Non-venereal dermatoses of female external genitalia include a spectrum of diseases with varied etiology. The most common non-venereal dermatoses in males were scrotal dermatitis seen in 16.6% patients, vitiligo was seen in 14.3% patients, fixed drug eruption, scabies and pearly penile papules were seen in 10% patients each. Sebaceous cyst, tinea, psoriasis and lichen planus was seen in 6.6% patients each. Balanitis xerosus obliterans, squamous cell carcinoma and verrucous carcinoma and achrochordon were seen in 3.3% patients each. The most common genital dermatoses seen in females were lichen sclerosus (15%), vitiligo (15%) and vulval candidiasis in 15% cases. Other non venereal genital dermatoses in females were lichen simplex atrophicus (10%), bartholin cyst (10%), tinea (10%), psoriasis (10%), vulval lymphoedema (10%) and achrochordon in 5% patients.

Certain dermatoses are specifically seen in pregnancy or postpartum period. It is therefore important for the clinicians to recognize and treat these cutaneous disorders to minimize maternal and fetal morbidity. The commonest pregnancy related dermatoses was polymorphic eruption of pregnancy seen in 22% patients, prurigo of pregnancy was seen in 7% patients, pemphigoid gestationis was seen in 3% patients, pruritic folliculitis of pregnancy was seen in 2% patients and intrahepatic cholestasis was seen in 1% of patients. It was seen that the skin disorders were commonest in the third trimester (60%), followed by 31% patients in second trimester and 9% patients in first trimester.

P-Phenylenediamine is an oxidative chemical that is frequently used as a permanent hair-coloring agent. It is added to henna to increase the intensity and longevity of the tattoo and expedites its drying time. Henna itself is a greenish brown vegetable coloring made from the leaves of Lawsonia inermis and rarely causes allergic contact dermatitis. The addition of PPD causes the contact sensitization to black henna. Serious adverse skin reactions to permanent hair dyes and temporary black tattoos have been reported. As temporary tattoos have become fashionable among adolescents, the risk profile for p-phenylenediamine (PPD) sensitization of the population has changed simultaneously with an increasing use of hair dyes in this age group. With increased popularity of body art such as body piercing and tattooing, an increase in temporary henna tattoos has also occurred. Although the appeal of non-permanence exists for henna tattoos, dermatologists have begun to see numerous cases of allergic contact dermatitis linked with a certain type of henna. We selected 50 patients using hair dye and henna for our study. Patch testing was done in all the patients using Indian standard series of antigens. Regarding to the side effects to hair dye and henna and itching was the commonest symptom seen in 16% patients, erythematous scaly plaques were seen in 10% patients, vesicular reactions were seen in 6% patients, angioneurotic oedema and contact urticaria was seen in 4% patients each and anaphylaxis and keloidal reaction was seen in 2% patients each.

Introduction: Tinea capitis is a superficial fungal infection of scalp and hair caused by various species of dermatophytes. The incidence of Tinea capitis varies from country to country and region to region. Material and Methods: Fifty patients from the preschool going population were selected for the study. Results and Discussion: Clinical presentation of disease revealed that black dot to be the commonest (32%) followed by grey patch (28%), kerion (20%) and favus type was the least (1%). Direct microscopy of hair in KOH preparations revealed that all clinically suspected patients of Tinea capitis had endothrix type in 56% of cases and ectothrix type in 44%.

Introduction: Cicatrical alopecia occurs in otherwise healthy men and women of all ages and is seen worldwide Material and Methods: A study of 40 patients was conducted to study the clinical variants and histopathology of cicatricial alopecia. Results and Discussion: n our study, it was seen that maximum number of cases of cicatrical alopecia were of LPP (27.5%) followed by 25% of DLE, 20% patients had pseudopelade of Brocq, SLE was seen in 5% cases followed by Scleroderma, dermatomyositis, Keratosis follicularis spinulosa decalvans, aplasia cutis, kerion, follicular mucinosis, pemphigus, dissecting cellulitis of scalp/ pyogenic folliculitis and acne keloidalis nuchae in 2.5% cases each. Regarding the morphology of lesions,epidermal atrophy was seen in 90% patients, erythema was seen in 55% cases, follicular pluging was seen in 40% patients, telangiectasias in 27.5% patients, diffuse scaling in 25% patients and mottled hyperpigmentation was seen in 20% patients. In our study, commonest histopathological feature of alopecia was perifollicular fibrosis seen in 65% patients, basal cell vacuolization was seen in 52.5% patients,perifollicular lymphocytic infiltrate were seen in 50% patients, epidermal atrophy seen in 35% patients and hyperkeratosis was seen in 20% patients.
