Lipoma is the most common benign soft tissue tumour with most located in the superficial subcutaneous plane. However, some are located in the deeper plane. Location in the head and neck regions are less common compared to the other part of the body. Deep seated lipomas are either inter-muscular or intramuscular. We present a case of a simple subcutaneous neck lipoma in a 60-year-old Malay man which turned out to be an intramuscular sternocleidomastoid lipoma.

The fibrosis involved in gluteus maximus causing limitation of flexion and adduction of the hip has become a recognized clinical entity since the first report by Fernandez de Valderrma in 1969. Its most constant and characteristic histologic feature was substitution of the fibrous tissue in the definitive etiology was unknown but presumed to be multiple intramuscular injections. Authors present three cases of the fibrosis involving gluteus maximus. In two cases Z-lengthening was performed on the thickened fibrous bands with good results.

Dislocation of the shoulder after intramuscular injection antibiotic(s) is rare and this conditon was limit described in literature. Our purposes were: (1) determining the clinical symptoms, X-ray and CT findings; and (2) determining the indications and the surgical technique and evaluation of the surgical result. Material and methods: 62 children (29 females, 33 males) aged from 4 to 16 years were included. Clinical and X- ray findings were analysed for anterosuperior subluxation or dislocation of humeral head. The patients were operated to release of origin or insretion of the mild Deltoid muscle or Z plasty of this one. Surgical procedures provided good result in 75.3 percent, fair in 24.7 percent and there were no infection or neuromuscular complication in these cases. Conclusions: This condition always resulted from repeated Deltoid intramuscular injection. The surgical treatment with resection of fibrous portions constantly gives relief of symptoms and provides good function.

Esfenvalerate is a kind of commonly used highly effective pyrethroid insecticide. It is common for people who are poisoned by contact or misuse, but rarely reported for people who are poisoned by intramuscular injection. This paper reports a case of intramuscular injection of esfenvalerate in the Department of Infection, West China Hospital of Sichuan University in November 2021. The patient was intramuscularly injected with about 20 ml of esfenvalerate, inducing the sense of swelling and tingling, degeneration and necrosis of striated muscle tissue at the injection site, also liver function damage and other manifestations. The patient was discharged from hospital after rehydration, accelerating poison metabolism, anti-infection, liver protection and local puncture.

BACKGROUND: Although used for obtund pain, bupivacaine may itself initially produce pain on injection. This study was designed to evaluate the effect of diluting bupivacaine with normal saline, lactated Ringer's solution, 5% dextrous in water and distilled water on perception of pain associated with intramuscular injection. METHODS: Twenty-five healthy volunteers were involved in this study. Each subject received 4 injections in random order: 0.25% bupivacaine in normal saline, lactated Ringer's solution, 5% dextrous in water and distilled water. Both upper trapezius muscles were used for the intramuscular injection site. Needle size (25-gauge), injection depth (1.5-2 cm), injection volume (2.5 ml), administration speed (0.5 ml/sec), and temperature (room) were controlled for each of the four injections. The intensity of pain was rated on a 0 to 10 visual analogue scale (VAS) score at the point of needle insertion and injecting solutions. RESULTS: There was no statistical difference among each solution in VAS score. However, the VAS scores of drug administration were higher than those of needle insertion in all diluting solutions (P<0.05). CONCLUSIONS: There was no difference in the intensity of pain of an intramuscular injection of bupivacaine between four different kinds of solutions. However, it might be suggested that more effort and investigation will be needed to reduce pain with an intramuscular injection.

Nicolau syndrome or embolia cutis medicamentosa is an acute necrotic condition of skin that follows intramuscular injection of drugs. A 36-year-old man developed a painful, purpuric and erythematous patch on his left buttock following an intramuscular injection of diclofenac sodium. Histologically, the patch lesion displayed epidermal necrosis, dermal degeneration, and vascular thrombosis. We report a rare case of Nicolau syndrome following intramuscular injection of diclofenac sodium. In our case, the patient was successfully treated by surgical excision with primary closure.

Nicolau syndrome is a rare adverse reaction at the site of an intramuscular injection, and is characterized by severe pain immediately after the injection and rapid development of distinct skin lesions. As this syndrome is rare, it may be overlooked at the early clinical phase and subsequently, clinical outcomes may be worse due to delay in treatment. We report on a female who developed Nicolau syndrome following intramuscular diclofenac injection, which required surgical reconstruction. Understanding the characteristics of Nicolau syndrome and careful surveillance for relevant clinical features may help physicians to more quickly diagnose and treat this condition.

Nicolau syndrome is a rare adverse reaction of the skin at the site of intramuscular drug injection, and has largely unidentified pathogenesis. It consists of the development of an acute, severe pain and a localized erythematous rash during intramuscular injection leading to cutaneous, subcutaneous and even muscular necrosis. We report a case of a 55-year-old woman who presented with a painful skin necrosis in her buttocks following an intramuscular diclofenac-beta-dimethyl-aminoethanol injection.
