Rashes in the newborn period are common and most are benign. Infections should be suspected in newborns with pustules or vesicles, especially in those who are not well-appearing or have risk factors for congenital infection. Congenital cytomegalovirus infection can cause sensorineural hearing loss and neurodevelopmental delay. Skin manifestations of cytomegalovirus may include petechiae due to thrombocytopenia. The most common skin manifestations of early congenital syphilis are small, copper-red, maculopapular lesions located primarily on the hands and feet that peel and crust over three weeks. Erythema toxicum neonatorum and neonatal pustular melanosis are transient pustular rashes with characteristic appearance and distribution. Neonatal acne is self-limited, whereas infantile acne may benefit from treatment. Milia can be differentiated from neonatal acne by their presence at birth. Cutis marmorata and harlequin color change are transient vascular phenomena resulting from inappropriate or exaggerated dilation of capillaries and venules in response to stimuli.

A Series of 69 COVID-related Dermatoses With Biopsy, Immunohistochemistry With Anti-spike 3, in situ Hybridization and PCR: A Critical Reappraisal of Viral Involvement in COVID-19 Skin Lesions.
BACKGROUND
Despite the large number of articles published on skin lesions related to COVID-19, clinicopathological correlation has not been performed consistently and immunohistochemistry to demonstrate spike 3 protein expression has not been validated through RT-PCR.
MATERIAL AND METHODS
We compiled 69 cases of patients with confirmed COVID-19, where skin lesions were clinically and histopathologically studied. Immunohistochemistry (IHC) and RT-PCR was performed in skin biopsies.
RESULTS
After a careful review of the cases, 15 were found to be dermatosis not related to COVID-19, while the rest of the lesions could be classified according to their clinical characteristics as vesicular (4), maculopapular eruptions (41), urticariform (9), livedo and necrosis (10) and pernio-like (5). Although histopathological features were similar to previously reported results, we found two previously unreported findings, maculopapular eruptions with squamous eccrine syringometaplasia and neutrophilic epitheliotropism. IHC showed in some cases endothelial and epidermal staining but RT-PCR was negative in all the tested cases. Thus, direct viral involvement could not be demonstrated.
CONCLUSIONS
Despite presenting the largest series of confirmed COVID-19 patients with histopathologically studied skin manifestations, direct viral involvement was difficult to establish. Vasculopathic and urticariform lesions seem to be those more clearly related to the viral infection, despite IHC or RT-PCR negative results failed to demonstrate viral presence. These findings, as in other dermatological areas, highlight the need of a clinico-pathological correlation to increase knowledge about viral involvement in COVID-19 skin-related lesions.

Review
BACKGROUND
Skin manifestations' true prognostic value, and clinical and epidemiological pictures in SARS-CoV-2 infection in African populations are poorly described and understudied. More familiarity with COVID-19 cutaneous manifestations may aid in early clinical diagnosis or guide prognosis.
METHODS
In this literature review, we looked for potential studies published from December 2019 to March 2023 on COVID-19 cutaneous lesions in African populations. Our key questions were focused on the prognostic values of cutaneous manifestations related to COVID-19.
RESULTS
Our findings show that cutaneous manifestations of COVID-19 vary by country and severity of COVID-19, primarily multisystem inflammatory syndrome (MIS). Significant differences were also found between various dermatological lesions, primarily MIS, erythema multiforme-like, livedoid, vesicular, or varicella-like rashes, urticarial, maculopapular or morbilliform rashes, and chilblain-like or pernio-like rashes. There were 47.5% (115/242) of MIS cases reported in nine published African studies. Our findings also revealed that MIS may be diagnosed in 2-7 days due to early onset rash. Advanced age, obesity, diabetes, cardiovascular disease, HIV, tuberculosis, asthma, atopic disease, underweight, malnutrition, and malignancy were found to be associated with COVID-19 cutaneous manifestations in African populations.
CONCLUSIONS
COVID-19-related skin manifestations in African populations are important as a driving force in COVID-19 prognosis.

