Synopsis

Lobular capillary hemangioma, also known as pyogenic granuloma, is a tumor-like, benign reactive, vascular proliferation, essentially an "-oma" of granulation tissue, usually caused by trauma or local irritation. It is not a true neoplastic process. It does not usually suppurate so the term "pyogenic" is a misnomer.

It tends to occur in children and young adults, and 75% occur on the gingiva. However, the labial mucosa, buccal mucosa, and tongue may also be affected. Over time, lobular capillary hemangiomas may sclerose and become more fibrous.

A particular subset occurs in pregnant patients, and this is called "granuloma gravidarum." These occur in the first trimester of pregnancy and grow steady under hormonal influences throughout pregnancy. Post-partum, the lesions tend to become smaller or involute completely. However, many will remain as a smaller, scarred, fibrotic nodule. Patients are aware of an enlarging mass that may bleed easily.

Differential Diagnosis & Pitfalls

  • Peripheral giant cell granuloma also occurs on the gingiva and has a similar appearance.
  • A varix with or without thrombosis may appear similar clinically.
  • Hemangioma is clinically indistinguishable.
  • Hematoma develops very rapidly and resolves within days.
  • Kaposi sarcoma tends to occur in patients with HIV infection or AIDS, or Kaposi sarcoma, non-AIDS.
  • Some abscesses on the gingiva also appear purplish and vascular and develop rapidly. They are always painful and associated with an odontogenic infection.
  • Angina bullosa hemorrhagica is an uncommon condition where blood blisters form very rapidly.
  • Metastatic tumors often involve the gingiva, but these generally occur in older patients. Metastatic renal cell carcinomas in particular are quite vascular and may appear as purplish red nodules.
