Cutaneous Sarcoidosis

Hypopigmented Cutaneous Sarcoidosis Responsive to Minocycline

By | Case Reports, SOC Manuscripts | No Comments

Hypopigmented patches and plaques are a rare presentation of cutaneous sarcoidosis. JDD authors describe a case of generalized hypopigmented cutaneous sarcoidosis that showed good response to minocycline therapy.

Introduction

A 58-year-old African-American male with a past medical history of hypertension, diabetes mellitus, tobacco use, glucose-6-phosphate dehydrogenase (G6PD) deficiency, and hyperlipidemia presented with a two-year history of asymptomatic light spots on his trunk and upper extremities. He reported a history of cutaneous sarcoidosis a decade prior, characterized by erythematous papules and plaques that had regressed with hydroxychloroquine therapy. The newer light patches were not responsive to mid-potency topical steroids or tacrolimus 0.1% ointment. Review of systems was negative. The patient denied any new medications or history of travel outside of the metropolitan area.

 

Physical examination of the skin was significant for multiple hypopigmented patches on the face, neck, and extremities; hypopigmented plaques on the back (Figure 1); and annular plaques of hypopigmented papules on the chest and abdomen (Figure 2). The lesions were not hypoesthetic. There was no lymphadenopathy and physical exam was otherwise unremarkable.

 

A biopsy from the left arm showed a superficial and deep multinodular granulomatous infiltrate sparing the epidermis (Figure 3). The granulomas were predominantly composed of epithelioid histiocytes with a few scattered lymphocytes (Figure 4). Special stains for microorganisms were negative. There was no appreciable epidermal change or pigment incontinence. The histopathological picture was consistent with recurrent cutaneous sarcoidosis.
Computed tomography of the chest with and without contrast showed no evidence of active pulmonary sarcoidosis or lymphadenopathy. An ophthalmologic exam, abdominal ultrasound, and spirometry were within normal limits, as were serum cal cium and angiotensin-converting enzyme (ACE) levels.

 

Because the patient’s skin manifestations had resolved with hydroxychloroquine in the past, this treatment was restarted at 200 mg twice-daily. Unfortunately, laboratory monitoring revealed hepatic transaminitis and mild anemia 2 months into the treatment course, corresponding with only minimal improvement of the hypopigmented plaques, necessitating discontinuation of hydroxychloroquine. Minocycline at a dose of 100 mg twice daily was then initiated 4 months after normalization of liver function tests. After 5 months of treatment, all hypopigmented patches, papules, and plaques had completely or partially repigmented and were appreciably smoother and flatter (Figures 5 and 6). The patient tolerated the medication well with no adverse effects.

Discussion

The skin is one of myriad organs potentially affected by sarcoidosis, a multisystem idiopathic disorder characterized histologically by infiltration of noncaseating granulomas. Cutaneous manifestations of sarcoidosis are protean, including papules and plaques of various morphology and distribution, subcutaneous nodules, pruritus, ichthyosis, erythroderma, ulceration, verrucosis, nail disease, and infiltrative scars.1 In the United States, sarcoidosis is more common in African-Americans than in other ethnic groups, and cutaneous manifestations in individuals of African descent are more likely to be atypical.2

In 1973, Cornelius et al reported 4 patients who presented with hypopigmented and depigmented patches and plaques that showed the naked tuberculoid granulomas characteristic of sarcoidosis on skin biopsy.3 The distribution in these cases was variable, with generalization in one patient and localization to the face, legs only, or legs and arms in the other three. Histologically, no difference in epidermal melanocyte count was noted between affected and unaffected skin, but relative hypomelanosis of the malphigian and corneal layers was appreciated. All patients had multisystem disease. Four years later, Hubler described a “hypomelanotic canopy” in a woman with lupus pernio and lymphadenopathy whose hypopigmented patches overlay deep subcutaneous nodules on the arms.4Biopsy of an enlarged lymph node revealed epithelioid granulomas that were reduplicated on skin biopsy. Interestingly, cutaneous hypopigmentation lacking any histological evidence of granulomatous dermatitis has also been observed in the setting of systemic sarcoidosis;5,6 this highlights the need for vigilant continued surveillance when the clinical index of suspicion for sarcoidosis is high and biopsy is noncorroborative.

