Abstract: 8 yo boy with few months history of erythematous papule right calf
HPI: This 8 yo boy was originally seen in August 2013 for a lesion on the right calf whih had been present for 2 months. Clinically, it looked like a pyogenic granuloma. It was shave excised and the base cauterized. A specimen was sent for pathology, but the report was not seen. Three months later his parents called to say the lesion had recurred. The biopsy report was checked and it was learned that this was an atypical Spitz nevus. The patient was seen in follow-up for a reexcision.
O/E: On both occasions, the lesion was an erythematous papule measuring 8 mm in diameter. It looked vascular.
Diagnosis: Atypical compound spindle and epithelioid cell (Spitz) nevus
Discussion: These are difficult lesions histologically. In untrained eyes, they can be mistaken for melanoma or STUMP (Spitzoid tumors of uncertain malignant potential) lesions. Pathologically, this lesion was felt to be benign and the patient will be followed.
References: These references will be helpful in managing this and similar patients.
