Cutaneous lipomas are rare in children, but these tumors can occur as part of the inherited disease Bannayan-Zonana syndrome. [40] [41] Lipomas are usually relatively small with diameters of about 1–3 cm, [42] but in rare cases they can grow over several years into "giant lipomas" that are 10–20 cm across and weigh up to 4–5 kg. [43] [44]
Common examples of benign tumors include moles and uterine fibroids. Some forms of benign tumors may be harmful to health. Benign tumor growth causes a mass effect that can compress neighboring tissues. This can lead to nerve damage, blood flow reduction , tissue death , or organ damage.
Symptoms include pain in the abdomen or flank, blood in the urine, a palpable lump or high blood pressure. [1] As they are benign tumors, myelolipomas do not spread to other body parts. Larger myelolipomas are at risk of localised tissue death and bleeding, which may cause a retroperitoneal haemorrhage. [1]
Hepatocellular adenoma (also known as hepatic adenoma or hepadenoma) is a rare, benign liver tumor. It most commonly occurs in people with elevated systemic levels of estrogen , classically in women taking estrogen-containing oral contraceptive medication.
Most people with benign angiomyolipomas do not show signs or have symptoms. However, symptoms can occur if the dilated blood vessels in an angiomyolipoma rupture; this is called a retroperitoneal hemorrhage. This can cause pain in the back, nausea and vomiting. Some long-term effects are anemia, hypertension, and chronic kidney disease.
The ovarian fibroma, also fibroma, is a benign sex cord-stromal tumour. Ovarian fibromas represent 4% of all ovarian neoplasms. [1] They tend to occur mostly during perimenopause and postmenopause, the median age having been reported to be about 52 years, and they are rare in children. [1] Lesions tend to be asymptomatic.
Treatment depends on the underlying cause. [1] It may vary from simple pain medication to surgical removal. [1] Some causes may resolve without treatment. [4] Breast masses are relatively common. [2] It is the most common breast complaint with the women's concern generally being that of cancer. [5] [6]
Treatments for solitary osteochondroma are careful observation over time and taking regular x-rays to monitor any changes in the tumor. [11] If the lesion is causing pain with activity, nerve or vessel impingement, or if the bone growth has fully matured and the presence of a large cartilage cap is prominent, then it is advised that the tumor ...