 

The etiopathogenesis of hypopigmentation in sarcoidosis, like the disease itself, is unknown. Theories regarding the likely mul tifactorial cause of sarcoidosis center around T-cell—mediated autoimmunity, genetic predisposition, and aberrant response to bacterial or other antigens; the evidence for each has been extensively reviewed elsewhere.1,7 The rare cutaneous hypopigmentation seen in dark-skinned individuals with sarcoidosis appears to represent a melanopenic hypomelanosis, as opposed to postinflammatory hypopigmentation or melanocytopenia.3,4,8 In our patient, there were no epidermal changes, interface in flammation, or melanin-containing dermal macrophages to suggest postinflammatory dyspigmentation.

 

Minocycline represents an attractive alternative treatment for chronic sarcoidosis in patients who might otherwise be treated with long-term corticosteroids, antimalarials, methotrexate, or other immunosuppressants. The tetracycline class of antibiotics has previously demonstrated utility in a variety of dermatoses and autoimmune-connective tissue diseases, and may be particularly efficacious for granulomatous skin conditions.9,10 Tetracyclines have specifically shown efficacy in the treatment of granulomatous periorificial dermatitis, cheilitis granulomatosa, granulomatous rosacea, and silicone granulomas.11-14 More recently, tetracyclines proved beneficial in treating granuloma annulare (GA), an entity often with significant clinicopathological overlap with cutaneous sarcoidosis.15,16 Marcus et al showed that, in combination with rifampin and ofloxacin, 3 to 5 courses of monthly minocycline therapy led to complete clearance of GA in 6 patients, half of whom had generalized disease.15 In this series, the rationale for selection of the same triple combination antimicrobial therapy as that used for paucibacillary leprosy (PBL) was that the clinical and histological similarities between PBL and GA might impart an equally similar response to treatment. The same logic could be extrapolated further to include patients with cutaneous sarcoidosis as candidates for a treatment regimen, including minocycline, with or without rifampin and ofloxacin.

 

Minocycline as monotherapy was efficacious for the treatment of chronic cutaneous sarcoidosis in an open observational study of 12 patients by Bachelez et al.17 The cutaneous manifestations of patients in the Bachelez group included classic plaques, papulonodules, subcutaneous nodules, and lupus pernio. Ten of 12 patients completely or partially responded to treatment, which was generally well tolerated except for drug hypersensitivity syndrome in one patient with a history of other autoimmune diseases. Park et al later reported a patient with cutaneous, lacrimal gland, pulmonary, and ocular (choroidal) sarcoidosis that responded to minocycline.18

Miyazaki et al described a patient with a unique presentation of muscular sarcoidosis of the limbs, as well as uveitis and pulmonary disease, in whom clinical response to minocycline was paralleled by normalization of an elevated ACE level.19 The patient relapsed off of minocycline, but rapidly responded to reintroduction of the medication. Immunohistochemical staining of muscle biopsy specimens for Propionibacterium acnes showed multiple small particles within granuloma macrophages and giant cells, substantiating the theory that sarcoidosis is an infectious disease or an aberrant immunologic response to bacteria. Evidence for the role of other infectious agents in sarcoidosis, especially Mycobacterium tuberculosis, has been mixed and inconclusive.20 That sarcoidosis is purely an infectious disease is certainly within the realm of possibility,21 but the recurrence of disease once antibiotics are discontinued argues against this theory.19 An alternative explanation is that the benefits of tetracyclines in sarcoidosis and other autoimmune diseases are derived more from their nonantibiotic immunomodulating properties. The anti-inflammatory properties ascribed to minocycline include inhibition of T cell activation, proliferation, and transmigration as well as expression of nitric oxide synthetase and matrix metallopeptidase 9 (MMP-9).9Furthermore, tetracyclines have been shown to inhibit granuloma formation in vitro.22

 

Conclusion

The role of tetracyclines in the therapeutic armamentarium of sarcoidosis, especially in those who cannot tolerate antimalarials or other immunomodulating medications, is likely to expand. Whether minocycline is particularly effective for the hypopigmented variety of cutaneous sarcoidosis remains to be seen.

Pemphigus Foliaceus

Psoriasiform Pemphigus Foliaceus in an African American Female: An Important Clinical Manifestation

By | Case Reports, SOC Manuscripts | No Comments

JDD authors document and highlight this atypical psoriasiform presentation of Pemphigus Foliaceus in a patient with skin of color to raise awareness and improve diagnosis and outcomes.

