External genitalia of male is common site for rashes, itching and minor infections. Because of its anatomical variation, the area is always warm, moist and occluded, which predisposes to occur many dematoses. These dermatoses can be divided into two groups: venereal dermatoses and nonvenereal dermatoses. Non-venereal dermatoses are the diseases which are not sexually transmitted. 1: To study the pattern of non-venereal dermatoses of adult male genitalia of patients of age 18 years and above; 2: To study frequency of various non-venereal dermatoses among that population. The study was conducted in the Department of Dermatology, Silchar Medical College & Hospital, Silchar, Assam over a period of one year extending from 1st June 2018 to 31st May 2019 after satisfying all the inclusion and exclusion criteria. It was a clinical observational study (cross sectional study). In the study, we came across 152 male patients of age 18 years and above. The prevalence of non-venereal dermatoses of male genitalia was found to be 54 per 10,000 populations. The mean age of presentation was 35.5 years. Pearly penile papule was the most common presentation among normal variants with 5.9% patients. Among inflammatory dermatoses eczematous dermatoses was most common dermatoses with 14.47% patient. Among miscellaneous cutaneous genital conditions, vitiligo was the only dermatoses we found with 17.11% patients. Scabies was the most common among infections and infestations with 9.9% patient. Sebaceous cyst was the most common benign tumour with 3.3% patient. Among pre-cancerous lesions, we found 2(1.3%) cases of porokeratosis and 1(0.66%) case of penile horn. We found 3 cases of squamous cell carcinoma (2%) in our study. With the knowledge of clinical pattern of the non-venereal dermatoses in an area, clinical diagnosis of common dermatoses can be made easily. It is a common misbelieve among the patients that all dermatoses occurring in the genitalia are manifestations of sexually transmitted diseases. So, proper knowledge of these non-venereal dermatoses helps to create awareness among patients

Pemphigus is an autoimmune bullous disease. Septicemia is one of the common causes of death which is usually secondary to cutaneous bacterial infection. 1: To study the cutaneous bacteriological profile and the most common cause of bacterial skin infection in pemphigus patients; 2: To find out the antibiotic sensitivity pattern in pemphigus patients of Northeastern part of India.This was a descriptive type of cross-sectional study conducted at Dermatology, Venereology and Leprosy department of Silchar Medical College from January 2021 to December 2021. A total of 33 confirmed inpatient cases of pemphigus was selected via non probability convenient sampling method. Pus for culture was collected, to study the common cause of bacterial skin infections and antibiotic sensitivity pattern in pemphigus patients. Out of 33 patients included in the study, male patients were 22 and female patients were 11. Pemphigus vulgaris was noted in 28 patients, pemphigus foliaceous was found in 4 patients and 1 patient was of pemphigus vegetans. The mean age was found to be 35.6 years and 36.36% patients were diabetics in our study. About 45.4% patient’s pus culture report showed the growth of Staphylococcus aureus, 18.1% showed the growth of Proteus mirabilis, 6.06% showed the growth of nonfermenting gram negative bacilli, 3.03% showed the growth of Klebsiella species and Beta hemolytic streptococci, 9.09% showed the growth of skin commensals and 15.15% showed no growth. Staphylococcus aureus showed 100% sensitivity to linezolid, amikacin and tetracycline; 86.6% resistance was seen for penicillin, 80% resistance was seen for levofloxacin, 60% resistance was seen for clindamycin, 66.6% resistance for cotrimoxazole was seen and 33.3% resistance was seen for azithromycin. Proteus mirabilis showed maximal sensitivity to ciprofloxacin, amikacin, gentamicin, ceftazidime, piperacillin + tazobactam and meropenem. Staphylococcus aureus is the most common organism causing skin infections in pemphigus patients and it has maximal sensitivity to linezolid, amikacin and tetracycline
