A Case of Alopecia Areata in a Patient with Turner Syndrome

The Authors report a case of alopecia areata totalis in a woman with Turner syndrome.


Introduction
Alopecia areata (AA) is an inflammatory nonscarring form of hair loss, which may involve all the follicular units of the body. It is a common disease, with an incidence of 1-2% [1].
AA may affect people of both sex and all age, even if it is more commonly described in under 30years old patients [2]. Often, it is associated with different inflammatory or autoimmune diseases, like atopic eczema, Hashimoto's thyroiditis, Graves' disease, Celiac disease, vitiligo, psoriasis and others [1].
AA is an autoimmune disease, characterised by a T-cell mediated immune response that targets hair follicles. The clinical manifestations are numerous, ranging from mild lesions, characterised by round or oval patches of hair loss, to the total hair loss, such as in the universal form [3].

Case report
A 28-year-old woman affected by AA, showed up to our Clinic presenting a widespread non-scarring alopecia, which was localised in the scalp and face area. The skin was white-pink in colour and normaltrophic. Black dots and exclamations points were no detected. Only a few vellus-like hairs were present in the midline of the scalp (Fig.1).The patient did not report any subjective symptoms and enjoyed apparent good health.
She reported the appearance of the disease about 26 months ago. Initially, the hair loss was limited to the left temporal side, and consisted in two round little (diameter less than 2 cm), well defined, areas. After few weeks, the hair loss rapidly spread, involving the entire scalp. By five months, the patient also observed the loss of her eyelashes and eyebrows.
The woman told us to be affected by Turner syndrome, Hashimoto's thyroiditis and celiac disease. Her medical treatment consisted of oral levothyroxine _______________________________________________________________________________________________________________________________ 494 http://www.mjms.mk/ http://www.id-press.eu/mjms/ and oestrogen replacement. No other diseases had been reported. She had no familiarity for AA or other autoimmune diseases.
The patient reported previous treatment of alopecia with oral supplements and topical minoxidil 2% 1 ml twice a day for six months. Due to the lack of clinical improvement, she was treated with low dose of topical corticosteroids (hydrocortisone once a day) for three weeks and PUVA therapy, which has been performed twice a week for a total of 20 sessions, both without beneficial results.

During the clinical evaluation, the woman showed characteristic features of Turner syndrome, such as short stature (150 cm), short and squat neck, poor breast development and stubby little hands. She had ears and lower eyelids bigger than normal, enophthalmos, reduced upper lip and a small chin. On the other hand, no other skin lesions were observed. Nails were smaller than normal. A routine laboratory test, including thyroid function tests, were normal. Due to the long duration of the hair disease, we applied intralesional triamcitolone acetonide once a week for two months. Surprisingly, even if localised, we observed a re-growth of the hair. Since hair growth responded to corticosteroids, we switched to oral methylprednisolone 32 mg/die for ten days, followed by 16 mg/die for ten days and, eventually 8 mg/die for another ten days. The clinical response was quite good: the patient showed new hair in the frontal area of the scalp. After one month, we observed the diffuse hair re-growth on the scalp. New eyelashes and eyebrows were also observed (Fig.2).
We decided to reduce progressively the cyclosporine therapy and to stop it. Because of the appearance of new hair loss patches (Fig.3), the patient re-started the treatment with cyclosporine A at a dosage of 200 mg/die. The clinical response was rapid and excellent (Fig.4). During the treatment we constantly evaluated the patient's clinical conditions, monitoring her blood pressure and routine blood test. No side effects or complications had been observed.

Discussion
Turner syndrome (or Ullrich-Turner syndrome) is one of the most frequent chromosomal abnormalities, which results from a sex-chromosomal anomaly characterised by a presence of one normal X chromosome and a missing or structurally abnormal second sex chromosome. It is a rare disease affecting 1:2500 live born girls [4]. The Turner syndrome phenotype includes female gender, short stature, primary ovarian failure and some characteristic physical features (tab.1) [5]. Patients with Turner syndrome have an increased incidence of autoimmune disorders (AID), such as Hashimoto's thyroiditis, Grave's disease, celiac disease, inflammatory bowel disease, and diabetes mellitus [6][7][8].
AA is a chronic inflammatory autoimmune disease, characterised by non-scarring hair loss on the scalp or any hair-bearing area of the body. Clinically it may represent in variable patterns, such as patchy, diffuse, reticulate, linear, or opiates-type. Depending on the severity of hair loss, AA may also be classified as localised (few patches of hair loss), subtotal (diffuse alopecia of the scalp), total (complete loss of scalp hair) or universal (complete loss of body hair) [14]. The course of the disease is highly variable: it may spontaneously regress, be stable or progress to a severe form. Even if numerous treatment options are now available for AA (tab.2), no definitive therapy exists [15,16].
In our case, the patient showed an excellent clinical response to cyclosporine A treatment, initially combined with intralesional corticosteroids.
In conclusion, the authors have presented this case study to record the possible association of AA with Turner syndrome, and therapeutic validity of cyclosporine in stimulating hair growth where other therapies had previously failed.
