A Case Report of Proximal Palm Giant Lipoma Leading to Double Nerve Compression, with a Brief Literature Review

Summary: Lipomas are frequently found as benign neoplasms in humans, mainly in the head, neck, and upper limb regions. Because of their rare occurrence in hands and digits, such cases attract researchers’ attention. A case description of a 28-year-old Saudi male patient is presented with a large-size lipoma at the distal forearm, carpal tunnel, and Guyon canal area, with numbness of the central three digits and grip strength weakness of his left hand. The nature of the lesion was a benign, subcutaneous, multilobulated lipoma, removed surgically to prevent malignant transformation and deterioration in neuropathy.

Modified trident technique for surgical approach to facial lipoma.

Lipomas are the most common tumors of mesenchymal origin throughout the body. Although they have low incidence in the oral cavity, they surgical approach can be challenging. 10-year-old male with a giant lipoma in the buccal and masticator space, an intraoral surgical approach was chosen using by modifying trident technique of Ramírez-Oropeza. The main advantages and limitations of this intraoral approach are examined. An intraoral approach was selected because of less possibility of injuring the facial nerve, better esthetic results and less invasive, obtaining excellent results.

Complete encasement of the radial nerve by a giant lipoma: illustrative case.

Among the spectrum of adipose lesions associated with peripheral nerves, complete circumferential encasement of the nerve by the lesion is a very rare entity. The authors report the first case of a giant lipoma that completely and circumferentially encased the radial nerve. A 57-year-old woman presented with a large left-arm mass that she had noticed over a year following significant weight loss. She had hypersensitivity and dysesthesias in the left posterior arm but no weakness or other symptoms. Magnetic resonance imaging of the left upper limb demonstrated a large lipoma completely encasing the radial nerve, originating at the level of the spiral grove proximally and extending distally to the lateral epicondyle. The lesion was completely resected at surgery with total preservation of radial nerve function. Lipomas encasing peripheral nerves can be difficult to manage while preserving function. This case adds to the intriguing spectrum of adipose lesions associated with peripheral nerves. https://thejns.org/doi/10.3171/CASE24148.

A Case of a Giant Mesentric Lipoma in a Two-year-old Child Presenting as Koch’s Abdomen

Background and Aims: Lipomas are termed as universal tumours. They can potentially arise from any site having adipose tissue. Presence of lipomas in the intra-peritoneal region is rare, with mesentery being one of the rare locations. Methods: We present a rare case of a two-year-old child with a giant mesenteric lipoma. This child presented with malnutrition and was being treated for Koch’s abdomen. Results: The child underwent uneventful resection of mass. Conclusion: Giant mesenteric lipomas due to their size can present with various unusual symptoms. However, these seldom infiltrate and are easily operable with an uneventful intra-operative course and follow-ups.

Giant Hip Lipoma with Physical and Psychological Impact at Bamako Dermatology Hospital

Giant lipomas are voluminous benign mesenchymal tumors formed by fatty lobules from mature adipose tissue and whose exact etiological is not yet elucidated. We report the case of a 64-year-old patient with a giant lipoma at the hip with physical and psychological impact. Treatment was surgical and consisted of a wide excision of the mass. The surgical piece measured 378X303 mm and weighed 2600 grams. The surgical follow-ups were simple. The late management of lipomas can lead them to reach an inordinate size causing disabilities and increasing the possibility of neoplastic transformation. After excision, a pathological anatomopatological study is required to rule out a liposarcoma.

Giant Lipoma of the Bauhin's Valve.

Lipomas are benign tumors that can affect the digestive tract, everywhere from the hypopharynx to the rectum. Lipomas affecting the large intestine are the second most common benign tumor, after colon adenoma. We present the case of a 46-year-old patient who was initially hospitalized in the Gastroenterology Clinic with a diagnosis of gastrointestinal bleeding. The colonoscopy raised the suspicion of a malignant tumor of the transverse colon, but the computed tomography scan showed the existence of a lipoma that measured 16/11/12 cm that occupied the ascending and transverse colon, though the CT examination could not determinate the origin of the lipoma. After restoring the hydro-electrolytic and fluid balance of the patient, surgery was performed and a huge lipoma of the ileocecal valve was discovered. Extended right hemicolectomy was performed, with good subsequent postoperative recovery of the patient, who was discharged on the fifth day after the surgery. The peculiarity of this case is the huge size of the benign tumor. Lipomas with digestive system localization, although rare, must be considered in patients arriving at the Emergency Department with digestive hemorrhages, intussusception and even intestinal obstruction.

