Granulomatous myopathies are rare. Most cases are associated with sarcoidosis. We report a case of granulomatous myopathy associated with primary biliary cirrhosis, pancytopenia, and thymoma. The literature in regard to granulomatous myopathy and its pathogenesis is reviewed. Intermittent pulsed intravenous methylprednisolone may be useful as maintenance therapy for granulomatous myopathy and other neuromuscular syndromes for patients intolerant of oral corticosteroids.

Objectives: Granulomatous myositis (GM) is a rare entity whose precise clinical features and therapeutic outcomes have not yet been well defined. Given the limited evidence, data from a large cohort of patients is needed to aid in the recognition and management of this condition.
Methods: We retrospectively analyzed our institutional databases to identify patients who had myositis and non-caseating granuloma on muscle biopsy (GM).

Sarcoidosis is a multisystem granulomatous inflammatory disorder, of unknown aetiology, which causes a wide spectrum of clinical phenotypes. It can present at any age, most commonly between 20 and 60 years, with a roughly equal sex distribution. Diagnosis is often delayed due to multiple diagnostic mimics, particularly joint disease.

While the skin is a common target organ for sarcoidosis, cutaneous granulomatous vasculitis is rare among patients with sarcoidosis. Due to the lack of detailed studies on cutaneous sarcoid vasculitis, both dermatologists and pathologists remain unfamiliar with this rare but important vasculitic disorder. We clinicopathologically evaluated eight cases with biopsy-proven cutaneous vasculitis and cutaneous sarcoidosis and analyzed morphologic changes in the process of vasculitis for both small vessels and muscular vessels in detail.

Article Synopsis
- * A case study details a 25-year-old male diagnosed with MRS, who later developed temporomandibular joint osteoarthritis (TMJ-OA), treated successfully through a combination of surgery and medications.
- * The research suggests MRS may be a systemic autoimmune disease that could also affect the onset of TMJ-OA, highlighting the importance of understanding immune mechanisms in treatment.
A Curious Case of Weakness: Antineutrophil Cytoplasmic Antibody-Associated Vasculitis Presenting With Muscle Weakness.

Pathology, Arkana Laboratories, Little Rock, USA.
Disease manifestations of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), a small vessel vasculitis with multisystemic effects, include respiratory, renal, nervous, gastrointestinal, and skin implications. Muscle weakness and inflammatory myopathy are rare manifestations of AAV. We report the case of a 77-year-old female with a medical history of hypothyroidism and osteoarthritis who presented with a two-month history of worsening muscle weakness (mainly proximal).
