Polymyalgia rheumatica (PMR) is characterized by stiffness and pain in the shoulders, hips and neck and presents most commonly in the eighth decade. It can coexist with giant cell arteritis and the two diseases may share some pathophysiological mechanisms. This narrative review considers present-day ideas about PMR in a historical context, from the first names and descriptions of this disease entity, via successive generations of classification criteria sets, and finally to implications for clinical diagnosis. The characteristic distribution of musculoskeletal inflammation in PMR and its relationship to vasculitic and synovitic diseases have framed the way that PMR is described, classified, diagnosed and treated. A response to glucocorticoids is not specific to PMR and so it is important for rheumatologists to support general practitioners in making a definite diagnosis. Multi-stakeholder collaboration will improve current pathways for fast, accurate diagnosis and safe and effective treatment., (© The Author(s) 2024.

Saint Martin of Leon was a monk who lived in the 12th century. The details of his life are known because they were described by his contemporary, Lucas de Tuy, in the Liber de Miraculis Sancti Isidori. Saint Martin of Leon was a venerable old man who suffered from severe headaches, considerable difficulties in raising or maintaining his arms raised, asthenia, and anorexia. In addition, he is represented in his codex Concordia with an unusual hyperpigmentation of the temples suggesting a therapeutic intervention on temporal arteries. These data lead us to think that this could be the first described case of giant cell arteritis with some clinical information. Moreover, he experienced a singular and curious appearance of Saint Isidore of Seville, who made him swallow a booklet, which might correspond to a complex visual hallucination or associated Charles Bonnet syndrome. Historical data on the disease are reviewed and discussed, as well as its evolution and treatment before giving steroids.

The author set out to review the thought processes of Bayard Horton as he was clinicopathologically describing the first cases of temporal arteritis. The Mayo Clinic records of the original temporal arteritis patients were examined. Horton obtained the first biopsies of the temporal arteries in temporal arteritis and was the first to describe the histopathology. Horton initially thought his first two patients had actinomycosis of the temporal arteries, but later abandoned this diagnosis. He reported these two patients in 1932 as 'an undescribed form of arteritis of the temporal vessels'. He was the first to describe jaw claudication. He saw a patient with blindness and symptoms suggestive of temporal arteritis before this complication was described in the literature, but initially felt the patient had some other disease. The sedimentation rate was elevated in his first patient. He cared for the first temporal arteritis patient ever treated with cortisone.

Purpose of Review: Recent developments in the nosology of primary systemic vasculitis are placed in the context of an historical overview. The ongoing attempts to develop criteria for classification and diagnosis are discussed., Recent Findings: Giant cell arteritis has supplanted temporal arteritis as the preferred term for chronic granulomatous arteritis in older adults. A new classification system for childhood vasculitis has been proposed by a European collaborative group. A study of idiopathic polyarteritis nodosa demonstrates greater similarity to microscopic polyangiitis in relapse rate than previously reported. Controversy has arisen over the eponym Wegener's granulomatosis because of alleged involvement of Friedrich Wegener in the Nazi regime during World War II. Diagnostic criteria for Kawasaki disease are problematic because many patients with coronary artery involvement do not fulfill current criteria at the time of presentation. Classification of antineutrophil cytoplasm autoantibody-associated small vessel vasculitis based on antineutrophil cytoplasm autoantibody specificity has been complicated by the finding that different ethnic groups may have very different clinical features relative to antigen specificity; for example, most patients with Wegener's granulomatosis in China have myeloperoxidase-antineutrophil cytoplasm autoantibodies rather than proteinase 3-antineutrophil cytoplasm autoantibodies., Summary: Within the past year, new classification systems for primary vasculitis have been proposed, new classification criteria have been developed, and the appropriateness of a longstanding eponym has been challenged.

