You are correct. Capsule endoscopy revealed whipworms, Trichuris trichiura, a major nematode species affecting the human bowel, in the ileocecal valve. Ultrasound findings of thickened ileal wall and fluid-filled loops are not pathognomonic, but in the clinical context raise the suspicion of a malabsorption condition. The patient recovered rapidly with a course of mebendazole and short-term iron supplementation.

You are correct. The image shows molluscum-associated dermatitis caused by the molluscipoxvirus. The small, pearly, dome-shaped papules with central umbilication favor intertriginous areas, although they may appear anywhere. Molluscum contagiosum infection may result in an associated dermatitis thought to be secondary to a delayed hypersensitivity reaction to the virus. The specific onset of dermatitis confined to the site of the molluscum favors the diagnosis of molluscum-associated dermatitis over atopic dermatitis. The condition is usually self-limited.
