RESUMO

Among all intramedullary spinal cord lesions, intramedullary spinal cord lipomas account less than 1%. Non-dysraphic intramedullary lipoma is very rare. It is most commonly seen in cervicodorsal region followed by cervico bulbar, lumbar and sometimes multiple. Here we present a 17-year-old female who underwent MRI due to upper dorsal pain followed by progressive bilateral lower limb weakness which showed intramedullary lesion extending from T1-T9, involving eight vertebral segments with distal syrinx and features suggestive of lipoma. Patient underwent surgical decompression of lipoma. Patient had an uneventful post-operative period. Diagnosis confirmed by histopathology.

RESUMO

Lipoma is a benign soft tissue tumour. It is a benign proliferation of mature adipocytes. It is described as giant when its weight exceeds 1 kg or its diameter exceeds 5 cm. Functional and aesthetic impairment may be a major reason for surgical excision. It can be located everywhere, but it mainly occurs in the posterior segment of the chest. We here report a case of giant lipoma of the left posterior-superior segment of the chest.

RESUMO

Filum lipomas, a subtype of spinal lipomas, are ectopic fat tissue deposits of the filum terminale categorized as closed spinal dysraphism. They are occasionally and incidentally observed on MRI images, but generally require little surgical treatment. Early untethering surgery is recommended for symptomatic patients, whereas asymptomatic patients presenting normal level of the conus medullaris require no therapy and are regarded as having a normal variation. Prophylactic untethering surgery can be an option for asymptomatic patients with low set conus medullaris. Untethering surgery should be safely conducted using electrophysiological procedures. Herein, we summarize the clinical characteristics of the filum lipoma and describe our routine surgical procedures.

RESUMO

Lipoma of the conus medullaris(LCM)can cause neurological symptoms known as tethered cord syndrome(TCS). The symptoms can be seen at diagnosis and during long-term follow-up. Even after surgical treatment, some patients can present with neurological deterioration indicating a TCS, defined as retethered cord syndrome(ReTCS). In this report the surgical technique for conus lipoma comprising wide osteoplastic laminotomy with confirmed whole spinal lipoma and adjacent normal spinal tissue is described, with dissection performed from the proximal side to the distal side with confirmed normal spinal cord and roots under operative microscope, expansive dural plasty aiming to get low cord/sac ratio was reported. Considering that some patients with LCM show postoperative neurological symptoms due to TCS in a long-term follow-up period, careful postoperative follow-up is necessary.

RESUMO

Nodular fasciitis (NF) is a peculiar, rapid-growing soft tissue lesion, typically appearing in subcutaneous tissue. Approximately 20% of NF occurs in the head and neck region, where they can involve any anatomic site. Laryngeal involvement, however, is quite rare. Lipoma is recognised as a slow growing, benign mesenchymal tumour; myxolipoma is a rare variant which has a prominent myxoid background. Laryngeal lipoma is infrequent, accounting for only 0.6% of all benign laryngeal lesions. We report a 61-year-old male patient with laryngeal nodular fasciitis coexisting with myxolipoma who presented to a tertiary care hospital in Ar Ramtha, Jordan, in 2020. Radiological and histological findings were indicative of laryngeal nodular fasciitis and myxolipoma was incidentally diagnosed. Following trans-oral debulking of the lesion the mass enlarged rapidly and the patient underwent a tracheostomy with complete mass excision and right partial laryngectomy through an open surgical approach. The patient had an uneventful recovery with no evidence of recurrence. The purpose of this report is to broaden the differential diagnosis of rapid-growing laryngeal masses that cause airway obstruction and to stress the significance of integrative interdisciplinary collaboration to establish an accurate diagnosis, thereby allowing proper management for benign pathologies and avoid futile aggressive treatment.

