A 5-year-old Chinese girl presented to a dermatology clinic with itching and eyelash loss on her left lower eyelid. She had recently traveled to Jeju Island, South Korea, and had contact with rabbits and cats. Trichoscopy revealed pustules, scales, broken eyelashes, and microscopic examination confirmed the presence of Trichophyton interdigitale. The diagnosis was tinea blepharitis, and the symptoms resolved after treatment with oral itraconazole and topical fluconazole eyedrops. Blepharitis is an inflammatory condition of the eyelid margin that can have various causes, including infections and environmental factors. Trichoscopy provided valuable diagnostic information in this case. Treatment for blepharitis depends on the type and pathogens involved. Tinea blepharitis is a rare dermatophyte infection that can be easily overlooked. [Extracted from the article]

The choice of ultrasound frequency depends on the condition of the lesions and the specific observation requirements. Ultrasound frequency ≥ 70 MHz would be more appropriate for small superficial basal cell carcinomas. [ABSTRACT FROM AUTHOR]

The article describes a case of a 28-year-old female who developed rashes and intermittent fever after camping and gathering mushrooms in a wooded area. It is reported that the patient presented with enlarged lymph nodes, an eschar with an erythematous halo, and multiple erythematous maculae on the trunk and limbs.

One side of the transparent film is adhesive, thus it can be used to cover the glass window and wrap the metal ring and the front of probe (Fig. Contamination and crossinfection are always a significant concern when using reflectance confocal microscopy in the clinic because the glass window and metal ring at the front of the probe must contact the skin and mucosal surfaces, and sterilization of the imaging probes is usually impossible.

We report the use of a marking pen with metallic ink to assist body surface location in reflectance confocal microscopy (RCM). For other techniques, lesions can be marked out on the skin with conventional surgical marking pens, but this type of ink cannot be detected by RCM. [Extracted from the article]
