Analysis of High-Frequency Ultrasound in the differential Diagnosis of Lumps in Foot and Hand

Objective: To investigate the ultrasonogram characteristics of common lumps in hand and foot, pursuing for greater understanding of hand and foot lumps. Methods: 65 cases of ultrasonographic characteristics of lumps in hand and foot were retrospectively analyzed, including the location, size, shape, boundary, internal echo and posterior echo, surrounding relationship and blood flow. Results: Among 65 cases, there were 26 cases of tendon sheath cyst, 16 cases of tenosynovitis giant cell tumor, 10 cases of hemangioma, 4 cases of tendon sheath fibroma, 3 cases of epidermoid cyst, 2 cases of Schwannoma, 2 cases of fibrolipoma, 1 case of angiolipoma and 1 case of neurofibroma. The preoperative and postoperative pathological diagnoses of 45 cases, accounting for 69.23%, were consistent, 3 cases (4.62%) were misdiagnosed, which included that 2 cases of tenosynovitis giant cell tumor were misdiagnosed as tendon sheath cyst, 1 case of neurofibroma as epidermoid cyst, and the preoperative diagnosis of the rest 17 cases(26.15%) were indefinite. Conclusion: The high-frequency ultrasound can diagnose properties of lumps in foot and hand well, providing diagnosis basis for further treatment in clinic.

Unique Case of 32-Year-Old Male Presenting with Angiolipoma of an ACL Hamstrings Autograft

Angiolipoma is a histological variant of the more common lipoma that may occur superficially throughout the body. After review of recent literature, different cases of angiolipomas were reported within various areas, more so in the upper extremity and truncal regions.

Endoscopic Submucosal Dissection of the Angiolipoma at Hypopharynx-Esophageal Introitus.

Angiolipoma in the region of the hypopharynx-esophageal introitus is a rare occurrence. Surgical treatment was performed in the few cases reported in the literature. Endoscopic submucosal dissection (ESD) is a minimally invasive treatment for hypopharyngeal and esophageal lesions. Our objective was to evaluate the feasibility, safety, and efficacy of ESD for treatment of angiolipoma at the hypopharynx-esophageal introitus. The patients with submucosal tumors at the hypopharynx-esophageal introitus were diagnosed as angiolipoma by preoperative evaluation with endoscopy, endoscopic ultrasonography, and computed tomography (CT). The patients who were diagnosed with angiolipoma agreed to undergo endoscopic submucosal dissection. Under general anesthesia and endotracheal intubation, ESD was used to remove the lesions. Preoperative, intraoperative, and postoperative data were collected and analyzed to evaluate the feasibility, safety, and effectiveness of endoscopic submucosal dissection. From January 2013 to December 2018, 6 cases of angiolipoma were treated with ESD with a success rate of 100%. The average operation time was 107.0 ± 69.4 minutes. Intraoperative blood loss is the main risk. Endoscopic thermocoagulation successfully stopped bleeding in all cases. Pharyngeal pain and painful swallowing were the main clinical signs. There was no stricture at the hypopharynx-esophageal introitus after the operation. ESD treatment of angiolipoma at hypopharynx-esophageal introitus is feasible, safe, and effective.

Bronchial angiolipoma successfully treated by sleeve resection of the right bronchus intermedius: a case report

BackgroundAngiolipoma is a rare, benign tumor that primarily develops in the limbs and trunk. The occurrence of angiolipoma in the lungs is extremely rare; to date, only two cases of primary bronchial angiolipoma have been reported. Here, we report a case of angiolipoma of the right bronchus intermedius that was successfully treated with sleeve resection and reconstructive surgery.Case presentationThis report presents a case of angiolipoma that developed in the right bronchus intermedius of a 68-year-old man. A chest CT revealed a 10-mm endobronchial mass that was clearly visible as a high-attenuation area of contrast enhancement. Bronchoscopy revealed a submucosal tumor on the anterior wall of the entrance to the right bronchus intermedius that was constricting the airway lumen. The tumor surface was covered with numerous engorged blood vessels, and the middle and inferior pulmonary lobes were intact. Bronchial sleeve resection of the right bronchus intermedius was performed. Histologically, a mixture of proliferating blood vessels and adipocytes were observed within the bronchus wall. Therefore, the pathological diagnosis was angiolipoma. Lung function was preserved, and complete resection of the tumor was achieved. At present (2 years and 7 months after surgery), the patient is recurrence-free.ConclusionAccordingly, using bronchial sleeve resection and end-to-end anastomosis techniques, we accomplished complete tumor excision and avoided the need to resect additional lung parenchyma. Our procedure preserved pulmonary function and yielded a curative result. Bronchoscopic intervention or minimal parenchymal resection should be considered as treatments for bronchial angiolipoma. Given the small number of reports of bronchial angiolipoma, the collection of additional data is important to elucidate the clinical characteristics of this rare tumor.

