The pathology related to a tick bite reaction is well described. Formation of a cavity below the mouthparts of the tick and mixed dense cellular dermal infiltration are general histopathologic findings of a tick bite. In addition, granuloma formation, vasculitic response, and panniculitis were reported. We present two cases of tick bite showing a new histopathologic finding, a localized fat herniation response.

We report herein an unusual case of tick bite. A 56 year old woman complained of erythematous nodular skin lesion on the left upper chest. An excision biopsy specimen of the lesion showed darkish-red nodule, in which there was a tick. It was identified as an adult female of Ixodes nipponensis by the scanning electron microscopic examination.

A 53-year-old woman presented with asymptomatic pedunculated mass on her buttock. She was attacked by the tick while climbing the Jungbyung mountain located in Changwon City, the southern coastal area of the Korean Peninsula. It was identified as male Amblyomma testudinarium according to its morphological characteristics. Histological examination showed dense inflammatory infiltration of neutrophils and eosinophils, and dilated vessels on the dermis beneath the biting site of the tick. There have been only few reports of the tick bite by A. testudinarium in the Korean literature. To the best of our knowledge, our patient is the second case of tick bite from this species and the first tick bite from the male tick recorded in Korea. Here, we report a case of tick bite by male A. testudinarium in a woman, including a review of relevant literature.

Since 1982, 31 cases of tick bites were reported in Korea and only one case of Haemaphysalis longicornis related to tick bites was included. Until now, nymph related or multiple tick(more than three) related to tick bites were not reported in the Korean literatures. We report three cases of tick bites by Haemaphysalis longicornis. The first case is a 71-year-old Korean woman who had a tick stuck on the anterior chest area. The second case is a 64-year-old Korean man who visited a clinic for pruritic, multiple, erythematous papules and nodules. The third case is 50-year-old man who visited the hospital for pruritic, erythematous nodules on calf area. Eight ticks were collected from three patients which were one female in the first case, two females in the second case and two females and three nymphs in the third case and all of them were identified as Haemaphysalis longicornis.

Tick bites are dermatoses not commonly encountered in Korea. Identification of causative ticks as well as recognition of clinical signs and histopathologic findings are important in making a diagnosis in tick-related dermatoses. Hard ticks which belong to the Family Ixodidae are responsible for most tick-related diseases. Since the first human case of tick bite in Korea was reported in 1982, seventeen cases have been reported up to the present. All the inflicted ticks belonged to the genus Ixodes except a case by Haemaphysalis flava. Among 16 ticks, collected from 16 cases of tick bites caused by the genus Ixodes, nine I. nipponenses, an I. ovatus and I. persulcatus were identified. Recently we experienced 8 cases of tick bites, 6 of them were caused by the genus Ixodes including 4 I. nipponenses. One of them, whose essential complaint was fever and chills, showed the clinical course of tick bite pyrexia which had not been reported in Korea. The clinical and epidemiological findings of tick bites reported in Korea were reviewed, including these 8 cases.

We report a case of tick bite caused by Haemaphysalis flava which have never been reported in Korean medical literature. An 31-year-old woman had a asymptomatic erythematous indurated plaque with central crust by tick bite on the left upper back. A excisional biopsy specimen from the skin lesion showed eosinophilic degeneration with thrombosed blood vessels and dense inflammatory cells infiltration mainly composed of eosinophils in the reticular dermis. We could identify this causative tick as Hamaphysalis flava by using the scanning electron microscopic examination.
