Recognizing Skin Popping Scars: A Complication of Illicit Drug Use.

"Skin popping" is a method of injecting illicit drugs into the skin. There are numerous acute and chronic complications associated with skin popping. We present a case of a 48-year-old, African-American female patient with 40 - 60 hyperpigmented, fibrotic, depressed, round papules and plaques on the extremities, which were incidentally noticed during a clinic visit for her acne vulgaris. Skin popping scars are important clues for possible drug abuse. Healthcare practitioners should be aware of and recognize the lesions associated with this practice so further testing can be performed if clinically indicated. Recognition of the lesions and thus earlier treatment of the complications could prevent the complications of skin popping in the skin and other organs.

A Vascular-appearing Spindle Cell Xanthogranuloma in a Child.

Spindle cell xanthogranuloma is a rare variant of juvenile xanthogranuloma that most commonly presents in adults as papulonodules. We describe a vascular-appearing case of spindle cell xanthogranuloma on the nose of a 10-year-old boy. The lesion was a dark red, well-demarcated, dome-shaped papule. Histopathology revealed spindle-shaped histiocytes in a storiform pattern that stained positive for cluster of differentiation 68 (CD68) and the nuclear antigen Ki-67. No vascular features were found. To our knowledge, this is the first reported spindle cell xanthogranuloma to mimic an angiomatous lesion.
