Palmar Fibromatosis

Palmar fibromatosis, also known as Dupuytren’s contracture, is a condition characterized by the progressive thickening and contracture of the palmar fascia, a layer of tissue located beneath the skin of the palm and fingers. This condition can lead to the formation of nodules or cords, resulting in the curling of the fingers towards the palm. In this article, we will explore the definitions, types, and treatment options for palmar fibromatosis.

Palmar fibromatosis is a fibroproliferative disorder that primarily affects the palmar fascia of the hand. It is characterized by the abnormal proliferation of fibroblast cells and the deposition of excessive collagen, leading to the formation of nodules or cords within the palmar fascia. Over time, these nodules can contract, causing a progressive limitation in finger movement and potential disability.

Types of Palmar Fibromatosis

1. Nodular Palmar Fibromatosis: Nodular palmar fibromatosis is the most common type of palmar fibromatosis. It is characterized by the formation of small, painless nodules or lumps within the palmar fascia. These nodules are usually located on the palm, near the base of the fingers. Initially, they may be soft and movable, but as the condition progresses, they can become firm and fixed.
2. Dupuytren’s Contracture: Dupuytren’s contracture is an advanced stage of palmar fibromatosis. It is characterized by the thickening and contracture of the palmar fascia, resulting in the curling of one or more fingers towards the palm. This condition typically affects the ring finger and little finger but can involve other fingers as well. The progression of Dupuytren’s contracture varies among individuals, and it may cause difficulty in performing everyday tasks.

Causes

Common causes of palmar fibromatosis, providing a detailed explanation of each.

1. Genetic Factors: Genetics play a significant role in the development of palmar fibromatosis. It tends to run in families, and certain genetic variations increase the risk of developing this condition.
2. Age: Palmar fibromatosis typically affects individuals over the age of 50. As people get older, the risk of developing this condition increases.
3. Gender: Men are more prone to developing palmar fibromatosis compared to women. The reason behind this gender difference is not yet fully understood.
4. Ancestry: Individuals of Northern European or Scandinavian ancestry have a higher incidence of palmar fibromatosis. This suggests a potential role of genetic factors specific to certain populations.
5. Family History: Having a family history of palmar fibromatosis significantly increases the risk of developing the condition. If a close family member has had it, the likelihood of developing it increases.

Symptoms

Common symptoms of palmar fibromatosis

1. Nodule Formation: Palmar fibromatosis often starts with the formation of small, painless nodules or lumps beneath the skin of the palm. These nodules can be felt and are usually firm to the touch.
2. Finger Flexion Contracture: As the condition progresses, the fingers gradually bend inward, towards the palm. This flexion contracture makes it difficult to straighten the affected fingers fully.
3. Palmar Thickening: Palmar fibromatosis leads to the thickening of the skin on the palm. The skin may feel tough and develop a cord-like texture.
4. Hand Stiffness: Individuals with palmar fibromatosis may experience stiffness in their hand, making it challenging to perform tasks that require fine motor skills.
5. Finger Curling: The affected fingers may curl or flex involuntarily, even when at rest. This curling can become more pronounced over time.
6. Finger Extension Difficulty: Patients may find it increasingly difficult to extend their fingers fully due to the tightening of the connective tissue.
7. Pitting: The skin over the nodules may develop shallow pits or dents, which can be seen on the palm’s surface.
8. Pain or Discomfort: In the early stages, palmar fibromatosis is usually painless. However, as the condition progresses, some individuals may experience discomfort or mild pain.
9. Reduced Grip Strength: The tightening of the palm and fingers can lead to a decrease in grip strength, making it challenging to grasp objects firmly.
10. Limited Dexterity: Patients may find it difficult to perform intricate tasks that require finger dexterity, such as typing, playing a musical instrument, or sewing.
11. Difficulty Placing Hand Flat on Surface: As the fingers contract, it becomes increasingly challenging to lay the hand flat on a surface, with the fingers resting naturally.
12. Tethering of Skin: The nodules and thickened tissue can cause the skin to feel tethered or bound down, limiting the hand’s range of motion.
13. Thumb Involvement: Although palmar fibromatosis primarily affects the palm and fingers, the thumb can also be involved, leading to restricted movement and function.
14. Recurrence: After surgical intervention or treatment, some patients may experience a recurrence of palmar fibromatosis. New nodules and symptoms may appear over time.
15. Slow Progression: The symptoms of palmar fibromatosis typically progress gradually over months or years, with varying rates of progression for each individual.
16. Bilateral Involvement: The condition can affect both hands simultaneously, leading to bilateral symptoms and limitations in hand function.
17. Difficulty Wearing Gloves: As the fingers become progressively contracted, wearing gloves can become challenging or impossible due to the hand’s altered shape.
18. Difficulty Shaking Hands: The presence of nodules, finger contracture, and limited hand mobility can make it difficult to shake hands or perform simple gestures.
19. Emotional Impact: Palmar fibromatosis can have emotional and psychological effects due to the progressive loss of hand function and its impact on daily activities.

Diagnosis

Common diagnostic methods and tests used to identify palmar fibromatosis.
