Pilomatrixoma or pilomatricoma is an uncommon benign tumor of hair matrix origin, which most commonly occurs in the head and neck region and upper extremities. In this study, we report a case of pilomatrixoma of a 35-year-old female presenting with left-leg swelling with surface ulceration, clinically thought to be malignant. Fine-needle aspiration cytology (FNAC) of the lesion showed clusters of basaloid cells with round to ovoid nuclei, nucleated squamous cells, and anucleated squames and clusters of shadow cells. Acytological diagnosis of pilomatrixoma was made. Subsequent surgical excision and histopathological examination confirmed the diagnosis. This case highlights a rare site of presentation and the role of FNAC in preoperative diagnosis of this benign tumor for proper management.
毛母质瘤是一种起源于毛发基质的罕见良性肿瘤，最常发生于头颈部和上肢。在本研究中，我们报告了一例35岁女性的毛母质瘤病例，该患者表现为左腿肿胀伴表面溃疡，临床怀疑为恶性。对病变进行细针穿刺细胞学检查（FNAC），结果显示有基底样细胞簇，细胞核呈圆形至卵圆形，有核鳞状细胞、无核鳞状上皮细胞以及影细胞簇。做出了毛母质瘤的细胞学诊断。随后的手术切除及组织病理学检查证实了该诊断。本病例突出了这种良性肿瘤罕见的发病部位以及FNAC在其术前诊断以进行恰当治疗方面的作用。
