This study found that a simplified classification based on clinical and morphological features may aid in the diagnosis and initial management of inherited keratinizing disorders, although genetic analysis is essential for definitive diagnosis.

This study found that polymorphic eruption was the most common pregnancy-related dermatosis, occurring mostly in the third trimester.

This study suggests that using a dermoscope, a handheld microscope, can effectively help distinguish between Pityrosporum folliculitis and Acne vulgaris by revealing unique lesion characteristics that are not visible to the naked eye, offering a practical diagnostic alternative when KOH examinations are unavailable.
