The name "pyogenic granuloma" is misleading, as it is neither pyogenic or a true granuloma. Rather, it is a capillary hemangioma of lobular subtype, which is why such a lesion is prone to bleeding. [5] It is also not truly pyogenic (pus-producing), as the cause is hormonal or traumatic and has no association with infection or pus production.
Neoplasms of the nailbed may often present with paronychia, ingrown nail, onycholysis, pyogenic granuloma, nail-plate dystrophy, longitudinal erythronychia, bleeding, and discolorations.

During the migratory phase of wound healing, granulation tissue is: light red or dark pink, being perfused with new capillary loops or "buds"; soft to the touch; moist; bumpy (granular) in appearance, due to punctate hemorrhages; pulsatile on palpation; painless when ...
The seal between the nail and finger acts as a physical barrier to prevent infection, however hyper-hydration or destruction of the epidermis can impair the barrier, allowing the bacteria to colonise. [medical citation needed] The nail turns green due to the bacteria secreting pigments such as pyocyanin [3] [4] and pyoverdin. [9]
They usually occur in the elderly population (mean age 65.1–66.6 in different studies) as small (<2 centimeters), solitary dome-shaped papules, plaques, or nodules, that are skin-colored, pink, red, white, or blue and range from smooth to wart-like, ulcerative, [4] or pyogenic granuloma-like lesions.

Treatment is with oral antibiotics. [16] Whitlow or felon is a subcutaneous infection of the digital pulp space. The area becomes warm, red, tense, and very painful due to the confinement of the infection, creating pressure in the individual compartments created by the septa of the finger pad.
