Thirty-one patients with 46 digital mucinous pseudocysts are reviewed. The pseudocysts are usually soft, fluctuant, dome-shaped, dimpled, smooth lesions located near and often associated with a linear defect of the fingernail. Transillumination confirms the diagnosis. Treatment is conservative, usually consisting of intralesional injections. If surgery is necessary, distal interphalangeal joint injection of methylene blue aids in complete removal by identifying the mesothelial-lined pedicle leading from the distal joint to the pseudocyst.
回顾了31例患有46个指部黏液性假囊肿的患者。假囊肿通常为柔软、波动感、圆顶状、有凹陷、表面光滑的病变，位于指甲附近，且常与指甲的线性缺损相关。透照检查可确诊。治疗较为保守，通常采用病灶内注射。如有必要进行手术，向远侧指间关节注射亚甲蓝有助于通过识别从远侧关节通向假囊肿的间皮衬里蒂来完整切除病变。
