What is Squamous Cell Papilloma?

Squamous cell papilloma, also known as squamous papilloma or oral papilloma, is a small benign (non-cancerous) growth that begins in squamous cells, which are thin, flat cells found in the tissue that forms the surface of the skin and mucous membranes. These growths can occur on various parts of the body, including the skin, mouth, throat, and esophagus.

Characteristics

• Squamous cell papillomas are typically small, wart-like growths.
• They are usually painless and do not cause any discomfort.
• These growths are composed of squamous cells that form papillary or filiform structures.
• They can occur on the inside of the cheek, tongue, lips, palate, and other areas of the mouth.

Types

Squamous cell papillomas can occur in different parts of the body:

• Oral squamous papilloma: This type occurs in the mouth and is usually found on the inside of the cheek, tongue, or lips.
• Nasal squamous cell papilloma: This type occurs in the nasal passages and can originate from transitional, respiratory, or metaplastic olfactory epithelium.
• Esophageal squamous papilloma: This type occurs in the esophagus and is a rare condition.

Causes

The exact cause of squamous cell papillomas is not fully understood. However, it is believed that human papillomavirus (HPV) may play a role in the development of these growths.

Symptoms

Squamous cell papillomas are usually asymptomatic and do not cause any discomfort. However, if they interfere with eating or speaking, they may need to be treated.

Treatment

Most squamous cell papillomas do not require treatment unless they become symptomatic or interfere with daily activities. Treatment options include surgical removal, laser therapy, or observation.

Squamous cell papilloma, also known as squamous papilloma or benign esophageal squamous papillomas (BESPs), typically do not cause symptoms until they are large and cause trouble swallowing. However, when there is substantial overgrowth, it could present with some discomforting symptoms such as:

• Discomfort
• Difficulty swallowing

These symptoms can occur when the growth becomes large enough to cause irritation or obstruction in the esophagus.

In some cases, squamous cell papilloma may also be associated with other symptoms, including:

• Foreign body sensation
• Irritation
• Bleeding (in rare cases)

It's worth noting that these symptoms are usually not present until the growth becomes large enough to cause problems. In many cases, squamous cell papilloma is asymptomatic and does not cause any noticeable symptoms.

Squamous cell papilloma, also known as benign epithelial neoplasm, can be diagnosed through various diagnostic tests.

• Physical examination: A physical exam by a healthcare professional is the first step in diagnosing squamous cell papilloma. The doctor will examine the affected area to look for any visible signs of the condition.
• Skin biopsy: A skin biopsy is a minor surgical procedure where a small sample of tissue from the affected area is removed and examined under a microscope. This test can help confirm the diagnosis of squamous cell papilloma (7).
• Imaging tests: Imaging tests such as X-rays, CT scans, or MRI scans may be ordered to rule out other conditions that may have similar symptoms.
• Histopathological examination: A histopathological examination of the biopsy sample is essential in diagnosing squamous cell papilloma. The examination will reveal the characteristic features of the condition, including well-circumscribed exophytic papilliform and cauliflower-shaped mass (7).

It's worth noting that squamous cell papilloma is a benign condition, and the diagnosis is typically made based on histopathological examination of the biopsy sample.

Treatment Options for Squamous Cell Papilloma

Squamous cell papilloma can be treated using various methods, including:

• Destructive treatments: These medications work to destroy the tissue for removal. Examples include:
  • Cantharidin: a blistering agent that causes the skin to peel off, taking the papilloma with it [4].
  • Salicylic acid: a topical treatment that helps break down the tissue and remove the papilloma [4].
• Virucidal treatments: These are chemical agents that attack viral infections. Examples include:
  • Cidofovir: an antiviral medication used to treat viral infections, including those caused by human papillomavirus (HPV) [7].
  • Interferon-alpha: a protein that helps fight off viral infections and can be used to treat HPV-related conditions [7].
• Antimitotic treatments: These drugs block cell growth to rid the body of skin papillomas. Examples include:
  • Bleomycin: a chemotherapy medication that can be used to treat certain types of cancer, including squamous cell carcinoma [6].
  • Podophyllotoxin: a plant-based medication that can be used to treat viral warts and other skin conditions [4].
  • 5-fluorouracil: a chemotherapy medication that can be used to treat various types of cancer, including squamous cell carcinoma [6].

Other Treatment Options

In addition to these medications, other treatment options for squamous cell papilloma include:

• Surgical removal: the most effective treatment option for many cases of squamous cell papilloma, which involves surgically removing the affected tissue [11].
• Cryosurgery: a procedure that uses liquid nitrogen to freeze and destroy the affected tissue [15].
• Laser ablation: a minimally invasive procedure that uses a laser to remove the affected tissue [15].

It's essential to consult with a healthcare professional to determine the best course of treatment for an individual case of squamous cell papilloma.

Differential Diagnosis of Squamous Cell Papilloma

Squamous cell papilloma, a benign growth that begins in squamous cells, has several differential diagnoses to consider. These include:

• Verruciform xanthoma: A rare condition that can resemble squamous cell papilloma in appearance, but is characterized by the presence of xanthoma cells.
• Papillary hyperplasia: A benign growth that can appear similar to squamous cell papilloma, but is typically larger and more irregular in shape.
• Condyloma acuminatum: A sexually transmitted infection that can cause a growth on the skin or mucous membranes, which may be mistaken for squamous cell papilloma.
• Verruca vulgaris: A common viral infection that causes warts, which can appear similar to squamous cell papilloma in some cases.

According to [1], verruciform xanthoma has a predilection for the gingiva and alveolar ridge, while condylomas are larger than papillomas with broader bases and appear pink to red. [5] also mentions that the differential diagnosis of solitary oral squamous papilloma includes verruciform xanthoma, papillary hyperplasia, and condyloma acuminatum.

In addition, other conditions such as verrucous carcinoma, squamous papilloma, lymphoma, or lymphoepithelioma may also be considered in the differential diagnosis of squamous cell papilloma. [6]

It's essential to note that a definitive diagnosis can only be made through histopathological examination and clinical correlation.
