Plasmacytoma, primary or secondary. The "clock face" or "spoke wheel" chromatin, basophilic cytoplasm, eccentrically located nuclei and paranuclear light "hoff", corresponding to the Golgi area are typical characteristics of plasma cells.

Cutaneous plasmacytoma. Almost certainly patient has an underlying or a past history of multiple myeloma.

Skin infiltration by a Plasma cell neoplasm. Based on the age of the patient, he probably has an underlying systemic disease, so this must be a Cutaneous infiltration by Multiple Myeloma.

Yes we reported this as a plasmacytoma (Kappa light chain restriction). We recommended correlation with radiology and biochemical testing to rule out systemic disease. There was no history of myeloma.
