A benign tumour containing tissue from any organ.
Benign tumor consisting of an overgrowth of mature cells that normally occur in the affected part, but often with one element or type predominating.
A benign (not cancerous) tumorlike growth consisting of normal mature cells in abnormal numbers or distribution. For example, a lung hamartoma contains normal pulmonary tissue, such as smooth muscle and collagen, growing in a disorganized manner. Because hamartomas generally cause no harm and because of the risks involved, surgical removal is generally not done.
An overgrowth of mature tissue in which the elements show disordered arrangement and proportion in comparison to normal. The overgrowth is benign but malignancy may occur in any of the constituent tissue elements.
These are benign tumours, usually in the lung, containing normal components of pulmonary tissue such as smooth muscle and connective tissue.
A tumor resulting from new growth of normal tissues. The cells grow spontaneously, reach maturity, and then do not reproduce. Thus, the growth is self-limiting and benign.
A hamartoma is a benign growth that looks like a tumor and is made up of an excessive growth of tissues typically found in the impacted part of the body. While hamartomas are commonly found in the skin, with haemangioma being the most typical, they can also occur in the lungs, heart, or kidneys.
A cluster of cells forming a nodule, originating from developmental errors in the embryo. Although not true tumors, these formations, known as hamartomas, are similar to vascular birthmarks like nevi. While generally non-cancerous, some may eventually undergo changes that make them neoplastic.
