Though Crohn's disease primarily affects the gastrointestinal tract, cutaneous Crohn's disease of the vulva can occur in the absence of gastrointestinal symptoms, complicating the diagnosis. Once clinicians suspect cutaneous Crohn's disease, antibiotics and traditional immunosuppressants comprise initial treatment. Unfortunately, sometimes these therapies are not effective, or they provide only short-lived symptomatic improvement. A few case reports have found tumor necrosis factor-α inhibitors to be helpful in such refractory cases...

Multikinase inhibitors (MKIs) are a novel target therapy that offers promising long-term survival for patients with advanced-stage cancer. However, they cause a wide range of adverse reactions, skin and skin appendage being the most prevalent. Photosensitivity reactions are well-recognized effects from certain MKIs such as sunitinib and vandetanib. However, phototoxic reaction induced by pazopanib has never been reported. We present here the first case of pazopanib-induced phototoxic drug reaction in a patient with renal cell carcinoma...

Several case reports and retrospective studies have demonstrated that intralesional methotrexate (MTX) could be a very effective and safe alternative treatment of keratoacanthoma (KA). Here, we report a rapid clinical efficacy of two intralesional MTX injections (total dose 40 mg) that were performed 1 week apart in the treatment of a large KA lesion of the dorsal hand in a 99-year-old woman. The lesion, with a 3-cm major axis diameter and a thickness of 2 cm with a central ulceration had rapidly appeared on the right dorsal hand...

Proctosedyl® and Proctomyxin® are two commonly prescribed hemorrhoid therapies. Their topical application to the perianal region may be complicated by a local allergic contact dermatitis and subsequent autoeczematization reaction. We present three cases of an autoeczematization (ID) reaction to varying topical allergens found in Proctosedyl®/Proctomyxin®. It is our recommendation that physician and patient education, avoidance of allergens (or cross-reactants), and appropriate choice of topical corticosteroid is important in preventing and avoiding flares...

Sporotrichosis is an infection caused by fungi of the Sporothrix complex. The clinical lymphocutaneous presentation corresponds to the great majority of cases. With the increased incidence of sporotrichosis in the State of Rio de Janeiro, Brazil, atypical clinical forms have been reported with increasing frequency, usually associated with immunosuppression. We report the case of a 47-year-old female, with HIV and disseminated sporotrichosis, presenting molluscum-like skin lesions, as well as lung, nasal, and oral mucosa involvement...

We report the case of a 45-year-old female with generalized morphea (GM), who exhibited positivity for the anti-centromere antibody (Ab). She frequently developed multiple sclerotic skin lesions, whose histological findings were compatible with morphea. She demonstrated favorable responses to topical and oral steroids. Cases of GM associated with systemic sclerosis (SSc)-specific Abs (anti-Scl-70 Ab, anti-centromere Ab, and anti-RNA polymerase III Ab) have rarely been reported. The previously reported GM cases involving anti-SSc-specific Abs exhibited some skin manifestations of SSc, such as nailfold capillary changes...

Onychomycosis is the most frequent nail disease, with an estimated prevalence of 2-8%. Current treatment strategies include the use of oral and topical antifungals, despite low cure rates following these treatments. The objectives of this study were to assess the therapeutic response of patients with onychomycosis to 1,064-nm Nd:YAG laser treatment, the clinical evaluation method available for this therapy, and the possible side effects of this treatment. Twenty patients with onychomycosis underwent laser therapy...

A 94-year-old man consulted our hospital due to a rapidly growing tumor on the left cheek. The histological diagnosis of the tumor was basal cell carcinosarcoma, which was composed of intermingled epithelial and mesenchymal components. The former was basal cell carcinoma, while the latter was spindle cell sarcoma. The tumor was completely resected with a 3-mm margin and the patient remained free of local recurrence or distinct metastasis for 2 years. We report here a case of cutaneous basal cell carcinosarcoma and a review of the literature...

Granuloma gluteale infantum is a rare pediatric dermatological disorder of uncertain etiology. Suggested causes include fluorinated corticosteroids, Candida albicans , and irritant contact dermatitis. We present the case of a 3-year-old boy with recurrent episodes of granuloma gluteale infantum which resolved with treatment of his fecal overflow incontinence. As each recurrence correlated with a relapse of overflow incontinence, in this case the cause was irritant contact dermatitis from the liquid stool. This is the first reported case of recurrent granuloma gluteale infantum...

Atezolizumab is a humanized anti-PD-L1 immune checkpoint antibody that is currently used in many kinds of advanced carcinoma including metastatic non-small cell lung cancer. The cutaneous side effect profile reported only 20$ of the patients which had only mild maculopapular rash that required no treatment. There is no case report of anti-PD-L1 antibody-induced Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) eruptions. To the best of our knowledge, there is no case report of atezolizumab-induced SJS or SJS/TEN induced by anti-PD-L1 immune checkpoint antibodies...

Objective: The incidence of immune-related adverse events is growing as the use of checkpoint inhibitors is exponentially increasing. Cutaneous adverse events are among the most frequent immune-related adverse events. The purpose of this case report and literature review is to highlight psoriasis as a potential adverse event with need for early recognition. Case Report and Literature Review: We describe the case of a 65-year-old woman with psoriasis exacerbation while treated with nivolumab (anti-PD-1) for a stage IV melanoma...

We report the case of a patient suffering from hidradenitis suppurativa since puberty and complaining of chronic low back pain associated to altered sensitivity and muscular weakness in the right leg. A diagnosis of lumbosciatica was confirmed. Symptoms were not relieved after the use of nonsteroidal anti-inflammatory drugs and analgesics. A surgical decompression was then indicated but heavily debated. Indeed, extended inflammatory and fibrotic hidradenitis suppurativa lesions were located regarding the skin area eligible for the proposed surgery...

Inflammatory linear verrucous epidermal nevus (ILVEN) is an epidermal nevus that clinically and histologically mimics linear psoriasis. The pathogenesis of psoriasis has been widely investigated, with recent studies focusing especially on targeting proinflammatory cytokines such as IL-17A, TNFα, IL-23, and IL-12, while little is known about ILVEN. Since the treatment for ILVEN varies widely from the administration of topical ointment for psoriasis to invasive methods such as carbon dioxide gas laser, the differential diagnosis between ILVEN and psoriasis is necessary...

Decorative tattooing is a procedure in which exogenous pigment and/or dye is introduced into the dermis with the aim of creating a permanent skin decoration. The increasing prevalence of tattooed individuals leads to more reported tattoo-related complications. Pseudolymphomatous reaction is a benign reactive proliferation of lymphocytes that may uncommonly occur secondary to tattooing. We describe the clinical, histological, and molecular aspects of a pseudolymphomatous reaction to red tattoo pigment.

Annular elastolytic giant cell granuloma (AEGCG) is a rare granulomatous skin disease characterized by annular patches with slightly raised borders, hypopigmented and/or atrophic centers found mainly on sun-exposed skin. Histologically, it is characterized by phagocytosis of elastic fibers by multinucleated giant cells. The pathogenesis of the disease is unclear. We report a case of 55-year-old man with AEGCG in association with syphilis, whose condition improved when hydroxychloroquine sulfate and topical tacrolimus were administered over a 2-month period...

Checkpoint inhibitors are novel and promising treatment options for different types of cancer. Programmed cell death 1 (PD-1) inhibitors, such as pembrolizumab, have been shown to significantly raise the survival rates of disseminated malignant melanoma (MM). Autoimmune adverse reactions are very common in checkpoint inhibitors. We present 2 cases of bullous pemphigoid, as adverse reactions to pembrolizumab-treated MM.
