Congenital hairy nevus Treatment

Congenital hairy nevus
Two factors influence the treatment of congenital nevi nevomelanocitici: potential for malignant transformation and cosmetic appearance. Surgical excision with reconstruction is the standard therapy. Chemical peels and laser therapy are dermoabraziunea optional adjuvant treatments. All methods of adjuvant therapy were associated with scars. They have not been shown to decrease the malignant potential. If surgical excision is not possible to control is to examine and document the evolution of nevus by high-resolution photography.
Surgical therapy. Attempts to remove large congenital nevi should be initiated early in life. will wait until the child reaches the age of 6 months. Operations before that age increases the risk of interventional and aesthetic. If direct closure was excised after the nevus is not possible reconstruction may include serial excision, excision with skin grafts, skin flaps, tissue expansion, autologous cultured human epithelium, replacement with artificial leather and free tissue transfer.
The goal of treatment is to remove as much as possible nevus and reconstruction of the defect, preserve function and maintaining aesthetics. The presence of large nodular masses i8ndica malignant changes and requires immediate treatment. This table may be a rare neuroectodermal sarcoma. The incidence of melanoma is increased to the scalp, back and thighs first and require removal. Excision starts at age 6-9 months. Assessment of small and medium lesions for prophylactic excision should be started before the age of 12 years. After that age rapidly growing malignant potential.
Adjuvant therapy. Phenol chemical peel technique was used to treat nevi that are too large for excision or are in locations where excision would result in unwanted scars. Multiple sessions are needed and the best results are slightly pigmented lesions, superficial. Dermoabraziunea is useful to increase the depth of peel and shape the surface irregularities. Dermoabraziunea only led to an increased incidence of hypertrophic scars removed without risk of malignancy.
Multiple treatments with ruby laser produced immediate thermal damage to the superficial nests nevocelule and superficial connective tissue remodeling secondary. Successful reduction of pigmentation giant moles of carbon dioxide laser has been reported. The results range from acceptable aesthetic hypertrophic scars.
