What is a bump with black dot?

There are many potential causes for a bump with a black dot, including:

* A sebaceous hyperplasia. These are benign, non-cancerous growths that are caused by overactive sebaceous glands, which produce oil. They are often small, round, and flesh-colored, with a black dot in the center. Sebaceous hyperplasia can occur anywhere on the body, but they are most common on the face, chest, and back.

* A cherry angioma. These are benign, non-cancerous growths that are caused by a cluster of blood vessels. They are often small, round, and red, with a black dot in the center. Cherry angiomas can occur anywhere on the body, but they are most common on the trunk, arms, and legs.

* A melanocytic nevus. These are benign, non-cancerous growths that are caused by an overgrowth of melanocytes, which are cells that produce pigment. They are often small, round, and brown, with a black dot in the center. Melanocytic nevi can occur anywhere on the body, but they are most common on the face, neck, and arms.

* A skin cancer. Some types of skin cancer can appear as bumps with black dots, including melanoma, squamous cell carcinoma, and basal cell carcinoma. These types of skin cancer are rare, but they can be serious if they are not treated promptly.

If you are concerned about a bump with a black dot on your skin, it is important to see a dermatologist for evaluation. The dermatologist can determine the cause of the bump and recommend treatment if necessary.
