In addition to well-accepted indications, etretinate has a beneficial effect in a variety of other dermatoses such as the hyperkeratotic eczema of the palms and soles, prurigo nodularis, and other nonpsoriatic, sterile, pustular eruptions. Due to its influence on dermal inflammatory processes and immunomodulation of the tissue response, etretinate is effective in cutaneous
lupus erythematosus
, certain bullous disorders like pemphigus herpetiformis, the persistent variant of Grover's disease, dermatitis herpetiformis, and bullous pemphigoid.
Isotretinoin
is reported to be effective in cutaneous sarcoidosis, disseminated granuloma annulare, systemic sclerosis and tumors of the cutaneous appendages. New synthetic retinoids have been developed. Etretin, the main metabolite of etretinate, was shown to be effective and to have a short elimination half-life of approximately equal to 50 h. Arotinoid ethyl ester and arotinoid-free carboxylic acid are effective in minimal doses 500-fold lower than etretinate. Arotinoid ethyl ester was shown not to increase serum lipids. Arotinoid ethyl sulfone is the first retinoid without bone toxicity in animal experiments. Motretinide is the ethylamide of tretinoin and is reported to be effective in the local treatment of acne. Some of the new polyaromatic retinoids appear to have sebosuppressive, antikeratinizing and/or anti--inflammatory effects via topical application.

Eight of ten patients with chronic or subacute cutaneous
lupus erythematosus
completed 16 weeks of oral isotretinoin therapy (80 mg/day). All eight patients noted an excellent clinical response without significant side effects. (Two patients did not return to initial two-week follow-up.) Peripheral blood B- and T-cell counts were unaffected by therapy. Therapy was associated with resolution of routine histopathologic abnormalities, conversion of abnormal lesional direct immunofluorescence microscopy to normal, normalization of the epidermis on electron microscopy, and reduction of all T cells near the dermoepidermal junction without change in ratio of T-helper/inducer cells to T-suppressor/cytotoxic cells.
Isotretinoin
is a clinically effective short-term therapy for chronic or possibly for subacute cutaneous
lupus erythematosus
. The primary mechanism of action remains unestablished.

Systemic isotretinoin has been used to treat severe acne vulgaris for 20 years. However, isotretinoin also represents a potentially useful choice of drugs in many dermatologic diseases other than acne vulgaris. Diseases such as psoriasis, pityriasis rubra pilaris, condylomata acuminata, skin cancers, rosacea, hidradenitis suppurativa, granuloma annulare,
lupus erythematosus
and lichen planus have been shown to respond to the immunomodulatory, anti-inflammatory and antitumor activities of the drug.
Isotretinoin
also helps prevent skin cancers such as basal cell carcinoma or squamous cell carcinoma. A combination of systemic isotretinoin and interferon-alpha-2a may provide a more potent effect than isotretinoin alone in the prevention and treatment of skin cancers.Systemic isotretinoin may be considered as an alternative drug in some dermatologic diseases unresponsive to conventional treatment modalities. However, randomized clinical trials aimed at determining the role of systemic isotretinoin therapy in dermatologic diseases other than acne vulgaris are required.
