Onychomatricoma is a rare benign tumor originating in the nail matrix. Only eight cases have been reported until now.
The clinical and histopathological features of this recently reported tumor will be described and its differential diagnoses outlined. A typical case of onychomatricoma is described in a 62-year-old white man.
Clinically, onychomatricoma is characterized by: 1) a yellowish discoloration of a longitudinal segment of the nail plate with small splinter hemorrhages within the proximal portion of the nail; 2) a thickening with increased transversal curvature of the involved nail plate positively corresponding with the yellow discoloration; and 3) a matrix tumor consisting of multiple fine filiform projections that extend into the thickened nail plate. The treatment of onychomatricoma is complete excision of the tumor.
Onychomatricoma is a new entity with clinical and histopathological features that are characteristic enough to make the correct diagnosis.
甲母质瘤是一种起源于甲母质的罕见良性肿瘤。迄今为止，仅报道过8例。
描述这种最近报道的肿瘤的临床和组织病理学特征，并概述其鉴别诊断。描述了一名62岁白人男性的典型甲母质瘤病例。
临床上，甲母质瘤的特征为：1）甲板纵向部分发黄，甲近端有小的裂片样出血；2）受累甲板增厚，横向弯曲增加，与发黄区域正好对应；3）基质瘤由多个细的丝状突起组成，延伸至增厚的甲板。甲母质瘤的治疗方法是完整切除肿瘤。
甲母质瘤是一种具有足以做出正确诊断的特征性临床和组织病理学特征的新病种。
