When eczema-like changes appear on the skin of the scrotum, perineum and other apocrine-rich areas, you should think of the possibility of dog and cat scrotumitis. Although it is not dangerous, it is very troublesome. The initial stage is a small blister-like rash or scaly erythema with clear borders. After scratching, the surface is eroded, exuded, and crusted. After the scabs fall off, the skin is verrucous hyperplasia, and gradually infiltrates outward, forming rough skin lesions with alternate erosions and erythema, often with a disgusting odor due to secondary infection.

2. The papular type begins with several scattered soy-sized papules on the side of the scrotum, which are significantly higher than the skin, flat, covered with thin brown scabs, and later increase and expand, and are densely and symmetrically distributed in the scrotum Both sides of the suture, about 3 × 4 cm, are fused into pieces, often fused at the root of the scrotum. There are irregular, gray-black thick scabs significantly higher than the skin surface at the coronal groove of the penis, and gray scales on the penis. Scattered folliculitis or abscesses on the pubic and groin area.

3. White papules and psoriasis type This type is rare, but very typical. A large area in front of the scrotum is formed by the fusion of flat papules the size of melon seeds, with silvery white, and silvery white scales fall off when scratched.
