Pigmented spindle cell
nevus (Reed Nevus): Pigmented spindle cell naevus is regarded as a distinct entity and not part of spindle cell variant of Spitz naevus. Clinically, these lesions present as symmetrical ,sharply circumscribed, darkly pigmented nodule or papule ( usually less than 0.6 cm in diameter). Image1 ; Image2 Histologically, the tumour consists of spindle shaped cells in nests with formation interconnecting fascicles. Image1 ; Image2 ; Image3 ; Image4. Prominent vertical orientation of cells are noted. The tumour grows in an expansile. These are heavily pigmented and contains melanophages. Kamino bodies (similar to Spitz) are noted in pigmented spindle cell naevus. Junctional clefting is noted in some cases. Differential diagnosis include melanoma. Unlike melanoma these are symmetrical lesions and display maturation of cells in the deeper part of the lesion. Pagetoid spread of cells is limited to the lower half of the epidermis.
