  Fig. 1 (A) A solitary, mild bluish to skin-colored, hard mobile nodule on the extensor surface of the left forearm measuring 1×1 cm (black arrow). (B) Using ultrasonography, a well-defined oval isoechoic mass of about 10×7×10 mm, with moderate hyperemia, was determined in the subcutaneous fat layer on the left forearm. (C) Deep well-defined multinodular tumor with basophilic lobules encapsulated by thick connective tissue in the dermis and subcutaneous layer. A trabecular arrangement or clusters of deep basophilic cells were present (H&E, ×40). (D) In the nodule, two types of cells (small, dark, basaloid cells with hyperchromatic nuclei, and cells with large, pale, vesicular, and ovoid nuclei) were seen. The center of the lesions was composed of pale cells and duct like structures. The mitotic activity was low and there was no necrosis (H&E, ×200).
