Rowell\'s syndrome is an autoimmune disease characterized by lupus erythematosus, erythema multiforme skin lesions, and speckled antinuclear antibody. We report the case of a woman who presented with erythema multiforme with target-type skin lesions and vulvar vegetation who fulfilled the criteria for Rowell\'s syndrome and condyloma acuminatum. The simultaneous occurrence of both conditions has rarely been reported in the literature.

OBJECTIVE: This review aims to summarize the latest application of optical coherence tomography (OCT) in oral mucosal diseases, promoting an accurate and earlier diagnosis of such disorders, which are difficult to be differentiated.
UNASSIGNED: References on the application of OCT in oral mucosal diseases were mainly obtained from PubMed, Embase, Web of Science and Scopus databases, using the keywords: \"optical coherence tomography and \'oral mucosa/oral cancers/oral potentially malignant diseases/oral lichen planus/oral leukoplakia/oral erythroplakia/discoid lupus erythematosus/oral autoimmune bullous diseases/oral ulcers/erythema multiforme/oral mucositis\'\".
RESULTS: It is found that OCT is showing a promising application potential in the early detection, diagnosis, differential diagnosis, monitoring of oral cancer and oral dysplastic lesions, as well as the delineation of tumor margins. OCT is also playing an increasingly important role in the diagnosis of oral potentially malignant disorders, oral mucosal bullous diseases, oral ulcerative diseases, erythema multiforme, and the early detection of oral mucositis.
CONCLUSIONS: Optical coherence tomography, as a novel optical technique featured by real-time, noninvasive, dynamic and high-resolution imaging, is of great use to serve as an adjunct tool for the diagnosis, differential diagnosis, monitoring and therapy evaluation of oral mucosal diseases.

BACKGROUND: Dermatologic toxicity has been reported as the most common immune-related side effect of programmed cell death 1 inhibitors. Previous reports related to Sintilimab include rash, pruritus, vitiligo, Stevens-Johnson syndrome, toxic epidermal necrolysis, and so on.
METHODS: A 66-year-old man was treated with Sintilimab as monotherapy for sigmoid colon cancer. After the second prescription, he developed a more severe and widespread rash.
METHODS: The diagnose of erythema multiforme drug eruption induced by Sintilimab was considered.
METHODS: The patient received intravenous and oral methylprednisolone, routine antihistamines and topical gluccorticoids.
RESULTS: The patient\'s symptoms were gradually relieved during hospitalization and was discharged following resolution of symptoms. He refused to continue using Sintilimab.
CONCLUSIONS: This is the first reported case of Sintilimab-induced erythema multiforme drug eruption. It is advisable to inform patients of potential dermatologic toxicity that may occur after using immune checkpoint inhibitors, so that we may prevent the further development of it and avoid the discontinuation of immune checkpoint inhibitors.

Background: Limited data exists on the use of rivaroxaban for the treatment of pediatric patients. This report presents a case of probable rivaroxaban-induced Erythema Multiforme in Children. Case Summary: A female patient aged 5.5 years with antiphospholipid syndrome (APS) was administered oral rivaroxaban tablets 2.5 mg twice a day for 16 days. Subsequently, the patient developed a slight itching sensation on both feet and buttocks without an apparent cause. The following day, erythema multiforme appeared across the body in a scattered pattern. The erythema presented higher than the skin surface and partially merged into areas of the skin. Following an increase in the extent and degree of the erythema, all oral medications were ceased. Treatment with dexamethasone sodium phosphate injection, mometasone furoate cream, and mucopolysaccharide polysulfate cream resulted in an improvement of erythema multiforme. The erythema diminished and did not deteriorate subsequent to changing from rivaroxaban tablets to warfarin sodium tablets, and receiving nadroparin calcium injection.