A curious case of giant omental lipoma

Primary tumors of the omentum are one of the rare causes of large intra-abdominal masses and contribute to a limited number of reported cases in the medical literature. Here, we report a case of a male child with complaints of dull abdominal pain, suspected to be a giant omental lipoma radiologically, which was confirmed on histopathology after a complete surgical resection. The case highlights the importance of various radiological modalities for the diagnosis of omental lipomas and their importance in pre-operative workup to rule out malignant pathologies, and for better anatomical characterization of the lesion for assistance in surgical planning.

A rare case of recurrent anemia with giant lipoma of jejunum: A case report

Lipoma of the gastrointestinal tract is a rare, benign, usually single, slow growing, non-epithelial neoplasms derived from mature adipocytes.3 The colon is the commonest site of the digestive tract with an incidence rate ~4.4%. Most of the lipomas are asymptomatic and incidentally detected.3 Lipoma should be differentiated from true neoplasia, because in most of the cases they do not need any intervention unless they cause a symptom or are large in size.3 Endoscopic resection is preferred for lipomas < 2cm and surgery for lipomas > 2cm to avoid complication such as bleeding and perforation. We report a case of a 40-year-old male, who was found to have 15cm jejunal lipoma by imaging and confirmed by histopathology.

A giant, recurrent, subpectoral breast lipoma: case report

Lipomas are mesenchymal tumors composed of mature fat tissue and are considered one of the most common benign tumors. They are usually small in size, and giant lipomas are rare. The exact etiology of lipoma development is unclear, though several factors have been proposed. Intramuscular or subpectoral lipomas involving the pectoralis major muscle are uncommon. In this report, the author has described the case of a 52-year-old female patient who presented with an uncommon form of subpectoral, giant, recurrent breast lipoma. The patient had undergone a complete surgical excision. The author suggests an individualized assessment and treatment of each case.

A 5 kg giant breast lipoma in a 40-year-old woman: a case report

Introduction and importance: Lipomas are benign tumours composed of adipocytes surrounded by a thin fibrous capsule. Although they make up 16% of mesenchymal tumours, the occurrence of breast lipomas is uncertain. Giant lipomas, measuring 10 cm or more in diameter or weighing at least 1000 g, commonly occur in the upper back, neck, and thigh, and are rare in the breast. Given its rarity, accurately diagnosing a giant breast lipoma is crucial to prevent potential overtreatment, as it might otherwise be mistaken for a malignant tumour. Case presentation: A 40-year-old woman presented with a painless, gradually enlarging left breast mass. Physical examination and imaging studies revealed a lipoma-compatible mass. Surgery was performed, and the 5 kg mass was enucleated and identified as a lipoma on histopathology. The patient had an uneventful postoperative recovery and was satisfied with the outcome of the surgery after 2 months of follow-up. Clinical discussion: Breast lipomas are more common in the 40–60 years age group, with giant lipomas occurring more frequently in the latter half of this age range. They can mimic various breast conditions, including neoplastic and non-neoplastic conditions, and are often treated with surgical excision to avoid recurrence. The location of the lipoma in the breast can be subcutaneous or intramuscular, and preserving the future pedicle of reduction mammoplasty/mastopexy is essential. Conclusion: Giant breast lipoma is an infrequent condition that can manifests as progressive enlargement of the breast, posing a diagnostic challenge due to its resemblance to various benign or malignant pathologies.

Giant Retropharyngeal Lipoma

Lipoma is a common soft tumor tissue that can develop anywhere in the body. The retropharyngeal space is a rare location for these benign tumors. Clinically it procures dysphagia, pharyngeal discomfort, snoring, or sleep apnea. Imaging (CT Scan and MRI) is necessary for diagnosis, extension, and previous surgical procedures. We report in this publication a giant lipoma of retropharyngeal space in 75 year old man diagnosed after dysphagia exploration and treated with trans cervical surgical approach.

