(A) Tumor cells in a sheet-like pattern, showing round to oval nuclei with eosinophilic cytoplasm and no obvious atypia or mitosis (hematoxylin and eosin 400x). (B) Tumor cells are strongly positive with smooth muscle actin immunostaining (400x).

There was no atypia or malignant cells (Figures 1A and 2). Immunostaining with smooth muscle actin was diffusely positive, which supported the diagnosis of solid glomus tumors (Figure 1B).
Lower magnification demonstrates a sheet-like pattern of monotonous round-avoid tumor cells (hematoxylin and eosin, 100x).
