Solitary, coarse-elastic, cutaneous or subcutaneous, reddish-livid or skin-coloured node. Mostly benign behaviour with slow growth, but local infiltration and destruction of the surrounding area also possible; very rarely metastasis (sometimes the existence of malignant gemmangiomas is disputed).

Histology
This section has been translated automatically.

Numerous, reticularly arranged, solid, partly channelled capillary rungs of monomorphic angioblasts, reminiscent of granulation tissue. Homogeneous, mostly sparsely developed basic substance without inflammatory cells.

Therapy
This section has been translated automatically.

Because of different dignity, great clinical variability and frequent localization in the face, the treatment depends on the individual case. For small, slow-growing tumours, a simple excision is generally sufficient; for fast-growing tumours suspected of malignancy, it is advisable to maintain a safe distance. In any case histological control!
