Sir,
Nicolau syndrome (NS), also known as embolia cutis medicomentosa and livedo-like dermatitis, is a rare cutaneous adverse reaction at the site of intramuscular, intra-articular or, rarely, subcutaneous injection of particular drugs. NS was first described in patients treated for syphilis with bismuth salts in 1925. [1] It has been reported in the literature with the administration of various other drugs such as penicillin, non-steroidal anti-inflammatory drugs, local anesthetics, vitamin K, triple DTB vaccination, and corticosteroids. [2],[3],[4],[5] Although its pathogenesis is not well understood, the pathophysiology of NS probably involves intra-arterial and/or para-arterial injection and arterial embolism of viscous suspensions of drugs meant for intramuscular, intravenous, or intra-articular injection, followed by acute vasospasm. [2]
We report the case of a 77-year-old female patient who presented a painful ecchymotic plaque on the right buttock. A week ago, she had been given an intramuscular diclofenac injection, and livid discoloration appeared around the injected area. Over the following days, erythema, edema, and painful hemorrhagic blisters developed around the ecchymosis.
On physical examination, a 5 × 4-cm-size, well-defined ecchymotic plaque surrounded by a livedoid, reticular erythematous patch with ruptured blister particles was observed on the right buttock [Figure 1]. General examination was normal, and blood testing revealed a mildly raised erythrocyte sedimentation rate (ESR: 36). Doppler ultrasonographic evaluations for the right lower limb were normal. Histopathologic examination revealed focal necrosis areas of the epidermis, and perivascular eosinophilic infiltrate with extravasation of erythrocytes, no sign of vasculitis was detected.
The differential diagnosis of NS includes cutaneous cholesterol emboli, vasculitis, and cutaneous embolization of cardiac myxoma. Cholesterol emboli usually occurs in the elderly patients with severe atherosclerotic disease and after endovascular manipulation. Left atrial myxomas can cause cutaneous emboli, usually to the acral sites and accompanied by cardiopulmonary symptoms such as chest pain and dyspnea. [6] Our patient did not have any other comorbid conditions such as cardiovascular disease or diabetes. Clinically and histopathologically, the patient was diagnosed as having Nicolau syndrome and treated conservatively with local wound care. Within the following weeks, a necrotic ulcer developed [Figure 2] and finally an atrophic scar remained at the site of injection at three-month follow up.
There is no specific therapy for NS. Treatment depends on the extent of the necrosis, and ranges from topical to surgical. Conservative treatment with debridement, pain control (analgesics), and dressings is the mainstay of therapy, especially for limited cases. Tissue damage may be reversible in the acute phase of NS. Use of vasoactive agents such as subcutaneous heparin and oral pentoxifylline has been recognized as beneficial. Surgical intervention is rarely required. [2] Using of hyperbaric oxygen therapy in selected cases has been reported in the literature. [7]
Although NS is an uncommon cutaneous adverse reaction, the symptoms are dramatic, and this rare complication can cause severe anxiety to the patient. Healthcare personnel should be aware of this condition and take adequate precautions. A sufficiently long needle for an obese patient, the Z-track method of intramuscular injection, injection only after aspiration with a syringe, and an injection in the upper outer quadrant of the gluteal region which has few large blood vessels, can minimize or prevent Nicolau syndrome.
