BACKGROUNDMost dermatological diseases generally occur elsewhere and also involve the genitalia. If the lesion is present exclusively on genitalia, it is a difficult task for the treating doctor to differentiate non venereal from venereal genital lesions.Aim is to study the clinical pattern and prevalence of non-venereal genital dermatoses. MATERIALS AND METHODSIt is a descriptive study of adult new cases with genital lesions attending Skin and STD Outpatient Clinic of Coimbatore Medical College Hospital for a period of one year from August 2013 to July 2014. Clearance was obtained from Ethical Committee. RESULTSA total of 150 cases (114 males, 36 females) with non-venereal genital dermatoses were encountered in our study. Prevalence of the non-venereal genital dermatoses in the study was 2.6 per 1000 cases. Male-to-Female ratio of patients in our study was 3.16:1. Majority of the patients were found in the age group of 33 to 42 years [42 (28%)]. Commonest non-venereal genital dermatosis was found to be scabies occurring in 19 (12.6%) patients. Pearly penile papule was found to be more common [10 (6.6%)] among benign conditions and normal variants. Among inflammatory conditions and miscellaneous groups, contact dermatitis and vitiligo were the commonest conditions respectively. One case of verrucous carcinoma of penis was seen. CONCLUSIONAll lesions occurring over genitalia are not sexually transmitted. Scabies was the most common non-venereal genital dermatosis in our study. Identifying the common non-venereal genital conditions will also remove venereophobia.

Introduction: Nail changes are always a cause of physical handicap and psychological stress in this era where utmost importance is given to cosmetic appearance. Other than trauma and infections, Papulosquamous disorders are major contributor to nail changes. Thorough knowledge of their patterns will aid in early detection and treatment before irreversible damage to nails occurs. Aim: To observe the clinical patterns of nail changes in various papulosquamous disorders. Materials and Methods: This observational descriptive cross- sectional study was conducted in a tertiary care set up at Government Coimbatore Medical College, Coimbatore from June 2016 to June 2017. The study group comprised of 104 cases of various papulosquamous disorders. The type of papulosquamous disorder, presence of nail changes, their onset, duration, various patterns and associated co-morbidities were noted in detail. The observed data were entered in Microsoft Excel and data analysis was done in Epi Info system. Results: Out of the 104 cases taken for study 71 (68%) had nail changes. Majority of them were in 31-45 years age group (n=29; 41%). More of males (n=38, 54%) had nail changes than the females (n=33, 46%). Psoriasis (n=47; 66%) was the most common papulosquamous disorder with nail changes followed by lichen planus (n=9; 13%) and pityriasis rubrapilaris (n=7; 10%). Pitting of nails was the most common nail pattern (n=44; 62%), followed by subungual hyperkeratosis (n=24; 34%), thickened nail plate and longitudinal striations (both n=19; 27%). Finger nails were more affected than toe nails. Psoriasis and pityriasis rubrapilaris had 100% nail involvement. The patterns of nail changes were maximum in psoriasis and lichen planus. Beaus lines was observed in most of the papulosquamous disorders except Lichen nitidus and Lichen striatus. The time gap for onset of nail changes was longer for psoriasis (4.2 years) and shorter for pityriasis rosea (two months). In lichen striatus and lichen nitidus, nails were involved only in children. Minimal nail changes were observed in para psoriasis and pityriasis lichenoides. More number of co-morbidities like diabetes, hypertension, atopy and arthritis were seen in psoriasis. Conclusion: In the present study, it was observed that the nail changes were more common in psoriasis, lichen planus and pityriasis rubra pilaris among the papulosquamous disorders. The highly frequent nail patterns were pitting and subungual hyperkeratosis.

BACKGROUNDPalmoplantar psoriasis that accounts for 3% -4% of all psoriasis cases produces significant functional and social disability. Reduction of pain and improvement in the function of limbs are more important therapeutic goals than complete clearance. This prospective, randomised, controlled study was conducted in Coimbatore Medical College, a tertiary care centre in Tamilnadu. We conducted the study on 50 patients from September 2011 to November 2012. Aims and Objectives-The aims and objectives of the study was to compare the efficacy, to observe the reduction in percentage of psoriasis area and severity index score (PASI SCORE) above 50% and to observe the adverse effects in first 6 months and duration of remission in the next 6 months.

A 52 year old woman presented with a history of asymptomatic skin lesions over left leg for the past 4 months. On examination she had multiple skin coloured papules and plaques over left leg. Oedema was also seen over left leg. Histopathology and immunohistochemistry proved the diagnosis of malignant melanoma. Radiological investigation showed metastasis to lung, liver and brain. The patient was asymptomatic at the time of admission but she developed rapid metastasis within a very short span of time. This case is reported for the rare atypical presentation of malignant melanoma.
