Pea size lumps on the neck can be a cause for concern and raise a multitude of questions. While it's easy to assume that such lumps are related to underlying issues within the neck itself, it's important to recognize that the skin covering the neck can also play a significant role. This blog delves into the intriguing realm of skin-related causes of pea-size lumps on the neck.

Throughout this blog, we will explore several skin-related causes of pea size lumps on the neck, ranging from benign conditions to those that may require medical attention. We will discuss sebaceous cysts, lipomas, dermatofibromas, skin infections, as well as moles, and skin tags. By gaining a deeper understanding of these conditions, you will be better equipped to assess the potential causes of the lumps and make informed decisions about seeking medical advice.


Sebaceous Cysts

Sebaceous cysts are common skin-related causes of pea size lumps on the neck. These cysts form when the sebaceous glands, which produce oil to lubricate the skin and hair, become blocked or damaged. The trapped oil and skin cells then accumulate, leading to the formation of a cyst.

Sebaceous cysts on the neck typically appear as painless, round, and movable lumps beneath the skin. They may vary in size and often have a characteristic whitish or yellowish appearance. While sebaceous cysts are usually harmless, they can become inflamed or infected if they rupture or are subjected to trauma.

Medical intervention may be necessary if a sebaceous cyst on the neck becomes bothersome or infected. Treatment options include:

Incision and Drainage: In cases of infection or discomfort, a healthcare professional can make a small incision in the cyst and drain the accumulated material. This relieves symptoms and promotes healing.

Excision: Complete sebaceous cyst removal is recommended if it is recurrent, growing rapidly, or causing persistent symptoms. A healthcare professional will perform a minor surgical procedure to excise the cyst and ensure complete removal.



Lipomas are another common cause of pea size lumps on the neck. They are noncancerous growths composed of fat cells that develop within the subcutaneous tissue. Lipomas are usually soft, movable, and painless.

Although lipomas can occur anywhere on the body, they are commonly found on the neck. These lumps may gradually increase in size over time. While lipomas are typically benign and do not require treatment, they can be surgically removed if they become symptomatic or have cosmetic concerns.


Treatment options for neck lipomas include:

Observation: If the lipoma is small, asymptomatic, and not causing any functional or cosmetic issues, a "wait and watch" approach may be adopted. Regular monitoring by a healthcare professional ensures that any changes in size or symptoms are promptly addressed.

Surgical Excision: Surgical removal may be recommended if the lipoma becomes bothersome or cosmetically undesirable. This involves making an incision, removing the lipoma, and closing the incision with sutures. Lipoma removal is a straightforward procedure, typically performed under local anesthesia.



Dermatofibromas are small, benign skin growths that can develop on the neck. They are typically firm, raised, and reddish-brown in color. Dermatofibromas are often the result of a reaction to an insect bite, injury, or other trauma to the skin.

These lumps may be asymptomatic or may cause mild itching or tenderness. In most cases, dermatofibromas do not require treatment and can be left alone. However, if the dermatofibroma becomes painful, itchy, or is cosmetically concerning, treatment options may include:

Topical Steroids: Applying topical corticosteroids can help alleviate any itching or discomfort associated with the dermatofibroma.

Surgical Excision: If the dermatofibroma is causing persistent symptoms or is cosmetically bothersome, a dermatologist may recommend surgical removal. The procedure involves cutting out the dermatofibroma and closing the wound with sutures.


Skin Infections

Skin infections can also give rise to pea size lumps on the neck. Common infections include folliculitis, abscesses, and cellulitis. These infections can occur when bacteria or fungi invade the skin, often through a break or cut in the skin's surface.

Folliculitis is an infection of the hair follicles and may cause small, red, and tender bumps on the neck. Abscesses are localized collections of pus that can develop as a result of a deeper skin infection. Cellulitis is a bacterial infection characterized by redness, warmth, swelling, and pain in the affected area.


Treatment for skin infections on the neck may include:

Antibiotics: Depending on the type and severity of the infection, oral or topical antibiotics may be prescribed to eliminate the underlying bacterial or fungal infection.

Incision and Drainage: In the case of an abscess, a healthcare professional may need to make an incision to drain the pus and alleviate symptoms.


Diagnosis and Treatment

Diagnosing the exact cause of a pea size lump on the neck requires a comprehensive evaluation by a healthcare professional, typically a dermatologist. During the examination, the healthcare professional will consider various factors, including the lump's appearance, location, and associated symptoms.


Diagnostic methods that may be employed include:

Physical Examination: A thorough examination of the lump and the surrounding skin will be performed to assess its characteristics, such as size, shape, color, texture, and tenderness.

Imaging Techniques: In some cases, imaging tests such as ultrasound or MRI may be used to obtain more detailed information about the lump's structure and location.

Biopsy: If there is uncertainty regarding the lump's nature, a biopsy may be recommended. A small tissue sample from the lump will be collected and examined under a microscope to determine its composition and rule out malignancy.



Pea size lumps on the neck can arise from various skin-related causes, including sebaceous cysts, lipomas, dermatofibromas, skin infections, moles, and skin tags. While many of these causes are benign, some may require medical intervention.

Understanding these skin-related causes can provide peace of mind and guide individuals in making informed decisions about seeking medical advice. Consulting ENT LDN for a proper evaluation is crucial to accurately diagnose the underlying cause of the lump and determine the most appropriate treatment approach.
