Sarcoidosis is a multisystemic disease of unknown etiology characterized by the presence of epithelioid granulomas without caseous necrosis in the organs involved. Sarcoidosis cutaneous lesions can be severe. There is no recommendation for the treatment of cutaneous sarcoidosis. A recent study highlights the potential efficacy of mTOR inhibitors in the treatment of sarcoidosis granulomas. The hypothesis is that sirolimus could be effective for sarcoidosis treatment, especially for cutaneous lesions. The main objective of this study is to evaluate sirolimus efficacy on cutaneous sarcoidosis of the face. The main evaluation criteria is the percentage of patients with a significant clinical response (relative decrease in "facial SASI" ≥ 25%) at week 16 of treatment.

Sirolimus, tablets 2 mg/day with dose adjustment of 1 to 3 mg/day for residual concentrations between 4 and 10 ng/mL 1 dose daily for 16 weeks
Percentage of patients with a significant clinical response
Significant clinical response will be defined as a relative decrease in "facial SASI" ≥ 25% compared to baseline. Facial SASI score evaluates 4 features for each of 4 facial quadrants and the nose: erythema, induration, and desquamation, each ranging from 0 (none) to 4 (very severe), and an area score ranging from 0 (0%) to 6 (90-100%). The maximal range of modified Facial SASI scores is 0 to 72.
Time frame: at week 16
Percentage of patients with a good clinical response
A good clinical response will be defined as a relative decrease of "facial SASI" ≥ 50%. Facial SASI score evaluates 4 features for each of 4 facial quadrants and the nose: erythema, induration, and desquamation, each ranging from 0 (none) to 4 (very severe), and an area score ranging from 0 (0%) to 6 (90-100%). The maximal range of modified Facial SASI scores is 0 to 72.
Time frame: at week 16
Percentage of patients with complete clinical response
Complete clinical response will be defined as "facial SASI" = 0. Facial SASI score evaluates 4 features for each of 4 facial quadrants and the nose: erythema, induration, and desquamation, each ranging from 0 (none) to 4 (very severe), and an area score ranging from 0 (0%) to 6 (90-100%). The maximal range of modified Facial SASI scores is 0 to 72.
Time frame: at week 16
Percentage of patients with an improvement of their quality of dermatological life
An improvement will be defined as a decrease of Dermatology Life Quality Index (DLQI) questionnaire\> 25%. DLQI goes from 0 to 30. A lower score indicated a good quality of Life, and a higher score a worse quality of life.
Time frame: at week 16
Comparison of face facial photographs with good brightness compared to baseline
Qualitative clinical aspects of skin sarcoidosis lesions will be compared between baseline and Week 16, as an illustrative proof in addition to quantitative skin score assessment (Facial SASI)
