surfer nodule
Introduction
Surfer nodule introduction Surfer 'sknots are subcutaneous nodules that occur on the surfers' knees and back of the feet. When surfing, the surfboard often rubs against the athlete's knees and the back of the foot, which causes the skin to thicken here. In addition, the disease seems to have a certain relationship with the cold stimulation during seawater movement. Bone fragments or bone spurs can occur under the dorsal nodules of the affected area, which is a long-term bone change caused by nodular compression. basic knowledge The proportion of illness: 0.003% Susceptible people: no specific people Mode of infection: non-infectious Complications: heel freckle
Cause
Surfer nodule cause
Cause:
Mainly during surfing, the surfboard often rubs against the athlete's knees and the back of the foot, which leads to thickening of the skin here. In addition, the disease seems to have a certain relationship with the cold stimulation during seawater movement.
Prevention
Surfer nodule prevention

It can protect the knees and the back from the friction of the surfboard during surfing, such as changing the posture or wearing elastic sponge rubber in the vulnerable parts. Pads, etc. Patients who have already had surfers' nodules should stop surfing, and local massage, hot compress, and moxibustion can alleviate symptoms and promote healing.
Complication
Surfer nodule complications Complications, heel freckles
Long-term compression by the nodules can cause bone changes.
Symptom
Surfer nodule symptoms common symptoms granuloma calcified nodules epidermal keratinization
The skin lesions are located in the knee and the back of the foot. The skin lesions start from the soft nodules of the affected area. The skin of the affected area is red, with obvious pain and undulation. After the ulceration, the transparent or turbid liquid is discharged. After repeated surfing for 1 to 2 years. The friction and nodules become solid fibrous masses. At this time, the pain is relieved or disappeared. Bone fragments or bone spurs may occur under the nodules of the affected foot. This is a long-term bone change caused by nodular compression.
Examine
Surfer nodule inspection
The disease is mainly based on the characteristics of the rash examination, the lesion is located in the knee and the back of the foot. The skin lesions start from the soft nodules of the affected area, the skin of the affected area is red, there is obvious pain, and there is a sense of fluctuation. After the ulceration, the transparent or turbid liquid is discharged. At the same time, combined with the hobby of the patient, the diagnosis can be confirmed. Histopathological features were nodular granuloma with epidermal hyperkeratosis and epidermal hyperplasia, no calcification of nodules.
Diagnosis
Surfer nodule diagnosis
Surfers or athletes, thickening of the skin on both knees and back, soft nodules in the affected area, redness of the affected area, bone fragments or spurs under the dorsal nodules of the affected area, histopathology: nodules with proliferative granuloma with epidermal horn Over-exposure and epidermis flattened, no calcification of nodules, can be diagnosed.
