Scabies causes severe itching, particularly at night, when there are fewer distractions. The eruption is characterized by small, 2- to 5-mm red papules that are predominantly discovered in intertriginous or warm and protected areas like the finger webs, inframammary areas, and axillae. It's caused by the mite, Sarcoptes scabiei.
The pathognomonic lesion is the burrow, a brownish, irregular line with scaling at one finish and sometimes a vesicle at the other finish. Regrettably, the burrow is often hard to find. An additional typical site will be the penis. Lesions may also seem on the trunk and extremities, but rarely on the face except in kids or in immunocompromised patients. The papules sometimes are eczematized and secondarily infected as the result of scratching to alleviate the marked nocturnal itching.
The presentation of scabies can vary. Infants and also the elderly can have red papules scattered more than the entire physique. Crusted scabies represents a severe infestation that occurs in immunocompromised patients. Scabies incognito happens when the patient has been applying topical corticosteroids, which impede the inflammatory process but still allow the mites to proliferate.
Scabies can be confused with folliculitis and neurodermatitis. Other arthropod bites can look like scabies, but penile lesions confirm the presence of scabies. Canine scabies produces clusters of red papules, usually on the abdomen, but no mites are discovered on the human skin. Crusted scabies could be confused with eczematous conditions or psoriasis.
A recent lesion is scraped, the material is treated with 10% potassium hydroxide solution to dissolve the keratin, and also the specimen is studied beneath light microscopy. The mite measures 0.4 - 0.3 mm in females and 0.2- 0.15 mm in males. Confirmation may be challenging to obtain if the patient has washed conscientiously with soap.
Permethrin cream 5% is applied from the neck to the toes for 12 hours before washing it off. A second choice is lindane lotion 1%, applied from the neck to the toes for a 12-hour period before washing it off. Lindane should not be utilized in infants or in pregnant women. Ivermectin, 200 microg/kg given once, is utilized as an oral treatment in some countries.
To stop undertreatment or recurrence, topical treatments must be applied to all areas including in the umbilicus and beneath the fingernails. Symptomatic relief is given with high-potent to super-potent topical corticosteroid ointment or cream. Pruritus can persist even weeks beyond effective therapy. Treatment should be given to close contacts and family members.
When the application of cream or lotion is inadequate, the condition persists.
