Seborrheic Keratosis
Seborrheic keratosis appears as a raised, often pigmented lesion on the skin. These growths are generally brown, black, or tan, and have a waxy, scaly appearance. Seborrheic keratoses are common among older adults and can be mistaken for other skin conditions, including melanoma.
Their non-invasive nature means treatment is usually not required unless the lesions become bothersome or irritated. Patients should be encouraged to monitor new or changing lesions.
Cherry Angiomas
Cherry angiomas are small, red spots on the skin composed of a cluster of blood vessels. They have a characteristic round shape and can vary in size. Usually found on the trunk or limbs, cherry angiomas increase in number with age. While they are harmless, they can bleed if injured.
Some individuals may opt for removal for cosmetic reasons, but the procedure is typically safe and uncomplicated.
Dermatofibromas
Dermatofibromas are firm, raised nodules that often develop on the legs or arms. Typically brown or tan, these lesions can be quite stable once formed. Dermatofibromas can feel like hard lumps under the skin, with a notable dimple when pinched. Surgical removal is usually done for cosmetic preferences, but they are benign and often do not require treatment.
Keloids
Keloids are thick, raised scars resulting from excessive collagen production during the healing process. They can occur anywhere on the body but are most common on areas like the chest, shoulders, and earlobes. Keloids can vary in color and size and may cause discomfort or itchiness.
Management options include corticosteroid injections or surgical removal, though recurrence is possible. It is vital for individuals predisposed to keloids to discuss options with their dermatologists thoroughly.
Nevi (Moles)
Nevi, or moles, are common skin marks that can appear anywhere on the body. They vary in color from tan to dark brown and can be flat or raised. While most nevi are benign, any changes in size, shape, color, or texture warrant medical evaluation.
Regular skin checks are recommended, particularly for individuals with numerous moles or a family history of skin cancer.
Lipomas
Lipomas are soft, fatty lumps that grow under the skin. They typically feel smooth and movable, ranging from small to several centimeters in size. While they are painless and benign, some people may choose to have them removed if they become uncomfortable or for cosmetic reasons. Lipomas are generally harmless, requiring no treatment.
Pilar Cysts
Pilar cysts, also known as trichilemmal cysts, form around hair follicles and are usually found on the scalp. They appear as round, firm bumps beneath the skin's surface. These cysts are often filled with keratin and can sometimes become inflamed or infected. Removal is simple and can be done in an outpatient setting.
Proper identification and understanding of these benign skin lesions promote more informed discussions between patients and healthcare providers regarding monitoring and treatment. An awareness of their characteristics ensures effective management and minimizes unnecessary anxiety.
