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.

The importance of the ticks in medical field has been emphasized because of their association with and transmission of various diseases. We report herein a case of tick bite in a 55-year-old male farmer, who visited our hospital on July 2, 1981 with a parasite attached on right lower flank and rice to small pea sized, pruritic erythematous papular skin eruptions on chest and right lower flank. The skin lesions disappeared completely with.in five days after removal of the parasite, which was identified with an adult female tick which belongs to Genus Ixodes.

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.

Histopathologic findings of the tick bite are variable depending upon variable factors such as duration of feeding, size and shape of the mouthpart, type of tick secretion, etc. Intradermal cavity, which is formed as an uncoagulated blood pool under the inserted hypostome, is one of the characteristic acute histopathologic finding of tick bite especially by Ixodes species. We, herein, report a 46 year-old female patient of tick bile by Ixodes sp. in which histologic findings showed characteristic intradermal cavity formation surrounded by infiltration of many neutrophils and a few eosinophils as well as many extravasated red blood cells.

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.
