Generally speaking, as a direct microscopic examination of the falling debris, the small scales at the edge of the lesion are taken, placed on a glass slide, a little potassium hydroxide solution is dropped, the keratin is dissolved, and then placed under a microscope. By observing the hyphae of the fungus, the diagnosis can be confirmed. Of course, if conditions permit, a more definitive diagnosis can be made based on the culture of the fungus.
Diagnosis
Femoral diagnosis
diagnosis
It can often be diagnosed from clinical and mycological examinations.
Differential diagnosis
Should be differentiated from red sputum, seborrheic dermatitis, proliferative pemphigus, rubbing psoriasis.
Red sputum: A skin disease caused by a coryneform bacterium, commonly found in the underarms, thighs, etc. The skin of the lesion is brick red, with no inflammatory ring at the edges, no itching, and the direct microscopic examination of the fungus is negative.
Seborrheic dermatitis: Sometimes it can also invade the genital area, the rash is pale red plaque, there is desquamation, some are ring-shaped, the boundary is clear, but the direct microscopic fungus is negative.
Proliferative pemphigus is a benign type of pemphigus vulgaris. The skin lesions occur in the armpits, under the breasts, groin, vulva, around the anus, nasolabial folds and limbs. The damage was initially a thin-walled blisters with a positive Nissl sign. After smashing, papillary granulation is gradually proliferated on the erosion surface, and new blisters often appear on the edges, so that the damage area is gradually enlarged. Nie's sign is positive.
Psoriasis: Commonly known as psoriasis, it can invade the thigh, showing ring-shaped or plaque-like erythema. Generally, the surface has thick scaly, and other parts of the body can have the same rash.
