Giant Intramuscular Lipoma of Biceps Brachii – A Rare Case Report

Lipomas are benign mesenchymal tumors. They are the most common type of soft tissue tumors. Intramuscular lipoma is a relatively uncommon condition and accounts for about1.8% of all primary tumors of adipose tissue and are relatively rare in upper extremity. When deep, large and unusual in location, magnetic resonance imaging (MRI) can identify and localise these tumours and is the best modality to differentiate lipoma and liposarcoma. We report an extremely rare and interesting case of giant intramuscular biceps brachii lipoma. A 22-year male patient presented with insidious onset, firm and non-tender swelling in the left elbow without any distal neurovascular deficits. MRI and biopsy were suggestive of lipoma. Wide local excision was done and patient had an uneventful recovery. Post-operative histopathology was suggestive of lipoma. To conclude, intramuscular giant lipoma of biceps brachii is an infrequent clinical entity due to its location. Imaging is necessary to differentiate it from its malignant counterpart and to plan surgical management.

Mammoth Lipoma of the Back - A Case Report

Lipomas are very common benign tumours of mesenchymal origin. Lipomas occur with an estimated prevalence rate of 2.1 per 1000 amongst all tumours that can involve in the human body. There have been only 5 cases of giant lipomas published to date.1-5 This case report describes a unique giant lipoma located in the upper back with 30 x 30 cm in measurement and weighing 3800 grams.

Giant Lipoma in Superior Vena Cava: A Case Report and Literature Review

Background: Intravascular lipomas were a rare occurrence, especially in major vessels. This tumor is composed of adipocytes in a fibrous capsule that had a slow growth rate and usually shows no symptoms. There were only eight reports in the literature regarding intravascular lipoma located in the superior vena cava.Case presentation: A 54-year-old man had episodes of supraventricular tachycardia and atrial flutter for over a year. Radiological findings preoperative showed a giant mass that arose from superior vena cava to right atrium and biopsy catheter showed that there were no signs of malignancy. The patient then underwent surgery through a median sternotomy and the mass was extirpated on the highest part of the stalk that could be reached. The patient was stable and remains to show no symptoms or evidence of residual mass or stalk in 2 years follow-up.Conclusion: The surgical approach in excising lipoma in SVC should be considered wisely with the support of adequate preoperative diagnostic. Extensive manipulation that could increase surgical technique difficulty or postoperative morbidity and mortality is not necessary since lipoma is a very slow-growing tumor.

137 Giant Lipomas of The Hand; A Case Series and Review of a Rare Tumour

Introduction Whilst lipomas are the most common tumour of the human body, it is rare in the hand. Less than 50-cases are reported in the literature. We present six-cases from a specialist hand unit, UK, presenting over a 10-year period. All patients had a distinct swelling within the affected hand which was growing in size. Method Patients were investigated with MRI and given the benign appearance; no pre-excision biopsies were performed. All excised tissue was sent for histology. Only one patient reported altered neurology of the hand, describing altered sensation within the ulnar nerve distribution of the index finger. Results In all cases, the lipoma originated in the deep palmar space from adipose tissue surrounding the deep palmar arch. They all extended distally, along natural tissue planes, encasing neurovascular and tendinous structures. In two cases the lipoma extended into the dorsum of the hand, following the perforating artery between the index and middle metacarpal heads. The lipomas all spread radialwards, penetrating the thenar muscles. The largest was 13x12x4cm in size. Conclusions Giant lipoma is a rare cause of symptomatic swelling of the hand. Compression of structures is extremely rare, but careful excision is critical as neurovascular bodies are classically enveloped within the growing lipoma.

Giant Lipoma of The Breast: Special Clinical Finding

Lipomas are the most common benign tumors of mesenchymal origin.Lipoma of breast is somewhat difficult to diagnose clinically because of fattyconsistency of breast. Giant lipoma is the mass of lipoma that exceeds atleast 10 cm in one dimension or weighs a minimum of 1000 gr.Only veryfew case reports giant lipoma of the breast available in literature becauserarity in size and location. Due to the fatty composition of the breast,difficulties in diagnosis, threatment, and reconstruction are oftenencountered.Presently, we have reported a case of this rare entity in 49years old female with giant tumor of the left breast that most of its mass,causing breast asymmetry and feel heavy. The operative finding: looks likelipoma between pectoralis major muscle and pectoralis minor muscle witha diameter of 31 cm and weighs 3.1 kg. After excision the tumor we need tomammoplasty.Pathology anatomy examination showed a lipoma.
