![]() Ticks are obligate blood-sucking arthropods that parasitize every class of vertebrate in almost every region of the world. ![]() Several of the organisms were removed with forceps and visualized in mineral oil under the microscope they were rotund, 6-legged organisms ( Figure 3). Under magnification, these were determined to be bugs of unknown type whose heads were partially burrowed under the skin ( Figure 2). On close inspection, we found dark, 1-mm organisms in the center of many of the papules. In the clinic, we found hundreds of red, blanching papules and papulovesicles on her trunk and extremities, especially in areas that had been under her clothing. She presented to our dermatology clinic for further recommendations before using the permethrin cream. Despite numerous showers and scrubs, the rash progressed, and the patient began to note the presence of tiny dark “bugs” attached to her skin in the centers of many of the papules. ![]() She visited several physicians in the following days who variously diagnosed infestations with “no-see-ums” (for which she was prescribed cetirizine hydrochloride and a 5-day course of prednisone), bedbugs, and finally pubic lice (for which she was given a prescription of 5% permethrin cream). Multiple erythematous papules on a 51-year-old woman seen 5 days after her exposure to wooded area. 2 - 5 The present report summarizes the characteristic clinical and diagnostic features of infestation by larvae of Amblyomma species and may help clinicians make similar diagnoses in the future. In addition to being vectors for human diseases, ticks can cause several primary dermatologic manifestations including erythematous papules, skin hemorrhages, papular urticaria, diffuse dermatitis, necrotic ulcers, prurigo, erythema migrans–like rash, and patchy alopecia, but reports of primary infestations are rare. 1 In particular, Amblyomma species have been identified as the vector for several human diseases including Rocky Mountain spotted fever, Q fever, ehrlichiosis, tularemia, and African tick bite fever via salivary secretions. ![]() 1 Their role in the transmission of several human infectious diseases has been known since the beginning of the 20th century. Ticks have been recognized as human parasites for thousands of years and are the second most common vector of human infectious disease after mosquitos. We present a case of a healthy 51-year-old woman who was bitten by multiple larvae of the tick, Amblyomma species, most likely A americanum or the lone star tick. Patients with multiple pruritic papules that appear to be bites present a challenge to the clinician. Recognition of lone star tick larvae as a cause of multiple bites may be helpful in similar cases. The patient described herein had an unusually large number of pruritic papules as well as tick larvae present on her skin. The organism was later identified as the larva of Amblyomma species, the lone star tick.Ĭonclusions Multiple pruritic papules can pose a diagnostic challenge. She was treated with permethrin cream and the lesions resolved over the following 3 weeks without sequelae. Observation We describe a 51-year-old healthy woman who presented to our clinic with multiple erythematous papules and partially burrowed organisms 5 days after exposure to a wooded area in southern Kentucky. The presence of multiple lesions and partially burrowed 6-legged tick larvae can present a diagnostic challenge for clinicians. Infestation by the larvae of ticks is not commonly recognized, with only 3 cases reported in the literature. In addition to their role as vectors, ticks and their larvae can also produce primary skin manifestations.