PROXIMAL MEDIAN NERVE COMPRESSION DUE TO GIANT LIPOMA. SURGICAL TREATMENT UNDER WALANT.

Lipomas are benign mesenchymal tumors, which can be found anywhere in the body. In less than 1% of cases, they can be observed in distal extremities. The authors describe a rare case of a giant lipoma in the proximal third of the forearm associated with median nerve compression. WALANT surgical resection allows for a safe and complete excision of the tumor. The authors present a short review of the pertinent literature.

Insights into the Distribution Patterns of Foot and Ankle Tumours: Update on the Perspective of a University Tumour Institute.

The rarity of foot and ankle tumours, together with the numerous histological entities, presents a challenge in accumulating sufficient patients to draw reliable conclusions. Therefore, we decided to present an update of a retrospective analysis of their distribution patterns, comprising 536 cases of foot and ankle tumours presented to our tumour board between June 1997 and June 2023. Our aim was to provide a comprehensive overview of the prevalence and distribution patterns of benign and malignant bone and soft tissue tumours of the foot and ankle. A total of 277 tumours involved bone (51.7%). Of these, 242 (87.4%) were benign and 35 (12.6%) were malignant. In addition, 259 soft tissue tumours (48.3%) were found, of which 191 (73.7%) were benign and 68 (26.3%) were malignant. The most common benign bone tumours were simple bone cysts, enchondromas, osteochondromas, aneurysmal bone cysts, and lipomas of bone. Common benign soft tissue tumours included a tenosynovial giant cell tumour, haemangioma, plantar fibromatosis, schwannoma, and lipoma. The most common malignant soft tissue tumours were synovial sarcoma, malignant melanoma, and myxofibrosarcoma. In terms of anatomical location, the hindfoot was the most common site (28.7%), followed by the midfoot (25.9%), ankle (25.4%), and forefoot (20.0%). The distribution of benign entities often follows typical patterns, which may facilitate an early diagnosis even without biopsy (e.g., simple bone cyst, plantar fibromatosis). On the other hand, the distribution patterns of many rare or malignant entities are inconsistent. Individual soft tissue malignancies occur very sporadically, even over long periods of time and in specialized tumour centres. It is therefore important to recognise that any suspicious mass in the foot and ankle must be considered a possible malignancy until proven otherwise.

Giant lipoma of the vulva in a primary care setting: a case report

Les lipomes géants de la vulve sont rares. Nous présentons une femme préménopausée para-4 de 49 ans qui se présente avec une masse indolore à croissance progressive qui s'est révélée comme un lipome vulvaire après histopathologie. Une discussion détaillée est présentée et met en évidence la nécessité de l'histopathologie même dans les cas où l'imagerie pré-chirurgicale est une limitation.
 Giant Lipoma of the vulvar are rare. We present a 49-year-old para-4, premenopausal woman who presented with a painless progressively growing groin mass which was revealed as a vulvar lipoma after histopathology. A detailed discussion is presented and highlights the need to for histopathology even in cases where pre-surgical imaging is a limitation.

Giant cervical lipoma adjacent to carotid artery: a case report and literature review

Cervical lipomas accompanied by neurovascular compression are extremely rare and require surgical treatment in case of appropriate symptoms. The preferable method is gross total resection, as otherwise they tend to recur. Invasive growth is not typical for lipomas. However, large tumors can involve adjacent nerves and vessels and significantly complicate resection. We present a 57-year-old patient who underwent resection of giant soft tissue cervical lipoma invading neurovascular bundle and compressing the oropharynx and esophagus with dysphagia and positional asphyxia. The patient was followed-up for previous 5 years. Resection was necessary due to tumor enlargement with appropriate symptoms. Searching for literature data was performed in the Pubmed, Medline, EMBASE, Cochrane Library and eLibrary databases. Gross total resection of 7-cm tumor was accompanied by mobilization of hypoglossal and vagus nerves, common, external and internal carotid arteries and jugular vein with repositioning of the oropharynx and esophagus. There was mild Horner's syndrome in early postoperative period. The patient was discharged in 4 days after surgery with regression of complaints. We found only 5 reports describing giant cervical lipomas invading neurovascular bundle. Giant cervical lipomas are extremely rare, and total resection with preservation of critical structures is possible in a specialized hospital.
