A 32-year-old male experienced an 8-month-long, therapy-resistant acneiform eruption on his back and buttocks, characterized by inflammatory papules that led to hyperpigmentation and non-inflammatory papules resembling rice grains. Light microscopy revealed small keratin-filled cysts with vellus hairs, leading to a diagnosis of vellus hair cysts. The study suggested that vellus hair cysts should be considered in cases of multiple papules or acneiform eruptions that do not respond to treatment.
