右側鼻翼旁先天性黑色素痣手術切除案例：
一顆位於右臉部、靠近右側鼻翼，鼻唇溝上方的先天性黑色素痣，經手術成功切除。該痣呈現大型、圓形、漆黑色澤，直徑超過1.2公分，高出皮膚表面約1.0公分。邊界清晰，界線分明，表面可見毛囊開口。病灶表面密集生長粗厚終毛，超過15根粗黑毛髮自痣中穿出。此痣自出生即存在，並在27年間逐漸增大。術前未見潰瘍、分泌物或形態改變等異常現象。
Case study of excising a huge mole on the upper end of right naso-labial fold, next to nose ala.
A solitary, congenital pigmented nevus was surgically excised from the right facial region, specifically the upper nasolabial fold near the right ala. The mole presented as a large, round, pitch-black lesion with a diameter exceeding 1.8 cm. It was well circumscribed, with clearly defined borders and visible follicular openings.
The surface demonstrated dense terminal hair growth, with over 15 thick hairs emerging from the lesion. The mole had been present since birth, with progressive enlargement over a 27-year period. No signs of ulceration, discharge, or recent morphological changes were noted prior to excision.

🩺 病例報告：右側上鼻唇溝先天性色素痣
病人概況
一名27歲女性，右側面部（靠近右鼻翼的上鼻唇溝）自出生即存在一顆孤立的先天性色素痣。該痣在27年間逐漸增大。
臨床表現
該痣呈現大型、圓形、漆黑色病灶，直徑超過1.8公分。邊界清晰、界限分明，表面可見毛囊開口。痣表面長有密集的終毛，超過15根粗硬毛髮自病灶中生長出來。未見潰瘍、分泌物或近期形態改變。病灶無症狀，外觀穩定。
處理與手術
考慮到病灶的大小、位置及美觀影響，在局部麻醉下進行手術切除。手術中包含部分正常皮膚邊緣以確保完整移除。切除後的標本送交病理檢查。
病理結果
顯微鏡檢查證實為良性先天性黑色素痣。未見異型增生、發育不良或惡性變化。
術後結果
手術傷口小，使用細線縫合。癒合後疤痕隱藏於鼻唇溝自然皺褶中，幾乎不可見。無併發症，病人對外觀及治療結果表示滿意。
討論
先天性色素痣為出生即存在的黑色素細胞病灶，可能隨身體成長而逐漸增大。雖多數為良性，但若病灶較大或影響外觀，尤其伴隨濃密毛髮者，常因美觀或心理因素而考慮切除。本病例中，病灶位於鼻唇溝，術後疤痕隱藏效果良好，顯示精準手術技術在面部痣切除中的重要性。病理結果確認良性，為病人提供安心保障。
🩺 Case Report: Congenital Pigmented Nevus of the Right Upper Nasolabial Fold
Patient Profile
A 27-year-old male presented with a solitary congenital pigmented nevus located on the right facial region, specifically along the upper nasolabial fold adjacent to the right ala. The lesion had been present since birth and demonstrated gradual enlargement over the course of 27 years.
Clinical Presentation
The nevus appeared as a large, round, pitch-black lesion with a diameter exceeding 1.5 cm. It was well circumscribed, with sharply defined borders and visible follicular openings. The surface exhibited dense terminal hair growth, with more than 15 coarse hairs emerging from the lesion. There were no signs of ulceration, discharge, inflammation, or recent morphological changes. The lesion was asymptomatic and stable in appearance.
Management and Procedure
Given the lesion’s size, location, and cosmetic impact, surgical excision was performed under local anesthesia. A margin of clinically normal skin was included to ensure complete removal. The excised specimen was submitted for histopathological examination.
Histopathology
Microscopic analysis confirmed the diagnosis of a benign congenital melanocytic nevus. No atypia, dysplasia, or malignant transformation was observed.
Postoperative Outcome
The surgical wound was small and closed with fine sutures. The resulting scar was well concealed within the natural contour of the nasolabial fold and was barely visible upon healing. No complications were noted, and the patient expressed satisfaction with both the aesthetic and clinical outcome.
Discussion
Congenital pigmented nevi are melanocytic lesions present at birth and may enlarge proportionally with growth. While most remain benign, large or cosmetically prominent lesions—especially those with dense hair growth—may warrant removal for aesthetic or psychological reasons. In this case, the lesion’s location near the nasolabial fold posed a challenge for scar concealment, which was successfully addressed through precise surgical technique. Histological confirmation of benignity provided reassurance, and the outcome demonstrated the value of individualized treatment planning in facial mole excision
