Study Notes
Necrotic Tissues
- Necrotic tissues must be removed along with the punctum and the cyst, and then allowed to return to their natural state before removal.
Dermoid Cyst
- Differentiation between dermoid cyst and lipoma is based on site.
- Sequestration can occur in dermoid cysts, especially in the ovary, testis, and posterior mediastinum.
- Other common sites for dermoid cysts include preauricular and postauricular areas.
- Teratomatous dermoid cysts can occur in the ovary, testis, and posterior mediastinum.
Haemangioma
- Surgical excision is necessary for haemangiomas in certain cases.
- Haemangiomas can occur in the eye and require surgical excision.
- Large haemangiomas can cause hyperdynamic circulation and lead to congestive heart failure (CHF).
- Haemangiomas in the liver can rupture and cause hemorrhage, especially after trauma.
- Infected haemangiomas require surgical excision.
- Haemangiomas in exposed areas are prone to trauma.
Lipoma
- Lipomas can cause skin dimpling due to fibrous tissue septa.
- Large lipomas in the neck and back may be liposarcomas.
- Other types of lipomas include parosteal and intrarticular lipomas.
- Extradural lipomas can cause paraplegia or incontinence.
