Paraffinoma of the penis is a rare but potentially debilitating consequence of subcutaneous mineral-oil injection for penile enlargement. We report a 34-year-old male who presented after failed urethral catheterization with diffuse penile induration and pain during intercourse, following self-injection of paraffin into the preputial region. Clinical assessment and penile ultrasound with color Doppler supported the diagnosis; histology confirmed sclerosing lipogranuloma without malignancy. The patient underwent complete degloving, radical excision of infiltrated tissues, and reconstruction using full-thickness skin grafts harvested from the right biceps and left thigh. Postoperative care included compression dressings and targeted antibiotics, with satisfactory graft take and acceptable cosmetic outcome at 10 and 40 days. Persistent dissatisfaction with penile size highlighted the need for integrated psychological assessment alongside surgical management.

皮下石蜡注射后石杨瘤：病例报告和手术治疗

石二酚瘤是皮下注射矿物油治疗增大的一种罕见但可能使人衰弱的后果。我们报告了一名 34 岁男性，他在包皮区域自行注射石蜡后，在导尿失败后出现弥漫性硬结和疼痛。临床评估和彩色多普勒超声支持诊断;组织学证实硬化性脂肪肉芽肿，无恶性肿瘤。患者接受了完全脱手套、根治性浸润组织切除，并使用从右二头肌和左大腿采集的全层皮肤移植物进行重建。术后护理包括加压敷料和靶向抗生素，在 10 天和 40 天时移植物采集令人满意，美容结果可接受。对大小的持续不满凸显了在手术管理的同时进行综合心理评估的必要性。
