What condition is characterized by a red lump forming from the nail bed?

The condition characterized by a red lump forming from the nail bed is pyogenic granuloma. This condition is typically identified by a raised, red, and sometimes bleeding lesion that develops at the site of trauma or irritation, often appearing near the nail. It is essentially an overgrowth of tissue that can occur in response to injury or inflammation.

Pyogenic granulomas are associated with nail trauma, where the nail or the surrounding skin has been damaged, leading to the development of this type of growth. In contrast, paronychia involves infection of the skin around the nail, resulting in localized swelling and redness but not necessarily a distinct lump. Tinea pedis, commonly known as athlete's foot, is a fungal infection affecting the skin on the feet and does not lead to growths or lumps at the nail bed. Onychocryptosis, or ingrown toenails, causes pain and inflammation at the edge of the nail but does not typically result in the formation of a red lump protruding from the nail bed like pyogenic granuloma does.

Understanding the characteristics and causes of these conditions helps differentiate between them, with pyogenic granuloma being specifically related to the formation of a red lump from the nail bed.
