NICOLAU SYNDROME IN A CHILD FOLLOWING IV CLINDAMYCIN INJECTION-DECODING THE PURPLE PUZZLER

Nicolau syndrome is a rare complication of intramuscular injections caused by various drugs that present with intense pain and induration at the injection site. It is characterized by local aseptic skin necrosis and rarely, muscle necrosis on the injection site. It has rarely been reported to occur after intramuscular injections of anti-inammatory drugs, corticosteroids, local anesthetics, penicillin and interferon. Our literature review revealed no cases of Nicolau syndrome following intravenous (IV) clindamycin injections. Herein, we report a case of Nicolau syndrome that occurred after IV clindamycin injection in the left forearm of a 1.5-year child, that was notable because of the uniqueness of the syndrome coupled with the fact that it has not previously been reported after intravenous clindamycin injection.

Nicolau syndrome: a review of case studies

Nicolau syndrome, although it is quite rare, often occurs following intramuscular injections of different medications, especially diclofenac and penicillins. Accordingly, its symptoms usually begin with severe pain during injection, leading to ulceration and necrosis of the local tissue over time. Immediate diagnosis and treatment in the case of this syndrome, are of great importance. There are no established criteria for Nicolau's diagnosis, and preferably, these can be achieved by examining the patient's symptoms and eliminating differential diagnoses. The proposed treatments are primarily symptomatic therapy and measures such as fasciotomy, debridement, and plastic surgery provided in the affected area. The exact cause of this syndrome has not been determined yet. However, since vasospasm, thrombosis, and embolism have been observed in majority of Nicolau syndrome cases, so any intra-arterial/para-arterial injection or any other factor leading to these three conditions could be hypothetically regarded as the cause of this problem. This review aims to provide a comprehensive overview of Nicolau's symptoms, diagnosis, treatment methods, and prevention. It also investigates the association between the incidence of this disease and some factors such as gender, age, injection method, and causative drugs, in order to widen our understanding on this syndrome and help practitioners with a much faster diagnosis method and step-by-step approach to Nicolau syndrome.

Embolia Cutis Medicamentosa (Nicolau Syndrome) Secondary to Intramuscular Fulvestrant Injection: A Case Report

Purpose: A case of embolia cutis medicamentosa (Nicolau syndrome) in a patient receiving monthly intramuscular fulvestrant injections is presented. Summary: An 85-year-old woman receiving monthly fulvestrant injections in the outpatient setting developed a necrotic lesion at the fulvestrant injection site on her right buttock. Her medical history is notable for metastatic breast cancer with bone metastases. Prior to developing the necrotic lesion, the patient was receiving monthly fulvestrant injections for 6 years. Other potential causes such as infection and pressure necrosis were ruled out clinically. After 185 days of wound care involving multiple surgical debridements, topical therapy, and frequent follow-up appointments, the patient’s wound resolved with 100% epithelialization. Nicolau syndrome has been reported with other non-vesicant, injectable medications such as antibiotics and corticosteroids; however, it has not been previously reported with fulvestrant. Conclusion: Nicolau syndrome developed in the right buttock of a patient with metastatic breast cancer following an intramuscular fulvestrant injection. Healthcare practitioners need to be cognizant of this adverse effect with intramuscular injections in order to recognize and refer patients for wound care evaluation early in the evolution of this syndrome. Proper injection technique is recommended to reduce the risk of this idiopathic adverse effect.

Nicolau Syndrome: An Unforeseen Yet Evadable Consequence of Intramuscular Injection

An intramuscular (IM) injection is one of the common routes for administering drugs, commonly analgesics and vaccines. Nicolau syndrome refers to the rapid-onset painful, extensive cutaneous discoloration progressing to necrosis and ulceration, reported after IM injections. This case report highlights a rare but avoidable complication of such injections. An elderly man presented with extensive cutaneous necrosis and discoloration over the buttocks extending to the thigh, within few days after receiving a single shot of IM injection of diclofenac. Management involved wound care, biopsy, and cultures with supportive antibiotics to control superadded infection. After multiple sittings of extensive surgical debridement, the wound showed signs of healing and was ultimately amicable for skin grafting in a month.Health care workers need sensitization toward such a complication that can occur out of a routine procedure like an IM injection. They should follow standard IM injections techniques and take precautions to avoid this mishap, which adds to the patient's morbidity.