RESUMO

We report the case of a rare lipoma arising in the epidural space of a 14-year-old boy without spinal dysraphism. Lipomas are rare in pediatric soft tissue tumors, accounting for only about 4% of cases. The incidence of an intraspinal epidural lipoma without spinal dysraphism is extremely rare in pediatric patients. In this case, the patient had progressive motor deficits in the lower extremities and difficulty in urination and defecation. Magnetic resonance imaging showed an extradural tumor compressing the spinal cord at the T3-T7 level. Because of the progressive neurological deficits, we performed an emergency surgery. The tumor was completely resected en bloc, and histopathology revealed mature adipose tissue with fibrous septa, diagnosed as atypical lipomatous tumor / well-differentiated liposarcoma. The patient fully recovered and there was no tumor recurrence for 6 years since the surgery. However, re-examination using fluorescence in situ hybridization after 6 years of surgery changed the diagnosis to lipoma as no amplification of murine double-minute type 2 oncogene was observed. In liposarcoma, histopathological diagnosis using fluorescence in situ hybridization is mandatory. Our case illustrates that immunohistochemical diagnosis alone can be misleading. Hence, prompt surgery is required for progressive neuropathy.

RESUMO

ABSTRACT: Folliculosebaceous cystic hamartomas (FSCH) are a rare form of cutaneous hamartoma composed of follicular, sebaceous, and mesenchymal elements. These lesions are most often seen in the central face and scalp and rarely exceed 2 cm in size. Here, we report a case of a folliculosebaceous cystic hamartoma with a prominent adipose tissue component resembling a spindle cell lipoma. The patient is a 36-year-old man with a slowly enlarging, flesh-colored, lobulated lesion on his right ala that had been previously biopsied. The clinical differential included a hypertrophic scar or recurrent hamartoma. A full-thickness excisional biopsy was performed, which revealed prominent, large, irregularly shaped, folliculosebaceous structures, including multiple dilated follicles associated with prominent hyperplastic-appearing sebaceous glands, findings consistent with FSCH. The mesenchymal component contained a proliferation of spindle-shaped cells associated with mucin and thickened, ropey-appearing bundles of collagen, features mimicking a spindle cell lipoma. This combination of a folliculosebaceous cystic hamartoma with prominent adipose tissue resembling spindle cell lipoma is unusual and has only been previously reported once in the literature, and therefore, our case contributes to the expanding knowledge of this rare variant of FSCH.

RESUMO

Intussusception is a rare condition in adulthood and there exists an underlying pathological lesion in most cases. Colorectal lipoma is the second most common benign tumour of the colon. Although commonly asymptomatic, it can present with intussusception. We, herein, report a case of a 79-year female with a yellowish mass with irregular surface prolapsing through the anal canal. In computed tomography (CT), sigmoido-rectal intussusception plus a lesion with the regular borders originating from the distal sigmoid colon protruding through the anal canal were observed. We resected the lesion with a transanal approach, following which the intussusception resolved spontaneously. Histopathological examination had reported lipoma. Transanal resection is a safe and efficient method of the treatment in distal colorectal lipomas presenting with intussusception. Key Words: Colorectal lipoma, Sigmoido-rectal intussusception, Transanal resection.

RESUMO

RATIONALE: Lipoleiomyoma is a rare neoplasm of the uterus. It is considered a variant of uterine myomas. Its reported incidence varies from 0.03% to 0.2%. Lipoleiomyoma consists of variable proportions of mature lipocytes and smooth muscle cells. These tumors generally occur in asymptomatic obese perimenopausal or postmenopausal women. About 90.7% of lipoleiomyomas arise from the uterine corpus, with only 6.5% arising from the cervix. When it occurs in the cervix, it is difficult to diagnose and treat it. We report an uncommon case of pelviscopic resection of uterine cervical lipoleiomyoma showing continuous growth after menopause. PATIENT CONCERNS: A 55-year-old postmenopausal woman was diagnosed with 40 mm-sized uterine myoma 4 years ago. The size of the mass increased to 58 mm in the last year. DIAGNOSES: An ultrasound scan revealed a 58 × 34-mm-sized round hyperechogenic and barely vascularity mass that appeared to have originated on the left side of the uterine cervix. Final pathologic findings showed lipoleiomyoma. INTERVENTIONS: After admission to the hospital, we performed pelviscopic removal of uterine lipoleiomyoma and both tubes. Microscopic examination revealed a significant amount of fat cells between muscle cells. OUTCOMES: Surgeries were successful. The patient had been followed up regularly for three years after surgery. She did not experience any complications. She remained disease-free. LESSONS: Although lipoleiomyomas mainly occur in postmenopausal women, they can also occur in the uterine cervix. They can increase in size after menopause. They can be removed laparoscopically. If a hyperechoic mass occurred in the uterus after menopause that keeps growing without symptoms, a differential diagnosis of lipoleiomyomas must be performed.

