Patients with anxiety or depression, a common occurrence, should have these psychological issues addressed. Treatment consists of the identification and elimination of any underlying pruritic condition such as folliculitis that initiates the picking. The best approach is to avoid the possibility of chigger bites through the use of standard insect repellents. Oral antihistamines and topical steroids provide some symptomatic improvement. Lesions due to chigger bites resolve spontaneously in about 2 weeks.
CHERRY ANGIOMA TINY PINPOINT RED DOTS ON SKIN SKIN
The skin such as at waistband and inguinal folds. Such bites are particularly likely to occur where clothing binds against However, those patients who are allergic to chigger proteins develop extremely pruritic, pink, nonscaling, dome-shaped 0.5- to 1.5-cm papules, occasionally with a central vesicle ( Fig.
In nonsensitized people, chigger bites are tiny red papules that are minimally symptomatic and resolve quickly. Chiggers, also called harvest mites, bite and fall off rather than burrowing into the skin as occurs with the scabies mite. The most common of these bites are due to chiggers. However, such bites do occur in campers and hikers who expose the genital area when urinating, defecating, or having intercourse alfresco. Insect bites in the genital area are uncommon because this area is usually protected by clothing. Note, however, that this is not a hard and fast distinction since some of the conditions discussed may present with a mixture of papules and nodules. The lesions in the first part of this chapter represent the smaller lesions (the red papules) and those in latter part represent the larger lesions (the red nodules). Therefore, when encountering pink or red papules or nodules, the clinician may also need to consider lesions from Chapter 5. This is particularly notable in patients with a light complexion. Many skin-colored papules and nodules appear pink or red at times because of secondary inflammation or increased vascularity. Most of the lesions considered in this chapter lack scale and therefore are smooth surfaced. Inflammatory papules and nodules are most often medium to dark red toward the center and fade to light red or pink at their less distinctly marginated borders. Nonvascular neoplasms are also sharply marginated but tend to be lighter red in color. Vascular neoplasms present as bright red, dusky red, or violaceous papules and nodules with sharply demarcated borders. Genital disorders that present as red papules or nodules are most often either neoplasms or inflammatory lesions.
