Seborrheic dermatitis treatment with stellate ganglion block

disorder characterized by hyperkeratosis, acanthosis, accentuated rete ridges, focal spongiosis, and parakeratosis. It is usually caused by increased sebaceous gland activity, and manifests itself through the apparition of ill-defined eryhematous patches accompanied by fine scaling in areas of high sebum secretion, including the scalp, face, eyebrows, nasal alar creases, melolabial folds, ears, central chest, and genital region. Although the fundamental cause of seborrheic dermatitis has not yet been established, many etiologic factors are believed to play a role in the development of the disorder. In particular, increased sebaceous gland secretions, metabolic changes in the cutaneous microflora, and host immune function changes are considered some of the major causes [1]. According to Uchida et al. [2], stellate ganglion block (SGB) is effective in the treatment of skin disorders of the head and neck. According to the authors, this treatment mechanism maintains the homeostasis of hormones by improving the blood flow in the brain. There has been a report of successful treatment of acne vulgaris — which has a similar etiology to seborrheic dermatitis — with SGB [3]. Therefore, we predicted that SGB would also be effective in the treatment of seborrheic dermatitis. Indeed, repeated SGB trials on a patient who had previously undergone unsuccessful dermatologic treatments were effective. This was the first case of seborrheic dermatitis treatment with SGB.
