Introduction: Mucoid degeneration of the anterior cruciate ligament (ACL) is a very rare cause of knee pain. Patient having mucoid degeneration of ACL seeks multiple orthopedic consultation and most of the time treating orthopedican miss its diagnosis either because of lack of experience or rare cause of pain unless doctor sought magnetic resonance imaging (MRI) of knee.
Case Report: We report a case of mucoid degeneration of the ACL in a 50-year-old female with knee pain of 18 months duration. The patient presented with extension block of the knee. After arthroscopic debridement of the lesion, the patient regained full range of motion of the knee and were pain-free at follow-up.
Conclusion: A long duration of non-specific knee pain in a patient should be evaluated with MRI. Mucoid degeneration of the ACL is suspected when an apparently thickened and ill-defined ligament with increased signal intensity on all sequences in MRI is identified in a patient with physically intact ligament and no obvious trauma history. Arthroscopic debridement of the mucoid degeneration of the ACL was safe and effective in the patient.

Is calcification integral to enthesopathy and tendinopathy rather than a separate disease process?

Department of Surgery and Perioperative Care, Dell Medical School-The University of Texas at Austin, Austin, TX, USA.
Background: The pathophysiology of enthesopathy and tendinopathy is mucoid degeneration, which includes chondroid metaplasia. The chondroid metaplasia can be associated with calcification. Inflammation is typically absent unless calcification triggers a self-limited immune response representing acute calcific tendinitis.

Introduction: Mucoid degeneration of the cruciate ligament is a well-known entity, but symptomatic lesions are rare. It is even rarer to find symptomatic posterior cruciate ligament mucoid degeneration than the anterior cruciate ligament.
Case Report: A 63-year-old male presented to our hospital complaining of posterior knee pain was induced when the knee approached full flexion without episodes of trauma, despite conservative treatment over the preceding 8 months, his symptoms persisted.

To investigate the clinicopathological features of orbital and eyelid inflammatory myofibroblastic tumors (IMTs). A retrospective analysis was conducted among 13 patients with IMTs treated at Tianjin Eye Hospital between January 2000 and October 2023. The clinicopathological data, immunohistochemical staining characteristics, molecular phenotypes, and follow-up outcomes were collected and analyzed.

Anterior cruciate ligament (ACL) mucoid degeneration is an underdiagnosed condition that occurs when mucinous material develops in the ACL in the absence of synovial lining. Several authors have diagnosed this condition, discussed their own personal observations, and put forward their own suggestions for management. When diagnosed, one important strategy for management entails "debulking" the ACL using an arthroscopic debridement.

To document a case of `preliminary` identification of Alternaria sp (a phaeohyphomycotic agent) based on morphology in tissue section in a patient with allergic fungal rhinosinusitis. A 25-year-old male, a known asthmatic in a post Covid -19 state, presented with headache, facial swelling and nasal block with discharge of brownish mucoid material. Debrided material from the right maxillary antrum and middle turbinate showed brownish mucoid material admixed with firm to hard degenerated bony spicules sent in formalin and subjected for histopathological examination.