Review
BACKGROUND Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare hypersensitivity reaction involving the skin and various visceral organs; the kidneys are the second most affected organ. Many drugs are reported to be associated with DRESS, particularly antiepileptic agents and allopurinol. Certain human leukocyte antigen (HLA) haplotypes, in combination with a particular drug, can further contribute to an increased risk of DRESS. Symptoms often develop 2 to 8 weeks after drug initiation. If diagnosis is delayed, DRESS can be a life-threatening condition. CASE REPORT We present cases of 2 patients. The first patient was an 86-year-old Polish woman who developed acute kidney injury and skin lesions with accompanying leucocytosis and eosinophilia during long-term antibiotic therapy with piperacillin/tazobactam and ciprofloxacin. The second patient was a 37-year-old Asian woman with predialysis chronic renal disease stage V in the course of IgA nephropathy. Two weeks after starting allopurinol in a standard dose, she presented with maculopapular rash, facial edema, fever, liver injury, and eosinophilia. Renal function started to deteriorate, but she did not require dialysis. In both cases, the discontinuation of the above-mentioned drugs and the introduction of steroid therapy and intravenous immunoglobulins allowed for clinical improvement and recovery. In the second case, the extended 4-locus HLA typing was performed retrospectively, and allele HLA-B*5801 was found. CONCLUSIONS Due to the rare occurrence and heterogeneous manifestation of DRESS, its diagnosis can pose many difficulties. In-depth analysis of symptoms, medicines taken, and laboratory findings enable the implementation of appropriate treatment and recovery.

INTRODUCTION
Since the beginning of the pandemic, many skin manifestations associated with COVID-19 have been reported. New reports show that COVID-19 can lead to autoimmune diseases (AIDs) and autoinflammatory diseases, especially dermatological.
METHODS
A prospective study was conducted by the dermatology department of the Centre Hospitalier Universitaire Ibn Rochd (CHU Ibn Rochd) of Casablanca in Morocco since the beginning of the pandemic including 18 patients with COVID-19-related skin manifestations.
RESULTS
Eighteen cases were collected with confirmed SARS-CoV-2 infection. The mean COVID score was 0.7. A percentage (94.44%) of the cases had general symptoms. Skin involvement was variable, mainly maculopapular rash (44.44%), purpura (27.77%), urticaria, varicelliform rash, necrotic lesions of the face, and pityriasis rosea Gibert (PRG)-like lesions. Mucosal involvement was found in 50%. Viral reactivation was found in 5.55%. Telogen effluvium was found in 22.22%. Moreover, AID was triggered by COVID-19: lupus (11.11%), associated with antiphospholipid syndrome (APL Sd) (5.55%), psoriasis (11.11%), alopecia, and pemphigus. Severe toxidermia was potentiated by SARS-CoV-2 infection (22.22%): Stevens-Johnson syndrome (Sd), acute generalized exanthematous pustulosis (APEG), and drug reaction with eosinophilia and systemic symptoms (DRESS).
CONCLUSION
The interest of this work is to report our experience during the COVID-19 pandemic to understand some pathophysiological mechanisms of its dermatological manifestations and to draw the attention of clinicians to the link of this infection with autoimmune and autoinflammatory diseases and toxidermia.

BACKGROUND
COVID-19, the widely recognized and highly contagious respiratory tract infection, has had a substantial impact on the field of dermatology since its emergence in 2019. SARS-CoV-2, the causative virus of COVID-19, is classified as an RNA virus. Various skin-related symptoms have been reported in patients with COVID-19, most notably the distinctive purple-red acral rash resembling chilblain lesions, commonly referred to as 'COVID toe'; similarly, skin-related symptoms have been observed in connection with other RNA viruses.
OBJECTIVES
To explore the relationship between RNA viruses and their associated vascular cutaneous manifestations vs. those observed in patients infected with SARS-CoV-2.
METHODS
A systematic literature review was conducted using PubMed and medical subject heading terms related to RNA viruses and related skin manifestations.
RESULTS
In total, 3994 patients diagnosed with COVID-19 presenting with skin rashes were included. Chilblain-like lesions were most frequently observed (30.2%), followed by erythematous maculopapular/morbilliform rashes (9.1%) and urticarial rashes (4.7%). Of 8362 patients diagnosed with RNA viruses, more than half of the skin findings reported were erythematous/maculopapular/morbilliform rashes (52.3%), followed by unspecified (11.3%) and purpuric rashes (10.6%).
CONCLUSIONS
When comparing RNA viral infections with COVID-19 infection, we observed similarities in the reported skin manifestations and their presumed pathways, with many implicated in the proinflammatory response. Owing to the wide range of cutaneous symptoms associated with RNA viruses and our currently limited understanding of the underlying mechanisms, additional research is warranted to investigate the pathology behind viral-induced skin lesions.

