Red spot on glans

Introduction The glans red dot is one of the main symptoms of balanitis, and the inflammation of the glans mucosa is called balanitis. The disease can be caused by various pathogen infections, local irritation and other factors. Divided into acute superficial balanitis, Candida balanitis, trichomonas balanitis.

Cause

It is caused by acute and chronic inflammation caused by various reasons, such as excessive prepuce, trauma, local physical factors and infection factors.

Skin smear microscopy

1, check the test: Candida balanitis (the dermatitis) can be found in the lesions of the glans, foreskin microscopic examination or culture can be found Candida. Trichomonas balanitis can find trichomoniasis on secretions.

2, direct microscopic examination: scrape the surface scale of the glans glans, coronary sulcus or foreskin as the specimen to be examined. The specimen to be inspected was prepared by using 10% potassium hydroxide or physiological saline. Microscopic spores and pseudohyphae were observed under the microscope. If more pseudohyphae were found, it indicated that Candida was in the pathogenic stage.

3, staining examination: Gram staining, Congo red staining or PAS staining after microscopic examination, the positive rate is higher than direct microscopy. Gram staining, spores and pseudohyphae dyed in blue: Congo red and PAS staining, spores and pseudohyphae dyed red.

4. Separation and culture: Candida culture can be performed on patients with negative smear test. The test specimens were inoculated on Sabouraud medium under aseptic conditions. When inoculation, the test tube culture medium was cut obliquely, and each tube was inoculated with 2-3 spots, and each sample was inoculated with 2 tubes. The medium was incubated in a 37 ° C incubator for 24-48 hours, and a large number of milky white colonies were observed. A small number of colony smears were picked with the inoculation needle, and microscopic examination or microscopic examination was performed. A large number of spores were observed. Diagnosed as a Candida infection.

5, Candida antibody test: Candida albicans antibody can be detected by immuno-double expansion method or latex coagulation method.

Differential diagnosis

Balanitis needs to be differentiated from glans:

First, balanitis

1, ring-frozen foreskin balanitis on the glans and foreskin, visible erythema, gradually enlarged, ring-shaped, can form a superficial ulcer surface.

2, acute superficial foreskin balanitis at the beginning of local redness, the skin of the penis is red, swollen, consciously the glans have a burning and itching feeling.

3, Trichomonas foreskin balanitis glans from the papules and erythema, gradually enlarged, the edge is clear, small spots on the erythema can be seen, the formation of erosion surface.

Second, glans herpes

1. Genital herpes is a sexually transmitted disease. Most patients have had high-risk sexual behaviors in the near future. In addition, the disease can be transmitted through contact and the patient cannot ignore it.

2, early symptoms have local itching, burning pain, the emergence of blisters of varying sizes, formed a superficial ulcer after rupture, about 7 to 10 days to dry to form scars.

3, the patient also has general malaise, low fever, headache and inguinal lymphadenopathy. Later genital herpes virus can invade the urethra, bladder, frequent urination, dysuria, and even urinary retention.
