirmed the mass to be a lipoma. CONCLUSION: Differentiating a gastrointestinal lipoma from malignancy is crucial, and careful investigation is necessary to determine if a local excision can be performed instead of a wide excision.

RESUMO

BACKGROUND: Spinal lipomas not associated with dysraphism are rare and have an unknown natural history. In this report, we describe two cases; they showed recurrence during long-term follow-up, which makes us doubt a benign malformative etiology. CASE REPORTS: Two patients, a 19-year-old South American woman and a 14-year-old boy with spinal lipomas, underwent surgical resection. The lipomas were not associated with dysraphism and were located in the cervicothoracic and craniocervical junctions. In both cases, we decided to operate due to clinical progression; the former had a progressive natural course, and the latter experienced clinical worsening after recurrence from previous surgeries. The surgery took place with the assistance of neurophysiological monitoring and intraoperative ultrasound; a partial resection and medullary decompression were done, following the more recent recommendations. DISCUSSION: The natural history of these lesions is currently unknown due to their rarity and the heterogeneity in the long-term follow-up of previously reported cases. Although previous reports describe good outcomes after surgical resection, long follow-ups, especially in young subjects, may show differences in these outcomes with progression and recurrence. We contribute to this last piece of evidence by describing two more cases of progression and recurrence. LESSONS: Long-term close follow-up should be done in young subjects with spinal lipomas, as they are more prone to an aggressive course. Metabolism and hormonal changes may be behind this progression. Reoperation must be considered if neurological decline is detected.

RESUMO

BACKGROUND: Intracranial lipomas are rare congenital malformations at characteristic sites. Though largely asymptomatic, some cause significant morbidity. We are studying this for the local population.  Objectives: The purpose of this article is to analyze the spectrum of intracranial lipomas, determine their distribution at characteristic locations, and assess their associations.  Method: A retrospective study of 21 patients diagnosed with intracranial lipomas detected on CT and MRI performed between September 2017 and May 2022 at Dr. D.Y. Patil Medical College, Hospital & Research Center, Pune. RESULTS: Amongst the 21 patients with intracranial lipomas, the most common location was the pericallosal region seen in 11 patients (n = 11, 52.3%), of which nine were curvilinear type (n = 9), more common than tubular nodular type (n = 2). Other locations (n = 10, 47.7%) were found to be; quadrigeminal cistern in six patients (28.5%), cranial diploic space in two patients (9.5%), one each in interhemispheric falx (4.8%), and cribriform plate (4.8%). Associated anomalies were observed in three patients, which were fronto-ethmoidal encephalocele (n = 1), partial agenesis of the corpus callosum (n = 2), extension with a frontal subcutaneous lipoma (n = 1), and bilateral intraventricular extension (n = 1). Presenting symptoms were headache and dizziness (38.1%), seizures (19%), swelling on the forehead (9.5%), and other non-specific clinical symptoms (33.3%). CONCLUSION: Intracranial lipomas are rare congenital lesions that are usually asymptomatic and discovered incidentally. However, lipomas at interhemispheric locations can cause seizure disorders and some present with headaches and dizziness. Few have associations like communication with extracranial swellings and corpus callosum agenesis.

RESUMO

Chaotic lipomas are an extremely rare variant of spinal lipomas. This entity was first defined in 2009 by Pang and colleagues. Not much has been written about this variant. Its characteristic is the haphazard distribution of DREZ (Dorsal root entry zone), nerve roots and placode-lipoma interface. Thus complete/near-total excision of this lesion is quite difficult. We describe a case of chaotic spinal lipoma and elucidate the challenges faced in the management of this entity and review the literature. We performed a thorough systematic review with the keyword 'chaotic', 'Lipomyelomeningocele', 'Complex Lipomyelomeningocele', 'LMMC', 'Lumbar lipoma', 'spinal lipoma' in the google scholar and PUBMED data system for indexed literature on the above topic with no particular time frame. The studies quoted range earliest from 1970 till currently. Additional potential relevant articles were further retrieved through a manual search of references from original reports. Out of 42 studies, a total of 21 publications were selected which could have encountered a chaotic variant, but due to the term introduced only recently in 2009, may have been described differently. Studies encompassing true lipomeningomyelocele were excluded from our review. What we found out? Chaotic lipoma may not be a new entity. The scarce description in literature may be in part due to non-introduction and unclear description of this term earlier. The management of this variant is particularly challenging with basic principles remaining the same. Meticulous near-total excision and placode-lipoma construct are the major obstacles.

