Case report details a sarcoidal granuloma in a patient after microneedling, highlighting risks and implications.
Microneedling is a popular dermatologic procedure, but complications such as granulomatous reactions may occur. We report a case of a 51-year-old Filipino female who developed a sarcoidal-type granuloma over a scarred eyebrow area 2 weeks after unsupervised microneedling using a home device. Histopathology confirmed sarcoidal-type granulomas. Systemic sarcoidosis was ruled out. The lesion responded well to two sessions of intralesional triamcinolone acetonide, with no recurrence after 1 year. This case highlights the potential for sarcoidal granulomatous reactions following microneedling, possibly due to trauma, nickel exposure, or immune dysregulation in scar tissue. Awareness, proper technique, and professional supervision are essential, particularly in patients with prior cutaneous injury or sensitivity.
