Inflammatory pulmonary pseudotumour is an uncommon, non-neoplastic, occasionally aggressive spindle cell proliferative process of uncertain nosology. It has distinctive histopathological features and benign clinico-biological behaviour with multifocal lesions or recurrences in a minority of cases. Recognition of this entity is of paramount importance because it has considerable therapeutic and prognostic implications. The radiological features of two patients with pulmonary pseudotumour that was confirmed on histopathological examination are described.

Feasibility of computed tomography-derived surgical margin assessment in an ex vivo sublobar lung resection model.

Objectives: Computed tomography imaging of a sublobar resection specimen may inform intraoperative surgical margin assessment. However, consistency with final pathological margins has not been previously evaluated. In this study, we investigated the concordance between surgical margin measurements by computed tomography versus pathology measurements using an ex vivo sublobar lung resection model.

Pseudotumors are a rare complication of total hip arthroplasty (THA), arising from local soft tissue reactions. These reactions can lead to painful joint effusions and prosthetic loosening, often necessitating revision surgery. Metal-on-metal and metal-on-polyethylene prostheses are particularly prone to this complication due to the accumulation of metal debris from prosthetic wear, which represents a significant drawback.

Background: Osseous tumors of the foot and ankle are rarely encountered in general orthopaedic practice and represent only 3 % of osseous neoplasms. It can be difficult to distinguish between benign and malignant lesions, leading to misdiagnosis. Delays in diagnosis are the main cause of litigation in sarcoma of the extremities.

Article Synopsis
- Therapy-related acute promyelocytic leukemia (t-APL) is a rare condition often arising from treatments like alkylating agents or topoisomerase II inhibitors.
- The report details three cases of t-APL at Cosenza Hospital, each requiring unique treatments following different cancer therapies.
- Notable outcomes include a complete remission in one patient treated with ATRA, while another faced severe complications but also achieved remission; the third patient, however, sadly died due to complications during treatment.
