    Abstract

    Although the exact incidence of textile contact dermatitis is

    unknown, recent studies demonstrate that contact dermatitis producedby allergic or irritant reactions to clothing not only is more frequent

    than previously thought but also increasing. The clinical features of

    contact dermatitis (CD) caused by clothing may resemble common

    allergic contact dermatitis or may have atypical presentations. We

    report on several cases of clothing-induced contact dermatitis with

    atypical clinical presentations.

    The exact incidence of textile contact dermatitis is unknown, but

    recent studies demonstrate that contact dermatitis produced by

    allergic or irritant reactions to clothing is more frequent than

    previously thought. [1,2,3,4] It also has been shown that the

    frequency of textile-dye allergy is increasing.[5,6]

    The clinical features of contact dermatitis (CD) caused by

    clothing may resemble common allergic contact dermatitis or may

    have atypical presentations. The diagnosis of contact dermatitiscaused by clothing may be difficult in some cases because of the

    wide spectrum of clinical presentations, including unusual clinical

    patterns and atypical localization. In this report, we discuss severalcases of clothing-induced contact dermatitis that presented atypically.

    Methods

    All patients were patch tested with the standard series (TRUE

    Tests), textile color and finish series (TCFS), and clothing extracts.

    The TCFS was obtained from Chemotechnique Diagnostics (Malmo,

    Sweden) and included 32 allergens (13 disperse dyes, 8 reactive dyes,

    3 acid dyes, 1 basic dye, 1 direct dye and 6 textile-formaldehyderesins). The allergens, applied on square chambers with micropore

    tape, were placed on unaffected skin of the upper back, removed at

    day 2 and read at days 2, 3, and 7, according to standard patch test

    procedure.[7] Some of the patients were patch tested with extracts of

    the suspected garments. The extract procedure was as follows: 2 cm

    of the cloth was immersed separately in 5 cc of water, ethanol 70

    percent, and acetone for 30 minutes. The clothing was removed andthe extracts with the water and alcoholic solutions were prepared for

    patch testing. Acetone extract (1 cc) was diluted with 3 cc of water,

    and this solution was used for patch testing. A 1 cm piece of clothing,

    having been immersed in water, was also applied, unaltered, for patch

    testing.

    Case presentations

    Erythema multiforme-like textile CD

    Case 1.A 44-year-old, atopic woman presented with a pruritic,

    widespread eruption on her abdomen and inner thighs, which

    disseminated to the lower back and upper extremities. The present

    eruption developed 1 week after the patient wore a new blue suit of

    synthetic material. A large area of erythema was seen on the patient's

    abdomen. This area was in direct contact with the trousers (Fig. 1).

    Erythematous macules and urticarial papules and plaques, some ofthem target-like, were observed on the inner thighs, shins, and upper

    extremities, in a manner resembling erythema multiforme (Fig. 2).

    A lesional biopsy revealed mild focal spongiosis of the

    epidermis and a mild perivascular infiltrate composed of lymphocytes

    and eosinophils. The eosinophils were also conspicuous in the

    interstitial areas a (Figs. 3, 4). Patch testing results are shown in

    Table 1 and Figure 5. The erythema-multiforme-like eruption

    resolved within 14 days after exposure to the blue synthetic suit was

    discontinued.

    In the past she had developed a similar eruption at and near the

    sites of metallic suture clips on her lower abdomen, after Caesarean

    section. Patch testing then demonstrated hypersensitivity (+2) to

    nickel sulfate. The metal clips were reported by the manufacturer as

    containing nickel. She was diagnosed as having erythema-

    multiforme-like CD related to nickel allergy.

    Case 2.A 32-year-old healthy woman presented with an

    eruption of pruritic, erythematous macules and urticarial papules on

    her shins, resembling erythema multiforme lesions (Fig. 6). An

    allergic reaction to the beige synthetic stockings worn by the patient

    was suspected. Patch test results, as shown in Table 1, confirmed this

    relationship.

    Purpuric textile CD

    Figure 7 Figure 8

    Case 3.A 64-year-old healthy man presented with purpuric

    papules and plaques affecting his lower extremities (Fig. 7) and arms.The lesions appeared in the winter, 1 month after he began wearing a

    dark blue synthetic sportswear while playing tennis.

    A lesional biopsy demonstrated spongiosis of the epidermis with

    areas of acanthosis. The inflammatory infiltrate was mainly

    perivascular and consisted of lymphocytes, eosinophils, and

    extravasated erythrocytes (Fig. 8). Some erythrocytes were observed

    in the epidermis.

    Patch testing (Table 1) revealed a purpuric patch at the site of

    the tested allergen, Disperse Blue 124. A biopsy at this test siterevealed spongiosis, exocytosis, and a perivascular, lymphocytic

    infiltrate. Extravasated erythrocytes were seen in the dermis and the

    epidermis. Complete involution, with no recurrence of the lesions,

    occurred 40 days after discontinuing the use of the blue suit and other

    darkly colored garments and provided further evidence for the

    etiological role of hypersensitivity to textile dyes in the development

    of this patient's purpuric dermatitis.

