Since the diseased area (lesion) is not encapsulated, clinical margins are difficult to define. As such, portions of the diseased tissue may be left in the foot after surgery. Inadequate excision is the leading cause of recurrence. [2] [8] Radiotherapy has been shown to reduce the size of the nodules and reduce the pain associated with them.
They usually occur just under the skin, but occasionally may be deeper. [1] Most are less than 5 cm (2.0 in) in size. [2] Common locations include upper back, shoulders, and abdomen. [4] It is possible to have several lipomas. [3] The cause is generally unclear. [1] Risk factors include family history, obesity, and lack of exercise.
They present as multiple small or large bumps characteristically on the heels and wrists. [2] Most are asymptomatic and pain is rare, although some may present with pain before the bumps are noticed. [3]
Some hematomas are visible under the surface of the skin (commonly called bruises) or possibly felt as masses or lumps. Lumps may be caused by the limitation of the blood to a sac, subcutaneous or intramuscular tissue space isolated by fascial planes. This is a key anatomical feature that helps prevent injuries from causing massive blood loss.
Haglund's deformity is an abnormality of the bone and soft tissues in the foot. An enlargement of the bony section of the heel (where the Achilles tendon is inserted) triggers this condition. The soft tissue near the back of the heel can become irritated when the large, bony lump rubs against rigid shoes.
The source of this disease is from family history, and symptoms most often arise in middle age. [2] [3] Newly formed lipomas frequently present themselves as a bead-like lump under the skin, and become rubbery and movable. [3]
The first visible symptom of mycetoma is a typically painless swelling beneath the skin; over several years, this will grow to a nodule (lump). [9] Affected people will experience massive swelling and hardening of the area, in addition to skin rupture and the formation of sinus tracts that discharge pus and grains filled with organisms.

Diagnosis is typically based on examination. The ability to shine through the bump or any past decrease in size supports the diagnosis of the bump as a ganglion cyst. [4] Ganglion cysts are usually obvious upon observation. Medical imaging may be considered on infrequent occasions to rule out another diagnosis. [3] [4] Treatment is not necessary.
