A man has a wart on his neck.

The neck refers to the cervical region. In men, the appearance of skin growths on the neck is usually caused by conditions such as filiform warts, common warts, or flat warts. Prompt medical evaluation and treatment based on the underlying cause are recommended. Specific analyses are as follows:

1. Filiform Warts

When filiform warts occur on the neck, they manifest as slender, soft, thread-like skin projections. These typically cause no significant discomfort but are somewhat contagious. Under a doctor's guidance, patients may apply topical medications such as tretinoin cream or salicylic acid ointment to alleviate symptoms.

2. Common Warts

Commonly caused by infection with human papillomavirus (HPV), these warts appear on the neck as brownish or skin-colored rashes, generally without other noticeable symptoms. With medical guidance, patients can use topical treatments such as imiquimod cream or Wumiao Shuixian ointment.

3. Flat Warts

Flat warts are caused by HPV type 3 infection and present as small, grain-to-pea-sized bumps on the neck, sometimes accompanied by mild foreign body sensation or itching. Patients should, under medical supervision, use medications such as acyclovir cream or recombinant human interferon α2b gel to relieve symptoms.

In addition to the above common causes, other conditions such as genital warts, epidermal fibromas, or lipomas may also be responsible. Individuals experiencing abnormal skin changes should seek timely medical attention to avoid delayed diagnosis and treatment.