Angiolipoma of the mammary region: A report of two cases

Angiolipoma is a benign variant of lipoma that is rare in the breast and may be confused clinically, radiologically and pathologically with other benign tumours. It accounts for 5 - 17% of all benign fatty tumours. Clinicians, radiologists and pathologists in particular should not forget the existence of an angiolipoma of the breast to avoid unnecessary re-aspiration of the lesion considering the smears with only adipose tissue fragments as inadequate. We report two cases of angiolipoma who presented with solitary lumps in the breast, and a clinical diagnosis of fibroadenoma was suggested in both the cases. Both were diagnosed as lipoma on cytology and, on subsequent histopathology, a diagnosis of angiolipoma was given.

Angiolipoma in sellar, suprasellar and parasellar region: report on two new cases and review of literature

Angiolipomas of CNS are very rare; more than 90% involve the spinal canal. There are only a few case reports documenting the tumor in the sellar/suprasellar region. We report 2 cases of angiolipoma involving sellar/suprasellar and right parasellar region in two female patients. On histopathology the lesion was composed of vascular component which was of cavernous type in one patient and of capillary caliber in the other with admixture of mature adipocytes. The MRI findings were distinctive as the lesion was predominantly iso-to-hypointense on T1W sequence, hyperintense on T2WI and FLAIR sequence. In addition, a few small hyperintense areas were noted on plain T1W images which may represent intralesional fat. One of the cases also showed lipid lactate peak on MR spectroscopy. To the best of our knowledge only 8 other cases of sellar, parasellar angiolipomas have been reported in indexed literature. MRI with fat suppression sequences should be routinely performed in lesions in such locations with hyperintense areas on T1WI as the incidence of intraoperative blood loss is very high. A preoperative suspicion of the diagnosis might help in reducing the patient morbidity.

Posterior Mediastinal Angiolipoma that Presented with Pleural Effusion

Angiolipoma is a rare benign tumor composed of mature adipose tissues and blood vessels. It is usually located in the subcutaneous tissue of the trunk, the extremities and the neck, and few cases of angiolipoma have been reported in the mediastinum. We report here on a rare case of posterior mediastinal angiolipoma that presented with pleural effusion.

Primary Intranodal Cellular Angiolipoma

Angiolipoma is a distinct, benign soft tissue tumor that most commonly occurs in young males as multiple small, subcutaneous, tender to painful nodules with predilection for the forearms. We report a case of angiolipoma that developed within a lymph node. The patient was a 67-year-old man who underwent radical retropubic prostatectomy with diagnostic pelvic lymphadenectomy because of adenocarcinoma of the prostate. The prostate and 3 lymph nodes located in the obturator fossa were removed. On gross examination, the cut surface of 1 of the lymph nodes revealed an 8 x 5 mm, ovoid, sharply demarcated, nonencapsulated, gray lesion being suspicious for adenocarcinoma metastasis. Microscopically, the major portion of the lymph node was replaced by mature metaplastic adipose tissue. The angiolipoma was seen as a well-demarcated, nonencapsulated lesion composed of numerous small blood vessels lined by monomorphous flattened or spindled endothelial cells. Many vascular lumina were filled with fibrin thrombi. There were scanty mature adipocytes. Focally, areas with increased cellularity and a suggestion of solid growth of the endothelial cells were seen. Lymph nodes are known to be a rare primary site of various tumors usually occurring in other organs. The knowledge of these tumors is important in order not to interpret them as metastatic lesions. The most recognized examples are pigmented nevi, palisading myofibroblastoma, various benign epithelial inclusions, serous cystic tumors of borderline malignancy, and hyperplastic mesothelial inclusions. As we present in this report, angiolipoma is another neoplasm whose primary occurrence in the lymph node should not be misinterpreted as a metastatic tumor or malignant vascular tumor.