INTRODUCTION
In prostate cancer, androgens are key in the growth of both normal prostate and cancer cells. Abiraterone acetate inhibits CYP17, an important target in prostate cancer given its central role in the production of adrenal and tumor-derived androgens. Although abiraterone is generally well tolerated, common adverse effects such as hypertension, hypokalemia, and hepatotoxicity have been reported.
CLINICAL CASE
We present the case of an 83-year-old Mexican man with high-volume EC IV prostate cancer resistant to castration, orchiectomy, and bone, liver, and lung metastases. First-line treatment with the CHAARTED scheme was indicated, by patient decision refuse chemotherapy treatment. On the fourth day of starting treatment, he developed pruritic erythematous macular skin lesions and urticaria on the posterior chest that resolved spontaneously. A generalized erythematous and pruritic maculopapular rash appeared 12 days after starting abiraterone, for which she was referred to allergies.
MANAGEMENT AND RESULTS
An oral provocation test was performed for two days, presenting localized macular lesions eight hours after the administration of abiraterone. An oral desensitization protocol was carried out for ten days in which no hypersensitivity reactions were observed, thus achieving the successful administration of abiraterone.

Enzalutamide is a new potent inhibitor of the signaling pathway for the androgen receptor with a half-life of 5.8 days. It has been on the market for the treatment of metastatic castration-resistant prostate cancer since November 2013. We report a case of acute generalized exanthematous maculopapular rash induced by enzalutamide. In summary, newer androgen receptor blockers have a propensity to cause skin related adverse effects. Most common among these are apalutamide. Enzalumatamide, per se, is a safe drug and has not been associated frequently in causing maculopapular rash. Few cases has been reported. In all these cases, the drug was discontinued and 2nd line therapy was instituted. In this report, Enzalutamide was withheld for 10 days and anti-histaminics was instituted. After a full recovery, Enzalutamide was reinstituted in treatment. A 62-year-old male patient with no significant medical history, was diagnosed in March 2020 with metastatic prostatic adenocarcinoma. Baseline PSA was 456 ng/ml. PSMA PET scan showed evidence of multiple bony metastasis. He was started on Degarelix subcutaneous injection with oral abiraterone initially. PSA level showed initial decreasing trend till September 2021 followed by sudden increase. Intramuscular Injection leuprolide was started and initial responses were good followed by later rise of PSA from January. Tab Xtandi (Enzalutamide) was added to the regimen from 31.1.22. Three days after starting enzalutamide treatment, the patient experienced an acute skin reaction. It is about of the plaques covered with widespread millimetric non-follicular papules. Enzalutamide was stopped after appearance of rashes to avoid further serious adverse effects. Anti-histaminics were started. Complete resolution of skin lesions occurred within 10 days. Tab Enzalutamide was reinstituted on 11th day after stoppage and on complete resolution of skin resolutions. According to the CTCAE 5.0 criteria, these skin rash was graded as grade 2. In view of evidence in literature and clinical improvement after stoppage, the acute drug reaction was attributed to enzalutamide. Uro oncologist can be confronted with adverse skin drug reactions attributable to new therapeutic molecules. The slow resolution of symptoms seems be due to the long half-life of enzalutamide. It should not be withdrawn from therapy owing to these effects. Rather, it should be with stopped for 10-14 days. Basic treatment with anti-histaminics or topical steroids may be enough to warranty the resolution of symptoms, and the drug (Enzalutamide) can be continued thereafter.

Coronavirus disease 2019 (COVID-19) primarily affects the respiratory system but extrapulmonary manifestations, including the skin, have been well documented. However, transcriptomic profiles of skin lesions have not been performed thus far. Here, we present a single-cell RNA sequencing analysis in a patient with COVID-19 infection with a maculopapular skin rash while on treatment with the interleukin (IL)-12/IL-23 blocker ustekinumab for his underlying psoriasis. Results were compared with healthy controls and untreated psoriasis lesions. We found the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral entry receptors ACE2 and TMPRSS2 in keratinocytes of the patient with COVID-19, while ACE2 expression was low to undetectable in psoriasis lesions and healthy skin. Among all cell types, ACE2+ keratinocyte clusters showed the highest levels of transcriptomic dysregulation in COVID-19, expressing type 1-associated immune markers such as CXCL9 and CXCL10. In line with a generally type 1-skewed immune microenvironment, cytotoxic lymphocytes showed increased expression of the IFNG gene and other T-cell effector genes, while type 2, type 17, or type 22 T-cell activation was largely absent. Conversely, downregulation of several anti-inflammatory mediators was observed. This first transcriptomic description of a COVID-19-associated rash identifies ACE2+ keratinocytes displaying profound transcriptional changes, and inflammatory immune cells that might help to improve the understanding of SARS-CoV-2-associated skin conditions.
