Lucio phenomenon is a rare vasculopathy that can occur in patients with Hansen disease, particularly diffuse lepromatous leprosy. It is characterized by retiform purpura and necrotic ulcerations, most commonly affecting the extremities. Diagnosing Lucio phenomenon can be challenging, especially when secondary bacterial infections occur. We report a patient with Lucio phenomenon who presented with acute necrotizing fasciitis of his left upper extremity and a 10-year history of chronic ulcerations. Shortly following admission, he also developed acute kidney injury. The necrotizing fasciitis was treated with prompt surgical debridement and intravenous antibiotics. Biopsy and PCR of a right upper extremity ulcer confirmed the presence of Mycobacterium lepromatosis. Multidrug therapy and prednisone were used to treat the Lucio phenomenon. After initiating treatment, no new lesions developed, kidney function improved, and the patient underwent successful skin graft of his left upper extremity. Although corticosteroid use is controversial, our patient's marked response to multidrug therapy with prednisone highlights the importance of this regimen in severe presentations of Lucio phenomenon. To the best of our knowledge, only two other cases of Lucio phenomenon confirmed to be caused by M. lepromatosis have been reported in living patients (rather than retrospectively identified post-mortem), underscoring the importance of the presented clinical course and treatment regimen.

COVID-19 ,SARS-CoV-2 ,cutaneous manifestations - Abstract
The severe acute respiratory syndrome coronavirus two (SARS-CoV-2), which causes the 2019 coronavirus disease (COVID-19), has infected patients worldwide. Physicians have increasingly identified cutaneous findings as a significant clinical manifestation of COVID-19. In this review, we describe the clinical presentation, onset, duration, associated symptoms, treatment, and outcome of cutaneous manifestations thus far reported to be related to COVID-19. We have included data from 63 studies and subdivided reported cutaneous manifestations into the categories of viral exanthem, urticarial, vesicular, chilblains/chilblains-like, non-chilblains vasculopathy-related, pityriasis rosea-like, erythema multiforme-like, Kawasaki/Kawasaki-like disease, and others. Physicians should be aware of the known common cutaneous manifestations of COVID-19 and future research is required to better understand the pathophysiology and prognosis of each COVID-19-related skin manifestation.

BackgroundStevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are two of the most severe dermatologic emergencies. Although pregnant women comprise a subset of individuals at risk for SJS and TEN development, little is known with regard to outcomes and treatment.ObjectiveThis study aimed to conduct a systematic review to characterize the risk factors, outcomes, and treatment of SJS and TEN in pregnant patients and newborns.MethodsA primary literature search was conducted using PubMed in September 2019, using the following search terms entered in separate pairs: pregnant or pregnancy and stevens-johnson or SJS or toxic epidermal necrolysis. Reviews, studies in a language other than English, and articles not including pregnant patients were excluded.ResultsTwenty-six articles were included for review, including a total of 177 patients. The average maternal age for a reaction was 29.9 years, gestational age was 24.9 weeks, and time to reaction after drug initiation was 27.5 days. Approximately 85% of pregnant women in this review were infected with HIV. The most common causative medications were antiretroviral therapy (90% of all cases), antibiotics (3%), and gestational drugs (2%). Of the 94 cases in which outcome data were available, the survival rates of pregnant women and newborns after delivery were 98% and 96%, respectively. Withdrawal of the offending agent and supportive care was often sufficient for treatment, but antibiotics, steroids, and intravenous immunoglobulin were implemented in some cases. Complications included preterm labor, vaginal stenosis, and vaginal adhesions.ConclusionGiven the predominance of studies focusing on the subset of pregnant patients who are infected with HIV, SJS and TEN is most commonly reported in young patients after antiretroviral therapy, primarily nevirapine. Overall mortality is lower than that of the general population, but similar to the expected mortality rates of younger adults. Early recognition and withdrawal of the offending agent is essential to mitigate the distinct consequences of these conditions in the pregnant population.

