Fig. 25.11.Fine-needle aspirate cytology of a histiocytoma: pleomorphic round cells with basophilic cyto-
plasm and round to slightly indented nuclei.
Fig. 25.12.Biopsy tissue of a nodule from the patient in Figure 25.6 with reactive cutaneous histiocytosis.
Note that grossly, inflammation appears to spare the epidermis (white arrowhead) and predominantly affects the
