verruciform xanthoma of skin

Verruciform xanthoma is an uncommon benign lesion that affects the skin, presenting as a verruciform (wart-like) appearance. It may also appear polypoid, papillomatous, or sessile.

The histopathology of verruciform xanthoma is distinctive for the presence of foamy histi

Verruciform Xanthoma: Signs and Symptoms

Verruciform xanthoma is a rare benign lesion that can appear on the skin, typically presenting as a single verrucous, papillomatous, or keratotic plaque or nodule. The signs and symptoms of this condition are:

• Single verrucous lesion: Verruciform xanthoma often presents as a solitary, asymptomatic lesion on the skin.
• Yellowish or brownish color: The lesions may have a yellowish or brownish hue due to the accumulation of lipids.
• Painless: These lesions are typically painless and do not cause any discomfort.
• Variable size and location: Verruciform xanthomas can vary in size and location, but they are most commonly found on the oral mucosa.

Other possible locations

While the oral mucosa is the most common site for verruciform xanthoma, these lesions can also be found on other parts of the body, including:

• Genitalia: Verruciform xanthomas have been reported on the scrotum and penis.
• Perioral area: These lesions may also appear in the perioral region.
• Esophagus and aerodigestive tract: In rare cases, verruciform xanthomas can occur in the esophagus and other parts of the aerodigestive tract.

Treatment Options for Verruciform Xanthoma of the Skin

Verruciform xanthoma (VX) is a rare, benign mucocutaneous tumor that can affect the skin. While surgical excision has been considered the criterion standard for treating VX, there are other treatment options available.

• Imiquimod: A study published in the Journal of the American Academy of Dermatology found that imiquimod, an immune response modifier, was effective in treating VX (1). Imiquimod works by stimulating the body's immune system to fight off the tumor.
• Antibacterial wash: There is a solitary report of a patient who responded to treatment with antibacterial wash, which fueled the theory of bacterial pathogenesis (5). However, this is an isolated case and more research is needed to confirm its effectiveness.

It's worth noting that VX lesions have historically been resistant to most treatment modalities. Therefore, treatment options may vary depending on individual cases and patient responses.

Differential Diagnosis of Verruciform Xanthoma

Verruciform xanthoma (VX) is a rare skin condition that can be challenging to diagnose due to its similarity with other skin lesions. The differential diagnosis for VX includes:

• Verruca vulgaris: A common viral infection characterized by small, rough patches on the skin [1][2].
• Condyloma: A type of genital wart caused by human papillomavirus (HPV) [3][4].
• Verrucous carcinoma: A rare and aggressive form of skin cancer that can appear as a verrucous or cauliflower-like growth [5][6].
• Squamous papilloma: A benign tumor that can appear as a small, rough patch on the skin [7][8].
• Granular cell epulis: A rare type of tumor that can occur in the mouth or skin [9].

Key Features to Distinguish VX from Other Lesions

To accurately diagnose VX, it is essential to consider the following key features:

• Large numbers of lipid-laden foamy histiocytes in the lesion [4].
• Presence of koilocytes and coarse hypergranulosis [10].
• Prominent papillomatosis and rete ridges [11].