Thiotepa is a common alkylating agent known to precipitate cutaneous reactions consistent with toxic erythema of chemotherapy, including erythema and hyperpigmentation. Herein, we describe an atypical case of malignant intertrigo involving preferential erythema and desquamation not only of skin folds but also of occluded areas after thiotepa-based conditioning. The diagnosis was complicated by concurrent stomatitis and oral petechiae in the setting of autologous stem cell transplant 11 days prior for diffuse large B-cell lymphoma. Histopathological examination from two cutaneous sites demonstrated epidermal dysmaturation and eccrine gland necrosis consistent with thiotepa-induced desquamation and not Stevens-Johnson syndrome or graft-versus-host-disease. Malignant intertrigo can present with extensive cutaneous involvement, as evidenced by our patient who had 25% body surface area affected. Mucosal involvement is common with most chemotherapeutic regimens and its presence should not deter the astute clinician from consideration of a diagnosis of toxic erythema of chemotherapy. No further interventions were needed and the patient healed spontaneously.

We describe adult-onset Kawasaki disease (KD) and review clinical manifestations and treatment guidelines. Our patient is a 20-year-old female who initially presented to an outside hospital for fever, cervical lymphadenopathy, malaise, exudative tonsillitis, and skin eruption. She received antibiotics for suspected exudative pharyngitis, but experienced continued fevers and presented to the UCLA emergency room one week later. She had diffuse petechial macules coalescing into reticulated patches, fingertip peeling, conjunctival injection, oral erosions, and tongue swelling. Despite her age, given her constellation of symptoms, a diagnosis of typical KD was favored. She was started on high dose aspirin and IVIG, with improvement of rash and conjunctivitis. She was discharged on 325mg of aspirin daily with close follow-up. This case highlights the challenge of diagnosing KD in adults. Although this patient had classic symptoms, she was likely misdiagnosed because KD is rare in adults and without validated criteria. Our patient met the pediatric criteria, suggesting these should be considered when clinical suspicion for adult-onset KD is high. Adult-onset KD is most commonly misdiagnosed as toxic shock syndrome or drug-induced hypersensitivity syndrome and these are important to rule-out. Treatment with high-dose aspirin and IVIG is well established and should be initiated promptly.

Verrucous venous malformation, also known as verrucous hemangioma, is a superficial vascular malformation with a variable degree of hyperkeratosis that is composed of capillaries and veins in the dermis and sometimes subcutaneous tissue. We describe a 53-year-old man who presented with a large hyperkeratotic plaque of the left dorsal and plantar foot. Biopsy revealed verrucous acanthosis of the epidermis and a proliferation of thin-walled vessels in the dermis. We provide a brief review of the clinical and histopathologic presentation, differential diagnosis, and management of this rare entity.

Background: Erythema multiforme (EM), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are cutaneous hypersensitivityreactions that develop in response to specific triggers such as medications and certain infections. Vaccines, which undergo rigorous safety testing prior to use in humans, are a rare cause of SJS/TEN and little is known about the frequency of such events and corresponding pathogenesis.Objective: Herein, we discuss a case of suspected TEN in a 19-year-old woman who received the meningococcal B vaccine (the first report of such an association) and conduct a systematic review of the associated literature. We also discuss management of this patient with a single dose of etanercept.Methods: Relevant literature was searched using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method.Results: A total of 29 articles reporting EM, SJS, or TEN following vaccination were included from >5 countries. Of the 29, 22 articles reported EM, 6/29 reported SJS, and 4/29 reported TEN (3 articlesreported cases of both EM and SJS/TEN).Conclusions: We suggest consideration of vaccines as an etiology for cases of SJS or TEN that begin with an EM-like presentation, and provide further evidence for the use of etanercept as a viable treatment for TEN.

