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...

The authors present a classic case of Churg-Strauss syndrome with an exuberant clinical picture in a 34-year-old woman. She showed the following diagnostic criteria: asthma, polyneuropathy, rhinopathy, marked eosinophilia, positive p-ANCA with a perinuclear pattern, and skin histopathology results suggestive of vasculitis with eosinophils. There was a good response to prednisone, dexamethasone pulse therapy, and cyclophosphamide.

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.

Methotrexate-related lymphoproliferative disorder (MTX-LPD) is a rare disorder caused by long-term MTX therapy for autoimmune diseases. There has been no report of the dermoscopic features of MTX-LPD to date. A 64-year-old female presented with a slightly elevated indurated erythematous plaque with scales on her right thigh. The patient had been treated for rheumatic arthritis with MTX and prednisolone for more than 15 years, and 18 mg/week MTX without prednisolone had been administered in the last year. Dermoscopy revealed dotted vessels and glomerular vessels on pink homogeneous areas and multiple surface scales...

Bullous pemphigoid (BP) is a blistering autoimmune disease mainly observed in elderly patients. Several triggers are known for this autoimmune disease and some drugs are known to be a cause of BP. However, there are only few case reports on the induction of BP under adalimumab therapy. Other autoimmune diseases, such as lupus erythematosus, are also known to occur under TNF inhibition. Here, we report on an 81-year-old patient who received adalimumab for ulcerative colitis and subsequently developed BP. Other causes of BP (tumors, other drugs, viral or toxoplasma infections) were excluded...

Basal cell carcinoma (BCC) is the most common cancer in humans worldwide. Many highly specific dermoscopic criteria for BCC are well established in the literature. On the contrary, other malignant or benign skin tumors may mimic BCC by exhibiting similar or even the same dermoscopic features and therefore obscuring the diagnosis of BCC in certain situations. We herein report a case of BCC with dermoscopic features of both BCC and desmoplastic trichoepithelioma (DT). We would like to remind of the often neglected differential diagnosis of DT in a lesion with arborizing vessels and otherwise unusual dermoscopic presentation...

Plantar warts account for 30% of all cutaneous warts. These lesions could be very painful, especially if the lesion is located over pressure sites such as the metatarsal head. Plantar wart treatment remains a challenging therapeutic problem. A 67-year-old immunocompetent nonsmoking man presented with a large mosaic plantar wart on his right foot. The lesion had been present for 5 years. Several cryotherapy sessions (a total of 6 procedures) had been performed with no success. The lesion was therefore treated with a 5-fluorouracil (5-FU) regimen and then with a topical combination of 5-FU and salicylic acid, but also these approaches failed...

Background: Prurigo nodularis is a condition of unknown origin defined by papulonodular eruption and intense pruritus. Hodgkin lymphoma often presents nonspecific initial symptoms. An association between systemic malignancy and cutaneous manifestations has long been documented. We report a case of prurigo nodularis as a first presentation of Hodgkin lymphoma. Case: A 35-year-old woman presented with a 2-year history of pruritus. Previously diagnosed with bedbugs, the pruritus persisted even after insect eradication, with the appearance of papulonodular lesions consistent with chronic prurigo...

Porphyria cutanea tarda (PCT) is a cutaneous porphyria that presents later in life with cutaneous findings in sun-exposed sites. We report a complex case of PCT in a 67-year-old woman with an unusual constellation of cutaneous findings: scleroderma, acquired ichthyosis, and nonscarring alopecia. Possible triggers for her PCT include tamoxifen treatment for breast cancer and carrier status of the hemochromatosis gene. High-dose chloroquine was used to successfully achieve clinical remission and normalize her uroporphyrins...

Panniculitis is an uncommon skin eruption observed in patients with dermatomyositis (DM)/clinically amyopathic dermatomyositis (CADM), especially in anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive DM. We present here a 51-year-old Japanese woman with an anti-MDA5 antibody-positive DM who initially had cellulitis-like erythema on her right mandible. Histopathological findings showed a subcutaneous lobular infiltration of lymphocytes. The patient developed typical skin eruptions of DM/CADM, rapidly progressive interstitial lung disease, and severe muscle weakness 2 weeks after the first visit...
