“…6 The clinical presentation of the cases in our investigation were very similar to those reported from Mysore in Karnataka and Jabalpur in Madhya Pradesh, though in those studies, species identification was not done. 7,8 Another investigation in Turkey, which too had similar clinical presentations had identified the organism as Paederus fuscipes. 9 In our study, the lower storeys of the buildings were relatively spared and only the 6 th to 16 th storeys were affected, showing that Paederus has a preference for higher storeys.…”

Paederus dermatitis is the skin irritation resulting from contact with the haemolymph of certain rove beetles, a group that is comprised by the genus Paederus. In May 2018, there was an increase in the number of residential students reporting with burning skin lesions. In this context, an outbreak investigation was conducted. A team of public health specialists visited these residential buildings and premises. The inmates who were affected were interviewed and examined. Suspected insects were collected and entomologically evaluated by the Zoological Survey of India. On examination of the affected individuals, it was observed that the rashes were very much suggestive of acid fly toxin induced lesions. Inspection of the premises, revealed small heaps of dried leaves with moisture at two sites which could have served as a suitable environment for acid fly multiplication. Our study concluded that Paederus fuscipes as the causative agent. Top storeys of buildings, illuminated at night, facing potentially wet areas were considered to be the potential risk factor. Fly proofing of the building, cleaning the institution premises and chemical treatment was suggested as appropriate control measures.

“…BBD can also mimick burns, phytophotodermatitis or cellulitis. 8 Eye involvement can occur due to direct contact or passive transfer of toxin. 9 The lesions usually subside in a week with exfoliation and residual pigmentation as seen in our study.…”

INTRODUCTIONBlister beetle dermatitis (BBD) is a seasonal irritant contact dermatitis caused mainly by beetles of the genus Paederus. It is clinically characterised by acute onset of linear erythematous plaques with vesiculation and crusting. These beetles breed in hot and humid conditions and maximum cases are seen during the months of May and June.1 In this study the various clinical patterns of blister beetle dermatitis observed in fifty four patients is described. METHODSFifty four patients with blister beetle dermatitis who presented to the dermatology outpatient department of Karuna Medical College during the months from May 2017 to July 2017 were included in this study. After taking consent, clinical details and photographs of the patients were taken. Patients were treated with topical corticosteroid and antibiotic combination. Systemic steroids were given for severe cases and oral antibiotics if the lesions were secondarily infected. Patients were called for review after one week. They were counselled about the methods to prevent future episodes of blister beetle dermatitis. RESULTSA total of fifty four patients were included in the study. Out of the 54 patients 35 were males and 19 were females. Age ranged from 8 to 46 years. Most of the patients had multiple lesions. Face was the commonest site involved (48%) followed by upper limb (33%). Lower limbs were least affected (Table 1). ABSTRACTBackground: Blister beetle dermatitis is an irritant dermatitis caused mainly by beetles of the genus Paederus. It is clinically characterised by acute onset of linear erythematous plaques mainly over exposed areas like face, neck and upper limb. Methods: Fifty four patients with blister beetle dermatitis who presented to the dermatology outpatient department over a period of three months from May 2017 to July 2017 were included in this study. The various clinical patterns of blister beetle dermatitis observed in these patients are described. Results: Face was the commonest site involved (48%) followed by upper limb (33%). Linear erythematous plaques with or without vesiculation were seen in 78% and kissing lesions were seen in 6 patients. Majority of patients (83%) had burning sensation at the site of the lesions and residual pigmentation was seen in 92% of patients. Conclusions: Blister beetle dermatitis is a common problem in tropical countries like India. Knowledge about the various clinical presentations will help in early diagnosis and treatment.

“…It is also known as dermatitis linearis, or paedrous dermatitis (PD). It is caused by chemical substances (Cantharidin, Pederin, Pseudopederin or Pederone), released from some beetles when crushed, pressed or come in contact with the skin [1][2][3]. The beetles do not bite or sting.…”
