Alert on Imported Fungal Infection: The First Report of Tinea Capitis Due to in China.

We report cases of infections on the scalp of three individuals from an African family, originating from Mali and residing in Guangzhou. This is the first time that has been reported in China. The index case involved a 2-year-old boy who presented with scalp patches and scaling for more than 1 year.

Detection of superficial lymphatic malformation with dermoscopy and reflectance confocal microscopy.

Background: Superficial lymphatic malformation (SLM) is a congenital disorder of the lymphatic channels. It usually appears as clusters of vesicles filled with lymphatic fluid and blood on the skin that resemble frogspawn, making it difficult to distinguish from haemangiomas, angiokeratomas, and pyogenic granulomas. Although pathological results have diagnostic values, the significance of noninvasive examination in the diagnosis and differential diagnosis is also worth exploring.

ERBB1/2/3 Expression, Prognosis, and Immune Infiltration in Cutaneous Melanoma.

Background: The four ERBB tyrosine kinase family members [ERBB1 (epidermal growth factor receptor, EGFR), ERBB2 (HER2), ERBB3 (HER3), and ERBB4 (HER4)] (ERBB receptor family) have been shown, according to previous studies, to be related to the cutaneous melanoma. ERBB3 is the only member of the ERBBs that lacks tyrosine kinase activity and thus needs to dimer with other tyrosine kinases receptors to trigger the signaling pathway, while ERBB3 may dimer with all members of the ERBB family. Melanoma progression depends on activation of ERBB signaling, especially the ERBB3/ERBB2 cascade.