RESUMO

Primary adrenal teratoma is a rare lesion with a high misdiagnosis rate. In view of the fact that adrenal teratoma and adrenal gland are often inseparable, the removal of the affected adrenal gland seems inevitable. Thus, it is necessary for clinicians to differentiate adrenal teratoma from common adrenal lipoma diseases, such as adrenal angiomyolipoma, adrenal myelolipoma, lipoma, gangliocytoma, and so on. In this study, we reported the clinical and pathologic features of 7 patients surgically treated for adrenal mature teratomas from 2007 to 2020 in our hospital. We compared the clinical characteristics and surgical management in literature review cases with our cases. All patients were females and underwent open adrenalectomy or laparoscopic adrenalectomy, respectively. In our cases, there was no recurrence during the longest follow-up of 13 years. Adrenal teratoma is rare and easy to ignore. And once misdiagnosed, the surgeon may need to adjust the operation temporarily, extend the operation time and finally increase the operative risks. Our aim is mainly to help clinicians to raise awareness of adrenal teratomas, improve the diagnosis rates and optimize the treatment decision-making of this disease.

RESUMO

RATIONALE: Lipomas are tumors composed of mature adipocytes, originating from the mesoderm, and are the most common soft tissue tumor. According to the World Health Organization classification of human soft tissue and bone tumors, there are 14 types of benign tumors, including mature adipose tissue. Osteolipoma is known as the rarest subtype of lipoma. PATIENT CONCERNS: A 63-year-old female presented to our hospital for the evaluation and treatment of a palpable mass with pain in the right knee. DIAGNOSIS: The diagnosis was confirmed as lipoma with osteocartilaginous metaplasia. INTERVENTIONS: Surgical removal of the tumor was performed. OUTCOMES: The main symptoms improved immediately after the surgery and recovered without any complications or recurrence until 2 years after surgery. LESSONS: Lipoma with osteochondral degeneration is a rare variant of lipoma and it is important to differentiate it from other malignant tumors. Pathological confirmation should be performed after marginal resection of the mass.

RESUMO

Hibernomas are soft tissue tumors derived from remnants of brown fat. They are rare masses that can have variable presentations ranging from incidental asymptomatic masses to pain due to nerve compression. We present the case of a 52-year-old male presenting with an atypical lipomatous mass on ultrasound and magnetic resonance imaging. The mass was excised and sent for pathology with the result being a hibernoma. We should be vigilant in the treatment of such tumor presentations as they may be a low grade liposarcoma in disguise. Surgical biopsy or excision is the best treatment for achieving a definite diagnosis.

RESUMO

Duodenal lipomas are uncommon and rare causes of gastrointestinal bleeding. Here, we present the case of a 45-yearold male patient who was admitted to University Clinical Centre because of melaena. After initial diagnostics, including echosonography, esophagogastroduodenoscopy revealed bleeding from protruding blood vessel at the polypoid submucosal change in the posterior duodenal bulb. Upon two urgent unsuccessful endoscopic hemostasis, a duodenotomy was performed. Definitive diagnosis was based on histological findings, describing duodenal lipoma with Bruner's gland hyperplasia. Upper GI bleeding is a serious challenge that requires adequate diagnostics necessary for the right choice of therapeutic approach. Unsuccessful endoscopic hemostasis could be followed by serious complications in bleeding duodenal lipoma when surgery should be always considered as the treatment of choice in patients with this kind of bleeding tumor. KEY WORDS: Bruner Glands Hyperplasia, Duodenal Lipoma, Upper Gastrointestinal Bleeding.