ichthyosis ,collodion ,hyperkeratosis ,genodermatosis ,ABCA12 - Abstract
The term, autosomal recessive congenital ichthyosis (ARCI), describes a group of rare genetic skin diseases of cornification involving hyperkeratotic scaling at birth. The defective skin barrier function may lead to dehydration, body temperature instability, and high susceptibility to infections. In most cases of ARCI, neonates are born with a collodion membrane covering the body, often presenting with ectropion and eclabium. We report a premature female neonate presenting with hyperkeratotic scaling at birth without a collodion membrane. She was managed with placement in a humidified isolette, prophylactic antibiotics, dilute bleach baths, petrolatum ointment, and artificial eye drops. By the fourth week of life, there was marked improvement in her skin with the large, brown, plate-like scales on the trunk and extremities becoming lighter in color and finer in appearance. The ichthyosis genetic panel showed mutations in the ABCA12 gene resulting in the lamellar ichthyosis phenotype of ARCI. Our literature review revealed at least 28 patients with ARCI who were not born as collodion babies. Although collodion babies are a hallmark of most ARCI cases, clinicians should be aware of neonates with ARCI born without a collodion membrane and expedite appropriate workup and treatment.

Mycoplasma pneumoniae-induced rash and mucositis ,MIRM ,pustulosis - Abstract
Mycoplasma pneumoniae-induced rash and mucositis (MIRM) is a disease characterized by mucosal involvement with variable cutaneous manifestations induced by M. pneumoniae infection. Previously reported rash morphologies include vesiculobullous, targetoid, papular, macular, and morbilliform lesions. Pustulosis is a rare presentation of MIRM that has been described only once before in the literature to our knowledge. We report a case of a 13-year-old boy presenting with a pustular skin eruption induced by Mycoplasma infection. Ours’ is the second report of MIRM, to our knowledge, presenting with pustulosis and the first, to our knowledge, to first to describe the histopathologic finding of perifollicular neutrophilic infiltration in MIRM.

Many cases of superinfected hidradenitis suppurativa (HS) involve multiple species of bacteria, but gas-producing infections are rare and can complicate the clinical picture. Additionally, recognizing squamous cell carcinoma (SCC) as a complication of longstanding HS is imperative. Herein, we present a unique case of a severe emphysematous HS that was initially mistaken for Fournier gangrene and eventually diagnosed as superinfected SCC.

- Abstract
A 34-year-old woman was diagnosed with Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), most likelyrelated to a reaction to allopurinol.The patient presented with a 2-week history of a painful pruritic rash that started on her back and progressed to the rest of her body over a five-day period. The eruption started after several new drugs were started, including allopurinol for hyperuricemia. On physical examination, the patient had a diffuse morbilliform eruption and geometric intact bullae limited to the boundaries of tattoos.Most presentations of DRESS include a morbilliform eruption. However, DRESS does not commonly present with bullae. There have been no known reported cases of bullae forming in the area of tattoos in cases of DRESS. This unique presentation suggests that a component of the tattoo or tattooing process alters the cutaneous immune response, creating an immunocompromiseddistrict. This alteration may promote a greater localized reaction in the setting of widespread skin involvement in DRESS.

Eltrombopag is a thrombopoietin mimetic used for the treatment of thrombocytopenia in patients with chronic immune thrombocytopenia, hepatitis C patients undergoing antiviral therapy, and thrombocytopenia secondary to aplastic anemia that is refractory to immunosuppressive therapy. We report a case of a 25-year-old man with a history of aplastic anemia who presented with fever and a monomorphic papular rash. Subsequent labs, biopsy, and clinical course favored drug-induced cutaneous toxicity, with eltrombopag as the likely culprit. Eltrombopag is generally well-tolerated; however, clinicians should be aware of the possibility of dose-independent drug-induced cutaneous toxicity with this medication. This report reviews the mechanism and use of eltrombopag along with a summary of associated adverse cutaneous reactions.

pemphigus vulgaris ,keloids ,infection - Abstract
Pemphigus vulgaris is an immunobullous disease characterized by intraepidermal blister formation. These blisters eventually rupture, leaving erosions that are slow to heal, often leaving hyperpigmented patches, but no scars. We describe a case of a 67- year-old man with pemphigus vulgaris who suffered severe keloidal scarring after the pemphigus lesions became infected. His keloids were treated with intralesional corticosteroids with some improvement. Pemphigus vulgaris, a process confined to the epidermis, may lead to scarring in predisposed individuals, particularly if infection occurs.
