Acne fulminans (AF) is a rare and severe form of inflammatory
acne that typically occurs in male adolescents with
acne vulgaris and is characterized by the sudden onset of painful,
bleeding, and ulcerated lesions. It has been described very rarely in association with
hidradenitis suppurativa (HS). Its onset may be induced by drugs, particularly
isotretinoin. We present a case of a 16-year-old patient with HS who developed AF following initiation of
antibiotic therapy with
lymecycline. In the literature, only 2 patients who developed a coexistence of AF and HS have been reported, and there are only 2 other similar cases of AF induced by
doxycycline and
lymecycline. We consider our case to be of particular interest not only because of the very rare concomitant presence of AF and HS but also because AF was induced by
lymecycline, a
drug commonly used to treat both
acne and HS, and described only once as a
drug responsible for AF, so it is an aspect that deserves to be considered by the clinician dealing with similar conditions.
