Congenital cerebriform melanocytic naevus with cutis verticis gyrata.

Congenital melanocytic naevus is hamartomatous or non-neoplastic proliferation of abnormal mixture of tissue's or non-neoplastic proliferation of abnormal mixture of tissue's normal components. Cutis verticis gyrata is hypertrophy with parallel or gyrate folds of skin of scalp.

Clinico-epidermiological studies on tinea versicolor.

One hundred and twenty patients with tinea versicolor who attended the outpatient department of Dermatology, K.M.C Hospital, Mangalore were studied with reference to their clinical features, age and sex distribution, relation to climate and personal habits. The disease was commonest among the age group of 21-30 years (30%). It was found to be distributed predominantly over the neck (71.6%), chest (58.3%) and back (70%). Inmost of the patients, lesions were observed first and also aggravated during summer months. One fourth of the patients either had systemic diseases or were on immuno-suppressant drugs. The disease was continuous in spite of taking treatment in 21.6% of patients. 38.3% of patients gave a positive family history. Even though the disease is resistant to treatment, avoiding the predisposing factors like increased sweating, sharing the towels and clothes, malnutrition, synthetic clothings will help to control the disease.

Occupational dermatoses in beedi rollers.

A total of 91 beedi workers were analyzed for the pattern of cutaneous lesions. Period of rolling beedi ranged from 2 months to 40 years. Dermatological findings included; callosities seen in 51 (56.04%) of workers on fingers and feet, nail changes in 22 (24.18%) like pigmentation, paronychia, dystrophy which were more prominent on the right index finger, fungal infections in 15 and eczemas in 29. Callosities and localised nail changes can be considered to be occupational marks in beedi rollers correlated to use of scissors for cutting leaves and use of gum and artificial metallic nails for rolling beedis.