Rowell syndrome (RS) is an uncommon condition characterized by erythema multiforme (EM)-like lesions and lupus erythematosus. It is more common in females, and EM may be the first manifestation of the disease with positive autoantibodies, such as antinuclear antibody (ANA), SSA, SSB and rheumatoid factor. The pathogenesis of RS is unknown and is likely caused by drug induction, ultraviolet exposure and infection.
We describe a case of RS from China which presented as characteristic targetoid-like lesions and chilblain-like erythema on hands and feet. This is a case of RS in a female patient from the inpatient department of dermatology.
A 41-year-old female with systemic lupus erythematosus exhibited chilblain-like erythema and characteristic EM lesions on her extremities. She tested positive for serum ANA (1:320) and anti-double-stranded DNA, as well as other autoantibodies. Systemic glucocorticoids and hydroxychloroquine worked effectively for her.
The present case met diagnostic criteria of RS. Notably, there was a co-occurrence of facial butterfly erythema, chilblain-like erythema and EM lesions distributed on the limbs in this case.

BACKGROUND: Epstein-Barr virus (EBV) infection is associated with a variety of diseases and can involve multiple organs and systems, with complex and nonspecific clinical manifestations that are easily misdiagnosed. Chronic EBV infection with persistent erythema multiforme (EM) on the cheek as the main manifestation is very rare and has been reported rarely.
METHODS: This article reports a case of an adolescent female with chronic EBV infection who presented with chronic symmetrical erythema lesions on the face for 4 years, exacerbated with photophobia, lacrimation, Henoch-Schonlein purpura (HSP)-like rash, decline in granulocyte and erythrocyte lineages, hematuria, and proteinuria for 1 week.
METHODS: The disease was initially misdiagnosed as systemic lupus erythematosus (SLE) and later confirmed as chronic EBV infection by skin biopsy. In the case, EBV infection not only caused chronic facial EM, but also induced acute HSP and purpura nephritis (hematuria and proteinuria type).
METHODS: The child was treated with 1 week of glucocorticosteroids in adequate doses combined with acyclovir antiviral therapy and 3 sessions of hemoperfusion. After discharge, she took prednisone acetate (15 mg twice a day) orally for 1 month and then discontinued.
RESULTS: She was discharged with her rash relieved and normal blood routine test and urine routine test. After 13 months of long-term follow-up, her facial erythema and hyperpigmentation became lighter, and there was no new rash on the whole body, and no abnormality in continuous monitoring of complete blood count and urine test.
CONCLUSIONS: This case suggests the need to be alert for chronic EBV infection in adolescent females with chronic facial EM rash and multiple organs and systems injury, in addition to connective tissue diseases such as SLE.

BACKGROUND: 5-Fluorouracil (5-FU) and actinomycin D (ActD) are often used in chemotherapy for various cancers. Side effects are more common in bone marrow suppression, liver function impairment, and gastrointestinal responses. Skin effects are rare and easy to be ignored by doctors and patients, which can lead to life-threatening consequence.
METHODS: We reported a 45-year-old woman patient developed skin erythema and fingernail belt in chemotherapy of 5-FU and ActD.
METHODS: Erythema multiforme drug eruption.
METHODS: Laboratory tests including blood and urine routine, liver and kidney function, electrolytes and coagulation function and close observation.
RESULTS: The rash was gone and the nail change returned.
CONCLUSIONS: Delays in diagnosis or treatment may lead to serious consequence. We should pay attention to the dosage of 5-FU and ActD, monitor adverse reactions strictly, to reduce occurrence of skin malignant events.

Erythema multiforme is a widespread hypersensitivity reaction, its pathogenesis is related to a variety of factors, including drugs and viral and bacterial infections. It is true that erythema multiforme is often caused by viruses while current studies suggest that it is mostly associated with herpes simplex virus infection, rarely associated with varicella-zoster virus infection. Here, we report a 50-year-old man admitted to our hospital because of rashes on the left rib with pain for 9 days and on limbs and hands for 2 days. Laboratory data showed that varicella-zoster virus (VZV-DNA) test was negative in blood by qualitative polymerase chain reaction. Herpes zoster virus IgM (VZV-IgM) enzyme linked immune sorbent assay was negative, and herpes zoster virus IgG (VZV-IgG) enzyme linked immune sorbent assay was positive. Herpes zoster and erythema multiforme was diagnosed. After treatment with antiviral, antiallergic, and topical drugs, the rashes was significantly improved. Our case report contributes to the pathogenesis of erythema multiforme.
