Insect Bites and Stings*

Most insects have a stinging apparatus at the tail end of their abdominal segment and can deliver venom. The venom can usually result in pain, erythema, abscess, or allergic reaction in human tissues such as the skin and even the lips. The presentation of lip abscess, especially in the vermilion, is rare and needs to be appropriately managed. A 39-year-old prediabetic male presented with a swollen right lower lip stung by an insect six days before the consult. The swelling started as a vesicle which became bigger, then burst, exuding a yellowish fluid and blood. The swollen area became more significant, and pain was felt. The clinical presentation was that of a lower lip abscess. Adequate antibiotics were prescribed along with a corticosteroid and a topical antiseptic. The treatment was essential to prevent the dissemination of infection and the likelihood of tissue necrosis. This case report is presented as a rare clinical case of a lower lip abscess due to an insect sting with spontaneous drainage after treatment in a prediabetic male. The dentist and clinician needed to identify this condition and to manage the case properly.
Insect Bites and Stings

Reactions to Hymenoptera insect stings are common. While most are self-limited, some induce systemic allergic reactions or anaphylaxis. Prompt recognition, diagnosis, and treatment of these reactions are important for improving quality-of-life and reducing the risk of future sting reactions. This review summarizes the current recommendations to diagnose and treat Hymenoptera sting induced allergic reactions and highlights considerations for various populations throughout the world.

Ants(Family Formicidae) are very successful organisms occuring in trernendous numbers worldwide in terrestrial habitats. All ant species may bite, and on species sting. 48 species in 26 genus have been reported in Korea, but only systemic reaction induced by the anti Brachyponera chinersis, has been reported in the Korea terature. A 48 year old man was stung on the neck, abdomen, and dorsum of the hand by flying stinging ants. He experienced moderate pain, burning and itching sensation. Clinical course and histopathologic findings of the lesions caused by the stinging ant was observed without specific treatment. The stinging ants collected from t,he patient.s skin and his house were identified as Euponera chosensis belonging to Subfamily Ponerinae. To the best of our know ledge, this is the first clinical repor of the insect sting by Euponera chosensis in the Korean literature.

Actinic granuloma is a specific disease entity characterized by clinical lesions indistinguishable from granuloma annulare, but occuring on solar damageci skin. Ilistologically, elastic tissues are destroyed by the granulomatous process in actinic granuloma, but not, in granuloma anriulare. We report two cases of actinic granuloma with each diagnosed as a giant cell and sarcoirlal variant of the disease. Interestingly, one case developed on the non sun-exposed skin and anothr case related to the history of an insect bite.

Granuloma annulare (GA) is a benign granulomatous disease. Although its etiology is not well understood, there are some reports about GA occurring after specific conditions such as sunburn, a tuberculin test, insect bites, viral diseases and trauma. Especially, in case of the auricular region which is vulnerable to trauma, it seems that GA has some relation with trauma. In 1992, Mills and Chetty proposed that repetitive minor trauma may be an important cause of auricular GA. Among the 5 cases of auricular GA that have been reported in the English literatures, 3 cases are assumed to be associated with repetitive minor trauma. Herein, we report on two cases of auricular GA that were thought to be associated with repetitive minor trauma.

The purpose of this study was to elucidate the prevalence rate of tbe concomitant; atopic diseases in the patients with allergic rhinitis and, concurrently, the incidence of the atopic diseases in the families of the patients. A total of 40 patients who were referred to the department of dermatology, Kang Nam St. Marys Hospital, for the confirmative examinations of allergic srhiniti were taken for this study. The results were as follows, 1. The prevalence rate of concomitant atopic dermatitis in the sample patients was 22.5% and that of concomitant bronchial asthma was 12. 5% The prevalence rate of concomitancy with both diseases was 2.5% and that of concomitancy with atopic dermatitis and/or bronchial asthma was 37.5%. 2. The frequency of the associated manifestations, in descending order, was allergic conjunctivitis (30%), urticaria or angioedema (25%), insect sting (22.5%), oral symptoms (5%), migrane or headache (5%), immediate drug reactions (2.5%) and gastrointestinal symptoms (2.5%).

A 25 year old man presinted with erythematous and inderated plaques on the upper and lower extermities that were preceded by insect bites while traveling in central Africa. The patient had a past histrory of Kimura's disease, asthma, and allergic rhinitis, Histologic examination revealed panniculitls showing massive eosinophilic infiltration. The dermis showed eosinopbilic infilreatiom without flame figyres. The patient responded well to oral conrticosteroids. This patient did not fit the diagnosis of eosinoplilic pannicylitis, eosinophilic cellylitis, hypereosinophilic syndrome or eosinophilic vascylitis.

Myiasis is defined as an infestation of live human and vertebrate animals with dipterous larvae, which at least for a period, feed on dead or living tissue of the host, liquid body substances or ingested food. Among several types of myiasis, cutaneous myiasis is classified as the most common type. Cutaneous myiasis is subdivided into furuncular, migratory and wound myiasis based on the infested morphology. Common dipterous larvae for furuncular myiasis include Dermatobia hominis, Cordylobia anthropophaga, Cuterebra spp., Wohlfahrtia vigil and W. opaca. Early lesions resemble other insect bite reactions, but the physician can differentiate the lesions by the visualization of larvae through an aperture with serous exudes as the larvae grow. Although cutaneous myiasis is not uncommon in endemic areas, there has been one previous report of cutaneous myiasis by C. anthropophaga in the Korean dermatological literature. We report here an interesting case of furuncular cutaneous myiasis by C. anthropophaga in a patient after traveling to Cameroon.
