Shoulder abscesses, commonly resulting from bacterial infections, can occasionally present with atypical etiologies and delayed onset. We report a rare case of a massive polymicrobial shoulder abscess developing two decades after an insect bite, emphasizing its clinical presentation, diagnostic approach, and surgical management. A 65-year-old female presented with severe, progressively worsening right shoulder pain, a 20 cm swelling, and purulent discharge persisting for 15 days.

PbZrO (PZO) thin films, as a classic antiferroelectric material, have attracted tremendous attention for their excellent dielectric, electromechanical, and thermal switching performances. However, several fundamental questions remain unresolved, particularly the existence of an intermediate phase during the transition from the antiferroelectric (AFE) to ferroelectric (FE) state. Here, a phase coexistence configuration of an orthorhombic AFE phase and a tetragonal-like (T-like) phase is reported in epitaxial antiferroelectric PZO thin films, with thickness ranging from 16 to 110 nm.

Introduction: Tumoral calcinosis is a rare hereditary condition characterized by the deposition of calcium phosphate and hydroxyapatite in periarticular soft tissues. First described by Giard and Duret in 1898 and later detailed by Inclan in 1943, this condition has often been confused with other forms of periarticular calcification. Tumoral calcinosis predominantly affects young males and is typically found around major joints, such as the shoulder, elbow, hip, ankle, and wrist.

Excellent outcomes can be achieved with early surgical excision. Delayed presentations-as in this giant shoulder PTT-are made possible, in part, by patient education and healthcare accessibility in low-resource settings.

Serviço de Ortopedia e Traumatologia, Hospital Santa Rita de Cássia, Vitória, ES, Brasil.
Pigmented villonodular synovitis (PVNS) is rare in the shoulder, with few descriptions in the literature. We present the case of a 58-year-old female patient with no history of trauma. The patient reported pain for 2 months with no limb irradiation and presented lifting strength loss and progressive limitation of active and passive mobility.
