Küttner's Tumor and Autoimmune Pancreatitis as Metachronous Manifestations of IgG4-Related Disease.

Immunoglobulin G4-related disease (IgG4-RD) is a multiorgan, fibro-inflammatory condition that presents with painless organ swelling, lymphoplasmacytic infiltration, and obliterative phlebitis, often showing a favorable response to corticosteroid therapy. The most affected organs include the pancreas, kidneys, retroperitoneum, lacrimal glands, and salivary glands. Diagnosis relies on serological, imaging, and histopathological findings, with glucocorticoids as the primary treatment. Despite its reversible nature and good prognosis in many cases, long-term complications such as organ dysfunction or malignancy can still occur. International collaborative efforts have enhanced the understanding, diagnosis, and management of IgG4-RD, emphasizing the importance of comprehensive diagnostic criteria and appropriate therapeutic strategies. Herein, we present an interesting case of a geriatric male who was referred to our clinic because of concern for pancreatic cancer. We diagnosed the patient with autoimmune pancreatitis, a manifestation of IgG4-RD. The patient experienced a dramatic response to steroid therapy and is currently on maintenance therapy.

A Plasmacytoma of the Lateral Pharyngeal Wall: A Diagnostic Enigma.

Plasmacytoma is a rare plasma cell dyscrasia that grows in bones or soft tissues such as the pharynx. Soft tissue plasmacytomas are rare, and a higher burden has been reported in the upper aero-digestive tract, often manifesting as hoarseness, dysphagia, or odynophagia. Due to their rarity, extramedullary plasmacytomas (EMPs) have unknown prognostic factors, and guidelines for optimal management are still lacking. However, radiation therapy and surgery have been used with positive outcomes. Herein, we describe a unique case of plasmacytoma of the pharyngeal tissue in a male patient with a history of HIV disease. The patient completed 28 sessions of radiation therapy, resulting in an improvement in his throat pain and hoarseness. Given the patient's age and lack of traditional risk factors for head and neck cancers, his hoarseness and odynophagia proved to be a diagnostic conundrum. Although infrequent, soft tissue plasmacytomas should be considered in the differential diagnosis of head and neck tumors.

Tuberculous Bronchopleural Fistula: A Rare and Life-Threatening Disease.

Tuberculous bronchopleural fistula (BPF) is a rare and potentially life-threatening complication of pulmonary tuberculosis, in which abnormal connections form between the bronchial tree and the pleural space. These abnormal connections allow air and secretions to pass from the lungs into the pleural space, causing a range of symptoms from benign cough to acute tension pneumothorax. The management of tuberculous BPF requires an individualized approach based on the patient's condition and response to treatment. Anti-tuberculosis therapy is essential for controlling the active tuberculosis infections. Intercostal drainage and suction are also commonly used to drain air and fluid from the pleural space, providing relief from the symptoms. For some patients, more invasive surgeries, such as decortication, thoracoplasty or pleuropneumonectomy are required to definitively close the fistula when medical management alone is insufficient. Herein, we describe a rare case of tuberculous BPF in a young adult female, who was treated with anti-tuberculosis medications and open thoracotomy.
