Even with obvious causes, the specific allergen might not be known, and ACD to other chemicals may be associated. Seborrheic dermatitis (SD) is one of the most common dermatoses of infancy. Additionally, we discuss epidemiology, etiology, diagnosis, differential diagnosis, and treatment modalities for SD, as well as an association of SD and AD. However, AD is a more likely diagnosis for scalp hyperkeratosis, but it is not impossible to see SD in prepubertal children.27 In most instances, the diagnosis of SD is clinically obvious.
Irritant dermatitis, atopic hand dermatitis and contact hand dermatitis account for at least 70 of all diagnoses.

In the next stage, the skin lesions transform into obvious vesicles and papules that are likely to occur in groups. The diagnosis can be confirmed by a simple blood test for IgA antibodies against tissue transglutaminase (which cross-react with epidermal transglutaminase), 18 and by a skin biopsy in which the pattern of IgA deposits in the dermal papillae, revealed by direct immunofluorescence, distinguishes it from linear IgA bullous dermatosis 9 and other forms of dermatitis. Jean-Paul Marat: The differential diagnosis of his skin disease. The incidence of rhinophyma, the most obvious stigma of rosacea, is unknown and occurs more often in men. Seborrheic dermatitis has similar skin manifestations but with a distinctive distribution pattern at the scalp, eyebrows, and nasolabial folds. The differential diagnosis for rosacea is listed in Table 3. Are there any obvious factors that either trigger or relieve the problem? How could you think about the differential diagnosis?! 33.
