Case presentation

A 19-year-old Iraqi woman is being evaluated. She has a large mass on the posterior aspect of her neck that had appeared after birth and had increased in size and thickness in the last 4 years, associated with itching and bad odor. She had no neurologic symptoms. On examination, the patient had a large, disfiguring, hyperpigmented, firm mass with a nodular surface, about 21 × 7 × 4 cm, extending from the occipital region to the upper back through the posterior aspect of the neck (Fig 1). The entire lesion was excised, and a partial-thickness skin graft was performed. Excisional biopsy specimen was sent for histopathologic examination (Fig 2, A and B) and immunohistochemistry (Fig 3, A [MART-1/Melan-A stain] and B [S100 stain] ).
