Background:
To explore the relationship between the morphological characteristics and pathological diagnosis of vocal cords leukoplakia.
Methods:
A total of 1635 vocal cords were collected. The morphology were classified into three types (Type I, II, III): flat and smooth; bulge and smooth; bulge and rough. The pathological reports were classified into five groups: no dysplasia, mild dysplasia, moderate dysplasia, severe dysplasia and cancerization. The number of the patients or vocal cords in each type and group was counted and their ratio was compared.
Results:
In Type I, the number of vocal cord in Group A group was 2.2 and 2.6 times of the one in Type II and Type III respectively. In Type II, the mild, moderate dysplasia ratio was higher than those in Type I. In Type III group the ratio of severe dysplasia was 2.6 and 5.5 times of the one in Type II and Type I respectively. The ratio of Group E in Type III was 2.7 and 7.9 times of the one of Type II and Type I. The result was significant (pearson Chi-square value was 517.6, p = .00).
Conclusions:
The pathological results of vocal cord leukoplakia can be evaluated by morphology in most cases.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...
01:27Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
