Overview

In 1875, Potain was the first who published a case of dermatomyositis documented in Europe.^[1]
In 1886, Urivericht was the first who described polymyositis.^[1]
In 1916, Stertz was the first who described the association between DM and malignancy.^[2]
In 1975, Anthony Bohan and James B. Peter were the first physicians who classified polymyositis and dermatomyositis into 5 subtypes which include:^[3]
- Primary idiopathic polymyositis (PM)
- Primary idiopathic dermatomyositis (DM)
- DM/PM associated with neoplasia
- Childhood DM/PM associated with vasculitis
- DM/PM with associated collagen-vascular disease
In 1991, Dalakas
By 1990, seven myositis-specific autoantibodies (MSA) were discovered and described. These myositis-specific autoantibodies (MSA) targeting different cytoplasmic ribonucleoproteins including
- Helicase protein (Mi2)
- Signal recognition particle (SRP)
- Anti-aminoacyl-tRNA synthetases such as
  - Histidyl (Jo1)
  - Threonyl (PL-7)
  - Alanyl (PL-12)
  - Glycyl (EJ)
  - Isoleucyl (OJ)
In 1991, Love et al. proposed another classification of idiopathic inflammatory myopathy based on myositis-specific autoantibodies (MSA).

In [year], [diagnostic test/therapy] was developed by [scientist] to treat/diagnose [disease name].
