Critères d'inclusion/exclusion
Inclusion Criteria:

- Age: =1 years of age

- Large full-thickness defects that require coverage after excision of: Scars, Benign
skin tumors (e.g. neurofibroma), Melanocytic nevus (e.g. giant nevus), Gender
reassignment surgery, Soft tissue defect after trauma, Soft tissue defect after
infection and debridement (e.g necrotizingn fascitis, hidadentitis suppurativa,
purpura fulminans), Flap donorsite (e.g. radial forearm flap)

- Minimal areas requiring coverage (not counting the head and neck area for study
patients in The Netherlands): 1-5 years: minimum 9cm2, 6-16 years: minimum 25cm2,
>16 years: minimum 45cm2

- Signed Informed consent

Exclusion Criteria:

- Patients tested positive for HBV, HCV, syphilis or HIV

- Patients with known underlying or concomitant medical conditions that may interfere
with normal wound healing (e.g. systemic skin and connective tissue diseases, any
kind of congenital defect of metabolism including insulin-dependent diabetes
mellitus, Cushing syndrome or disease, scurvy, chronic hypothyroidism, congenital or
acquired immunosuppressive condition, chronic renal failure, or chronic hepatic
dysfunction (Child-Pugh class B or C), severe malnutrition, or other concomitant
illness which, in the opinion of the Investigator, has the potential to
significantly delay wound healing)

- Severe drug and alcohol abuse

- Pre-existing coagulation disorders as defined by INR outside its normal value, PTT
>ULN and fibrinogen Investigator's discretion

- Patients with known allergies to amphotericin B, gentamicin, penicillin,
streptomycin, or bovine collagen

- Previous enrolment of the patient into the current phase II study

- Participation of the patient in another study with conflicting endpoints within 30
days preceding and during the present study

- Patients expected not to comply with the study protocol (including patients with
severe cognitive dysfunction/impairment and severe psychiatric disorders)

- Enrolment of the Investigator, his/her family members, employees and other dependent
persons (ICTRP)