Giant cell arteritis and polymyalgia rheumatica were described separately more than 100 years ago. However, the original reports of both conditions were neglected for many years. After the article by Horton et al on giant cell arteritis in the 1930s and studies published by others in the 1940s, giant cell arteritis began to be recognized as a specific disease. In the 1950s and 1960s, many of the numerous presentations and complications of giant cell arteritis were recorded. In a somewhat similar fashion, physicians became cognizant of polymyalgia rheumatica only after several independent descriptions in the 1940s and 1950s. The rapid response of both syndromes to glucocorticoid therapy was discovered shortly after cortisone's effect on rheumatoid arthritis was described. The origin of the proximal aching and stiffness in polymyalgia rheumatica was more difficult to understand. The relatively minor findings in the joints on physical examination seemed insufficient to account for the severe discomfort. As the link between polymyalgia rheumatica and giant cell arteritis became apparent, some thought the aching in polymyalgia rheumatica was related to vasculitis. The debate about whether proximal synovitis or vasculitis was the cause of the symptoms continued after 1970. Although the reason these 2 conditions were associated was not considered by 1970, the establishment of the syndromes as clinically linked entities provided the groundwork for further progress in the next decades.

Only two years separate the initial descriptions of polymyalgia rheumatica (PMR) by Bruce in 1888 and giant cell arteritis (GCA) by Hutchinson in 1890. However, the existence of an association between these two conditions was definitely accepted only in 1964. Even if PMR is generally accepted as a different disease from GCA, some authors deem PMR to be a manifestation of a generalised arteritis and use the term GCA to define PMR/GCA as a whole. The time has come to clarify this issue.

Realism is one of the characteristics of Amarnian art; some details of The Harpist represented in the tomb of Pa-Aton-Em-Heb (1350 BC, 18th Dynasty) might gives clues to a diagnosis: the eyes are closed with swollen lids, and the harpist appears to stare into space; he is round shouldered with a very wasted face, his temporal ara is heightened and hollowed by a broken line joining the extremity of the eyebrow with the corner of the eye. These details are not found elsewhere. Did the harpist's blindness result from temporal arteritis associated to polymyalgia rheumatica?

I present a bried review of Hutchinson's Archives of Surgery. I have listed most of his well-known and not-so-well-known early clinical descriptions. To this list can be added descriptions of Peutz-Jegher syndrome, lipomelanic reticulosis, telangiectatic lupus erythematosus, temporal arteritis, and recurrent herpes simplex on the thigh and buttocks. The characteristics of Hutchinson's writing are the use of catchy, descriptive terms, his use of patients' names for diseases, his belief in the effectiveness of illustrations, superb clinical observation but faulty conclusions, and a lack of humor. Seventy-two years after his death, there is still much that can be learned about clinical disease from Hutchinson.

In 1932, Horton, Magath and Brown reported two cases of a "new form of arteritis affecting the temporal vessels ... which probably represents a new clinical syndrome". In reality, several publications, devoted to the same pathology already preceded this article. The most ancient is that of an ophthalmologist from Baghdad, Ali Ibn Isa (940 to 1010). In his memories, translated and published in english in 1936, the author states that "he undertook excision and cauterisation of arteries to treat patients who were suffering from heat and inflammation of their temporal muscles and which sometimes ended in loss of vision ...". In 1890, J. Hutchinson, an English surgeon, reported a case "... of inflammed and swollen temporal arteries ...". This article was only brought to light in 1946. In 1930, M. Schmidt, published a probable case of temporal arteritis, subsequently reported in 1947. In 1934 and 1936, Horton published new cases of temporal arteritis and defined the clinical characteristics of the disease and its histology. In 1938, Jennings made a particular contribution in reporting the first case of blindness. From this time on, cases of temporal arteritis became increasingly common in the literature. The first French case was described by J. Paviot et al. in 1934, but remained largely unrecognized until 1942. In 1936, J. Chavany was the first to describe the pillow sign, but more particularly in 1948, he prescribed the first treatment with steroids, with spectacular results. It was only in 1950 that R.M. Shick et al. published the effects of steroid therapy in temporal arteritis.(ABSTRACT TRUNCATED AT 250 WORDS)
