Glomus coccygeum is a glomus body which is found in the pericoccygeal soft tissue. This specialised arteriovenous anastomosis is a non-pathological vestigial structure usually larger than its equivalent in the distal extremities. Its prevalence is uncertain. Glomus coccygeum has been associated with coccygodynia and can cause diagnostic problems to pathologists unfamiliar with this entity. ⋯ Glomus coccygeum is a common microanatomical structure which can be distinguished from glomus and other tumours by its small size, SMA expression and low proliferative activity.

Intra-articular injection is being used widely for both diagnostic and therapeutic purposes in the hip. However, its efficacy is not always predictable in patients with hip osteoarthritis (OA). The purpose of this study was to determine whether the degree of radiographic severity of OA was predictive of the response to intra-articular injection of local anesthetic with corticosteroid and to determine the relationship between immediate pain relief resulting from the anesthetic and delayed pain relief resulting from corticosteroid administration. ⋯ Pain relief following intra-articular hip injection correlated with radiographic severity of OA. This intervention may be of therapeutic and prognostic value in patients awaiting hip arthroplasty.
