(A) Lymphocytic and histiocytic infiltrate (solid black arrows) in a lobular
pattern in the subcutis. (B) Adipocytes in subcutis are rimmed by mild to
moderately atypical lymphoid cells (solid black arrows). Histiocytes some
with phagocytosed hematic cellular fragments (solid yellow arrows). (C)
Adipocytes in subcutis are rimmed by mild to moderately atypical,
hyperchromatic lymphoid cells (solid black arrows). An occasional mitotic
figure is present (solid yellow arrow).