RESUMO

CASE: We present a case of a patient who suffered from wrist swelling and had symptoms of carpal tunnel syndrome. The patient underwent ultrasound and magnetic resonance imaging, in which signs of joint effusion and a fatty synovial lesion were presented. The treatment included open excision of the tumor. In addition, the palmaris longus muscle had an anatomic variation with proximal and distal tendon portions. The histopathological examination disclosed lipoma arborescens of the synovial membranes of the joints. CONCLUSION: The recognition of this entity and its characteristics are important not only for correct diagnosis but also for the appropriate treatment.

RESUMO

RATIONALE: Intraspinal choristoma is a relatively uncommon intervertebral canal tumor. Prior to our reports, only 2 cases of intraspinal choristoma had been reported. Because this disease is not common and looks like a mass of fatty tissue on the magnetic resonance imaging (MRI), intraspinal choristoma can be easily misdiagnosed as teratomas or lipomas (like the case of this article presenting) without a pathology report. So if a lumber intraspinal lesion is discovered in a clinical examination, intraspinal choristoma should be considered as a differential diagnosis. We present a case of intraspinal choristoma that is unlike any other reported case. PATIENT CONCERNS: A 35-year-old woman with left lower extremity hypoesthesia and burning-like pain in the lumbar region for 1 month visited the local hospital for plain lumbar spine MRI. The patient was diagnosed with a lumbar space-occupying lesion. A second plain lumbar spine MRI scan and a MRI scan with enhancement were performed in our hospital to confirm the presence of a congenital lipoma in the spinal canal. A postoperative biopsy of the lumbar spinal mass indicated that the mass was an intraspinal choristoma located in the spinal canal. DIAGNOSIS: Intraspinal choristoma. INTERVENTION: The lesion was surgically removed, and follow-up plain and enhanced MRI images of the patient's lumbar spine were obtained. OUTCOMES: After surgery, the patient no longer experienced the burning pain in her lumbar region or the left lower extremity hypoesthesia when the patient was discharged. And there was no evidence of recurrence 2 years after the surgery. LESSONS: The MRI presentation of intraspinal choristoma is similar to intraspinal lipoma. Therefore, a pathological assessment is critical to provide an accurate diagnosis.

RESUMO

Pulmonary hamartomas are common benign lung tumors. Most cases are parenchymal chondromatous hamartomas, whereas endobronchial lipomatous hamartomas are rarely encountered. A 78-year-old man was referred for left superior subsegmental atelectasis due to obstruction by an endobronchial tumor that was found incidentally on chest computed tomography for the postoperative follow-up of colon cancer. Bronchoscopy showed a polypoid tumor in the orifice of the left upper segmental bronchus. Lipoma was diagnosed by a bronchoscopic biopsy. We performed a segmentectomy of the upper division of the left lung because the tumor was presumed to be located peripherally to the left B3 segmental bronchus. A histopathological examination revealed that the tumor was an endobronchial lipomatous hamartoma that extended to the pulmonary parenchyma beyond the bronchial wall.

RESUMO

A quadragenarian male presented with gradual protrusion of the left eyeball for 7-8 months' duration. On examination, the best corrected visual acuity in the right eye was 20/20, while in the left eye there was no light perception. Contrast-enhanced CT scan revealed a well-defined fat-density mass in the extraconal compartment of the left superior orbit, causing inferolateral globe dystopia with resultant stretching of the optic nerve. Provisionally, orbital dermoid or lipoma was considered in the differential diagnosis. Anterior orbitotomy with complete excision of the mass was performed under general anaesthesia. Histopathological examination revealed an encapsulated, lobulated lesion consisting of mature lipocytes and occasional blood vessels with thrombi. The lesion was divided into numerous lobules by thick fibrous bands. Immunohistochemical stain S100 was strongly positive in the lipocytes. At 3 months of follow-up, the patient had moderate ptosis with leucomatous corneal opacity with no recurrence.