RESUMO

BACKGROUND: Lipomas are the most frequent benign tumor. They have been described as soft, well-defined, slow-growing palpable masses, and classified as deep or superficial. PURPOSE: To present the clinical and ultrasound findings of herniated superficial subcutaneous lipoma (HSL), located in pressure/support areas, not previously described. MATERIAL AND METHODS: A seven-year retrospective review was performed. Patients with a preoperative high-resolution ultrasound (HRUS) diagnosis of HSL archived in the computational system and histological study information were selected. RESULTS: A total of 37 patients (mean age = 46 years) were recruited. The clinical diagnoses were "lipoma" or "suspected lipoma" in just 46% of the cases. This was three times more frequent in women. Tumors were located mainly in the gluteal (38%) and proximal thigh areas (35%). Clinically, all patients showed small, soft, rounded skin nodules. On HRUS, they appear as lipomatous tumors that protruded, compressed, and thinned the covering dermal layer. The subcutaneous portion was bigger than the herniated part, with an iceberg image. CONCLUSION: HSL in support areas have a special clinical ultrasound presentation, not previously described. It is important to recognize them for a proper diagnosis and treatment, especially because they clinically may present as small superficial lesions; however, they are associated with a larger subcutaneous portion (iceberg image). It is probable that an estrogen influence on the adipose tissue can be suspected because of the female predominance.

RESUMO

Los lipomas colónicos son tumores benignos poco frecuentes, extremadamente raros a nivel rectal. A pesar de ello, ocupan el segundo lugar en frecuencia detrás de los pólipos adenomatosos. Aunque la mayoría de los lipomas colorrectales son asintomáticos y se descubren incidentalmente, en ocasiones pueden ser sintomáticos y determinar complicaciones agudas que requieren tratamiento quirúrgico de urgencia. Estas formas de presentación pueden confundirse con las del cáncer colorrectal, constituyendo un desafío diagnóstico y terapéutico. Presentamos el caso de una paciente que consultó en emergencia por una gran masa dolorosa de aparición aguda a nivel del ano, resultando ser un lipoma rectal prolapsado a través del canal anal.


Colonic lipomas are infrequent benign tumors, extremely rare at the rectum. Nevertheless, they follow in frequency polyp adenomas. Even though most colorectal lipomas are asymptomatic and incidental, they can occasionally be symptomatic and develop acute complications that require urgent surgical treatment. This form of presentation can be confounded with colorectal cancer, therefore impairing diagnosis and treatment. We present the case of a female patient who came to the emergency room with an acute painful mass through the anus, that resulted in a prolapsed rectal lipoma.

RESUMO

Lipomas are benign soft tissue tumors; the most common ones present in subcutaneous planes distributed throughout the body. However, there are few sites which are unusual location for lipomas. Here, we discuss the presentation of 4 cases of head and neck lipomas at unusual subsites. Though its prevalence is high in the body, lipomas are rarely seen in upper aerodigestive tract and these lesions can cause severe deglutition and respiratory distress problems in addition to cosmetic deformities. In the head and neck, most common location of lipoma is the cheek, followed by the tongue. Tonsillar lipomas are very rare. The mainstay treatment for lipomas is complete surgical excision and recurrence following complete removal is rarely known. We are here discussing a series of 4 cases of lipomas, presenting at uncommon subsites in head and neck region. These include lesions over neck, tongue, palate and tonsillar fossa. Lipomas are benign mesenchymal tumors, that are initially non bothersome. However, with increasing size they can cause severe aerodigestive problems with functional compromise and need complete surgical excision.

RESUMO

Cardiac lipomas are rare primary cardiac tumors that are often only detected incidentally during other examinations. Lipomas of the right atrium are particularly rare. In this report, we describe the case of a patient presenting with a mixed cystic-solid lipoma in the right atrium. The symptoms, imaging findings, and treatment strategies associated with this case are discussed herein. This 65-year-old female patient reported to our hospital due to exertional chest tightness, shortness of breath, and occasional chest pain for over 1 year. She subsequently underwent transthoracic echocardiography and contrast-enhanced ultrasonography, both of which revealed a cystic-solid mass in the right atrium. The transthoracic computed tomography scan showed a dense patchy shadow in the right atrium. The mass was completely excised from the atrial septum, and subsequent histopathological examination confirmed its identity as a lipoma. Surgical resection remains the primary treatment approach for cardiac lipomas, and multimodal imaging is of key importance for the diagnosis and follow-up monitoring of affected patients.

