ARTICLE
A 42-year-old Caucasian woman came to our Department because of the rapid
onset of multiple nodules on her face. The patient stated that the lesions
started one year previously and rapidly grew to their present size. Her
past medical history was significant for several episodes of renal calculi,
hypertension, type II diabetes mellitus, arthrosis and depression. She
was following a medical treatment quite anarchically based on: diclofenac,
atenolol, hydrochlorothiazide, melitracen hydrochloride-flupenthixol dihydrochloride
(Deanxit®), amineptine, lorazepam, glibenclamide and metformin.
Clinical examination revealed the presence of
multiple nodular lesions on her face (Fig.
1) that deformed her anatomy in some areas (Fig.
2). A closer examination revealed also the presence of comedones,
non-inflammatory papules, cystic lesions and confluent masses.
Macronodular iatrogenic
acne due to amineptine
In this case, a biopsy was unnecessary since the clinical examination
and a detailed history lead us to a diagnosis. The patient admitted that
she was taking amineptine at will, varying from 2 to 5 pills a day. We
wrote a letter to her psychiatrist suggesting that amineptine be stopped,
and started the patient on oral isotretinoin (1 mg/kg).
Discussion
The first acneiform reaction to amineptine (Survector®)
was seen in our department in 1989 [1]. Several other cases have been
published [2-11].
Cutaneous adverse reactions to antidepressant
drugs are rare and include: phototoxicity (imipramine and proptriptyline),
urticaria-like rashes, hyperhidrosis, and Lyell syndrome (amoxapine).
One case of acne due to maprotiline has been also described [12].
The acneic reaction to amineptine can appear in depressed patients who
take therapeutic doses ranging from 2 to 4 pills a day. This tricyclic
antidepressant drug is extremely effective because of its rapid euphoric
(amphetamine-like) effect, leading in some cases to addiction. The intensity
of the disease seems to correlate with the dose. Most patients develop
acne 6 to 18 months after starting amineptine.
As in other cases of iatrogenic acne, amineptine acne typically appears
late in life and may regress when the treatment is discontinued. The main
characteristics of the lesions are that they are exclusively comedonic
and cystic with a total absence of inflammation. The treatment suggested
in the literature is oral isotretinoin but surgical excision of larger
lesions may be the treatment of choice.
