Ponatinib-Induced Pneumonitis with Severe Acute Respiratory Distress Syndrome.

Unlabelled: Ponatinib is a third-generation tyrosine kinase inhibitor (TKI) that can effectively treat patients with acute lymphoblastic leukaemia (ALL), particularly those with Philadelphia chromosome-positive (Ph+ALL) subtype, who are resistant or have previously received other TKIs. We report a case of a 42-year-old female with Ph+ALL who was admitted to the intensive care unit with respiratory failure and severe acute respiratory distress syndrome (ARDS), while on treatment with ponatinib. Despite being treated with multiple antibiotics and antivirals, the patient's condition continued to worsen, and pulmonary complications secondary to TKI were suspected.

Kikuchi-Fujimoto Syndrome: A Rare Entity to Consider.

Introduction: Kikuchi-Fujimoto disease (KFD) is a rare, benign, necrotizing lymphadenitis of unknown aetiology with good prognosis. It is characterized by cervical lymphadenopathy, nocturnal diaphoresis and fever. Surgical excision of the adenopathy, histopathological study and immunophenotyping are crucial for diagnosis.

Hepatosplenic T-Cell Lymphoma: A Rare Complication of Monotherapy with Thiopurines in Crohn's Disease.

Hepatosplenic T-cell lymphoma (HSTCL) is an extremely rare and aggressive form of non-Hodgkin lymphoma associated with poor response to treatment and high mortality. There is an increased incidence among patients with inflammatory bowel disease, especially young male patients under 35 years old and on combination therapy (thiopurine and anti-TNF-α). We describe a case of HSTCL in a young male patient with stenosing ileal Crohn's disease on azathioprine monotherapy for 4.