    Case 4.A 58-year-old man

    was evaluated because of a pruritic,

    papular rash that appeared 3 weeks

    after he started wearing new shirts

    bought in Turkey. Multiple,

    erythematous and livid papules were

    seen on his lower back and flanks.

    The lesions had a linear distributionat the waistband (Figs. 9, 10). Figure 11

    Patch testing results are shown in Table 1 and Figure 11.

    Histopathological investigation of a papular lesion demonstrated

    spongiosis and acanthosis of the epidermis. A mixed inflammatory

    infiltrate consisting of lymphocytes, eosinophils, and multiple

    erythrocytes were seen both perivascularly and in the interstitial area.

    Similar clinical and histological findings were observed from a patch-test site positive for urea-formaldehyde. The lesions involuted

    completely and did not reappear after the patient stopped wearing the

    newly purchased shirts.

    Pigmented textile CD

    Case 5.A 23-year-old

    healthy female presented withpruritic, hyperpigmented patches on

    her neck, chest (Fig. 12) and arms,

    which appeared some months after

    she began to wear synthetic, dark-

    colored, turtle-neck blouses.

    Examination revealed

    hyperpigmented patches at the same

    areas. Patch testing (Table 1)

    demonstrated a hypersensitivity reaction to Disperse Blue 106,

    Disperse Blue 124, a piece of a blouse, and an acetone extract of the

    garment. The lesions began to fade 1 year after exposure to dark

    synthetic garments was stopped.

    Case 6.A 56-year-old, atopic

    woman presented because of severe

    generalized pruritus. Areas of

    excoriation could be seen on her

    trunk and extremities (Fig. 13, 14).

    A lesional biopsy demonstrated mildspongiosis and a mild perivascular

    lymphocytic infiltrate. Multiple

    eosinophils were seen in the

    perivascular and interstitial area. A

    diagnosis of atopic dermatitis was considered. Medications

    (conjugated estrogens and atrovastatin) were withdrawn in order to

    rule out drug-induced pruritus. No improvement resulted. The

    patient's pruritus worsened despite treatment with antihistamines.

    Systemic steroids produced clinical improvement but relapse

    occurred after withdrawal of therapy. A thorough workup for

    generalized pruritus, including liver, renal, and thyroid function tests,bacteriology, and chest X-ray, was performed but rendered no

    relevant information. Positive patch-test results to Disperse Blue 106,

    85, and 124 persisted for 3 weeks( Fig. 15). The pruritus appeared to

    be related to a hypersensitivity reaction to textile dyes and resins, and

    so the patient began to wear only white and beige cotton garments.

    By 1 months, the pruritus was diminished and was completely

    resolved in 2 months.

    Atopic dermatitis-like textile CD

    Case 7.A 10-year-old boy with suspected atopic dermatitis

    was referred to our clinic for investigation of environmental contact

    allergens. He had been suffering from pruritus on his palms, wrists,

    and shins for several months. The boy had participated in a soccer

    team for 3 years as a goal keeper. He had been wearing special gloves

    and shin shields consisting of an external hard plastic cover, rubber

    padding, and a dark textile lining on the inside, that came in contact

    with the skin. Lichenification on the wrists, shins, and popliteal areas

    was observed.

    Patch testing with standard textile and rubber additive series, as

    well as extracts and pieces of the rubber part of the gloves and shields

    and parts of the textile lining was carried out. Hypersensitivity

    reactions occurred at the sites of the alcohol extracts of the textile and

    pieces of the black textile used in the lining. No hypersensitivity

    reactions were observed to any of the standard textile and colorsfinish

    allergens. The lesions resolved after changing the shield to another

    brand.

    Discussion

    Chronic subacute and acute dermatitis are the most frequent

    presentations of textile contact dermatitis according to previous

    studies.[2,3,4,6] Erythematous patches with or without finedesquamation are a common form of textile dermatitis. Usually these

    lesions develop at sites where the garments fit tightly, such as inner

    and posterior thighs, popliteal fossae, buttocks, waistband area, and

    anterior and posterior axillary folds, sparing the vault (Figs. 16, 17).

    Textile dermatitis can also assume other clinical appearances that are

    atypical and thus delay the correct diagnosis of CD produced by

    clothing.

