BCG Induced Cold Abscess as a Complication of Inadvertent Vaccine Injection, a Case Series

We report a four-month-old girl with a right thigh swelling, an eight-month-old girl with a left thigh swelling, and a five-month-old boy with a left thigh swelling with the final diagnosis of BCG-induced cold abscess as a result of erroneous injection of BCG vaccine into the infants’ thigh muscle.

Encapsulated cyst fat necrosis masquerading as cold abscess

Encapsulated fat necrosis is a benign, usually asymptomatic and underreported condition. It is believed to be trauma‐related ischemia and necrosis of fat tissue that gradually detaches from its surroundings. Here we reported a case of encapsulated cyst fat necrosis in a 75 years old female following intramuscular injection, who was clinically diagnosed as cold abscess initially.

Idiopathic Aseptic Facial Granuloma

Pyodermite froide du visage, otherwise known as idiopathic facial aseptic granuloma (IFAG), is a benign lesion exclusively seen in children and presents as a cold abscess on the face.1 We report a case of a 14-year-old male with IFAG who failed initial treatment with oral doxycycline, but responded to treatment with oral 13-cis-retinoic acid, oral trimethoprim-sulfamethoxazole and intralesional triamcinolone injections over a 7 month period.

Florid genital tuberculosis co-existing with adenomyosis and evading diagnosis

When tuberculosis affects genital organs of young females, the disease often remains silent or may present with symptoms which are common to other Gynaecological conditions as well. The diagnosis of genital tuberculosis is challenging and the diagnosis can be missed even with extensive investigations including molecular studies. A case of florid tuberculosis affecting the uterus, cervix, ovaries and tubes, co-existing with adenomyosis of the uterus and the cold abscess masquerading as bilateral ovarian endometriomas is reported.
