Chondroid Lipoma is a very rare and well-defined, benign fatty tumor. It is named so, because the fat cells are present in a cartilage background.

What are the other Names for this Condition? (Also known as/Synonyms)

  • Benign Chondroid Lipoma

What is Chondroid Lipoma? (Definition/Background Information)

  • Chondroid Lipoma is a very rare and well-defined, benign fatty tumor. It is named so, because the fat cells are present in a cartilage background
  • It is a slow-growing tumor that is observed predominantly in women, on the arms and legs
  • They are deep-seated and usually do not cause any signs and symptoms; they are also often painless
  • There are no identified risk factors or causative factors for Chondroid Lipoma, though certain chromosomal abnormalities have been observed
  • If the tumors are asymptomatic, then no treatment may be necessary. But, if required, a complete surgical excision of the Chondroid Lipoma may be performed
  • The prognosis is generally excellent, since these tumors are benign

Who gets Chondroid Lipoma? (Age and Sex Distribution)

  • Chondroid Lipoma is typically found in adult women (young and old); a wide age range has been observed (14-70 years)
  • Both females and males are affected, though the incidence of the condition is high in females (4:1 female-male ratio)
  • There is no racial or ethnic preference observed

What are the Risk Factors for Chondroid Lipoma? (Predisposing Factors)

  • The risk factors for Chondroid Lipomas are currently unknown or unidentified

It is important to note that having a risk factor does not mean that one will get the condition. A risk factor increases ones chances of getting a condition compared to an individual without the risk factors. Some risk factors are more important than others.

Also, not having a risk factor does not mean that an individual will not get the condition. It is always important to discuss the effect of risk factors with your healthcare provider.

What are the Causes of Chondroid Lipoma? (Etiology)

  • The exact cause of Chondroid Lipoma formation and development is unknown
  • Studies have shown the involvement of chromosomal abnormalities on chromosome 11

What are the Signs and Symptoms of Chondroid Lipoma?

The signs and symptoms of Chondroid Lipoma are:

  • The presence of a single, solitary slow-growing tumor, which may be painless; the tumor size may range from 2-11 cm
  • The tumor is benign and well-defined and composed of fatty tissue. It is usually observed deep inside the body (deep-seated tumor)
  • It may be observed at several locations of the body, such as the legs (thigh), arms, trunk (chest and back), head and neck region

How is Chondroid Lipoma Diagnosed?

Chondroid Lipoma is diagnosed using the following tools:

  • Complete physical examination with comprehensive evaluation of medical history
  • Radiographic studies, such as plain x-ray studies, CT or MRI scan of the affected region
  • Tissue biopsy: A tissue biopsy is performed and sent to a laboratory for a pathological examination. The pathologist examines the biopsy under a microscope. After putting together clinical findings, special studies on tissues (if needed) and with microscope findings, the pathologist arrives at a definitive diagnosis. The biopsy is generally performed to rule out other more severe conditions
  • A differential diagnosis may be used to eliminate other tumor types

Many clinical conditions may have similar signs and symptoms. Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis.

What are the possible Complications of Chondroid Lipoma?

There are no significant complications due to Chondroid Lipoma.

How is Chondroid Lipoma Treated?

Treatment measures for Chondroid Lipoma include the following:

  • If there are no symptoms, then conservative treatment may be employed. However, periodic observation is maintained and if there is any pain, it can be controlled through pain medication
  • Surgical excision with removal of the entire tumor is the standard treatment method used. If the lesion is not fully removed, then there are chances of its recurrence
  • Post-operative care is important: One must maintain minimum activity levels, until the surgical wound heals
  • Post-operative follow-up care with regular screening and check-ups are important

How can Chondroid Lipoma be Prevented?

Current medical research has not established a way of preventing Chondroid Lipoma.

What is the Prognosis of Chondroid Lipoma? (Outcomes/Resolutions)

  • Chondroid Lipomas are generally asymptomatic and these tumors may not require any treatment
  • The prognosis is generally excellent, when the tumors are small and are completely excised
