We report here 11 cases of vitamin K deficiency bleeding (VKDB), despite receiving appropriate dosage of injectible vitamin K at birth. Bleeding symptoms ranged from excessive bleed from cuts to intracranial bleed. Tuberculosis, diarrhea with intermittent antibiotic therapy were some of the associated symptoms. Laboratory tests confirmed acquired bleeding diathesis due to vitamin K deficiency, which was corrected after adequate vitamin K supplementation. VKDB is not an uncommon phenomenon and should be considered in the differential diagnosis of a child with bleeding diathesis. © 2010 Lippincott Williams & Wilkins, Inc.
