1st order
Nevus cell nevus
- If there are signs of dysplasia, the changes should be checked regularly and, if necessary, excised (excised) prophylactically
- Benign juvenile melanoma (spindle cell nevus; Spitz tumor) – there is no need for therapy; if necessary, excision if the diagnosis is unclear.
- Dysplastic nevus (atypical nevus, active nevus) – should be excised.
- Halo nevus (Sutton nevus) – there is no need for therapy.
- Nevus pigmentosus et pilosus (giant pigmented nevus) – the changes should be regularly checked, if necessary abraded or excised.
Caveat: 20-30% of malignant melanomas (black skin cancer) arise in the area of a preexisting nevus cell nevus.
Vascular nevi, hemangiomas.
- Granuloma pyogenicum (ICD-10 L98.0; granuloma teleangiectaticum, botryomycoma) – the change should be excised
Epidermal nevi
- Can be excised if they are disturbing
Sebaceous nevi (nevus sebaceus).
- Most often there is a spontaneous regression
- If exophytes occur, the changes should be excised immediately
- Since the development of various tumors (basal cell carcinoma (BZK; basal cell carcinoma), squamous cell carcinoma of the skin, spiradenoma, trichoblastoma) has been described, excision should be sought until younger adulthood