Case Report

A 50-year-old African-American woman presented to the dermatology clinic with a pruritic eruption of 3 years’ duration that began as discrete plaques on the inframammary folds and subsequently spread towards the mid-chest, ears, back, elbows, knees, and scalp. Past treatments by other clinicians included clotrimazole cream and a topical corticosteroid of unknown potency without significant improvement. She denied any new medications and was taking aspirin, divalproex, mirtazapine, cetirizine, venlafaxine, atorvastatin, and omeprazole.

On clinical examination, the patient had well-demarcated, pink, atrophic plaques and superficial erosions over the inframammary folds and mid-chest (Figures 1). She also had well-demarcated, hyperpigmented, hyperkeratotic scaly plaques over the abdomen, suprapubic region, elbows, knees, and back with sporadic small superficial blisters (Figure 2). Complete blood count, complete metabolic panel, rheumatoid factor, and antinuclear antibody were within normal limits. Rapid plasma reagin test was negative. Erythrocyte sedimentation rate was elevated at 54 millimeter/hour (reference range 0-22 millimeter/hour). A punch biopsy of the right abdomen was performed and revealed psoriasiform epidermal hyperplasia, focal parakeratosis, and acantholysis throughout the superficial spinous and granular layers (Figure 3). Only a sparse inflammatory infiltrate was present in the underlying dermis. These clinical and histological findings supported the diagnosis of pemphigus foliaceus (PF). Patient was started on 50 mg oral dapsone daily.

Discussion

Herein, we present a case of Pemphigus Foliaceus with a psoriasiform clinical presentation in an African-American patient. PF is an autoimmune skin disease caused by antibodies against the desmosomal glycoprotein, desmoglein 1.¹ Desmogleins, members of the cadherin family, serve to anchor epidermal desmosomes between adjacent keratinocytes and assist in epithelial differentiation.² Antibodies targeting desmoglein 1 result in acantholysis in the upper epidermis with limited separation in the basal layers and minimal mucosal involvement as desmoglein 1 is primarily expressed in the granular layer of the non-mucosal epidermis.¹ Patients present with scaly plaques on an erythematous base and fragile shallow blisters which are infrequently found intact; rarely, the condition can progress to exfoliative erythroderma.1,3 Initially, PF usually presents on the trunk, face, or scalp, but may subsequently involve other regions of the skin.1 Diagnosis may be confirmed with biopsy and direct immunofluorescence with intercellular IgG and C3 limited to the upper epidermis. Treatment includes oral and topical steroids, azathioprine, dapsone, and rituximab. The differential diagnosis for PF may include systemic lupus erythematosus, bullous impetigo, psoriasis, and seborrheic keratosis depending on the presentation.1

Physical exam findings in this patient were suggestive of PF due to the presence of superficial secondary erosions and “corn flake-like” scales, but psoriasis was included in the differential diagnosis due to the presence of discrete plaques with an erythematous border. PF is a relatively rare condition with a prevalence of less than 1 case per 100,000 and is about 5 to 10 times less common than pemphigus vulgaris.4 In contrast, psoriasis impacts approximately 2-4% of people in the United States.5 An endemic form of PF, fogo selvagem, has been reported in Brazil, Colombia, Peru, and Tunisia, while pemphigus vulgaris is more common in Mediterranean and Ashkenazi Jewish populations.4

We hypothesize that patients with psoriasiform presentations of PF may be misdiagnosed with plaque psoriasis. One author (JJ) has previous significant clinical experience with patients with skin of color and has seen other skin of color patients present with a psoriasiform manifestation of PF. PF and psoriasis share similar treatments including topical corticosteroids and immunosuppressants, and this may lead to underreporting of PF with psoriasiform manifestations. It is important to distinguish between these findings as there is evidence that ultraviolet light, a common treatment for psoriasis, may exacerbate PF.6,7 We performed a search of the published literature and identified one article that describes three patients with pemphigus erythematosus, a variant of PF, which was misdiagnosed as psoriasis.8 No identified articles described cases of PF with a psoriasiform presentation in patients with skin of color. We document and highlight this atypical psoriasiform presentation of PF in a patient with skin of color to raise awareness and improve diagnosis and patient outcomes.