RESUMO

INTRODUCTION AND AIMS:  Duodenal polyps are rare in patients undergoing upper gastrointestinal endoscopy. The present study is an experience of the histopathological spectrum of the duodenal polyps and its correlation with the clinical and endoscopic findings in a tertiary care centre. MATERIALS AND METHODS: The present study is a 10-year retrospective study from the year 2011 to 2020. All the relevant clinical, endoscopic and radiologic findings were retrieved from the hospital medical records. Old histopathology slides were restained, and wherever required, special stains and immunohistochemistry (IHC) were performed. All the cases were reviewed. The present study mainly included descriptive statistics with categorical and continuous variables. RESULTS: Total 81 cases of duodenal polyps were studied in the period of 10 years. The median age was 48 years. Male: female ratio was 2.2:1. The most common presenting system was abdominal pain. We experienced both solitary and multiple polyps. The majority of the duodenal polyps were non-neoplastic, with unremarkable mucosa or inflammatory type. Unlike previous studies the most common site for the hyperplastic polyp in the present study was the first part of the duodenum. Among the neoplastic polyps, adenomatous polyp was the most common type. Contrary to the previous studies, our study showed the first part of the duodenum as the most common site for the sporadic nonampullary adenomatous duodenal polyps. Of the rare entities, we encountered a single case each of lipomatous polyp and gangliocytic paraganglioma. Among the syndromes we encountered two cases of Peutz-Jeghers syndrome and one case of familial adenomatous polyp in our study population.CONCLUSION Duodenal polyps are a rare finding on endoscopic examinations, though most of them are non-neoplastic in nature, vigilant examination under the microcope is required to rule out any neoplastic pathology and identify the risk of malignancy.

RESUMO

A benign soft tissue tumor of mature fat cells is called a lipoma (adipocytes). Lipoma can develop anywhere on the body, although it is uncommon in the mouth. Lipomas that are superficially positioned are often yellowish in color, painless, soft, and non-fluctuating with a thin epithelial surface. As a result, a delicate pattern of blood vessels is frequently seen on the surface. Deeper lesions might not exhibit this finding and, as a result, are not as clinically recognized. Since the patients do not report any subjective clinical symptoms, the dentist often diagnoses such lipomas by accident. Deep-seated lipomas require specialist imaging procedures, such as contrast-enhanced computed tomography, magnetic resonance imaging, or ultrasound to determine their extent. Lipomas can range in size from tiny to large to enormous. Large lipomas typically feature a "slip sign" and a nodular surface. Giant-sized lipomas can have a diameter of up to 10 cm. Lipomas can be single or multicellular. Dercum's disease, Proteus syndrome, neurofibromatosis, and familial adenomatosis polyposis all exhibit lipomas in various locations. The preferred course of treatment for these oral lipomas is surgical removal. Such lipomas do not recur again. Lipoma comes in a number of tiny varieties. The traditional description is of a well-defined tumor made up of lobules of uniformly sized and shaped mature fat cells. The term "fibrolipoma" refers to lipomas that contain a sizable amount of fibrous connective tissue, "angiolipoma" refers to lipomas that contain numerous tiny blood vessels, "myxolipoma" refers to lipomas with a background of myxoid cells, and "spindle cell lipoma" refers to lipomas that contain a mixture of uniform spindle cells. When compared to a pleomorphic liposarcoma, the pleomorphic lipoma exhibits spindle cells and strange, hyperchromatic large cells, making it challenging for the pathologist to tell them apart. An intramuscular lipoma is a lipoma that invades skeletal muscle bundles. Because they are harder to entirely eradicate, intramuscular lipomas are more likely to reoccur.

RESUMO

Non-endocrine findings in patients with MEN1 (multiple endocrine neoplasia) syndrome also include skin lesions, especially tumor-type lesions. This is a narrative review of the English-language medical literature including original studies concerning MEN1 and dermatological issues (apart from dermatologic features of each endocrine tumor/neuroendocrine neoplasia), identified through a PubMed-based search (based on clinical relevance, with no timeline restriction or concern regarding the level of statistical significance). We identified 27 original studies involving clinical presentation of patients with MEN1 and cutaneous tumors; eight other original studies that also included the genetic background; and four additional original studies were included. The largest cohorts were from studies in Italy (N = 145 individuals), Spain (N = 90), the United States (N = 48 and N = 32), and Japan (N = 28). The age of patients varied from 18 to 76 years, with the majority of individuals in their forties. The most common cutaneous tumors are angiofibromas (AF), collagenomas (CG), and lipomas (L). Other lesions are atypical nevi, basocellular carcinoma, squamous cell carcinoma, acrochordons, papillomatosis confluens et reticularis, gingival papules, and cutaneous T-cell lymphoma of the eyelid. Non-tumor aspects are confetti-like hypopigmentation, café-au-lait macules, and gingival papules. MEN1 gene, respective menin involvement has also been found in melanomas, but the association with MEN1 remains debatable. Typically, cutaneous tumors (AF, CG, and L) are benign and are surgically treated only for cosmetic reasons. Some of them are reported as first presentation. Even though skin lesions are not pathognomonic, recognizing them plays an important role in early identification of MEN1 patients. Whether a subgroup of MEN1 subjects is prone to developing these types of cutaneous lesions and how they influence MEN1 evolution is still an open issue.
