Abstract Introduction: Eruptive cutaneous collagenoma is non familial connective tissue nevi of unknown etiology presented with an abrupt onset. To date, the literatures on eruptive cutaneous collagenoma are extremely rare in china. Here, we report two women with eruptive cutaneous collagenoma. Case present: Two women presented with multiple asymptomatic, skin-colored papules and nodules on the trunk and extremities with no systemic involvement. Histopathology revealed dense, coarse collagen fibers by hematoxylin-esoin stain and decreased, fragmented elastic fibers by Elastic stain compared with the normal skin. Basing on these findings, the diagnosis of eruptive cutaneous collagenoma was made. No specific treatment was given. Discussion: Eruptive cutaneous collagenoma is a very rare dermatosis that is often misdiagnosed as other connective tissue nevi. The pathogenesis is unclear, and also no efficient treatment is available. It is usually diagnosed based on clinical and histopathological findings. Conclusion: The present cases are relatively rare type of eruptive cutaneous collagenoma that provide more experience for clinician, and may be helpful for them to make correct diagnosis for suspicious cases.

Objectives: The wide use of antibiotics for acne is the main cause of drug-resistantCutibacterium acnes. However, the complete genetic sequence reference of C. acnes has not yet been reported. Herein, we report the complete genetic sequence of Cutibacterium acnes type strain ATCC6919. Methods: Whole-genome sequencing of Cutibacterium acnes ATCC6919 was performed using both the Illumina Hiseq4000 and PacBio RSII single-molecule real-time sequencing platforms. The generated sequence reads were de novo assembled using the HGAP3 protocol of single-molecule real-time analysis v.2.3.0 software. The draft genome was annotated and further analyzed by various bioinformatics tools. Results: The total genome length of Cutibacterium acnes ATCC6919 was 2,495,001bp (60.02% G + C content), with 2,450 coding sequences including 2,358 proteins, 45 tRNAs, 9 rRNAs, and 1 sRNA. The Comprehensive Antibiotic Resistance Database showed that the gene (thy A) found in ATCC6919 was associated with resistance to aminosalicylic acid. Antimicrobial susceptibility testing showed that this isolate was not sensitive to metronidazole and sulfamethoxazole, but was sensitive to all other tested antimicrobials (erythromycin, azithromycin, clarithromycin, tetracycline, minocycline, trimethoprim, levofloxacin, ceftriaxone, and doxycycline). Conclusion: This study reports the complete genome sequence of Cutibacterium acnes ATCC6919, which provides a valuable reference for comparative analysis based on the genomic characteristics and resistance gene diversity of Cutibacterium acnes.

The 2019 novel coronavirus infection has brought a great challenge in prevention and control of the national epidemic of coronavirus disease 2019 (COVID-19) in China. During the fight against the epidemic of COVID-19, properly carrying out pre-examination and triage for patients with skin lesions and fever has been a practical problem encountered in hospitals for skin diseases as well as clinics of dermatology in general hospitals. Considering that certain skin diseases may have symptom of fever, and some of the carriers of 2019 novel coronavirus and patients with COVID-19 at their early stage may do not present any symptoms of COVID-19, to properly deal with the visitors to clinics of dermatology, the Chinese Society of Dermatology organized experts to formulate the principles and procedures for pre-examination and triage of visitors to clinics of dermatology during the epidemic of COVID-19.
