Abstract

Malignant melanoma of the conjunctiva is a rare tumor of the ocular surface with potential fatal consequences and a high likelihood of recurrence. Although routes for extending the tumor, including local, hematogenous, and lymphatogenous, are pretty straightforward, the indirect extension through free-floating tumoral cells to the nasolacrimal duct is not described thoroughly. We report a case of malignant melanoma of the conjunctiva which presented with local recurrence in the intranasal cavity and lacrimal sac two years after the primary surgery (without involvement of the ocular surface and punctum on the second occasion). However, there was no evidence of distant metastasis on either occasion. This case demonstrates the possible noncontiguous spreading route of melanoma tumoral cells and highlights the need for attention to the surgical technique, and careful follow-up to detect further disease activity.

结膜黑色素瘤完全治疗后的泪腺引流系统和鼻腔黑色素瘤
结膜恶性黑色素瘤是一种罕见的眼表肿瘤,具有潜在的致命后果,而且复发的可能性很高。虽然肿瘤的扩展途径(包括局部、血源性和淋巴管源性)非常简单,但通过自由漂浮的肿瘤细胞间接扩展到鼻泪管的情况却没有得到详细描述。我们报告了一例结膜恶性黑色素瘤病例,该病例在初次手术两年后在鼻腔内和泪囊局部复发(第二次没有累及眼表和穿刺点)。不过,这两次都没有远处转移的迹象。本病例显示了黑色素瘤肿瘤细胞可能的非连续性扩散途径,并强调需要注意手术技巧和仔细随访,以发现进一步的疾病活动。
