This study suggests that eruptive vellus hair cysts often have atypical pathological changes and likely originate from the infrainfundibulum and sebaceous duct based on keratin expression analysis.

This study found that anti-TNF therapy-induced alopecia exhibits distinct clinical and histopathological features and can mimic psoriatic alopecia and alopecia areata, with some patients improving with topical treatment.

This case study in an 8-month-old mixed-breed dog with symptoms and histopathological findings supports a diagnosis of hereditary junctional epidermolysis bullosa, although specific genetic mutations weren't identified.

In this case study, a patient developed a rash consistent with acute generalized exanthematous pustulosis after increasing the dose of semaglutide, suggesting that the reaction was likely due to the excipient propylene glycol, highlighting the importance of ingredient analysis and multidisciplinary collaboration for patient safety.

This study in Kitui County, Kenya, identified histopathological lesions due to Cordylobia anthropophaga infestations in dogs, including parasitic granulomas and eosinophilic lymphadenitis, leading to severe health effects such as emaciation and potential death.

This study observed that dermoscopic features of skin affected by topical corticosteroids and hydroquinone correlated with histopathological changes, highlighting the importance of awareness regarding their long-term adverse effects.
