Verruciform xanthoma
Verruciform Xanthoma
Verruciform xanthoma (pronunciation: ve-ru-ci-form zan-tho-ma) is a rare, benign skin lesion typically found in the oral cavity, but can occur on any part of the skin.
Etymology
The term 'verruciform' is derived from Latin, where 'verruca' means wart and 'form' means shape. 'Xanthoma' is derived from the Greek words 'xanthos' meaning yellow and 'oma' meaning tumor. Thus, 'verruciform xanthoma' refers to a wart-like yellow tumor.
Description
Verruciform xanthoma is characterized by the presence of foamy histiocytes (a type of white blood cell) within the epidermis. It is often associated with mucosal surfaces and is most commonly found in the oral cavity, particularly on the gingiva (gums). However, it can also occur on the skin, especially in areas of chronic irritation or inflammation.
Symptoms
The lesion is usually asymptomatic and presents as a solitary, well-demarcated, yellowish or pinkish nodule or plaque with a verrucous or papillomatous surface. The size can vary from a few millimeters to several centimeters.
Diagnosis
Diagnosis of verruciform xanthoma is primarily based on histopathological examination. The characteristic histological feature is the presence of large numbers of foam cells in the upper dermis.
Treatment
Treatment typically involves surgical excision of the lesion. The prognosis is excellent, with a low rate of recurrence after surgical removal.