    Figure 16 Figure 17

    Erythema-multiforme-like lesions can be an atypical

    manifestation of hypersensitivity to disperse dyes, as reported in theliterature and observed in two of our patients.[8,9,10,11] Erythema-

    multiforme-like CD related to hypersensitivity to the azo dye,

    Disperse blue 124, was reported even in a child.[12] In our cases, the

    erythema-multiforme-like CD lacked the typical target lesion and the

    histopathological findings resembled those of contact dermatitis,

    including the admixture of multiple eosinophils in the inflammatory

    infiltrate. In the first case, erythema-multiforme-like CD was

    provoked by exposure to two different types of allergens, nickel and

    azo dyes. This finding shows that erythema-multiforme-like reactions

    are not allergen specific but rather represent a pattern of response to

    delayed-type hypersensitivity to topical agents.

    Purpuric CD related to hypersensitivity to textile dyes and resins

    has been previously described.[3,13,14,15,16,17,18] Although

    purpuric CD is not among the common clinical presentations of

    textile CD, it is not an atypical and extraordinary manifestation. In

    our experience, purpuric CD to clothing is more frequent than

    previously reported.[3,19,20] This phenomenon could be due in part

    to the climatic factors in Israel, where the hot and humid climate

    favors profuse sweating and thus enhances the exposure to the

  • 7/28/2019 Atypical and Unusual Clinical Manifestations of Contact Dermatitis to Clothing

    9/12

    Papular CD to textiles is a rare phenomenon. Follicular and

    papular lesions are reported in two patients with textile dermatitis

    causes by formaldehyde,[21] and a dermal reaction is noted with

    Disperse Blue 106.[22] It is of interest that in our patient the papular

    eruption also has purpuric features. The purpura is demonstrated

    histologically both in a lesional biopsy and in the biopsy from apositive patch test to Kaurit S. Admixture of purpura with papules is

    observed also in our patient with purpuric contact dermatitis (Case 3).

    Similar features of papules and purpura are described in the patients

    observed by Khanna.[23] It can be speculated that under certain

    circumstances strong allergens trigger an influx not only of

    lymphocytes but also of erythrocytes in the inflammatory infiltrate.

    Textile dermatitis with purpuric papules can resemble granuloma

    annulare, papular dermatitis, dermatitis herpetiformis, and mycosis

    fungoides and has to be differentiated from these entities.

    Pigmented CD is an atypical manifestation of textile CDoccasionally described in case reports.[25,26,27] Pigmented

    clothing dermatitis has been related to hypersensitivity to dispersedyes [3,16,18,28] and to an azo dye coupling component agent,

    Naphthol AS.[29] In our case, the pigmented patches are pruritic and

    appear without previously discernible eczematous lesions, in contrast

    with the findings of Ancona Alayon et al.[29] In their series the

    Naphthol AS pigmented CD presents with spotted hyperpigmentation

    on the exposed areas but without pruritus. The hyperpigmentation is

    most pronounced in individuals with dark complexions, as we also

    observe. The histological features included melanocyte proliferation,

    incontinence of pigment, and various degrees of damage to the basal

    layer.

    In the literature, phototoxic reactions to textiles[30] and contact

    depigmentation from the textile azo dye, Solvent Yellow 3, have been

    reported.[31]

    Apart from fiberglass, which can contaminate clothes and induce

    irritant, pruritic, contact dermatitis,[33] pruritus and excoriations are

    seldom mentioned as a part of the clinical manifestation of clothing

    CD.[3,33] Our patient demonstrates that pruritus and excoriationwithout dermatitis in the initial stages may also be a rare form of

    hypersensitivity to textile dyes and resins. Indeed she has undergone

    a thorough and expensive workup for generalized pruritus prior to

    patch testing.

    Although intolerance to wool and synthetic fibers are well

    known in atopic dermatitis,[34] childhood atopic dermatitis-like,

    allergic, CD reactions with lichenification, related to hypersensitivity

    to textile dyes or resins, are not documented. Our patient displays the

    features of chronic dermatitis with lichenification at areas reminiscent

    of the distribution of lesions in atopic patients. The triggering agentin the incriminated textile cannot be defined, but the clinical course

  • 7/28/2019 Atypical and Unusual Clinical Manifestations of Contact Dermatitis to Clothing

    10/12

    demonstrates the relevance of the suspected clothing.

    Other unusual forms of textile dermatitis to dyes and resins

    described in the literature include pustular lesions[3] and large,

    erythematous patches with desquamation.[6] Textile CD presenting

    as lichen amyloidosis, with hyperkeratotic papules and plaques andpositive patch tests to fragrance mix, formaldehyde, and

    formaldehyde resins has been described recently.[25]

    Our series of patients with allergic textile contact dermatitis

    demonstrates the atypical and unusual clinical presentations of

    allergic contact dermatitis to clothing. It should be noted that apart

    from the well-delineated clinical forms such as EM-like contact

    dermatitis, pigmented contact dermatitis, pruritus, and excoriation,

    mixed forms including papular and purpuric lesions, and purpuric and

    pigmented lesions can be also present. Being familiar with the typical

    and unusual forms of textile contact dermatitis allows more rapid andprecise diagnosis of clothing-related, contact dermatitis, which is not

    uncommon.
