Seboacanthoma

Seboacanthoma is a benign skin tumor that originates from the sebaceous gland. It is a rare condition and is often mistaken for other skin conditions due to its similar appearance.

Overview

Seboacanthoma is a type of acanthoma, a group of skin conditions characterized by the abnormal growth of the epidermis, the outermost layer of the skin. It is specifically associated with the sebaceous glands, which are small oil-producing glands present in the skin.

Symptoms

The primary symptom of seboacanthoma is the presence of a small, firm, skin-colored or yellowish nodule on the skin. The nodule may be solitary or multiple and is usually less than 1 cm in diameter. It is most commonly found on the face, particularly on the eyelids, but can also occur on the trunk, neck, and extremities.

Causes

The exact cause of seboacanthoma is unknown. However, it is believed to be associated with aging and sun exposure. It is more common in older adults and in individuals with fair skin.

Diagnosis

Diagnosis of seboacanthoma is typically made based on the clinical appearance of the skin lesion. A biopsy may be performed to confirm the diagnosis and to rule out other skin conditions, such as basal cell carcinoma or squamous cell carcinoma.

Treatment

Treatment for seboacanthoma is usually not necessary as the condition is benign and does not cause any symptoms. However, if the skin lesion is bothersome or cosmetically undesirable, it can be removed through surgical excision or cryotherapy.
