Compound Spitz tumor without significant atypicality of a 22-year-old male with lesion involving the left upper arm. The lesion measures less than 10 mm in diameter and 0.61 mm in Breslow thickness. Other attributes: no asymmetry, sharp circumscription, no ulceration, only minimal focal pagetoid spread, and there are no mitoses in the small dermal component. This lesion requires complete excision and the patient follow-up examinations at least once a year for example. (a) Scanning magnification show a slightly raised tumor with general symmetry. (b) The lesion demonstrates orderly appearance with regular junctional nesting and small dermal component. (c) The lesion shows focal pagetoid spread and fairly regular junctional nesting of melanocytes. (d) Note uniformity of spindle and epithelioid cells in the dermis.
