Young adults
LocalizationThis section has been translated automatically.
In one of this retrospective clinicopathologic study, "scalloped -cell -xanthogranuloma" occurred mostly on the back or head and neck of young adult males.
Clinical featuresThis section has been translated automatically.
Yellow or red papules and nodules with a diameter of 0.5-1.0cm. These are usually diagnosed as melanocytic nevi, pigmented fibromas or basal cell carcinomas.
HistologyThis section has been translated automatically.
Histology characteristically showed a planar infiltrate of predominantly scalloped histiocytes (> 79% of all cell types) in the upper dermis. Other mononuclear (vacuolated, xanthomatized, spindle-shaped, oncocytic) and multinucleated (foreign body and touton) histiocytes were also regularly observed.
Immunohistochemically, cases exhibit a macrophagocytic/dendritic cell lineage, with positivity for CD68, KiM1p, HAM 56, and factor XIIIa .
Ultrastructurally, numerous intracytoplasmic dense, occasionally myeloid corpuscles are found present.
