Pilomatricoma is a benign skin tumor derived from the hair follicle, usually located in the head and neck and presenting in the first two decades of life. Clinically it most commonly presents as a hard, mobile, well circumscribed nodule. Microscopically it is characterized by the presence of shadow cells and may show calcification, while extensive ossification is rare. Surgical removal is the treatment of choice, as the recurrence rate is very low. We present a rare case of late regressive pilomatricoma of the arm in a 33 year old female which presented with extensive ossification.
毛母质瘤是一种来源于毛囊的良性皮肤肿瘤，通常位于头颈部，好发于生命的头 20 年。临床上，它最常见的表现为坚硬、可移动、边界清楚的结节。显微镜下，其特征是存在影子细胞，可能伴有钙化，而广泛的骨化则很少见。手术切除是首选治疗方法，因为其复发率非常低。我们报告了一例罕见的 33 岁女性手臂迟发性退行性毛母质瘤，其表现为广泛骨化。
