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.
Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps. Its histological appearance is characterized by proliferation of fibroblasts and thin-walled, delicate capillaries ( angiogenesis ), and infiltrated inflammatory cells in a loose extracellular matrix.

Glomus tumors are usually solitary and small lesions. The vast majority are found in the hand, wrist, foot, and under the fingernails. [3] They are often painful, and the pain is reproduced when the lesion is placed in cold water - a history of sensitivity to cold weather is also common. [6] Multiple tumors are less likely to be painful.
Surgical excision is the primary discretionary, elective treatment option for ganglion cysts. Alternatively, a hypodermic needle may be used to drain the fluid from the cyst (via aspiration). [ 26 ] The recurrence rate is about 50% following aspiration of a ganglion cyst.
Nodules in skin include dermatofibroma [5] and pyogenic granuloma. [6] Nodules may form on tendons and muscles in response to injury, [7] and are frequently found on vocal cords. [8] They may occur in organs such as the lung, [9] or thyroid, [10] or be a sign in other medical conditions such as rheumatoid arthritis. [11]
Neoplasms of the nailbed may often present with paronychia, ingrown nail, onycholysis, pyogenic granuloma, nail-plate dystrophy, longitudinal erythronychia, bleeding, and discolorations. [ 1 ] : 792 There are various benign and malignant neoplasms that may occur in or overlying the nail matrix and in the nailbed, and symptoms may include pain ...
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.
