Depending on the results of histology, pseudomilima can be of different types. It is worth mentioning that the term “pseudomylum” is often used by other specialists and denotes a different phenomenon, which we will discuss later.
Since Psedomilum is a pseudo-disease, the exact diagnosis will be: Pachyonychia rubica
Pseudomylum, or pachyonychia, involves a not entirely natural development of the edges of the nail plate. This form of the disease is characterized by clearly defined lines of contact between healthy and damaged tissues. Thus, the appearance of the nail becomes very rough. Pachyonychma occurs primarily on the fingernails, but can also occur on the toes. Usually by mid-life the infection penetrates the tips of the phalanges of the fingers. False-keratin structures form above the lunula. Often the shape is oval or round, sometimes bulbous
