Basic information] Male, 32 years old [Type of disease] Epidermoid cyst [Hospital] Guangdong Provincial People’s Hospital [Date of consultation] October 2021 [Treatment plan] Surgical treatment (superficial mass excision surgery) [Treatment cycle] Outpatient treatment for 1 week, followed up by telephone after 1 month [Treatment effect] The mass was completely excised, and the incision was healed well without leaving obvious scars and no recurrence I. Initial consultation The patient was nervous. The patient was nervous and said that a rice grain-sized swelling appeared on her neck skin one month ago, which was painless and itchy. Initially, she thought that it was the symptom of “fire” caused by eating too much fried food, and it should subside on its own after drinking herbal tea, but instead of disappearing, the swelling got bigger and bigger and protruded up high, and she heard from her friends that the swelling might be a skin tumor, and so she came to the clinic for consultation. He was told by his friends that it might be a skin tumor, so he hurriedly came to see the doctor. Upon careful inspection of the patient’s skin, there was a peanut-sized smooth spherical swelling in the front of the neck, with clear boundary, good mobility, no pressure pain, and a needle-tip-sized hole in the center of the surface of the swelling, but the contents of the swelling could not be squeezed out. After visualization and palpation, it was initially judged to be a typical epidermoid cyst. The clinical diagnosis is told to the patient that it is a benign swelling and will not become malignant, but it may gradually increase in size and sometimes become infected and suppurative. If the cyst is small and remains unchanged for a long period of time, the patient can continue to observe it. If the cyst is large enough to affect its appearance and function, it should be surgically removed, and the wall of the cyst will be completely peeled off and removed in order to avoid recurrence in the future. After discussing with his family, the patient felt that although the swelling was not too big, it was located in the anterior neck area and was very conspicuous as a spherical bulge, so he asked for surgical excision. After signing the informed consent form, the patient was given a superficial lumpectomy under local anesthesia and the cyst was removed. Third, the therapeutic effect of superficial mass excision was successfully completed, the cyst was completely peeled off and removed during the operation, and the incision was closed with cosmetic suture. After the operation, the patient went to the outpatient clinic daily to change the medication, and the suture was successfully removed after 1 week, and the treatment cycle was completed. The patient’s incision healed well, there was no local infection such as redness, swelling, pus, etc., and the patient indicated that there was basically no pain. 1 month later, the patient said that there was no recurrence of the swelling, no local itching, no pain and other discomforts, and there was no obvious scar left behind. Precautions We are glad that the patient’s epidermoid cyst was successfully removed without recurrence. However, patients should be reminded that before the surgical site is completely healed, they should pay attention to local hygiene, keep clean and dry, and avoid strenuous exercise and eating spicy and stimulating food, so as not to stimulate the lesion and affect the healing. If the incision site appears local redness, swelling, pain, oozing, pain intensification and other signs of infection, it is necessary to go to the hospital in a timely manner, symptomatic treatment to avoid aggravation of the infection. V. Personal perception Epidermoid cysts are a common type of skin cysts that may gradually increase in size. The patient in this article belongs to a typical epidermoid cyst, which usually has no symptoms such as itching and pain, but redness, swelling and pain will occur when the cyst ruptures or secondary infection. Surgical excision is recommended when the swelling increases rapidly and affects aesthetics or function. After the operation, we should pay attention to take good care of the incision site, avoid moisture and infection, and prevent obvious scars after healing.
