Brief Summary
The aging of skin, especially that of the scalp, is a combination of intrinsic and extrinsic aging factors secondary to the chronic sun exposure. For men with an alopecia genetic (= bald men), the solar part, in skin aging process, is major. The helio-dermal scalp is frequently the site of cancers mainly after 65 years. Objectives are to identify specific biomarkers involved in the photo-aging of the alopecic scalp

Study Arms (1)
Patients who will benefit from the removal of a scalp tumour
EXPERIMENTALPatients who will benefit from the removal of a scalp tumour in the alopecic zone will be recruited in the dermatology department of the St-Etienne University Hospital. They will have biopsy, blood sample, examination of the scalp, questionnaire on sun exposure, Norwood scale, scinexa score, questionnaire of clinicals signs and questionnaire of the history of the hair loss.
Interventions
Biopsy 4 to 5 mm from the distal part of the tips of the excision pieces. Three biopsies of 3 mm, made with punch, occipital hair zone (ZT) A completely painless sample, using a swab (soaked with a buffer solution) on the scalp of the ZH and ZT zone.
Blood sample will be collected for performed for HIV serology, B and C hepatitis.
Questionnaire on sun exposure will be completed by patients.
A complete examination of the scalp will be completed by dermatologist.
Norwood scale measure the evolution of baldness. It will be completed by dermatologist.
Questionnaire of clinicals signs will be completed by dermatologist and patient.
It's a assessment score of skin aging. It will be completed by dermatologist.
Questionnaire of the history of the hair loss will be completed by dermatologist and patient.
Eligibility Criteria
You may qualify if:
- Requiring excision of an alopecic scalp lesion
- from consent signed
- Patient affiliated or entitled to a social security.
You may not qualify if:
- scalp infection
- inflammatory disease of the scalp
- genetic disease with even partial expression of the scalp
- medical treatment of scalp less than 3 weeks old
- antecedent radiotherapy of the cephalic extremity
- prior surgery of the scalp with regard to the area sampled
- Application of hair implants, or any other surgical or medical procedures of the scalp
- Washing of the scalp or application of a cosmetic product for less than 48 hours
- Artificial hair coloring.
- any contraindication to surgical excision
