We analyzed the records of 211 pediatric patients with vitiligo. 57.8% of patients were females and 42.2% were males. Leukotrichia and family history were present in 29.4% and 15.6% of patients, respectively, while 39.3% of patients had anemia.Elevated thyroid-stimulating hormone and fasting blood glucose levels were seen in 5.2% and 3.3% of patients, respectively. Antinuclear antibody was positive in 12 (5.6%) patients.

We analyzed records of 30 patients with lichen striatus (age < 18 years) in this retrospective study. Seventy percent were females and 30% were males with a mean age of diagnosis of 5.38 ± 4.22 years. The most common age group affected was 0-4 years. The mean duration of lichen striatus was 6.66 ± 4.22 months.Atopy was present in 9 (30%) patients. Although LS is a benign self-limited dermatosis, long-term prospective studies with a greater number of patients will help in better understanding of the disease including its etiopathogenesis and association with atopy.

Acne is a chronic inflammatory disease of pilosebaceous unit characterized by formationof comedones, papules, pustules, and nodules of varying degree of inflammation and depth. 1 It is principally a disorder of adolescence. However, the prevalence of adult patients with acne is increasing and women comprise majority of cases. Adult acne is defined as acne that develops (late-onset acne) or continues (persistent acne) after 25 years of age. 2 Increased sebum production, follicular hyperkeratinization, Propionibacterium acnes colonization and inflammation play an interactive pathogenic role in acne. There are 2 clinical types: (1) Persistent acne (2) Late-onset acne. Both types of

Rationale: Though cutaneous tuberculosis accounts for a small proportion of all tuberculosis cases, it becomes an important health issue considering its high prevalence in tropical countries. Due to its myriad clinical manifestations, it becomes difficult to diagnose and may pose a great diagnostic dilemma. Patient concerns: A 17-year-old male complaint of ulcerproliferative lesion on the left lower leg for 5 years. There was no history suggestive of tuberculosis. On cutaneous examination, single well-defined erosiocrustive plaque of size 14 cm × 13 cm with yellowish adherent crust presented over the left lower leg. The underlying surface shows ulceration after removing the crust. Diagnosis: Ulcerative Lupus vulgaris. Interventions: Anti-tubercular drug therapy (isoniazid, rifampicin, pyrazinamide and ethambutol). Outcomes: Lesion showed dramatic improvement after one month of anti-tubercular therapy. Lessons: Dermatologists should be aware of variable clinical presentations of cutaneous tuberculosis so as to diagnose it timely and correctly.
