ABSTRACT
The aim of the present study was to determine the Hepatitis B Virus (HBV), Hepatitis C Virus (HCV), and diabetes mellitus (DM) frequencies in lichen planus (LP) cases in our region. We performed a retrospective review of records from all cases that were diagnosed with LP at the our department between 1997 and 2002. The results were compared with the control group (any type of dermatosis other than LP). The 260 LP cases included 108 (41.5%) males and 152 (58.5%) females aged between 5 and 78 years. The clinical distribution of the lesions were 127 (48.8%) with skin lesions and 133 (51.2%) with oral mucosal lesions. The duration of disease ranged from 1 to 240 months. In 140 of 260 LP cases, hepatitis serology and pre-prandial blood glucose were examined. We found HBV positivity in 24 (17.1%) cases, Anti-HCV positivity in 7 (5%) cases, and DM in 22 (15.7%) cases. The control group included 116 (41.4%) males and 164 (58.6%) females. Their ages ranged between 10 and 82 years. In this group, we found HBV positivity in 20 (7.1%), Anti-HCV positivity in 4 (1.4%), and DM in 20 (7.1%) cases. We believe that the co-association of LP with HCV is significant and this co-association ratio indicates variance depending on clinical attributes of the lesions and racial characteristics of the patients. Although we found co-associations between HBV and LP or DM and LP, we believe that further studies are necessary to determine if they are significant.

Two hundred four patients (117 females, 87 males; age range: 3-80 y) were admitted to our facility between May 1995 and June 1997 and studied to determine the endemicity of the Paederus species, which has been increasing for the last 6 years (especially in May and June) in the Cukurova region of southern Turkey. Clinically, infection with the Paederus species mimics contact dermatitis, herpes zoster, bullous impetigo, and phytophotodermatitis. Definitive diagnosis is made by historical and clinical findings. To determine the main histopathologic features of this infestation, biopsy specimens were obtained from 9 patients and stained with hematoxylin and eosin (H&E). In most patients, the skin lesions were located on the exposed parts of the body. Clinically, these lesions were linear, vesicular, bullous, and/or pustular on erythematous bases and resembled either phytophotodermatitis, herpes zoster, or impetigo rather than classic insect bites. Pederin, which is released from the Paederus species, may cause these lesions. The number of cases has increased markedly during the last 5 years. In the coming years, we expect this number to increase significantly.
