angiolipoma

Angiolipomas are rare, benign tumors characterized by a mixture of adipose tissue and blood vessels, distinguishing them from lipomas. This case involves a 52-year-old woman with no significant medical history who presented with generalized weakness, fatigue, and intermittent, painless rectal bleeding over six months, initially dismissed as hemorrhoidal. Despite exhibiting mild pallor and trace rectal bleeding upon examination, significant iron-deficiency anemia was diagnosed through laboratory tests. Incorporating colonoscopy and computed tomography, the diagnostic process identified a 2 cm submucosal lesion in the ascending colon, characterized as a well-defined, fat-density mass...

Introduction Benign lipomatous tumors are soft tissue tumors that exhibit a predominant adipocytic phenotype. Lipomas are the archetype and are the most common benign soft tissue tumors in adults but relatively uncommon in children. Their sex incidence is equivocal. They sometimes occur in combination with other mesenchymal elements, giving rise to variants including fibrolipoma, angiolipoma, myolipoma, spindle cell lipoma, chondroid lipoma, osteolipoma, and chondrolipoma. Their clinical significance is mainly due to the cosmetic disfigurement of patients and the differential diagnosis of malignant soft tissue tumors...

Angiolipoma is a benign mesenchymal tumor and its occurrence in head and neck region is very rare. Only 2 cases of Laryngeal angiolipomas have been reported in the medical literature. We present one such rare case in a 32-year-old male who presented with complaints of change in voice and foreign body sensation in the throat since past 9 months along with features suggestive of obstructive sleep apnoea and dysphagia. Contrast enhanced CT scan of the neck showed a cystic lesion arising from right ventricle extending superiorly till the vallecula, partially obstructing the airway...

Intussusceptive angiogenesis (IA) and intussusceptive lymphangiogenesis (IL) play a key role in the growth and morphogenesis of vessels. However, there are very few studies in this regard in vessel tumors (VTs). Our objective is to assess the presence, characteristics, and possible mechanisms of the formation of intussusceptive structures in a broad spectrum of VTs. For this purpose, examples of benign and malignant blood and lymphatic VTs were studied via conventional procedures, semithin sections, and immunochemistry and immunofluorescence microscopy...

Angiolipomas are uncommon benign masses of the breast which are rarely described in the male breast. They do not have a typical mammographic appearance and can present with concerning features such as microcalcifications or irregular borders. Ultrasound is helpful in evaluating these masses most commonly appearing as oval, circumscribed, and hyperechoic. Clinical, radiological, and pathological information needs to be carefully evaluated as angiolipomas can be confused with malignant pathology. Three cases of angiolipomas of the male breast are reported in this study with mammographic, sonographic, and pathologic correlation...

Cellular angiolipoma is a rare subtype of angiolipoma, with vascular density approaching 95%. This case report describes a 55-year-old female that presented for treatment of a mass in her left breast that had been tender to slightly painful on palpation for nearly 2 years The patient underwent surgical excision of the mass, which was pathologically confirmed as a cellular angiolipoma. As of the 3-year follow-up, the patient reported no recurrence of the lesion. It is important to report this case and refresh knowledge of this and similar lesions to raise awareness of this diagnosis and treatment and improve future management of cellular angiolipoma cases...

Nevus lipomatosus cutaneous superficialis is a rare, benign hamartoma characterized by mature adipocyte proliferation in the dermis. It is frequently difficult to distinguish clinically from soft tissue tumors, including lipoma, neurofibroma, venous malformation, and angiolipoma. Notably, the classical form, which shows multiple and sometimes enlarged nodules, is difficult to differentiate from liposarcoma based on clinical examination, computed tomography, and magnetic resonance imaging findings. Therefore, to ascertain the utility of ultrasonography in diagnosing nevus lipomatosus cutaneous superficialis, sonographic examinations were performed on eight patients with nevus lipomatosus cutaneous superficialis...

A spinal epidural angiolipoma is a rare, benign tumor of adipocytes and blood vessels that accounts only for a small percentage of all spinal axis tumors. We report a case of a 44-year-old male who presented with three months of progressive decreased sensation and strength from about six cm above the umbilicus down to his feet bilaterally. He presented to the emergency room when he could no longer walk. He also had neurogenic urinary retention and likely neurogenic constipation. Physical exam was notable for decreased sensation, decreased strength, and increased patellar reflexes bilaterally...

A 75-year-old male patient visited Gangneung-Wonju National University Dental Hospital (Gangneung, South Korea) with a 35-mm fluctuant lesion on the floor of the mouth. It was a dome-shaped exophytic lesion with its top on Wharton's duct orifice area. The encapsulated lesion was excised cautiously and the final diagnosis was non-infiltrating angiolipoma. To the best of our knowledge, this is the first report of an intraoral approach for the treatment of a non-infiltrating angiolipoma on the floor of the mouth in an elderly patient...

A woman in her 50s presented to her general practitioner (GP) with an 8-month history of multiple painful subcutaneous nodules of various sizes in her trunk and limbs. Her previous GP made the clinical diagnosis of lipoma when they presented as non-painful nodules 2 years ago. Initial ultrasound demonstrated multiple lipomata with the largest size in the left upper thighs displaying features of subtle internal vascularity, entirely contained within the subcutaneous layer. MRI scan of thigh lesions showed multiple angiolipomas consistent with the entity of Dercum's disease...

Angiolipomas are slow-growing benign mesenchymal-derived tumors consisting of mature adipocytes and thin-walled blood vessels. While the majority of angiolipomas are found in subcutaneous tissues, rarely there are case reports of intracranial lesions. We present a case of cisternal angiolipoma in a 10-year-old female. She presented with vague symptoms like dizziness without neurological deficits and radiological evaluation confirmed a left-sided infratentorial cisternal partially enhancing mass. She underwent craniotomy and had complete resection of the mass, which was histologically composed of mature adipocytes and blood vessels, consistent with angiolipoma...

Esophageal angiolipoma is a rare disease with unspecific clinical manifestations.This paper reported a case of esophageal angiolipoma confirmed by upper gastrointestinal endoscopy and summarized the clinical manifestations,endoscopic and pathological features,treatment and prognosis of the patients by reviewing the relevant literature,aiming to provide references for clinical diagnosis and treatment of this disease in the future.

UNLABELLED: To document a case of an intraosseous angiolipoma (IOAL) of the humerus. CASE PRESENTATION: A 52-year-old woman presented with gradually increasing pain in her right arm. A X-ray series of the right elbow and computed tomography revealed a nonexpanding radiolucent lesion in the distal end of the right humerus. The fatty nature of the lesion was further verified using fat-suppression techniques on magnetic resonance imaging sequences. CLINICAL DISCUSSION: The tumor was surgically excised, and the patient has experienced no symptoms for 2 years now...

Duodenal angiolipoma is a rare adipocytic tumor, with non-specific symptoms precluding an early diagnosis. We present a case of a 67-year-old female admitted due to upper gastrointestinal bleeding. The upper endoscopy and endoscopic ultrasound evaluation showed a subepithelial lesion in the third portion of the duodenum. Endoscopic excision was performed using a standard polypectomy technique after endoloop placement. Histopathology was compatible with duodenal angiolipoma. The authors highlight duodenal angiolipoma as a rare adipocytic tumor potentially causing gastrointestinal bleeding, which can be safely treated with endoscopic excision...
