Massive exophytic abscesses and fibrotic masses of the chin: A variant of the follicular occlusion triad

We present a patient with an extensive cluster of exophytic nodules that developed on his chin. These nodules consisted of abscesses and fibrotic areas. Lesion morphology, histology, and microbiology support a follicular occlusion triad entity. However, the distribution is striking and does not fit the entities described in the triad. We present the case to show that follicular occlusion was the inciting factor in our patient's eruption and to broaden our concept of clinical manifestations that can arise from this pathologic process.
