Case presentation This report presents a case of angiolipoma that developed in the right bronchus intermedius of a 68-year-old man. [bmcsurg.biomedcentral.com]

In January of 2018, he underwent right knee arthroscopy, about 4 months after his initial presentation. [clinmedjournals.org]

In the present case, VEGF-A and -B, which are known to stimulate the formation of blood vessels in tumors, were expressed. [spandidos-publications.com]

We present two cases of SEAL which we successfully surgical resected with no further neurological deficits. Case presentation Case 1 We present a case of 39-year-old woman with 6-month history of numbness at the low extremities. [jss.amegroups.com]

• Soft Tissue Mass

  In Figure 7, Figure 8 and Figure 9, small blood vessels were present within the soft tissue mass, identified by their smooth muscle walls. [clinmedjournals.org]

  As the tumor was unencapsulated, the normal tissue surrounding the tumor was extirpated. The excised specimen revealed a solid soft-tissue mass (20×19×10 mm) with a dark yellow surface (Fig. 2). [spandidos-publications.com]

  Physicians and orthopedic/general surgeons should be aware of the possibility of soft tissue masses in a posttrauma situation. 1. [hindawi.com]

• Inflammation

  The second theory based on studies with encapsulated lipomas without lesions in Scarpa’s fascia [19–21] suggests that the induction of the differentiation of mesenchymal precursors (preadipocytes) to mature adipocytes and the effect of local/systemic inflammation [hindawi.com]

• Cough

  Due to the indolent nature of this neoplasm, symptoms of bronchial obstruction, such as coughing, wheezing, dyspnea, sputum production, hemoptysis, atelectasis, and pneumonia, may be observed in these patients. [bmcsurg.biomedcentral.com]

• Hypertension

  Past medical history included arterial hypertension. In addition, he was a social drinker and a nonsmoker. Physical examination revealed a large, palpable, and painless soft solid mass on the upper half of the right forearm (Figure 1). [hindawi.com]

• Prolapse

  The first “mechanical effect” of trauma theory [17, 18], suggests that acute or repeated trauma leads to a prolapse of adipose tissue through Scarpa’s fascia forming a pseudolipoma (not a true lipoma because it is not encapsulated). [hindawi.com]

• Subcutaneous Nodule

  It occurs more frequently in younger individuals as a painful subcutaneous nodule, often on the arms. [ NCIT : P378 ] Synonyms: angiolipoma angiolipoma, benign [ebi.ac.uk]

  Angiolipoma accounts for 5–17% of all lipomas and predominantly presents as subcutaneous nodules in young adults, which are tender or painful on palpation, particularly during the initial growth period. [spandidos-publications.com]

  Clinically, the encapsulated/noninfiltrative angiolipoma presents as a subcutaneous nodule: the lesions are commonly multiple, typically firm, tender to palpation but often painful, and rarely associated with overlying skin changes [2, 5, 9, 10]. [hindawi.com]

• Subcutaneous Mass

  These subcutaneous masses can occur anywhere on the body but are most often found on the neck, trunk, and extremities, with up to two-thirds occurring on the forearm. [clinmedjournals.org]

  Neck ultrasound (US) examination, conducted in August 2006 and May 2007, revealed a well-defined solid hypo-echogenic subcutaneous mass located in the right mandibular angle, 0.93 × 2.52 cm in size. [mdpi.com]

A combine treatment with surgery and radiotherapy has also been used by Gonzalez-Crussi et al. with success (10,16). [jss.amegroups.com]

Management and Treatment How are angiolipomas treated? Angiolipomas don’t go away on their own. However, unless an angiolipoma causes pain or discomfort, you don’t have to treat it. [my.clevelandclinic.org]

Treatment of angiolipoma Surgery is curative, but not essential as these lesions are benign. Angiolipomas tend to be well-circumscribed and easily removed. [dermnetnz.org]

The “Gold standard” treatment is excision with clear margins and bleeding management should be taken into account according to appropriate differential diagnosis. [mdpi.com]

Outlook / Prognosis What can I expect if I have angiolipomas? With proper diagnosis and treatment, the outlook for people with angiolipomas is good. [my.clevelandclinic.org]

Infiltrating angiolipoma has a recurrence rate of 50%, however a good prognosis can be expected with radiotherapy and additional excision. On the other hand, non-infiltrating angiolipoma shows no tendency to recurrence [2, 12, 13]. [surgicalcasereports.springeropen.com]

The overall prognosis for angiolipoma is good, as no malignant potential transformation has been reported [20,21]. [mdpi.com]

The etiology of angiolipoma is a matter of debate, though post-pubertal hormonal influence and repetitive microtrauma have been theorized to play a role in its origin [1,2]. [clinmedjournals.org]

The pathogenesis of angiolipomas is still unclear, but acute or recurrent trauma has been suggested as a possible etiologic factor [1, 4, 5]. [hindawi.com]
